“…Recent bat records include threatened species whose distribution is still poorly known, such as Eptesicus taddeii (Miranda et al 2006, Miranda et al 2011, Bernard et al 2013, Rubio et al 2014.…”

This study aimed to utilize data of recent studies of bats surveying in the Atlantic Rainforest to evaluate the degree of knowledge of bat distribution in this biome. Data of new records or range extension of species published between 2010 and 2013 were compared among Brazilian biomes. We also utilized a case study in the Paraná State coastal area, southern Brazil, which was considered of low priority for bat inventories but had new records reported recently. The Atlantic Rainforest showed the highest number of papers with new information about bat distribution in Brazil. The number of bat species for this biome reaches 117. In the past 10 years, 11 new records have been reported for the Paraná State coastal area, increasing the bat richness by 33%. Our findings suggest that we do not know sufficiently the bat distribution across the Atlantic Rainforest. In such a hotspot for biodiversity conservation, it may be dangerous to establish low-priority areas for inventories, especially when an almost unique and biased survey method has been used.

“…To reassess the species conservation status, we used information on the level of rarity, EOO and AOO (IUCN, 2012). We included the level of rarity and the ecoregions the species inhabits to infer the conservation status of the species because of the absence of information on other factors that can influence the AOO, such as biotic interactions (predation, competition) and landscape (connectivity and shelter) (Bernard et al, 2013). We also examined whether the EOO or AOO of C. vestitus overlaps with protected areas, by using the protected areas layer for Colombia (October 2018; SINAP, 2018), and evaluated the per cent of forest area that remained unchanged during 2016–2017 within the polygon of the species range (IDEAM, 2018).…”

The brown hairy dwarf porcupine Coendou vestitus is a poorly studied Andean species endemic to Colombia. Its current Red List category is contradictory: globally it is categorized as Data Deficient but in Colombia it is categorized as Vulnerable. This contradiction has limited the implementation of conservation programmes. We evaluate the level of rarity of the species and provide consolidated information for a new assessment of its Red List status. We reviewed literature, photographs, and voucher specimens in natural history collections. Using the confirmed records, we estimated the extent of occurrence (EOO) based on the minimum convex polygon and the area of occupancy (AOO) summing the area of grid squares occupied by the species. We found that C. vestitus is very rare, with a small range, low estimated population density, occurrence in only one habitat type and small body size. The species has an EOO of 3,323 km2 and an AOO of 24 km2, based on six confirmed localities, all on the western slopes of the Eastern Cordillera, in the central Andean region of Colombia. Based on the species' rarity, restricted distribution, and threats to its natural habitat, we recommend its categorization as Endangered on the IUCN Red List. This will help delineate research and conservation efforts for this porcupine, which has a highly restricted range and inhabits the threatened Andean forest.

“…Mais uma vez esse fato pode apontar para uma biodiversidade ainda desconhecida, pois apesar de ser uma das regiões mais amostradas no Brasil, apenas 27% de sua área foi minimamente bem amostrada com relação aos morcegos (Bernard et al 2011a). Além da falta de conhecimento, essa biodiversidade que ainda não é conhecida pode já estar ameaçada, como foi constatado no caso de E. taddeii (Bernard et al 2013) e possivelmente D. capixaba, que também apresenta os poucos registros que tem em regiões fragmentadas e em alto risco (Nogueira et al 2012), o que reforça a necessidade de preservação das áreas referentes à esse padrão.…”

à Débora, que foi minha maior companheira durante esse tempo do mestrado. Obrigado por todo amor e carinho, e por ter me ensinado tanto sobre a vida e sobre os mistérios do universo. Aos amigos da vida, que me acompanham desde a infância, e não importa o quão diferentes sejam nossos caminhos estamos sempre conectados. Em especial aos companheiros Felipe Lenti e "Minu Grilo". Desde o começo da minha carreira, nossas conversas contribuíram muito para minha formação, e continuam sendo importantes até hoje. Desejo tudo de bom pra nós três nesses novos caminhos que a vida nos deu. Lembro aqui também dos grandes amigos e companheiros de tantas aventuras Vitinho, Lipe e Cadu, que teriam sido ótimos colegas biólogos, e que sempre me incentivaram muito neste caminho. Obrigado à professora Maria Julia, pela bolsa no começo do mestrado. Sua ajuda foi fundamental para a minha permanência no programa. Obrigado também a CAPES, que forneceu a bolsa durante o último ano do mestrado. Enfim, tudo isso só valeu a pena por causa dos bons momentos vividos. Eu faço isso pelo encontro com um bicho na floresta, pelo banho de cachoeira depois de um dia de campo, pela prosa com os amigos e com os nativos pelos interiores do Brasil. E por isso, os personagens mais importantes de toda essa caminhada são na verdade os ecossistemas, as paisagens, as espécies e os momentos bons que eu pude desfrutar durante esse período. Um agradecimento especial aos morcegos, por me deixarem invadir sua privacidade.
