Genetic and environmental factors associated with survival of a rare songbird in a fragmented urban landscape

Conservation Science and Practice
The coastal Cactus Wren (Campylorhynchus brunneicapillus) persists in small and fragmented populations throughout southern California that are subject to genetic drift and inbreeding.

Moderate evidence for the sex‐dependent effect of poisoning on adult survival in a long‐lived raptor species [PDF]

Ecology and Evolution
Survival rate is usually the greatest contributor to population growth in long‐lived species, and its accurate estimation along with the evaluation of the factors influencing it is therefore essential for effective conservation.

Apparent Survival of Territorial Golden Eagles Using Non-Invasive Genetic Profiling. [PDF]

Ecol Evol
In a novel study for the species, DNA was extracted from moulted feathers over 4 years involving 21% of the Scottish population of territorial golden eagles, and individuals' genetic profiles were analysed for apparent survival rates. Results showed sexual differences but not between two sub‐populations; very few cases of breeding dispersal were ...

Contrasting Patterns of Inbreeding and Inbreeding Depression in Co-Occurring Spotted Turtle and Eastern Box Turtle Populations. [PDF]

Ecol Evol
We found that while spotted turtles had smaller population sizes, occupied smaller habitat patches, had smaller home ranges, and had higher baseline physiological stress levels than box turtles, the box turtle populations had much higher inbreeding coefficients than the spotted turtle populations.

Weather Extremes in the Mediterranean Winter Are Associated With Reduced Apparent Survival and Delayed Initiation of Egg-Laying in a Migratory Raptor. [PDF]

Ecol Evol
We analysed capture‐recapture data of breeding Eurasian kestrels (Falco tinnunculus) in western Finland during 1985–2018 to study how environmental conditions in their boreal breeding areas and Mediterranean wintering areas affect adult survival rate and timing of laying.

Estimating abundance of Eastern Canada-West Greenland bowhead whales using genetic mark-recapture analyses

Global Ecology and Conservation, 2023
The Eastern Canada-West Greenland (EC-WG) bowhead whale (Balaena mysticetus) population is widely distributed across the eastern Canadian Arctic and across Baffin Bay to the western coast of Greenland.

Continuous time-dependent individual covariates and the Cormack-Jolly-Seber model

Animal Biodiversity and Conservation, 2007
Covariantes continuas individuales dependientes del tiempo y el modelo de Cormack-Jolly-Seber El modelo de Cormack–Jolly–Seber proporciona el marco básico para analizar la supervivencia de animales en poblaciones abiertas utilizando datos de captura ...

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.

Providing evidence for the conservation of a rare forest butterfly: Results from a three-year capture-mark-recapture study

Basic and Applied Ecology, 2023
Species living in spatially structured populations require a network of interconnected habitat patches. Due to changes in forest management, this network of habitat patches has been lost for insect species inhabiting open spots within forests. We studied

Climate Change and the Spatiotemporal Variation in Survival of a Long-Distance Migrant (White Stork, Ciconia ciconia) across Western Europe

Birds, 2021
The spatial variation in the strength of climate change may lead to different impacts on migratory birds using different breeding areas across a region.
