Unnatural selection of salmon life histories in a modified riverscape

Anna M. Sturrock, Stephanie M. Carlson, John D. Wikert, Tim Heyne, Sébastien Nusslé, Joseph E. Merz, Hugh J. W. Sturrock & Rachel C. Johnson
Altered river flows and fragmented habitats often simplify riverine communities and favor non‐native fishes, but their influence on life‐history expression and survival is less clear. Here, we quantify the expression and ultimate success of diverse salmon emigration behaviors in an anthropogenically altered California river system. We analyzed two decades of Chinook salmon monitoring data to explore the influence of regulated flows on juvenile emigration phenology, abundance, and recruitment. We then followed seven cohorts into adulthood...

Data from: Mesopredators change temporal activity in response to a recolonizing apex predator

Carolyn R. Shores, Justin A. Dellinger, Eric S. Newkirk, Shannon M. Kachel & Aaron J. Wirsing
Apex predators can influence ecosystems through density and behaviorally mediated effects on herbivores and mesopredators. In many parts of the world, apex predators live in, or are returning to, landscapes that have been modified by people, so it is important to understand their ecological role in anthropogenic landscapes. We used motion-activated game cameras to compare the activity patterns of humans and two mesopredators, coyotes (Canis latrans) and bobcats (Lynx rufus), in areas with and without...
