Forest cover lessens hurricane impacts on peak streamflow
Jazlynn S. Hall, Martha A. Scholl, James B. Shanley, Serena Matt, Maria Uriarte
2024, Hydrological Processes (38)
Cyclonic storms (i.e., hurricanes) are powerful disturbance events that often cause widespread forest damage. Storm-related canopy damage reduces rainfall interception and evapotranspiration, but impacts on streamflow regimes are poorly understood. We quantify streamflow changes in Puerto Rico following Hurricane Maria in September 2017, and evaluate whether forest cover and storm-related...

Despite regional variation, Gymnorhinus cyanocephalus (Pinyon Jay) densities generally increase with local pinyon–juniper cover and heterogeneous ground cover
Nicholas J. Van Lanen, Adrian P. Monroe, Cameron L. Aldridge
2024, Ornithological Applications (126)
Traditionally, local-scale habitat-relationship models are developed over small spatial extents, limiting model transferability and inference outside the study area. Thus, habitat managers frequently lack fine-scale information regarding the influence of vegetation composition and structure on site suitability or species abundance. Gymnorhinus cyanocephalus (Pinyon Jay) represents one declining species for which managers...
Landscape-scale modeling to forecast fluvial-aeolian sediment connectivity in river valleys
Alan Kasprak, Joel B. Sankey, Joshua Caster
2024, Geophysical Research Letters (51)
Sedimentary landforms on Earth and other planetary bodies are built through scour, transport, and deposition of sediment. Sediment connectivity refers to the hypothesis that pathways of sediment transport do not occur in isolation, but rather are mechanistically linked. In dryland river systems, one such example of sediment connectivity is the transport of...
