Última Variation and life strategies of the Trichoptera (Insecta) larvae community in a first order tributary of the Paquequer River, Southeastern Brazil BJB HUAMANTINCO,A. A.; NESSIMIAN,J. L.. The Trichoptera fauna was sampled in a first order tributary of Paquequer River, in the district of Teresópolis, Rio de Janeiro State. Quantitative samples of litter from pools, litter from riffles, sand, and stones were taken on each season from February 1991 to February 1992.The life cycles of common genera were categorized into three groups of biological strategies. The largest group represented the general profile of the community, in which ultimate instar larvae were predominant in spring and the younger ones in summer. Probably, emergence and oviposition occur in spring. Tipo: Info:eu-repo/semantics/article Palavras-chave: Trichoptera; Larvae; Life strategies; Streams; Atlantic Forest.

F.; BUSS,D. F.; DORVILLÉ,L. F. M.; NESSIMIAN,J. L.. Diversity and habitat preference of macroinvertebrates were studied in Macaé River basin, Rio de Janeiro State, Brazil, along its longitudinal gradient. We selected stream reaches corresponding to 1st, 2nd, 4th, 5th and 6th orders. A Surber sampler was used to collect four macroinvertebrates samples of each substrate (sand, litter in pool areas, stones, and litter in riffle areas) during the three sampling periods, defined based on the rain regime: April (end of the rainy season), July (dry season), and October (beginning of the rainy season). We identified 46,431 specimens corresponding to 117 taxa. Analysis of diversity numbers (both for family or genus level) indicated that all insect taxonomic orders had higher numbers on 2nd order stream reach, except...
