1. Efectos del fuego en el arbolado de un bosque tropical de pino y en el de una selva baja caducifolia en Villaflores, Chiapas
Abstract It is expected an increase of forest fires world-wide because of global warming. So is important the study of fire ecology and fire effects in different ecosystems. In Villaflores, Chiapas, Mexico, are conducted efforts towards the integral fire management. There was studied a Pinus oocarpa Schiede forest, as well as a tropical dry forest, affected

2. Factors influencing seed germination in Cerrado grasses
Few studies address the ecology of herbs of Cerrado grasslands, which are ecosystems where the long dry season, high temperatures, insolation, fire and invasive grasses greatly influencing germination and the establishment of plants. We assessed germination of 13 species of Poaceae from Cerrado grasslands under nursery conditions or in germination chambers,

3. Ecology, management and conservation of buriti (Mauritia flexuosa; Arecaceae) in swamp forest of the Central Brazil / Ecologia,manejo e conservação do buriti (Mauritia flexuosa; Arecaceae) nos brejos do Brasil Central
Florestas geram subsistência e renda para comunidades rurais, por meio do extrativismo de produtos florestais não madeireiros (PFNM), agricultura de coivara, criação de gado e porcos, etc. Estas atividades podem ser alternativas econômicas de menor impacto do que o corte seletivo de madeira e a conversão das florestas em monoculturas. Porém, a sustent

4. Impact and regeneration mechanism after invasion by Pteridium arachnoideum (Kaulf.) Maxon (Dennstaedtiaceae) in savanna woodland areas, southwestern São Paulo State / Impacto da invasão e mecanismos de regeneração natural do cerradão em áreas ocupadas por Pteridium arachnoideum (kaulf.) Maxon (Dennstaedtiaceae) no sudoeste do Estado de São Paulo
The genus Pteridium comprises bracken species recognized by large fronds and a rhizome system that allows their fast expansion. Bracken presents an elevated biomass production throughout the year, that increases fire occurrence and release chemical compounds that are considered allelopathic. Nowadays, species of the genus Pteridium are well known as problem-

5. Diversidade funcional: como incluir a variação intraespecífica e o efeito do fogo em comunidades vegetais do cerrado
Biological diversity may influence the structure and functioning of communities in several ways, for example, altering the species resource complementarity. However, traditional diversity measures (such as species richness or diversity indices as Shannon or Simpson) have being considered as rough biodiversity estimators. In that sense, several authors sugges

6. Estimativa populacional , seleção de habitat, distribuição e conservação do cervo-do-Pantanal nas savanas do norte da Bolivia
The biggest cervidae in South America, the marsh-deer (Blastoceros dichotomus(Blastoceros dichotomus) shows reductions in its distribution and historic population, principally due to human environmental disturbances. Research related to population size and ecology were developed only in Brazil and Argentina, and there is no published data for the other count

7. Fogo, fenologia foliar e a fauna de lagartas em Byrsonima coccolobifolia kunth (malpighiaceae)
Despite the abundance of lepidopteran species, there are few studies focusing on lepidopteran caterpillars, such as their biology, the interactions with their host plants and the effects of fire on their community structure in Cerrado. The aim of the present study was to evaluate the effects of fire on foliar phenology of Byrsonima coccolobifolia Kunth (Malp

8. Fauna do solo e outros atributos edáficos como indicadores da qualidade ambiental em áreas com Araucaria angustifolia no Estado de São Paulo / Soil fauna and others edaphics attributes as environmental quality indicators in areas with Araucaria angustifolia in São Paulo State, Brazil
The study of biological soil quality indicators in areas with Araucaria is very important to understand ecological processes in these systems, since groups of the soil fauna are major factors in the decomposition and mineralization of organic matter, as well as modifiers of soil physical, chemical and biological properties and processes. The objective of thi

9. Ecologia de Solenopsis invicta Buren (Hymenoptera: Formicidae) em um agroecossistema diversificado sob manejo orgânico. / Ecology of Solenopsis invicta Buren (Hymenoptera: Formicidae) in an agroecosystem.
Solenopsis invicta Buren (Hymenoptera: Formicidae) (formiga-lava-pé), espécie nativa da América do Sul, hoje ocorre na América Central, América do Norte e Oceania. A espécie é considerada uma praga importante devido às altas densidades populacionais, agressividade e à sua picada desagradável, podendo provocar reações alérgicas. A espécie pode t

10. Populational and taxonomical studies of fire ants, Solenopsis invicta (Hymenoptera: Formicidae), and of the phenology of their parasitoids of the genus Psedacteon (Diptera: Phoridae) / Estudos populacionais e taxonomicos de formigas lava-pes, Solenopsis invicta (Hymenoptera: Formicidae) e da fenologia de seus parasitoides do genero Pseudacteon (Diptera: Phoridae)
This work discusses some aspects of the ecology of the fire ant species Solenopsis invicta and its phorid parasitoid flies ofthe genus Pseudacteon, and ofthe taxonomy of S. invicta and S. saevissima, both of which are native to South America. The allometry of S. invicta colonies in southeast Brazil was studied by measurement of mound (aboveground) dimensions

11. Manejo e regeneração de trecho degradado de floresta estacional semidecidual : Reserva Municipal de Santa Genebra, Campinas, SP
The current study was performed in Reserva Municipal de Santa Genebra (RMSG), Campinas/SP(22° 48 36" S- 470 OT33 W), in an area burned in 1981. The RMSG has approximately 250 ha. The burned area, approximately 10 ha, does not present a forest physiognomy, instead it is characterized as having an overpopulation of lianas that form the vegetation and its pred

12. Ecologia da interação entre formigas invasoras e moscas parasitoides
The establishment of exotic species is an important disturbing factor of native community. The knowledge of the ecology of these invading species in their native range is fundamental to handle effectively the problem. The red fire ant, Solenopsis invicta Buren, and the Argentine ant, Linepithema humile (Mayr), are invading species in many places, bringing ec
