Thomas W. Small, Sara E. Bebus, Eli S. Bridge, Emily K. Elderbrock, Stephen M. Ferguson, Blake C. Jones, Stephan J. Schoech Plasma glucocorticoid (CORT) levels collected within 3 min of capture are commonly believed to reflect pre-stressor, baseline CORT levels. Differences in these “baseline” values are often interpreted as reflecting differences in health, [...]

Shelly C. Wu, Elizabeth A. Bergey Filamentous algae are often visible on the carapaces of freshwater turtles and these algae are dominated by a few species with varying geographic distributions. Compared to filamentous algae, little is known about the much more speciose microalgae on turtles. Our objectives were to compare the diatom flora [...]
Elizabeth A. Bergey, Joshua T. Cooper, Curtis R. Tackett Diatoms are a major food source for aquatic grazing snails and insects, thereby contributing to aquatic food webs. Diatoms are microscopic and are seldom visible; an exception is colonies of Didymosphenia geminata. Didymosphenia secrete long extracellular stalks that can form mats several centimeters thick. [...]
Elizabeth A. Bergey, Nina Desianti & Joshua T. Cooper Regulated rivers are novel ecosystems with altered temperature and flow regimes that can be used to test distribution patterns of microscopic organisms, such as diatoms. Our objective was to describe the spatial and seasonal patterns of diatoms in a cold-water, oligotrophic river within [...]
Lalit K. Pandey, Elizabeth A. Bergey, Jie Lyu, Jihae Park, Soyeon Choi, Hojun Lee, Stephen Depuydt, Young-Tae Oh, Sung-Mo Lee, Taejun Han Diatoms are regularly used for bioassessment and ecotoxicological studies in relation to environmental and anthropogenic disturbances. Traditional taxonomical diatom parameters (cell counts, biovolume estimates, species richness, diversity indices and metrics [...]
Hussan Gill, Kyler Rogers, Bilal Rehman, John Moynihan, Elizabeth A. Bergey Cigarette butts are a common form of litter that is often deposited on soil, where toxins from butts may affect soil-dwelling organisms. We examined possible toxicity of cigarette butts to the woodland snail Anguispira alternata using a toxicity study with cigarette [...]
Theodore J. Zenzal Jr, Andrea J. Contina, Jeffrey F. Kelly and Frank R. Moore Autumn latitudinal migrations generally exhibit one of two different temporal migration patterns: type 1 where southern populations migrate south before northern populations, or type 2 where northern populations overtake southern populations en route. The ruby-throated hummingbird (Archilochus colubris) is [...]

Jeff Kelly, Joel Strong, Jesse Bahm, and Adrienne Lee Cooper As part of its biological inventory program the National Park Service (NPS) contracted with the Oklahoma Natural Heritage Inventory to conduct a formal and comprehensive mammal, bird, and herpetological inventory of Chickasaw National Recreation Area (CNRA), Oklahoma. The objective of the inventory was [...]
