Rapid butterfly declines across the United States during the 21st century Rapid butterfly declines across the United States during the 21st century

Reports of declining insect populations have received widespread media attention, but evidence for declines has been variable across regions and taxonomic groups. Edwards et al. examined trends in the most surveyed taxon: butterflies (see the Perspective by Inouye). Combining data from 35 citizen science programs across the continental US, the authors found declines in overall butterfly...

Using plant invasions to compare occurrence- and abundance-based calculations of biotic homogenisation: Are results complementary or contradictory? Using plant invasions to compare occurrence- and abundance-based calculations of biotic homogenisation: Are results complementary or contradictory?

Aim Beta diversity quantifies the similarity of ecological assemblages. Its increase, known as biotic homogenisation, can be a consequence of biological invasions. However, species occurrence (presence/absence) and abundance-based analyses can produce contradictory assessments of the magnitude and direction of changes in beta diversity. Previous work indicates these contradictions should...

U.S. Geological Survey Cooperative Research Units Program—A hawk’s view of 2024 U.S. Geological Survey Cooperative Research Units Program—A hawk’s view of 2024

Introduction The U.S. Geological Survey Cooperative Fish and Wildlife Research Units (USGS CRU) program was established in 1935 and codified by Congress in 1960 to enhance graduate education in wildlife and fisheries sciences and to facilitate research and technical assistance among natural resource agencies and universities on fisheries and wildlife management topics of mutual concern...

First documentation of pelagic larvae of Prickly Sculpin Cottus asper in Willamette Basin reservoirs using a novel light trapping method First documentation of pelagic larvae of Prickly Sculpin Cottus asper in Willamette Basin reservoirs using a novel light trapping method

Although sculpin can play important ecological roles, serving as abundant key meso-predators in freshwater aquatic systems, much remains to be learned about their development and ecology. Depth discrete light traps effectively captured larval sculpin from Lookout Point Reservoir in the Willamette Basin, Oregon, USA. We confirm that these larvae were Prickly Sculpin (Cottus asper) based...
