| Neste trabalho é descrita a variação encontrada na estrutura de fragmentos florestais no Planalto Paulistano, sob diversos aspectos e em diferentes escalas de tamanho. Um censo do componente arbóreo dominante (PAP > ou = 50 cm) em duas áreas (0,5 ha e 0,2 ha) no interior de um fragmento florestal, a Reserva da Cidade Universitária "Armando de Salles Oliveira" (CUASO), Butantã, São Paulo, SP (aproximadamente 23°34'S, 46°43'W) incluiu 227 indivíduos de 50 espécies. Foi encontrada dominância absoluta total (Do) de 20,1 m².ha-1, índice de Shannon (H´) de 3,04 nats.ind-1 e equabilidade de Pielou (J´) de 77,79%. Em cada área, foram encontradas regiões de concentração de espécies pioneiras, secundárias e climácicas. As duas áreas apresentaram diferenças na... |

| The aim of this work was to study the genetic variability among the wild boars, crossbred animals and pigs using microsatellite markers. Five genetic groups were studied. The fragments of three microsatellites developed for Sus scrofa domestica - IGF1, ACTG2 and TNFB - were amplified through PCR technique to evaluate the expected intra populacion variability (He) and observed (Ho) heterozygosity, and endogamy coefficient (F IS ) within each population and inter population variability F IS , testing relationship among five genetic groups to establish the genetic distance among them. The high level of observed heterozygosity values varied between 0.537 and 0.7871. Generally, F IS was low, suggesting that the endogamy did not exist between the tested animals. |

| Background: Improving knowledge of biodiversity will benefit conservation biology, enhance bioremediation studies, and could lead to new medical treatments. However there is no standard approach to estimate and to compare the diversity of different environments, or to study its past, and possibly, future evolution. Presentation of the hypothesis: We argue that there are two conditions for significant progress in the identification and quantification of biodiversity. First, integrative metagenomic studies - aiming at the simultaneous examination (or even better at the integration) of observations about the elements, functions and evolutionary processes captured by the massive sequencing of multiple markers - should be preferred over DNA barcoding projects... |

| A survey of Hymenoptera parasitoids fauna was made in a transect of Eucalyptus/native vegetation/Eucalyptus in Ipaba, state of Minas Minas Gerais, Brazil from March 1997 to March 1998 with Malaise traps. Individuals of nine superfamilies were collected (Ceraphronoidea, Chalcidoidea, Chrysidoidea, Cynipoidea, Evanioidea, Ichneumonoidea, Proctotrupoidea, Platygastroidea and Vespoidea) which belong to 26 families of this order. |
