1. Estimação clássica e bayesiana para relação espécieárea com distribuições truncadas no zero
Em ecologia, a compreensão da relação espécie-área (SARs) é de extrema importância para a determinação da diversidade de espécies e avaliar o impacto devido à destruição de habitats naturais. Neste estudo, observa-se o número de espécies em diferentes tamanhos de área. Estes estudos são abordados na literatura através de modelos não linear

2. Padrões florísticos e estruturais das Florestas Estacionais Semideciduais do Triângulo Mineiro, MG / Floristic and structural patterns of semideciduous seasonal forests of Triângulo Mineiro, MG
The semideciduous seasonal forests (SSF) of southeastern Brazil have a high floristic diversity, accompanied by a high beta diversity, even between nearby fragments. However, nowdays these forests have been represented by a large number of small fragments, a landscape pattern typical for this region. In addition to the processes related to fragmentation, the

3. Modelagem da dinâmica de crescimento de uma Floresta Ombrófila aerta do estado de Rondônia / Modelling of growth dynamics of tropical rain forest of State of Rondonia, Brazil.
A model of the growth dynamics of forests was developed applying Bertalanffy growth model (BGM) y=a[(1ebt)c] for individual trees. Based on linearized relationship with diameter and height equation LnH=b0+LnD and volume equation V=b0Db1Hb2 mutually compatible equations for diameter, basal area, height and volume were generated, adjusting parameters a and c o

5. Idade, crescimento e uso do habitat das espÃcies Stegastes rocasensis, no Atol das Rocas e Stegastes sanctipauli, no ArquipÃlago de SÃo Pedro e SÃo Paulo
Although the importance of coral reef environments, it is known by scientists all around the world that this ecossistem is actually under potencial impacts and declining. A vital part of coral reefs ecossistems is composed by coral reef fishes. It is estimated that 30-40% of marine fishes can be found in coral reefs. The Pomacentridae family has an important

6. Modelos numericos para a descrição do crescimento da planta de soja (Glycine max L. Merril, cultivar IAC-15) em condições saxonais diferenciadas
The present work has the objective to show the survey of the Aristolochia species (family Aristolochiaceae), that occurs from spontaneous, subspontaneous and cultured forms within São Paulo State. The specific diagnoses was elaborated through data in herborized collections from several national and foreign Herbarium. Information about leaf anatomy of five s
