Artibeus amplus Handley, 1987 is a little-known bat species endemic to northern South America. There are confirmed records of the species for Colombia, Venezuela, Guyana, and Suriname. In this study, we report the occurrence of A. amplus in Brazil based on the collection of two specimens captured in the municipalities of Cantá and Caracaraí in the state of Roraima. We also found a museum specimen from the state of Amazonas. The specimens were identified based on morphology and mitochondrial Cytochrome b gene analysis. After this contribution, the number of bat species in Brazil is 182. Surveys in other areas in the north of the country, such as the state of Pará, in addition to a comprehensive review of museum specimens, is needed to investigate the distribution of the species in areas where it has not been found yet.

Eptesicus Rafinesque, 1820 is widely distributed in the Old and New World (26 species), and Histiotus Gervais, 1856 is a South American endemic (11 species). Molecular phylogenies have recovered Eptesicus (sensu lato) as polyphyletic, with New World Eptesicus and the sister genus Histiotus in a paraphyletic American clade sister to Old World Eptesicus. Based on these phylogenetic reconstructions, authors have treated Histiotus as either a subgenus of Eptesicus or restricted Eptesicus to the New World species, treating Histiotus as a full genus, and using the name Cnephaeus Kaup, 1829 at the generic rank to comprise Old World Eptesicus. Based on recently published molecular studies, and on novel qualitative and quantitative morphological comparisons of representatives of Histiotus and New and Old World Eptesicus, we provide evidence for restricting the name Eptesicus to the species E. fuscus (Palisot de Beauvois, 1796) and E. guadeloupensis Genoways & Baker, 1975, allocating the remaining New World species under a new genus, keeping Histiotus as a full genus, and raising Cnephaeus to generic rank to comprise all Old World taxa currently under Eptesicus. This arrangement resolves the paraphyly of New World Eptesicus, and promotes taxonomic stability for Histiotus, which is a well-established genus of easily recognizable Neotropical bats and treated separate from Eptesicus by most authorities.

Bats are important for the homeostasis of ecosystems and serve as hosts of various microorganisms including bacteria, viruses, and fungi with pathogenic potential. This study aimed to isolate fungi from biological samples obtained from bats captured in the city of Sinop (state of Mato Grosso, Brazil), where large areas of deforestation exist due to urbanization and agriculture. On the basis of the flow of people and domestic animals, 48 bats were captured in eleven urban forest fragments. The samples were processed and submitted to microbiological cultures, to isolate and to identify the fungal genera. Thirty-four (70.83%) of the captured bats were positive for fungi; 18 (37.5%) and 16 (33.33%) of these bats were female and male, respectively. Penicillium sp., Scopulariopsis sp., Fusarium sp., Aspergillus sp., Alternaria sp., Cryptococcus sp., Trichosporon sp., and Candida sp., which may cause opportunistic infections, were isolated. The bat species with the highest number of fungal isolates was Molossus molossus: 21 isolates (43.8%). According to our results, bats captured in urban forest fragments in Sinop harbor pathogenic fungi, increasing the risk of opportunistic fungal infections in humans and domestic animals.


Os morcegos apresentam grande importância na homeostasia dos ecossistemas e são hospedeiros de uma rica diversidade de micro-organismos como bactérias, vírus e fungos com potencial patogênico. Portanto, este estudo visou isolar fungos presentes em amostras biológicas de morcegos na cidade de Sinop - MT, que possui grandes áreas de desmatamento devido à urbanização e agricultura. Foram capturados 48 morcegos de diferentes espécies, em onze fragmentos florestais urbanos definidos de acordo com fluxo de pessoas e animais domésticos, para obtenção de amostras biológicas. Essas amostras foram processadas e submetidas aos cultivos microbiológicos, para isolamento e identificação dos gêneros dos fungos. Dos 48 morcegos, 34 (70,83%) foram positivos para pelos menos um gênero de fungo, sendo 18 (37,5%) fêmeas e 16 (33,33%) machos, e os gêneros isolados a partir das amostras biológicas foram Penicillium sp., Scopulariopsis sp., Fusarium sp., Aspergillus sp., Alternaria sp., Cryptococcus sp., Trichosporon sp. e Candida sp., que podem ser causadores de infecções oportunistas. Desse total, a espécie que apresentou maior positividade para pelo menos um gênero de fungo foi Molossus molossus com 21 (43,8%). Nossos resultados demonstram que os morcegos capturados nos fragmentos florestais urbanos na cidade de Sinop - MT, podem atuar como agentes veiculadores de fungos com potencial patogênico, aumentando assim o risco de exposição e aquisição de infecções fúngicas oportunistas por pessoas e animais domésticos.

Resumo

Reserva Ecológica de Guapiaçu (REGUA) is a private, protected area inside a remnant of the Atlantic Forest with high biodiversity. Although the bats of the reserve have been sampled for more than two decades, few studies have been published about them. Based on a compilation of data from several surveys, we present an updated list of the bat species there and compare it with surveys from other locations in the Atlantic Forest. From August 1998 to September 2021, at least 194 sampling nights were carried out at REGUA by different research groups from various institutions, totaling 448,092 m2.h of sampling. A total of 4,069 individuals were captured, belonging to 47 species and six families. Additionally, our results indicate that it is possible that some species that occur at REGUA have not been recorded yet. REGUA has the greatest number of bat species known for the Atlantic Forest. This most likely results from the fact that the reserve includes large areas of mature, continuous forest connected with other protected areas in the State of Rio de Janeiro. Another factor contributing to the high diversity of bat species at REGUA is that the area has been intensely sampled for many years. Given that the bat assemblage there appears to be a good proxy to ascertain the ecological patterns of biodiversity in well-preserved forests, we consider REGUA to be an important area for long-term ecological research. The basic knowledge about the ecological interactions of bats with different food resources and zoonotic microorganisms offers a unique opportunity to carry out research in several areas of knowledge, making it possible to address questions about bat assemblage structure, bat-parasite ecology, competition, niche partitioning, and other related studies.

The order Chiroptera is the second largest group of mammals with bats being identified as reservoir of several viral zoonoses, although, little is known about their role in other groups of pathogens, including hemotropic Mycoplasma spp. To date, hemoplasma species have been found infecting several species of bats with high genetic diversity between 16S rRNA gene sequences. On this study, we aimed to identify the occurrence and characterize 16S and 23S rRNA genes of hemoplasma species in four bats species (Artibeus lituratus, Carollia perspicillata, Sturnira lilium and Sturnira tildae) from forest fragments in Paraná State, southern Brazil, using PCR-based assays. Spleen tissue samples were collected, DNA extracted and further screened by a pan hemoplasma PCR assay. All samples consistently amplified the mammal endogenous gapdh gene. One out of 15 (6.66%; 95% CI: 0.2-31%) bats tested positive for hemotropic Mycoplasma sp. by the PCR assay targeting the 16S rRNA gene. Sequencing of the 16S rRNA gene fragment from the hemoplasma-positive bat showed 99.14% identity with hemotropic Mycoplasma sp. detected in Sturnira parvidens from Belize. Sequencing of the 23S rRNA gene fragment from the hemoplasma-positive bat showed 86.17% identity with 'Candidatus Mycoplasma haemosphiggurus' detected in orange-spined hairy dwarf porcupines (Sphiggurus villosus) from Southern Brazil.(AU)


A ordem Chiroptera é considerada a segunda maior ordem de mamíferos do mundo, sendo os morcegos identificados como reservatórios de diversas zoonoses de origem viral, contudo, pouco se sabe sobre seu papel em outros grupos de patógenos, incluindo Mycoplasma spp. Até o momento, Mycoplasma sp., foi encontrado infectando várias espécies de morcegos ao redor do mundo, com alta diversidade genética entre sequências de genes 16S rRNA. O objetivo do presente estudo foi detectar a infecção por hemoplasmas em quinze morcegos insetívoros de quatro diferentes espécies (Artibeus lituratus, Carollia perspicillata, Sturnira lilium and Sturnira tildae) provenientes de fragmentos florestais dos municípios de Mandaguaçu, Maringá e Paiçandu, no Estado do Paraná, sul do Brasil. Amostras de tecido foram coletadas e o DNA extraído, para posterior análise por PCR para detecção de hemoplasmas. Todas as amostras amplificaram o gene gapdh. Um morcego, do total de 15 (6.66%; 95% CI: 0.2-31%), foi positivo para Mycoplasma sp. na análise do gene16S rRNA. O sequenciamento deste fragmento genético mostrou 99,14% de identidade com Mycoplasma sp. detectado em Sturnira parvidens em Belize. O sequenciamento do fragmento do gene 23S rRNA do morcego positivo mostrou 86,17% de identidade com 'Candidatus Mycoplasma haemosphiggurus' detectado em ouriço-cacheiro (Sphiggurus villosus) no sul do Brasil.(AU)

Myotis atacamensis (Lataste, 1892) was described based on three syntypes from San Pedro de Atacama, Chile. The type series is lost. The original description was based on few external and cranial characters, and the diagnosis became obsolete and useless considering the current diversity of South American Myotis. Based on 12 specimens of M. atacamensis from southern Peru and northern Chile, we provide a morphological comparison with its South American congeners, designate a neotype, and provide a new diagnosis.(AU)

Abstract New World bats are involved in key ecological processes and are good indicators of environmental changes. Recently, trait-based approaches have been used in several taxa to better understand mechanisms underlying species assemblages, biotic interactions, environmental relationships and ecosystem functions. However, despite the relevance of bats on ecosystem dynamics, so far, there is no conceptual framework that relies on the measurement of bat traits to address functional studies. Here, we present a set of 50 bat biological traits, which are suitable to assess environmental stressors and can potentially affect ecological processes. Several examples were provided to show the applicability of this framework in the study of Neotropical bat ecology. We suggest some considerations regarding trait-based approach including the importance of intraspecific variation, correlations between traits, response-effect framework, global dataset, and future directions to assess the reliability of functional relations across species and Neotropical regions by using traits. This could be helpful in tackling ecological questions associated with community assembly and habitat filtering, species diversity patterns along environmental gradients, and ecological processes. We envision this paper as a first step toward an integrative bat functional trait protocol held up with solid evidence.

Abstract Restingas are coastal ecosystems associated with the Atlantic Forest. They are threatened by habitat degradation and forest fragmentation due to intense human occupation. Many restingas have coastal lagoons formed by bay sedimentation of bays, the presence of river estuaries, or emerging groundwater. The distance between lagoons and the ocean influences the biotic community in them. This study aimed to compare the diversity (composition, abundance and richness) of bat communities associated with three lagoons within the Paulo Cesar Vinha State Park, Espírito Santo state. Two lagoons (Feia and Vermelha lagoons) are 2 km away from the ocean, while the third (Caraís lagoon) is just a few meters distant from the ocean. Species composition did not differ among the lagoons. Abundance of Carollia perspicillata and Glossophaga soricina was higher in the Caraís lagoon. Abundance of Artibeus lituratus and Platyrrhinus lineatus was higher in the Vermelha lagoon. Species with higher abundance in the Vermelha are usually associated with urban and disturbed environments. Vermelha lagoon is closer to human settlements and this could be a major driver of bat species abundance associated with this lagoon instead of distance from the ocean. These results may be used to guide conservations efforts in the restingas or habitats associated with restingas.

The flying fox (Pteropus giganteus) also familiar with the name of the greater Indian fruit Bat belongs to the order Chiroptera and family Pteropodidae. Current research emphasis on the DNA barcoding of P. giganteus in Azad Jammu Kashmir. Bat sequences were amplified and PCR products were sequenced and examined by bioinformatics software. Congeneric and conspecific, nucleotide composition and K2P nucleotide deviation, haplotype diversity and the number of haplotypes were estimated. The analysis showed that all of the five studied samples of P. giganteus had low G contents (G 19.8%) than C (27.8%), A (25.1%) and T (27.3%) contents. The calculated haplotype diversity was 0.60% and the mean intraspecific K2P distance was 0.001% having a high number of transitional substitutions. The study suggested that P. giganteus (R=0.00) do not deviate from the neutral evolution. It was determined from the conclusion that this mtDNA gene is a better marker for identification of Bat species than nuclear genes due to its distinctive characteristics and may serve as a landmark for the identification of interconnected species at the molecular level and in the determination of population genetics.(AU)


A raposa-voadora (Pteropus giganteus), também conhecida como morcego indiano, pertence à ordem dos Chiroptera e à família Pteropodidae. A presente pesquisa dá ênfase ao código de barras de DNA de P. giganteus em Azad Jammu e Caxemira. Sequências genéticas dos morcegos foram amplificadas, e os produtos de PCR foram sequenciados e examinados por software de bioinformática. De espécies congenérica e coespecífica, foram estimados composição nucleotídica e desvio de nucleotídeos K2P, diversidade de haplótipos e número de haplótipos. A análise mostrou que todas as cinco amostras estudadas de P. giganteus apresentaram baixos teores de G (19,8%) em comparação com C (27,8%), A (25,1%) e T (27,3%). A diversidade de haplótipos calculada foi de 0,60%, e a distância média intraespecífica de K2P foi de 0,001%, com um elevado número de substituições transicionais. O estudo sugeriu que P. giganteus (R = 0,00) não se desviou da evolução neutra. É possível concluir que o gene mtDNA é um marcador favorável para identificação de espécies de morcegos do que genes nucleares por causa de suas características distintivas e pode servir como um marco para a identificação de espécies interconectadas em nível molecular e para a determinação genética de populações.(AU)

Resumo

In Honduras, most bat inventories have been carried out with mist nets as the main sampling method, skewing knowledge towards the Phyllostomidae family, therefore the diversity and distribution of insectivorous bats is underrepresented. In order to have a more complete knowledge of the diversity of bats in the municipality of Yuscarán and mainly in the Yuscarán Biological Reserve, an inventory was carried out using the techniques of mist-netting and acoustic monitoring. The samplings were carried out between 910 and 1,827 m.a.s.l., covering agroecosystems, broadleaf forest, pine forest and urban environment. A total of 32 species of bats were registered, which represents 28% of the species diversity present in Honduras. Species belonging to five families were recorded: Emballonuridae (6.25%), Mormoopidae (15.22%), Phyllostomidae (56.25%), Molossidae (9.37%) and Vespertilionidae (12.5%). With the mist nets, a sampling effort of 7,128 m²/h was reached, which allowed the capture of 20 species and 186 individuals. Through the acoustic method, with 84 h/r, 13 species of insectivorous bats were recorded. The values of the acoustic parameters analysed from the search phase of each insectivorous species are provided, which can serve as a reference for the identification of species from Hondurans. To advance our understanding of the distribution patterns, composition, and vocal signatures of insectivore bats, we suggest the complementary use of mist nets and acoustic recorders in the inventories.(AU)

We evaluated the structure of a community of frugivorous bats using composition and abundance patterns, niche amplitude and food overlap of these animals in four Atlantic Forest fragments, each one exposed to different conservation realities. For twelve months, we captured six bat species and found the seeds of 13 species of pioneering plants in 158 fecal samples. The most abundant bat species were Artibeus planirostris (25.4%), Artibeus lituratus (24.1%) and Carollia perspicillata(23.9%). Only one fragment (Fazenda Unida), the most conserved area, exhibited a significantly different composition and abundance of species. We found low trophic niche amplitude values (<0.60), associated to high food overlaps. Our results suggest that bats can adjust their foraging strategy to deal with food availability variations. By favoring pioneering plant species, the fragmentation process noted of the studied areas creates an attractive environment for bats more tolerant to this type of disturbance. The sampled areas represent important secondary forest remnants in southern Brazil that require attention to avoid an even greater loss of bat diversity.
