Full Proposal - A Stream Classification System for the Appalachian Landscape Conservation Cooperative
-
The goal of this project is to develop a hierarchical classification for stream and river systems within the Appalachian Landscape Conservation Cooperative (LCC). This classification system will identify and consistently map ecologically similar types of rivers and streams using a flexible hierarchical set of geomorphic and hydrologic variables deemed appropriate for classification by the participating states and relevant to the spatial scale of management.

Full Proposal - A Web-Based Tool for Riparian Restoration Prioritization to Promote Climate Change Resilience (RPCCR) in Eastern U.S. Streams
-
The RPCCR is a web-based tool currently under development which is designed to allow managers to rapidly identify high-priority riparian restoration targets. The objective of this project is to complete development of the RPCCR, link it with the Appalachian LCC website, and integrate it with ongoing stream temperature monitoring and modeling efforts within the Northeast Climate Science Center (NECSC) and participating Landscape Conservation Cooperatives.

Global separation of plant transpiration from groundwater and streamflow
-
Current land surface models assume that groundwater, streamflow and plant transpiration are all sourced and mediated by the same well mixed water reservoir—the soil. However, recent work in Oregon1 and Mexico2 has shown evidence of ecohydrological sepa- ration, whereby different subsurface compartmentalized pools of water supply either plant transpiration fluxes or the combined fluxes of groundwater and streamflow. These findings have not yet been widely tested. Here we use hydrogen and oxygen isotopic data (2H/1H (d2H) and 18O/16O (d18O)) from 47 globally distrib- uted sites to show that ecohydrological separation is widespread across different biomes. Precipitation, stream water and ground- water from each site plot approximately along the d2H/d18O slope of local precipitation inputs. But soil and plant xylem waters extracted from the 47 sites all plot below the local stream water and groundwater on the meteoric water line, suggesting that plants use soil water that does not itself contribute to groundwater recharge or streamflow. Our results further show that, at 80% of the sites, the precipitation that supplies groundwater recharge and streamflow is different from the water that supplies parts of soil water recharge and plant transpiration. The ubiquity of subsurface water compartmentalization found here, and the segregation of storm types relative to hydrological and ecological fluxes, may be used to improve numerical simulations of runoff generation, stream water transit time and evaporation–transpiration partitioning. Future land surface model parameterizations should be closely examined for how vegetation, groundwater recharge and streamflow are assumed to be coupled.

Haywood Waterways Kids in the Creek
-
Kids in the Creek was created by the Tennessee Valley Authority and brought to Haywood County in 1997. The purpose is to expose 8th grade students to hands-on activities that raise awareness of the importance of clean water and the issues that could degrade water quality. The students rotate among four stations: the EnviroScape watershed model, water chemistry, fish, and benthic macroinvertebrates. At the fish station, the students collect data for a classroom exercise that ties everything together.

Human mining activity across the ages determines the genetic structure of modern brown trout (Salmo trutta L.) populations
-
Humans have exploited the earth’s metal resources for thousands of years leaving behind a legacy of toxic metal contamination and poor water quality. The southwest of England provides a well-defined example, with a rich history of metal mining dating to the Bronze Age. Mine water washout continues to negatively impact water quality across the region where brown trout (Salmo trutta L.) populations exist in both metal-impacted and relatively clean rivers. We used micro- satellites to assess the genetic impact of mining practices on trout populations in this region. Our analyses demonstrated that metal-impacted trout populations have low genetic diversity and have experienced severe population declines. Metal-river trout populations are genetically distinct from clean-river populations, and also from one another, despite being geographically proximate. Using approximate Bayesian computation (ABC), we dated the origins of these genetic patterns to periods of intensive mining activity. The historical split of contemporary metal-impacted populations from clean-river fish dated to the Medieval period. Moreover, we observed two distinct genetic populations of trout within a single catchment and dated their divergence to the Industrial Revolution. Our investigation thus provides an evaluation of contemporary population genetics in showing how human-altered landscapes can change the genetic makeup of a species.

Increasing Northern Hemisphere water deficit
-
A monthly water-balance model is used with CRUTS3.1 gridded monthly precip- itation and potential evapotranspiration (PET) data to examine changes in global water deficit (PET minus actual evapotranspiration) for the Northern Hemisphere (NH) for the years 1905 through 2009. Results show that NH deficit increased dramatically near the year 2000 during both the cool (October through March) and warm (April through September) seasons. The increase in water deficit near 2000 coincides with a substantial increase in NH temperature and PET. The most pronounced increases in deficit occurred for the latitudinal band from 0 to 40°N. These results indicate that global warming has increased the water deficit in the NH and that the increase since 2000 is unprecedented for the 1905 through 2009 period. Additionally, coincident with the increase in deficit near 2000, mean NH runoff also increased due to increases in P. We explain the apparent contradiction of concurrent increases in deficit and increases in runoff.
