Estructura genética del “roble belloto” Quercus skinneri (Fagaceae) en El Salvador

Cuadernos de investigación UNED
Introducción: En El Salvador, Quercus skinneri Benth. está restringido a zonas templadas de altitud. La falta de estudios genéticos limita la toma de decisiones para su conservación, a pesar de la importancia de la diversidad genética en estos bosques ...

Translocation effects on regional and local population viability and connectivity

Conservation Biology, Volume 40, Issue 4, August 2026.
Abstract Translocations and reintroductions aim to improve the viability of isolated populations and promote connectivity for large carnivores. However, there is no established framework for assessing their success. We used the Eurasian lynx (Lynx lynx) in western and central Europe to assess the impact of translocations on the viability of six ...

Unexpected spatial aggregation between two species of hummingbirds and their inconsistent spatial interactions with native and exotic plants in an urban ecological reserve

Ibis, Volume 167, Issue 4, Page 927-944, October 2025.
Hummingbirds play an important role as pollinators and are one of the primary examples of animal–plant coevolution. However, factors such as land‐use change, urbanization, exotic species introductions and the disappearance of native plants can negatively affect the persistence of hummingbird populations.

Estructura molecular y poblacional del ganado criollo Colombiano (GCC)

Revista Colombiana de Ciencias Pecuarias, 2016
Resumen El ganado criollo colombiano comprende un grupo de razas que se han adaptado por más de 400 años a las condiciones ecoclimáticas de nuestro país, razón por la cual poseen características adaptativas de suma importancia que podrían ser utilizadas de una manera racional en programas de conservación y mejoramiento animal.

Demographic performance review of a reintroduction project: Iberian lynx in Extremadura

Journal of Applied Ecology, Volume 62, Issue 9, Page 2189-2201, September 2025.
Demographic performance reviews are essential for understanding the drivers of population growth and for evaluating the outcomes of reintroduction initiatives. IPMs as exemplified by our Iberian lynx case study provide a powerful and flexible framework for quantifying reintroduction performance and addressing key research and management questions.

Mediterranean octocoral populations exposed to marine heatwaves are less resilient to disturbances

Journal of Animal Ecology, Volume 94, Issue 8, Page 1528-1541, August 2025.
We demonstrate that marine heat waves decrease the resilience of Mediterranean octocorals to further disturbances. Abstract The effects of climate change are now more pervasive than ever. Marine ecosystems have been particularly impacted by climate change, with marine heatwaves (MHWs) being a strong driver of mass mortality events.

Mutational load and adaptive variation are shaped by climate and species range dynamics in Vitis arizonica

New Phytologist, Volume 247, Issue 2, Page 998-1014, July 2025.
Summary Genetic load can reduce fitness and hinder adaptation. While its genetic underpinnings are well established, the influence of environmental variation on genetic load is less well characterized, as is the relationship between genetic load and putatively adaptive genetic variation.

Delineating ecologically distinct groups for annual cycle management of a declining shorebird

Journal of Applied Ecology, Volume 62, Issue 5, Page 1152-1165, May 2025.
Using measurements of migratory connectivity in concert with expert opinion can define ecologically distinct groups for wildlife management that differ in the environmental conditions they experience across seasons of the annual cycle, which is a key component for understanding and reversing declines of migratory species. Abstract Patterns of migratory

Aspectos poblacionales y desplazamiento de mariposas Hamadryas (Nymphalidae) en distintos usos de suelo en los Montes de María, Colombia

Revista Mexicana de Biodiversidad, 2023
Los estudios poblacionales de mariposas en el Caribe colombiano son escasos, razón por la cual se analizó la estructura poblacional y el desplazamiento de Hamadryas Hübner (1806) en diferentes usos del suelo en un paisaje fragmentado en los Montes de ...
