Invasions of alien rodents have shown to have devastating effects on insular ecosystems. Here we review the ecological impacts of these species on the biodiversity of the Balearic and the Canary Islands. A total of seven species of introduced rodents (two rats, three mice, one dormouse, and one squirrel) have been recorded (six in the Balearics and four in(More)
In this study, a survey was conducted in order to determine the presence and pathogenic potential of free-living amoebae of Acanthamoeba genus in a population of Barbary Ground squirrels in Fuerteventura Island (Canary Islands, Spain) and Morocco. Identification of Acanthamoeba was based on the morphology of cyst and trophozoite forms and PCR amplification(More)
Although abiotic and biotic factors can interact to shape the spatial niche of a species, studies that explore the interactive effects of both at a local scale are rare. We demonstrate that one of the main axes (perch height) characterizing the spatial niche of a common lizard, Anolis sagrei, varies according to the interactive effects of weather and the(More)
This contribution aimed to predict the invasive Barbary ground squirrel (Atlantoxerus getulus) potentiality for invading the Canary Islands and western Mediterranean region, by determining firstly the climatic suitable areas in its native range and secondly, using presence data in the invaded range. Nineteen environmental variables submitted to a Principal(More)
A total of 51 and 21 adults of Barbary ground squirrels (Atlantoxerus getulus) were trapped during May–July 2006 from the introduced populations on Fuerteventura Island (Canary Islands) and the native populations in Morocco, respectively. One trematode, 1 cestode and 4 nematode species were recovered belonging to five families: Brachylaima sp.(More)
When competing for food or other resources, or when confronted with predators, young animals may be at a disadvantage relative to adults because of their smaller size. Additionally, the ongoing differentiation and growth of tissues may constrain performance during early ontogenetic stages. However, juveniles must feed before they can become reproductively(More)
The European rabbit (Oryctolagus cuniculus) is a conservation and social dilemma in the Canary Islands. It is the main prey of endangered species, it causes severe impacts on vegetation, as well as has a considerable hunting economic value but damages agriculture. We assessed drivers of European rabbit habitat selection on Fuerteventura Island (Canary(More)
Unfortunately, the fourth sentence in the abstract has been published incorrectly. This sentence is related to the last paragraph of the article main text, which fortunately is correct. Cats have not been introduced: ‘‘on at least 179,000 islands worldwide’’ (as is in the Abstract). As it is indicated in the last paragraph of the main article: ‘‘cats have(More)
Summit areas of oceanic islands constitute some of the most isolated ecosystems on earth, highly vulnerable to climate change and introduced species. Within the unique high-elevation communities of Tenerife (Canary Islands), reproductive success and thus long-term survival of species may depend on environmental suitability as well as threat by introduced(More)
Vertebrates often mediate seed dispersal systems, essential for the maintenance of biodiversity. Some of these acquire a complex multistep process in island environments, where for example a native predatory bird can predate upon a frugivorous vertebrate, dispersing seeds secondarily. These complex mutualistic processes are really threatened by biological(More)
