| Clinodiplosis Kieffer, 1895 (Diptera, Cecidomyiidae) é gênero cosmopolita conhecido por 103 espécies, a maioria micófaga. Com base na literatura e dados da coleção de Cecidomyiidae do Museu Nacional, Rio de Janeiro, a diversidade deste gênero no Brasil é avaliada, e informações sobre as espécies, seus hábitos e galhas são apresentadas. O gênero está representado, no Brasil, por 57 espécies (17 descritas e 40 não determinadas), o que corresponde a cerca de 16% do total de espécies descritas e 74% da fauna Neotropical. A maioria das espécies encontradas no Brasil é indutora de galhas (81%) e, destas, a metade induz galhas foliares. Gema, flor e caule foram outros órgãos vegetais galhados. As espécies estão associadas a trinta famílias botânicas, sendo mais... |

| Gall-inducing insects of an Araucaria Forest in southern Brazil. Diversity of galling insects is reported for the first time in an Araucaria Forest site. We address gall characteristics, host plant identification and the inducer identification and provide additional information about sites of gall occurrence in a mosaic of continuous forest and natural forest patches. After 40h of sampling we found 57 species of five insect orders, the majority of them Diptera (Cecidomyiidae), galling 43 host plant species, which in turn belonged to 18 host plant families. Stem and buds together, compared to leaves, harbored more galls, which were mostly glabrous, isolated, fusiform and green. Myrtaceae, Asteraceae and Melastomataceae were the most representative host... |

| Anti-predator mechanisms in snakes are diverse and complex, including mimetic behavior. Some snakes triangulate their head, probably mimicking other more dangerous snakes. However, there is a lack of studies that demonstrate the effectiveness of this behavior with natural predators. The aim of this study was to verify, using artificial snakes, if snakes with triangular heads are less susceptible to attack by predators, and if predatory attack is targeted to the head of serpents. Artificial snakes were systematically arranged on a road border. The rate of attacked models was 48.71%. Number of attacks on models with rounded head was significantly higher than in models with triangular head. There was a significant difference between the places of attack on... |
