In this work, categorizes the territory from the relational point of view of power and space usage, referring to the management of multiple use of natural resources Conservation Unit National Forest Jamanxim.Created by presidential decree of February 2006 has an area of 1.3 million hectares in the municipality of Novo Progresso, near the BR-163, have recently been the scene of battle in which it is being claimed their (re) territorial configuration.On one hand some local staff with the support of politicians from the region, aims to stay occupying 46% of the total area, land contours by forming a mosaic of conservation units in the area that today is the National Forest.Across the Chico Mendes Institute for Biodiversity Conservation - ICMBio defending the permanence of the whole area as a National Forest, excluding, however, three of the 13 regions studied and evaluated by analysts of the institute in 2009.This study aims to analyze the proposed redefinition of territorial NF, specifically the feasibility of implementing the same in each of the proposals for both the work utilizes the tool of remote sensing in order to perform multitemporal mapping of the dynamics of use and occupancy Soil in National Forest Jamanxim, aiming to investigate the dynamics of occupation used in the area, showing the convention anthropism Forest in the years 1984, 1990, 2000 and 2009.The result shows that FLONA the Jamanxim has its history of occupation similar to the rest of the Amazon region, encouraged by colonization programs offered by the Federal Government, the population that resides inside back the 70 and 80, which begin to use the land in order to deploy to deforest livestock, mining, logging and so on.The form of territorial occupation of the area that today is the National Forest Jamanxim indicates that the battle for territorial redefinition or other categories of conservation areas will be less restrictive distant, while there are barriers on the part of the managing agency (ICMBio) to perform the full management FLONAthe Jamanxim.

Inventário de aranhas (Arachnida, Araneae) em quatro fitofisionomias da serra do cachimbo, Novo Progresso, Pará, Brasil

A inventory of the spider fauna was carried out at Serra do Cachimbo, inside the "Campo de Provas Brigadeiro Velloso", Novo Progresso municipality, Pará state, Brasil. Two expeditions were made, during both dry (August and September, 2003) and wet (March and April, 2004) seasons. Three collectors participated in each expedition. The sampling effort, represented by 240 samples, was divided through the following methods: beating tray and sweeping net (96 samples); nocturnal hand search (96 samples) and concentrated litter sorted by a combination of hand search and Winkler extractors (48 samples). The spiders assemblages from four vegetation types (open rainforest, Formiga river's riparian forest, arboreal savanna and white sand vegetation) were compared. A total of 4964 spiders were obtained, from which 2724 adults, resulting in 397 recognized morpho-species in 37 families. The most abundant families were Theridiidae, Salticidae and Araneidae and the ones with more species were Salticidae, Araneidae e Theridiidae. The singletons represented 40% of the total species richness and only two species presented more than 100 individuals. The estimated richness species curves reached from 473 (bootstrap) to 674 (jackknife2) species. The higher alpha-diversity (Shannon-Wiener index) was observed in open rainforest, followed by Formiga river's riparian forest, white sand vegetation and arboreal savanna. the higher beta-diversity (Jaccard and Morisita-Horn indexes) was observed between Open rainforest and white sand vegetation and the lowest one was between open rainforest, arboreal savanna and Formiga river's riparian forest. The dry season presented more species than the wet season. However, no such difference was detected in white sand vegetation. A principal component analysis revealed that some species are linked to arboreal vegetations and others are linked to the open vegetation in white sand. Those differences in diversity and taxonomic composition between the various vegetations can be explained by drifts in availability of food items (preys), space resources (refugees and substratum to web attachment), as well as micro-climatic factors (temperature and moisture) of a given vegetation type. The most experienced conectar sampled more species than any other collector and all less experienced collectors sampled similar number of species. The differences in abundance among samples obtained by each conectar were not significant. The night hand sampling was the most efficient technique regarding the detection of differences in species richness among vegetation types. The methods beating tray/sweep net and litter sampling do not showed any significant difference in relation to species richness.
