The Value of Native Plants and Local Production in an Era of Global Agriculture
For addressing potential food shortages, a fundamental tradeoff exists between investing more resources to increasing productivity of existing crops, as opposed to increasing crop diversity by incorporating more species. ...
Ecological Consequences of Climate Change on Rangelands
Climate change science predicts warming and greater climatic variability for the foreseeable future. These changes in climate, together with direct effects of increased atmospheric CO2 concentration on plant growth and ...
Geography of current and future global mammal extinction risk
Identifying which species are at greatest risk, what makes them vulnerable, and where they are distributed are central goals for conservation science. While knowledge of which factors influence extinction risk is increasingly ...
Rain or snow: hydrologic processes, observations, prediction, and research needs
The phase of precipitation when it reaches the ground is a first-order driver of hydrologic processes in a watershed. The presence of snow, rain, or mixed-phase precipitation affects the initial and boundary conditions ...
Climatic and geographic predictors of life history variation in Eastern Massasauga (Sistrurus catenatus): A range-wide synthesis
Elucidating how life history traits vary geographically is important to understanding variation in population dynamics. Because many aspects of ectotherm life history are climate-dependent, geographic variation in climate ...
Topographically driven differences in energy and water constrain climatic control on forest carbon sequestration
Mountains are vital to ecosystems and human society given their influence on global carbon and water cycles. Yet the extent to which topography regulates montane forest carbon uptake and storage remains poorly understood. ...
Variable respiration rates of incubated permafrost soil extracts from the Kolyma River lowlands, north-east Siberia
Thawing permafrost supplies dissolved organic carbon (DOC) to aquatic systems
Interacting effects of climate and landscape physiography on pinon pine growth using an individual-based approach
Forest and woodland ecosystems play a crucial role in the global carbon cycle and may be strongly affected by changing climate. Here, we use an individual-based approach to model pinon pine (Pinus edulis) radial growth ...
Poor transferability of a distribution model for a widespread coastal marsh bird in the southeastern United States
Species distribution models have been applied across a wide range of spatial scales to generate information for conservation planning. Understanding how well models transfer through space and time is important to promote ...
Necklace-style radio-transmitters are associated with changes in display vocalizations of male greater sage-grouse
Radio-transmitters are used widely in wildlife research because they allow researchers to track individual animals and monitor their activity. However, to provide unbiased information about a population, transmitters must ...
