Abstract As atmospheric CO 2 increases, ecosystem carbon sequestration will largely depend on how global changes in climate alter the balance between net primary production and decomposition. The response of to climatic change has been examined using well‐validated mechanistic models, but same is not true for decomposition, a source . We used Long‐term Intersite Decomposition Experiment Team (LIDET) dataset model‐selection techniques choose parameterize model that describes patterns litter...
Abstract Drylands cover 40% of the global terrestrial surface and provide important ecosystem services. While drylands as a whole are expected to increase in extent aridity coming decades, temperature precipitation forecasts vary by latitude geographic region suggesting different trajectories for tropical, subtropical, temperate drylands. Uncertainty future tropical subtropical is well constrained, whereas soil moisture ecological droughts, which drive vegetation productivity composition,...
Landscape connectivity is crucial for many ecological processes, including dispersal, gene flow, demographic rescue, and movement in response to climate change. As a result, governmental non-governmental organizations are focusing efforts map conserve areas that facilitate maintain population promote adaptation. In contrast, little focus has been placed on identifying barriers—landscape features which impede between ecologically important areas—where restoration could most improve...
Drylands occur worldwide and are particularly vulnerable to climate change because dryland ecosystems depend directly on soil water availability that may become increasingly limited as temperatures rise. Climate will both impact plant biomass, with resulting indirect feedbacks moisture. Thus, the net of direct effects moisture requires better understanding. We used ecohydrological simulation model SOILWAT at sites from temperate around globe disentangle contributions additional indirect,...
Repeated perturbations, both biotic and abiotic, can lead to fundamental changes in the nature of ecosystems, including state. Sagebrush steppe communities provide important habitat for wildlife grazing livestock. Fire is an integral part these systems, but there concern that increased ignition frequencies invasive species are fundamentally altering them. Despite issues, majority studies fire effects systems dominated by Artemisia tridentata wyomingensis have focused on single burns. The...
The distribution of rainfed agriculture, which accounts for approximately ¾ global croplands, is expected to respond climate change and human population growth these responses may be especially pronounced in water limited areas. Because the environmental conditions that support agriculture are determined by climate, weather, soil affect overall transient availability, predicting this response has proven difficult, temperate regions much world's agriculture. Here, we show suitability dryland...
The challenges facing the Intermountain West are characterized by extreme complexity and enormous consequences. They include climate change associated ecological effects, such as catastrophic wildfire drought. also inextricably linked to social inequities, including freshwater availability, land conversion, access basic human needs quality food, affordable energy, healthcare. A meaningful response these requires new thinking. Convergent research is designed foster thinking creating novel...
Data-driven decision support can help guide sustainable grazing management by providing an accurate estimate of capacity, in coproduction with managers. Here, we described the development a model to capacity and illustrated its application on two sites western United States. For Montgomery Pass Wild Horse Territory California Nevada, upper limit estimated assessment was 398 horses current population 654 horses. Eagle Creek watershed Apache–Sitgreaves National Forest eastern Arizona, lower...
Disturbances such as fire play a key role in controlling ecosystem structure. In fire-prone forests, organic detritus comprises large pool of carbon and can control the frequency intensity fire. The ponderosa pine forests Colorado Front Range, USA, where has been suppressed for century, provide an ideal system studying long-term dynamics detrital pools. Our objectives were (1) to quantify temporal pools; (2) determine what extent present stand structure, topography, soils constrain these...
Systematic conservation planning efforts typically focus on protecting current patterns of biodiversity. Climate change is poised to shift species distributions, reshuffle communities, and alter ecosystem functioning. In such a dynamic environment, lands selected protect today's biodiversity may fail do so in the future. One proposed approach designing reserve networks that are robust climate involves diversity abiotic conditions part determine distributions ecological processes. A set...
Abstract Aligning water supply with demand is a challenge, particularly in areas large seasonal variation precipitation and those dominated by winter precipitation. Climate change expected to exacerbate this increasing the need for long‐term planning. Long‐term projections of that can aid planning are mostly published as agency reports, which directly relevant decision‐making but less likely inform future research. We present 20‐year Columbia River, produced partnership Washington State...
Abstract Water relations in plant communities are influenced both by contrasting functional groups (grasses and shrubs) climate change via complex effects on interception, uptake, transpiration. We modeled the of group replacement biomass increase, which can be outcomes invasion vegetation management, ecological drought (soil water potential below photosynthesis stops) 340 semiarid grassland sites over 30 year periods. Relative to control (climate site‐determined mixes groups), frequency...
Rangeland-based livestock raising is the only agricultural production system that maintains native plant communities, providing ecosystem services in same space as food and fiber production. Annual aboveground net primary productivity (ANPP) underlies forage multiple services. ANPP highly variable rangelands western United States, across landscape, from year to year, within a growing season. Variability also increasing climate changes. Grazing management decisions determine when, where, how...

In order for agricultural systems to successfully mitigate and adapt climate change there is a need coordinate prioritize next steps research extension. This includes focusing on "win-win" management practices that simultaneously provide short-term benefits farmers improve the sustainability resiliency of with respect change.

Communication theory suggests that interactive dialog rather than information transmission is necessary for climate change action, especially complex systems like agriculture. Climate analogs-locations whose current similar to a target location's future climate-have garnered recent interest as transmitting more relatable information; however, they have unexplored potential in facilitating meaningful dialogs, and whether the way analogs are developed could make difference. We context-specific...
