Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels Aug 2002

Estimating Population Numbers Of Black Bears (Ursus Americanus) In Eastern Kentucky Using Microsatellite Analysis, Kelly Vowels

Masters Theses & Specialist Projects

Black bears (Ursus americanus) occur sporadically in eastern Kentucky, and there is some evidence that a breeding population exists. In order to establish management practices to enhance the black bear population in Kentucky, information about this population is needed. However, until recently, no population size estimate has been available. Gathering information on black bears is difficult because black bears are elusive animals. The development of new molecular methods has made it easier to track and gather information on black bear populations, including estimates of population size. Molecular markers are particularly useful in that they do not require physical contact with …


The Future Of Stock Enhancements: Lessons For Hatchery Practice From Conservation Biology, Culum Brown, Rachel L. Day Jun 2002

The Future Of Stock Enhancements: Lessons For Hatchery Practice From Conservation Biology, Culum Brown, Rachel L. Day

Aquaculture Collection

The world’s fish species are under threat from habitat degradation and over-exploitation. In many instances, attempts to bolster stocks have been made by rearing fish in hatcheries and releasing them into the wild. Fisheries restocking programmes have primarily headed these attempts. However, a substantial number of endangered species recovery programmes also rely on the release of hatchery-reared individuals to ensure long-term population viability. Fisheries scientists have known about the behavioural deficits displayed by hatchery-reared fish and the resultant poor survival rates in the wild for over a century. Whilst there remain considerable gaps in our knowledge about the exact causes …


A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller Jan 2002

A Role For Natural Resource Social Science In Biodiversity Risk Assessment, Philip J. Nyhus, Frances R. Westley, Robert C. Lacey, Philip S. Miller

Faculty Scholarship

Biologists have made considerable progress in developing realistic simulation models to predict extinction risks for threatened species. Social scientists have to date had a more limited role in these efforts. This limited involvement comes despite the growing acknowledgment by population biologists and simulation modelers that this additional input is necessary for these models to accurately reflect the impact of humans and human-dominated landscapes on wildlife populations. We argue that collaborations among social and biological scientists can provide unparalleled opportunities to develop new conceptual and simulation tools for biodiversity risk assessment. One challenge is that while the value of interdisciplinary research …


The “Nuisance” Wildlife Control Industry: Animal Welfare Concerns, John Hadidian, Laura J. Simon, Michele R. Childs Jan 2002

The “Nuisance” Wildlife Control Industry: Animal Welfare Concerns, John Hadidian, Laura J. Simon, Michele R. Childs

Wildlife Population Management Collection

The recent and rapid growth of the private “nuisance” wildlife control industry follows the unparalleled current period of urban and suburban expansion. Nuisance wildlife control businesses range from simple home-based services to sophisticated franchised businesses. The nuisance wildlife control operator may hold an advanced degree in the wildlife sciences, or simply be an entrepreneur without formal education or even background experience in wildlife. State and federal agencies may participate directly or indirectly in nuisance wildlife control, in activities ranging from dissemination of advice or information to actual participation in programs that may lead to removal of animals. Naturally, all of …


Resolving Conflicts Between People And Canada Geese: The Need For Comprehensive Management Approaches, John Hadidian Jan 2002

Resolving Conflicts Between People And Canada Geese: The Need For Comprehensive Management Approaches, John Hadidian

Wildlife Population Management Collection

Canada geese have become established and are now numerous enough in many urban and suburban areas that conflicts with humans have become frequent. Although potential threats to human health are often cited as a justification to manage goose populations, currently available science suggests that this is not a serious issue. This leaves the primary concern as one of aesthetics– people do not like having to deal with what can sometimes be copious amounts of goose droppings. Animal welfare interests have questioned the humaneness of different roundup and killing programs, and advocated non-lethal approaches and egg addling. Both approaches currently are …


A Late Quaternary Paleoecological Record From Caves Of Southern Jamaica, West Indies, Donald A. Mcfarlane, Joyce Lundberg, A.G. Fincham Jan 2002

A Late Quaternary Paleoecological Record From Caves Of Southern Jamaica, West Indies, Donald A. Mcfarlane, Joyce Lundberg, A.G. Fincham

WM Keck Science Faculty Papers

Studies of an unusual and diverse system of caves in coastal southern Jamaica have yielded a paleoclimatic record associated with a fossil vertebrate record that provides useful insights into the poorly documented paleoecology of latest Wisconsinan and Holocene Jamaica. Episodes of significantly increased precipitation during the Holocene have left characteristic deposits of speleothems, and have supported both faunal and archaeological communities that were dependent on these mesic conditions. Deposits of fossil bat guano preserved in the caves provide a δ¹³C record of alternating mesic and xeric climatic episodes that supports the interpretation of the faunal and archaeological record.


Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn Jan 2002

Canis Lupus Cosmopolis: Wolves In A Cosmopolitan Worldview, William S. Lynn

Human and Animal Bonding Collection

The subject of wolf recovery in North America sparks heated controversy, both for and against. This paper explores how this subject is informed by cosmopolitan worldviews. These worldviews pull nature and culture into a common orbit of ethical meaning, with implications for the normative relationships that ought to pertain in landscapes shared by people and wolves. This theoretical outlook is illustrated using the controversy over wolves in the northeastern region of the United States. I conclude with a set of reflections on theorizing the cosmopolis, the interpretation of cosmopolitan landscapes, and living with cosmopolitan wolves.
