| In stream environments habitat structure and limnological factors interact regulating patterns of energy and material transfer and affecting fish communities. In the coastal basins of Southeastern Brazil, limnological and structural characteristics differ between clear and blackwaters streams. The former have a diversity of substrate types, higher water velocities, and lower water conductivity, while the latter have sandy substrate, tea-colored and acidic waters, and low water velocities. In this study, we verified the relative importance of habitat structure and limnological variables in predicting patterns of variation in stream fish communities. Eight first to third order streams were sampled in the coastal plain of Itanhaém River basin. We captured 34... |

| Four places in Latin-America have Melipona Illiger, 1806 beekeeping: Mexico, with M. beecheii Bennet, 1831; Northeast Brasil, with M. scutellaris Latreille, 1811; Maranhão State (Brazil) with M. compressipes fasciculata Smith, 1854; Venezuela, in her coast, with M. favosa (Fabricius, 1798). Natural colonies of M. compressipes fasciculata occupied tree holes ranging from 6,5 to 24 1. The average honey production of 60 colonies in hives with capacity of 50.2 1, 41.0, 30.2, 16.5 and 6.2 were respectively 8.4, 6.5, 5.5, 3.3 and 2.0 Kg. Due to lack of bee flowers within the city limits, hives with a volume of 27 1 (30x30x30 cm) were used successfully in our future experiments with M. compressipes fasciculata instead of the ideal size of 40 to 50 liters, since... |

| RESUMO Este trabalho se refere ao pescado desembarcado no Mercado Municipal de Manaus em 1976. A captura total é estimada através de análise de regressão funcional linear. São fornecidas estatísticas de desembarque por mês e por aparelho São mostrados em mapas, acompanhados de suas coordenadas geográficas e da distância de Manaus, os pesqueiros nos diversos rios onde se realiza a pesca. O peixe mais capturado foi o Tambaqui (Coloesoma macropomum) perfazendo 44,1% do total geral em peso (30800 t aproximadamente). O aparelho que mais capturou foi o arrastão (48,6% do total geral). Foram comparados dados do desembarque de dois pesqueiros próximos a Manaus, o lago do Rei (699,2 t) e lago do Janauacá (1277,5 t). |
