Annual survival estimation of migratory songbirds confounded by incomplete breeding site-fidelity: study designs that may help [PDF]

open access: yesAnimal Biodiversity and Conservation, 2004
Many species of bird exhibit varying degrees of site–fidelity to the previous year’s territory or breeding area, a phenomenon we refer to as incomplete breeding site–fidelity. If the territory they occupy is located beyond the bounds of the study area or

Trap‐dependence in capture–recapture studies: empirical evidence in vertebrates and biological meaning

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Capture–recapture (CR) models have been used for decades to estimate population size and demographic rates in natural populations from the monitoring of individuals. One of the most frequent deviations from assumptions required in CR studies is the immediate trap‐dependence that corresponds to the correlation between capture events. We review empirical

Estimating survival probabilities from ringing data [PDF]

open access: yes, 2012
Die Ermittlung von Überlebenswahrscheinlichkeiten und Reproduktionsdaten hat eine wachsende Bedeutung als Basis für Populationsmodelle gewonnen. Wir haben Beringungen und Rückmeldungen aus dem Datenbestand der Beringungszentrale Hiddensee und die ...

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]

open access: yes, 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.

Survival Rates and Capture Heterogeneity of Bottlenose Dolphins (Tursiops truncatus) in the Shannon Estuary, Ireland

open access: yesFrontiers in Marine Science, 2021
Adult survival is arguably the most important demographic parameter for long-lived species as it has a large impact on population growth, and it can be estimated for cetacean populations using natural markings and mark-recapture (MR) modelling.

Probit models for capture-recapture data subject to imperfect detection, individual heterogeneity and misidentification [PDF]

open access: yes, 2014
As noninvasive sampling techniques for animal populations have become more popular, there has been increasing interest in the development of capture-recapture models that can accommodate both imperfect detection and misidentification of individuals (e.g.,

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

open access: yesJournal 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 ...

Bumblebee family lineage survival is enhanced in high quality landscapes [PDF]

open access: yes, 2017
Insect pollinators such as bumblebees (Bombus spp.) are in global decline1,2, a major cause of which is habitat loss due to agricultural intensification3.
