“…In cities, these traits allow bats to travel longer distances between foraging sites and to avoid noise, lights, and other urban disturbances [26, 88]. Bats with urban adaptor traits were dominant in this study and in other urban bat studies (but see [23]). Second, urban bat communities appear to differ from taxa subject to biological homogenization such as birds [19], where urban communities often include non-native species, and are independent of regional diversity and more similar to distant urban communities than adjacent areas [89].…”

“…Our findings are also consistent with other studies reporting dominance of one species in urban areas: M . lucifugus [23], Eptesicus fuscus [32, 91, 92, 104–107], E . serotinus [25, 108], and Chalinolobus gouldii [12].…”

“…fuscus is known to forage above the canopy and in open areas [118], Dixon [91] found them to avoid impervious surfaces and open habitat in Minneapolis. Coleman & Barclay [23] speculated that the smaller size of insects in urban areas [119] could result in less attractive prey for E . fuscus , a larger bat than the dominant M .…”

Understanding how to manage biodiversity in urban areas will become increasingly important as density of humans residing in urban centers increases and urban areas expand. While considerable research has documented the shifts in biodiversity along urbanization gradients, much less work has focused on how characteristics of dense urban centers, effectively novel environments, influence behavior and biodiversity. Urban bats in San Francisco provide an opportunity to document changes in behavior and biodiversity to very high-density development. We studied (1) the distribution and abundance of bat foraging activity in natural areas; and (2) characteristics of natural areas that influence the observed patterns of distribution and foraging activity. We conducted acoustic surveys of twenty-two parks during 2008–2009. We confirmed the presence of four species of bats (Tadarida brasiliensis, Myotis yumanensis, Lasiurus blossevillii, and M. lucifugus). T. brasiliensis were found in all parks, while M. yumanensis occurred in 36% of parks. Results indicate that proximity to water, park size, and amount of forest edge best explained overall foraging activity. Proximity to water best explained species richness. M. yumanensis activity was best explained by reduced proportion of native vegetation as well as proximity to water. Activity was year round but diminished in December. We show that although bats are present even in very densely populated urban centers, there is a large reduction in species richness compared to that of outlying areas, and that most habitat factors explaining their community composition and activity patterns are similar to those documented in less urbanized environments.

“…The diversity decrease in urban areas compared to natural areas is common for bat populations in temperate zones (Coleman and Barclay, 2012). The full list of bat fauna of the region includes mostly forest-dwelling species that breed in woodland landscapes Gukasova, 2009a, 2010).…”

This study presents information about the year-round phenology of bats of temperate zones in a city area for the first time. In total, 967 individuals of 5 bat species (Nyctalus noctula [87.5%], Eptesicus serotinus [10.6%], Pipistrellus kuhlii [0.8%], Vespertilio murinus [0.9%], and Plecotus auritus [0.1%]) were recorded during 2013 in Kharkiv. The population structures of temperate bat species are complex; segregation of sex and age groups varies spatially and seasonally. Most of the bats (88%) were collected during the hibernation period (January-March and November-December) and the autumn invasion (August-mid-September). The breeding period saw a lower number of bats collected, making up 0.5% of records (May-July). The degree of tolerance to urbanization is species-specific. The bats were found indoors (68.6%), between window frames (26.6%), outdoors (2.8%), in basements (1.05%), and on balconies (0.95%). Bats of temperate latitudes inhabit big cities in significantly increasing numbers in winter, spring, and autumn. They avoid urban areas in both the breeding period and the period of fat-store accumulation before hibernation.

“…En los espacios verdes urbanos se registraron tres especies de murciélagos insectívoros y sólo un frugívoro, mientras que en los espacios verdes no urbanos se capturaron dos especies frugívoras y un insectívoro. El registro de un mayor Discusión número de especies de murciélagos insectívoros en los espacios verdes urbanos, de acuerdo a algunos autores, se debe básicamente a que algunas especies que pertenecen a este gremio alimentario presentan mayor actividad en zonas urbanas, al encontrar más cantidad o disponibilidad de alimento en dichas zonas (Ávila-Flores y Fenton 2005;Coleman y Barclay 2012).…”

Introduction:The demands of space for housing, industrial, commercial, and recreation space, are increasing as the human population continues to focus on urban areas. This implies an increase and constant degradation of natural environments. Despite the negative effect that the urban areas have on the biodiversity, these can be considered as important areas for the conservation of native flora and fauna. This is because urban areas have different types of land uses, where green spaces, represent an important component for the conservation of biological diversity. This study estimated the richness and abundance of rodents and bats in urban and non-urban green spaces in the city of San Cristobal de Las Casas (SCLC), Chiapas, Mexico. Given the great variety of types of green space in an urban area, the richness and abundance of rodents and bats in these areas will depend on the characteristics of the vegetation (richness and abundance of vegetal species) and the formation of the surrounding matrix (types of uses of soil around the green space). Methods:This study was conducted in 10 sites with presence of green spaces in the urban area and the periphery of SCLC. The rodents and bats were captured monthly from March to August 2013, for three consecutive nights per site. We compared the richness of species, relative abundance and diversity index between urban and non-urban green spaces.Results: There were a total of 12 species and 108 individuals, belonging to three families, Muridae, Phyllostomidae, and Vespertilionidae. In the non-urban green spaces were captured 55 individuals of four species of native rodents, and 19 individuals of three species of bats. In the urban green spaces were captured 11 individuals of three species of rodents (a species was native), and 23 individuals of four species of bats. For the richness of species of mammals, the correlation analysis showed very low values of relationship regarding to the independent variables. Discussion and conclusions:The number of species recorded in this study in the two groups of green spaces (urban and non-urban), show that these spaces can hold more than 40% of the total number of species recorded for the municipality of San Cristóbal de Las Casas. The capture of larger number of individuals of species of native rodents in the non-urban green spaces may be that in these areas there is greater availability of resources such as food, shelter and breeding sites, since these sites are part of a remnant of forest. In the case of bats, there were not significant differences in their diversity between urban and non-urban green spaces. This study found that the urban and non-urban green spaces in the interior and periphery of the city of SCLC, are important for the native fauna of rodents and bats. In this way, preserving green areas on the periphery of an urban landscape is decisive for the conservation of the native fauna of the region, since they are reservoirs of their diversity.
