Poecilancistrium caryophyllum (Diesing, 1850) (Cestoda, Trypanorhyncha), parasito de Macrodon ancylodon (Bloch Ĵ Schneider, 1801) do litoral Norte do Brasil

Macrodon atricauda (Günther, 1880) (Perciformes: Sciaenidae), a valid species from the southwestern Atlantic, with comments on its conservation

The American sciaenid genus Macrodon presently consists of only two species, the Atlantic Macrodon ancylodon (Bloch & Schneider, 1801), and the Pacific Macrodon mordax (Gilbert & Starks, 1904). The two species are distinguished mainly by the number of pored scales on the lateral line (66–78 in M. ancylodon vs. 45–55 in M. mordax). The present study revalidates a third species, the second from t...

Characterization of Enzymatic profiles of Aedes aegypti strains from the State of Rio Grande do Norte, Brazil Caracterização de perfis enzimáticos de cepas do Aedes aegypti do Estado do Rio Grande do Norte, Brasil

Molecular phylogeny and evolution of the Trypanorhyncha Diesing, 1863 (Platyhelminthes: Cestoda).

Complete ssrDNA and partial lsrDNA (D1-D3) of 31 species, mainly from the Indo-Pacific region, were sequenced and added to 66 species of the marine cestode order Trypanorhyncha; thus 35% of the 277 known species were sampled. The resulting phylogenetic tree resolved two major clades that represent trypanorhynchs originally parasitizing rajiform (skate and ray) or galeoform hosts. The tree topol...

Associações entre as biomassas de peixes Sciaenidae (Teleostei: Perciformes) e de camarões Penaeoidea (Decapoda: Dendrobranchiata) no litoral norte do Estado de São Paulo

To study the relationships among Sciaenidae fish and Penaeoidea shrimp biomass, fieldwork was carried out in the north coast of São Paulo state, Brazil, during the four seasons of 2001. Samples were collected in transects from different depths at Ubatuba, Caraguatatuba, and São Sebastião cities. Water and sediment were collected from each transect. The hypotheses that the environmental factors ...
