Demography and site fidelity of a grassland bird, the Henslow's Sparrow, in powerline right-of-way habitat

Journal of Field Ornithology, 2022
Grassland birds are among the fastest declining avian species in North America, primarily due to habitat loss. In the southeastern United States, much grassland and open savanna habitat has been converted to timber production or agriculture, neither of ...

Age-specific survival of male Golden-cheeked Warblers on the Fort Hood Military Reservation, Texas

Avian Conservation and Ecology, 2014
Population models are essential components of large-scale conservation and management plans for the federally endangered Golden-cheeked Warbler (Setophaga chrysoparia; hereafter GCWA). However, existing models are based on vital rate estimates calculated

Methodological advances [PDF]

Animal Biodiversity and Conservation, 2004
The study of population dynamics has long depended on methodological progress. Among many striking examples, continuous time models for populations structured in age (Sharpe & Lotka, 1911) were made possible by progress in the mathematics of integral ...

Group heterogeneity in the Jolly-Seber-Tag-Loss model

, 2014
Mark–recapture experiments involve capturing individuals from populations of interest, marking and releasing them at an initial sample time, and recapturing individuals from the same populations on subsequent occasions.

Population ecology and the management of whale watching operations on a data‐deficient dolphin population

Ecology and Evolution, 2019
Whale watching is a popular commercial activity, producing socio‐ecological benefits but also potential long‐term effects on the targeted cetacean population.

The Jolly-Seber-Tag-Loss model with group heterogeneity

, 1969
Mark-recapture experiments are performed to estimate population parameters such as survival probabilities. Animals are captured, tagged, released, and recaptured at subsequent time periods in order to obtain parameter information.

Hierarchial mark-recapture models: a framework for inference about demographic processes

Animal Biodiversity and Conservation, 2015
The development of sophisticated mark-recapture models over the last four decades has provided fundamental tools for the study of wildlife populations, allowing reliable inference about population sizes and demographic rates based on clearly formulated ...

Survival of fallen and returned rooftop nesting Least Tern chicks

Avian Conservation and Ecology
Beach habitat is increasingly degraded and disturbed, and many species of Larids (gulls, terns, and skimmers) have adapted to nesting on gravel rooftops.
