Invasive in many European countries, the American mink (Neovison vison) was introduced in Portugal in the late 1980’s, presumably escaping from Spanish fur farms close to the border. In spite of the biological richness of the invaded area, no study ever addressed the evolution of the invasion process. We aimed to investigate the current distribution and(More)
Road barrier effect is among the foremost negative impacts of roads on wildlife. Knowledge of the factors responsible for the road barrier effect is crucial to understand and predict species' responses to roads, and to improve mitigation measures in the context of management and conservation. We built a set of hypothesis aiming to infer the most probable(More)
The stone marten is a widely distributed mustelid in the Palaearctic region that exhibits variable habitat preferences in different parts of its range. The species is a Holocene immigrant from southwest Asia which, according to fossil remains, followed the expansion of the Neolithic farming cultures into Europe and possibly colonized the Iberian Peninsula(More)
The Natura 2000 network is the centerpiece of European nature conservation policy but its effectiveness is challenged by ongoing landscape change. Our objective was to assess landscape connectivity between Natura 2000 sites in the biodiversity-rich western Mediterranean region. We used the wood mouse as a focal species with short-range dispersal and(More)
We report a panel of 12 microsatellite markers, including nine novel polymorphic loci isolated in the European polecat and three loci previously developed in closely related species, for genetic studies of polecats and ferrets. We tested the panel at fine geographic scales in polecat and domestic ferret populations of Britain and Portugal and at a broad(More)
This study reports the first set of microsatellite markers for the weasel (Mustela nivalis). We chose to isolate loci with tetranucleotide repeat motifs because they can be scored less ambiguously than the more commonly used dinucleotide loci. All 11 loci showed considerable variation within a population sample of 28 individuals from Portugal, with number(More)
The Egyptian weasel (Mustela subpalmata) is a small mustelid with a distribution restricted to the lower Nile Valley and the Nile Delta. Traditionally considered a subspecies of the least weasel (M. nivalis), it is currently recognized as a separate species based on morphology. Here we present the first genetic assessment of the taxonomic status of the(More)
Introduced mammalian predators have negatively affected native biota and ecological processes in ecosystems across the globe. The least weasel (Mustela nivalis) is a Holarctic mustelid carnivore that has been considered one of the world’s worst invasive alien species. It has been introduced to several islands in the Mediterranean Sea and Atlantic Ocean, and(More)
The identification of populations and spatial genetic patterns is important for ecological and conservation research, and spatially explicit individual-based methods have been recognised as powerful tools in this context. Mammalian carnivores are intrinsically vulnerable to habitat fragmentation but not much is known about the genetic consequences of(More)
The original version of the article unfortunately contained an error in Fig. 1. A typo in a geographic coordinate caused a Sicilian sample to be incorrectly mapped in southern Italy (white pentagon on the coast of the Gulf of Taranto). The corrected Fig. 1 can be found here. The caption of the figure remains unchanged.
