A spatial capture-recapture model to estimate fish survival and location from linear continuous monitoring arrays
Joshua K. Raabe, Beth Gardner, Joseph E. Hightower
2013, Canadian Journal of Fisheries and Aquatic Sciences (71) 120-130
We developed a spatial capture–recapture model to evaluate survival and activity centres (i.e., mean locations) of tagged individuals detected along a linear array. Our spatially explicit version of the Cormack–Jolly–Seber model, analyzed using a Bayesian framework, correlates movement between periods and can incorporate environmental or other covariates. We demonstrate the...

Mapping risk for nest predation on a barrier island
Amanda D. Hackney, Robert F. Baldwin, Patrick G.R. Jodice
2013, Journal of Coastal Conservation (17) 615-621
Barrier islands and coastal beach systems provide nesting habitat for marine and estuarine turtles. Densely settled coastal areas may subsidize nest predators. Our purpose was to inform conservation by providing a greater understanding of habitat-based risk factors for nest predation, for an estuarine turtle. We expected that habitat conditions at...

Ashton F. Flinders, Garrett Ito, Michael O. Garcia, John M. Sinton, Jim Kauahikaua, Brian Taylor
2013, Geophysical Research Letters (40) 3367-3373
The Hawaiian Islands are the most geologically studied hot-spot islands in the world yet surprisingly, the only large-scale compilation of marine and land gravity data is more than 45 years old. Early surveys served as reconnaissance studies only, and detailed analyses of the crustal-density structure have been limited. Here we present...
