The diet of tadpoles 13 anuran species was determined to verify whether food resource partitioning occurs and the degree similarity is related taxonomic affinity. Tadpoles all studied were mainly herbivorous, except for these Leptodactylus fuscus (Schneider, 1799) which mycophagous. Although some had exclusive items in their diet, most tadpole ingested same items, but differed amount each item consumed. Two guilds found: that feed on diatoms pond bottom, Oedogonium Link, 1820 algae midwater....
We determined microhabitat and diet niche for tadpoles from two ponds in an agricultural landscape. Additionally, we verified the intraspecific variation resource use, if use were correlated. Tadpoles found differed because larger pond they explored deeper places far margin. There three groups with high overlap. In both ponds, plant cover was best descriptor to explain interspecific use. of all species ingested mainly Bacillariophyceae Trachellomonas however intraspecifically ponds. Ten...
The presence of adult specimens and eggs Temnocephala pignalberiae Dioni, 1967 in Dilocarcinus pagei Stimpson, 1861, at Poconé, Brazilian ‘Pantanal’, State Mato Grosso, together with abundant material also collected from D. Bebedouro, São Paulo, are reported. These two records allowed the extension known geographical distribution T. Argentina to Central Brazil, comparison temnocephalan infrapopulations allopatric crab populations, living approximately 1,300 km apart each other. entire sample...
The geographic distribution of Sphaenorhynchus lacteus comprises Amazon and Orinoco basins South America, Guianas, eastern Brazil Trinidad. Herein, we report for the first time occurrence genus state Piauí.
Rhinella jimi toads (Stevaux, 2002) belong to the Bufonidae family, are endemic in Brazilian Northeast and commonly found during rainy periods. In general, amphibians of this family have their poisons different metabolites that show a diversity pharmacological activities. The isolation identification these compounds great importance, techniques such as high-performance liquid chromatography coupled mass spectrometry widely used for discovery novel known poisons. For R. poison, ethyl acetate...
The chytrid fungus Batrachochytrium dendrobatidis (Bd) has been linked to the declines of more than 500 amphibian species globally. In Brazil, Bd identified in several regions but predominantly Atlantic Forest. Data on occurrence this pathogen northeastern Brazil are scarce, specifically from Caatinga ecoregion, where there is only one study that reports region. This first show a high prevalence Caatinga’s and includes two new records infected by Bd: Rhinella granulosa R. jimi. addition, we...
The genus Physalaemus is widely distributed over South America, east of Andes. cicada belongs to the cuvieri group, Caatinga and usually found in lentic and/or temporary water bodies. Herein, we extend its geographical distribution providing first record for Piauí state, municipality Picos.
Apresentamos dados sobre uma comunidade de anuros e seus padrões distribuição em área ecotonal no nordeste do Brasil. As coletas foram realizadas semestralmente julho 2007 a 2012 município Barras, por meio busca ativa visual auditiva poças d’água permanentes temporárias. Foram registradas 27 espécies anuros, pertencentes 13 gêneros cinco famílias. Hylidae foi família com o maior número (44%, n = 12 spp.), seguida pela Leptodactylidae (37%, 10 spp.). Apesar 40% das serem ampla geográfica,...
Apresentamos um inventario das especies de repteis uma regiao ecotono no estado do Piaui, nordeste Brasil. Realizamos as coletas semestralmente periodo 2007 a 2011 por meio busca ativa em diferentes fitofisionomias. Registramos 25 repteis, sendo 22 Squamata (11 cobras, 10 lagartos e amphisbaena), dois Testudines Crocodiliano. Embora maioria dos amostrados seja ampla distribuicao geografica, 20% (n = 5) registradas sao tipicas formacoes florestais, apresentam ocorrencia principalmente bioma...
Este estudio tuvo como objetivo analizar un caso de alto nivel infección con acantocéfalos para comprender si el patrón está relacionado las características biológicas los hospederos. Se recolectaron 33 ejemplares Rhinella marina (Linnaeus, 1758) Huanuco, Perú, y luego se utilizó la prueba rango Spearmans (r ) calcular posibles correlaciones entre tamaños del cuerpo hospedero abundancia parásitos, tamaño parásito parásitos. Los helmintos fueron identificados Pseudoacanthocephalus lutzi...

Cases of poisoning have increased considerably in Brazil, however for state Piauí only two studies were carried out so far. Here, we investigated, through the notification forms, epidemiological characteristics cases that occurred during 11 years a macro-region Picos, Piauí, Northeastern Brazil. Furthermore, also check whether species recorded forms correspond to occur region. We 1.249 envenomations, being 41% caused by scorpions, 35% snakes and 24% spiders. Most (arachnids = 99%, scorpions...
The objective of this study was to detect the presence local edema and hemorrhage caused by Crotalus durissus terrificus envenoming using magnetic resonance imaging (MRI). Six patients bitten snakes were treated at Emergency Unit Tropical Diseases Botucatu School Medicine, UNESP, São Paulo State, Brazil. After receiving specific serotherapy, submitted MR bite site. Post contrast T1 T2 spin-echo MRI obtained revealing following lesions: associated with in subcutaneous muscular tissue (n=3),...
