13. Physical, structural and floristic diversity of forest fragments in the upper basin of the Rio Araguaia / Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
The upper Araguaia river basin region has been transformed by rapid and intensive human occupation processes that began in the 1970s, and now the landscape is highly fragmented. Remnant forests are surrounded by cotton and soybean plantations and pasture. They continue to be subjected to degradation and little is known about their ecological integrity. The o

14. Caracterização física, estrutural e da diversidade floristica de fragmentos florestais na alta bacia do Rio Araguaia
A região da alta bacia do rio Araguaia vem sendo objeto de profundas transformações relacionadas ao processo de ocupação rápida e intensa das terras a partir do final dos anos 70. Atualmente a paisagem nesta região, encontra-se completamente fragmenta. As ilhas de vegetação remanescentes, em sua maioria estão isoladas, cercadas por culturas agríco

15. Estratégias de análise da diversidade em germoplasma de cajueiro (Anacardium spp. L.) / Strategies for evaluating the diversity in germplasm of the cashew (Anacardium spp. L.)
The cashew (Anacardium occidentale) is a perennial arboreal fruit tree that is actually cropped in several tropical countries around the World. The Brazilian territory is probably the original and main diversity center of this tree fruit, as well as for most species of the genus Anacardium. On the other hand, studies concerning to the evaluation and characte

16. Floristics and phytosociology of Woody Species in a Campo Cerrado vegetation at Canchim farm (southeastern Brazil). / Florística e Fitossociologia das Espécies Lenhosas no Cerrado da Fazenda Canchim (São Carlos, SP)
The situation of the remaining cerrado areas in Brazil is worrisome, and more studies are necessary to establish effective conservation strategies. We studied several aspects of the Woody species in two campo cerrado areas in order to assess the conditions of the vegetation. We placed five permanent 10 x 10 m plots in each area, in which we sampled the woody

17. Caracterização genética de populações de cupuaçuzeiro, Theobroma grandiflorum (Willd. ex. Spreng.) Schum., por marcadores microssatélites e descritores botânico-agronômicos. / Genetic characterization of cupuassu theobroma grandiflorum (willd. ex. spreng.) schum. populations by microsatellite markers and botanic-agronomic descriptors.
This work had the objectives to characterize and compare the genetic structure of seven populations of cupuassu, Theobroma grandiflorum (Willd. ex Spreng.) Schum., a fruit tree native to the Brazilian Amazon using microsatellite markers and botanic-agronomic descriptors; and to investigate the cupuassu mating system. The genetic structure of seven population
