“…There have been few studies of species-area relationships in bats, particularly in temperate regions. Although bat species richness increases with island area in Scandinavia and the Lesser Antilles (e.g., Ahlén 1983; Ricklefs and Lovette 1999;Pedersen et al 2003), the effect of forest patch size (i.e., forest islands) on bat species is equivocal. Lesiński et al (2007) found that bat species richness increased with forest patch size but that significant increases in species richness did not occur in patches >100 ha.…”

Urbanization and development are predicted to increase considerably in the United States over the next several decades, and this is expected to result in large-scale habitat loss, fragmentation and loss of wildlife species. Thus, natural parks and preserves are becomingly increasingly important in the conservation of regional biodiversity. We used mist-nets and AnabatII acoustic detectors to survey bats in 10 national parks in the southeastern U.S. and examined the relationship between bat community structure and development in the surrounding 5 km. We predicted that species richness would increase with park size and that species richness and evenness would decrease with development. Species richness was not related to development or any other landscape characteristics including park size. In contrast, species evenness declined with increasing development. Percent Developed land in the surrounding 5 km area was the only variable that entered into the stepwise regression model. The decrease in species evenness in the urban parks was due to the dominance of big brown bats (Eptesicus fuscus) in these parks. The percentage of big brown bats in our captures was positively related to percent Developed land in the surrounding area. Our data suggest that urban parks may be important for conserving regional bat biodiversity. However, the low species evenness in these parks suggests that some bat species may be susceptible to the effects of urbanization and may be extirpated over time. Thus, management of urban as well as rural parks should strive to conserve as much bat roosting and foraging habitat as possible.

“…Therefore, species accumulation curves are essential tools for assessing inventory completeness and should be graphed against suitable measures of sampling effort (e.g., numbers of captures) (Simmons and Voss, 1998). For Montserrat, our species accumulation curve peaked in the vicinity of 1,000 captures and 100 NN -values that are similar for many islands in the immediate region: Saint Kitts, Nevis, Antigua, and Saint Martin (Pedersen et al, 2003Genoways et al, In press). Without longduration/multi-year survey efforts, biodiversity estimates and conservation guidelines can only be approximations at best and almost certainly underestimate the true faunal diversity of an island.…”

“…Despite our own extensive survey efforts throughout the Caribbean , 2001Pedersen et al, 1996Pedersen et al, , 2003Pedersen et al, , 2005Pedersen et al, , 2006Pedersen et al, , 2007Pedersen, 2001;Larsen and Pedersen, 2002;, we too have neglected this critical aspect of bat survey work. However, two studies in the last few years used infrared lights and video cameras to specifically record bat interactions with the net (Lang et al, 2004;MacCarthy et al, 2006) and the efforts of Lang et al (2004) provided the incentive for employing a similar technique in an attempt to re-evaluate the last ten years of our own mist net data collected on Montserrat.…”

“…The chiropteran fauna of Antigua, Lesser Antilles was recently described after a mist net survey in a variety of habitats (1998)(1999)(2000)(2001)(2002)(2003) and after a thorough search and examination of museum voucher specimens from previous survey and collection efforts (Pedersen et al 2003). The chiropteran fauna of Antigua consists of seven species of bats: two frugivores, Artibeus jamaicensis and Brachyphylla cavernarum; one nectarivore, Monophyllus plethodon; one carnivore, Noctilio leporinus; and three insectivores, Natalus stramineus, Molossus molossus, and Tadarida brasiliensis.…”
