Chronology of reproductive investment determines predation risk aversion in a felid-ungulate system.

Daniel A Crawford, Michael J Cherry, Brian D Kelly, Elina P Garrison, David B Shindle, L Mike Conner, Richard B Chandler, Karl V Miller,

Fear of predators can behaviorally mediate prey population dynamics, particularly when predation risk influences reproductive investment. However, the costs of reproductive investment may mitigate predation risk aversion relative to periods when the link between reproductive output and prey behavior is weaker.We posit that intensity of reproductive investment in ungulates may ...

Altitudinal migration: ecological drivers, knowledge gaps, and conservation implications.

An C Hsiung, W Alice Boyle, Robert J Cooper, Richard B Chandler,

Animal migration has been the subject of intensive research for more than a century, but most research has focused on long-distance rather than short-distance migration. Altitudinal migration is a form of short-distance migration in which individuals perform seasonal elevational movements. Despite its geographic and taxonomic ubiquity, there is relatively little ...

Estimating population extinction thresholds with categorical classification trees for Louisiana black bears.

Jared S Laufenberg, Joseph D Clark, Richard B Chandler,

Monitoring vulnerable species is critical for their conservation. Thresholds or tipping points are commonly used to indicate when populations become vulnerable to extinction and to trigger changes in conservation actions. However, quantitative methods to determine such thresholds have not been well explored. The Louisiana black bear (Ursus americanus luteolus) was ... Read more >>

Spatial Capture-Recapture for Categorically Marked Populations with An Application to Genetic Capture-Recapture

Ben Augustine, Andrew Royle, Sean Murphy, Richard Chandler, John Cox, Marcella Kelly,

Abstract Recently introduced unmarked spatial capture-recapture (SCR), spatial mark-resight (SMR), and 2-flank spatial partial identity models (SPIM) extend the domain of SCR to populations or observation systems that do not always allow for individual identity to be determined with certainty. For example, some species do not have natural marks that ... Read more >>

Spatial occupancy models for predicting metapopulation dynamics and viability following reintroduction

Richard B Chandler, Erin Muths, Brent H Sigafus, Cecil R Schwalbe, Christopher J Jarchow, Blake R Hossack, Jörg Müller,

The reintroduction of a species into its historic range is a critical component of conservation programmes designed to restore extirpated metapopulations. However, many reintroduction efforts fail, and the lack of rigorous monitoring programmes and statistical models have prevented a general understanding of the factors affecting metapopulation viability following reintroduction. Spatially ... Read more >>

An open-population hierarchical distance sampling model.

Rahel Sollmann, Beth Gardner, Richard B Chandler, J Andrew Royle, T Scott Sillett,

Modeling population dynamics while accounting for imperfect detection is essential to monitoring programs. Distance sampling allows estimating population size while accounting for imperfect detection, but existing methods do not allow for estimation of demographic parameters. We develop a model that uses temporal correlation in abundance arising from underlying population dynamics ... Read more >>

Inferences about population dynamics from count data using multistate models: a comparison to capture-recapture approaches.

Elise F Zipkin, T Scott Sillett, Evan H Campbell Grant, Richard B Chandler, J Andrew Royle,

Wildlife populations consist of individuals that contribute disproportionately to growth and viability. Understanding a population's spatial and temporal dynamics requires estimates of abundance and demographic rates that account for this heterogeneity. Estimating these quantities can be difficult, requiring years of intensive data collection. Often, this is accomplished through the capture ... Read more >>

Hierarchical distance-sampling models to estimate population size and habitat-specific abundance of an island endemic.

T Scott Sillett, Richard B Chandler, J Andrew Royle, Marc Kery, Scott A Morrison,

Population size and habitat-specific abundance estimates are essential for conservation management. A major impediment to obtaining such estimates is that few statistical models are able to simultaneously account for both spatial variation in abundance and heterogeneity in detection probability, and still be amenable to large-scale applications. The hierarchical distance-sampling model ... Read more >>
