1. Apedilum griseistriatum comb. nov., placement of Chironomus (Polypedilum) griseistriatum (Diptera, Chironomidae)
The study of the type material of Chironomus (Polypedilum) griseistriatum Edwards, 1931 described from Patagonia lead us to formally transfer the species to Apedilum Townes, 1945 as a new combination, and a reared specimen allows us to describe its pupa. Based on several larvae belonging to Apedilum collected in the proximity of the localities in which the a

2. Determination of larval instars in Chironomus sancticaroli (Diptera: Chironomidae) using novel head capsule structures
Determining the age composition of a population is important when conducting ecological, taxonomic and environmental assessments. Morphometric measurements of the head capsule, especially the length and width, are widely used in the identification of insect instars, but alternative ways for determining the age of insects can expand the options for the analys

3. Alimentação de Potamotrygon signata e Potamotrygon orbignyi (Chondrichthyes: potamotrygonidae) na bacia do rio Parnaíba.
The evaluation of this diet, based on stomach content analisys, has already became rutine practice in fish ecology studies. The family Potamotrygonidae, represented by all Neotropical fresh water sting rays, is considered the only eslamobranch family whose members are totally restricted and adapted to this enviroment. The samples were obtained in the months

4. Dinâmica de macroinvertebrados em um lago costeiro do sul do Brasil(Lagoa da Reserva, Mostardas-RS)
In view of its great biological diversity and productivity, in addition to its many functions and values, the wetlands ecosystems are priority for conservation. The lack of information about biodiversity is the main limitation for their conservation. Moreover, the identification of the environmental factors responsible for the structure of biological communi

5. Effects of taxonomic resolution of benthic invertebrates in the assessment of lotic ecosystem s quality / Efeitos da resolução taxonômica de invertebrados bentônicos no diagnóstico da qualidade de ecossistemas lóticos
Nas últimas décadas, tem-se observado uma expressiva queda da qualidade ambiental e perda de biodiversidade nos ecossistemas aquáticos em função de múltiplos impactos advindos de atividades antrópicas. Dessa forma, considerando-se que a estrutura das comunidades pode ser alterada por tais perturbações, diversos métodos têm sido propostos para aval
