Environmental drivers of Northern bobwhite fall and winter survival and resource selection in Southwest Missouri
(University of Missouri--Columbia, 2020)
Northern bobwhite (Colinus virginianus) populations have declined over the last 50 years throughout the majority of their historical range, primarily due to habitat loss and degradation caused by modern farming practices, ...
Understanding bacterial zoonotic disease infection and its severity on wildlife populations
(University of Missouri--Columbia, 2022)
Emerging infectious diseases have significantly increased in recent years; approximately 60 percent of these emerging diseases are of zoonotic origin, and of those, around 70 percent were identified to start with wild ...
An investigation of urban bat ecology in Baltimore, Maryland
(University of Missouri--Columbia, 2019)
In North America, bats are a taxon of concern that play an important role in insect control, and their response to urbanization varies. I wanted to discover if evaluating environmental and socioeconomic variables present ...
Conservation biogeography of lotic fishes in the Missouri and Colorado River basins
(University of Missouri--Columbia, 2019)
To improve our understanding of lotic fish ecology and improve conservation efforts, I 1) identified potentially ecologically important tributaries (PEITs) and evaluated their effects on fish assemble structure, 2) evaluated ...
Breeding bird response to pine- savanna and woodland restoration in the Ozark-Ouachita interior highlands
(University of Missouri--Columbia, 2016)
Savanna and woodland communities have experienced drastic losses in the Midwest within the past century and many early-successional bird species have also experienced sharp population declines as well. Pine- savanna and ...
Evaluating the relationship between local food availability and wetland landscape structure in determining dabbling duck habitat use during spring migration
(University of Missouri--Columbia, 2017)
Wetlands in the Nebraska's Rainwater Basin (RWB) have decreased by 90 percent over the past two centuries and are subject to on-going degradation of quality from urban and agricultural land-use practices. Losses in wetland ...
Assessing the vulnerability of stream communities and the consistency and use of biotic indices in least-disturbed streams
(University of Missouri--Columbia, 2016)
The need in freshwater conservation is to understand the current status of aquatic biota so that we can recognize when degradation or changes occur. Because stream habitats and communities are dynamic, it is important to ...
Rural land uses of Scott County, Missouri : landowner decisions and bird communities
(University of Missouri--Columbia, 2016)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] With the vast majority of Missouri under private ownership, private landowners have a large spatial impact on the landscape and the resulting biotic ...
Urban vacant lots : ecological quality and social opportunities in Baltimore, Maryland
(University of Missouri--Columbia, 2016)
Urban vacant lots are a ubiquitous feature in cities worldwide and quickly are becoming a topic of discussion regarding their ecological and social impacts. Vacant lots are typically viewed as discarded spaces within the ...
Impacts of land management practices on breeding bird and plant communities in an urban residential area
(University of Missouri--Columbia, 2016)
Our research establishes a base of knowledge which contributes to our understanding of the factors that determine how residents in Columbia, Missouri make management decisions in their yard and how these decisions benefit ...
Carnivore ecology and conservation : implications for tiger conservation and management in Nepal /
(University of Missouri--Columbia, 2016)
In human-dominated landscapes, conservation and management of large carnivores has been a formidable challenge due to habitat fragmentation, degradation and loss, wildlife persecution, and poaching. Consequently, wide-ranging ...
Linking wetland management decisions to secretive marsh bird habitat use during spring migration and summer breeding on public wetlands in Missouri
(University of Missouri--Columbia, 2015)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] The extent to which secretive marsh birds rely on wetlands in Missouri during spring migration is relatively unknown. My objective for chapter one was ...
Light reflectance patterns of decayed wood with implications for the visual ecology of woodpeckers
(University of Missouri--Columbia, 2016)
Birds rely on eyesight for many aspects of their behavior and ecology, and a majority of diurnal species have thus evolved complex visual systems that include sensitivity to near ultraviolet (UV; 300-399 nm) wavelengths. ...
Roost site selection by Indiana bats (Myotis sodalis) and comparison of foraging habitat selection by morphologically similar bat species in bottomland hardwood ecosystems
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] While bottomland hardwoods used to encompass a large portion of the south-central United States, due to clear cutting for agriculture and other purposes, ...
Evaluating sampling methods and investigating distribution and richness of fish and amphibians in Missouri wetlands
(University of Missouri--Columbia, 2017)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Freshwater wetlands are some of the most imperiled ecosystems on the planet, meaning species that depend on them are at great risk. In Missouri, wetland ...
Development and validation of standardized sampling protocols for assessing freshwater mussel populations in Missouri
(University of Missouri--Columbia, 2017)
Freshwater mussels are among the most threatened aquatic fauna in North America. Given the need for continued monitoring of threatened mussel species, an evaluation of the effectiveness of metrics from visually-based ...
The demography of Atlantic brant (Branta bernicla hrota)
(University of Missouri--Columbia, 2022)
Animal population dynamics are driven by variation in survival and productivity. Long-lived species such as Arctic-nesting geese often are characterized by high adult survival and low but highly variable annual reproductive ...
Habitat selection and movement by spotted bass and shorthead redhorse downstream of a hydropeaking dam in Missouri
(University of Missouri--Columbia, 2018)
Flow alteration caused by hydropeaking dams may disrupt the natural flow regime and impact physical habitat and biological community, thus threatening the health of freshwater ecosystems. Life history strategies of fish ...
Factors influencing the space use of a nonhunted population of eastern wild turkeys
(University of Missouri--Columbia, 2022)
Wild turkeys (Meleagris gallopavo) have been an economically and culturally important game species in North America for many decades. Recent declines in abundance and productivity in several populations of wild turkeys, ...
