Statistical inference for capture-recapture experiments Statistical inference for capture-recapture experiments
This monograph presents a detailed, practical exposition on the design, analysis, and interpretation of capture-recapture studies. The Lincoln-Petersen model (Chapter 2) and the closed population models (Chapter 3) are presented only briefly because these models have been covered in detail elsewhere. The Jolly- Seber open population model, which is central to the monograph, is covered in...

Modeling and the management of migratory birds Modeling and the management of migratory birds
Mathematical modeling of migratory bird populations is reviewed in the context of migratory bird management. We focus on dynamic models of waterfowl, since most management-oriented migratory bird models concern waterfowl species. We describe the management context for these modeling efforts, with a focus on large-scale operational data collection programs and on processes by which...

American woodcock winter distribution and fidelity to wintering areas American woodcock winter distribution and fidelity to wintering areas
We examined winter distribution and fidelity to wintering areas for the American Woodcock (Scolopax minor), which exhibits reversed, sexual size dimorphism. Band-recovery data revealed no difference in winter distributions of different age/sex classes for woodcock from the same breeding ares. Similarly, band recoveries from woodcock banded on wintering grounds revealed no difference in...

Capture-recapture estimation of prebreeding survival rate for birds exhibiting delayed maturation Capture-recapture estimation of prebreeding survival rate for birds exhibiting delayed maturation
Many species of seabirds exhibit delayed maturity and do not return to the natal colony to breed for several years after fledging. Capture-recapture studies are frequently conducted at such breeding colonies and often include marking of young birds. However, because of the absence of these birds from the natal colony during the first few years after banding, the data do not fit neatly...

Effects of tillage practices and carbofuran exposure on small mammals Effects of tillage practices and carbofuran exposure on small mammals
We compared population estimates, body mass, movement, and blood chemistry of small mammals between conventionally tilled and no-till cornfields in Maryland and Pennsylvania to evaluate the effects of tillage practices and carbofuran exposure on small mammals. Estimates suggest that populations of white-footed mice (Peromyscus leucopus) were not significantly related (P > 0.05) to...
