Restoration of the Greater Everglades Ecosystem is guided by the Comprehensive...
Bayesian analysis of multi-state data with individual covariates for estimating genetic effects on demography
Sarah J. Converse, J. Andrew Royle, Richard P. Urbanek
2012, Journal of Ornithology (152) 561-572
Inbreeding depression is frequently a concern of managers interested in restoring endangered species. Decisions to reduce the potential for inbreeding depression by balancing genotypic contributions to reintroduced populations may exact a cost on long-term demographic performance of the population if those decisions result in reduced numbers of animals released and/or...
Assessment of toxicity and potential risk of the anticoagulant rodenticide diphacinone using Eastern screech-owls (Megascops asio)
Barnett A. Rattner, Katherine E. Horak, Rebecca S. Lazarus, Karen M. Eisenreich, Carol U. Meteyer, Steven F. Volker, Christopher M. Campton, John D. Eisemann, John J. Johnston
2012, Ecotoxicology (21) 832-846
In the United States, new regulatory restrictions have been placed on the use of some second-generation anticoagulant rodenticides. This action may be offset by expanded use of first-generation compounds (e.g., diphacinone; DPN). Single-day acute oral exposure of adult Eastern screech-owls (Megascops asio) to DPN evoked overt signs of intoxication, coagulopathy,...
Combining lake and watershed characteristics with Landsat TM data for remote estimation of regional lake clarity
Ian M. McCullough, Cyndy Loftin, Steven A. Sader
2012, Remote Sensing of Environment (123) 109-115
Water clarity is a reliable indicator of lake productivity and an ideal metric of regional water quality. Clarity is an indicator of other water quality variables including chlorophyll-a, total phosphorus and trophic status; however, unlike these metrics, clarity can be accurately and efficiently estimated remotely on a regional scale. Remote...
