| Summary: | [eng] Bats are considered an excellent group of environmental health indicator. Besides its ecological importance, the bats have acquired in recent years a great interest in epidemiological studies because they are an important reservoir of emerging viral zoonoses. This paper highlights the ecological and epidemiological information obtained since 1993 in the Balearic Islands. During these years we have used different methodologies: exploration of underground cavities, installing Japanese nets and recording and analysis of ultrasonic signals emitted by bats. The results obtained indicate that the Balearic Islands have a very high diversity of bats, with the presence of 19-20 species, the most abundant Pipistrellus pipistrellus, Pipistrellus kuhlii, Pipistrellus pygmaeus and Tadarida teniotis. These four species together with Hypsugo Savii, Plecotus austriacus, Rhinolophus ferrumequinum and Rhinolophus hipposideros, are present in all the major islands of the archipelago. The loss and alteration of the shelters have a negative impact on bat populations. However, is confirmed the gradual recovery of the colony of Miniopterus schreibersii hibernation in Minorca, after the great mortality that occurred in 2003. We have also verified several movements between different cavities either between islands or between one island refuges. We observed spread of lyssavirus in Mallorca and Menorca colonies of bats, although that the risk of transmission of a bat to the human species is very low. [cat] Les ratapinyades són considerades un excel·lent grup indicador de la salut ambiental. A més a més de la importància ecològica, els quiròpters han adquirit els darrers anys un gran interès en estudis epidemiològics perquè són un important reservori de zoonosis víriques emergents. El present treball dóna a conèixer la informació ecològica i epidemiològica obtinguda des de l’any 1993 a les Illes Balears. Durant aquests anys hem utilitzat diferents metodologies: prospeccions de cavitats subterrànies, instal·lació de xarxes japoneses ... |
