Changes in sources and storage in a karst aquifer during a transition from drought to wet conditions
C.I. Wong, B.J. Mahler, M. Musgrove, J.L. Banner
2012, Journal of Hydrology (468-469) 159-172
Understanding the sources and processes that control groundwater compositions and the timing and magnitude of groundwater vulnerability to potential surface-water contamination under varying meteorologic conditions is critical to informing groundwater protection policies and practices. This is especially true in karst terrains, where infiltrating surface water can rapidly affect groundwater quality....

2012, Conservation Biology (26) 873-882
Climate change will likely have profound effects on cold-water species of freshwater fishes. As temperatures rise, cold-water fish distributions may shift and contract in response. Predicting the effects of projected stream warming in stream networks is complicated by the generally poor correlation between water temperature and air temperature. Spatial dependencies...

Neighborhood and habitat effects on vital rates: expansion of the Barred Owl in the Oregon Coast Ranges
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...
