Quantifying the effect of semi-natural riparian cover on stream temperatures: implications for salmonid habitat management: Previous studies examining the effects of riparian cover on stream temperatures have led to highly variable findings. In an attempt to reduce these uncertainties, this study examines the relationship between stream temperature variability and local climatic conditions over discrete 300-m sections of a watercourse. Seventeen stream sections were chosen within the Slaney catchment on the basis of riparian cover and size. Continuous monitoring over a 2-year period from May 2010 found that riparian cover had a measurable cooling effect on water temperatures at small spatial scales. The magnitude of this effect was dependent on stream size and local climactic conditions.

Ranking Site Vulnerability to Increasing Temperatures in Southern Appalachian Brook Trout Streams in Virginia: An Exposure - Sensitivity Approach: Climate change vulnerability classification model for brook trout populations; brook trout populations are classified into one of four quadrants based on direct measurements or model predictions of sensitivity and exposure. Low exposure, low sensitivity populations are most likely to persist under various climate change scenarios.

Removal of Two Dams in the Wetmore Run Watershed, PA_FY12 Project: As part of a plan to upgrade their public water supply to a non-dam alternative, the Borough of Galeton agreed to remove two dams and their associated impoundments. The dams were located on Wetmore Run and Right Branch of Wetmore Run, Potter County, PA. Both streams are classified as High Quality – Coldwater Fishery (HQ – CWF) by the Pennsylvania Department of Environmental Protection (PA DEP) and drain a predominantly forested watershed comprised of ~60% public land. The barriers blocked upstream Brook Trout passage to approximately 8.5 miles of headwater habitat, contributed to the elevation of instream temperatures, interrupted the natural flow regime, and negatively impacted ecosystem function. As a result of the dam removals, almost 8.5 miles of headwater habitat was reconnected to the rest of the upper Pine Creek Watershed, which contains several intact eastern Brook Trout populations.

Response of fish assemblages to declining acidic deposition in Adirondack Mountain lakes, 1984-2012: Adverse effects of acidic deposition on the chemistry and fish communities were evident in Adirondack Mountain lakes during the 1980s and 1990s. Fish assemblages and water chemistry in 43 Adirondack Long-Term Monitoring (ALTM) lakes were sampled by the Adirondack Lakes Survey Corporation and the New York State Department of Environmental Conservation during three periods (1984-87, 1994-2005, and 2008-12) to document regional impacts and potential biological recovery associated with the 1990 amendments to the 1963 Clean Air Act (CAA). We assessed standardized data from 43 lakes sampled during the three periods to quantify the response of fish-community richness, total fish abundance, and brook trout (Salvelinus fontinalis) abundance to declining acidity that resulted from changes in U.S. airquality management between 1984 and 2012. During the 28-year period, mean acid neutralizing capacity (ANC) increased significantly from 3 to 30 meq/L and mean inorganic monomeric Al concentrations decreased significantly from 2.22 to 0.66 mmol/L, yet mean species richness, all species or total catch per net night (CPNN), and brook trout CPNN did not change significantly in the 43 lakes. Regression analyses indicate that fishery metrics were not directly related to the degree of chemical recovery and that brook trout CPNN may actually have declined with increasing ANC. While the richness of fish communities increased with increasing ANC as anticipated in several Adirondack lakes, observed improvements in water quality associated with the CAA have generally failed to produce detectable shifts in fish assemblages within a large number of ALTM lakes. Additional time may simply be needed for biological recovery to progress, or else more proactive efforts may be necessary to restore natural fish assemblages in Adirondack lakes in which water chemistry is steadily recovering from acidification.
