“…A maior parte dos estudos se concentra no sul e sudeste do país, com enfoque na riqueza e a abundância de morcegos existentes nos fragmentos e como essas variáveis estão relacionadas com o tamanho da área e as características ambientais do fragmento e da matriz circundante (Pedro et al, 1995;Reis e Muller, 1995;Reis et al, 2000;Félix et al, 2001;Barros et al, 2006;Carvalho et al, 2009). Outras abordagens ecológicas também procuram avaliar a capacidade das espécies em superar as distâncias existentes entre os fragmentos (Bianconi et al, 2006;Costa et al, 2006;Menezes et al, 2008), além de medir variações nas diversidades de morcegos que utilizam a borda e o interior de fragmentos de diferentes tamanhos (Faria, 2006).…”

Devido ao desmatamento, a fragmentação fl orestal é uma realidade cada vez mais presente no oeste do estado do Acre. O estudo objetivou avaliar variações na riqueza e abundância de morcegos em um fragmento fl orestal urbano de aproximadamente 150ha localizado na cidade de Rio Branco (AC). As coletas foram realizadas em dois sítios: sendo dois pontos de coleta a 200m da borda e outros dois a 20m da borda. Redes de neblina fi caram abertas quatro horas depois do pôr-do-sol, durante três noites/mês. O índice de diversidade de Shannon-Wiener (H') e o índice de similaridade de Jaccard (J) foram usados para análise comparativa. Durante 48 noites (novembro/2005-julho/2007) foram capturados 85 morcegos de 15 espécies, com maior riqueza e abundância de quirópteros no interior do fragmento. A similaridade de espécies foi baixa (J=0,44), indicando preferência de habitat. O índice de diversidade encontrado (H'=2,091 nats/indiv) foi similar a de outros estudos na Amazônia, com menor diversidade na borda (H'=1,864) do que no interior do fragmento (H'=2,047). Carollia perspicillata (n=32) e Artibeus lituratus (n=13) responderam por 57,6% do total de capturas. As características da matriz e a adaptação dos morcegos às redes explicam os valores encontrados.

“…Phyllostomids dominated our captures (97%); these bats have special echolocation and morphological adaptations to fly in cluttered environments (Kalko, ; Stockwell, ); thus, live fences may offer a familiar environment for leaf‐nosed bats to move across disturbed areas. The most common Phyllostomids that we captured ( Carollia perspicillata and Artibeus jamaicensis ) can travel large distances and have low fidelity to local forest patches (Bianconi, Mikich, & Pedro, ; Menezes‐Jr et al, ; Morrison, ) making them more adaptable to altered landscapes. However, C. perspicillata and A. jamaicensis benefitted from live fences.…”

Linear features can benefit wildlife by assisting animal movement. We captured bats along barbed‐wire and live‐tree fences connecting tropical dry forest patches in Nicaragua. Bat species richness and captures were higher along live fences but we noted differences in sex ratios, richness, and species composition compared to surrounding natural forests.

“…This can explain why few records of these species were observed. The majority of our roadkill records is from A. lituratus (46%), a frugivore phyllostomid adapted to explore open areas and to move across great distances (Passos & Passamani 2003, Barros et al 2006, Menezes et al 2008, Reis et al 2012.…”

Road and Landscape Features That Affect Bat Roadkills in Southeastern Brazil

et al. 2017

The most studied impact on road ecology is roadkill, however, there is little information about the relations between highways and specific groups like bats. This study intended to identify the species of bats roadkilled and to evaluate the existence of temporal fluctuation between the roadkill rates, specific stretches of the road with higher rates, and characteristics of the road/landscape that may influence those rates. We encountered at least nine bat species among 65 roadkills (most Phyllostomidae), which comprise a subgroup of the local fauna that presents ecologic features that make them susceptible to being hit, especially Artibeus lituratus. The medium roadkill rate was of 0.01 individuals/km/day of monitoring, and there was no significant temporal variation. We identified five hotspots through special 2D HotSpot Identification Analysis. The selection of theoretical models through Generalized Linear Models showed that roadkill occurrence has a positive relation with vehicular traffic and negative relation with presence of marginal pasture and forests. As the major part of records was of species that are tolerant to human-disturbances, the increase in traffic consequently affected a higher number of bats capable to explore the area occupied by the road. The presence of native forest close to the road can lead to a decrease of animals hit by vehicles, once it offers more resources and favorable habitats, which reduces the need for bats to cross the roads for foraging. On the other hand, many species that necessarily depend on areas sheltered by trees for shelter, and do not possess the ability to fly long distances do not occur in open areas such as pastures. In this context, we suggest that the main measure of mitigation regard bat species would be the traffic control through speed limit, especially on the roadkill hotspots areas.
