▼ 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 (8-13yrs 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.

▼ 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.…

▼ At Cape Gantheaume, Kangaroo Island (South Australia), adult male, lactating female and juvenile New Zealand (NZ) and Australian fur seals regularly return to the same colony, creating the potential for intra- and inter-specific foraging competition in nearby waters. I hypothesised that these demographic groups would exhibit distinct foraging strategies, which reduce competition and facilitate their coexistence. I analysed the diet of adult male, adult female and juvenile NZ fur seals and adult male Australian fur seals and studied the diving behaviour of adult male and lactating female NZ fur seals and the at-sea movements of juvenile, adult male and lactating female NZ fur seals. Female diet reflected that of a generalist predator, influenced by prey availability and their dependant pups' fasting abilities. In contrast, adult male NZ and Australian fur seals used larger and more energy-rich prey, most likely because they could more efficiently access and handle such prey. Juvenile fur seals primarily utilised small lantern fish, which occur south of the shelf break, in pelagic waters. Juveniles undertook the longest foraging trips and adult males conducted more lengthy trips than lactating females, which perform relatively brief trips in order to regularly nurse their pups. Unlike lactating females, some adult males appeared to rest underwater by performing dives that were characterised by a period of passive drifting through the water column. The large body sizes of adult males and lactating females facilitated the use of both benthic and pelagic habitats, but adult males dived deeper and for longer than lactating females, facilitating vertical separation of their foraging habitats. Spatial overlap in foraging habitats among the age/sex groups was minimal, because lactating females typically utilised continental shelf waters and males used deeper water over the shelf break, beyond female foraging grounds. Furthermore, juveniles used pelagic waters, up to 1000 km south of the regions used by lactating females and adult males. The age and sex groups in this study employed dramatically different strategies to maximise their survival and reproductive success. Their prey and foraging habitats are likely to be shaped by body size differences, which determine their different physiological constraints and metabolic requirements. I suggest that these physiological constraints and the lactation constraints on females are the primary factors that reduce competition, thereby facilitating niche partitioning.

The Earth is experiencing a period of mass extinction due to human development and expansion (Wake & Vredenburg 2008). It has been estimated that 866 animal, plant, fungi and protist species have become extinct in recent history, and 25,821 species were declared either Critically Endangered, Endangered or Vulnerable in 2017 (IUCN 2017). Causal agents of population declines and biodiversity loss include climate change, land clearing, habitat modification and the introduction of exotic competitor or predator species (Vitousek et al. 1997) and disease (Skerratt et al. 2007) which affect species from global to local scales. The magnitude of species loss and threat of further extinctions has caused worldwide attention, instigating efforts to identify and conserve species at risk (Redford & Richter 1999). Species management programs typically aim to identify causal agents of decline, assess species requirements for survival and reproduction and understand population proce sses so that informed decisions can be made to reverse population declines. An important step in this process is gaining an understanding of the factors which affect species distribution (Guisan et al. 2013; Noss et al. 1997). Conservation programs often aim to understand an animal’s distribution by identifying what constitutes habitat. Factors commonly examined include abiotic and biotic attributes of the landscape including available shelter and food, as well as an animal’s interaction with heterospecifics (Campomizzi et al. 2008). In the instance that these factors or interactions correlate with species presence or abundance either positively or negatively, it is assumed that these factors are actively selected for or avoided (Batt 1992). However, additional behavioural factors can affect distribution, such as attraction to (Ahlering et al. 2010) or avoidance of conspecifics (same species) (Keren-Rotem et al. 2006; Stamps 1983), causing strong aggregations or segregation of animal distribution over a landscape, respectively. Despite the influence of these factors on distribution, conspecific attraction and avoidance are not commonly considered by conservation programs when attempting to understand, predict and alter species distributions (Campomizzi et al. 2008). As animals experiencing conspecific attraction or avoidance may deviate from the correlation model assumed by habitat selection, research programs aimed at assisting endangered species cannot afford to ignore conspecific interactions (Manly et al. 2009). A last resort for conservation initiatives is breeding animals in captivity, creating or restoring habitat and translocating animals back into populations that are experiencing population decline or have become locally extinct.

▼ A beach conservation programme protecting nesting loggerhead (Caretta caretta) and leatherback (Dermochelys coriacea) sea turtles in South Africa was started in 1963. As initial numbers of nesting females were low for both species (107 loggerheads and 24 leatherbacks) it was proposed that the protection of eggs, hatchlings and nesting females along the nesting beach would induce population growth and prohibit local extinction. Today, 50 years later, the loggerhead population exceeds 650 females per annum, whereas the leatherback population counts about 65 nesting females per year. The trend for leatherback turtles is that the population has been stable for about 30 years whereas loggerheads are increasing exponentially. Thus, this thesis investigated several life-history traits to explain the differing responses to the ongoing beach conservation programme. Reproductive output and success were assessed for both species; it was hypothesised that environmental conditions are sub-optimal for leatherback turtles to reproduce successfully. It was ascertained that nesting loggerhead females deposit larger clutches than leatherbacks (112 ± SD 20 eggs and 100 ± SD 23 eggs, respectively), but that annual reproductive output per individual leatherback female exceeds that of loggerhead turtles (±700 eggs and ±448 eggs, respectively) because they exhibit a higher intra-seasonal nesting frequency (leatherbacks n = 7 and loggerheads n = 4 from Nel et al. 2013). Emergence success (i.e. the percentage of hatchlings produced) per nest was similar for both species (loggerhead 73.6 ± SD 27.68 % and leatherback turtles 73.8 ± SD 22.70 %), but as loggerhead turtles nest in greater numbers, i.e. producing more hatchlings per year, the absolute population growth potential favours the loggerhead turtle. The second factor investigated was sex ratio because sea turtles display temperature-dependent sex determination (TSD) where extreme incubation temperatures can skew the sex ratio (i.e. feminising or masculinising a clutch). It was suspected that leatherback turtles are male-biased as this is the southern-most rookery (for both species). Further, leatherback nests are generally closer to the high tide mark, which might induce a cooling effect. Standard histological techniques were applied to sex hatchlings and a generalized linear model (GLM) was used to approximate annual sex ratio. Loggerhead sex ratio (2009 - 2011) was estimated at 86.9 ± SE 0.35 % female-biased; however, sufficient replication for the leatherback population was only obtained for season 2010, which indicated a 97.1 % (95 % CI 93.3 - 98.7) female bias. Both species are, thus, highly female-biased, and current sex ratio for leatherback turtles is not prohibiting population growth. Current sex ratios, however, are not necessarily indicative of sex ratios in the past which would have induced present population growth. Thus, to account for present population growth profiles, sex ratios from the past needed to be ascertained. Annual sex ratios (1997 - 2011) were modelled from…

▼ Long-lived, top-level predators, such as some marine mammals, serve as important indicators of ecosystem health. Assessing the abundance and habitat use of such marine top predators is essential for the formulation of effective conservation and management actions. There is considerable concern over the viability of small humpback dolphin opulations across a global scale and a number of studies have raised concerns over their vulnerability to extinction. In light of the recent uplisting of Indian Ocean humpback dolphins (Sousa plumbea) to ‘Endangered’ on the South African Red Data list, there is an urgent need for a greater understanding of the abundance and spatial distribution of this species along the South African coastline. Using small vessels as survey platforms between March 2014 and June 2015, this study attempted to determine the abundance, spatial distribution and habitat preferences of Indian Ocean humpback dolphins along 150 km of South Africa’s south coast. A further aim was to assess the utilisation of the current Marine Protected Area network by humpback dolphins along this coastline relative to areas outside of formal protection. Mark-recapture methods applied to photo-identification data produced abundance estimates of 84 individuals (95% CI: 72-115) within the study area for both open and closed models. An average group size of 3.94 individuals (range 1-12; SD = ± 2.82) was observed during the study, indicating a decrease in average group size of ~45 % from a previous assessment in 2002/03. Such a decline in group size could potentially be a result of a change in social structure in response to reduced prey availability. Spatial analyses of humpback dolphin geographic positions, using a kernel density estimator (KDE) and effort-weighted density grid analyses, indicate that the species is unevenly distributed over the coastal zone within the area. Sightings occurred at the highest densities within Buffels Bay and along Goukamma MPA, followed by Plettenberg Bay, Nature’s Valley, and around the Bloukrans, Elandsbos and Groot River East mouths. Habitat preference was assessed using a standard classification-based method and the results indicate a strong preference, in particular, for Dissipative Intermediate Sandy Coast habitat, followed by Very Exposed Rocky Coast, Intermediate Sandy Coast, Estuarine Shore, Mixed Shore and Inshore Reef habitats. Areas of high humpback dolphin densities appear to be associated with these habitat types, especially with Dissipative-Intermediate Sandy Coast habitat. Humpback dolphins were sighted at relatively low densities along stretches of coastline consisting predominately of Exposed Rocky Shore habitat. Long expanses of this habitat type may limit humpback dolphin movements along the coast. The observed patterns in distribution and habitat preferences may be linked to the availability of prey and/or the avoidance of predators. Average sightings per kilometer travelled (SPUE) indicate that the utilisation of the Robberg and Tsitsikamma MPAs by humpback dolphins was low,…

▼ Anthropogenic climate change has stimulated interest in how species distributions are influenced by climate and how they might respond to global warming. The alpine zone is a harsh ecosystem to inhabit, as it experiences climate extremes daily and seasonally, whilst also exhibiting a steep environmental gradient linked to elevation. This makes it a particularly vulnerable environment in light of anthropogenic climate change, but also an informative situation to explore evolutionary ecology. Flora and fauna inhabiting alpine environments are predicted to be most strongly impacted by future climatic changes, when compared with other global ecosystems. The alpine zone of New Zealand stretches the length of the South Island, and is represented in south and central North Island. It is the result of mountain building since the late Miocene, and is home to a diverse array of endemic flora and fauna. As a relatively large component of native New Zealand habitats that has so far been preserved in higher proportion to other systems, the alpine zone will not be exempt from the effects of global anthropogenic climate change. To date, little research has directly investigated the impact worldwide climate shifts might have on this ecosystem. I investigated the impact that climate change has had, and will have, on New Zealand’s endemic alpine short-horn grasshoppers (Orthoptera: Acrididae), as representatives of New Zealand’s alpine fauna. Four endemic genera contain 13 endemic species that are all freeze-tolerant, open ground specialists. To assess how these species will be affected by future climate change, it was necessary to examine how they have likely responded to past climatic cycles. Phylogenetic relationships were investigated using high-throughput Next Generation Sequencing. The current classification of 13 species into four monophyletic genera was not supported by this study, and the re-classification of members within this group would be appropriate. The mitochondrial (mtDNA) genomes assembled in this analysis, were combined with mitochondrial genome data of Acrididae species from around the world. This allowed identification of species most closely related to the New Zealand alpine taxa and to estimate the timing of divergence using fossil calibration. New Zealand’s alpine grasshoppers form a monophyletic group and share a common ancestor with alpine species from Tasmania. Molecular phylogenetic analysis established that the split of the New Zealand clade from their Tasmanian ancestor probably occurred ~17–19Mya, which is about 12My prior to alpine habitat being available in New Zealand. Thus, the radiation of New Zealand grasshoppers predates the availability of alpine habitat, suggesting they retained shared ancestral cold tolerance for 12 million years or they independently converged on their alpine adaptations. Using the current distributions of New Zealand’s alpine grasshoppers, potential niche spaces were projected for three times periods (Last Glacial Maximum (LGM), current and future). Ecological niche…

▼ 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.

▼ 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.

▼ Titanium dioxide being one of the most important composite precursors has wide range of application due to the unique properties that it exhibits. TiO2 with varying amount of anatase and rutile phases were prepared by controlled hydrolysis of dissolved liquor (Ti—Fe—Cl solution) from dissolution of New Zealand ilmenite followed by calcination of the hydrate sample at different temperatures. The kinetics of ilmenite digestion is examined based on the factors affecting the ilmenite dissolution rate such as acid/ilmenite ratio, additive (iron powder) and optimum dissolution temperature. In hydrolysis, the use of structure determining agents (SDA) that alters the morphology of TiO2 fine particles is analyzed. Samples without SDA have resulted in rutile phase formation at 110°C, while samples with SDA (phosphoric acid/tri-sodium citrate/citric acid) resulted in either anatase phase or mixed phase (both anatase and rutile) at 110°C. The phosphate and citrate ions (0.35% P2O5 and 0.4% citrate) helps in promoting an anatase phase of TiO2 particles. Along with SDA, parameter such as hydrolysis temperature and percentage seed also affects the intermediate product. The influence of calcination temperature ranging from 925°C—1000°C on anatase-rutile phase transformation and variation in crystallite size was studied. X-ray diffraction (XRD) and scanning electron microscopy (SEM) were employed to characterize the resultant TiO2 phase, crystallite size and particle size and shape. The degree of conversion to rutile was higher at higher calcination temperature. Introducing potassium additive (0—2 mass% K2O) in the hydrate sample enhanced the anatase-rutile phase transformation at higher calcination temperature. However, the potassium content in the hydrate sample has a negligible effect on the crystallite size of anatase and rutile after calcination. The XRD pattern shows an increase in the rutile peak intensity and a decrease in the anatase peak intensity with higher calcination temperature. SEM images show that the particle size of the calcined product at 975°C with 1% K2O ranges from 230nm—300nm.

▼ Two species of green gecko (Naultinus stellatus and Naultinus tuberculatus) found in the north and west South Island are endemic to New Zealand and are classified as Nationally Vulnerable (Hitchmough et al. 2016). Detailed information about the ecology, morphology and distribution of these geckos is limited, including what traits are diagnostic, details of their geographic range and it is unknown whether both species hybridise in the wild. My research aimed to investigate if the Denniston and Stockton Plateaus in New Zealand’s South Island represent a putative contact zone between N. stellatus and N. tuberculatus and if natural hybridisation occurs. Naultinus species are known to reproduce with each other in captivity and a few wild caught individuals (n=5) have led to an inference of introgressive hybridisation. In addition, I aimed to collect basic data on the ecology and morphology of both species and a putative hybrid to determine the extent of inter and intraspecific variation in phenotypic traits. I did not find evidence of a contact zone or hybridisation occurring between N. tuberculatus and N. stellatus; all geckos sampled in this study from Denniston and Stockton plateaux were morphologically and genetically part of N. tuberculatus. My results show significant intraspecific phenotypic variation between populations for each species. For example, body colour patterns of some populations are more similar between species than within. However, concordance between genetic markers and colour combinations of mouth and tongue provided evidence of clear species differences, and traits to distinguish the species, despite intraspecific variation of other traits. Finally, I recorded detailed habitat parameters for each individual and documented variation in perch height, both within populations and between sex. This information helps conservation practitioners to implement best practice techniques for green gecko conservation management by determining ecotypes and habitat use, population variance, which can prevent the further decline of both genetic variation and risk to species. Specifically, this research aids the mitigation of negative impacts by mining operations and development, such as is the current threat to the Denniston and Stockton plateaux. – Shortened abstract

▼ 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.

▼ New Zealand is a relatively young country when a comparison is made on early settlement patterns and trends for Australia and Canada. As a consequence, historiography focusing on the mid-nineteenth and early twentieth centuries reflects the dominance of significant numbers of pioneer settlers from England, Scotland and Ireland. The focus for some time has been on quantitative studies that provide a clearer perspective on migrants who were an integral part of the diaspora by virtue of their sheer numbers and mass exodus from the homeland. It is therefore, not surprising that small cluster groups from Orkney and to a lesser extent Shetland in northern Scotland, have ‘slipped through the net’ of Scottish migration studies. This dissertation aims to readdress this oversight and bridge the lacuna that exists for all aspects of Orcadian migration and settlement in the South Island of New Zealand while also providing relevant evidence for Shetland and the Scottish mainland. A decision was also made by the author to include contrastive chapters on both Australia and North America to further develop the Orcadian experience of migration in the nineteenth century. In part this is a restorative history that celebrates the valuable contributions made by kinship cluster groups from Orkney to New Zealand’s early infrastructure. For this purpose a qualitative, longitudinal study was adopted that reflects the contemporary focus for transnational research in preference to the now outdated analysis of diasporic consciousness. Using the contemporary multi-faceted definition of diaspora, does not effectively describe the Orcadian experience. The migration of Orkney men and women over multiple colonial destinations can more accurately and sensitively be interpreted as an odyssey, due also to the multiple geographical locations undertaken prior to final destination. The relatively new discipline of Island Studies has also enabled archipelagos such as Orkney and Shetland to be compared to each other rather than to nearby countries and land masses. The latter has revealed the existence of individual island loyalties that transcend both time and place and provide for more accurate interpretation of migratory patterns adopted in the new settlement. Kinship membership and affiliation, intensified by intermarriage between and within Orcadian families, allowed for the migration of small cluster groups to colonial destinations that were totally dependent on continued chain migration.

▼ This work provides a landscape context and framework for the use of regolith and vegetation in mineral exploration on Kangaroo Island, South Australia. Regolith field observations and the production of a regolith–landform map have improved constraints on the ferricrete plateau formation and also on the landscape history of the Island. The ferricrete and ferruginous materials on Kangaroo Island have been found to be the result of continous formation but have been largely in place since the Eocene. Through field observations, microanalysis and a large scale geochemical survey, the nature of the ferruginous materials and the processes that form them have been examined. Ferrolysis and the movement of groundwater have been interpreted to play major roles in the formation of the ferruginous materials. These processes have a significant impact on the use of the weathered materials for mineral exploration as economic and indicator elements are leached early in the weathering process. Ferruginous materials do contain the signature of mineralisation over areas that contain known deposits, however, the apparent lack of dispersion halos makes these materials difficult to use for a large scale geochemical survey for mineral exploration as target zones may be missed by low sampling densities. Despite this, the ferricrete materials can be useful for mineral exploration, as although potentially only providing small target areas, they do highlight areas of mineralisation. Conversely, the underlying weathered bedrock potentially has less use for mineral exploration as the economic metals have been readily mobilised out of the bedrock during the weathering processes on Kangaroo Island. The biogeochemical surveys were successful in highlighting areas of mineralisation, and displayed a greater dispersion halo than observed in the ferruginous materials. The biogeochemical surveys also helped to provide further information into the processes occurring in the landscape. The eucalypts are interpreted to source groundwater from the weathering zone in the bedrock and effectively pick up elements as they are leached. While displaying a high degree of variability, even over areas of known mineralisation, this dataset was better suited to identifying signals of mineralisation at a larger scale than the ferricrete. A limiting factor on the use of eucalypt for biogeochemical surveys is the occurrence of systematic inter-species variations. This makes large, regional scale surveys difficult, as there is a high possibility that there will not be a consistent vegetation species, resulting in a dataset in which different species need to be compared and potentially excluded in order to correctly identify meaningful anomalies. The xanthorrhoea, overall, was less successful in taking up elements of interest, most likely due to its shallower root system, which is likely to tap into the already leached saprolite or groundwater that has only been recently recharged by meteoric water (diluting any chemical signature of the underlying bedrock).

▼ In 1827, English ex-sailor Nathaniel Walles (Nat) Thomas and Aboriginal Tasmanian Betty were living at Antechamber Bay, in what later became the Hundred of Dudley, Kangaroo Island. They were among the several pre-colonial settlers who had come through the Bass Strait opened up by sealing and whaling industries from the turn of the nineteenth century. When the South Australia Company landed on Kangaroo Island in 1836, there were approximately five Tasmanian Aboriginal men and eight European men, some of whom, like Nat, had small farms of crops and stock. Nat and Betty appear to have been the only parents within this population of 1836 and the only Kangaroo Island pre-colonists to whom the descendants can trace their genealogies today. Their two surviving children, Mary born 1833 and Hannah born c.1839, married South Australia Company settlers; Mary married William Seymour in 1849 and Hannah married Thomas Simpson in 1860. Mary and William remained living near Nat Thomas at Antechamber Bay with their son and two daughters. William worked as a third keeper at the near-by Sturt Lighthouse, Cape Willoughby from 1852-1858. By 1885, however, Mary, by then widowed, moved to Penneshaw. There her son Joseph, a stone-mason, was married and had three daughters, whilst her eldest daughter Emma was married to local labourer Frank Barrett and had four sons and two daughters. The year they married, Hannah and Thomas took up a small lease of land near Penneshaw, known pre-1883 as Hog Bay, and Thomas, previously a Lincolnshire butcher, became the district postmaster. They had seven surviving sons and three daughters. At the age of nineteen, their eldest son, Nathaniel, inherited fifty-one acres of freehold land from his grandfather on his death in 1879. He and his brothers William, Thomas and Stephen worked on increasing this holding and, by 1893, were partners in over eleven thousand acres of land spanning south from Antechamber Bay to Cape Hart. Stephen Simpson also owned one hundred and eighty acres of suburban blocks in Sapphiretown, a township further west, and a forty acre section in Penneshaw where he lived. Nathaniel was a Justice of the Peace and he and his brothers Thomas and William councillors for the District of Dudly. The Simpsons had become an established family; they had houses, land and positions of influence. They could not, however, marry into the other established families. The colonial pastoralist families who had taken up leases on the Hundred of Dudley, predominantly in the 1850’s and 60’s found the pre-colonial descendants unacceptable on the grounds of their Aboriginal ancestry. Having met the colonial families on every other front- acreage, power and respectability-marriage; the mixing of black and white blood, proved the ultimate boundary the pre-colonial descendants could not penetrate. Chapter two discusses the marital frontier between colonised and coloniser, a barrier which was suppressed in daily and…

▼ The Cyanoramphus parakeets are a cryptically coloured group of birds that are distributed across the islands of the South Pacific region. Due to their restricted range and island distributions, species belonging to this genus are considered vulnerable to extinction. However, the extent to which these parrot species are threatened is difficult to determine due to an absence of accurate and reliable population estimates. This research aims to contribute to the conservation of two critically endangered Cyanoramphus parakeets by evaluating the survey methods currently used to estimate population densities. This thesis details the precision and efficiency of distance sampling methods used for monitoring low density parrot populations on small islands. Specifically, examining the annual variation in population size for the critically endangered Tasman Parakeet (Cyanoramphus cookii) and their introduced competitor, the Crimson Rosella (Platycercus elegans), to evaluate the effectiveness of conservation management and species control on Norfolk Island. In addition, the size of three translocated populations of the critically endangered Malherbe’s Parakeet (Cyanoramphus malherbi) were examined to identify if this endemic New Zealand parrot requires further management. Of the distance sampling methods used to monitor parrots, the fixed point survey method was the most suitable method for surveying Tasman Parakeets. This method yielded the highest number of parakeet detections per survey and offered the greatest count precision of the methods examined. On Norfolk Island, the Tasman Parakeet population increased by 126% over four years of intense predator management and nest provisioning. In comparison, the Crimson Rosella population remained stable, despite regular culling to control the population which competes with the Tasman Parakeet. In New Zealand, Malherbe’s Parakeets were detected with varying degrees of success. On Maud Island, no parakeets were detected; however, they were detected on both Blumine Island and Chalky Island. On Blumine Island, the Malherbe’s Parakeet population was moderately abundant, consisting of 202 ± 67 individuals distributed through the mature forest. In comparison, the Chalky Island population of Malherbe’s Parakeet was less extensive and consisted of 84 ± 58 parakeets. This research illustrates the importance of regularly monitoring the size of threatened parrot populations for conservation.

▼ New Zealand forests have been reduced and degraded by gross removal, logging, and the effects of mammals introduced by Polynesian and European settlers. These changes increase the value of the remaining forests, so information on the effects of these disturbances will be useful to inform the management of forest protection. Integrated measurements of C and N cycling within forests can be obtained using foliar stable isotope ratios, which may detect differences between forests resulting from natural or anthropogenic disturbances. This thesis characterises the stable isotopic composition distribution and likely drivers of isotopic variation of vegetation in several central South Island forests, and provides a baseline for future ecological New Zealand studies of present and pre-human vegetation. The largest detected stable isotope variation in modern leaf material was that of δ15N values between the eastern and western podocarp-broadleaf forests. This variation was probably controlled by the lower soil N availability associated with the high rainfall of western forests causing low δ15N values (-8.5 ± 3.5 ‰) relative to an eastern forest (+1.6 ± 1.3 ‰) and global temperate forests (average -2.8 ± 2.0 ‰ (Martinelli et al. 1999)). The significant but slightly higher mean δ15N (0.6 ‰) of a historically selectively logged forest (Saltwater Forest) in comparison to the mean in an unlogged forest (Okarito Forest), on the West Coast, could be attributed to either alteration to N cycling from logging, site differences in topography, or local soil N differences between the forests. Although δ13C showed no significant geographical variation, the well-described ‘canopy effect’ was observed in all modern forests, manifested as a positive covariation between δ13C and vegetation height. Similarly, large taxon-specific differences were observed between δ15N and δ13C values in both modern and fossil leaves. Well-preserved fossil leaves, from sediments c. 4500 years B.P in Pyramid Valley, North Canterbury, had higher δ13C (4.2 ‰) and δ15N (2.5 ‰) values than modern vegetation from Riccarton Bush, Christchurch. The difference between ecosystems spanning several millennia probably reflects ecosystem-scale changes in C and N cycling within New Zealand forests following human arrival, particularly from the degradation caused by invasive animals.
