Invariant polar bear habitat selection during a period of sea ice loss
Ryan H. Wilson, Eric V. Regehr, Karyn D. Rode, Michelle St. Martin
2016, Proceedings of the Royal Society B: Biological Sciences (283)
Climate change is expected to alter many species' habitat. A species' ability to adjust to these changes is partially determined by their ability to adjust habitat selection preferences to new environmental conditions. Sea ice loss has forced polar bears (Ursus maritimus) to spend longer periods annually over less productive waters,...

Donna S. Francy, Amie M.G. Brady, Christopher D. Ecker, Jennifer L. Graham, Erin A. Stelzer, Pamela Struffolino, Keith A. Loftin
2016, Harmful Algae (58) 23-34
Cyanobacterial harmful algal blooms (cyanoHABs) and associated toxins, such as microcystin, are a major global water-quality issue. Water-resource managers need tools to quickly predict when and where toxin-producing cyanoHABs will occur. This could be done by using site-specific models that estimate the potential for elevated toxin concentrations that cause public...

2016, Aeolian Research (22) 93-106
Atmospheric mineral dust can influence climate and biogeochemical cycles. An important component of mineral dust is ferric oxide minerals (hematite and goethite) which have been shown to influence strongly the optical properties of dust plumes and thus affect the radiative forcing of global dust. Here we report on the iron...
Proximate influences on female dispersal in white-tailed deer
Clayton L. Lutz, Duane R. Diefenbach, Christopher S. Rosenberry
2016, Journal of Wildlife Management (80) 1218-1226
Ultimate causes of animal dispersal have been hypothesized to benefit the dispersing individual because dispersal reduces competition for local resources, potential for inbreeding, and competition for breeding partners. However, proximate cues influence important features of dispersal behavior, including when dispersal occurs, how long it lasts, and direction, straightness, and distance...
