ESTIMATING SITE OCCUPANCY RATES WHEN DETECTION PROBABILITIES ARE LESS THAN ONE
Nondetection of a species at a site does not imply that the species is absent unless the probability of detection is 1. We propose a model and likelihood-based method for estimating site occupancyExpand

ESTIMATING SITE OCCUPANCY, COLONIZATION, AND LOCAL EXTINCTION WHEN A SPECIES IS DETECTED IMPERFECTLY
Few species are likely to be so evident that they will always be detected when present. Failing to allow for the possibility that a target species was present, but undetected, at a site will lead toExpand

ESTIMATION OF TIGER DENSITIES IN INDIA USING PHOTOGRAPHIC CAPTURES AND RECAPTURES
The tiger (Panthera tigris) is an endangered, large felid whose demographic status is poorly known across its distributional range in Asia. Previously applied methods for estimating tiger abundance,Expand

ESTIMATING ABUNDANCE FROM REPEATED PRESENCE–ABSENCE DATA OR POINT COUNTS
We describe an approach for estimating occupancy rate or the proportion of area occupied when heterogeneity in detection probability exists as a result of variation in abundance of the organism underExpand

ESTIMATING TEMPORARY EMIGRATION USING CAPTURE-RECAPTURE DATA WITH POLLOCK'S ROBUST DESIGN
TLDR
We present a likelihood- based approach to dealing with temporary emigration that permits estimation under different models of temporary emigrants and yields tests for completely random and Markovian emigration. Expand

CAPTURE-RECAPTURE SURVIVAL MODELS TAKING ACCOUNT OF TRANSIENTS
TLDR
The presence of transient animals, common enough in natural populations, invalidates the estimation of survival by traditional capture-recapture (CR) models designed for the study of residents only. Expand

Tigers and their prey: Predicting carnivore densities from prey abundance.
The goal of ecology is to understand interactions that determine the distribution and abundance of organisms. In principle, ecologists should be able to identify a small number of limiting resourcesExpand
