Rising atmospheric CO2 reduces nitrogen availability in boreal forests Rising atmospheric CO2 reduces nitrogen availability in boreal forests
Anthropogenic nitrogen (N) pollution has been emphasized as a cause of eutrophication globally. However, several recent datasets have suggested widespread oligotrophication may be occurring in some ecosystems, which is suggested to be a response to rising atmospheric carbon dioxide (eCO2). Plant δ15N chronologies have served as primary evidence for oligotrophication, however, there has...

Overestimated natural biological nitrogen fixation translates to an exaggerated CO2 fertilization effect in Earth System Models Overestimated natural biological nitrogen fixation translates to an exaggerated CO2 fertilization effect in Earth System Models
CO2 fertilization of the terrestrial biosphere is limited by nitrogen. Biological nitrogen fixation (BNF) is the dominant natural nitrogen source to the terrestrial biosphere and can alleviate nitrogen limitation but is poorly constrained in Earth system models (ESMs). Here, we compare terrestrial BNF from an ensemble of ESMs of the 6th Coupled Model Intercomparison Project to a new...

Local adaptation to climate has facilitated the global invasion of cheatgrass Local adaptation to climate has facilitated the global invasion of cheatgrass
Local adaptation may facilitate range expansion during invasions, but the mechanisms promoting destructive invasions remain unclear. Cheatgrass (Bromus tectorum), native to Eurasia and Africa, has invaded globally, with particularly severe impacts in western North America. We aimed to identify mechanisms and consequences of local adaptation in the North American cheatgrass invasion. We...

Aridity reduces lag times between aquatic and terrestrial dry-down among watersheds and across years in the northwest US Aridity reduces lag times between aquatic and terrestrial dry-down among watersheds and across years in the northwest US
Landscapes encompass both aquatic and terrestrial ecosystems that experience the same climate but may respond to climate in divergent ways. For example, the time lag between seasonal dry-down of terrestrial soil moisture and decline in streamflow has important implications for species and ecosystem processes across the aquatic–terrestrial interface. How these lags between aquatic and...

Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease Amphibian diversity of the western Colorado canyonlands including potential threats from nonnative bullfrogs and disease
Throughout the canyons of the Colorado and Uncompahgre Plateaus, water is a limited resource for wildlife, with patchy distribution and seasonal availability. Tributary creeks within these canyons drain into mainstem rivers, providing habitat and breeding sites for native amphibians. Yet, little is known about the diversity and distribution of amphibians that live in these harsh, dynamic

Environmental drivers of Greater Sage-grouse population trends over 25 years in Idaho, USA Environmental drivers of Greater Sage-grouse population trends over 25 years in Idaho, USA
Greater Sage-grouse (Centrocercus urophasianus) populations have been in decline for decades across much of the US Intermountain West. However, findings from 25 years of lek counts in Idaho indicate that some populations are stable or even increasing. After accounting for potential biases in past lek count data, we sought to explain the variability in population trends among all 70 lek...

Field test of the self-preserving eDNA filter and the importance of calibration when changing methods during long-term monitoring Field test of the self-preserving eDNA filter and the importance of calibration when changing methods during long-term monitoring
Filtering water is currently the primary field method used for collecting aquatic environmental DNA (eDNA). One of the drawbacks of filtering is the need to transfer the filter from the filter housing to a preservative-filled container in the field. New products are being developed to avoid this handling step, but comparative studies are needed to ensure that the results produced by new...

Movements and habitat use vary across the Rocky Mountain Population of trumpeter swans Movements and habitat use vary across the Rocky Mountain Population of trumpeter swans
The Rocky Mountain Population (RMP) of trumpeter swans Cygnus buccinator (hereafter, swans) in North America includes breeders in the Greater Yellowstone Area (GYA) and other western states (together, United States segment) and western provinces of Canada (Canada segment). Conservation concern for the United States segment stems from its slow population growth and the resident nature of...

Landscape changes and declines in Aquila chrysaetos (Golden Eagle) territory occupancy in southwestern Idaho Landscape changes and declines in Aquila chrysaetos (Golden Eagle) territory occupancy in southwestern Idaho
Rapid loss of native shrubs and expansion of invasive annual plants like cheatgrass (Bromus tectorum) have altered North American shrub-steppe systems across extensive areas. Predators, like Aquila chrysaetos (Golden Eagle) that forage on shrub-reliant prey, may abandon historically occupied territories or increase their territory size to cope with degraded habitat. We used a multiseason...
