Ethical Foundations For The Lethal Management Of Double-Crested Cormorants (Phalocrocorax Auritus) In The Eastern United States: An Argument Analysis, Chelsea Batavia, Michael Paul Nelson Dec 2018

Ethical Foundations For The Lethal Management Of Double-Crested Cormorants (Phalocrocorax Auritus) In The Eastern United States: An Argument Analysis, Chelsea Batavia, Michael Paul Nelson

Chelsea Batavia, PhD

Lethal management of Double-crested Cormorants (Phalocrocorax auritus) has been implemented in many areas of the United States. In this paper, the philosophical method of argument analysis is used to assess ethical premises underlying the proposition that Double-crested Cormorant populations should be culled to reduce pressures on wild fisheries in the Great Lakes region of the eastern USA. This influential argument has been used to justify the destruction of more than half a million Double-crested Cormorants and hundreds of thousands of their nests and eggs. Three versions of the argument are formulated and assessed. It is shown that each of the …

Plastron Pigmentation Variation In A Coastal Turtle Species Of Conservation Concern (Malaclemys Terrapin), Beth Reinke, Steven Pearson, Will Selman Dec 2017

Plastron Pigmentation Variation In A Coastal Turtle Species Of Conservation Concern (Malaclemys Terrapin), Beth Reinke, Steven Pearson, Will Selman

Beth Reinke

Malaclemys terrapin inhabits salt marshes of the coastal United States and has been historically divided into seven subspecies. Two of the described subspecies, M. t. pileata and M. t. littoralis, occur along the western and eastern coastlines of Louisiana, respectively. To better understand potential boundaries of these two subspecies, we documented pigmentation variation of the plastron along the coast of Louisiana where the subspecies supposedly intergrade. Photographs of the plastron were taken of captured individuals and we quantified pigment with a photoprocessing software (ImageJ). We found pigmentation differences between sexes, with females having lighter plastrons than males. The plastron pigmentation …
