Effects of natural and artificial light on the nocturnal behaviour of the wall gecko

In the present study, the effects of nocturnal light level (i.e. lunar phase and artificial lighting) on the activity of wall geckos was evaluated (Tarentola mauritanica) of different ages in an anthropic environment. Data on individual behaviour were collected by direct observation and later examined by means of generalized linear mixed model (GLMM) analysis.

Stakeholders perceptions of the endangered Egyptian vulture: insights for conservation

The inclusion of perceptions, interests and needs of stakeholders in biodiversity conservation is critical for the long-term protection of endangered species. Yet, the social dimensions of endangered species conservation are often overlooked. Here, the social perceptions of the conservational importance of the globally endangered Egyptian vulture are examined in one of the most important breeding areas worldwide: the Bardenas Reales Protected Area, northern Spain.

Detection of Iberian terrestrial mammals employing olfactory, visual and auditory attractants

Whereas high lure specificity for mammal monitoring is often sought, little effort has been put into identifying general-purpose attractants for multispecies mammal surveys. We examined whether the olfactory lures ‘fatty acid scent’ and catnip oil differ in their ability to detect Iberian larger mammals; whether the addition of visual and acoustic stimuli increases detection efficiency; and whether environmental variables interact with lures to influence detection.

Endemic species underrepresented in the Habitats Directive

The Iberian Peninsula is a major European region of biodiversity, as it harbours more than 30% of European endemic species. Despite a number of studies having evaluated the ability of nature reserves to protect certain taxa, there is still a lack of knowledge on how Iberian endemic fauna are represented in these reserves. Here, biodiversity hotspots of Iberian endemicity were detected and the effectiveness of the Natura 2000 network in representing 249 endemic species from eight animal...

Intraspecific eye color variability in birds and mammals: a recent evolutionary event exclusive to humans and domestic animals

Human populations and breeds of domestic animals are composed of individuals with a multiplicity of eye (= iris) colorations. Some wild birds and mammals may have intraspecific eye color variability, but this variation seems to be due to the developmental stage of the individual, its breeding status, and/or sexual dimorphism. In other words, eye colour tends to be a species-specific trait in wild animals, and the exceptions are species in which individuals of the same age group or gender all...
