Conservation Value Of Working Landscapes In Mesoamerica For Nearctic-Neotropical Migratory Birds, Samuel L. Oliveira
Conservation Value Of Working Landscapes In Mesoamerica For Nearctic-Neotropical Migratory Birds, Samuel L. Oliveira
Dissertations, Master's Theses and Master's Reports
Populations of many of Nearctic-neotropical migratory birds have declined in the past several decades, recent estimates suggested a dramatic loss of 2.5 billion birds over the past 50 years in North America. Habitat loss and degradation represent a major threat in the tropics. Managed agroecosystems have the potential to mitigate some impacts of land conversion, however, little is known regarding the habitat quality provided by working landscapes in the overwintering range. In this research, we surveyed the migratory bird community in the rapidly expanding oil palm plantations in southern Mexico; and also the declining population of the Wood Thrush ( …
Display Site Selection By Male Ruffed Grouse In The Upper Great Lakes Region, Seth Finkel
Display Site Selection By Male Ruffed Grouse In The Upper Great Lakes Region, Seth Finkel
Dissertations, Master's Theses and Master's Reports
The Ruffed Grouse (Bonasa umbellus) is widely known for its characteristic territorial drumming display. In this study, I used ruffed grouse drumming survey data from Minnesota and Michigan, in a series of mixed logistic models, to identify drivers of drumming log selection by reproductive male ruffed grouse. I collected drumming stage data utilizing a paired-random sampling structure. I used information theoretic model selection to examine three sets of a priori mixed logistic models: one for the entirety of my Minnesota dataset, one consisting of stages identified in aspen stands in Minnesota, and one for my Michigan dataset. In …
Using Remote Site Incubators For Re-Introduction Of Arctic Graylng (Thymallus Arcticus) To The Big Manistee Watershed, Sunflower Wilson
Using Remote Site Incubators For Re-Introduction Of Arctic Graylng (Thymallus Arcticus) To The Big Manistee Watershed, Sunflower Wilson
Dissertations, Master's Theses and Master's Reports
Remote Site Incubators (RSIs) were developed for the incubation of salmonid eggs directly at a field site to enhance success and imprinting of young. These have been employed in the re-establishment of Arctic Grayling in Montana and are being laboratory tested for possible reintroduction of this species in the Big Manistee River, MI. Arctic Grayling, Rainbow and Brook Trout eggs, obtained from state hatcheries, were reared in a laboratory using flow through lake water to assess egg and fry survival using RSIs. Dead eggs and fry were removed daily and observations of developmental stages recorded. Rainbow Trout eggs were evaluated …
