Dragonflies at a Biogeographical Crossroads: The Odonata of Oklahoma and Complexities Beyond its Borders

Brenda D. Smith and Michael A. Patten From the Publisher's Website: This lavishly illustrated book examines the distribution, ecology, conservation status, and biogeography of 176 species of dragonflies in the southern plains of the United States, where twelve ecoregions converge. The topics discussed, such as phenotypic variation and ecology, are applicable and of interest across [...]

Predicting the distributions of regional endemic dragonflies using a combined model approach

Wade A. Boys, Adam M. Siepielski, Brenda D. Smith, Michael A. Patten, and Jason T. Bried Insect Conservation and Diversity doi: 10.1111/icad.12444 Climate warming is predicted to have large effects on insects, yet several data shortfalls, including distributional information, impede effective conservation strategies. Knowledge of species distributions is a critical component for assessing conservation need [...]

Geographic variation in a restricted-range endemic dragonfly Gomphurus ozarkensis (Odonata: Gomphidae), with description of a new subspecies

Michael A. Patten, Alexandra A. Barnard, and Brenda D. Smith Journal of Insect Biodiversity 13(2):15–26. . doi: The geographic distribution of Gomphurus ozarkensis (Westfall, 1975), a species described to science only four decades ago, is confined to a four-state area in the central United States: southeastern Kansas, eastern Oklahoma, western and northern Arkansas, and [...]

Breeding thresholds in opportunistic Odonata records

Michael A. Patten, Emily A. Hjalmarson, Brenda D. Smith-Patten, and Jason T. Bried Ecological Indicators 106(2019) DOI: Numerous interacting abiotic and biotic factors shape an organism's spatial distribution, and these factors vary spatially and temporally, such that habitat used for breeding may differ from habitat used at other times of the life cycle. We [...]

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 [...]
