Estima de una población de corzo mediante modelos de captura-recaptura clásicos y espacialmente explícitos

Galemys, Spanish Journal of Mammalogy, 2013
[ES]: La conservación y gestión de la fauna requiere de sistemas precisos de seguimiento y estima de sus poblaciones. En este contexto se ha estimado el tamaño de la población de corzo (Capreolus capreolus) en Quintos de Mora (Toledo, España). La estima se ha realizado en dos áreas de la misma finca; una zona abierta, y en una zona cerrada colindante ...

Ecology of reintroduced Rocky Mountain bighorn sheep in Dinosaur National Monument La Ecología de Borrego Cimarron de las Montañas Rocosas Reintroducido en el Monumento Nacional de Dinosaurio

Wildlife Monographs, Volume 223, Issue 1, August 2026.
We synthesized GPS telemetry, genetic, and pathogen data to evaluate metapopulation processes in a reintroduced Rocky Mountain bighorn sheep (Ovis canadensis canadensis) population in Dinosaur National Monument. We estimated subpopulation‐specific abundances and found 4 small subpopulations with high genetic diversity, partial connectivity, and ...

Effects of selective harvest on antler size of white‐tailed deer in Texas, USA

Wildlife Monographs, Volume 222, Issue 1, June 2026.
We conducted 20 years of experiments on the selective harvest of white‐tailed deer by antler size, judged inferior, in 2 areas of South Texas, USA. Selective harvest increased the phenotypic antler size of older males in one study area but not the other. There was little evidence of evolution resulting from selective harvesting. Abstract There has been

A spatially explicit approach for estimating space use and density of common genets

Animal Biodiversity and Conservation, 2014
Un método espacialmente explícito para estimar el uso del espacio y la densidad de la jineta común Muchas especies que se presentan en bajas densidades no se estiman con precisión utilizando métodos de captura y recaptura, puesto que tales técnicas ...

Abundance and Seasonal Dynamics of Guiana Dolphins (Sotalia guianensis) in Southern Brazilian Estuarine and Adjacent Coastal Waters

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 36, Issue 2, February 2026.
ABSTRACT Estimating population parameters is crucial for understanding species dynamics and assessing anthropogenic impacts, thereby supporting conservation efforts. We evaluate key population parameters—group structure, abundance and capture–recapture probabilities—of the Guiana dolphin in the Paranaguá Estuarine Complex and adjacent coastal waters ...

Sustained contraceptive‐level plasma concentrations of 4,4′‐dinitrocarbanilide in free‐ranging urban feral pigeons fed a custom bait Niveles plasmáticos altos y sostenidos de 4,4′‐dinitrocarbanilida en palomas domésticas libres alimentadas con un cebo anticonceptivo

Wildlife Society Bulletin, Volume 49, Issue 4, December 2025.
We assessed the acceptability and consumption of a custom‐developed nicarbazin bait for feral pigeons, inferred its contraceptive efficacy, and evaluated the reversibility of its effects upon cessation of treatment. Only feral pigeons consumed the bait, except for one eared dove that also ingested the food. Continuous administration of this bait raised

Precipitation and Temperature‐Dependent Locomotor Performance Drive the Abundance of a Neotropical Lizard

Biotropica, Volume 57, Issue 6, November 2025.
We investigated how climate and ecophysiology affect the demography of the lizard Tropidurus oreadicus in the Brazilian Cerrado. While lizards were more frequently captured in the dry season, their abundance peaked during the rainy season when their locomotor performance was highest.
