Broader impacts for ecologists: Biological soil crust as a model system for education Broader impacts for ecologists: Biological soil crust as a model system for education
Biological soil crusts (biocrusts) are a complex community of algae, cyanobacteria, lichens, bryophytes, and assorted bacteria, fungi, archaea, and bacteriophages that colonize the soil surface. Biocrusts are particularly common in drylands and are found in arid and semiarid ecosystems worldwide. While diminutive in size, biocrusts often cover large terrestrial areas, provide numerous...

Drivers of realized satellite tracking duration in marine turtles Drivers of realized satellite tracking duration in marine turtles
Background Satellite tags have revolutionized our understanding of marine animal movements. However, tags may stop transmitting for many reasons and little research has rigorously examined tag failure. Using a long-term, large-scale, multi-species dataset, we evaluated factors influencing tracking duration of satellite tags to inform study design for future tracking studies. Methods We...

Juvenile Chinook salmon survival, travel time, and floodplain use relative to riverine channels in the Sacramento–San Joaquin River Delta Juvenile Chinook salmon survival, travel time, and floodplain use relative to riverine channels in the Sacramento–San Joaquin River Delta
Floodplains provide multiple benefits to both resident and migratory fish species, including juvenile Chinook Salmon Oncorhynchus tshawytscha, but direct comparisons of survival during migration through a floodplain versus riverine routes are scarce. The Yolo Bypass is a broad floodplain of the Sacramento River that floods in about 30% of years in response to large, uncontrolled runoff...

Accelerometry to study fine-scale activity of invasive Burmese pythons (Python bivittatus) in the wild Accelerometry to study fine-scale activity of invasive Burmese pythons (Python bivittatus) in the wild
The establishment of Burmese pythons (Python bivittatus) in Everglades National Park, Florida, USA, has been connected to a > 90% decline in the mesomammal population in the park and is a major threat to native reptile and bird populations. Efforts to control this population are underway, but are hampered by a lack of information about fine-scale activity cycles and ecology of these...

Testing which axes of species differentiation underlie covariance of phylogeographic similarity among montane sedge species Testing which axes of species differentiation underlie covariance of phylogeographic similarity among montane sedge species
Co‐distributed species may exhibit similar phylogeographic patterns due to shared environmental factors or discordant patterns attributed to the influence of species‐specific traits. Although either concordant or discordant patterns could occur due to chance, stark differences in key traits (e.g., dispersal ability) may readily explain differences between species. Multiple species’...

Behaviorally-mediated trophic cascade attenuated by prey use of risky places at safe times Behaviorally-mediated trophic cascade attenuated by prey use of risky places at safe times
The mere threat of predation may incite behavioral changes in prey that lead to community-wide impacts on productivity, biodiversity, and nutrient cycling. The paucity of experimental manipulations, however, has contributed to controversy over the strength of this pathway in wide-ranging vertebrate systems. We investigated whether simulated gray wolf (Canis lupus) presence can induce...

Yellowstone grizzly bear investigations 2020 - Annual report of the Interagency Grizzly Bear Study Team Yellowstone grizzly bear investigations 2020 - Annual report of the Interagency Grizzly Bear Study Team
This Annual Report summarizes results of grizzly bear (Ursus arctos) research and monitoring conducted in the Greater Yellowstone Ecosystem (GYE) by the Interagency Grizzly Bear Study Team (IGBST) during 2020. The research and monitoring program is focused on population estimation and demographics, food monitoring, and habitat monitoring. This report also presents a summary of grizzly...
