Variables Influencing Nest Success Of Eastern Wild Turkeys In Connecticut: Nesting Habitat, Home Range-Scale Fragmentation, And Nest Attentiveness, Shelley M. Spohr
Variables Influencing Nest Success Of Eastern Wild Turkeys In Connecticut: Nesting Habitat, Home Range-Scale Fragmentation, And Nest Attentiveness, Shelley M. Spohr
Electronic Theses and Dissertations
Nest success is the most important demographic parameter influencing rates of population change of eastern wild turkeys (Meleagris gallopavo si1vestris) 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 occurred in forested or agricultural landscapes; variables influencing nest success have not been studied in suburban landscapes. My objectives were to: 1 ) quantify survival and reproductive parameters of eastern wild turkey hens in the suburban environment of southeastern Connecticut and compare results to studies conducted in other northeastern states; 2) …
Development Of A Bird-Avoidance Model For Naval Air Facility El Centro, California, Edward J. Zakrajsek
Development Of A Bird-Avoidance Model For Naval Air Facility El Centro, California, Edward J. Zakrajsek
All Graduate Theses and Dissertations, Spring 1920 to Summer 2023
Bird strikes (collisions between birds and aircraft) pose a significant threat to aviation safety. For example, Naval Air Facility El Centro, California, lost an F-18 jet to a bird strike in October 1995. To help combat the bird-strike threat at Naval Air Facility El Centro, I developed a bird-avoidance model as a risk-management tool for the installation. It can be used to schedule flights at NAF El Centro and its two associated practice-bombing ranges during times of low-bird activity. I calculated bird-strike risks and published them in web-page format on both the installation's server and the USGS/Utah State University, College …
The Foraging And Habitat Ecology Of Black Terns In Maine, Andrew Gilbert
The Foraging And Habitat Ecology Of Black Terns In Maine, Andrew Gilbert
Electronic Theses and Dissertations
The population of Black Terns in Maine is small and factors related to the ecology of this species’ foraging and habitat ecology might limit population growth and recovery. The objectives were to (1) determine if diet and provisioning rates are limiting chick growth, (2) identify and rank suitable habitat in Maine, and (3) determine if precipitation patterns and water level dynamics are limiting in Maine. I compared growth rates of chicks in 1998-2000 in Maine to rates from other studies, determined the influence of colony, year, and diet on growth rates and food deliveries and used an energetics model to …
