1. Drought resistance in seedlings tree species of semideciduous tropical forest / Resistência à seca em plântulas de espécies arbóreas da floresta estacional semidecídua
The rainfall is high in tropical forests, but there is great variation in water availability to plants. On a local scale, this availability may vary depending on the location of individuals in gaps, their position in the landscape and soil composition. On a regional scale, variations related to the volume and distribution of rainfall, coupled with seasonal c

4. Aspectos da estrutura fitossociológica e silvigenética em fragmentos de floresta estacional semidecídua com diferentes histórias de perturbação em Botucatu, SP / Aspects of the phytossociological and silvigenetic structure of seasonal semi deciduous forest fragments with different disturbance histories, at Botucatu, SP
The seasonal semi deciduous forest fragments in São Paulo State suffered the fragmentation process mainly because agricultural and urban expansion. These remnants are very important for taxonomic and ecological studies, although they are much altered. By joining phytossociological and silvigenetic studies is possible a diagnosis of their present situation,

5. Analise silvigenica em floresta estacional semidecidua e em cerradão no estado de São Paulo / Silvigenic analysis in seasonal semidecidous forest cerradão in the state São Paulo, Brasil
Studies of silvigenic mosaics based on the analysis of tree architecture, presumed to represent reations to the stimulus due to the light entrance in the forest canopy, have been suggested to investigate the mechanisms involved in the construction of tropical forests mosaic patterns. The identification of the eco-units (patches of trees of same architectural

6. Critérios para avaliação da qualidade de sedimentos - Estudo de caso: Sub-bacia do Ribeirão Espírito Santo, afluente do Rio São Francisco / Criteria for evaluating sediment quality - Case Study: Sub-Watershed of Espírito Santo Stream; Affluent of the São Francisco River
Sediment Quality Values Guidelines (SQVG) have been used for evaluating ecological risk associated with the sediment contamination for benthonic organisms. The main objective of this work was to develop methodologies and to collect data that allowed the application of SQVG for the following metals: Cd, Cu, Pb, Ni and Zn. The location chosen for the case stud

7. State and third sector in the organization of the space for tourism in the Valley of the Ribeira / Estado e terceiro setor na organização do espaço para o turismo no Vale do Ribeira
The present research is a study case of the region of the Valley of The Ribeira, located in the south of São Paulo state. The regions population is about 400.000 habitants and it presents the lowest rates of human development in the richest state of the country, consisting in a "cloudy area" inside the Concentrated Region. Containing about 20% of the forest

8. Áreas protegidas e turismo, estudo de caso: Parque Nacional do Pantanal Motogrossense/MT e seu entorno.
In Brazil, as in other parts of the world, the appeal of visiting protected areas has significantly grown in the last few years, especially in National Parks which require adequated planning and management action to deal with this increased pressure. This study analyses the types of tourism, and the role of the residents in the immediate surrounding area, wh

9. Planejamento e projeto de sistemas sustentaveis para produção de alimentos pela abordagem do ecodesenvolvimento : bases metodologicas e estudo de caso
A methodology is proposed for conception, planning and project of agro-industrial systems, in order to design them as "sustainable" taking into account their economic efficiency, relationship with ecosystem and quality of life offered to population involved in production and consumption. The methodology developed has the support of several theoretical concep

10. Location of Homologous DNA Sequences Interspersed at Five Regions in the Baculovirus AcMNPV Genome
An examination of Autographa californica nuclear polyhedrosis virus DNA revealed the presence of five interspersed regions, rich in EcoRI restriction sites, which shared homologous sequences. These homologous regions (hr), designated hr1 to hr5, occur at or near the following EcoRI fragment junctions: hr1EcoRI-B—EcoRI-I (0.0 map units); hr2, EcoRI-A—EcoR

11. Localization of a herpes simplex virus neurovirulence gene dissociated from high-titer virus replication in the brain.
Previous studies with the herpes simplex virus type 1 X type 2 intertypic recombinant RS6 suggested that the genomic region from 0.11 to 0.14 map units is involved in neurovirulence (R. T. Javier, R. L. Thompson, and J. G. Stevens, J. Virol. 61:1978-1984, 1987). To study this further, we isolated an RS6-derived herpes simplex virus intertypic recombinant (R1

12. Comparative structure and evolution of goat and sheep satellite I DNAs.
The satellite I DNAs of domestic goat (Capra hircus) and domestic sheep (Ovis aries) have been studied using molecular hybridisation and restriction enzyme analysis. Both satellite DNAs are composed of repeat units of 820 base pairs in length, but their restriction maps, although similar, differ in certain respects. Thus the majority of sheep satellite I rep
