Toby D. Feaster, Anthony J. Gotvald, J. Curtis Weaver
2014, Fact Sheet 2014-3015
Reliable estimates of the magnitude and frequency of floods are essential for the design of transportation and water-conveyance structures, flood insurance studies, and flood-plain management. Flood-frequency estimates are particularly important in densely populated urban areas. The U.S. Geological Survey (USGS) used a multistate approach to update methods for determining the...

Hierarchical spatial capture-recapture models: Modeling population density from stratified populations
J. Andrew Royle, Sarah J. Converse
2014, Methods in Ecology and Evolution (5) 37-43
Capture–recapture studies are often conducted on populations that are stratified by space, time or other factors. In this paper, we develop a Bayesian spatial capture–recapture (SCR) modelling framework for stratified populations – when sampling occurs within multiple distinct spatial and temporal strata.We describe a hierarchical model that integrates...

2014, The Auk (131) 195-207
A growing collection of mtDNA genetic information from waterfowl species across North America suggests that larger-bodied cavity-nesting species exhibit greater levels of population differentiation than smaller-bodied congeners. Although little is known about nest-cavity availability for these species, one hypothesis to explain differences in population structure is reduced dispersal tendency of...
