Many large mammalian carnivores are facing population declines due to illegal killing (e.g., shooting) and habitat modification (e.g., livestock farming). Illegal killing occurs cryptically and hence is difficult to detect. However, reducing illegal killing requires a solid understanding of its magnitude and underlying drivers, while accounting for the imperfect...

Jason T. Bracken, Amelie Y. Davis, Katherine M. O’Donnell, William Barichivich, Susan C. Walls, Tereza Jezkova
2022, Ecosphere (13)
Occurrence data used to build species distribution models often include historical records from locations in which the species no longer exists. When these records are paired with contemporary environmental values that no longer represent the conditions the species experienced, the model creates false associations that hurt predictive performance. The extent...

Significant gaps remain in understanding the response of plant reproduction to environmental change. This is partly because measuring reproduction in long-lived plants requires direct observation over many years and such datasets have rarely been made publicly available. Here we introduce MASTREE+, a data set that collates reproductive time-series data from...
Variation in foraging patterns as reflected by floral resources used by male vs female bees of selected species at Badlands National Park, SD
Diane L. Larson, Zachary M. Portman, Jennifer Larson, Deborah A. Buhl
2022, Arthropod-Plant Interactions (16) 145-157
Female and male bees forage for different reasons: females provision nests with pollen appropriate for larval development and consume nectar for energy while males need only fuel their own energetic requirements. The expectation, therefore, is that females should visit fewer floral resource species than males, due to females’ focus...
