Stress-responsiveness influences baseline glucocorticoid levels: Revisiting the under 3 min sampling rule

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, [...]

Diatoms on the carapace of common snapping turtles: Luticola spp. dominate despite spatial variation in assemblages

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 [...]

Occurrence of the Invasive Diatom Didymosphenia geminata in Southeast Oklahoma

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. [...]

Characterization of the diatom flora in the Lower Mountain Fork (Oklahoma, USA), a novel regulated river with a disjunct population of the diatom Didymosphenia geminata (Bacillariophyta)

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 [...]

The use of diatoms in ecotoxicology and bioassessment: Insights, advances and challenges

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 [...]

Cigarette butts may have low toxicity to soil-dwelling invertebrates: Evidence from a land snail

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 [...]

Temporal migration patterns between natal locations of ruby-throated hummingbirds (Archilochus colubris) and their Gulf Coast stopover site

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 [...]
