▼ Australian First World War historiography tends to focus on the ordinary soldier: his background, character and involvement in the war. This is a legacy left by Charles Bean who, following the history from below approach, believed in the need for soldiers’ stories to be told. On the other end of the spectrum, attention is given to political leaders and the British high command. British commanders and, by extension, other Allied commanders are too often portrayed as poor leaders who were reluctant to adapt to modern warfare, and did not demonstrate a sense of responsibility for the men under their command. The evidence shows that this perception is not accurate. A comprehensive understanding of the progression of Australian forces on the Western Front cannot be gained without investigating the progression of those in command.This thesis examines the brigade commanders of the Australian Imperial Force who held that level of command for a substantial period while on the Western Front. These commanders challenge preconceived notions of First World War commanders, as they continually developed tactics and adapted to modern warfare as it evolved. They embraced new technology and ensured that their formations were able to effectively work with it. As the war progressed, they gained an appreciation of the importance of collaborating with other formations and ensuring effective communication, and demonstrated an understanding of the challenges of war on the Western Front. By 1918, the brigade commanders were effective leaders who undoubtedly played a significant role in the success of the Australian forces.

▼ 1) An investigation was undertaken into the various activity rhythms found in the larvae of Myrmeleon obscurus (Neuroptera, Myrmeleontidae). Pit construction was used as the criterion of activity. 2) The capacity sensitive electronic circuit used to monitor the daily pit building activity is described. 3) Various factors affecting the size of the pits constructed by ant-lion larvae were investigated. Pit size was found to be correlated with the size of the larvae, larger larvae constructing bigger pits. Population size was also shown to have an effect, since the more crowded the animals were the smaller and closer together their pits became. The death rate due to competition between the larvae also increased as the ant-lions became more crowded. 4) Feeding frequency also affected pit size. Ant-lions which were starved constructed very small pits. 5) Pit size was affected by the texture of the sand, maximal pit size being attained in sand with a grain size of between 353 μ and 211 μ. This was shown to be the most abundant grain size in sand from the natural habitat. In sand coarser or finer than this, pit size was reduced. 6) Generally smaller pits were constructed at lower temperatures, but this response depended largely on the lunar cycle. The upper and lower critical limits for pit construction were found to be 11° C and 42° C. Below and above these temperatures no pits were constructed, although the ant-lions remained alive. 7) Daily destruction of the pits decreased the pit size. 8) The existence of the daily pit building activity rhythm, which occurs at dusk, was demonstrated in individuals and in populations of ant-lion larvae. This rhythm was studied using the capacity sensitive circuit, and also by direct observation of groups of animals over a 24 hour period. 9) The daily activity rhythm appeared to be endogenous, since it continued for at least a month both in constant light and in constant dark. The rhythm was altered by reversals in the daily light-dark cycle, and it was concluded that light was the main phase setting factor. 10) An attempt was made to determine the location of the "clock" or "clocks" controlling the daily activity rhythm. This was investigated by chilling the heads of individual ant-lions with a fine copper wire, and also by chilling large groups of animals in the refrigerator. From these experiments no definite conclusions could be drawn about the location of the "clock". 11) The existence of a lunar pit building cycle was demonstrated in both field and laboratory populations of ant-lions. Maximal pit size was attained at full moon. Very low temperatures were found to suppress these lunar peaks. 12) The lunar pit building rhythm was shown to be endogenous, since it continued for at least two months in constant dark and one month in constant light. 13) The lunar pit building rhythm of very young larvae was investigated, and it was shown that while larvae which hatched in the field appeared to possess a lunar rhythm, larvae which were hatched in the laboratory did not have a rhythm.

▼ From Introduction: Larvae of the families Myrmeleontidae, Neuroptera, (ant-lions) and Rhagionidae, Diptera, (worm-lions) all live in hot dry sand. Many of the ant-lion larvae and all the worm-lion larvae, construct small conical pits in the sand which are used for the capture of prey (Haub, 1942; Youthed and Horan, 1969a). Those ant-lion larvae which do not construct pits lie in wait for their prey just below the surface of the sand.

▼ Vibrissae (whiskers) are important components of the mammalian tactile sensory system, and primarily function as detectors of environmental vibrotactile cues. Pinnipeds possess the largest and most highly innervated vibrissae among mammals and their vibrissae demonstrate a diversity of shapes and likely mechanical properties. These two characteristics are important for vibrotactile sensory perception.
Vibrissae of most phocid seals exhibit a beaded morphology with repeated sequences of crests and troughs along their length. I comparatively characterized differences in vibrissae morphologies among phocid species with a beaded profile, phocid species with a smooth profile, and otariids with a smooth profile using traditional and geometric morphometric methods to test the hypothesis that vibrissal morphologies are species-specific manipulations of a common pattern. The traditional and geometric morphometric datasets were subsequently combined by mathematically scaling each to true rank, followed by a single eigendecomposition. Quadratic discriminant function analysis demonstrated that 79.3, 97.8 and 100% of individuals could be correctly classified to taxon based on vibrissal shape variables in the traditional, geometric and combined morphometric analyses, respectively. At least three separate morphologies were identified since phocids with beaded vibrissae, phocids with smooth vibrissae, and otariids each occupied distinct morphospace in the geometric morphometric and combined data analyses.
Another important characteristic that influences the transduction of vibrotactile information to the mechanoreceptors in the follicle-sinus complex is the materials properties of the vibrissae. Vibrissae were modeled as cantilever beams and flexural stiffness (EI) was measured to test the hypotheses that the shape of beaded vibrissae reduces flexural stiffness and that vibrissae are anisotropic (orientations differ in EI). Species were significantly different and smooth vibrissae were generally stiffer than beaded vibrissae. Beaded vibrissae decrease vibrations in flow, which, combined with lower flexural stiffness values, may enhance detection of small changes in flow from swimming prey. The anterior plane of the vibrissae is likely the most biologically significant in tracking hydrodynamic trails but had lower flexural stiffness values than the dorsoventral orientation. There is likely a complex interaction between shape and mechanical properties in pinniped vibrissae but the ecological and functional implications are currently unknown.

▼ My thesis concerns observations of play activities from videotapes of Galápagos sea lions on San Cristóbal Island from mid-summer of 2008. I begin with a discussion of ideas about play and types of play, elaborate the conceptual system of projects and routines in play, and provide a brief description of sea lion taxonomy and forms of play specific to Galápagos sea lions. Observing approximately 713 minutes of videotapes, I coded approximately 161.5 minutes of play projects and routines. Of the 713 minutes, 241 minutes were used in training, and 472 were coded independently by two coders for reliability. The two coders observed approximately 141 minutes of play. For the presence of particular projects and routines at approximately the same time, reliability was 100%; for agreement about the temporal extent of projects and routines, reliability was 96% (though some infrequent projects and routines had low agreement); overall, Cohen’s kappa was .97. I observed five solitary play projects (lolling, twirling, object play, jumping, and surfing), and four social play routines (playfighting, playchasing, playwrestling, and king of the hill—a form of playful boundary defense). Of these, lolling and twirling had not been previously coded as play in the scientific literature. The most common play activities were lolling and playfighting. Social object play, sexual play, and boundary defense seem likely to be present in all sea lion species, but I observed no evidence of the first two, and only one variant of boundary defense (king of the hill), in the videotaped Galápagos sea lions.

▼ This thesis explores the interaction between natural and urban life through mutual recognition, viewing the clash of territorial borders as dynamic conditions rather than exclusion zones. Gir area in India has been investigated as a unique case where humans and lions for centuries have lived together and established a mutual respect. Rasulpara village is used as a local situation to analyze the relationship between humans and animals with the intention to understand how such relationship can be maintained. It has led to the recognition of the in-between as intermediate zones mediating exchange between the two systems. With humans relating to settled form as territorial constrains, the language of architecture becomes a messenger of a respect playing with a time-based system; mediating the balance between safe and unsafe. Learning from the existing relationship of mutual understanding aims to extract lessons for how to intervene in the context and other mediation areas between human and wild. Exploring these attributes through design has shown that built form can act as solid borders to classify and preclude, but also to invite cohabitation by respecting means of existence. Territorial conflicts can then be dealt with more sensitively, thus obtaining the equilibrium within a changing world anchored in traditional knowledge.

▼ Embora inúmeras coleções de plantas e observações pontuais sobre a distribuição da vegetação ao longo do Continente Antártico têm sido feitas desde o final do século XIX, pesquisas botânicas com ênfase nas relações ecológicas têm sido relativamente limitadas. O presente trabalho, enfocou estudos ecológicos em duas importantes áreas livres de gelo segundo um gradiente climático, e foi dividido em dois capítulos. No primeiro capítulo objetivou-se estudar a estrutura das distintas comunidades vegetais correlacionando-as aos aspectos ambientais, especificamente pedológicos, da região sudeste da Ilha Rei George, conhecida como
Lions Rump. Para isso, procedeu-se a abertura de perfis de solos em cada uma das 9 comunidades estudadas. Também foram levantadas a composição e cobertura da vegetação pela implantação de 30 parcelas de 25X25 cm nas respectivas comunidades. A Análise de Correspondência Canônica (CCA) foi utilizada para verificar o papel dos atributos dos solos sobre a distribuição das comunidades amostradas. Três diferentes fitofisionomias foram reconhecidas a partir da análise fitossociológica, as quais, através da CCA, apresentaram relações distintas com os solos associados. Os resultados demonstraram que a vegetação de
Lions Rump distribui-se em Comunidades de Usnea associados a solos e substratos de pH básico em áreas de maior elevação, e comunidades de Deschampsia das áreas litorâneas, associadas com teor e saturação por Sódio relativamente maior. A comunidade de musgos dominada por Sanionia uncinata formou um grupo distinto, estando relacionada a outros parâmetros ambientais, como maior umidade, não quantificados no presente trabalho. O segundo capítulo teve como objetivo estudar a composição florística das comunidades vegetais encontradas na região da Península Antártica, observando os aspectos ambientais relacionados e mapeando as áreas de ocorrência. A amostragem consistiu de 146 amostras aleatórias em 15 pontos de coleta de Hope Bay. Assim foram observados dois fragmentos formados por Usnea antarctica, cinco fragmentos contendo Umbilicaria decussata, uma comunidade de Caloplaca sublobulata, duas grandes comunidades formada principalmente por Rhizoplaca aspidophora e Acarospora macrocyclos, três pequenas formações de Caloplaca sublobulata, dois fragmentos dominados por Rhizoplaca aspidophora e um formado por apenas Acarospora macrocyclos. As principais espécies de musgos observadas foram Polytrichum strictum, Syntrichia princeps e Ceratodon grossiretis, e os mesmos ocorrem em duas ou mais comunidades. As comunidades de Prasiola crispa ocorrem preferencialmente ao redor das muitas pinguineiras formadas por populações de pinguins Adeliae (Pygoscelis adeliae). A afinidade dessa comunidade com elevadas concentrações de nutrientes, principalmente nitrogênio, explica a ocorrência dessas comunidades próximas as pinguineiras, assim como as comunidades de líquens ornitocoprofilos como Caloplaca e Acarospora. As demais comunidades ocorrem em áreas distantes das anteriores, onde fatores como a disponibilidade de água…

"This study compared and contrasted knowledge and attitude effects from a theme and zoological park sea lion show with shared educational objectives. Both programs aspired to foster curiosity and appreciation for species conservation. During summer 2010, 580 retrospective pretest-posttest surveys were distributed to visitors. Respondents agreed (n=532, 92%) sea lion shows were positive learning experiences, however, species conservation knowledge and attitude impacts differed between show types. Data showed a possible link between presenting species conservation information and increased positive environmental attitudes. Other factors such as visitors' preconceived expectations and attendance motivations may have affected facility success in achieving show conservation objectives. Results highlight the importance of evaluating animal shows to ensure visitors receive conservation messages" – Abstract.

▼ Feline herpesviruses are endemic in free-ranging
lions in South Africa. Serological surveillance among free-living
felids revealed high levels of exposure to the virus. However,
clinical disease in wild felids following FHV-1 infection has been
only described in captive populations and reported to be similar to
that in the domestic cat. To expand the epidemiological
understanding of feline herpesviruses in felids and for disease
control, three strains of FHV-1 isolated from a domestic cat (Felis
catus) a cheetah (Acinonyx jubatus) and an African wild cat (Felis
silvestris) have been compared to determine their relatedness. A
region of the herpesvirus DNA polymerase gene was amplified in a
nested PCR with consensus degenerate primers to confirm the
identity of the isolates. The genetic relatedness were investigated
by comparing patterns of genomic DNA cleaved with restriction
enzymes SalI and KpnI and the DNA fingerprints generated by
different RAPD primers. For antigenic relationships, a panel of
nine monoclonal antibodies prepared against a vaccine strain used
against domestic cats were tested in a microneutralization assay.
In addition, the phenotypic characteristics of the isolates were
also compared by their ability to produce plaques in CrFK monolayer
cell cultures. With restriction enzyme analysis, it was not
possible to make a comparison due to lack of digestion of the
genomic DNA of the domestic cat isolate. However, the RAPD-PCR
revealed that isolates were closely related but distinct from each
other. Only two monoclonal antibodies reacted with the wild
isolates; an effect similar to a toxic effect on cell was observed
with the domestic isolate. No significant differences of plaque
production were observed among the trains. This study provides
evidence of a closer evolutionary relationship between the three
isolates. The results of the relationships based on the genetic and
phenotypic characterization agreed well and both indicated that the
viruses from the domestic and wild felids are different but have a
high degree of similarity. Copyright

▼ In this research project steps toward the development of an IFN-gamma ELISA for the diagnosis of bovine tuberculosis in
lions are made. Two different existing IFN-gamma ELISA’s were studied and tested. An ELISA, previously developed for the detection of recombinant rhinoceros IFN-gamma (Morar et al. 2007), was used to determine detection of recombinant feline IFN-gamma. An adapted feline IFN-gamma ELISA, developed by Rhodes et al. (2008) was the other ELISA system that was used in this research. Blood samples from both domestic cats and
lions were collected and processed for use in the two different ELISAs that are mentioned above. Inconclusive results were obtained during this study, however this report describes the various steps that were performed and results obtained during a research period of three months.

▼ Corneal opacities and corneal ulcers are frequently observed in captive California sea
lions.
The objective of this research project was to investigate the influence of water quality on these eye problems. The diagnostic aid of fluorescein dye in corneal defects was also tested.
For six weeks two sea
lions and their corneal lesions were followed and water quality (Chlorine, salinity and pH) was tested every day.
It appeared that the concentrations of total, free and combined Chlorine had a significant influence on the size of the corneal lesions, whereas combined Chlorine had the most significant influence. It also appeared that not all the lesions were positive with fluorescein. However, fluorescein can be a useful diagnostic tool to determine the seriousness of the corneal lesions.
Since organic material increases the concentration of combined Chlorine, and this study demonstrated that corneal lesions are most severely affected by combined chlorine, it is recommended to decrease the organic material in the water and to use an alternative for Chlorine, such as a biological filter.

▼ O estudo da morfologia testicular e do processo espermatogênico em animais selvagens é fundamental para o conhecimento de padrões fisiológicos, pelos quais podem-se estabelecer protocolos em reprodução assistida. Os objetivos deste estudo foram descrever dados de morfometria testicular e túbulo seminífero, quantificar as relações populacionais do epitélio seminífero, índice de células de Sertoli e a reserva espermática testicular, e ainda, caracterizar e descrever o arranjo dos componentes do espaço intertubular, em leões africanos (Panthera leo) adultos, mantidos em cativeiro. Para tal, foram utilizados fragmentos testiculares obtidos de cinco leões adultos, provenientes de Parques Zoológicos dos Estados de São Paulo e Minas Gerais, os quais foram submetidos a biópsias testiculares a fim de se obter material biológico para avaliação histológica dos fragmentos obtidos. Nos animais estudados, o peso corporal médio foi de 183,7 kg, dos quais 0,015% estão alocados em massa testicular e 0,009%, especificamente em túbulos seminíferos, os quais representaram 75,6% do parênquima testicular. O diâmetro médio dos túbulos seminíferos foi de 252,7μm e a espessura média do epitélio seminífero foi de 93,2μm. Os leões africanos apresentaram, em média, 12,3 metros de túbulo seminífero por grama de testículo. No epitélio seminífero destes animais, 10,3 espermatócitos primários em pré-leptóteno são produzidos por espermatogônias do tipo A. Durante as divisões meióticas, apenas 2,7 espermátides foram produzidas a partir de espermatócitos primários. O rendimento geral da espermatogênese de leões africanos mantidos em cativeiro foi de 22,1 células e, cada célula de Sertoli, foi capaz de sustentar e manter 14,9 células da linhagem germinativa, das quais 7,9 são espermátides arredondadas. A cada ciclo do epitélio seminífero, cerca de 103 milhões de espermatozóides são produzidos por grama de testículo. Em relação ao compartimento intertubular do testículo de leões africanos, cerca de 16% do parênquima testicular é ocupado por células de Leydig, 7,1% por tecido conjuntivo e 0,7 % por vasos sanguíneos. O volume médio das células de Leydig e o seu diâmetro nuclear médio, encontrados foram, respectivamente, 2578 μm3 e 7,1 μm. As células de Leydig ocuparam em média 0,0019% do peso corporal e seu número médio por grama de testículo apresentou-se superior ao encontrado para a maioria dos mamíferos, ultrapassando os 50 milhões.
The study of the testis morphology and the spermatogenetic process in wild animals is fundamentally important for the knowledge about the physiologic patterns by which the assisted reproduction protocols are established. The following objectives were proposed in this study: to describe the data of both testis morphometry and seminiferous tubule; to quantify the population relationships of the seminiferous epithelium, Sertoli cell indexes, and the testis spermatic reserve, as well as to characterize and describe the arrangement of the intertubular space components in adult African lions (Panthera leo)…

▼ The biology of southern African Myrmeleontidae and Nemopteridae (Neuroptera, Myrmeleontoidea) was studied with special emphasis on the nemopterid subfamily Crocinae. The superfamily Myrmeleontoidea is considered to be a monophyletic group derived from ancestors similar to the family Nymphidae. The Myrmeleontidae and Nemopteridae are the most highly evolved families, and the Nemopteridae have a sistergroup relationship with the other four myrmeleontoid families. Within the Nemopteridae, the Crocinae are considered more advanced than the subfamily Nemopterinae. An account of previous work on the two families is presented: literature relating to the Myrmeleontidae is catalogued in appendix 2 and publications dealing with the Nemopteridae are surveyed in the text . Biological and morphological information derived from the immature stages as well as the adults was used in the systematic study of the two families. The geographical distribution and phylogeny of the Myrmeleontoidea is discussed with particular reference to the Myrmeleontidae and Nemopteridae. The Myrmeleontidae have a world wide distribution whilst the Nemopteridae are more restricted, being limited to the arid and semi-arid regions of the world. It is concluded that the two families originated on Gondwanaland, and their present distribution is explained on the basis of evidence provided by plate tectonics. In southern Africa, the Myrmeleontidae show two distributional trends: there is a distinct western fauna including many endemics and an eastern fauna which comprises taxa with a wide distribution in central and east Africa, extending their ranges into the eastern parts of the subregion. The Nemopteridae occur predominantly on the western side of the subcontinent and over 90% of the species are endemic to southern Africa. A systematic revision of the southern African Crocinae is presented and summarized in a set of illustrated keys to the adults and larvae. There are now ten known crocin species in four genera from the subregion, four species being described for the first time in this thesis. The larvae of all ten species and the eggs of seven, have been correlated with the adults and are described. Two crocin genera, Concroce and Thysanocroce, have larvae with short prothoraxes, whilst those in Laurhervasia and Tjederia are elongated. Larvae of the first two genera live in plant detritus under rocks and in crevices whereas larvae of the latter two genera inhabit small dusty caves. These findings on the Myrmeleontidae and Nemopteridae are discussed in the context of general systematic theory, phylogeny and zoogeography.

▼ African Lions (Panthera leo) are an keys species in many natural
ecosystems in Africa and provide income and ecosystem services to
many human communities. They directly limit herbivore
populations, which in turn maintain grasslands and associated
systems. Those ecosystems have degraded in recent decades and the
concurrent decline in lion population is believed to play a role.
I investigated factors affecting lion behaviour and ecology
including the effect of seasonal variation in wild prey herd
size. Current levels of herbivore prey are significantly lower
than before the creation of countrywide veterinary cordon fences
and total lean season biomass was estimated at 375.5 kg.km-2. I
placed GPS position locating radio collars on 13 lions in 6
prides in a study area of approximately 9,911 square kilometres
in the north of the Central Kalahari Game Reserve (CKGR), in
central Botswana. The collars acquired total of 241,858 usable
GPS fixes and I visited each lion monthly. Lion spatial behaviour
appears to have changed in response to the decline in herbivores,
although there is only a small amount of historical data. Lion
home ranges were large (mean home range = 2116.5 km2, range
798.3- 4243.7 km2) compared to two prides from a study in the
1970s in the same area which had home ranges of approximately 337
km2. Those prides increased their range to today’s sizes only
in severe drought years, but rainfall during the study period was
high. I interpret this as evidence that seasonal lower herbivore
densities have increased lion ranges, and reduced the number of
lions in the CKGR. I estimate the current population in the study
area at 307 adult lions, or 3.1 lions per 100km2. During months
of high herbivore group densities, lions travelled further on a
daily basis (mean daily movement distance of 7,160 m at lowest
density, to 8,616 m at the highest density), and males on average
travelled significantly further each day than females (mean of
10,071.6m per day for male, SD = 7099.4, maximum 48,462m and a
mean of 7,633.6m per day for females, SD= 5,069.3m, maximum
29,470m). Females moved similar distances daily even while
supporting cubs under 3 months old. Lions significantly preferred
hunting prey species above 90kg, but also hunted the smaller
warthog (Phacochoerus africanus) and African porcupine (Hystrix
africaeaustralis). This has implications for conflict mitigation
and lion conservation. I investigate the economics and extent of
the lion livestock conflict in Central Botswana and explore
potential management options in light of this new data.
Management options should be carefully selected with
consideration for economics, politics and local conditions, and
should target locations where conflict mitigation can have the
greatest benefit for both lion conservation and economic
improvement of…

▼ Humans, livestock, and lions have inhabited shared landscapes in northwest Namibia for hundreds of years. Currently, human-lion conflict (HLC) threatens pastoral livelihoods and the viability of the region’s desert-adapted lion population. In this dissertation I examine the history of human-livestock-lion relationships in the region. The goal is to create historically-informed solutions to HLC that are locally-inclusive. Drawing on archival, scientific, and governmental material, as well as social surveys and oral histories that I have performed, this is the first time that the disparate sources on human-livestock-lion relationships in northwest Namibia have been unified. While scholars of African environments have problematized interpretations of Africa’s environmental colonial and postcolonial past, this is the first work to examine human-predator relationships as a fulcrum for understanding colonial and postcolonial politics and the current challenges of conserving African lions. As a document informing ongoing conservation interventions, this is the first attempt to explicitly frame applied lion conservation activities within historical contexts, critically assessing livestock as mediators of human-lion interactions. I begin by showing how the precolonial and early-colonial experience of the region’s ovaHerero people was mediated through the control of livestock. I then examine how colonial era policies remade, and were aided by, the geography of predators. The effects of apartheid on the region’s wildlife showcase some of the important legacies of colonial-era policies. I then reveal the long history of human-lion interactions with particular emphasis on the transformative role of livestock. I then focus on the behavior and ecology of the desert-adapted lions, highlighting important contrasts with other lion populations and emphasizing how recent monitoring induced a paradigm shift. Finally, I center ongoing HLC within communal rangelands as experienced by pastoralists and suggest one way of reframing HLC that is founded in local perspectives.

lions have been around for about 12 million years,
but lately, they are moving into human territory in Newport Harbor.
Boat owners, residents and fishermen are sick of having to duke it
out for turf in this posh part of town. – But perhaps sea
lions
are showing up for good reasons – the harbor is safe, and the food
supply good. And while people complain about their loud barking,
unsavory hygienics, and their ability to steal a fisherman's catch,
humans are harming them at an alarming rate.

▼ Previous work in the Gulf of
Lions, France has suggested that significant amounts of sediment may be escaping through the western part of this tectonically passive margin, despite it being far-removed from the primary sediment source (the Rhone river, ~160 km to the NE). It is hypothesized that the westernmost Cap de Creus canyon is intercepting the regional sediment-transport pathway and directing it offshore, allowing significant sediment export through this area. The overall goal of this project is to determine pathways and causes of sediment movement into Cap de Creus canyon to determine its role in off-shelf sediment export within the Gulf of
Lions. Box cores were collected within the canyon and on the adjacent shelf on five cruises (2003-2005). Geochronology (210Pb-derived accumulation rates), grain-size distributions, and sedimentary structures (x-radiography) were analyzed to assess sedimentation patterns. Results indicate two mid-depth shelf depocenters (30-90 m water depth) separated by a zone of bypassing created by current acceleration around a headland. Within the canyon, the northern flank and mid-depth thalweg are modern depocenters of fine-grained sediments. The canyon head and southern flank are considered non-depositional for fine grains, although the head may be accumulating sands. Material enters the canyon from the northern rim (via advection of shelf benthic nepheloid layers), the southern rim (via dense-water cascading off the shelf), and through the canyon head (primarily coarse-grains). Budget calculations indicate that 9-23% of the sediment input to the Gulf is sequestered on the shelf and 1-4% is accumulating in upper Cap de Creus canyon. An ephemeral mud layer within the canyon axis indicates rapid deposition and frequent flushing, suggesting that sediment is moving through the upper canyon. This is also supported by high suspended-sediment concentrations associated with off-shelf dense-water flows. This study suggests that Cap de Creus canyon is an important conduit of sediment past the shelf break and the western margin is a primary location of sediment export from the Gulf of
Lions.

▼ The New Zealand sea lion (Phocarctos hookeri) is an endangered pinniped endemic to New Zealand (Wilkinson, Burges et al. 2003). Declared “nationally critical” under the NZ threat classification system and “vulnerable in decline” by IUCN, they have shown a 49% decline in pup production since 1995 (Chilvers, Wilkinson et al. 2010). I investigated the role of long-term changes in diet on the population ecology of NZ sea lions. I was interested in the role played by long-term changes in diet into the observed decline of the sea lion population. My study is set apart from others in that it spans 13 years of routine sampling, and represents one of the longest timelines of diet data for any pinniped species. I used scat and regurgitate samples from New Zealand sea lions that were collected at the Auckland Islands between the summer of 1995/1996 and 2012/2013. I identified 11 main prey types from hard parts including otoliths, beaks and other diagnostic bones. In scats these main prey types were opalfish (Hemerocoetes spp.), rattail (Macrouridae), red cod (Pseudophycis bachus), octopus (Octopus sp.) and arrow squid (Ommastrephidae), Ling (Genypterus blacodes), smallscaled cod (Paranotothenia sp.), hoki (Macruronus novaezelandiae), triplefin (Tripterygiidae), fur seal (Arctocephalus forsteri) and giant octopus (Enteroctopus zealandicus). Main prey types found in regurgitates were similar but there was a higher proportion of cephalopods than in scat samples. When assessing long-term trends in occurrence of main prey species I found that smaller prey types such as opalfish and Octopus sp. have been increasing in the diet over time, while larger species hoki and giant octopus have been decreasing. The ratio of fish:cephalopods in NZ sea lion diet has also been decreasing with time, possibly indicating an overall reduction in diet quality. I used catch per unit effort as a proxy for prey availability in the environment and compared this to frequency of occurrence (%FO) of main prey types over time. The best models for functional response by sea lions to increased prey availability were those that incorporated random variation among years, suggesting that abundance of prey species is not the only variable affecting intake of prey by NZ sea lions. Resource competition or habitat destruction imposed by fisheries could restrict intake by sea lions, or force prey shifts to species not commercially harvested. Lastly, I investigated age-related survival and breeding probability of NZ sea lions with reference to the amount of main prey species in the diet over time. Models were run to test the relationship between each prey type, and breeding and survival probabilities over time. Survival probability is best explained by the null model, indicating that survival is not significantly affected by the amount of any one prey type in the diet. Smallscaled cod and hoki have the best predictive capacity after the null; hoki was correlated with an increase in survival for all age groups, while smallscaled cod predicted an increase in survival for…

▼ Local human communities within Queen Elizabeth National Park (QENP) were surveyed to determine prevalent attitudes toward lion conservation efforts and Uganda Wildlife Authority’s (UWA’s) Revenue Sharing Program. Other objectives of the surveys were to obtain information about the frequency and conditions where the human-lion conflict occurred in QENP communities, the nature and extent of the consequences, and the communities’ perception of the main causes of human-lion conflict and their proposed conflict mitigation solutions. A further aim was to determine the effects of the UWA’s Revenue Sharing Program and the economic development projects funded by this program in terms of improving local communities’ attitudes toward lion conservation and the prevalent attitudes toward the Park itself.
The majority of the survey respondents had frequently seen and heard lions in their communities and was aware of human-lion conflict in their own community or in a nearby village. Their support for lion conservation was mainly due to the respondents’
perceived economic benefits from QENP’s foreign currency revenue and UWA’s Revenue Sharing Program. Despite community support for lion conservation, under the current noncompensated lion predation scenario, the majority of the surveyed community members would consider a lethal retaliatory action against the lions as “justified” or “acceptable.”
Prevalent attitudes of the respondents toward the Park officials and their general activities were positive. In terms of Park officials’ responsiveness to human-lion conflict, most survey respondents considered Park officials as mostly slow in responding to their call for emergency help and generally unresponsive to the community demand for the compensation of damages caused by Park lions.
Survey respondents were aware of the Park’s Community Conservation (CC) program. Among various CC policies, they particularly favored the Revenue Sharing Program whereby 20% of the Park revenue is shared among the communities within or neighboring the Park buffer villages. Such projects as adding two to three classrooms to overcrowded schools, building small health units, or supplying freshwater were very popular among the surveyed communities. The cost and execution of these projects were, however, disappointing to many respondents. The majority of the communities surveyed described these projects to be incomplete and generally of substandard quality. Many community leaders faulted their district and subcounty administrations for the inadequacy and mismanagement of these projects. Communities did not hold either UWA or the Park officials responsible for the low quality or the incomplete status of
these projects. But when they were asked to select the beneficial effects of the Park, many responded that the Park benefits were not fully visible in their communities.

▼ The exact ecological and economic role of lion
Panthera leo populations on small enclosed reserves is poorly
understood. The management and monitoring of such populations is
important to ensure their long-term survival. The prey use, range
use and habitat selection of an isolated lion population were
investigated. The study was conducted on a small (> 1000km2),
enclosed predator camp of Tswalu Kalahari Reserve, situated in the
Northern Cape Province of the Republic of South Africa. The prey
selection, prey preferences and prey biomass removal were
determined by using indirect and direct observations. Kill sites,
carcasses and scats were located by spoor tracking and
opportunistic observations and collated into a prey selection list.
The prey selection was used to determine any prey preferences and
the prey biomass removal by the lion population. The scats data was
corrected for relative prey biomass and compared to the kill data
and uncorrected scat data. 19 prey types were used, with the
gemsbok Oryx gazelle and blue wildebeest Connochaetes taurinus
being utilized most. The lion population had clear preferences for
specific small and large mammals which concurred with other studies
done on Kalahari lion behaviour. The prey biomass removal
(9.9kg/Lion feeding Unit/day) was higher than several other studies
done on lion consumption rates. The range use and habitat selection
were determined by using direct and indirect observations. The
minimum convex polygon method and kernel density estimates were
used to delineate the ranges of the lion population. The mean range
size of the Tswalu
lions (91 km2) was similar to those found for
lions in more mesic environments. The
lions also had clear habitat
preferences which depended on the habitat preferences of the prey
and the prey density. A population viability analysis, using VORTEX
9.72, was conducted. An Ecological capacity was determined and used
to model various environmental scenarios. The population was found
to be viable, but constant monitoring and updating are needed.
Management recommendations for the conservation of
lions and their
prey are provided.

▼ Methods used to estimate the prey consumption by
large carnivores include direct continuous observation, stomach
content analysis, carcass observations and scat analysis. Continual
observations are widely considered the best approach to estimate
large carnivore diets, with
lions (Panthera leo) being no
exception. Continual observation allows the recording of all prey
encounters and biases inherent in the other approaches are
minimised. However, continuous observations are not always
feasible, and in situations where animals cannot be observed at all
times, diets are often estimated from observed carcasses. This
often leads to an over-estimation of large kills in the estimated
diet. Alternative methods that are free of the constraints placed
on continuous observations are needed to provide data of a similar
quality to that obtained using these continuous observation bouts.
I employed a cluster follow up technique to locate lion kills from
remotely accessed Global Positioning System (GPS) data from
lions
in the Kruger National Park (KNP). I develop Generalized Linear
Models (GLMs) that increase the probability of locating kills at
GPS cluster events. By increasing the predictive ability of
detecting kills I show that this technique can be used to locate
kills in a more efficient manner than random searching of GPS
clusters, with further advantages in that multiple groups of
lions
can be monitored simultaneously. By incorporating this technique
into an adaptive research framework, the diet of
lions (and that of
other large carnivores) can be estimated. In addition, I show that
the spatial association between
lions at kill sites, while feeding
on carcasses, provides a further increase in the predictive ability
of kill site models. Lionesses were found to be considerably closer
together at the start of clusters associated with kills in
comparison to clusters where no kill was found. This pattern
remained consistent for both small and large kills. This proximity
approach could therefore be incorporated into the GLMs that are
developed to predict kill sites of large social carnivores. To
further reduce the bias (where small kills are often missed)
inherent in carcass observations, I combined scats and carcasses
collected from known times, locations and lion groups to construct
a temporal kill record for each group of
lions. By combining scats
and carcasses I estimate that at least 50% of the small prey items,
namely impala (Aepyceros melampus) and warthog (Phacochoerus
africanus) were missed when GPS clusters were investigated for
carcasses. Ultimately, I show that a combination of GPS cluster
investigations based on models developed using GPS movement data in
combination with lion proximity data, augmented with scats
collected at GPS clusters, could provide estimates of large
carnivore diets that begin to approach estimated diets obtained
through continuous monitoring. The resulting diet, estimated from
the GPS cluster approach in combination with scat collection,
indicated that the dominant prey item in the region was…

▼ O Cannes Lions Festival é o mais célebre festival mundial de publicidade, responsável por ditar tendências de mercado e consagrar profissionais e agências ganhadores de seus prêmios, os Leões. A área Films, para a qual se inscrevem as peças de audiovisual publicitário, é a fundadora do Festival e, até hoje, uma das mais cobiçadas. Ocorre, entretanto, que não há critérios publicizados ou concretos de avaliação das peças publicitárias e escolha das vencedoras, apenas um júri internacional de profissionais renomados com a orientação de premiar as propagandas mais criativas, ainda que tampouco seja estabelecido o que configura tal critério. Esta dissertação argumenta em direção a uma identidade de qualidade criativa reconhecida nos filmes vencedores do Festival, tendo como objetivo mapear e classificar as mudanças e permanências nas escolhas criativas das peças premiadas na área Films do Cannes Lions Festival entre 2002 e 2011, propondo uma visão do que é gerado pelo mercado e respaldado pela premiação. O principal critério adotado para distinguir as peças foi o relativo aos caminhos criativos escolhidos, definidos como de transgressão e/ou de ambiguidade, conceitos de Umberto Eco (1991 e 2001). O aporte teórico referente ao audiovisual é proveniente dos estudos de Jacques Aumont (1996) e Graeme Turner (1997), bem como o aprofundamento da pesquisa em publicidade se deu a partir das visões de Bigal (1999), Barreto (1982) e Domingos (2003). A submissão quantitativa de uma grande amostra de 131 comerciais vencedores a uma classificação com variáveis concernentes a audiovisual, criatividade e narrativa permitiu contabilizar os índices com maior e menor importância e constância na década e realizar cruzamentos a fim de perceber as tendências e relações entre as escolhas criativas para o audiovisual publicitário premiado ao longo do período.
The Cannes Lions Festival is the most prestigious international advertising festival, responsible for setting market trends and bringing fame to professionals and agencies that receive its Lions awards. The Films area, for which are subscribed the audiovisual ads, originated the festival and still is one of the most desired. On the other hand, there are no public or concrete criteria for the advertising pieces evaluation and selection, there is only a international jury featuring well-known professionals with the sole orientation to chose the most creative pieces, even if the definition of that criteria is not established. This dissertation argues in the aim to find an identity of the creative quality recognized in the films awarded in the festival, having as main objective to map and classify the changes and permanencies regarding creative choices among the prized pieces in the Films area of the Cannes Lions Festival from 2002 to 2011 proposing a vision about what is generated by the market and appreciated by the event. The main criteria adopted to distinguish the pieces was related to creative paths chosen, defined as transgression and/or ambiguity, concepts from Umberto Eco (1991 e…

▼ I describe the spatial and temporal distribution, abundance and habitat use of
Steller sea
lions (Eumetopias jubatus) in northern California between 2006 and 2011
obtained through shore and at-sea surveys and by tracking branded individuals.
Understanding Steller sea lion habitat use is critical in designing and implementing nearshore
management initiatives such as the Marine Life Protection Act (MPLA) initiative.
The MLPA initiative process began in northern California in 2009, affecting areas
offshore of Mendocino, Humboldt and Del Norte counties. Between the Oregon border
and Trinidad, California (Humboldt County) there is one rookery (Southwest Seal Rock)
and eight non-breeding haulouts. Steller sea
lions are more abundant on haulouts in
northern California during the late spring and summer months than during the rest of the
year. When Steller sea
lions are numerous in the area, their distribution is influenced by
age/sex class and breeding status. Adult males were seen more frequently on in-shore haulouts in both Trinidad and Crescent City, CA in late spring/early summer suggesting
that these haulouts serve as staging areas for breeding or near-breeding aged bulls (Otter
Rock mean = 7 ?? 1, Sea Lion Rock mean = 4 ?? 2, Castle Rock mean = 16 ?? 5). Breeding
Steller sea lion abundance peaked at Southwest Seal Rock during the June and July
pupping and breeding season (mean = 574 ?? 38). Presence of pups peaked at haulouts in
Trinidad the late summer/early fall suggesting that these sites serve as ???nurseries??? for
females and their dependent young (Otter Rock mean = 5 ?? 2, Turtle Rocks mean = 6.3 ??
3). Steller sea lion pups were branded on Southwest Seal Rock in 2002 and 2004 by
Oregon Department of Fish and Wildlife (ODFW) and National Marine Mammal Lab
(NMML) as part of a larger population dynamics study. Females from these cohorts are
now actively breeding in northern California, while fewer branded males have come back
to the rookery during breeding season (49 females vs. 18 males). Resights of branded
females were more common than males. Of the 62 branded animals that were seen in
more than one year during the study period, 73% were female. Male Steller sea
lions
tended to be resighted farther from the natal site than females. Steller sea
lions
frequented many haulouts during a single year and females, in particular, showed fidelity
to the northern California and southern Oregon near shore waters.

▼ Interaction between species through competition is one of the principle processes shaping the structure of ecological communities. Competition can have significant effects on the behavior, distribution, and ultimately the population dynamics of species, particularly when the animals utilize similar resources. Extensive diet overlap between large African carnivores is associated with high levels of competition which is particularly evident in the interactions between
lions (Panthera leo), spotted hyenas (Crocuta crocuta) and African wild dogs (Lycaon pictus). Using GPS data collected from sightings of large carnivores in Hluhluwe-iMfolozi Park, South Africa, I tested the hypothesis that wild dogs??? space utilization was influenced by other large carnivores. I found that wild dogs had different responses to their two main competitors. They avoided
lions, particularly during denning seasons, through a combination of spatial and temporal avoidance. However, the dogs did not alter space use relative to hyenas, likely because pack sizes were large enough to defend their kills adequately without the necessary effort of avoidance. Information from this study is important for managing current carnivore populations, especially as reintroductions and translocations are essential tools used for the survival of endangered African wild dogs.
