Long-Term Changes in Survival of Eurasian Lynx in Three Reintroduced Populations in Switzerland. [PDF]

Ecol Evol
In this study, we analyzed the long‐term development of survival rates for different sexes and age classes in three reintroduced Swiss lynx populations. A novel modeling approach allowed us to combine picture data, telemetry data, and dead recoveries over a monitoring period of 25 years (1997–2022).

The 4th Dimension in Animal Movement: The Effect of Temporal Resolution and Landscape Configuration in Habitat-Selection Analyses. [PDF]

Ecol Evol
Advances in tracking technology enable finer temporal resolution in animal movement data, but the impact of sampling intervals on habitat‐selection analysis remains unclear. Using simulations and wild boar data from Germany, researchers found that higher sampling intervals are needed in highly autocorrelated landscapes to capture habitat variability ...

Recent Divergence and Microgeographic Genetic Structure in an Endangered Australian Songbird: The Southern Black-Throated Finch. [PDF]

Ecol Evol
The endangered southern black‐throated finch Poephila cincta cincta has experienced an ~80% range contraction over the last century, and ongoing habitat loss increases the risk of its extinction. Using reduced representation and whole genome sequencing, we examine the divergence history of northern and southern black‐throated finches and find evidence ...

A Dominant Founder Lineage Has Possible Fitness Costs for the Endangered Mexican Grey Wolf. [PDF]

Mol Ecol
ABSTRACT The Mexican grey wolf (Canis lupus baileyi) is an endangered and genetically distinct subspecies of grey wolf adapted to the warm climates of the southwestern United States and Mexico. Following centuries of eradication efforts, Mexican grey wolves were protected under the Endangered Species Act in 1976, prompting an international ex situ ...

Tracking the Ghosts of the Himalayas: Snow Leopard Conservation Insights From Satellite Collar Data. [PDF]

Ecol Evol
We analysed spatiotemporal dynamics using satellite telemetry data to understand differences in movement patterns, activity budgeting and home range utilisation between male and female snow leopards, satellite‐collared in the northeastern Himalayas of Nepal.

Multidisciplinary monitoring and stakeholder engagement support large carnivore restoration in human-dominated landscape. [PDF]

Ecol Appl
Abstract Translocations are central to large carnivore restoration efforts, but inadequate monitoring often inhibits effective conservation decision‐making. Extinctions, reintroductions, illegal killings, and high inbreeding levels of the Central European populations of Eurasian lynx (Lynx lynx) typify the carnivore conservation challenges in the ...

Genomic Insights Into Red Squirrels in Scotland Reveal Loss of Heterozygosity Associated With Extreme Founder Effects. [PDF]

Evol Appl
ABSTRACT Remnant populations of endangered species often have complex demographic histories associated with human impact. This can present challenges for conservation as populations modified by human activity may require bespoke management. The Eurasian red squirrel, Sciurus vulgaris (L., 1758), is endangered in the UK.

Habitat Requirements of the Florida Panther

EDIS, 2015
The Florida panther (Puma concolor coryi) was listed as endangered under the Endangered Species Act in 1967. Habitat loss and fragmentation are primary threats, driven by urban development and the conversion of rangelands to row crops, citrus production,

Survival and Mortality of Pumas (Puma concolor) in a Fragmented, Urbanizing Landscape. [PDF]

PLoS ONE, 2015
Wide-ranging large carnivores pose myriad challenges for conservation, especially in highly fragmented landscapes. Over a 13-year period, we combined monitoring of radio collared pumas (Puma concolor) with complementary multi-generational genetic ...

Osteological corroboration of pathological stress in a population of endangered Florida pumas (Puma concolor coryi) [PDF]

Animal Conservation, 1998
AbstractThe Florida panther, Puma concolor coryi, is a subspecies on the verge of extinction. Recent field studies have shown the dwindling population to be suffering from numerous physical problems manifest in their soft tissues. Here we explore the skulls and skeletons of more than 50 P.
