| O Parque Nacional dos Aparados da Serra (PNAS), localizado na borda oriental do Planalto das Araucárias, é uma das principais unidades de conservação do sul do Brasil, caracterizando-se pela ocorrência de fragmentos de floresta ombrófila mista, intermediada por campos secos e úmidos, e por uma área contínua de floresta ombrófila densa. Registraram-se, para o PNAS, 35 espécies de planárias terrestres, distribuídas em cinco gêneros (Geoplana Stimpson, 1857, Choeradoplana Graff, 1896, Notogynaphallia Ogren & Kawakatsu, 1990, Pasipha Ogren & Kawakatsu, 1990 e Cephaloflexa Carbayo & Leal-Zanchet, 2003), pertencentes à família Geoplanidae, subfamília Geoplaninae. Observaram-se 23 e 21 espécies, respectivamente, nas áreas de floresta... |

| Land flatworms are carnivorous, mainly predators. However, knowledge on their predatory behavior and prey preference is very scarce. This paucity of data is a limiting factor in the study of their biology and organismal ecology, resulting in a very difficult task to breed them in the laboratory for prolonged periods if prey preference and predation frequency are unknown. We investigated the predatory behavior of Notogynaphallia abundans (Graff, 1899), Geoplaninae, based on laboratory experiments. In order to determine its predatory choices, we offered mollusks, earthworms, arthropods, and other land flatworms. Only land isopods were accepted, with an average consumption of 3.4 individuals per week. Linear regression showed a positive relationship between... |

| Glands of the reproductive system are important for taxonomical identification of flatworms. We studied the histology and histochemical characteristics of the glands of the male copulatory apparatus in Girardia anderlani (KAWAKATSU & HAUSER, 1983). Specimens were fixed in reproductive state, i. e. during and following copulation at four, eight, 12 and 16 hours intervals. Secretory cells were distinguished on the basis of secretion morphology and their staining properties, using trichrome methods and histochemical reactions. Twelve secretory cell types and five main types of secretions were identified in the male copulatory apparatus: glycoproteic with and without tryptophan; glycosaminoglycidic; neutral mucopolysaccharidic; and proteic. Compared to... |
