The study aimed to evaluate the growth and reproduction strategies of the understorey palm species, Geonoma schottiana, based on allometric relationships and under different light conditions, in a semi-deciduous Atlantic forest. For this purpose, architectural parameters of 25 fruiting individuals were sampled, from which the number of fruits and infructescences were counted. The following parameters were also estimated: forest stratification, canopy (height and openness), crown variants (diameter, depth, openness and volume) and total height of the palm. A significant increment was found in the number of fruits with the increase in canopy opening and crown depth, while the number of infructescences increased with the total height of the palm. The proportion of variance explained by the number of infructescences was higher than that which was explained by the number of fruits. It was concluded that the fitness (i.e. production of fruits and infructescences) of G. schottiana is greatly influenced by the size of the individual (crown depth and total height) and canopy opening.

Currently, however, the management of these wastes is a complex issue due to the high urban expansion, the large amount and diversity of waste produced, limited public resources and limitations of energy and natural resources. The aim of this study was to investigate the current situation of solid waste management in Lavras’ microregion. Thus, the study was conducted using data obtained through visits to municipalities, consulting official information from national and state database such as IBGE and Fundação Estadual do Meio Ambiente. Based on these data, it was concluded that the Lavras’ microregion, integrated solid waste management is still evolving, once that most part of its municipalities still does an irregular final destination of the solid waste in lanfill, need to support recycling and waste pickers and feature non-conformities with the Law No. 12.305, which rules the National Solid Waste Policy. A more effective government action by requiring compliance with the items present in Law No. 12,305 and greater investment in creating awareness workshops of the population can help in the evolution of the management systems in the studied micro-region’s municipalities.

A taxon that stands out for these conditions, Lychnophora pinaster Mart. (Arnica-brazilian) is widely exploited for its therapeutic qualities. Thus, the present study was undertaken to elucidate the strategies of occupation of space by a population of L. pinaster, analyzing the traditional parameters of structure in multivariate analysis. For this purpose, 30 plots contiguous of 10mx10m were allocated in a Campo Rupestre stretch, inside of which DAS and the heights of all plants of that species were measured. The structural parameters obtained for the population were treated by simple Euclidean distance coefficient and then analyzed by UPGMA, complete linkage, and PCoA. Cluster Analyses showed consistency in large groups, set up in high levels of fusion. Among the tests performed, the UPGMA without the variable "volume" (C.Cf.=0.884539) determined six major groups to the fusion level 20, with three of them standing out by the differences in abundance, average height and diameter per plot. In this case, the ordination analysis revealed 74.94% of variance accumulated on an axis. Finally, Cluster Analysis by Complete Link for “tiller” (C.Cf.=0.730747), showed two major groups at fusion 17, determined by the irregular distribution of plots by individuals no affiliated. This distribution certainly reflects the conditions of the hilly topography and rock outcrops within the study area.

The study was conducted in two stands (B and C), each with 26and 38 10 m x 30 m plots. Censuses of stand B were conducted in 2000, 2005 and 2011,and stand C in 2001, 2006 and 2011. In both stands, the most abundant and importantspecies for biomass accumulation over the inventories were trees larger than 20 cm ofdiameter, which characterize advanced successional stage within the forest. The two surveyed stands within the studied forest presented differences in structure,diversity and species richness over the time.

To improve our knowledge of community composition, biomass stock and maintenance of gallery forests in the Brazilian Cerrado, we provide two datasets from the 0.5 ha Corrego Fazendinha Gallery Forest Dynamics Plot and the Corrego Fundo Gallery Forest Dynamics Plot situated in the Bom Despacho region, Minas Gerais, Southeastern Brazil. We report diameter at breast height, basal area and height measurements of 3417 trees and treelets identified during three censuses in both areas.

(Asteraceae), known as Arnica-mineira, is a plant widely used in popular medicine. Thus, in order to know the population structure of this species, was sampled a piece of Campo Rupestre in the Biological Reserve UNILAVRAS-Boqueirão, Ingaí, Minas Gerais. Therefore, were allocated 30 contiguos plots of 10 m x 10 m, with a total sample of 3,000 m². Individuals were evaluated for frequency, abundance, density, size classes (height and diameter) and spatial distribution. For size classes highlighted the smaller individuals of the population as the most abundant, indicating the regenerative potential of the plant and the predominance of vegetative propagation in the group. The highest abundances were found in plots 18 (78 ind.), One (73 ind.) and 28 (66 ind.). It was also observed a frequency equal to 96.7% in the distribution of individuals in relation to the plots. The species L. pinaster showed aggregated distribution pattern, with positive spatial autocorrelation for short distances, and patches of approximately 87 m. In this study, we could assume that abiotic factors, such as fire, must have been the main determinants of population structure of the species, which showed abundant even under harsh soil and weather condition.
