Stone martens (Martes foina) occur in urban environments in many parts of continental Europe, where they cause a nuisance by denning in inhabited houses. We radio tracked 13 stone martens (10 females, 3 males) in two towns in southern Luxembourg during a 2-year period, in order to investigate den preferences and patterns of den use. We predicted that urban martens would make more use of buildings and less use of natural den sites than do their rural counterparts. All martens used multiple den sites but use was concentrated on a subset of these, between which individuals shifted frequently. Denning was almost exclusively in buildings (97.1%), with use of inhabited buildings being the highest (41.9%) recorded to date for this species. Inhabited buildings were used more extensively in winter, presumably because they were warmer and better insulated. We conclude that stone martens can successfully adapt their denning behaviour to an urban environment and that they use anthropogenic den sites more often than do most other mesocarnivore urban adapters.

Aim Thermophilic species persisted in southern refugia during the cold phases of the Pleistocene, and expanded northwards during warming. These processes caused genetic imprints, such as a differentiation of genetic lineages and a loss of genetic diversity in the wake of (re)colonization. We used molecular markers and species distribution models (SDMs) to study the impact of range dynamics on the common wall lizard, Podarcis muralis, from southern refugia to the northern range margin. Location Parts of the Western Palaearctic. Methods We genotyped 10 polymorphic microsatellites in 282 individuals of P. muralis and sequenced the mitochondrial DNA (mtDNA) cytochrome b gene to study the genetic structure, divergence times and ancestral distributions. Furthermore, we generated SDMs for climate scenarios for 6 and 21 ka derived from two different global circulation models. Results We detected two major mtDNA lineages – a western France clade (Pyrenees to Brittany), and an eastern France clade (southern France to Germany, Belgium and Luxembourg). This split was dated to c. 1.23 Ma. The latter clade was divided into two subclades, which diverged c. 0.38 Ma. Genetic diversity of microsatellites within each clade was nested and showed a significant loss of genetic diversity from south to north, a strong pattern of allele surfing across nearly all loci, and an increase in genetic differentiation towards the northern range margin. Results from SDMs suggest that southward range retraction during the late glacial period split the distribution into geographically distinct refugia. Main conclusions The strong genetic differentiation mirrors the effects of long‐term isolation of P. muralis in multiple refugia. Post‐glacial recolonization of Northern Europe has taken place from two distinct refugia, most probably along river systems (Rhône, Rhine, Moselle) and along the Atlantic coastline, with subsequent nested elimination of genetic diversity and increasing genetic differentiation at the northern range margin.

Rabid bats are regularly reported in Europe, especially in countries that have implemented a bat surveillance network. In May 2013, bat rabies was evidenced for the first time in Luxembourg (southern city of Differdange). The rabies virus, an EBLV-1b strain, was diagnosed in a serotine bat that bit a 29-year-old male person while he was asleep. The man received rapidly a post-exposure RABV treatment and was put under strict medical supervision.
