13. Soil Seed Banks in a Forest Under Restoration and in a Reference Ecosystem in Southeastern Brazil
ABSTRACT The current study aims to characterize the soil seed banks in a forest under restoration and in a seasonal semideciduous forest remnant, as well as to quantitatively and qualitatively compare them in order to evaluate the seed bank potential to influence the restoration process. In total, 60 samples of soil seed banks were collected in two adjacent

14. Host tree bark traits and development of reintroduced Cattleya intermedia (Orchidaceae) plants in Southern Brazil
Resumo As características das cascas de árvores hospedeiras podem influenciar na distribuição e no desenvolvimento de epífitos. Amostras de casca foram suspensas em 10 e 20 mL de água destilada por 1, 4 e 24 h, para avaliação de métodos para a determinação do pH. Cascas de Myrcia brasiliensis, M. glabra e Myrsine coriacea hospedeiras de Cattleya i

16. Composición y estructura del dosel de sombra en sistemas agroforestales con café de tres municipios de Cundinamarca, Colombia
Abstract The composition and structure of the shade canopy in coffee plantations of the municipalities of Tibacuy, Pacho and San Juan de Rioseco, in Cundinamarca, Colombia, were studied. Fifteen (15) farms in each municipality were selected and, in each farm, a coffee plantation (Coffea arabica cv. Castillo), in which it was established a plot of 1000 m2, wh

17. Potential and Future Geographical Distribution of Eremanthus erythropappus (DC.) MacLeish: a Tree Threatened by Climate Change
ABSTRACT Eremanthus erythropappus is a commercially-important tree which has a long history of exploitation in the Brazilian State of Minas Gerais. The knowledge on the potential geographical distribution of E. erythropappus is therefore critical for the species sustainability. Thus, the aim of this study was to estimate and map current and future ecological

18. New record of the fringed leaf frog, Cruziohyla craspedopus (Anura: Phyllomedusidae) extends its eastern range limit
RESUMO A perereca franjada, Cruziohyla craspedopus é raramente amostrada na Amazônia brasileira, provavelmente devido à baixa probabilidade de detecção associada ao seu hábito arborícola. A distribuição geográfica conhecida da espécie é resultado da adição sucessiva de registros ocasionais de ocorrência, que indicam que ela é amplamente distr

19. Influence of Edaphic Attributes on the Distribution of Tree Species in a Riparian Forest in Southern Brazil
ABSTRACT This study aims at identifying the formation of clusters and to evaluate the influence of chemical attributes in the soil on the groups and species in a riparian forest fragment in Campos de Cima da Serra, Rio Grande do Sul (RS). Thirteen plots (10 × 20 m) were demarcated to carry out the study. Forest inventory data were employed in a multivariate

20. Climate Change Influencing the Potential Distribution of a Brazilian Savanna Indicator Species
ABSTRACT The objective of this study was to model the potential effect of future climate change on the distribution of a tree species indicator of Cerrado. For the modeling, we used 488 occurrence points of the species and also bioclimatic variables corresponding to 2050 and 2070, for the more optimistic and pessimistic scenarios. All generated models were c

21. Genome-wide identification, characterisation and expression profiling of the ubiquitin-proteasome genes in Biomphalaria glabrata
BACKGROUND Biomphalaria glabrata is the major species used for the study of schistosomiasis-related parasite-host relationships, and understanding its gene regulation may aid in this endeavor. The ubiquitin-proteasome system (UPS) performs post-translational regulation in order to maintain cellular protein homeostasis and is related to several mechanisms, i

22. Ancient and Current Distributions of Erythrina crista-galli L. (Fabaceae) in South America
ABSTRACT Erythrina crista-galli is a native tree from South America with an important role on pharmaceutical studies. The objective of this study was to model the ancient and current ecological niches distribution of E. crista-galli in South America, contributing to the discussion about species management and conservation. A reduction in the potential area o

23. Community structure and tree diversity in a subtropical forest in southern Brazil
Resumo: Variações ambientais locais e regionais levam à composição de espécies diferentes e áreas de transições. Um exemplo é a floresta com araucária e a floresta estacional no sul do Brasil. Nossos objetivos foram (1) descrever a composição e estrutura da comunidade arbórea de uma floresta subtropical no sul do Brasil e (2) comparar as relaç

24. Spatialization of Tree Species Diversity in the State of Minas Gerais
ABSTRACT The state of Minas Gerais has a high ecological relevance mainly due to its forest species diversity. Understanding the spatialization of that diversity is of importance to develop environmental public policies. The hypothesis of this study is that the tree species diversity from different forest types, in the state of Minas Gerais, presents distri
