Humanised landscapes are causing population declines and even extinctions of wildlife, whereas a limited number of species are adapting to the new niches and resources within these modified habitats. Synanthropy is widespread among many vertebrates and often causes co-habitation conflicts between humans and wildlife species. Bats often roost in anthropogenic structures, and especially in the tropics, mitigation of human-bat conflicts arising from co-habitation is hampered by a paucity of research focusing on roost preferences. We assessed roost selection by bats in villages around Ranomafana National Park, eastern Madagascar. Ten villages were surveyed, with bats occupying 21 of the 180 evaluated buildings. Of those, 17 were public buildings harbouring large molossid colonies. Although beneficial ecosystem services provided by bats are well-known, several cases of colony eviction were noted, mostly due to unwanted co-habitation. Bat preference was driven by the type of building, its height and a lack of fire use by the inhabitants. Colonies were mainly found under metal sheets within large empty chambers, whereas only isolated bats were detected in the roofs of traditional cabins. Temperatures up to 50◦C were recorded inside a roost, representing one of the highest temperatures recorded for an African maternity roost. Molossidae bats appear to have found a suitable alternative to their native roosts in hollow, old and tall trees in pristine forests, which are becoming rare in Madagascar. This suggests that human-bat interactions in Madagascar will likely increase alongside rural development and the loss of primary forest habitats. Shifting to modern construction methods while combining traditional techniques with proper roof sealing could prevent the establishment of bat colonies in undesired locations, whereas co-habitation conflicts could alternatively be minimised by reducing direct interaction with humans. In light of our results, we urge caution with bat evictions, and greater attention when introducing modern building practices, often supported by foreign initiatives, to poor rural communities in developing countries. © 2017, Associazione Teriologica Italiana onlus.

The Algerian hedgehog, Atelerix algirus, is recorded from North Africa, the Balearic, Canary and Maltese islands, and into parts of the Mediterranean coastal regions of Spain. The lack of an archeozoological record in Europe, Balearic, Maltese or Canary Islands has led several authors to postulate recent introductions by humans, but few studies actually investigated this hypothesis. We used both mitochondrial and nuclear genes to test it. To this aim, we widely sampled the Algerian hedgehog in North Africa (Algeria, Morocco and Tunisia), continental Spain (Catalonia), and Balearic and Canary islands. Our mitochondrial and nuclear data are consistent and show low genetic diversity across the geographical range of the Algerian hedgehog. Our results suggest the recent colonisation of Spain, Balearic and Canary Islands by this species (Holocene), probably mediated by humans. Several subspecies, mainly based on pelage variations, have been described either from mainland or island populations, but our data do not show any genetic discontinuity, suggesting that subspecific recognition may be unwarranted. © 2016 by De Gruyter.

A total of 109 badger Meles meles skulls from Catalonia (north-eastern Iberian Peninsula) were studied for helminths. The tremadode Troglotrema acutum is reported here for the first time in the Eurasian badger in the Iberian Peninsula and southern Europe. Three methodologies were used to detect this trematode: an examination for surface lesions, axial computed tomography and fresh skull dissection. The damage caused in the affected skulls is described, along with details regarding the use of computed tomography to detect hyperostosis, leakage in the sinus structure and bone surface erosion in the affected skulls. © 2011 Cambridge University Press.

Urban Ecosystems | Year: 2016

Impact mitigation practices are currently one of the hottest topics in conservation and regarded as priorities worldwide. Forest bat populations are known to provide important ecosystem services such as pest control and bat boxes have become one of the most popular management options for counteracting the loss of roosts. However, bat boxes tend to be employed in non-native forests near highly humanized areas where human disturbance is higher. The aim of this study was to evaluate how the surrounding landscape composition affects bat box occupancy in urban non-native forests along the Mediterranean corridor in the Northeastern Iberian Peninsula. Two hundred wooden bat boxes were monitored in young non-native forests in the period 2004–2012. The influence of land cover on occupancy rate of bat boxes was analysed at the landscape level in a 5 km buffer around bat-box stations. In total, 1659 inspections were carried out, in which a 15 % occupancy rate was detected. Bat boxes hosted three different species (Pipistrellus pygmaeus, Pipistrellus kuhlii and Nyctalus leisleri). More than 70 % of the occupancy can be explained by habitat and spatial composition. The presence of urban areas around bat boxes tends to have a negative impact on bat occupation rates; by contrast, forest coverage has a positive effect, especially for the tree-dwelling bats. These patterns could be associated with the large number of available roosts in buildings, microhabitat or phylopatry. Thus, to increase success, we suggest that landscape composition should be considered when using bat boxes for conservation. © 2016 Springer Science+Business Media New York

Pest control through integrated pest management systems stands as a very convenient sustainable hazard-free alternative to pesticides, which are a growing global concern if overused. The ability of the soprano pipistrelle bat (Pipistrellus pygmaeus) to control the rice borer moth (Chilo supressalis), which constitutes a major pest of rice around the world, was studied in the Ebre Delta, Northeastern Iberia. Evidence was found on the ability of this particular bat species to control borer infestations: (a) the moth was consumed during at least the last two peaks of the moth activity, when most crop damage is done; (b) the activity of bats significantly increased with moth abundance in the rice paddies; (c) the pest levels have declined in the study area (Buda Island, Eastern Ebre Delta) after the deployment of bat boxes and their subsequent occupation by soprano pipistrelles. The value of the ecosystem service provided by bats was estimated at a minimum of 21€ per hectare, equivalent to the avoided pesticide expenditure alone. We suggest that this natural service can be enhanced by providing bat populations with artificial roosts in rice paddies were some key ecosystem features are present. © 2015 Deutsche Gesellschaft für Säugetierkunde.
