The last stages of a global mass extinction event (GME) that started in the Pleistocene is likely to be continuing across the nations of the Earth. In the United States (“Nation”), it will likely climax (“Climax”) by 2100 AD when it will wipe out about 80% of endemic, vertebrate…
A recent re-tabulation of government wildlife kill data reveals that British Columbia (BC) Conservation Officers, in the last 8 years (2011-2019), have killed 4,341 black bears, 162 grizzly bears, and 780 cougars (Casavant, 2020). These killing statistics raise broad questions a…
CRYOPRESERVATION OF FISH GAMETES
Understanding the reproductive physiology and endocrinology of fishes is essential for captive maturation and seed production in the field of aquaculture. Studying the spermatology of fishes is a comparatively new focus in aquaculture, which has emerged as an important area of f…
Seas and oceans cover 71 % of the earth's surface and they are home to 80% of all life found on the planet . Among the different components of marine life, the phylum Cnidaria (formerly Coelenterata) has been reported to be responsible for more envenomations than any other marin…
Endocrine disruptors: part I - II

Wildfires shaped subalpine forests in the northern US Rocky Mountains for millennia. However, recent climate-driven increases in fire frequency and severity are constraining postfire tree regeneration in forests dominated by fire-sensitive obligate-seeder conifers via reduced pr…
This dissertation argues that history, values, and politics/institutions play roles in conjunction with science when there is conflict over the process of formulating and implementing environmental policy. It considers how power influences wildlife conservation, specifically bla…
Pure Michigan Hunt (PMH) is a new multi-species drawing that offers its three winners a license to hunt elk, black bear, antlerless deer, spring and fall turkey, and waterfowl. Building awareness, interest and participation in the drawing is vital to the success of the campaign.…

The Caspian region and specifically the Apsheron peninsula of Azerbaijan is known to be polluted with a variety of environmental contaminants, making risk assessment difficult. The wetlands of Sumgayit contain particularly complex mixtures of contaminants. Flow cytometry and the…
Mast is an important food resource for wildlife in south Texas, particularly for the economically important white-tailed deer and wild turkey, but also for collared peccary, raccoon, and wood rat. Wild pigs also exist throughout south Texas, and utilize mast in their diet as wel…
Ecotoxicology studies attempt to evaluate the consequences of exposure to environmental contaminants by defining exposure and effects parameters across multiple levels of biological organization. Genetic markers are well-suited for these studies as they can track both somatic an…
Developmental psychologists argue that children's moral reasoning abilities develop through a sequence of stages, stimulated by interactions with the social environment. This thesis attempts to extend the theory of human moral reasoning development to interpret ethical thinking …
