A range‐wide full‐annual‐cycle model informs conservation of a declining migratory shorebird

Journal of Applied Ecology, Volume 63, Issue 1, January 2026.
The tōrea population decline suggests the need for a higher IUCN threat classification and a conservation strategy (e.g. habitat protection and restoration) targeting multiple demographic rates across the annual cycle of tōrea. Our novel approach using population growth rates to link fragmented local, season‐specific data to model range‐wide full ...

Modelos jerárquicos de marcaje–recaptura: un marco para la inferencia de procesos demográficos [PDF]

, 2004
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 ...

The average laboratory samples a population of 7,300 Amazon Mechanical Turk workers [PDF]

, 2015
Using capture-recapture analysis we estimate the effective size of the active Amazon Mechanical Turk (MTurk) population that a typical laboratory can access to be about 7,300 workers.

Survival probabilities of loggerhead sea turtles (Caretta caretta) estimated from capture-mark-recapture data in the Mediterranean Sea

Scientia Marina, 2007
Survival probabilities of loggerhead sea turtles (Caretta caretta) are estimated for the first time in the Mediterranean by analysing 3254 tagging and 134 re-encounter data from this region. Most of these turtles were juveniles found at sea.

Photo-identification and its application to gregarious delphinids: Common dolphins (Delphinus sp.) in the Hauraki Gulf, New Zealand : A thesis submitted in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Marine Ecology at Massey University, Albany, New Zealand [PDF]

, 2016
Common dolphins (Delphinus sp.) remain one of the most poorly understood delphinids within New Zealand waters. Baseline data on their abundance, site fidelity, movement patterns, and social structure remain unknown.

Demography Meets Climate Change: Life History Challenges for a Neotropical Viviparous Lizard

Ecology and Evolution, Volume 15, Issue 12, December 2025.
Considering the current biodiversity crisis, it is crucial to understand the impact of global environmental changes on natural populations. Analyzing demographic parameters from long‐term studies is the most effective approach to uncovering patterns that describe population dynamics.

Similar population dynamics before and after a chytridiomycosis outbreak in a tropical riparian amphibian species

Ecosphere, Volume 16, Issue 12, December 2025.
Abstract Emerging infectious diseases can cause rapid, widespread host mortality, and the lack of demographic data before and after pathogen emergence complicates understanding mechanisms of host persistence. This challenge is further compounded by environmental conditions that influence host behavior, while driving pathogen growth and virulence. These
