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

Animal 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

Distance of movement in three threatened butterfly species

Ecological Entomology, Volume 51, Issue 2, Page 250-260, April 2026.
Multi‐year mark–recapture analysis using net displacement and Cormack–Jolly–Seber models shows similar daily detectability (0.17–0.22) among species, supporting robust interspecific comparisons. Dispersal kernels differ: lognormal best for Euphydryas aurinia and Parnassius apollo, exponential for Phengaris arion; P.

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

, 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.,

Population Demographics of Killer Whales (Orcinus orca) in Western Australia

Marine Mammal Science, Volume 42, Issue 2, April 2026.
ABSTRACT Understanding population demographics is crucial for the effective conservation of species. This is particularly important for apex predators, such as the killer whale (Orcinus orca), which play important roles in maintaining the structure and function of ecosystems. In this study, we used capture‐mark‐recapture (CMR) modeling to assess killer

Anthropogenic and Environmental Factors Influence Kentish Plover (Anarhynchus alexandrinus) Survival in a Conservation-Reliant Coastal Population

Birds
Bird survival is influenced by both natural and anthropogenic factors, including weather conditions and oil spills. In this study, we examined the impact of a major oil spill (Prestige oil tanker) and climatic conditions (precipitation and wind) on ...

Population dynamics of a long‐lived pitviper inferred from capture–recapture data spanning four decades

Ecosphere, Volume 17, Issue 3, March 2026.
Abstract Long‐term studies of plant and animal populations are rare, particularly for long‐lived species with slow life histories. However, such studies are necessary to understand how population dynamics are affected by variation in vital rates. We used a large capture–recapture dataset spanning four decades (1983–2019) to estimate several population ...

Recapture heterogeneity in cliff swallows: increased exposure to mist nets leads to net avoidance. [PDF]

PLoS ONE, 2013

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

, 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.

Three decades of western sandpiper stopover dynamics during northward migration on the Pacific Coast of North America, 1992–2022

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
Shorebirds typically spend more time fueling and refueling during migration than they spend in actual flight, and consequently their stopover ecology has important implications for fitness and conservation. We examined spatial variation and long‐term changes in stopover duration of radio‐tagged western sandpipers Calidris mauri over three decades on ...

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.
