▼ The demand by ecotourism for easily accessible wildlife encounters has increased the need for regulations to minimise negative effects of tourism on towards marine mammals. High levels of human interaction could have serious consequences for recovering populations of New Zealand fur seals (Arctocephalus forsteri). By monitoring behavioural shifts in reactions to human disturbance, the aim of this study was to determine how disturbance by tourism is affecting the behaviour of the New Zealand fur seals. Fur seal breeding colonies, haul-outs, and a pup nursery were studied on the South Island to determine the level of disturbance. Data collected in this study can be used towards improving monitoring regimes to mitigate negative effects of anthropogenic disturbance. I first used behavioural observations to assess a seal’s behaviour in response to different types of tourist activities. Next, I examined changes in New Zealand fur seal behaviour as a result of visits to colonies by tourist boats. To quantify the response of fur seals to tourist boats, experimental boat approaches were conducted using a before, during, and after instantaneous scan sampling method at two breeding colonies (one with high vessel traffic and one with none). Impact of noise was also investigated using a loud speaker to mimic local harbour tours. Lastly, behavioural observations on seal pups at a nursery were conducted comparing pup behaviour in the presence and absence of tourism along with variable intensities of tourist behaviour. My observations suggest that seal behaviour was significantly different between sites with and without tourist visits. The type of tourism had a significant effect on the behavioural state of seals, with animals more active when there were people walking in the colonies. There were also signs of habituation in some of the study colonies. Since each colony varied in the type of tourism it experienced, it is possible that it is not only the level of tourism that is important but also the type of tourism that has a significant role in eliciting short-term behavioural shifts. Observations from a tour boat revealed an increase in the percentage of seals reacting when vessels were close to the shore. This distance effect was overridden and reactions were greater, however, when tours included commentary via an external speaker. The effects of both distance and noises were significantly different between colonies with high and low levels of tourist visits. Due to the overlap of peak tourist visits with fur seal breeding season, these animals are at their most vulnerable when companies are in peak operation. Finally, as with adults, pup behaviour was also significantly affected by tourism presence. Periods of inactivity and awareness increased in the presence of tourists, which is indicative of disruption of “play” and movement towards more vigilant behaviour. Despite the significant effects of tourist visits I found in this study, there was large variation in the degree of responses in different populations of the fur seal.…

▼ A recognition system is required between pinniped mothers and pups. For otariids this is especially important since females frequently leave their pups for foraging and must reunite on return. Pups must deal with these fasting periods during maternal absence and consequently may attempt to obtain allomaternal care from unrelated females. This research on the New Zealand fur seal (Arctocephalus forsteri) at Ohau Point, Kaikoura, New Zealand, quantified mother-pup recognition behaviour during reunions, individuality of pup calls used by mothers to recognise their pup, and the occurrence of allosuckling as a possible recognition error by females and as a strategy employed by pups to gain allomaternal care during their mothers' absence. A combination of behavioural observations, morphometry, VHF radio telemetry, acoustics and DNA genotyping were employed to study these topics. Postpartum interaction behaviours between mothers and pups appeared to facilitate development of an efficient mother-pup recognition system, involving mainly vocal and olfactory cues that were utilised during reunions. Greater selective pressure on pups to reunite resulted in an asymmetry of searching behaviour between females and pups during reunions. The vocalisations of pups were stereotypic, especially those features of the fundamental frequency and frequency of the lowest harmonic, which are likely to facilitate recognition of a pup by their mother. Pups attempted to steal milk from unrelated females more often during maternal absence and appeared to modify the intra-individual variation pattern of a feature of their vocal signatures over this period, which may assist attempts at allosuckling under nutritional stress. Fostering was demonstrated to occur despite costs to filial pups and possible costs to female reproductive success and may be attributed to development of erroneous recognition between females and non filial pups, or kin selection. This study provides a valuable contribution to the knowledge of recognition systems between pinniped mothers and pups, of alternative pup strategies under nutritional stress and of the rare occurrence of fostering in otariid pinnipeds.

▼ The New Zealand fur seal (Arctocephalus forsteri) and the long-finned pilot whale (Globicephala melas) represent two phylogenetically unrelated species that inhabit the same environment and utilise similar prey. The stomach anatomy of the New Zealand fur seal and the long-finned pilot whale has not been well studied. Because of the scarcity of published information on these two species, this study was undertaken to identify differences and similarities between the two species. A literature review considers work on the stomach anatomy of other marine mammal species to allow for comparisons and parallels to be made. The stomachs of 10 New Zealand fur seal and 7 long-finned pilot whale cadavers were examined macroscopically and microscopically. The single chambered stomach of the New Zealand fur seal was similar to that of other pinnipeds. The stomach was J-shaped: with an elongate proper-gastric region, a sharply bent incisura angularis and narrow pyloric portion that extended cranially to a well-developed pyloric sphincter. The lining of the empty stomach was arranged into well-defined rugae that were sparser and less tortuous beyond the pyloric antrum. The microscopic anatomy of the stomach wall was similar to the typical mammalian carnivore plan. However, some differences were evident, including a narrower cardiac zone, and longer proper-gastric glands because of the numerous mucous neck and parietal cells. The multi-chambered stomach of the long-finned pilot whale was similar to that of other cetaceans. The stomach consisted of three chambers: a muscular, pear-shaped forechamber followed by a bulbous proper-gastric chamber and a thin walled pyloric chamber divided into a channel-like cranial portion that was further subdivided by a transverse septum and a tubular caudal portion. The orifices between chambers and the chambers themselves progressively decreased in size. The proper-gastric and pyloric chambers are comparable to those zones of the typical mammalian stomach. However some differences were evident, including the abrupt changes in mucosa between chambers, lack of a cardiac zone, a forechamber lined by non-glandular epithelium and a thicker stomach wall. It is concluded that the stomachs of the New Zealand fur seal and the long-finned pilot whale are macroscopically different but microscopically similar. The stomachs are similar to those of other pinnipeds and cetaceans, respectively. Therefore, anatomical variations are likely to be phylogenetic in origin as otariids are believed to be derived from bear-like carnivorous ancestors whereas cetaceans are from the ancestors of ruminants.

▼ Colony dynamics, maternal investment, and indicators of health were investigated for the New Zealand fur seal (Arctocephalus forsteri) over four austral summers, 2001- 2005. Effort was focused at the Ohau Point seal colony, north of Kaikoura. Two colonies at Banks Peninsula were included for comparisons of colony growth and pup condition. A range of other colonies were also included for making comparisons about colony dynamics and health indices. Colony dynamics were investigated through mark-recapture estimates of pup production and daily census of all individuals at the Ohau Point colony. Maternal attendance patterns were observed through behavioural observations of known females (n = 120), the use of VHF radio transmitters (n = 33), and female mass and body condition estimates (n = 51). Maternal investment was also investigated through longitudinal sampling of pup mass and growth rates. Parameters used to indicate colony health were: body condition, growth, presence of parasites, and the levels and common causes of mortality. The influence of parasites on pup growth was tested using treatment of selected pups with Ivermectin anti-helmentic medication, and mortality in the region was investigated through reports of dead individuals, and post mortems of those found fresh. The Ohau Point colony is in an exponential state of growth, and pup mass and condition was higher and responded to changes in environmental variables differently than at the Banks Peninsula colonies. Lactation lengths were consistently longer at Ohau Point than is typically reported for the species (323-355 days vs. 285 days). Maternal investment strategies were indicative of a close, reliable food source, and showed flexibility between years through extension of foraging trip durations and the increased use of overnight foraging trips. Individual strategies did not significantly influence pup growth. However, increased maternal condition and the ability to respond to inter-annual changes in resource availability resulted in accelerated pup growth even during an El Niño event. The incidence of pups with intestinal parasites was low at Ohau Point, and the average mass of treated and non-treated pups did not differ. Pup mortality in the region was low (3% to 50 days old), however, mortality of older pups was greatly influenced by the proximity of humans, with 2/3 of pup mortality observed between the age of 50 days and weaning being caused by car collisions. The results suggest that population dynamics and maternal investment in the region are greatly influenced by local variables, notably the presence of an accessible food source within close proximity to the colony. Various indicators of health reflect a growing colony in good condition, and the presence of a reliable food source may influence the maximum density and carrying capacity the colony is able to sustain. However, some concerns are raised about the influence of human interactions in the region, and how this may affect mortality and colony dynamics in…

▼ Contemporary resource use on Indigenous lands is not often well understood by the general public. In particular, there is a perception that “traditional” and commercial resource use are mutually exclusive, and therefore there is often an assumption that Indigenous communities are abandoning their traditional economy when they participate in the commercial sector of the larger regional economy. This perceived tension between traditional and commercial resource use is caused in part by a limited understanding of the participation of Indigenous peoples in commercial industries historically and the subsequent process of the commercialization of some aspects of Indigenous peoples’ pre-contact economies. This dissertation examines the seasonal cycle of activities and the patterns of consumption and production of the Indigenous peoples who participated in the fur trade at Ile a la Crosse in northwestern Saskatchewan and the whaling industry at the Otakou shore station in southern New Zealand. A systematic analysis of the daily journals and accounting records kept by company employees in these two regions demonstrate that participation in these industries allowed the Indigenous economies to be transformed from pre-contact times. While this participation did not completely subsume the Indigenous economies, the changes that were made created a need for the Indigenous people to continue accessing the European-style goods that had been incorporated into their livelihoods, a need that was exacerbated as local resources declined as a result of over-use. Thus, there is a need to re-conceptualize what is generally thought of as the “traditional economy.” The traditional economy in contemporary Indigenous communities is often perceived as an Indigenous approach to resource use that has changed little, except perhaps in the technology used, from pre-contact times. This dissertation, however, clearly demonstrates that participation in commercial industries historically encouraged the adaptation of Indigenous economies in response to changing opportunities and circumstances. It becomes clear then that the so-called “traditional economy” of today, is an Indigenous economy that has already been shaped and influenced by participation in historical commercial economies. Understanding the adaptability of Indigenous economies has important implications for economic development initiatives in Indigenous communities today.

▼ New Zealand fur seals (NZFS, Arctocephalus forsteri) are a relatively common feature on the rocky coasts of Southern Australia and New Zealand’s North, South, and subantarctic Islands. Several previous studies (e.g. Lento et al. 1997, Wynen 2001, Robertson and Gemmell 2005) have endeavoured to describe the population structure of NZFS, and have been unable to resolve distinct genetic differentiation among breeding colonies. However, it was unclear whether this could be attributed to an absence of structure in the species, or simply to a lack of discriminatory power provided by the molecular markers available at the time. In this study, we utilised a large and highly variable dataset of single nucleotide polymorphisms (SNPs) to thoroughly investigate population genetic trends, and to identify and describe new sources of genetic variation. We incorporated a total of 253 NZFS samples (167 from eight breeding colonies, 86 from fisheries bycatch) into our analyses. Adhering to the sequencing preparation protocol Genotyping-by-sequencing (GBS, Elshire et al. 2011), we digested DNA samples with the restriction enzyme Pst1. This effectively resulted in a reduction of genomic complexity, allowing for efficient identification of sites of variation at cut site loci. Post-sequencing bioinformatics processing (Stacks, Catchen et al. 2011) was implemented to produce a catalogue of 473,338 monomorphic and polymorphic loci for further analyses. We present a novel approach for the discovery and statistical validation of male-specific (Y-chromosome) loci in GBS datasets. Using a sex-specific locus threshold (SSLT) and a significant sex-assignment threshold (SSAT), we identified male-specific loci (monomorphic and polymorphic) within our dataset. We then screened for those loci within individuals of unknown sex in our bycatch sample group, and assigned sex to those individuals in silico. A significant bias toward males with the bycatch sample group was identified across all regions (68.6% – 80.2%, p < 0.001), which is consistent with previous observations on the species’ foraging behaviour. In addition, we developed a small panel of sex-specific PCR primers that can be used to ascertain the sex of unknown individuals in future studies. We employed a robust dataset of 22,192 neutral SNPs to investigate variation within and between NZFS subpopulations. While our conclusions were consistent with previous observations of relatively low population differentiation (0.65% – 0.85% variation explained by regional differences), we identified distinct similarities among West Coast colonies and Southern East Coast colonies. Northern East Coast colonies appear to be sites of genetic confluence, though further research will be required to verify these signatures. A weak, but significant (p = 0.01) isolation-by-distance pattern was identified among the eight breeding colonies studied, indicating a degree of previously overlooked, fine-scale population structure in this species. Using a new toolkit to examine genetic variation in… Advisors/Committee Members: Gemmell, Neil (advisor).

▼ Assessment of trophic interactions between increasing populations of New Zealand fur seals (Arctocephalus forsteri) and fisheries in southern Australia is limited due to a lack of species specific demographic data and an understanding of the factors influencing population growth. To establish species specific demographic parameters a cross-sectional sample of New Zealand fur seal females (330) and males (100) were caught and individually-marked on Kangaroo Island, South Australia between 2000 and 2003. The seals were aged through examination of a postcanine tooth, which was removed from each animal to investigate age-specific life-history parameters. Annual formation of cementum layers was confirmed and accuracy in age estimation was determined by examination of teeth removed from individuals of known-age. Indirect methods of assessing reproductive maturity based on mammary teat characteristics indicated that females first gave birth between 4-8 years of age, with an average age at reproductive maturity of 5 years. Among reproductively mature females, age-specific reproductive rates increased rapidly between 4-7 years of age, reaching maximum rates of 70-81% between 8-13 years, and gradually decreased in older females. No females older than 22 years were recorded to pup. Age of first territory tenure in males ranged from 8-10 years. The oldest female and male were 25 and 19 years old, respectively. Post-weaning growth in females was monophasic, characterised by high growth rates in length and mass during the juvenile growth stage, followed by a gradual decline in growth rates after reproductive maturity. In contrast, growth in males was biphasic and displayed a secondary growth spurt in both length and mass, which coincided with sexual and social maturation, followed by a rapid decline in growth rates. Age-specific survival rates were high (0.823-0.953) among prime-age females (8-13 yrs of age) and declined in older females. Relative change in annual pup production was strongly correlated with reproductive rates of prime-age females and adult female survival between breeding seasons.

▼ Worldwide expansion of marine mammal tourism over recent decades has raised international concerns in terms of the effects of these tourism practices on the species they target. Moreover, the growth and success of the industry have often outpaced conservation planning, including in New Zealand. To illustrate, tour vessels have been operating for ca. 25 years in the Bay of Plenty (BOP), situated on the east coast of North Island, New Zealand. By 2010, a total of eight permits had been granted across the region. However, development of this local industry occurred without any baseline data on species occurrence, distribution, habitat use or behaviour. This study sought to assess the historical occurrence of the marine mammal species off the BOP and determine their spatial and temporal distribution. Current distribution, density and group dynamics were examined for common dolphins (Delphinus sp.) and New Zealand fur seals (Arctocephalus forsteri), the two most frequently encountered species in the BOP and therefore, the primarily targeted species by tour operators. The extent of anthropogenic interactions with common dolphins was investigated and their effects on dolphin behaviour examined. The number of common dolphin individuals closely interacting with tour vessels was estimated and dolphin-vessel interactions were quantified to assess repetitive encounters. In the absence of previously undertaken systematic dedicated surveys, the present study investigated the historical spatial and temporal occurrence of dolphins, whales and pinnipeds in the BOP region. The examination of opportunistic data, collected between December 2000 and November 2010 via various platforms of opportunity including but not limited to tour vessels, identified fourteen species of dolphins, whales and pinnipeds occurring in the region. Confidence criteria in successful species identification were assigned based on observer expertise, diagnostic features of reported species and percentage of records reported by observer type. Common dolphins were the most frequently encountered species, followed by killer whales (Orcinus orca), bottlenose dolphins (Tursiops truncatus) and New Zealand fur seals, other species being infrequently encountered. A detailed examination of common dolphin habitat use revealed discrepancies with previous findings (e.g. higher use of shallower waters), possibly explained by inherent biases to the opportunistic dataset. Dedicated surveys, conducted between November 2010 and May 2013, investigated the current distribution, density and habitat use of common dolphins and New Zealand fur seals. Both species exhibited a strong seasonality with contrasting occurrence in summer and autumn for common dolphins and in winter and spring for fur seals. Dolphin seasonality is suggested to be linked to movements into deeper offshore waters and/or potentially to neighbouring regions (i.e. the Hauraki Gulf) and most likely related to foraging opportunities. Fur seal seasonality suggests that the western BOP supports a non-breeding colony…

▼ The Cape fur seal Arctocephalus pusillus pusillus colony at the Robberg Peninsula, Plettenberg Bay, on the south-east coast of South Africa, was driven to extirpation by indiscriminate harvesting by the late 1800s and seals only began to recolonise this site in the 1990s. This study describes the recolonisation process from 2000 to 2009, exploring within- and between-year variation in the number of seals using the site. Numbers increased over the study period from less than 300 animals to over 3 100. Year and month were important in explaining variability in seal counts, whereas sea condition, time of day and lunar phase had minimal explanatory power. Within-year variation in seal counts decreased during the study period, which may indicate an increasing proportion of resident (as opposed to transient) seals in the colony. However, the colony is currently still in a transition phase with a low ratio of breeding to non-breeding animals and low numbers of pups born on the colony (currently still < 100 per year). The influx of seals to the Robberg area may be associated with an increase in prey availability in the area. The relative protection afforded by the Nature Reserve status of the Robberg Peninsula and the existence of a Marine Protected Area adjacent to it are likely to contribute to the growth of this colony. However, human interference associated with fishing and/or ecotourism on the Peninsula may prevent the colony from developing into a breeding colony. Faecal (scat) sampling was employed to study the diet of this increasing seal population at Robberg. Species composition and size of prey were determined, temporal variation in the diet was explored, and the potential for competition between seals and the fisheries around Plettenberg Bay was investigated. Of the 445 scats collected, 90 % contained hard prey remains. These comprised of 3 127 identified otoliths representing 15 teleost prey species, 25 cephalopod beaks representing three 6 species and three feathers representing two bird species. The seals' most important prey species in terms of numerical abundance and frequency of occurrence in the diet were anchovy, sardine, horse mackerel, sand tongue-fish and shallow-water hake (in decreasing order of importance). The proportion of anchovy in the diet increased during the study period, while sardine decreased. Sardine was the only species that increased significantly in the diet during the upwelling season. Little evidence was found of direct competition between seals and linefisheries in Plettenberg Bay, both in terms of prey species composition and quantities consumed. Scat sampling in seals holds promise as a method to track long-term changes in prey species availability. The conservation and management of this colony are discussed in light of the research findings.

▼ Knowledge of the habitat use and foraging ecology of animals in space and time is fundamental to understanding the structure and function of their ecosystems, inter-relationships with earth and climate systems, and to inform management and conservation. The examination of relationships across ecological levels (individuals, populations, species) can reveal the effects of the intrinsic characteristics of individuals and extrinsic environmental factors, and contributes to a broader understanding of an animal’s biology. This thesis examines the foraging behaviours, habitat use and drivers of these for female Antarctic fur seals (Arctocephalus gazella) from three Southern Ocean colonies during the poorly studied austral winter, from the individual to the species level. The at-sea winter distribution of Antarctic fur seals from Marion Island, Bird Island and Cape Shirreff was quantified over six years (2008-13) using archival global location sensing (GLS) loggers, while time-depth recorders were used to record diving behaviour at Marion Island (2012 and 2013). Specifically, this thesis aims to (1) ascertain the degree of foraging site fidelity of seals, (2) use diving behaviour to identify foraging strategies and associated costs and benefits, (3) identify important winter foraging habitats of populations and their associated environmental characteristics and (4) quantify recent decadal changes to winter habitat and temporal variability in habitat use to facilitate assessment of the degree of overlap with Southern Ocean management areas and fisheries. (1) Data from Marion and Bird Island animals was used to assess individual fidelity to oceanic foraging sites. Site fidelity was examined at two scales: within and between years. Within-year site fidelity was typically weak, indicating that successive foraging trips over the winter target different regions in response to seasonal environmental changes. Conversely, between-year fidelity to foraging regions was strong for the majority of animals (>50% of the annual home range re-used), who returned to individually unique foraging grounds over multiple years. The major oceanographic parameter typifying areas of re-use was a high long-term (multi-decadal) variance in sea surface temperature, which is likely associated with elevated productivity and increased energy intake over the individual’s lifetime. These findings show that foraging strategies not only vary between individuals, but also can persist over the long-term. (2) Diving behaviour and fine-scale habitat use were examined during the post-breeding migrations of Antarctic fur seals by combining vertical and horizontal movement data. The relationship between movement responses across horizontal and vertical dimensions was assessed. A broken-stick approach, novel for otariid seals, quantified within-dive foraging effort and identified two distinct foraging strategies that presently co-exist in the Marion Island population: (i) remain north of the Polar Front close to the colony, or (ii) transit south of the Polar…

▼ Several neuronal systems contribute to the generation and maintenance of sleep and waking. Knowledge pertaining to the neurotransmitters involved in sleep-wake regulation has been derived primarily from species that display bilaterally symmetric EEG states (e.g. cats, dogs, rats, and mice). However, these studies do not indicate which aspects of sleep these neurotransmitters are specifically linked to. Fur seals display both bilateral (BSWS) and asymmetrical sleep slow-wave sleep (ASWS); this unusual sleeping pattern provides a unique opportunity to determine which of the many physiological and neurochemical changes seen bilaterally in terrestrial mammals are linked to the cortical EEG changes and which may be linked to the motor and/or autonomic aspects of sleep. In studying this remarkable feature of the fur seal, we can dissociate the thalamocortical EEG activity in each hemisphere from aspects of behavioural state and study each independently as they relate to neurotransmitter release. The overall aim of my thesis was to examine, simultaneously in both hemispheres, the release of key neurotransmitters in the cortex across the sleep-wake cycle in the northern fur seal, and to specifically compare levels during BSWS and ASWS. In vivo microdialysis and high-performance liquid chromatography were used to monitor the release of neurotransmitters during polygraphically defined states. Neurotransmitters previously thought to contribute equally to the waking state, actually behave quite differently in a brain that is half awake and half asleep. Cortical acetylcholine (ACh) release was highly lateralized during ASWS, with greater release in the activated hemisphere, whereas cortical serotonin (5-HT), noradrenaline (NA), and histamine (HA) were symmetrically released during ASWS. Of the arousal systems studied so far, only ACh is involved in the lateralized cortical EEG activation manifested in asymmetric sleep. Bilaterally symmetric levels of the monoaminergic transmitters studied to date are compatible with interhemispheric EEG asymmetry. Findings suggest distinct functional roles for ACh, 5-HT, NA, and HA in the regulation of wakefulness, with respect to cortical activation and behavioural arousal.

▼ As part of a health survey of New Zealand sea lions (Phocarctos hookeri) on Enderby Island, Auckland Islands (50°30’S, 166°17’E), neonatal mortality was continuously monitored at the Sandy Bay Beach rookery, from 1998/1999 to 2004/2005. The primary causes of death were categorised as trauma (35%), bacterial (24%) and hookworm (13%) infections, starvation (13%) and stillbirth (4%). During the 2001/2002 and 2002/2003 breeding seasons, bacterial epidemics caused by Klebsiella pneumoniae increased mortality by three times the mean in non-epidemic years. Uncinaria spp. from New Zealand sea lion (NZSL) pups was described for the first time using morphometric criteria. It differed from the two species already described in pinnipeds, Uncinaria lucasi and Uncinaria hamiltoni, suggesting the existence of a different morphotype in NZSLs. A study on the epidemiology of hookworm infection showed that all pups up to at least three months of age harboured adult hookworms in their intestines and transmammary transmission was identified as the route of infection of NZSL pups. Uncinariosis as a primary cause of mortality was generally associated with anaemia, haemorrhagic enteritis and frank blood in the lumen. The relationship between hookworm burden and clinical disease could not be clearly established. The 2001/2002 and 2002/2003 bacterial epidemics at Sandy Bay Beach rookery were caused by a clonal strain of Klebsiella pneumoniae as verified by pulse-field gel electrophoresis and antimicrobial testing. Suppurative arthritis was the most common post-mortem diagnosis during the two epidemic seasons. Internal lesions were consistent with septicaemia, which explained the wide range of organs from which the pathogen was grown in pure culture. A serological test investigating the exposure of NZSLs to Klebsiella spp. showed that the large majority of pups up to two months of age did not have any anti-Klebsiella antibodies, even after the epidemics, but that almost all the adults were seropositive. In addition, passive immunoglobulin (Ig) transfer from lactating females to neonates was examined by measuring IgG levels in pups and was very low compared to terrestrial mammals although similar to other pinniped neonates.

O presente estudo foi realizado com o objetivo de identificar genomas de vírus em fezes de lobos marinhos sul-americanos (Arctocephalus australis) e lobos marinhos subantárticos (Arctocephalus tropicalis), duas espécies de pinípedes encontradas no litoral do Rio Grande do Sul. Embora já existam estudos sobre esse tema em outras espécies de pinípedes, nas espécies aqui trabalhadas o tema permanece inexplorado. Amostras de fezes foram obtidas de vinte e um lobos marinhos sul-americanos e dois lobos marinhos subantárticos encontrados no litoral rio-grandense com indícios de morte recente, durante os meses de Junho e Julho de 2012. Através de técnicas de PCR e sequenciamento buscou-se identificar genomas de circovírus, adenovírus, morbilivírus, calicivírus e coronavírus. A amplificação de um fragmento do gene rep permitiu a identificação de prováveis circovírus em amostras de seis lobos marinhos sul-americanos. Análises filogenéticas revelaram que três dos seis segmentos são sugestivos de prováveis membros do gênero Cyclovirus. Os genes amplificados de outras duas amostras provavelmente correspondem a membros do gênero Circovirus. Uma das amostras deu origem a um segmento gênico que não apresenta similaridade com nenhum gênero já proposto da família Circoviridae. Além disso, foi possível detectar também fragmentos de genomas de adenovírus em duas amostras; estes apresentam alto grau de similaridade de nucleotídeos com amostras de adenovírus humano tipo C. Nenhum fragmento genômico indicativo da presença de morbilivírus, calicivírus ou coronavírus foi encontrado. Os resultados aqui obtidos sugerem a presença de circovírus, ciclovírus e adenovírus em populações de lobos marinhos encontrados na costa do Rio Grande do Sul. Estes achados reforçam a necessidade da ampliação do conhecimento a respeito da ocorrência de infecções virais nestas espécies.

This study was conducted with the objective of identifying genomes of viruses in feces of south american fur seals (Arctocephalus australis) and subantarctic fur seals (Arctocephalus tropicalis), two species of pinnipeds found on the coast of Rio Grande do Sul. Although there are studies about this topic in other species of pinnipeds, it remains unexplored in these two species. Stool samples were obtained from twenty-one south american fur seals and two subantarctic fur seals found in Rio Grande do Sul coastline with evidences of recent death, during the months of June and July 2012. PCR and sequencing techniques were utilized to identify circovirus, adenovirus, morbillivirus, calicivirus and coronavirus genomes. The amplification of a rep gene fragment allowed the identification of supposed circoviruses in samples of six south american fur seals. Phylogenetic analysis revealed that three of the six segments are suggestive of probable members of the genus Cyclovirus. The amplified genes from two other samples probably correspond to members of the genus Circovirus.

O lobo-marinho-sul-americano (Arctocephalus australis) membro da Ordem Carnivora, é comumente visto nos períodos de outono e inverno na costa brasileira do Rio Grande do Sul até o Rio de Janeiro, porém, sem colônias reprodutivas estabelecidas. A espécie pertence ao grupo dos pinípedes, carnívoros com membros em forma de nadadeiras que vivem em ambiente aquático e terrestre. Estudos sobre a morfologia da pele em pinípedes são raros e antigos, destes procederam muitos relatos divergentes, em virtude da colheita da pele sem referências anatômicas. O objetivo desta pesquisa foi descrever o sistema tegumentar da espécie Arctocephalus australis, utilizando animais que vieram a óbito por causas naturais de uma colônia reprodutiva do Uruguai. As áreas corporais colhidas dorso-ventralmente foram identificadas anatomicamente. Essas regiões foram examinadas por microscopia óptica, segundo critérios histológicos, histomorfométricos, histoquímicos e imuno-histoquímicos nas diferentes estruturas que constituem o sistema tegumentar. A pele do Arctocephalus australis apresentou diferenças entre as regiões de epiderme delgada e espessa. A epiderme delgada apresentou maior quantidade de pêlos do que a epiderme espessa, a qual em algumas regiões era destituída destes. Como os demais mamíferos, a pele do lobo-marinho-sul-americano apresentou glândulas sebáceas, glândulas sudoríparas apócrinas e merócrinas. As nadadeiras apresentaram o maior número de especializações entre as regiões do corpo estudadas, especialmente vinculadas à termorregulação, como o maior volume de glândulas sudoríparas e secções vasculares. Esta pesquisa apontou os aspectos morfofuncionais relacionados à biologia da espécie em ambientes distintos, e esclareceu alguns dados controversos na literatura sobre o sistema tegumentar em pinípedes.

The South American fur seal (Arctocephalus australis) members of the Order Carnivora is usually seen during the autumn and winter season in the Brazilian coast from Rio Grande do Sul to Rio de Janeiro, however, there are no reports of reproductive colonies established. The species belongs to the group of pinnipeds, carnivorous with limbs fin-shaped that inhabits both terrestrial and aquatic environments. Studies of the skin morphology are rare and ancient; these studies have arisen many divergent reports, due to sampling of the skin without anatomical references. The purpose of this research was to describe the integumentary system of the species Arctocephalus australis, using animals that came to death by natural cases from reproductive colonies from Uruguay. The body dorsal and ventral regions were identified anatomically. These regions were examined by light microscopy, according to the histological, histomophometric, histochemical and immunohistochemical criteria in the different structures constituting the integumentary system. The skin of the Arctocephalus australis showed differences between the thin and thick epidermis. The thin epidermis showed larger amount of hair follicles than the thicker epidermis, which in some…

▼ Dyer Island is thought to host one of the most abundant populations of white sharks on the planet; this is often credited to the large (55 – 60,000) Cape fur seal colony at Geyser Rock. Yet relatively little work has ever been produced from the area. This may be attributed to the harshness in its location as a study site, exposed to wind and swell from west to east which limits research periods. This study accounts for over 220 hrs of manual tracking at Dyer Island with a further 68 added from the inshore shallow areas of the bay. Sharks focused their movements and habitat use to reefs or channels that allowed access to Cape fur seals. Movement- Based Kernel Estimates (MKDE) were used to compute home range estimates for shark movements through and around the heterogeneous structures of Dyer Island and Geyser Rock. Inshore two core areas were revealed, one being the major reef system at Joubertsdam and the other at a kelp reef where the tracked shark had fed on a Cape fur seal. At Dyer Island one core area was identified in a narrow channel, ‘Shark Alley’, here a second tracked shark foraged for entire days within meters of rafting Cape fur seals. Rate of Movement (ROM) and Linearity (LI) of tracks were low during daytime and movements were focused around areas such as Shark Alley or other areas close to the seal colony before moving into deeper water or distant reefs with higher rates of ROM and LI at night. If moonlight was strong foraging would take place to the south of Geyser Rock but with higher ROM and LI than observed during the day. Foraging patterns in this study contrast studies from other sites in South Africa and home range and activity areas were comparatively much smaller than observed in Mossel Bay. It has been established that several known white sharks forage at Dyer Island and the other studied aggregation sites, such differences in foraging would suggest that they are able to adapt their foraging behaviour to suit the environment they are in; making them site specific in their foraging ecology. Both satellite and acoustic telemetry are revealing aggregation hotspots of white sharks in South Africa. It is important that such information is used to assist the recovery of the species which has been protected since 1991, yet is rarely considered in planning of coastal developments.

▼ The Australian fur seal (Arctocephalus pusillus doriferus) population has displayed a relatively slow rate of recovery since being hunted by commercial sealers during the early 19th century. Despite this, population abundance doubled in the past 2 – 3 decades, indicating that the population growth rate has recently increased. Yet, the factors influencing the population’s dynamics are poorly understood, primarily because basic demographic rates are unknown. Female age, survival, fecundity, breeding and physiology were studied at Kanowna Island, Bass Strait, Australia, between 2003 – 2006 by conducting censuses and captures (n = 294). Mark-recapture estimates of pup production were used to validate direct pup counts, allowing a 9-year dataset to be used for calculation of the population growth rate (2.2% p.a.) and investigation of environmental influences on reproductive success. Annual pup production (x = 3108) was synchronous, with 90% of births occurring within 28 days of the median birth date of 23 November. Births occurred earlier in years when pup production and female body condition were high and these factors were correlated with local oceanographic indicators, suggesting that reproductive success is constrained by environmentally-mediated nutritional stress. Pregnancy was assessed by blood plasma progesterone radioimmunoassay and the pupping status of the same females was observed during breeding season. Despite high mid-gestation pregnancy rates (x = 84%), the birth rate was lower than in other fur seals (x = 53%), suggesting that late-term abortion is common. Lactating females were less likely to pup, indicating that nutrition may be insufficient to support concurrent lactation and gestation. Age and morphometric data were used to construct body growth, age structure and survivorship models. Adult female survival rates were similar to those of other fur seals (x = 88.5%). A life table was constructed and its age-specific survival and fecundity rates used in a Leslie-matrix model to project the population growth rate (2.2% p.a.) and determine the relative influence of each parameter. The abundance of female non-pups was 6 times greater than that of female pups, which is approximately 50% higher than previous conversion factors used to extrapolate population abundance from pup censuses in Australian fur seals. However, if the non-pup sex ratios of other otariids are considered, the pup:population conversion factor is 4.5. Compared to a study performed before the recent population increase, the modern population displays similar body growth and fecundity rates but higher survival rates. This suggests that recent population growth resulted from a relaxation of hunting and/or predation mortality rather than from increased food availability. The low population growth rate is attributed to a low birth rate associated with nutritional…

▼ Data collected from Pribilof far seals, Callorhinus ursinus, on land (1911-89) and at sea (1958-74) are analyzed to establish biological relationships and distinguish ecological patterns that are relevant to understanding and managing northern fur seal populations. The thesis follows the development of the fur seal from conception and birth through to sexual maturity and finally to a synthesis of the earlier material in terms of population regulation, management, and reasons for the decline of the Pribilof herd. Growth curves show that male fetuses grow faster and larger than female fetuses, and that fetal size is influenced by the age, size, and reproductive history of the mother. Juvenile and adult fur seals experience pronounced seasonal increases and decreases in body length and mass. Rapid gains in mass and growth occur during a brief 1-3 month period as the population migrates through the coastal waters of northern British Columbia and Alaska on its way to the Pribilof Islands. Body mass is gradually lost during the rest of the year while fasting on land and wintering along the coasts of Washington, Oregon, and California. The timing of migration and pupping is highly synchronized from year to year and may be related to the effect of climatic conditions on pup survival during the breeding season. Predictions from a thermal budget developed for pups and the results of a seasonal decomposition of weather patterns on the Pribilof Islands show that the synchronism of births in early July corresponds to the start of three months of conditions that are optimal for growth and survival of pups. Long term fluctuations are noted in pup mass and subadult growth rates which may be related to underlying, large scale natural changes in prey abundance. Changes in the physiological condition (body growth) and vital rates (survival and reproduction) are analyzed for the period 1911-89 as the population increased and decreased. Few density dependent relationships could be demonstrated. Two hypotheses concerning the current decline of the Pribilof population are reviewed and a new, third hypothesis is proposed. The thesis also examines biases in data collection related to the effects of tagging and the handling of fur seals and outlines some directions for future research.
