Seasonality Structures Avian Functional Diversity and Niche Packing Across North AmericaNARA Subscribed
Assemblages in seasonal ecosystems undergo striking changes in species composition and diversity across the annual cycle. Despite a long‐standing recognition that seasonality structures biogeographic gradients in taxonomic diversity (e.g., species richness), our understanding of how seasonality structures other aspects of biodiversity (e.g., functional diversity) has lagged. Integrating seasonal species distributions with comp...
Topographic information improves simulated patterns of post‐fire conifer regeneration in the southwest United StatesNARA Subscribed
The western United States is projected to experience more frequent and severe wildfires in the future due to drier and hotter climate conditions, exacerbating destructive wildfire impacts on forest ecosystems such as tree mortality and unsuccessful post‐fire regeneration. While empirical studies have revealed strong relationships between topographical information and plant regeneration, ecological processes in ecosystem models...
Winter conditions structure extratropical patterns of species richness of amphibians, birds and mammals globallyNARA Subscribed
Aim The aim was to derive global indices of winter conditions and examine their relationships with species richness patterns outside of the tropics. Location All extratropical areas (>25° N and 25° S latitudes), excluding islands. Time period 2000–2018. Major taxa studied Amphibians, birds and mammals. Methods We mapped three global indices of winter conditions [number of days of frozen ground (length of frozen ground winter);...
Sediment Trapping by Streamside Management Zones of Various Widths after Forest Harvest and Site PreparationNARA Subscribed
Recommended widths for streamside management zones (SMZs) for sediment protection vary. The objectives of this study were to compare the effects of SMZ widths and thinning levels on sediment moving through SMZs. Four SMZ treatments were installed within 16 harvested watersheds where intermittent streams graded into small perennial streams. Sites were clearcut, prescribed burned, and planted with loblolly pine (Pinus taeda L.)....
