Abstract Freshwater assessment studies have been used changes on individuals and populations of Chironomidae assemblages as bioindicators to assay aquatic ecosystems environmental quality. To assess the contribution with this family response changes, we carried out a scientometric analysis papers published from 1992 2012. We imported ISI Web Knowledge database (Thomson Reuters) in November 2013. A total 2967 were evaluated descriptive main trends research freshwater assessments. The ideas...
The degradation of subterranean habitats is believed to represent a serious threat for the conservation obligate dwellers (troglobites), many which are short-range endemics. However, while factors influencing cave biodiversity remain largely unknown, influence surrounding landscape and patterns connectivity terrestrial troglobitic communities have never been systematically assessed. Using spatial statistics analyze most comprehensive speleological database yet available tropical caves, we...
Systematics and distribution of freshwater sponges is still poorly understood worldwide. This may be due to the scarcity records, limited information about morphological traits used for taxonomy. Brazil has reportedly high species richness in Neotropical Region; however, this diversity likely significantly underestimated given that there are many unexplored sampled areas, mainly north northeast regions. We present here new locality records taxonomic notes on three families ten Porifera from...
Radiospongilla Penney & Racek, 1968, characterized by gemmoscleres radially arranged on gemmules and absence of microscleres, is widely distributed in the world across all zoogeographical regions except for Antarctica. In Neotropical Region only two species are known so far: R. crateriformis (Potts, 1882) amazonensis Volkmer-Ribeiro Maciel, 1983. Here we describe a new Radiospongilla, inesi sp. nov., from 28 specimens collected between May 2007 to April 2010 channels ponds at Aquaculture...
The confusion about the genus Tubella began when Carter (1881) relocated three species described by Bowerbank (1863)—Spongilla paulula; Spongilla reticulata and recurvata to Tubella, also spinata. However, ignored Gray (1867) who proposed Metania for S. paulula, Acalle recurvata. Later, Vejdovsky (1888) Trochospongilla comprising which have only one type of megasclere, without microscleres birotulate gemmoscleres with rotules that may unequal size. These features were congruent some Tubella....
AbstractThis paper expands the known geographic distribution of Corvospongilla seckti Bonetto and Ezcurra de Drago, 1966 to another two Brazilian hydrographic basins, East Atlantic São Francisco basins. Simultaneously, it reassesses status C. volkmeri De Rosa Barbosa, 1988. Re-examination holotype revealed no remarkable diagnostic features differentiate from seckti, given our present knowledge on variability latter. Accordingly, is considered a junior synonym seckti.Keywords: basinfreshwater...
A região Neotropical possui uma rica fauna de esponjas água doce, porém o conhecimento sobre sua taxonomia, bem como as comunidades dentro delas permanece fragmentado. Larvas Chironomidae (Insecta, Diptera) associadas a doce têm sido amplamente relatadas na literatura, com alguns gêneros que são reconhecidos contendo espécies exclusivamente dependentes desses organismos. Neste estudo, analisamos ocorrência larvas (Spongillidae) no nordeste do Brasil. As amostras foram coletadas em dois...
A carcinicultura nos manguezais promovem conflitos socioambientais entre empresários da indústria do camarão e as comunidades tradicionais pelo direito ao uso acesso dos recursos naturais nesses ecossistemas. Este estudo analisou os cenários dessa atividade econômica mediante revisão bibliográfica das problemáticas relacionadas à no Nordeste Brasil. Em geral, a ineficiência legislação ambiental para gestão de conflitos, falta uma justa participativa representatividade na solução desses...
The demosponge genus Crelloxea Hechtel, 1983 was created to allocate a single species, spinosa 1983, described based on specimens collected by Jacques Laborel in northeastern Brazil 1964 and deposited at the Porifera Collection of Yale Peabody Museum. originally defined as "Crellidae with dermal interstitial acanthoxeas acanthostrongyles, skeletal oxea without microscleres or echinators" (Hechtel, 1983). allocated marine sponge family Crellidae (Order Poecilosclerida), which is characterized...
Abstract We investigated how components of beta diversity (i.e., the turnover and nestedness functional compositional) aquatic insect assemblages change among sites are influenced by environmental spatial drivers. For this, we analyzed beta-diversity composition Ephemeroptera, Plecoptera, Trichoptera in 16 streams two Amazonian basins with distinct conditions (the Carajás Tapajós regions). performed Multiple regression on dissimilarity matrices (MRM) Procrustes analysis to test influences...
