The USGS and the Smithsonian Institution have initiated the first in situ active aboveground and belowground warming experiment in a coastal wetland that is focused on wetland temperature responses and also examines the interaction between warming, elevated CO2, and inundation frequency on wetland resilience in the face of changes in global change drivers.

Plants and insects comprise a large portion of problematic invasive species. The success of these invasions largely depends on the outcomes of plant-insect interactions in which plants that escape herbivores may be more successful invaders, and herbivores that find adequate hosts have the opportunity to establish. This project will explore the dynamics of introduced plant or insect populations, or

Relict forests are becoming more common as as climates become hotter, drier and more saline. The first sign of threat to these forests is a chronic lack of seedling and sapling recruitment. This project will help pinpoint forests at risk to help in future management.

Spend a summer on the shore of Lake Michigan, investigating the role that dynamic dune disturbance and successional processes play in the spatial metapopulation dynamics of Pitcher’s thistle, a federally threatened plant. This project will provide a basis for developing spatial population models that can indicate the present and future conditions for the species in the Great Lakes.

Want to conduct collaborative eco-geomorphic research at the forefront of climate change impacts? We have a novel landscape-scale ecosystem experiment, using two adjacent tidal rivers with a 9x difference in watershed sediment loads, to determine how sediment availability regulates the resilience or loss of tidal freshwater wetlands as the result of sea level rise and salinization.

Exploring for the critical platinum-group elements (PGEs) relies upon understanding the geophysical signature of the entire magmatic system in which they form, from bottom to top. The USGS is applying a range of geophysical techniques to investigate the internal architecture of layered mafic intrusions.

Molecular methods such as quantitative polymerase chain reaction (qPCR) allow scientists the ability to target specific genes allowing for a rapid, sensitive, and cost-effective way to determine the presence and relative abundance of potential pathogen genes in the environment. Although there are many benefits to qPCR such as not relying on the ability to culture fastidious microorganisms ...

The need for better models and more effective use of data to characterize river corridor transport processes is keenly felt, from evaluating the effectiveness of river and watershed management practices all the way to clarifying regulatory authority under the Clean Water Act.

We are looking for a student to join our multi-disciplinary and multi-institution team exploring the relationships between energy development and air quality in the southwestern U.S. This research provides an exceptional opportunity for students to explore the complexities of land use and ecosystem function, as well as experience the diverse work environments found within the federal government.

Shifts in phenology provide one of the strongest indicators of an organism’s adaptive capacity to climate change, yet it is one of the most poorly known consequences of future impacts. This project seeks to improve understanding and develop adaptation strategies of the effects of phenological shifts and trophic mismatches in Atlantic coastal fish, seabird and marine mammal species.
