ABSTRACT
ABSTRACT The SISBIOTA-BRASIL was a three-year multimillion-dollar research program of the Brazilian government to document plants and animals in endangered/understudied areas and biomes in Brazil. Distributional patterns and the historical events that generated them are extensively unknown regarding Brazilian fauna and flora. This deficiency hinders the development of conservation policies and the understanding of evolutionary processes. Conservation decisions depend on precise knowledge of the taxonomy and geographic distribution of species. Given such a premise, we proposed to research the diversity of Diptera of the Brazilian western arc of Amazon, Cerrado, and Pantanal in the states of Mato Grosso, Mato Grosso do Sul, and Rondônia. Three important biomes of the South American continent characterize these Brazilian states: Amazon forest, Cerrado (Brazilian Savannah), and Pantanal. Besides their ecological relevance, these biomes historically lack intensive entomological surveys. Therefore, they are much underrepresented in the Brazilian natural history collections and in the scientific literature, which is further aggravated by the fact that these areas are being exponentially and rapidly converted to commercial lands. Our project involved over 90 collaborators from 24 different Brazilian institutions and one from Colombia among researchers, postdocs, graduate and undergraduate students, and technicians. We processed and analyzed nearly 300,000 specimens from ~60 families of Diptera collected with a large variety of methods in the sampled areas. Here, we provide a detailed overview of the genera and species diversity of 41 families treated. Our results point to a total of 2,130 species and 514 genera compiled and identified for the three states altogether, with an increase of 41% and 29% in the numbers of species and genera known for the three states combined, respectively. Overall, the 10 most species-rich families were Tachinidae, Cecidomyiidae, Tabanidae, Psychodidae, Sarcophagidae, Stratiomyidae, Bombyliidae, Syrphidae, Tephritidae, and Asilidae. The 10 most diverse in the number of genera were Tachinidae, Stratiomyidae, Asilidae, Mycetophilidae, Syrphidae, Tabanidae, Muscidae, Dolichopodidae, Sarcophagidae, and Chloropidae. So far, 111 scientific papers were published regarding taxonomic, phylogenetic, and biogeographical aspects of the studied families, with the description of 101 new species and three new genera. We expect that additional publications will result from this investigation because several specimens are now curated and being researched by specialists.
ABSTRACT
Abstract Here we provide an updated checklist of the odonates from Bodoquena Plateau, Mato Grosso do Sul state, Brazil. We registered 111 species from the region. The families with the highest number of species were Libellulidae (50 species), Coenagrionidae (43 species) and Gomphidae (12 species). 35 species are registered in the IUCN Red List species, four being Data Deficient, 29 of Least Concern and two species being in the threatened category. Phyllogomphoides suspectus Belle, 1994 (Odonata: Gomphidae) was registered for the first time in the state.
Resumo Nós apresentamos um inventário atualizado das espécies de libélulas ocorrentes na Serra da Bodoquena, Estado de Mato Grosso do Sul, Brasil. Nós registramos 111 espécies para a região. As famílias com o maior número de espécies foram Libellulidae (50 espécies), Coenagrionidae (43 espécies) e Gomphidae (12 espécies). 35 espécies são registradas na Lista Vermelha de espécies da IUCN e duas estão em categorias de ameaçadas. Phyllogomphoides suspectus Belle, 1994 (Odonata: Gomphidae) foi registrado pela primeira vez no estado.
ABSTRACT
In this study we have attempted to answer whether there is correspondence between aquatic macroinvertebrate communities and the typological classification of white and clean-water streams in western Amazonia lowlands. We worked within two distinct hydrographic basins: Moa River catchment (clear-water streams) and Azul River catchment (white-water streams) in Serra do Divisor National Park, Acre State, Brazil, sampling 10 streams in each basin. A total of 2,952 individuals were collected, distributed among 134 taxa. Our results show that macroinvertebrate communities, at genus as well as family level, are in concordance to a priori classifications that distinguish between white and clear water streams. The main implication of our results for biomonitoring is that biotic variation between white and clear streams can be partitioned regionally, which would improve the bioassessment accuracy of the Amazonian streams.
Neste trabalho, nós investigamos se há correspondência entre comunidade de macroinvertebrados e classificação de igarapés em águas claras e brancas no oeste da Amazônia. Nós trabalhos em duas bacias hidrográficas, Rio Moa (águas claras) e Rio Azul (águas brancas) no Parque Nacional da Serra do Divisor, Acre, Brasil, amostrando 10 igarapés em cada bacia. Coletamos 2952 indivíduos, distribuídos em 134 taxa. Nossos resultados mostram que a comunidade de macroinvertebrados, identificada com baixa e alta resolução taxonômica, responde claramente a classificação tipológica de igarapés em águas claras e brancas.A principal implicação dos nossos resultados no âmbito de biomonitoramento é que a partição da variação biótica entre igarapés de águas claras e brancas pode melhorar a racionalidade e implantação de sistemas de avaliação ambiental na Amazônia.
ABSTRACT
Larvas de Chironomidae exploram uma grande variedade de habitats e tipos de alimentos. Neste estudo, nós documentamos a ocorrência de larvas vivendo dentro de frutos caídos em córregos de baixa ordem na Mata Atlântica, Brasil. Nós encontramos larvas minando o tecido de frutos de 12 espécies de árvores. Sete morfoespécies de Endotribelos foram identificadas, incluindo as espécies E. albatum and E. grodhaus, encontradas pela primeira vez no Brasil. Os resultados indicam que larvas de Endotribelos constituem o grupo de insetos mais comum em frutos caídos em córregos da Mata Atlântica.
