Los perros podrían descender de dos poblaciones de lobos diferentes, según un estudio internacional

Un grupo internacional de genética y arqueología, liderado por el Instituto Francis Crick y en el que ha participado la Estación Biológica de Doñana – CSIC, ha podido rastrear el origen del perro hasta al menos dos poblaciones de lobos prehistóricos gracias al estudio de ADN de lobos de la Edad del Hielo. El trabajo permite avanzar un paso más en la investigación sobre dónde se domesticaron los perros, una de las mayores preguntas sin respuestas sobre la prehistoria humana.

Researchers show that a tropical montane mammal breaks ecological rules

A scientific team from the Doñana Biological Station – CSIC has looked at the variation in body size, appendage lengths, and other morphological traits across elevation and time in the Mountain Treeshrew, an endemic species from Borneo.
This new research suggests that this small mammal violates (entirely or partially) Bergmann’s and Allen’s rules. These are two key ecogeographical rules that describe size and shape variation among organisms, and predict that populations become...

Un nuevo estudio hace un recorrido por la biodiversidad del siglo XVI en España

A team from the Doñana Biological Station – CSIC has reviewed a exhaustive standardized historical survey (Relaciones Topográficas de Felipe II) with the goal of knowing which species inhabited the Iberian Peninsula at that time.

In the 16th century, bears and wolves coexisted with the Iberian lynx, wild asses still existed in Spain and eels were in every river. Data is collected in an open database for new research.

The aquatic fauna that arrived at a wish of a king

A study by Miguel Clavero, a researcher at the Doñana Biological Station – CSIC, reconstructs the history of the first introductions of pike, common carp, tench and Italian crayfish into Spain.

Interdisciplinary studies allow to introduce a long-term perspective on the magnitude and rhythm of changes in ecosystems, including biological invasions.

The Iberian hare population increases in Doñana after the decline of the European rabbit

Competition, predation, and diseases are key factors shaping animal communities. In recent decades, lagomorphs in Europe have been impacted by virus-borne diseases that have caused substantial declines in their populations and, subsequently, in many of their predators. We examined activity and habitat-use patterns of sympatric European rabbits (Oryctolagus cuniculus) and Iberian hares (Lepus granatensis) in Doñana National Park, during two periods of disease outbreak.
