Estrutura da comunidade de macroinvertebrados aquáticos de um riacho de Mata At...
Azevedo, Rafael Santos de; Dumas, Leandro; Rodrigues, Daniela; Rezende, Carla Ferreira; Caramaschi, Érica Pellegrini; Mazzoni, Rosana; Nessimian, JorgeComposition, diversity and density of benthic macroinvertebrates were described based on samples from the four different sites of Rio Mato Grosso, Saquarema, Rio de Janeiro. Biotic and environmental data were obtained in January 2006 in microhabitats with different substrates. A total of 5.605 specimens of the 28 insect families and two crustaceous families are sampled. The lowest values of richness, diversity,...
Small forest losses degrade stream macroinvertebrate assemblages in the eastern...
Brito, Janaina G.; Roque, Fabio O.; Martins, Renato Tavares; Nessimian, Jorge; Oliveira, Vívian Campos de; Hughes, Robert MasonGenerally, habitat loss and fragmentation negatively affect biota, often in nonlinear ways. Such nonlinear responses suggest the existence of critical limits for habitat loss beyond which taxa experience substantial changes. Therefore, we identified change points for aquatic macroinvertebrate assemblages at both local-riparian and catchment extents in response to a forest-loss gradient in agriculture-altered la...
A new species of Buenoa Kirkaldy (Hemiptera, Heteroptera, Notonectidae) from Ri...
Barbosa, Julianna Freires; José, Ricardo Inacio Ribeiro; Nessimian, JorgeMembers of Buenoa are restricted to the Western Hemisphere, with the greatest diversity of species in South America. There are about 50 described species and approximately 20 of them have been reported from Brazil. Buenoa pseudomutabilis Barbosa, Ribeiro and Nessimian, sp. nov. is described here from Maricá, Rio de Janeiro State. This species resembles B. mutabilis Truxal, 1953 because males have a stridulatory...
Identification key to families and genera of larvae of Trichoptera from Central...
Pes, A. M.; Hamada, Neusa; Nessimian, JorgeKeys for identification of larvae to families and genera of Trichoptera of Central Amazonia are presented.
A social and ecological assessment of tropical land uses at multiple scales: Th...
Gardner, Toby Alan; Ferreira, Joice Nunes; Barlow, Jos; Lees, Alexander C.; Parry, Luke; Guimarães Vieira, Ima Cèlia; Berenguer, ErikaScience has a critical role to play in guiding more sustainable development trajectories. Here, we present the Sustainable Amazon Network (Rede Amazônia Sustentável, RAS): a multidisciplinary research initiative involving more than 30 partner organizations working to assess both social and ecological dimensions of land-use sustainability in eastern Brazilian Amazonia. The research approach adopted by RAS offers...
Insecta, Coleoptera, Elmidae, Amazon region
dos Passos, Maria Inês Silva; Fernandes, André Silva; Hamada, Neusa; Nessimian, JorgeA list of Elmidae species from Amazon is presented. The list was prepared based on a literature survey and examination of the entomological collection of Instituto Nacional de Pesquisas da Amazônia (INPA). The list includes 102 species, with ten new occurrences recorded, being one for the Amazon (which includes areas of Brazil, Bolivia, Colombia, Guyana, French Guyana, Peru, Suriname and Venezuela) three for th...
