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 …
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 ( …
Effects Of Dissimilar Silvicultural Techniques On Small Mammal Communities In Michigan's Upper Peninsula, Breanna R. Gusick
Effects Of Dissimilar Silvicultural Techniques On Small Mammal Communities In Michigan's Upper Peninsula, Breanna R. Gusick
Dissertations, Master's Theses and Master's Reports
Small mammal populations, and predators reliant upon them as food resources, are often challenged by conflicting objectives of timber production and maintenance of quality habitat. With over 70% of the landscape forested, and nearly one-third of the land privately owned, Michigan’s Upper Peninsula (UP) is a matrix of independent management strategies. To assess the effects of various silvicultural regeneration methods on small mammal populations in the Upper Peninsula, we trapped small mammals in experimental silviculture plots, whereby treatments varied by regeneration method (amount of residual canopy cover) and site preparation (i.e., control, tip-up, and scarification), and deer exclosures. We used …
Livestock-Wildlife Dynamics And Subsequent Human Responses In Marginalized Communities Within Mexico’S Nationally Protected Areas, Deanna Seil
Dissertations, Master's Theses and Master's Reports
Entering the planet’s sixth mass-extinction, monitoring biodiversity and the factors which affect it is of the utmost importance. This study on the interaction of humans and their livestock with wildlife, and the impact of this interaction on wildlife conservation, took place in Santiago Coatepec, located within the Tehuacán-Cuicatlán Biosphere Reserve in Mexico. Wildlife interactions with livestock may depend upon species, season, ecological characteristics of the area, and livestock management practices. Using camera traps, field data, and interview data, I quantified livestock impact on wildlife behavior and community beliefs. Over two years, camera traps at 18 stations recorded 709 wildlife videos …
Plant Community Response To Novel Silvicultural Treatments In Great Lakes Northern Hardwoods, Stefan F. Hupperts
Plant Community Response To Novel Silvicultural Treatments In Great Lakes Northern Hardwoods, Stefan F. Hupperts
Dissertations, Master's Theses and Master's Reports
The objective of this dissertation is to assess plant community response across a range of silvicultural disturbances and test ecological hypotheses to better inform ecologists and forest managers. To provide context for the utility of revising silvicultural systems, I review natural disturbance regimes and historical practices that have shaped contemporary Great Lakes northern hardwood forests (Chapter 2). Further, I identify important ways to expand the silvicultural toolbox and better emulate natural disturbance regimes. Building on this theoretical underpinning, I investigate the initial regeneration and plant community response to two novel silvicultural experiments: the Northern Hardwood Experiment for Enhancing Diversity (NHSEED) …
The Impact Of Household Biocides And Antibiotics On Aquatic Microbial Community Composition, Abdulaziz Saud M Alrashdi
The Impact Of Household Biocides And Antibiotics On Aquatic Microbial Community Composition, Abdulaziz Saud M Alrashdi
Dissertations, Master's Theses and Master's Reports
Triclosan (TCS) is antimicrobial agent that is used in a lot of consumer products, including toothpaste, liquid and bar soap, and cosmetics. TCS has been found in many lakes and rivers in the United States. However, The Food and Drug Administration (FDA) banned TCS recently and it will no longer be used in household products. Despite the recent ban, TCS is known to persist in the environment and may have long-term impacts. We conducted an experiment on using fresh water from three locations Houghton, Green Bay and the Huron Mountains. Our goals in the study is to assess the impact …
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 …
Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar
Neutral And Adaptive Genetic Variation In North American Hardwood Tree Species, Sudhir Khodwekar
Dissertations, Master's Theses and Master's Reports
'Northern Hardwoods,’ are a characteristic composition of multiple tree species and a part of the rich and diverse northeastern forests. Hardwoods e.g. oaks (Quercus: Fagaceae and Sugar maple), serve as foundation species and offer ecological and economical gains to wildlife and humans. Most of the forest trees go through many biotic and abiotic stresses, for example climate change in their long life span. To overcome these threats and to adapt to changing conditions, tree species need to maintain variation especially in adaptive genes. Therefore, it is necessary to analyze genetic diversity within forest tree populations and take appropriate …
