Software Review: A program for testing capture-recapture data for closure
Thomas R. Stanley, Jon D. Richards
2005, Wildlife Society Bulletin (33) 782-785
Capture-recapture methods are widely used to estimate population parameters of free-ranging animals. Closed-population capture-recapture models, which assume there are no additions to or losses from the population over the period of study (i.e., the closure assumption), are preferred for population estimation over the open-population models, which do not assume closure,...

G. Mueller
2005, General Information Product 9
Historically, the Colorado River was one of the most formidable rivers in the world. Each spring, melting snow from the mountains scoured the desert landscape moving millions of tons of sediment to the sea. The Grand Canyon lays testament to its erosive nature. Summer heat would bring seasonal droughts, reducing...
Interaction of rearing environment and reproductive tactic on gene expression profiles in Atlantic salmon
N. Aubin-Horth, B.H. Letcher, H.A. Hofmann
2005, Conference Paper, Journal of Heredity
Organisms that share the same genotype can develop into divergent phenotypes, depending on environmental conditions. In Atlantic salmon, young males of the same age can be found either as sneakers or immature males that are future anadromous fish. Just as the organism-level phenotype varies between divergent male developmental trajectories, brain...
