Effects of Simulated Drought on Yellowcheek Darter (Nothonotus moorei) and Yoke Darter (Nothonotus juliae) Growth, Survival, and Refuge-use, 2024 Dataset Effects of Simulated Drought on Yellowcheek Darter (Nothonotus moorei) and Yoke Darter (Nothonotus juliae) Growth, Survival, and Refuge-use, 2024 Dataset
We used mesocosms to evaluate the effects of drought on Nothonotus moorei (Yellowcheek Darter) and Nothonotus juliae (Yoke Darter) survival, growth, and behavior. Survival was low and did not differ between treatments. Yoke Darters gained mass in control treatments, whereas Yellowcheek Darters did not differ between treatments. Habitat-use varied between treatment and species, with...
Spatial covariance tracks grassland bird community occupancy in fragmented grasslands Spatial covariance tracks grassland bird community occupancy in fragmented grasslands
Grasslands are an imperiled ecosystem, and grassland bird abundance is declining across North America. One of the strongest drivers for these declines is woody plant encroachment of grasslands. In the Great Plains and Sagebrush biomes of North America, spatial covariance—a remote sensing metric for tracking boundaries between vegetation types—is emerging as a new method to identify and...
