Resumen

Bees provide the essential ecosystem service of pollination, contributing ca. 35% of global food production, but declines in their populations have been reported worldwide. Currently, one third of the Irish bee fauna is listed as threatened. This thesis aimed to provide essential information on the conservation genetics and ecology of Irish bees. A comparis?n of published data on microsatellite markers revealed that haplodiploidy alone had no influence on genetic div~rsity whereas eusociality probably reduced it. Globally, >90% of bee species are solitary, rather than social. Ireland has over

Resumen

New Zealand sea lion (Phocarctos hookeri) is a pinniped endemic to New Zealand and is among the rarest of sea lion species. New Zealand sea lions are incidentally caught in the trawl fishery for squid around the Auckland Islands, and a sea lion catch-limit or Fishing Related Mortality Limit (FRML) is used to manage this interaction. Since 2003 such limits have been calculated using an age-structured Bayesian population model. One problem with this approach is that several key demographic parameters have had to be assumed, or are based on very few data. Archaeological and other historical rec

Resumen

The bottlenose dolphins of Fiordland, New Zealand, live at the southern limit of the species' worldwide range. They are exposed to impacts from tourism and habitat modification, particularly in Doubtful Sound, and their conservation requirements are presently unclear. Dolphin abundance was estimated in Doubtful Sound using photo-identification census and capture-recapture techniques (56 individuals; 95% CI: 55-57), detecting a decline of 34-39% over 12 years among adults and sub-adults (>3 years old). The cause of this decline was investigated via demographic modelling in Doubtful Sound and a

Euphydryas aurinia has undergone a widespread national decline in recent years. This decline is quantified at a 10km scale. The distribution in 2020 was predicted for E. aurinia from the 1995-99 distribution, assuming that the current causes and pattern of decline continued. The predicted distribution in 2020 represented a 48% loss in 10km grid square records, with only the core regions surviving. The distribution and per

Conservation of phenotypically variable taxa such as the European whitefish (Coregonus lavaretus) can be particularly challenging. In this thesis it is argued that the recent designation of seven native C. lavaretus populations as three endemic species (C. clupeoides, C. stigmaticus and C. pennantii) by Kottelat & Freyhof (2007) are incorrect and cannot be substantiated with the results presented here. However, evidence for important infra-specific variation between populations has been found. Two native Scottish populations of C. lavaretus show considerable variation in morphology, trophic ec

Resumen

Oceanic islands contribute significantly to global biodiversity due to the high levels of endemism they exhibit.

The objectives of my PhD were threefold: to understand the current status of the St. Helena Plover, to investigate aspects of its environment that may threaten its persistence, and to compare conservation options.

Resumen

In order to prevent species extinctions, conservation strategies need to incorporate the identification and mitigation of the root causes of population decline with an assessment of vulnerability to genetic and stochastic factors affecting small populations. Species or populations with small ranges, such as those on islands, are particularly vulnerable to extinction, and deficient knowledge of these species often impedes conservation efforts. The Bahama Swallow (Tachycineta cyaneoviridis) is an endangered secondary cavity-nester that only breeds on three islands in the northern Bahamas: Abaco,

Reproductive science plays an important role in conservation biology. Quantitative studies of basic reproductive biology in wildlife are critical for the development of successful assisted reproductive technologies. Investigation of the volume regulatory mechanism of spermatozoa could produce options to improve the cryopreservation of spermatozoa and provide a non-hormonal contraceptive option for men, both of which could have significant impacts on global biodiversity preservation.

The Blue Mountains Water Skink (Eulamprus leuraensis), restricted to the endangered habitat of highland peat-swamps, is known from fewer than 60 isolated sites in the Blue Mountains region of south-eastern Australia. The sole endemic vertebrate of the region, this scincid lizard is imperilled by many threats. From three years of field surveys, I show that E. leuraensis live almost exclusively within swamps, with very few inhabiting the swamp margins and none recorded in the surrounding woodland. Paradoxically, this endangered species appears to be the most abundant vertebrate in these swamps.
