Studied was geographic variation in 12 skull measurements of 24 samples of Rhinolophus ferrumequinum (Schreber, 1774) from south-eastern Europe. Morphological principal component 1 (69.5% of variance explained) was highly size related. Morphological principal component 2 (10.6% of variance explained) correlated significantly only with interorbital constriction. Most of the interlocality variation was due to size, which increased clinally from the north-west to the south-east. Clustering of character means produced two clusters. The ranges of overlap of condylocanine length between the two siite-related clusters showed no evidence of the existence of two clearly defined populations. July precipitation levels best explained the size variation observed. T propose that if. f. martinoi he considered a synonym of R. f, ferrumequinum.

The first European case of bat rabies was reported in 1954. Since then, more than 800 cases have been confirmed from 13 countries. The causative agents are European Bat Lyssavirus Type-1 (EBLV-1) and Type-2 (EBLV-2). The natural host of EBLV-1 seems to be the serotine bat (Eptesicus serotinus) with more than 95% of all cases reported in this species. Although much fewer EBLV-2 cases have been identified, it seems that Myotis dasycneme and M. daubentonii are likely to be the principal hosts' species for this virus. The ecological mechanisms underlying the transmission of EBLV-1 and EBLV-2 are still poorly understood. In order to assess the public health risks associated with EBLVs and the implications for bat conservation, some issues need urgent clarification. In this review some of the most pressing topics will be addressed. Only collaboration between a range of disciplines that include virologists, epidemiologists and bat conservationists will be able to elucidate some of these unanswered questions.

The roost area selection of reproductive female western barbastelles was examined throughout four study seasons (2004–2007) via radio-tracking and automated acoustic monitoring. We specifically analysed the spatial structure of the roosting habitat and roost fidelity including a flight path connecting the roosts. We radio-tracked 13 colony members to 46 natural roosts, mainly dead oaks with large pieces of loose bark. Simultaneous tracking of four pairs of females revealed the existence of subgroups and fission-fusion-behaviour in Barbastella barbastellus. The colony displayed fidelity to the roost area rather than to single roost trees, although some trees were reused in two or three study seasons. Bimodal activity patterns obtained from acoustic monitoring indicated that the flight path connecting two core roosting areas functioned as a commuting corridor.
