Toxicity, sublethal effects, and potential modes of action of select fungicides on freshwater fish and invertebrates
Adria A. Elskus
2012, Open-File Report 2012-1213
Despite decades of agricultural and urban use of fungicides and widespread detection of these pesticides in surface waters, relatively few data are available on the effects of fungicides on fish and invertebrates in the aquatic environment. Nine fungicides are reviewed in this report: azoxystrobin, boscalid, chlorothalonil, fludioxonil, myclobutanil, fenarimol, pyraclostrobin,...

Estimation of baseline daily mean streamflows for ungaged locations on Pennsylvania streams, water years 1960-2008
Marla H. Stuckey, Edward H. Koerkle, James E. Ulrich
2012, Scientific Investigations Report 2012-5142
Water-resource managers use daily mean streamflows to generate streamflow statistics and analyze streamflow conditions. An in-depth evaluation of flow regimes to promote instream ecological health often requires streamflow information obtainable only from a time series hydrograph. Historically, it has been difficult to estimate daily mean streamflow for an ungaged location....

Charles B. Yackulic, Janice Reid, Raymond Davis, James E. Hines, James D. Nichols, Eric Forsman
2012, Ecology (93) 1953-1966
In this paper, we modify dynamic occupancy models developed for detection-nondetection data to allow for the dependence of local vital rates on neighborhood occupancy, where neighborhood is defined very flexibly. Such dependence of occupancy dynamics on the status of a relevant neighborhood is pervasive, yet frequently ignored. Our framework permits...
