The gray wolf (Canis lupus) population on the Iberian Peninsula was the largest in western and central Europe during most of the 20th century, with its size apparently never under a few hundred individuals. After partial legal protection in the 1970s in Spain, the northwest Iberian population increased to about 300-350 packs and then stabilized. In...

The Argentine ant is one of the five worst invasive ants. Recently it has been shown that one of the main compounds of its pygidial gland, iridomyrmecin, is used as a venom against competitors and enemies. Here, we explore the variability in the quantities of iridomyrmecin of individual workers, along a range of locations pertaining to both its nat...

Gray wolves (Canis lupus) in the Iberian Peninsula declined substantially in both range and population size in the last few centuries due to human persecution and habitat fragmentation. However, unlike many other western European populations, gray wolves never went extinct in Iberia. Since the minimum number was recorded around 1970, their numbers...

Ecological and conservation genetic studies often use noninvasive sampling, especially with elusive or endangered species. Because microsatellites are generally short in length, they can be amplified from low quality samples such as feces. Microsatellites are highly polymorphic so few markers are enough for reliable individual identification, kinsh...

One of the main traits of invasive ants is the formation of supercolonies, large networks of polygynous nests lacking intraspecific competition, which allows them to reach high densities that facilitate their spread. However, different supercolonies exhibit different success in expanding along the world. Here, we explore whether the main chemical d...

The endangered Mexican wolf (Canis lupus baileyi) is known to carry exceedingly low levels of genetic diversity. This could be i) the result of long‐term evolutionary patterns as they exist at the southernmost limit of the species distribution at a relatively reduced effective size, or ii) due to rapid population decline caused by human persecution...

Hacia análisis genéticos de alto rendimiento de muestras fecales de fauna silvestre La secuenciación de alto rendimiento ofrece nuevas posibilidades en ecología molecular y biología de la conservación. Sin embargo, el potencial de esta técnica no ha sido totalmente explotado para estudios no invasivos, a partir de muestras fecales, de fauna en libe...

Sierra Nevada representa uno de los puntos con mayor biodiversidad de la península ibérica. Dentro de este área existe una gran amenaza para las poblaciones de vertebrados terrestres, un canal de conducción de agua con una longitud de 6890 metros conocido como Canal de la Espartera. Está situado dentro de porciones de parque natural y parque nacion...

El objetivo de este trabajo es conocer la variación en la forma alar de Parnassius apollo nevadensis, lepidóptero endémico de Sierra Nevada, en función del sexo y la altitud. Para ello, utilizamos herramientas de Morfometría Geométrica aplicadas a fotografías de individuos de ambos sexos de poblaciones situadas a lo largo de su área de distribución...

El Parque Natural de Sierra Nevada representa uno de los puntos con mayor biodiversidad de la Península Ibérica y como tal debe ser protegido. No obstante, dentro de este área existe una gran amenaza para las poblaciones de vertebrados terrestres: se trata de un canal de conducción de agua situado en la zona de Cumbres Verdes conocido como Canal d...
