Targeted surveillance for highly pathogenic avian influenza in migratory waterfowl across the conterminous United States: chapter 12 Targeted surveillance for highly pathogenic avian influenza in migratory waterfowl across the conterminous United States: chapter 12
Introduction of Asian strain H5N1 Highly Pathogenic avian influenca via waterfowl migration is one potential route of entry into the United States. In conjunction with state, tribe, and laboratory partners, the United States Department of Agriculture collected and tested 124,603 wild bird samples in 2006 as part of a national surveillance effort. A sampling plan was devised to increase...

Monitoring carnivore populations at the landscape scale: occupancy modelling of tigers from sign surveys Monitoring carnivore populations at the landscape scale: occupancy modelling of tigers from sign surveys
1. Assessing spatial distributions of threatened large carnivores at landscape scales poses formidable challenges because of their rarity and elusiveness. As a consequence of logistical constraints, investigators typically rely on sign surveys. Most survey methods, however, do not explicitly address the central problem of imperfect detections of animal signs in the field, leading to...

A Markov decision process for managing habitat for Florida scrub-jays A Markov decision process for managing habitat for Florida scrub-jays
Florida scrub-jays Aphelocoma coerulescens are listed as threatened under the Endangered Species Act due to loss and degradation of scrub habitat. This study concerned the development of an optimal strategy for the restoration and management of scrub habitat at Merritt Island National Wildlife Refuge, which contains one of the few remaining large populations of scrub-jays in Florida...

Demographic consequences of migratory stopover: Linking red knot survival to horseshoe crab spawning abundance Demographic consequences of migratory stopover: Linking red knot survival to horseshoe crab spawning abundance
Understanding how events during one period of the annual cycle carry over to affect survival and other fitness components in other periods is essential to understanding migratory bird demography and conservation needs. Previous research has suggested that western Atlantic red knot (Calidris canutus rufa) populations are greatly affected by horseshoe crab (Limulus polyphemus) egg...

Improving occupancy estimation when two types of observational error occur: Non-detection and species misidentification Improving occupancy estimation when two types of observational error occur: Non-detection and species misidentification
Efforts to draw inferences about species occurrence frequently account for false negatives, the common situation when individuals of a species are not detected even when a site is occupied. However, recent studies suggest the need to also deal with false positives, which occur when species are misidentified so that a species is recorded as detected when a site is unoccupied. Bias in...
