Spring ecosystems in arid regions often serve as crucial biodiversity hotspots by providing some of the only reliable sources of surface water. However, anthropogenic activities and climate change have severely degraded spring ecosystems worldwide, emphasizing the need for large‐scale multidisciplinary studies informing conservation efforts. Here, we analyzed characteristics of 1121 widely dispersed springs within the Great Ba...
The Toxicology Investigators Consortium 2024 Annual ReportNARA Subscribed
Land use change threatens global biodiversity and compromises ecosystem functions, including pollination and food production. Reduced taxonomic α‐diversity is often reported under land use change, yet the impacts could be different at larger spatial scales (i.e., γ‐diversity), either due to reduced β‐diversity amplifying diversity loss or increased β‐diversity dampening diversity loss. Additionally, studies often focus on taxo...

Are novel or locally adapted pathogens more devastating and why? Resolving opposing hypothesesNARA Subscribed
There is a rich literature highlighting that pathogens are generally better adapted to infect local than novel hosts, and a separate seemingly contradictory literature indicating that novel pathogens pose the greatest threat to biodiversity and public health. Here, using Batrachochytrium dendrobatidis , the fungus associated with worldwide amphibian declines, we test the hypothesis that there is enough variance in “novel” (qua...
Quota use in mixed‐stock fisheriesNARA Subscribed
Although most fisheries assessment and management focuses on the status of individual stocks, and regulations are commonly established as single‐species total allowable catch limits (TACs), much of the catch from global fisheries comes from mixed‐stock fisheries where species cannot be harvested separately. We show that in some fisheries where TAC and catch of demersal fish stocks are tracked, the average fraction of TAC harve...
Global change is impacting forests worldwide, threatening biodiversity and ecosystem services including climate regulation. Understanding how forests respond is critical to forest conservation and climate protection. This review describes an international network of 59 long‐term forest dynamics research sites ( CTFS ‐Forest GEO ) useful for characterizing forest responses to global change. Within very large plots (median size...
Forest Landscapes: Their Effect on the Interaction of the Southern Pine Beetle and Red-Cockaded WoodpeckerNARA Subscribed
The nature of the interaction of the southern pine beetle and red-cockaded woodpecker was investigated using spatially explicit information on the structure of a forest landscape mosaic and knowledge of the behavior of the two organisms. This interaction is the basis for defining functional heterogeneity--how an organism perceives and responds to the elements forming the landscape. Implications for forest landscape management...
