Resource managers need effective methods to limit the spread of invasive Asian carps (Hypophthalmichthys spp.) into new areas. This study evaluated carbon dioxide (CO2) as a barrier and deterrent...

Monitoring rangelands by identifying the departure of contemporary conditions from long-term ecological potential allows for the disentanglement of natural biophysical gradients driving change...
-
Impacts of dreissenid mussels (Dreissena spp.) on Great Lakes ecosystems are well documented, and a better understanding of mechanisms that cause variation in mussel abundance is needed. An...

The data release presents observations of riparian vegetation, topography, and sediment quality in five river reaches of the Lower Virgin River extending downstream 62 river kilometers (rkm), from...
-
Here, we present changes in greater sage-grouse nesting habitat suitability that represents habitat before a simulated fire event and post-fire event after simulating the planting of sagebrush....
