Space use, intra-territorial habitat preferences, and factors affecting both were studied in an invading population of American mink, Mustela vison, in two rivers of a Mediterranean region of Spain. Average linear home range was 1.19 ± 0.73 km (±SD) and core area was 0.21 ± 0.08 km for resident males (n = 10); while for females (n = 5) they were 0.54 ± 0.14(More)
Diet composition, niche measures, and prey consumption of three sympatric species of carnivores, one non-native and introduced, the American minkNeovison vison Schreber, 1777, and two native, the spotted genetGenetta genetta Linnaeus, 1758 and the Eurasian otterLutra lutra Linnaeus, 1758, were studied in a Spanish Mediterranean area. The study was based on(More)
Loss of biodiversity due to biological invasions is one of the most critical issues our society is facing. American mink is one of the most nefarious invasive non-native species and has major consequences for diversity, ecosystems and economics. A project to evaluate the impact of American mink has been carried out in Catalonia since 2000 under the aegis of(More)
The effectiveness of culling campaigns to eradicate or limit populations of the alien, invasive American mink in Catalonia was studied by comparing the annual relative abundance of culled versus non-culled populations. We selected three populations that were culled under government campaigns and a fourth that served as a control and hence was left(More)
We describe novel aspects of the social organisation of the Pyrenean desman, Galemys pyrenaicus, by studying home range and shelter use behaviour in a local population. A total of 45 individuals were trapped of which 20 provided informative radiotracking data. In contrast to the currently accepted hypothesis [Stone RD. The social organization of the(More)
The Pyrenean desman is considered a flagship species for biodiversity and evolution. However, its scientific knowledge is still under development and currently on debate, particularly in relation to its behavioural ecology and social organization. Based on the previous hypothesis of individual desmans being solitary and territorial, activity and space(More)
The Southern water vole, Arvicola sapidus, is endemic to the Iberian Peninsula and France. Despite being catalogued as vulnerable, our current knowledge of this species is not sufficient to establish measures for its conservation and recovery, particularly in riparian zones of Mediterranean mountain areas. The aim of this study was to identify factors(More)
Species with strict ecological requirements may provide new insights into the forces that shaped the geographic variation of genetic diversity. The Pyrenean desman, Galemys pyrenaicus, is a small semi-aquatic mammal that inhabits clean streams of the northern half of the Iberian Peninsula and is endangered in most of its geographic range, but its genetic(More)
Data on the morphology, relative growth and sexual dimorphism of the os coxae of a digging form of the northern water vole Arvicola terrestris (A.t. monticola) are given. Two hundred ninety-nine specimens (146 males and 153 females) caught in the Aran Valley (Spanish Pyrenees) were analyzed. The specimens were distributed into six classes of relative age,(More)
Maternal heart disease during pregnancy is the main cause of obstetric morbidity and mortality. We report the case of a 40-year-old woman with a history of myocardial infarction and percutaneous transluminal coronary angioplasty. The patient suffered a second heart attack and received pharmacologic treatment. After admission, she was seen to be 29 weeks(More)
