13. Antiproliferative activity in tumor cell lines, antioxidant capacity and total phenolic, flavonoid and tannin contents of Myrciaria floribunda
ABSTRACT Myrciaria floribunda (H. West ex Willd.) O. Berg, Myrtaceae, is a native plant species of the Atlantic Rain Forest, from north to south of Brazil. The lyophilized ethyl acetate extract from the leaves of M. floribunda was investigated for its antiproliferative activity in tumor cell lines, antioxidant capacity and its total phenolic, flavonoid and t

15. Halotolerant bacteria in the São Paulo Zoo composting process and their hydrolases and bioproducts
Halophilic microorganisms are able to grow in the presence of salt and are also excellent source of enzymes and biotechnological products, such as exopolysaccharides (EPSs) and polyhydroxyalkanoates (PHAs). Salt-tolerant bacteria were screened in the Organic Composting Production Unit (OCPU) of São Paulo Zoological Park Foundation, which processes 4 ton/day

16. Does nutrient cycling differ between fragments of Atlantic Forest with distinct structural aspects? A case study in the state of Rio de Janeiro, Brazil
In this study, we evaluate litter biomass and nutrient inputs, as well as nutrient use efficiency (NUE), in two fragments of dense montane rain forest within the Atlantic Forest Biome in the northern region of the state of Rio de Janeiro, Brazil. The total annual average litter production for the two fragments (designated M1 and M2) was 7.72 and 7.56 t ha−

17. Toward a better understanding of the subtropical Atlantic Forest in the state of Santa Catarina, Brazil: tree sampling accuracy, species richness and frequency of rare species
Accurate knowledge of floristic composition is crucial when planning and designing research projects and public policies. In this study, our goal was to assess tree sampling accuracy and to identify sites with higher concentrations of rare tree species, as well as those with the highest tree species richness, in the state of Santa Catarina, Brazil. We determ

18. Diversity of myxomycetes in an environmentally protected area of Atlantic Forest in northeastern Brazil
The present study was carried out on three trails, each presenting a different degree of disturbance, within the Pau-Ferro Forest Environmentally Protected Area, a 600 ha area of highland forest located in the municipality of Areia (06°58'12"S; 35°42'15"W; elevation, 400-600 m), in the state of Paraíba, Brazil. In 2005, we analyzed the species richness, a

19. A new species of Serracutisoma (Opiliones: Gonyleptidae: Goniosomatinae) from the coastal Atlantic Rain Forest of Paraná and São Paulo states, Brazil
Serracutisoma gnaspinii sp. nov. is described from the coastal Ombrophylous Dense Atlantic Rain Forest of Paraná and São Paulo states. It differs from other Serracutisoma by having a retrolateral row of spines on femur IV, a rounded white-mark on the carapace and a low dorsal apophysis on trochanter IV. It is likely the sister-species of S. proximum, and w

20. Seed rain in areas with and without bamboo dominance within an urban fragment of the Atlantic Forest
Understanding the flow of diaspores is fundamental for determining plant population dynamics in a particular habitat, and a lack of seeds is a limiting factor in forest regeneration, especially in isolated forest fragments. Bamboo dominance affects forest structure and dynamics by suppressing or delaying the recruitment of and colonization by tree species as

21. Anurans in a forest remnant in the transition zone between cerrado and atlantic rain forest domains in southeastern Brazil
O estudo apresenta a riqueza de espécies, distribuição temporal e atividade reprodutiva dos anfíbios anuros da Floresta Estadual do Uaimií situado na região do Quadrilátero Ferrífero, município de Ouro Preto, estado de Minas Gerais, Brasil. Foram realizadas campanhas mensais no período de Setembro de 2009 a Agosto de 2010. Foram registradas 36 esp�

22. Diversity and distribution of the bryophyte flora in montane forests in the Chapada Diamantina region of Brazil
Bryophytes constitute an important component of tropical rain forests, which provide microhabitats favorable for their establishment. Bryophytes are also quite responsive to changes in microclimate, which makes them good bioindicators. This study aimed to determine the diversity and distribution of bryophytes in upper and lower montane forests of the Chapada

23. A tutela da diferença no direito socioambiental pós-moderno: um estudo de caso sobre a prática da agricultura de corte e queima pela Comunidade Quilombola de Ivaporunduva / Tutelage of \"different/diverse\" communities in post-modern socioenvironmental right: a case study on slash and burn agriculture practiced by the Quilombola Community of Ivaporunduva, SP, Brazil.
This research aims at developing a thorough analysis of the Right that arose with modernity. Based on the hypothesis that even though Post-Modern Right autodenominates itself the advocate of diversity, it is still tied to the legality model of judicial positivism. The Right is ongoing an important crises, and at the time that eliminates customary rules, elim

Buscando entender a regeneração natural sob plantios homogêneos e a floresta nativa, esta pesquisa teve como objetivo analisar a sucessão ecológica da vegetação nativa em um remanescente de floresta ombrófila densa e em sub-bosques de Corymbia citriodora (Hook.) K.D. Hill &L.A.S. Johnson, a fim de fazer uma análise comparativa entre o papel destes p
