Apparent survival probability and abundance of juvenile green turtles in the foraging ground at Kuroshima Island, Ryukyu Archipelago

Endangered Species Research, 2023
An understanding of the survival probability and abundance of endangered species is critical for their effective conservation and management. In this study, long-term capture-mark-recapture data were used to estimate the apparent survival probability and

Long‐term apparent survival of a cold‐stunned subpopulation of juvenile green turtles

Ecosphere, 2022
Understanding the effects of extreme weather on animal populations is fundamental to ecological and conservation sciences and species management. Climate change has resulted in both warm and cold temperature extremes, including an increased frequency of ...

Demography Meets Climate Change: Life History Challenges for a Neotropical Viviparous Lizard. [PDF]

Ecol Evol
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.

Subterranean systems provide a suitable overwintering habitat for Salamandra salamandra

International Journal of Speleology, 2017
The fire salamander (Salamandra salamandra) has been repeatedly noted to occur in natural and artificial subterranean systems. Despite the obvious connection of this species with underground shelters, their level of dependence and importance to the ...

Consistent apparent adult survival and nest‐site fidelity of whimbrel Numenius phaeopus near Churchill, Manitoba, Canada over a 40 year period

Journal of Avian Biology, 2023
Reliable estimates of adult survival for many shorebird species are lacking. We used Cormack–Jolly–Seber (CJS) methods to provide an estimate of apparent, or local, survival (φ) of a population of whimbrels, Numenius phaeopus, breeding in the subarctic ...

Survival and movements of brown‐headed nuthatches after translocation to the Missouri Ozarks

Wildlife Society Bulletin, 2023
The brown‐headed nuthatch (Sitta pusilla) was likely extirpated from Missouri in the early 1900s as a result of habitat loss through extensive logging. Conservation partners including the Missouri Department of Conservation, United States Forest Service,

When is a parasite not a parasite? Effects of larval tick burdens on white-footed mouse survival [PDF]

, 2014
Many animal species can carry considerable burdens of ectoparasites: parasites living on the outside of a host's body. Ectoparasite infestation can decrease host survival, but the magnitude and even direction of survival effects can vary depending on the

Capture-mark-recapture modelling suggests an Endangered status for the Mayotte Island (eastern Africa) population of Indo-Pacific bottlenose dolphins

Endangered Species Research, 2014
We evaluated whether the Indo-Pacific bottlenose dolphins around the fast-developing island of Mayotte are threatened. We used opportunistic photo-identification data and capture-mark-recapture models to estimate key demographic parameters and then ...

Nest Success and Hatchling Survival of American Alligators Within Inland Wetlands of East Texas [PDF]

, 2012
Because of liberalization of American alligator (Alligator mississippiensis) harvest management in Texas, estimates of nest success and hatchling survival for inland populations are essential for long-term, sustainable population and harvest management ...
