Nitrogen is often a limiting nutrient for agricultural crops. Most microbes also require an external fixed-nitrogen source for optimal growth. Even for microbes capable of biological nitrogen fixation (BNF), it is generally the case that they will regulate their metabolism to prioritize assimilation of fixed-nitrogen. Microbes employ various strategies and pathways to take advantage of available fixed-nitrogen compounds found...
Age‐based life‐history information provides a foundation for evaluating population dynamics and vulnerability of coral reef fishes, yet many commercially important species from the tropical western Pacific remain poorly characterized. In this study, we examined the age, growth, and reproductive life histories of three reef‐associated species harvested in Guam's commercial fishery: the blacktip grouper Epinephelus fasciatus , t...
Dispersal Propensity and Dispersal Distance Are Genetically Independent Traits in a Stream SalamanderNARA Subscribed
Empirical understanding of dispersal evolution is limited, due in large part to the complexity of the dispersal process and the difficulty of quantifying dispersal directly. To move ahead, it may help to focus on universal dispersal traits: propensity—the discrete emigration response distinguishing dispersers from non‐dispersers—and distance. In particular, little is known about the evolution of dispersal distance, including w...
Length‐Based Spawning Potential Ratio Assessment of Key Species From a Remote Recreational Fishery at Diego Garcia, Indian OceanNARA Subscribed
Recreational fisheries in remote regions often operate under limited regulation and data availability, presenting challenges for sustainable management. Diego Garcia, located within the Chagos Marine Protected Area, hosts a unique recreational reef fishery embedded within a highly protected environment. We assessed the stock status of five key species— Lutjanus bohar , L. gibbus , L. monostigma , Caranx melampygus , and Variol...
Continental‐wide prioritization of protected areas to address global and habitat‐specific goals for avian biodiversity conservationNARA Subscribed
The United Nations and European Union have set ambitious conservation goals to halt and reverse declines in biodiversity by protecting 30% of land and sea areas by 2030. Effective conservation planning requires evidence‐based spatial prioritization to maximize the coverage of species within designated protected areas. Based on a pan‐European database for occurrence and abundance of breeding birds collected in the 2010s, we app...
SNAPSHOT USA 2024: Year 6 of the Coordinated National Camera Trap Survey of the United StatesNARA Subscribed
Motivation SNAPSHOT USA is an annual, multi‐contributor camera trap survey of mammals across the United States. The growing SNAPSHOT USA dataset is intended for tracking the spatial and temporal responses of mammal populations to changes in land use, land cover and climate. These data will be useful for exploring the drivers of spatial and temporal changes in relative abundance and distribution, as well as the impacts of speci...
Climate change threatens biodiversity when species cannot tolerate, adapt to, or track shifting environmental conditions to stay within their climatic niches. A major unresolved question is whether and how species' genetic diversity modulates these dynamics, buffering against range contractions or facilitating range expansions. To test this, we integrated the largest global databases of species range shifts and genetic diversi...
Decomposition of plant litter, facilitated primarily by microbial decomposers, plays a critical role in biogeochemical cycling and ecosystem function. The rate of litter decomposition can determine its environmental impact, where accelerated decomposition alters the timing and rate of nutrient release and may promote nutrient leaching, whereas slowed decomposition can result in litter accumulation, which impacts seedling recru...
