Combining tangential flow filtration and size fractionation of mesocosm water as a method for the investigation of waterborne coral diseases
James S. Evans, Valerie J. Paul, Blake Ushijima, Christina A. Kellogg
2022, Biology Methods and Protocols (7)
The causative agents of most coral diseases today remain unknown, complicating disease response and restoration efforts. Pathogen identifications can be hampered by complex microbial communities naturally associated with corals and seawater, which create complicating “background noise” that can potentially obscure a pathogen’s signal. Here, we outline an approach to investigate...

Simona Picardi, Peter S. Coates, Jesse L. Kolar, Shawn T. O’Neil, Steven R. Mathews, David K. Dahlgren
Annabel Smith, editor(s)
2022, Journal of Applied Ecology (59) 624-635
Post-release monitoring of translocated animals is often used to inform future translocation protocols. Quantifying habitat selection of translocated individuals may help identify features that characterize good settlement habitat and thus inform the choice of future release sites. However, translocated animals often undergo post-release behavioural modification, and their habitat selection...

Lindsay Reynolds, Laura Perry, Patrick B. Shafroth, Gabrielle L. Katz, Andrew S. Norton
2022, Wetlands (42) 1-23
Riparian ecosystems in the western USA have been invaded by non-native woody species deliberately introduced for stream bank stabilization, agricultural windbreaks, and urban shade. Recent work suggests that the non-native tree Ulmus pumila (Siberian elm) is capable of significant spread in western riparian ecosystems, that range infilling is still incomplete, and that...
Daily foraging activity of an imperiled ground squirrel: Effects of hibernation, thermal environment, body condition, and conspecific density
Austin A Z. Allison, Courtney J. Conway
2022, Behavioral Ecology and Sociobiology (76)
Food acquisition is among the most important tasks faced by free-ranging animals. Predation and thermal risks, however, can make foraging a costly endeavor and foraging can preclude other important activities. Moreover, seasonal life cycle events such as hibernation impose energetic thresholds and time constraints on foraging. These factors interact with...
