Wings are the most obvious adaptation bats have for powered flight and differences in wing morphology are known to correlate with flight behaviour. However, the function(s) of ancillary structures such as the ears and tail, which may also play an important role during flight, are less well understood. Here we constructed a simplified model of a bat body with ears based upon morphological measurements of a brown long-eared bat (Plecotus auritus) to examine the aerodynamic implications of flying with large ears. The forces and moments produced by the model were measured using a sensitive 6-component force and torque balance during wind tunnel testing. The large ears of the model bat produced positive lift as well as positive drag of the same order of magnitude. At small ears angles (0° to 10°), increasing the angle of the ears resulted in an increase of the lift-to-drag ratio. At higher ear angles (> 10°) separation of the flow occurred which caused a large decrease in the lift-to-drag ratio produced. To maximise the benefit from the ears (i.e., lift-to-drag ratio) our model predicts that a horizontal free flying P. auritus should hold its ears at an approximate angle of 10°. The results of the pitching moment coefficient are inconclusive in determining if the large ears are important as flight control structures. The additional drag produced by the ears has consequences for the foraging behaviour of P. auritus with reductions in its flight speed and foraging range.

The study was carried out in central and north-eastern Poland in order to assess bat occurrence in small winter roosts located in house-cellars, in relation to the share of the surrounding landscape taken by forest cover and the distance separating the different sites from forests of at least 1 km². Data from single checks in 2243 cellars in 1990–2007 revealed a positive relationship (R² = 0.33, P <0.001) between the percentage of cellars occupied by bats and the forest cover (range: 2–58%) in sections of surrounding landscape covering between 30 and 220 km². Forest cover in the landscape within 1 km of the cellar appeared to have a slight influence on the number of species and species diversity (Simpson’s index; respectively R² = 0.14, P = 0.006 and R² = 0.13, P = 0.011). Both number of species and species diversity were progressively lower with increasing distance from the nearest forest covering an area of 1 km² or more (for both R² = 0.15, P = 0.005). Myotis nattereri (Kuhl, 1817) and Barbastella barbastellus (Schreber, 1774) were significantly more likely to colonise the cellars surrounded by landscape with a higher level of forest cover (P = 0.001 and 0.031), while M. nattereri was also more likely to be found in those at shorter distances from forests (P = 0.005). No such relationships were reported for either Plecotus auritus (Linnaeus, 1758) or Myotis daubentonii (Kuhl, 1817).

Habitat destruction and fragmentation caused by modern forestry and agriculture are some of the main problems for the long-term survival of many species. In this study, a bat community of 11 species was investigated with the objective to evaluate the impacts of patch size, distance between habitat patches and habitat quality on species number, and also to investigate the use of corridors. Habitat islands, varying in size from 0.1 to 98.7 ha, in an agriculture-dominated landscape were surveyed. Habitat use by four species; Myotis brandti (Eversmann, 1845), M. nattereri (Kuhl, 1818), Pipistrellus pipistrellus (Schreber, 1774), and Plecotus auritus (Linnaeus, 1758), was recorded in detail. In a stepwise multiple regression species number was found to be positively related to the area of deciduous woodland, but not to the area of coniferous forest or the distance to the continuous forest. Three of the four study species avoided all kinds of open habitats. Corridors were used as hunting habitats. Different hypotheses that might explain behaviour in open habitats are discussed.

We determined the foraging habitats of the northern batEptesicus nilssonii (Keyserling et Blasius, 1839), Brandt’s batMyotis brandtii (Eversmann, 1845), whiskered batMyotis mystacinus (Kuhl, 1819), Daubenton’s batMyotis daubentonii (Kuhl, 1819) and brown long-eared batPlecotus auritus (Linnaeus, 1758) in southern Finland. Among these species, we compared the diversities of foraging habitats, linear feature preference and the bats’ tendencies to forage simultaneously.Eptesicus nilssonii was the most opportunistic, foraging in a wide range of habitats.Myotis daubentonii (94%) foraged mainly on water habitats, whileM. brandtii/mystacinus (89%) andP. auritus (66%) foraged mainly in forest habitats. The diversities of foraging habitats used byE. nilssonii andP. auritus were higher than those ofM. brandtii/mystacinus andM. daubentonii. Both E.nilssonii andP. auritus foraged mostly alone or in small numbers, whileM. brandtii/mystacinus tended to gather in large numbers to forage in the same habitat. Half ofE. nilssonii and 46% ofM. daubentonii foraged over linear features, while other species did not use linear features to such an extent. Management and conservation of foraging habitats are needed especially forM. brandtii/mystacinus andM. daubentonii, which are more specialized thanE. nilssonii and P. auritus.
