1. Fire cues and germination of invasive and native grasses in the Cerrado
ABSTRACT Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and smoke water solution treatment on seed germination of invasive (Melinis minutiflora, Urochloa decumbens, U. brizantha) and nativ

2. 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

3. Fructan dynamics in the underground organs of Chresta exsucca (Asteraceae), a dry season flowering species
ABSTRACT Climatic seasonality has an influence on the phenology of native Cerrado plants. Herbs and subshrubs tend to flower in the rainy season, although some species of these habits flower in the dry season. Reserve carbohydrates, stored in the underground organs, are used to support phases of high energy-demand, but also may protect plants from damage dur

4. Post-fire resprouting strategies of woody vegetation in the Brazilian savanna
ABSTRACT Post-fire response by vegetation may reflect the severity of the damage suffered, but we still know little about the species-specific nature of responses to fire or their predictors. Here, we evaluated 26 woody species before and after a fire event in an Cerrado sensu stricto area (typical Brazilian savanna-type) in order to evaluate mortality rates

5. How does resprouting response differ among three species of savanna trees and in relation to plant size?
ABSTRACT Cerrado tree species can survive fire by resprouting. Generally, large and less damaged plants produce new branches and leaves from stem buds (aerial), whereas small and highly injured individuals would resprout from the stem base or from underground organs (basal). We compared the three most common Cerrado woody plant species in a savanna area of t

6. Anatomia ecológica e dendrologia de Eugenia sonderiana O. Berg e Eucalyptus saligna sm. na Serra do Cipó MG
Studies of the wood are valuable for many areas of botany, such as systematic and anatomy, being this last one, the focus of this work. The wood is able to record the environmental variations expressed through the cambium activity, allowing the retrievement of climate data of earlier times. Individuals from a plantation of Eucalyptus saligna located in the P

7. Resprouting ability and intensity after damage in seedlings of the large-seeded species Araucaria angustifolia
The role of seed reserves on the ability to resprout and on the responses of resprouting in Araucaria angustifoliawas investigated. Seedlings were separated into three groups: plants which had their shoot damaged, a similar group in which damaged plants had their connection to the supporting seed removed, and a control group. All damaged seedlings resprouted

8. Padrões de coocorrência de espécies vegetais de cerrado em diferentes regimes de fogo
Fire plays an important role in determining the structure of cerrado. Annual and biennial fires favor herbaceous species and constrain woody species. As a consequence, frequent burnings are expected to change the pattern of cooccurrence of plant species. We tested (1) whether high fire frequencies increase the number of occurrences of herbaceous and shrubby

9. Morfoanatomia, perfil químico e propagação de Smilax fluminensis Steud. (Smilacaceae) / Morph-anatomy, chemical profile and propagation of Smilax fluminensis Steud. (Smilacaceae)
As espécies do gênero Smilax L., conhecidas popularmente como salsaparrilha, são empregadas na medicina popular desde o século XVI, porém essas plantas ainda são exploradas de maneira extrativista. Com o aumento da comercialização de plantas medicinais cresce a necessidade de trabalhos que certifiquem a qualidade da matéria prima. A caracterização

10. Efeito da aplicação de percolado de resíduo sólido urbano em solo cultivado com capim-tifton 85 / Effect from the application of the municipal refuse percolate on the soil cropped with Tifton-85 grass
The effects from the application of different percolate rates of municipal solid waste (RSU) on the chemical characteristics of the soil, productivity and mineral composition of the tifton- 85 grass (Cynodon spp) were evaluated. The experiment was conducted in the Experimental Area for Treatment of Residues pertaining to the Department of Agricultural Engine

11. Experimental clipping of Chromolaena pungens (Asteraceae) and its multitrophic effects / Poda experimental de Chromolaena pungens (Asteraceae) e seus efeitos multitroficos
Natural or human-induced disturbances may promote plant phenotypic modifications, developmental and phenological changes which, in turn, may influence herbivores, predators and pollinators. Abiotic factors, especially nutrient availability, may also influence plant recovery. In this study, we evaluated plant regrowth and arthropod responses to experimental c
