Article
Drylands range across more than half of the global terrestrial area and harbour about a quarter of continental vertebrate species, many of them endemic. However, this fauna is being increasingly threatened, in particular the one that inhabits deserts, one of the last biomes on earth. This work tracks the most relevant global change drivers acting o...

Background Ethnozoological knowledge is less documented than ethnobotanical. With this field study, we aim to record and analyze the Riffian Berber knowledge about the use of animals in traditional human and veterinary medicine. Our research question is what is their knowledge of ethnozoological practices? Methods We performed semi-structured inte...
Article
The Iberian ibex (Capra pyrenaica) is an endemic species of the Iberian Peninsula that is expanding throughout the province of Granada (Andalucía). Historical records of this species in the Sierra Elvira massif, in the Vega de Granada, are missing. This recent permanent establishment of this species in the study area allows us to examine different...

Article
The key to fighting a biological invasion may lie in understanding every variable that can explain its success. The Enemy Release Hypothesis (ERH) states that when an invader arrives to a new environment, the absence of its common enemies (predators, parasites and competitors) facilitates the invasion success. The Horseshoe whip snake ( Hemorrhois...
Article
Trace elements can be toxic when they cannot be easily removed after entering an ecosystem, so a long-term assessment is fundamental to guide ecosystem restoration after catastrophic pollution. In 1998, a pyrite mining accident in Aznalcóllar (south-western Spain) spilled toxic waste over a large area of the Guadiamar river basin, where, after rest...
Article
Fire is one of the main disturbances to terrestrial environments, transforming habitat structure and affecting community composition. Coupled with fire, forest type and vegetation structure modulate the taxonomic response to fire by ectotherm organisms such as reptiles. The response of each reptile species to fire is based on their functional attri...

The designation of taxonomic units has important implications for the understanding and conservation of biodiversity. Eurasian vipers are a monophyletic group of viperid snakes (Serpentes, Viperinae), currently comprising four genera (Daboia, Macrovipera, Montivipera and Vipera) and up to 40 species. Taxonomic units have been described using a wide...
Article
The greatest threat to biodiversity is the alteration and destruction of habitats, and one of the causes is tree plantation, which normally are monospecific and unnatural high-density forest stands. In Spain these contain mainly Pinus species, and cover 25% of the forested area. Due to their dense canopy cover, these monocultures harbor poor commun...
