An Analysis of the Economic Factors and Changes in Land-Use Associated with the Transition to a Beef Feedlot System in Waterloo County
Contributor(s): Gary B. Griffith
Agricultural geography in Canada has been largely neglected as a field of geography until relatively recently. This is evidenced by several factors. First, until the mid 1960's, there were only two different agricultural geography courses offered in Canadian universities. Secondly, in that same...
Variables Influencing Nest Success of Eastern Wild Turkeys in Connecticut: Nesting Habitat, Home Range-Scale Fragmentation, and Nest Attentiveness
Contributor(s): Shelley M. Spohr, Daniel J. Harrison (adviser), Frederick A. Servello (adviser)
Nest success is the most important demographic parameter influencing rates of population change of eastern wild turkeys and many variables operating at multiple spatial and temporal scales may influence whether a nest is successful. Most studies of nest success and survival of turkeys have...
Shrimp Aquaculture and Aguadulce: A Broken Partnership
Contributor(s): Sylvia M. Bolanos, Richard Weisskoff (adviser)
A socio-economic impact study was conducted in Aguadulce, Panama to analyze the viability of the shrimp aquaculture industry. Two visits in 2004 and 2010 document the changes the industry underwent through the use of a survey and interviews of knowledgeable informants. Interviews were conducted...
