A Study of factors influencing a non-cyclic, island population of snowshoe hares
… observed demographic differences between Jacquot Island and mainland snowshoe hare (Lepus americanus) populations, in the southwestern Yukon. The population dynamics of snowshoe hares on Jacquot Island have been observed to differ from the dynamics of a population undergoing a "10-year cycle," …

Alaskan Eskimo and Polynesian Island Population Skeletal Anatomy: The "Pacific Paradox" Revisited Through Surface Area to Body Mass Comparisons
… measurements on two climatically different populations, Alaskan Eskimo and Pacific Island groups. The “Pacific Paradox” has been widely discussed, but research using direct comparisons between this Pacific population and cold climate groups has received little attention. The methods employed …

Population structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori)
… as a tool to uncover information about the population structure and genetic variation in Hector’s dolphin (Cephalorhynchus hectori), to track population declines and to assess the evolutionary origins and taxonomic status of this species. A high-resolution genetic analysis of population …

Comparative Mitochondrial DNA Sequence Diversity in Isolated and Open Populations of Southern Flying Squirrels
Three populations of Southern flying squirrels were studied in the Ouachita Mountains of Arkansas to assess the impact of population subdivision-due to island formation--on the population genetics of Glaucomys volans. One island, one mainland, and one open population were investigated. A 367 …

The Genetic Structure of the Kuwaiti and Failaka Island Populations: Y-chromosome & Mitochondrial DNA Variation
… migrations among the three continents. The populations of the Arabian Peninsula have been investigated to better understand their evolutionary history. This dissertation investigated the paternal genetic structure of the Kuwaiti and Failaka Island populations using 15 loci Y-STR data. In …

Evaluation of capture-recapture estimators using a cyclic snowshoe hare population
… when applied to a cyclic snowshoe hare population in the Kluane Lake area in the Southern Yukon. The estimation models and model selection routine of program CAPTURE, and the Jolly-Seberopen model were evaluated. Two independent approaches were used to evaluate estimators: 1) Island …

Bioacoustic Studies of Population Size and Microdialects in an Island-Living Savannah Sparrow Population
… of passive acoustic monitoring in estimating population size and annual survival in an island population of Savannah Sparrows. Six years of data reveal that passive acoustic monitoring with autonomous recorders provides accurate underestimates of population size and annual survival. I found …

Physiological variation of Garry oak (Quercus garryana) seedlings to drought stress
… [Fagaceae]) seedlings that grow in distinct populations in Washington state, in order to aid in restoration efforts by informing growers of the potential differences between the acorn collection sites. Acorns from six Washington populations east of the Cascades, as well as one population from …

Population genomics of Sulfolobus islandicus: genome-wide recombination and antagonistic interactions
… of the era of genomic sequencing of natural populations of microorganisms, it has been revealed that genetic recombination is not just a useful laboratory tool for microbial geneticists, but instead a prominent feature of microbial population biology. Conceptual models of how microbial …

Geographic and Ontogenetic Variation of Venom in the Rattlesnakes Crotalus oreganus oreganus and Crotalus o. helleri
… to examine the venome of four C. o. helleri populations. Substantial geographic variation existed, with small basic peptides (myotoxic β-defensins) expressed in large amounts by all populations, metalloproteinases abundant in two populations but only moderate and trace amounts in the other …

Scourge or Sustenance: Using microfauna to explore the palaeoenvironment and palaeoeconomics of Epipalaeolithic and early Neolithic communities in Anatolia.
… years. Evidence for human impact on house mouse populations at Çatalhöyük were also discovered, with specimens from a single building exhibiting molar shape change consistent with that of an isolated island population. The analysis of these assemblages has shown that microfauna can provide a …

Ecological role and conservation status of the endangered, native Fijian free-tailed bat (Mops bregullae, Felten 1964) in fragmented forest habitats
… mammals and contain the most secure global populations of several threatened taxa. Bats are ecologically important as they provide critical ecosystem services of pollination and insect control in both agricultural and forest ecosystems. The ecology of the endangered Fijian freetailed bat …

The emergence of Mailu as a central place in the prehistory of coastal Papua
At the close of prehistory, the small Papuan island of Mailu was the location of a settlement that can be described as a central place. It was 'central' in that (1) with respect to the pattern of communications among contemporary sites in the area, it enjoyed a distinct relative locational …

Changes in Gene Expression and Viral Titer in Varroa Jacobsoni Mites After a Host Shift Asian to European Honey Bees
… colonies. However, we have sampled an island population of <em>V. jacobsoni</em> that is highly destructive to <em>A. mellifera,</em> the primary species used for pollination and honey production. These recently discovered populations of mites represent an enormous threat to apiculture. …
