Trophic niche of Dendropsophus minutus (Anura: Hylidae) in southern Brazil

Trophic niche of Dendropsophus minutus (Anura: Hylidae) in southern Brazil. The feeding biology of the Neotropical tree frog Dendropsophus minutus is described based on identifcation of the items consumed by the anuran. Samples were collected monthly samplings for one year in an Araucaria forest in the state of Paraná in southern Brazil. Of the total of 101 gastrointestines examined, 51 were empty or contained digested remains or plant items. The 50 samples of gastrointestinal contents contained three classes and 10 orders of arthropods. The results suggest that D. minutus is a generalist predator that feeds on arthropods, primarily those in the orders Araneae, Lepidoptera, and Diptera. The diet varies seasonally depending upon prey activity, which determines the breadth of the trophic niche of the frog.Nicho trófco de Dendropsophus minutus (Anura: Hylidae) no sul do Brasil. A biologia alimentar da perereca neotropical Dendropsophus minutus é descrita a partir da identifcação dos itens predados pela espécie. Amostras foram coletadas mensalmente por um ano em uma área de Floresta de Araucária no estado do Paraná, sul do Brasil. Um total de 101 estômagos foi analisado, sendo que desses 51 estavam vazios ou continham itens digeridos ou fragmentos de plantas. As 50 amostras de conteúdo gastrintestinais estudadas continham três classes e 10 ordens de artrópodes. Os resultados sugerem que D. minutus é um predador generalista que se alimenta de artrópodes, principalmente das ordens Araneae, Lepidoptera e Diptera. A dieta varia sazonalmente, dependendo da atividade das presas, o que determina a amplitude do nicho trófco da espécie

Levantamento de histeridae e staphylinidae (Insecta: Coleoptera) em remanescente florestal no Estado do Acre.

A exploração dos ambientes naturais provoca alterações na complexidade e estruturação dos habitats naturais e, acarreta em uma mudança na composição de espécies das comunidades animais anteriormente ali presentes. Dessa maneira se tornam necessários estudos das comunidades de invertebrados em geral, visto o papel fundamental que exercem para o equilíbrio dos sistemas ecológicos. O objetivo desse trabalho foi conhecer a ocorrência e composição de espécies, de coleópteros das famílias Histeridae e Staphylinidae, em remanescente florestal localizado no município de Rio Branco, AC, com utilização de armadilhas pitfall com os atrativos alimentares: banana fermentada, coração bovino em decomposição e fezes humanas

Primeiros registros de Operclipygus marseul (Coleoptera: Histeridae) para o Estado do Acre e para o Brasil.

Os Histeridae são um grupo de besouros com hábito predatório generalista, os quais possuem importantes funções ecológicas como participação no ciclo de decomposição da matéria orgânica, utilização no controle biológico e na entomologia forense. O estudo foi conduzido de março a agosto de 2016, em um remanescente florestal situado no campo experimental da Embrapa Acre, Rio Branco, AC. Foram instaladas nove armadilhas do tipo ?pitfall trap?, com utilização de três atrativos alimentares (fezes humanas, coração bovino em decomposição e banana fermentada), dispostos em um triângulo equilátero com 15 metros de lado. Eram realizadas duas coletas semanais (segundas e sextas-feiras), substituindo-se as armadilhas, bem como os atrativos. O material foi triado no Laboratório de Entomologia da Embrapa Acre, sendo os Histeridae preservados em álcool 70% e enviados para a identificação taxonômica ao menor nível possível. Neste trabalho são apresentadas as espécies Operclipygus kerga e Operclipygus florifaunensis como primeiros registros para o estado do Acre e Operclipygus lama como primeiro registro para o Brasil.Editores técnicos: Virgínia de Souza Álvares; Fabiano Marçal Estanislau

Distribution. Dominican Republic. Etymology. This species is named after a great Histeridae researcher, Dr. Peter Kovarik, who loaned this interesting material to the corresponding author. Remarks. When compared to Omalodes angelo sp. nov., this species has weaker punctures on the lateral margin of pronotum, a broader prosternum (mainly prosternal keel and process), punctures more sparse on the propygidium and a large glandular opening on each side, posterad to metacoxae. This species along with O. angelo sp. nov., O. haitianus and O. ruficlavis share a unique character (complete apical stria) and a sympatric distribution, limited to a portion of the Caribbean region (Haiti, Dominican Republic, and Cuba). Punctures on the pygidium are variable in O. kovariki sp. nov., most specimens possess stronger punctures on the anterior angles, weaker medially and absent posteriorly, but in a few specimens the medial punctures are slightly stronger.Published as part of Moura, Daniel P., Leivas, Fernando W.
