“…Many investigations have reported occurrence and distribution range extensions for felids in the Brazilian Atlantic Tropical Forest, based on footprint identification [18, 33–39, 43, 55–56] from different field identification guides ( e.g. , [3, 9, 22–24, 57–59]).…”

Carnivores, particularly felids, face threats in many regions of the world. They are a crucial component of biodiversity with a functional role in the top of the food chain. Therefore, they have been the target of surveys and monitoring and ecological studies, most of which are based on footprint identifications, an efficient and low-cost method compared to other approaches. In these cases, species identifications may suffer from a high degree of bias due to the overlap in the size and shape of footprints among species. We experimented with small to medium captive wild felids of five species: ocelot, Leopardus pardalis, margay L. wiedii, oncilla, L. guttulus, domestic cat, Felis catus, and jaguarondi, Puma yagouaroundi). We tested for differences in footprint measurements, including main pad and toe pad sizes. We used humid sand as substrate and took measurements from several front and hind footprints of seven animals per species (except jaguarondi, for which only four animals were available). Our results showed that ocelot is the only species for which it is possible to obtain 100%-accurate footprint identifications, mainly because of its footprint area ( i.e., length × width). The remaining species presented a wide variation in measurements, making them almost impossible to distinguish based solely on footprint dimensions. Our results suggest that researchers should restrict identification to the genus level or adopt a multidisciplinary sampling strategy by combining footprint detection with camera-trapping, visual observation, scat collection, molecular ecology techniques, and/or face-to-face interviews with local residents.

Foram avaliadas a magnitude, composição e padrões da mortalidade de vertebrados silvestres, a partir da colisão com veículo em estradas no Cerrado. Mesmo sendo próximas, estas diferem no tempo em que estão pavimentadas, volume de tráfego, paisagem e qualidade da cobertura asfáltica. Quatro trechos de 70 km de extensão localizados no Cerrado do sudoeste do estado de Mato Grosso foram amostrados mensalmente em junho de 2009 a maio de 2010, por dois observadores em um veículo com velocidade média de 40km/h. Sendo percorridos 840km por rodovia e 2.520km no total. Quando as carcaças eram avistadas o veículo era parado para que os dados sobre o animal fossem amostrados. Os dados de riqueza de espécies, número de indivíduos atropelados e por característica de faixa central da rodovia foram submetidos aos testes de Shapiro-Wilk, para testar normalidade, e ao de Bartlett para testar homocedasticidade. Para os dados que não apresentaram normalidade e/ou homocedasticidade, foi utilizado o teste não paramétrico de Kruskall-Wallys associado ao teste LSD. Onde os dados apresentaram os pressupostos de normalidade e homocedasticidade dos resíduos, foi realizado Anova (one way) juntamente com o teste de Tukey para averiguar diferenças entre os resultados obtidos. Foram registradas 483 mortes de 108 spp. Dos indivíduos atropelados nestas quatro rodovias, 7% são anfíbios, 15% répteis, 11% aves e 67% de mamíferos. Este trabalho apresenta dados suficientes para que medidas sejam tomadas nas rodovias que apresentaram altos índices de atropelamento, detectando quais espécies são mais afetadas, com isso se tem dados suficientes que embasem tomadas de decisão com o intuito de conservar a fauna silvestre.

“…More than half of recorded species were aerial insectivores (Vespertilionidae and Molossidae). These bats tend to be rare in studies that used mist (Miretzki 2003); PAL=Palmas municipality (Miranda et al 2008), GUA=Guarapuava municipality (Valle et al 2011); and PMNA=Parque Municipal Natural das Araucárias; Guarapuava municipality (Miranda & Zago 2015).

“…To analyze the dissimilarities between the seven localities and evaluate possible nestedness or turnover processes involved in the community assembly, we calculated the beta diversity (BD) and its components: beta diversity nestedness (BD nest) and beta diversity turnover (BD turn ). This (Miranda et al 2008), GUA=Guarapuava municipality (Valle et al 2011); and PMNA=Parque Municipal Natural das Araucárias; Guarapuava municipality (Miranda & Zago 2015). analysis was done using the Sorensen dissimilarity index and the Baselga (2010) approach with the R package betapart (Baselga et al 2017).…”

“…After that, Miretzki (2003) recorded some species in the same region in a review of Paraná's bat fauna. More recently, a few mammalian surveys were conducted (Miranda et al 2008, Valle et al 2011, while the first survey focused uniquely on bats was undertaken between 2012 and 2013 (Miranda & Zago 2015). Since 2013, no surveys have been performed in the region to the best of our knowledge.…”

Here, we present an updated list of bats from Guarapuava highlands, center-southern of Paraná state, southern Brazil. This species list is based on four literature records (secondary data) and data from fieldwork (primary data) in three localities. All species recorded (primary and secondary data) were evaluated by the relative frequency and their conservation status were assessed. The species recorded from fieldwork were also evaluated by relative abundance. A beta diversity analysis was done to verify dissimilarities in the bat fauna among the seven localities. We recorded 28 species in the Guarapuava highlands (14 Vespertilionidae, 10 Phyllostomidae and 4 Molossidae), of which, eight are new records for the region. Sturnira lilium was the most abundant in three localities (primary data), and the most frequent species in all studies (primary and secondary data). Only four species were classified globally as "Near Threatened" or "Data Deficient", nevertheless they were frequent in this region. The mean regional beta diversity was 0.72, what could be mostly explained by turnover (0.64) rather than by nestedness (0.08). The greatest species richness of the family Vespertilionidae is a common pattern in subtropical and temperate regions as in highlands and mountains. As turnover was the main component of the beta diversity, the communities seemed to be structured mainly by replacement of species among the studied localities. The Guarapuava highlands present a diverse bat fauna, however, this region requires more sampling effort to become well known.
