“…Other bats often considered to be extinct have been recently rediscovered as living animals (e.g., Dobsonia chapmani, Myotis planiceps; see Simmons, 2005). Several mormoopid and phyllostomid species from the West Indies also became extinct during the Holocene and may have persisted into historical times, but as far as we know these taxa remain known solely from subfossil remains rather than historical museum specimens (Simmons, 2005; see also Tejedor et al, 2004Tejedor et al, , 2005.…”

Two new species of flying foxes (genus Pteropus) from the Samoan archipelago are described on the basis of modern museum specimens collected in the mid-19th century. A medium-sized species (P. allenorum, n. sp.) is introduced from the island of Upolu (Independent Samoa), based on a specimen collected in 1856 and deposited in the Academy of Natural Sciences of Philadelphia. It has not been collected again, and we regard it as almost certainly extinct. This species is smaller bodied and has much smaller teeth than both extant congeners recorded in the contemporary fauna of Samoa (Pteropus samoensis and P. tonganus). The closest relative of this new species may be Pteropus fundatus of northern Vanuatu. The disjunct historical distribution of these two smalltoothed flying foxes (in Vanuatu and Samoa) suggests that similar species may have been more extensively distributed in the remote Pacific in the recent past. Another species, a very large flying fox with large teeth (P. coxi, n. sp.), is described from two skulls collected in Samoa in 1839-1841 during the U.S. Exploring Expedition; it too has not been collected since. This robust species resembles Pteropus samoensis and Pteropus anetianus of Vanuatu in craniodental conformation but is larger than other Polynesian Pteropus, and in some features it is ecomorphologically convergent on the Pacific monkey-faced bats (the pteropodid genera Pteralopex and Mirimiri). On the basis of eyewitness reports from the early 1980s, it is possible that this species survived until recent decades, or is still extant. These two new Samoan species join Pteropus tokudae of Guam, P. pilosus of Palau, P. subniger of the Mascarenes, and P. brunneus of coastal north-eastern Australia as flying

“…During the late Pleistocene and early Holocene waves of extinction nearly obliterated this biota, but the majority of the bats survived (Dávalos and Turvey 2012). Bats were not traditionally hunted for food in the Caribbean, and many species have proven resilient in the face of introduced predators (although see Tejedor et al 2005). Although habitat changes (Pregill and Olson 1981) and competition (Koopman and Williams 1951;Williams 1952) have been proposed to explain extirpations of Caribbean bats since the Last Glacial Maximum (LGM), sea-level rise caused by nonanthropogenic climate change may be a more important driver of extinction in this fauna (Morgan 2001;Dávalos and Turvey 2012).…”

Ecological factors such as changing climate on land and interspecific competition have been debated as possible causes of postglacial Caribbean extinction. These hypotheses, however, have not been tested against a null model of climate-driven postglacial area loss. Here, we use a new Quaternary mammal database and deep-sea bathymetry to estimate species–area relationships (SARs) at present and during the Last Glacial Maximum (LGM) for bats of the Caribbean, and to model species loss as a function of area loss from rising sea level. Island area was a significant predictor of species richness in the Bahamas, Greater Antilles, and Lesser Antilles at all time periods, except for the Lesser Antilles during the LGM. Parameters of LGM and current SARs were similar in the Bahamas and Greater Antilles, but not the Lesser Antilles, which had fewer estimated species during the LGM than expected given their size. Estimated postglacial species losses in the Bahamas and Greater Antilles were largely explained by inferred area loss from rising sea level in the Holocene. However, there were more species in the Bahamas at present, and fewer species in the smaller Greater Antilles, than expected given island size and the end-Pleistocene/early Holocene SARs. Poor fossil sampling and ecological factors may explain these departures from the null. Our analyses illustrate the importance of changes in area in explaining patterns of species richness through time and emphasize the role of the SAR as a null hypothesis in explorations of the impact of novel ecological interactions on extinction.

“…Estas decisões foram tomadas baseadas principalmente em revisões e na argumentação expressa em trabalhos publicados, na consulta direta a especialistas, ou ainda baseadas no nosso melhor discernimento. Neste processo de escolha, a nomenclatura dos registros aqui adotados seguiu Simmons (2005), com exceções de Vampyressa brocki e Vampyressa bidens, aqui tratadas como Vampyriscus (veja Baker et al 2003), de Natalus, cujos registros previamente atribuídos a N. stramineus para o Brasil reconhecemos como N. espiritosantensis (Tejedor 2006, Tejedor et al 2005, de Platyrrhinus, em função de significativas revisões recentes e descrições de novas espécies para o gênero (Velazco 2005, Velazco & Gardner 2009, Velazco & Patterson 2008, Velazco et al 2010), e incluindo ainda Artibeus planirostris e não A. jamaicensis como espécie válida para a Amazônia Brasileira (Lim et al 2004, Tavares et al 2008), e Mimon cozumelae como sinônimo júnior de M. bennettii (mas veja Gregorin et al 2008). Outros esclarecimentos sobre mudanças nomenclaturais desde Simmons (2005) podem ser obtidos em Gardner (2008) e Tavares et al (2008).…”

Brazil holds nearly 15% of world's bat species richness, and most of it is present in the Amazonian biome. Here we present an updated compilation of bat species for the Brazilian Amazonia, with records of 146 species, belonging to nine families and 64 genera. At least 46 of those species are currently restricted to the Amazonian biome. Pará State is the species richest (120 spp.) and the Amazonian portion of Maranhão the least (21 spp.). Nine species were recorded in all the Amazonian States, and 28 are restricted to a single state. The species list for the region is not yet completed and is very likely that the Brazilian Amazonia holds more than 160 species of bats. We indicated priority areas for inventories in the region, and discuss some factors that can contribute to a further increase in the knwoledge of the regional bat fauna. Keywords: Amazônia Legal, bat species richness, biodiversity inventories.BERNARD, E., TAVARES, V.C. & SAMPAIO, E. Compilação atualizada das espécies de morcegos (Chiroptera) para a Amazônia Brasileira. Biota Neotrop. 11(1): http://www.biotaneotropica.org.br/v11n1/pt/ abstract?article+bn00611012011.Resumo: O Brasil abriga cerca de 15% da riqueza de morcegos do planeta, e grande parte desta riqueza está presente no bioma Amazônia. Apresentamos aqui uma compilação atualizada das espécies de morcegos da Amazônia Legal Brasileira, com registros formais de 146 espécies, distribuídas em nove famílias, e 64 gêneros. Pelo menos 46 destas espécies têm, até o momento, a ocorrência restrita ao bioma amazônico. O Pará é o estado com o maior número de espécies registradas (120), enquanto que a porção amazônica do Maranhão apresenta apenas 21 espécies. Nove espécies foram registradas em todos os estados amazônicos e 28 são conhecidas em apenas um estado. A lista de espécies de morcegos para a região não está esgotada e é bastante plausível que a Amazônia Brasileira contenha mais de 160 espécies de morcegos. Apontamos áreas prioritárias para a realização de inventários para morcegos na região, e discutimos alguns fatores que podem contribuir para o aumento do conhecimento da quiropterofauna amazônica. Palavras-chave: Amazônia Legal, riqueza de espécies de morcegos, inventários de biodiversidade.
