“…Rhinolophus mehelyi foraged in a range of different wooded habitats, including those characterized by a loose tree cover such as the dehesa and olive groves/almond orchards, while R. euryale selected broadleaved woodland, as observed elsewhere (Russo et al, 2002;Aihartza et al, 2003;Goiti et al, 2003), but not other wooded habitats, such as the dehesa, olive groves and almond orchards. Neither species used open habitats.…”

Habitat selection was studied in two rhinolophid (Chiroptera) species, Rhinolophus mehelyi and R. euryale, breeding in the same roost in south-west Spain. The first analysis of habitat selection by R. mehelyi is provided, and the hypothesis explored that despite their close relatedness, in sympatry the two bat species showed different habitat preferences. For both species, the least preferred habitats were open habitats such as scrubland, grassland and arable land. As found elsewhere, R. euryale preferred broadleaved woodland. In addition, R. mehelyi also foraged in habitats characterized by loose trees, such as the 'dehesa', a semi-natural oak savanna. The progressive disappearance of the dehesa, jeopardized by land-use change, may not harm R. euryale, but could represent a threat to R. mehelyi, which would then be restricted to dense woodland, possibly competing with other bat species, including R. euryale. To conserve both species, the maintenance of a variety of wooded habitats of differing density is recommended.

“…Other small aerially hawking vespertilioniformids, including the sympatric population of New Zealand long-tailed bat Chalinolobus tuberculatus, have large home ranges in the order of hundreds or even thousands of hectares in cold temperate climates (e.g., O'Donnell, 2001;Fenton and Bo gdanowicz, 2002;Johnson et al, 2007;Hillen et al, 2009;Zeale et al, 2012). Recent research suggests food abundance and distribution are the key drivers of home range size, with range sizes being larger when food availability is limited, and variation in individual range sizes dependent on the differing foraging requirements of different age, sex and reproductive status (e.g., O'Donnell, 2001;Goiti et al, 2003Goiti et al, , 2006Almenar et al, 2011).…”

“…Further, Davy et al (2007) detected individuals several times in terrestrial habitats on Zakynthos Island, suggesting that M. capaccinii can forage over terrestrial habitats in extremely arid places such as the Ionian Islands. It is then possible that, under suboptimal conditions (Goiti et al 2003) or in dry seasons, bats modify their foraging behaviour, but the main conclusion for conservation purposes is that M. capaccinii fully depends on aquatic habitat in and around the breeding season.…”

“…Secondly, sound knowledge about the autoecology of M. capaccinii has been published only recently. The number of studies on diet (Aihartza et al 2003, Levin et al 2006, Biscardi et al 2007, Almenar et al 2008, factors affecting foraging behaviour, and the spatial range of foraging individuals is now remarkable (Almenar et al 2006, Biscardi et al 2007, Né-moz & Brisorgueil 2008, Aihartza et al 2008. Moreover, 2 of these are radiotracking studies with a significant number of individuals surveyed, 21 in Italy (Biscardi et al 2007) and 33 in France (Némoz & Brisorgueil 2008), which improves considerably the quality of available data on the foraging ecology of the species and thus allows a more comprehensive framework for conservation strategies to be proposed.…”

The main factors threatening Myotis capaccinii (Bonaparte, 1837) are considered to be foraging habitat degradation and roost loss. Conservation strategies that focus on the protection of roosts are feasible as long as direct threats by human activities are correctly identified. However, before protection of foraging habitat can be implemented more accurate information is required. We review the available information of relevance to foraging habitat management for the species. Three main topics are considered based on the results of a radiotelemetry study on 45 ind. in 3 seasons: habitat dependence, features of foraging habitat, and spatial range. M. capaccinii foraged almost completely over aquatic habitats as in other telemetry studies. We discuss the importance of terrestrial habitats and the dependence of the species on aquatic habitats. It has been proposed that several factors affect habitat selection in this species. The presence of smooth, clutter-free water surfaces seems to be the most important structural factor, but we found that prey richness also affected habitat selection. Effects of features related to riparian vegetation and water quality are thought to vary according to local conditions. Preference for wide water bodies is probably linked to preference for smooth surfaces, where detection and trawling of prey is favoured. As highlighted by recent telemetry studies, we observed M. capaccinii foraging at long distances from the roost. Therefore, the area of application for conservation measures should be large: we suggest a protection radius of 20 km around roosts.
