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. Leaf structural traits of three species of Qualea Mart. (Vochysiaceae) in a cerradão area in the Cerrado-Amazonian Forest transition
Resumo Qualea é um gênero comumente encontrado em diferentes fisionomias do cerrado brasileiro, crescendo em ecossistemas abertos até áreas florestais fechadas, sujeitos à alta irradiância, incêndios, baixa disponibilidade de nutrientes e deficit hídrico sazonal. Comparam-se aqui, atributos estruturais foliares de Qualea grandiflora Mart., Qualea mul

3. Tamaulipan thornscrub after fire: an analysis of the composition of species
Resumo Os incêndios florestais são um elemento natural em muitos ecossistemas terrestres, no México uma das principais causas de perda de cobertura vegetal está relacionada a eles, no entanto, nenhuma pesquisa foi realizada nas comunidades de espinheiros de Tamaulipan sobre as estratégias regenerativas pós-fogo de espécies de plantas, portanto, é imp

4. Post-fire recovery of a dense ombrophylous forest in Amazon
Abstract: The fires that occur in the Amazon are as damaging as the deforestation is. There is a need for further long-term studies on dynamics of tree communities in forests affected by fires. In the present study we evaluated the dynamics of tree species, before and after an accidental fire that occurred in 1997 in an experimental area of terra firme fores

5. Levantamento de plantas de baixa inflamabilidade em áreas queimadas de Cerrado no Distrito Federal e análise das suas propriedades físicas
Resumo Os incêndios florestais se propagam principalmente através do material combustível superficial. Portanto, plantas de baixa inflamabilidade podem ser usadas para proteção contra incêndios, pois dificultam a propagação do fogo. Neste sentido, o objetivo deste trabalho foi realizar um levantamento de plantas de baixa inflamabilidade no cerrado do

6. Influência dos Elementos Meteorológicos Sobre o Comportamento do Fogo
Resumo Os incêndios florestais geram problemas em diversas escalas em todos os ecossistemas. é amplamente reconhecido que quanto mais se entender sobre o comportamento do fogo e sua resposta às condições ambientais, mais acertadas serão as decisões sobre a gestão dos incêndios. O objetivo deste estudo foi avaliar o comportamento do fogo e suas corre

7. Comparison of Forest Fire Profiles in Londrina, Brazil and Pisa, Italy
ABSTRACT The main aim of this study was to compare the historical profile of forest fires and to elaborate a risk zoning map for the regions of Londrina, Brazil, and Pisa, Italy in the period from 2005 to 2014. The records of fire occurrences were correlated with days of rain and temperature in the study areas. The results showed that 1,435 and 629 fires wer

8. Forest Fire Hazard in the Serra do Brigadeiro State Park (MG)
ABSTRACT The objective of this study was to analyze the effectiveness of forest fire hazard indices for the Serra do Brigadeiro State Park region (MG). Although no weather station is present in this territory, the use of data obtained in the municipality of Viçosa (38 km distance) was effective to calculate the hazard. According to the results, the use of h

9. Effects of exposure to fine particulate matter in elderly hospitalizations due to respiratory diseases in the South of the Brazilian Amazon
Exposure to air pollution is an important cause of hospital admissions due to respiratory diseases. Nevertheless, few studies use pollutant concentration data estimated by mathematical models. A time-series ecological study was developed, using data from hospitalizations due to respiratory diseases in people over 60 years of age, residents of Cuiabá, Brazil

10. Floral and reproductive biology of Alcantarea nahoumii (Bromeliaceae), a vulnerable endemic species of the Atlantic Forest
ABSTRACT Alcantarea nahoumii occurs exclusively in the state of Bahia, Brazil, and is classified as vulnerable due to deforestation and frequent fires in the region. Knowledge of floral and reproductive biology is fundamental to understanding ecological interactions, as well as the reproductive success of plant species. The objective of this study was to eva

11. Estoque de combustível fino e decomposição de folhas em florestas de igapó do rio Negro / Fine fuel load and leaf decomposition in Rio Negro floodplain forests
In years of low rainfall, fires have occurred in Amazonian black-water floodplain forests, including the Middle Rio Negro. The fires are documented from satellite images. Forest fires require ignition sources, fuel and dry weather. To understand the susceptibility of these forests to fire we investigated the stock of fine fuel on the ground at 29 sites in bl

12. Análise integrada do uso e aptidão agrícola dos solos na Amazônia Legal visando o desenvolvimento sustentável
Encroachment of the agricultural frontier over the Brazilian Amazon (Amazônia Legal) forest and savanna (cerrado) areas generates an array of negative environmental impacts, such as deforestation and fires. The conflict between the pressing agricultural front, mainly represented by cattle and soya productions, and the preservation of such forest and cerrado
