2. DIETA, DINÂMICA POPULACIONAL E ECTOPARASITAS DE PHRYNOPS GEOFFROANUS (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) DO BAIXO SÃO FRANCISCO, POÇO REDONDO, SE. / DIET, AND POPULATION DYNAMICS OF PHRYNOPS GEOFFROANUS ECTOPARASITES (SCHWEIGGER, 1812) (TESTUDINATA, CHELIDAE) THE LOWER SAN FRANCISCO, POÇO REDONDO, SE.
Population of P. geoffroanus of Unidade Unidade de Conservação Estadual Monumento Natural Grota do Angico (MNGA) (3740W; 0939S) was studied in relation of their diet, morphometry, growth rates and mass gain, structure and dynamic population and parasites (leeches). The sampling of specimens was performed in monthly campaigns over a year (between January an

3. Community structure of metazoan parasites of silverside, Odontesthes bonariensis (Pisces, Atherinopsidae) from Argentina
The helminth communities of silverside, Odontesthes bonariensis (Valenciennes, 1835), from two Argentinean lagoons were studied and compared at component community and infracommunity levels. Nine helminth species were found: five digeneans (Austrodiplostomum cf. mordax, Ascocotyle (Phagicola) cf. diminuta, Ascocotyle sp., Thometrema bonariensis and Saccocoel

4. Change in the meiofauna community structure of sandy beaches of the Nuevo Gulf (Chubut, Argentina)
The composition and distribution of the benthic meiofauna assemblages of the Nuevo Gulf (Chubut, Argentina) are described in relation to abiotic variables. The meiofauna and sediment samples were collected in the intertidal zone of four sandy beaches with different anthropic disturbances in June 2005. The samples were obtained at 20 sampling sites using a 2.

5. Structural and functional analysis of VT1 and YP170B vitellins from the Rhabditid nematodes Oscheius tipulae and Caenorhabditis elegans. / Estudo das vitelinas VT1 e YP170B dos nematoides rabditídeos Oscheius tipulae e Caenorhabditis elegans: aspectos estruturais e funcionais.
The N-terminal region of OTI-VIT-1 was expressed and the recombinant polypeptides were purified. OTI-VIT-1 may be homologous to the vitellin YP170B from C. elegans. We identified an intron in the 5 region and two in 3region from Oti-vit-1. Monospecific antisera to PVIT1HisC confirmed that the gene Oti-vit-1 encodes VT1. The recombinant polypeptide P40-H, cor

6. Determinação de motivos de ligação à quitina em vicilinas de Canavalia ensiformis e Vigna unguiculata através de métodos in silico e relação com suas toxicidades para o bruquídeo Callosobruchus maculatus (Coleoptera:Bruchidae)
Chitin is an important structural component of the cellular wall of fungi and exoskeleton of many invertebrate plagues, such as insects and nematodes. In digestory systems of insects it forms a named matrix of peritrophic membrane. One of the most studied interaction models protein-carbohydrate is the model that involves chitin-binding proteins. Among the in

7. Comunidade,dinâmica populacional e variabilidade espacial de nematóide em áreas de cultivo da cana-de-açúcar sob diferentes condições edafoclimáticas no Nordeste
Community trophic structure and spatial distribution of nematodes, in particular Meloidogyne spp. and Pratylenchus zeae, in soil at field renovation and harvest of sugarcane (Saccharum spp.) are fundamentals for understanding shifts in population dynamic and consequent effects on crop production. The objectives of the present study were 1) to characterize pl

8. Species assembly rules and the biodiversity-ecosystem functioning relationship / Regras entre assemblÃias de espÃcies: relaÃÃo entre biodiversidade e funcionamento do ecossistema
The biological diversity of ecosystems has important implications for their functioning. However, in order for reliable predictions to be made on the effects of species extinctions and/or additions on particular ecosystem functions, accurate knowledge is required on the ways in which species interact. These interactions in turn are important drivers of commu

9. A meiofauna e os Nematoda da enseada Martel (Antártica) e seu uso em monitoramento ambiental / Meiofauna and nematodes from Martel inlet (Antarctica) and their use in environmental monitoring
The aim of this study was to verify if meiofauna, Nematoda family and genera community structure show modification caused by human activities at the Brazilian Antarctic Station (CF), in relation to a reference area (BP). Mean meiofauna densities ( ind.10 cm-²) ranged from 7028 (? 1529) to 16245 (? 12282) at 20-30 m and from 1569 (? 928) and 7088 (? 10338) a

10. Helmintofauna de Columba livia (Aves, Columbidae), no município de Juiz de Fora, Minas Gerais, Brasil: aspectos da ecologia, morfologia e sistemática
The aim of the present study was to obtain data on helminth fauna in Columba livia, in municipality of Juiz de Fora, Minas Gerais, Brasil; to describe the structure of the helminth infracommunities present in this host and to clarify questions concerning morphology, sistematics and ecology of some of the component species. The helminthological study of 35 ho

11. Structure and dynamics of the macrobenthic communities of Ubatuba Bay, southeastern Brazilian Coast
A composição, distribuição, densidade, biomassa, diversidade e relações tróficas das comunidades macrobênticas da Enseada de Ubatuba, costa sudeste brasileira, foram estudadas sazonalmente, de agosto de 1995 a junho de 1996. As amostragens foram realizadas em 9 estações de coleta, situadas entre 4 e 13 m de profundidade, e obtidas em duplicata com

12. Composition and structure of the parasite community of Bufo ictericus (Spix, 1824) (Anura: Bufonidae) from Municipality of Miguel Pereira, State of Rio de Janeiro, Brazil / Composição e estrutura da comunidade parasitária de Bufo ictericus (Spix, 1824) (Anura: Bufonidae) do Município de Miguel Pereira, Estado do Rio de Janeiro, Brasil
Thirty-two specimes of Bufo ictericus (Spix, 1824), 22 males and 10 females, collected in the Municipality of Miguel Pereira, State of Rio de Janeiro, Brazil, from April 2003 to August 2003, were necropsied to study their metazoan parasites. Thirty-one (97%) specimens of B. ictericus were parasited by one or more metazoan species. Sixteen species of parasite
