Severe droughts cause widespread tree mortality and decreased growth in forests across the globe. Forest managers are seeking strategies to increase forest resistance (minimizing negative impacts during the drought) and resilience (maximizing recovery rates following drought). Limited experimental evidence suggests that forests with particular structural characteristics have greater capacity to resist change and or recover ecosystem function in the face of drought. However, the applicability of these results to practical forest conservation and management remains unclear. This project utilized an existing network of eight long-term, operational-scale, forest management experiments from Arizona to Maine to examine...
America’s remaining grassland in the Prairie Pothole Region (PPR) is at risk of being lost to crop production. When crop prices are high, like the historically high corn prices that the U.S. experienced between 2008 and 2014, the risk of grassland conversion is even higher. Changing climate will add uncertainties to any efforts toward conservation of grassland in the PPR. Grassland conversion to cropland in the region would imperil nesting waterfowl among other species and further impair water quality in the Mississippi watershed. In this project, we sought to contribute to the understanding of land conversion in the PPR with the aim to better target the use of public and private funds allocated toward incentivizing...
Understanding of the influence of global warming has been limited by a paucity of experiments. Taking advantage of the largest, longest-running experimental warming of a forest, we convened dozens of scientists from across the world to collect data to study and understand how bacteria, fungi, herbivores, plant pathogens, insects and a diversity of other groups respond to warming. We found that warming had a significant impact on ecosystems at both a site in North Carolina, as well as a more northern site in Massachusetts. The types of effects, however, differed between the north and south; they also differed as a function of the organisms considered. While warming affected all levels of organization, it had the...
Rates of climate and land use change vary across the Great Plains and Rocky Mountains as do the responses of ecosystems to these changes. Knowledge of locations of rapid land use and climate change and changes in ecosystem services such as water runoff and ecological productivity are important for vulnerability assessment and crafting locally relevant adaptation strategies to cope with these changes. This project assessed the loss of public, private, and tribal lands due to ongoing land use intensifications and fragmentation extents across the NC CSC domain. In addition, the project evaluated how the climate, ecosystem processes, and vegetation have shifted over the past half century and how they are projected to...

In California, increased wildfire activity has been linked to decreasing snowpack and earlier snowmelt. Not only has this translated into a longer fire season, but reduced snowpack has cascading effects that impact streamflow, water supplies, agricultural productivity, and ecosystems. California receives 80% of its precipitation during the winter, so mountain snowpack plays a critical role in replenishing the state’s water supply. One factor that affects the amount of winter precipitation (and therefore snowpack) in California is the North Pacific Jet (NPJ)—a current of strong, high altitude winds that occur over the northern Pacific Ocean. Winters when the NPJ is located further north than normal are drier than...

Natural climate variability can obscure or enhance long-term trends in experienced weather due to climate change. This can happen temporarily on timescales of a season to several years to a decade or two. Natural variability is poorly described and attributed to specific causes, contributing to uncertainty and misunderstandings about the nature of climate change that stakeholders and resource managers attempt to anticipate. There exists, therefore, a need to clarify the magnitude and causality of natural climate variability. This connection needs to be explained for locally-experienced weather and particularly for daily extreme events, whose seasonal behavior impacts both resources and imagination. Conversely, it...
With the extensive loss and fragmentation of most native habitats, connectivity has become increasingly important for sustaining wildlife populations and communities. Connectivity can be defined as the extent to which the landscape facilitates or impedes the movement of organisms among patches of habitat. The goal of this project was to evaluate terrestrial connectivity across the South Central United States. We addressed this goal using a variety of approaches, including evaluating connectivity of major habitats (grasslands and forests), predicting future changes in landscape connectivity for grassland species under future land-use change scenarios, assessing terrestrial vertebrate diversity in relation to habitat...
