Identifying the demographic pathways linking environmental covariates to population dynamics in an avian migrant. [PDF]

Ecol Appl
Abstract Understanding and predicting the effects of climate change on populations requires linking the environmental conditions to demographic rates and the demographic rates to population‐level consequences, but often this complete demographic pathway is not studied.

Extreme polygyny results in intersex differences in age-dependent survival of a highly dimorphic marine mammal

Royal Society Open Science, 2023
Developmental differences in vital rates are especially profound in polygamous mating systems. Southern elephant seals (Mirounga leonina) are highly dimorphic and extremely polygynous marine mammals.

Non-parallel changes in songbird migration timing are not explained by changes in stopover duration [PDF]

PeerJ, 2020
Shifts in the timing of animal migration are widespread and well-documented; however, the mechanism underlying these changes is largely unknown. In this study, we test the hypothesis that systematic changes in stopover duration—the time that individuals ...

Cryptic disease-induced mortality may cause host extinction in an apparently stable host- parasite system [PDF]

, 2017
The decline of wildlife populations due to emerging infectious disease often shows a common pattern: the parasite invades a naive host population, producing epidemic disease and a population decline, sometimes with extirpation.

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

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 ...

An empirical Bayesian approach to incorporate directional movement information from a forage fish into the Arnason-Schwarz mark-recapture model

Movement Ecology, 2021
Background Over the past two decades, various species of forage fish have been successfully implanted with miniaturized acoustic transmitters and subsequently monitored using stationary acoustic receivers.
