| A fauna do solo exerce importante papel nos processos ecológicos do ecossistema. Estudos sobre a composição e estrutura dessas comunidades são importantes para entender o seu funcionamento. Assim o objetivo deste trabalho foi avaliar a comunidade de Coleoptera, coletada mediante armadilhas de solo, quinzenalmente, durante o período de treze meses (08/2003-08/2004), na Mata do Mergulhão, Rio de Janeiro. Foram capturados 10.820 espécimes, representados por 24 famílias, sendo considerados abundantes Nitidulidae (4.782 indivíduos), Curculionidae (3.176 indivíduos), Scarabaeidae (2.019 indivíduos) e Staphylinidae (326 indivíduos), capturadas em todo período de coleta. De acordo com as guildas tróficas, os indivíduos das famílias coletados, podem ser agrupados... |

| The yellow passion fruit, Passiflora edulis f. flavicarpa, is one of the most important Brazilian fruit crops. It is an allogamous, diploid, and self-incompatible species. It has hermaphrodite, solitary flowers, located in the leaf axils and protected by leaf bracts. The flower has an androgynophore, which is a straight stalk supporting its reproductive parts. There are usually five anthers, located at the tip of each of the five filaments. The ovary is borne just above the filaments, at the top of the androgynophore; there are three styles that are united at their base, and at the top there are three stigmas. The objective of this research was to observe embryo sac development in yellow passion flowers. Ovaries at different stages of development were... |

| The yellow passion Passiflora edulis f. flavicarpa Deg. is allogamous, self incompatible, and it depends of insects pollinators to disseminate the pollen grains. The field work was conducted at Campos dos Goytacazes, Rio de Janeiro, Brazil, from October 17 to November 9 and December 12 to 21, 1995. It was analyzed 1565 flower buds, from which 423 showed well developed ovaries, five days after opening, this represents 27% of fruit set by natural pollination. It was observed 76,86 % of completely curved flowers, 21,22 % of partially curved flowers, and 1,92 % flowers without curvature. Five species of bees where observed on the flowers, from which two were the effective pollinator of yellow passion flower: Xylocopa (Megaxylocopa) frontalis (Olivier, 1789)... |
