Wildlife Monographs, Volume 218, Issue 1, September 2025.We found variable spatial and temporal patterns and predictability of plant phenological progression across 8 pronghorn ranges in Montana. We sampled potential exposure to phenology values for migrants and residents along spring movement paths and summer ranges and found that within herds and years the resident and migrant movement strategies conferred

Biotropica, Volume 57, Issue 5, September 2025.Spotted hyenas (Crocuta crocuta) are known to range across broad savanna regions of sub‐Saharan Africa, but there is very limited understanding of how and to what extent they use lowland rainforest habitats. We use camera trap data and GPS telemetry to show that bais, natural rainforest clearings, can support hyenas living exclusively in the rainforest—

Journal of Advances in Modeling Earth Systems, Volume 17, Issue 8, August 2025.Abstract A new cirrus cloud parameterization for the ICOLMDZ atmospheric general circulation model (AGCM) is presented. Prognostic equations for cloud fraction, ice water content and cloudy water vapor are introduced, and the processes that affect these quantities are parameterized.
