A second inseminating species bearing club cells organized into an anal-fin gland in sexually active males belonging to the genus Bryconadenos was recently discovered in the rio Xingu drainage and is described as new. It is distinguished from B. tanaothoros by the presence of a conspicuous dark blotch at the humeral region, and fewer scale rows between dorsal-fin origin and anal-fin origin. Males of B. weitzmani have longer pelvic fins at sizes beyond 30 mm SL. Bryconadenos weitzmani is further distinguished from B. tanaothoros by the cup shape of the anal-fin gland, its lower part much more developed than the upper, whereas in B. tanaothoros there is just a slit separating the almost equally developed upper and lower parts.

ABSTRACT A new species of Poptella is described from the Rio Juma, a tributary of the lower Rio Aripuanã, Rio Madeira basin, Amazonas, Brazil. The new species is distinguished from all congeners, except P. brevispina, by having a lower number of scale rows between the lateral line and dorsal-fin origin (7 vs. 8-10). The new species can be readily distinguished from P. brevispina by the lower number of branched dorsal-fin rays (9 vs. 10). This is the first description of a new species of Poptella since the revisionary study of the Stethaprioninae, published 30 years ago.

MOURA, M. A. M.; JONSSON, C. M..

Abstract: Sugarcane cultivation is the most important agricultural activity in the State of São Paulo, which is responsible for over half of Brazilian production of the crop. Eutrophication and contamination of hydric resources caused by agricultural chemicals are major problems related to this crop. In the case of herbicides used to control weeds, aquatic organisms can be exposed to more than one toxic agent, and combinations of such pollutants can have different effects on biological systems. The aim of this work was to evaluate the toxic effects of mixtures of herbicides widely used in sugarcane cultivation, namely tebuthiuron (TBUT), ametryn (AMT), and Velpar K (a commercial mixture of diuron (DIU) and hexazinone (HZN)), to tilapia (Oreochromis...

Resumo: A cana-de-açúcar é o carro-chefe da agricultura paulista e o Brasil é líder mundial na produção do etanol em larga escala, um combustível renovável que contribui para a redução da emissão de gases de efeito estufa, por evitar a queima de combustíveis fósseis. A alta produtividade desta cultura necessita, entretanto, do uso intensivo de defensivos agrícolas, que podem contaminar mananciais próximos às áreas de cultivo ou mesmo serem transportados afetando ecossistemas distantes. O uso simultâneo de diferentes herbicidas é comum nas lavouras, mas sua interação e o impacto sobre espécies não-alvo não são bem conhecidos. O objetivo deste trabalho foi avaliar o efeito da mistura de herbicidas ametrina e diuron, usada na lavoura canavieira, sobre o...
