Temporal Variation in Adult Survival Rates of Roseate Terns During Periods of Increasing and Declining Populations (2008)

Jeffrey A. Spendelow, James E. Hines, James D. Nichols, Grace Cormons, Helen Hays, ...

We used 19 years of mark-recapture/resighting data collected on 11,020 birds from 1988-2006 at five colony sites in Massachusetts, New York, and Connecticut, USA, to examine temporal variation in the...

Population Dynamics of the Concho Water Snake in Rivers and Reservoirs (2008)

Martin J. Whiting, James R. Dixon, Brian D. Greene, James M. Mueller, Jeff S. Hatfield, ...

The Concho Water Snake (Nerodia harteri paucimaculata) is confined to the Concho–Colorado River valley of central Texas, thereby occupying one of the smallest geographic ranges of any North...

Making Great Leaps Forward: Accounting for Detectability in Herpetological Field Studies (2007)

Marc J. Mazerolle, Larissa L. Bailey, William L. Kendall, J. Andrew Royle, Sarah J. Converse, James D. Nichols

Detecting individuals of amphibian and reptile species can be a daunting task. Detection can be hindered by various factors such as cryptic behavior, color patterns, or observer experience. These...

ON THE ESTIMATION OF DISPERSAL AND MOVEMENT OF BIRDS (2004)

William L. Kendall, James D. Nichols

The estimation of dispersal and movement is important to evolutionary and population ecologists, as well as to wildlife managers. We review statistical methodology available to estimate movement...

Sources of variation in breeding-ground fidelity of mallards (Anas platyrhynchos) (2002)

Doherty, Paul F., Nichols, James D., Tautin, John, Voelzer, James F., Smith, Graham W., Benning, Douglas S., ...

Generalizations used to support hypotheses about the evolution of fidelity to breeding areas in birds include the tendency for fidelity to be greater in adult birds than in yearlings. In ducks, in...

Migration, Harvest, and Population Characteristics of Mourning Doves Banded in the Western Management Unit, 1964-1977. (1997)

Tomlinson, Roy E., Dolton, David D., Reeves, Henry M., Nichols, James D., McKibben, Laurence A.

A nationwide banding program for mourning doves (Zenaida macroura) was conducted cooperatively by State wildlife agencies and the U.S. Fish and Wildlife Service during 1967-1975. Banding and recovery...

Higher temporal variability of forest breeding bird communities in fragmented landscapes

Boulinier, Thierry, Nichols, James D., Hines, James E., Sauer, John R., Flather, Curtis H., Pollock, Kenneth H.

Understanding the relationship between animal community dynamics and landscape structure has become a priority for biodiversity conservation. In particular, predicting the effects of habitat...

Sexual selection affects local extinction and turnover in bird communities

Doherty, Paul F., Sorci, Gabriele, Royle, J. Andrew, Hines, James E., Nichols, James D., Boulinier, Thierry

Predicting extinction risks has become a central goal for conservation and evolutionary biologists interested in population and community dynamics. Several factors have been put forward to explain...

Tigers and their prey: Predicting carnivore densities from prey abundance

Karanth, K. Ullas, Nichols, James D., Kumar, N. Samba, Link, William A., Hines, James E.

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 resources...

Spatio-temporal dynamics of species richness in coastal fish communities.

Lekve, Kyrre, Boulinier, Thierry, Stenseth, Nils Chr, Gjøsaeter, Jakob, Fromentin, Jean-Marc, Hines, James E, ...

Determining patterns of change in species richness and the processes underlying the dynamics of biodiversity are of key interest within the field of ecology, but few studies have investigated the...

The use of resighting data to estimate the rate of population growth of the snail kite in Florida

Victoria J. Dreitz, James D. Nichols, James E. Hines, Robert E. Bennetts, Wiley M. Kitchens, Donald L. Deangelis

The rate of population growth (λ) is an important demographic parameter used to assess the viability of a population and to develop management and conservation agendas. We examined the use of...

Investigations of potential bias in the estimation of λ using Pradel's (1996) model for capture-recapture data

James E. Hines, James D. Nichols

Pradel's (1996) temporal symmetry model permitting direct estimation and modelling of population growth rate, λ i , provides a potentially useful tool for the study of population dynamics using...

Modelling postfledging survival and age-specific breeding probabilities in species with delayed maturity: a case study of Roseate Terns at Falkner Island, Connecticut

Jeffrey A. Spendelow, James D. Nichols, James E. Hines, Jean-Dominique Lebreton, Roger Pradel

We modelled postfledging survival and age-specific breeding probabilities in endangered Roseate Terns ( Sterna dougallii ) at Falkner Island, Connecticut, USA using capture-recapture data from...

Approaches for the direct estimation of λ, and demographic contributions to λ, using capture-recapture data

James D. Nichols, James E. Hines

We first consider the estimation of the finite rate of population increase or population growth rate, λ i , using capture-recapture data from open populations. We review estimation and modelling of...
