Infectious zoonotic diseases are a threat to wildlife conservation and global health. They are especially a concern for wild apes, which are vulnerable to many human infectious diseases. As ecotourism, deforestation, and great ape field research increase, the threat of human-sourced infections to wild populations becomes more substantial and could...
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...
Impact of fluid-rock interaction on strength and hydraulic transmissivity rvolution in shear fractures under hydrothermal conditions
Tamara Nicole Jeppson, David A. Lockner
2022, Conference Paper, Proceedings, 47th workshop on geothermal reservoir engineering
Reactivated shear fractures contribute to the creation of pervasive fracture networks in geothermal systems. The creation, reactivation, and sustainability of fracture networks depend on complex coupling among thermal, hydraulic, mechanical, and chemical (THMC) processes. However, most laboratory experiments focus either solely on how fluid transport properties evolve in stationary fractures...
