Communicating and Using Uncertain Scientific Information in the Production of ‘Actionable Science’
Conservation practitioners must navigate many challenges to advance effective natural-resource management in the presence of multiple uncertainties. Numerous climatic and ecological changes remain on the horizon, and their eventual consequences are not completely understood. Even so, their influences are expected to impact important resources and the people that depend on them across local, regional, and sometimes global scales. Although forecasts of future conditions are almost always imperfect, decision makers are increasingly expected to communicate and use uncertain information when making policy choices that affect multiple user groups. The degree to which management objectives are met can depend on 1) how critical uncertainties are identified and accounted for, and 2) effective communication among user groups, scientists, and resource managers.
Characterization of spatial and temporal variability in fishes in response to climate change
Predicting population responses to climate change requires an understanding of how population dynamics vary over space and time. For instance, a measured indicator may vary among repeated samples from a single site, from site to site within a lake, from lake to lake, and over time. Although variability has historically been viewed as an impediment to understanding population responses to ecological changes, the structure of variation can also be an important part of the response. In this project, we will build upon recently completed analyses of fish population data in the Great Lakes basin to help predict how spatial and temporal variation in fish populations may respond to climate change and other important drivers.
Bringing people, data, and models together - addressing impacts of climate change on stream temperature
Few previous studies have focused on how climate change may impact headwater systems, despite the importance of these areas for aquatic refugia. The lack of these studies has resulted in the majority of climate impact assessments focusing on conservation of ecological systems at broad levels, and has not focused on turning results into useful and actionable information for managers on the ground. A critical and timely research question is: “What data and modeling frameworks are needed to provide scientists reliable, climate-informed, water temperature estimates for freshwater ecosystems that can assist watershed management decision making?” This research will answer this through two primary activities: 1) gathering and compiling existing stream temperature data within the DOI-Northeast region and subsequent deployment of data loggers to areas where additional data are needed, and 2) an intercomparison of state-of-the-art statistical and deterministic stream temperature models to evaluate their ability to replicate point stream temperature measurements and model scalability to non-gaged sites with the Northeast region.
Assessment of terrestrial and aquatic monitoring programs in the Southeastern United States
A significant challenge faced by climate scientists in the public and private sector is the need for information about the historical status of ecological systems expected to be influenced by climate change. The need is especially acute for reliable and complete information about monitoring networks maintained by government and non-governmental organizations and associated data. While many organizations monitor one or more aspects of aquatic and terrestrial ecosystems, these monitoring programs are seldom coordinated and information about both the networks and the associated data are not readily available. The DOI Southeast Climate Science Center is participating in an effort by multiple federal, state, and other organizations to develop a comprehensive and integrated assessment of monitoring networks associated with atmospheric, stream, and terrestrial ecosystems. The objective of this two-year project is to support the development of this assessment.
Assessing Forest Fragmentation from Marcellus Shale Gas Development
Expansion of drilling sites and associated infrastructure to extract natural gas from the Marcellus shale deposits has the potential to significantly reduce existing forest cover across the Marcellus field and leave what remains in a fragmented state.
Assessing climate-sensitive ecosystems in the southeastern United States
The southeastern U.S. contains a unique diversity of ecosystems that provide important benefits, including habitat for wildlife and plants, water quality, and recreation opportunities. As climate changes, a better understanding of how our ecosystems will be affected is vital for identifying strategies to protect these ecosystems. While information on climate change affects exists for some ecosystems and some places, a synthesis of this information for key ecosystems across the entire Southeast will enable regional decision-makers, including the LCCs, to prioritize current efforts and plan future research and monitoring.
Synthesis of climate model downscaling products for the southeastern United States
Downscaling translates large-scale climate information to the local scale. There are several techniques for handling this process; recently, several downscaled climate products have been produced by government and academic researchers. Ecologists, conservation scientists, and practitioners require such local guidance to evaluate adaptation and conservation strategies. However, the large number of methods involved, different downscaling approaches, resolutions, time periods, and focal variables limits the ability of these users to form meaningful conclusions and evaluate the results of adaptation strategies. To address these issues, this project will summarize the methods used for downscaling, identify the metrics most appropriate for evaluation of climate model skill and usability for the ecological and conservation communities in the southeastern US, and begin a longer-term effort to evaluate the range of downscaled climate products over this geographic region.
Genetics Provide New Hope for Endangered Freshwater Mussels
A piece of the restoration puzzle to save populations of endangered freshwater mussels may have been found, according to a recent U.S. Geological Survey led study. Local population losses in a river may not result in irreversible loss of mussel species; other mussels from within the same river could be used as sources to restore declining populations.

USGS Global Change Monitoring Portal
The Global Change Monitoring Portal (GCMP) is a project of the DOI Southeast Climate Science Center and aims to support the efforts of multiple federal, state, and other organizations by providing a centralized, comprehensive catalog of observational networks associated with aquatic and terrestrial ecosystems in the southeastern United States. The Southeast GCMP region of interest encompasses all or part of several Landscape Conservation Cooperatives (LCCs) in the southeastern US and Caribbean. Information about existing and historical observational networks and monitoring sites was compiled into a relational database. Programs and sites are classified according to: type of media being monitored (air, land, water), the general type of measurements that are made (biological, chemical, physical), and the general type of parameters that are measured (e.g., fauna) within a particular measurement type (e.g., biological).
NOAA National Center for Environmental Information
The National Center for Environmental Information is the world’s largest provider of weather and climate data. Land-based, marine, model, radar, weather balloon, satellite, and paleoclimatic are just a few of the types of datasets available. Detailed descriptions of the available products and platforms are available on the website.
