Counter‐factual simulation highlights requirements for additional management to avert extinction of a relict Tītī/Sooty Shearwater population

open access: yesIbis, Volume 168, Issue 4, Page 1348-1363, October 2026.
Seabirds play key ecological roles but face increasing threats worldwide. Among them, Tītī (Sooty Shearwater) Ardenna grisea are among the most abundant and culturally significant species in the Southern Hemisphere but are also threatened. Kapiti Island, Aotearoa (New Zealand), holds a Tītī colony which, despite eradication of non‐native mammalian ...

Estimating seasonal survival of migratory birds using continuous‐time capture–recapture models

open access: yesEcological Applications, Volume 36, Issue 6, September 2026.
Abstract Understanding the population dynamics of migratory species requires consideration of their entire annual cycle. A key requirement is the decomposition of annual survival into seasonal periods. While there is increasing evidence that migrations are the most dangerous phase of the annual cycle, temporal variation in seasonal survival and its ...

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

open access: yesScientia 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.

High and minimally variable adult marine survival among multiple stocks of Chinook salmon

open access: yesEcosphere, Volume 17, Issue 9, September 2026.
Abstract Estimates of individual survival across space and time provide critical information on processes that regulate population abundance. Here, we use state‐space models fit to data from more than 500 acoustically tagged Chinook salmon to better understand the factors that shape survival during the final summer and fall of marine residence—a life ...

A generalised likelihood framework for partially observed capture-recapture-recovery models [PDF]

open access: yes, 2013
We provide a closed form likelihood expression for multi-state mark-recapture-recovery data when the state of an individual may be only partially observed.

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

Age‐specific survival of reintroduced swift fox in Badlands National Park and surrounding lands

open access: yesWildlife Society Bulletin, 2016
In 2003, a reintroduction program was initiated at Badlands National Park (BNP), South Dakota, USA, with swift foxes (Vulpes velox) translocated from Colorado and Wyoming, USA, as part of a restoration effort to recover declining swift fox populations ...
