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 ...
A genetic approach to determine river otter abundance in Missouri
(University of Missouri--Columbia, 2010)
Extirpated from Missouri by the 1930s, river otters (Lontra canadensis) were reintroduced by the Missouri Department of Conservation (MDC) from 1982-1992. Since the reintroductions, concerns over the legitimacy of otter ...
Influence of streambed substrate type and watershed properties on seston algal abundance
(University of Missouri--Columbia, 2008)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] In this age of growing water quality issues, it is crucial to identify factors which impact stream water chemistry. In the Gulf of Mexico a growing ...
Multi-scale factors influencing detection, site occupancy and resource use by foraging bats in the Ozark Highlands of Missouri
(University of Missouri--Columbia, 2007)
Conservation of bat populations requires understanding the associations between bats and their use of resources. We used maximum likelihood to estimate probability of site occupancy using acoustic data for ten species of ...
Evaluation and development of black-footed ferret resource selection models
(University of Missouri--Columbia, 2009)
recently developed ferret RUF generated from observations of ferrets on an adjacent colony; and (2) development of new RSFs, while evaluating influences on resource selection (e.g., predators and resource connectivity) not yet investigated for M. nigripes...
Resource selection by black-footed ferrets in relation to the spatial distribution of prairie dogs
(University of Missouri--Columbia, 2007)
Once extinct in the wild, the black-footed ferret (Mustela nigripes) is one of the rarest mammals in North America. Reintroductions of ferrets at 13 sites over 10 years have resulted in only 3 self-sustaining populations. ...
Assemblage structure and shallow-water habitat use by small-bodied fishes at lower Missouri River sandbars
(University of Missouri--Columbia, 2007)
-dike sandbars. Instead, fishes aligned along a depth-velocity gradient relative to body length. Shallow (ca. 0.12m), near-shore areas were dominated by fishes [less than] 35 mm TL during the day, but larger fishes (e.g., 70 mm TL) moved nearer to shore at night...
