(Halifax, N.S. : Saint Mary's University, 2022-04)Industrial whaling in the early to mid 20th century severely depleted the population of blue whales in the North Atlantic. Due to this reduction in population it is likely that the current population of blue whales in ...
-
(Public Library of Science, 2014-06-12)Species biogeography is a result of complex events and factors associated with climate change, ecological interactions, anthropogenic impacts, physical geography, and evolution. To understand the contemporary biogeography ...
-
(Halifax, N.S. : Saint Mary's University, 2018)Accurate abundance estimates are important for the management of species. Many abundance estimates are based off of capture-mark-recapture analyses which have several limitations that can reduce the accuracy of abundance ...
-
(Public Library of Science, 2017-11-02)On the North American Great Plains, several snake species reach their northern range limit where they rely on sparsely distributed hibernacula located in major river valleys. Independent colonization histories for the river ...
-
(Halifax, N.S. : Saint Mary's University, 2022-04)Beluga whales (Delphinapterus leucas) migrated to the St. Lawrence Estuary near the end of the Holocene glacial retreat, when dry land emerged. The population currently inhabiting the St. Lawrence shows strong ...
-
(Halifax, N.S. : Saint Mary's University, 2019)Offspring that are a product of inbreeding often have reduced fitness, known as inbreeding depression. Though our understanding of the impacts of inbreeding depression in wild populations is in its infancy, it is thought ...
-
(Halifax, N.S. : Saint Mary's University, 2013)A concern of conservation biology is the viability of small, isolated populations because these are expected to lose genetic diversity at a greater rate than large populations due to genetic drift. Factors such as non-random ...
-
(Halifax, N.S. : Saint Mary's University, 2017)The goal of this project was to assess the influence that genetic characteristics at gamete compatibility genes have on the reduced reproductive rates in the endangered North Atlantic right whale. To do this candidate genes ...
-
(The Royal Society, 2017-08-30)Fertilization represents a critical stage in biology, where successful alleles of a previous generation are shuffled into new arrangements and subjected to the forces of selection in the next generation. Although much ...
-
(Wiley, 2014-11)Characterizing movement dynamics and spatial aspects of gene flow within a species permits inference on population structuring. As patterns of structuring are products of historical and current demographics and gene ...
-
(Halifax, N.S. : Saint Mary's University, 2016)The purpose of this project was to understand how genetic factors may be influencing cancer susceptibility and mortality patterns in the St. Lawrence beluga. To assess if variation along candidate genes are influencing ...
-
(Halifax, N.S. : Saint Mary's University, 2014)The little brown bat (Myotis lucifugus) is a vagile species occupying a large distributional throughout most of North America. Myotis lucifugus separate into female maternity colonies to rear their young, and males appear ...
-
(Halifax, N.S. : Saint Mary's University, 2014)The techniques for genetic species identification and inferring past population sizes are being utilized in more fields than just population genetics. Anthropology, conservation biology, and species management are also ...
-
(Halifax, N.S. : Saint Mary's University, 2021)Knowing the age of individuals within a population provides a wealth of information that is important for understanding aspects of their biology, including many aspects that are important for conservation. Some of these ...
-
(Halifax, N.S. : Saint Mary's University, 2017)Limited gene flow can divide a species into populations, forming population structure. Population structure is important for evolution and conservation so methods for detecting them were developed. With prior assumptions ...
-
(Halifax, N.S. : Saint Mary's University, 2013)The St. Lawrence River beluga whale (Delphinapterus leucas) population is geographically and reproductively isolated from other beluga populations. This small population is also endangered, therefore learning the population ...
-
(Public Library of Science, 2015-05-05)During late summer and early autumn, temperate bats migrate from their summering sites to swarming sites, where mating likely occurs. However, the extent to which individuals of a single summering site migrate to the same ...
-
(Wiley-Blackwell, 2013-09)Although small populations are expected to lose genetic diversity through genetic drift and inbreeding, a number of mechanisms exist that could minimize this genetic decline. Examples include mate choice for unrelated mates ...
-
(Halifax, N.S. : Saint Mary's University, 2015)It is often difficult to asses the social and mating structure of populations through the usage of observational methods alone. Molecular methods give greater insight into patterns of relatedness within populations, and ...
-
(Halifax, N.S. : Saint Mary's University, 2013)Altruistic behavior, such as caring for the offspring of others, is an intriguing phenomenon observed in several mammalian species. One of the most successful theories for explaining how this behavior could have evolved ...
