| Abstract: The objective of this work was to evaluate the influence of topsoil thickness, shading and origin when performing environmental restoration in a degraded pasture area. The experiment was conducted in a randomized block design with a factorial (3 x 2 x 2) + 2 layout. Treatments consisted of combinations of topsoil origins (forest at early or middle regeneration stages), topsoil thicknesses (10, 20, or 30-cm superficial soil layer), and presence or absence of 70% shading; with two additional control treatments. Surveys on topsoil physical-chemical attributes and flora and soil coverage were conducted. Good correlation was observed between bulk density and total porosity. Vegetation comprised a total of 2,932 individuals of herbaceous, shrub and... |

| Lychnophora pohlii Sch. Bip. (Asteraceae), known as "Arnica mineira", is widely used in folk medicine and very abundant in the altitude vegetation of rocky grassland. The aim of this work was to study the density of this species and its relationship with soil parameters in rocky grassland in Diamantina, in the Upper Jequitinhonha region, Minas Gerais. Ten contiguous 20 x 50 m plots were marked (total sampled area 10,000 m²) on the campus Juscelino Kubitschek of the Federal University of Jequitinhonha and Mucuri Valleys (UFVJM). The plants in these plots were evaluated for frequency, dominance and density. The relationship between the density of this species with nine soil physical and chemical properties was analyzed by means of canonical correspondence... |

| O presente trabalho foi desenvolvido em um remanescente de caatinga hipoxerófila localizado na fronteira dos Municípios de Areia e Remígio--PB, com o objetivo de estudar o comportamento da regeneração natural em ambientes com diferentes níveis de perturbação antrópica. Foram selecionados três ambientes (I, II e III), ordenados em níveis crescentes de perturbação, tendo sido plotadas 5 unidades amostrais em cada um deles. Foram estabelecidas quatro classes de tamanho para estratificação dos indivíduos a serem estudados, conforme descritas a seguir: classe 1 - indivíduos com altura de 0,10 a 0,29 m; classe 2 - indivíduos com altura de 0,30 a 1,49 m; classe 3 - indivíduos com altura de 1,5 a 3 m e classe 4 - indivíduos com altura superior a 3 m, mas que... |

| O levantamento florístico e fitossociológico dos componentes arbóreo-arbustivos, em uma área de floresta no agreste paraibano, foi feito utilizando-se 30 parcelas de 10 x 20m, distribuídas por todo remanescente, e tomando-se os dados de altura total e diâmetro do caule ao nível do solo (DNS) de todos os indivíduos existentes nas parcelas, inclusive os mortos ainda de pé, com altura <FONT FACE=Symbol>³</FONT> 1m e DNS <FONT FACE=Symbol>³</FONT> 3cm. Foram registrados 1952 indivíduos, pertencentes a 22 famílias, 38 gêneros e 54 espécies. As famílias de maior destaque, com relação ao número de espécies e indivíduos foram: Mimosaceae (6); Euphorbiaceae (6); Caesalpiniaceae (5) e Rubiaceae (5). A densidade total, área basal total,... |

| ABSTRACT Rupestrian complexes of the Serra do Espinhaço are recognized for their high degree of biodiversity and endemism. However, environmental impacts, particularly from mining, have degraded these environments. The purpose of this study was to describe the herbaceous-subshrub communities that occur in quartzitic (QRC) and ferruginous (FRC) rupestrian complexes in different seasons of the year, with regard to floristic similarity and phytosociological structure. Additionally, the study aimed to identify native species with potential use for the restoration of similar degraded areas. Vegetation was sampled from plots located in the municipality of Conceição do Mato Dentro, state of Minas Gerais. Five contiguous strata of 10 × 50 m were demarcated in each... |

| Historically, forest landscapes have been modified by human activities, causing its destruction and fragmentation to exploit its resources. However, forests play a vital role in protecting the environment, especially on slops, hilltops, lakes, springs and river banks. This study aimed to understand the diversity and structure of vegetation on a slope of riparian forest in Bocaina de Minas, MG and identify key environmental variables that influence the spatial distribution of individual trees. An inventory of the tree community was conducted, in which ten of 10m×40m plots were allocated and systematically distributed throughout the study area. All individuals existing shrubs and trees within the plots with 1.30m diameter ≥ 5.0cm of soil were sampled in... |

| ABSTRACT: Translocation of rare populations is regarded as the last resort for the conservation of species whose habitat destruction is imminent. The objective of the present study was to evaluate the effect of two height classes and three leaf reduction intensities on growth and increases in height, stem diameter, survival, and new leaf production in seedlings of Aspidosperma cylindrocarpon (peroba) obtained via rescue seedlings in a remnant of tropical semi deciduous forest. We recovered 240 individuals that were divided into two height classes (Class I-5 to 15cm and Class II-20 to 35cm) and subjected to three leaf reduction intensities (0%, 50%, and 100%), which were then transported to a shade house with 50% light reduction. Measurements of height,... |

| O objetivo do trabalho foi avaliar o uso da Amostragem Adaptativa Cluster (AAC) na quantificação de indivíduos adultos de Caryocar brasiliense Camb. (Pequi), em comparação aos métodos de amostragem tradicionais. Foi feito um censo com mapeamento dos indivíduos adultos de pequi em uma área de cerrado de 36,5ha no Parque Estadual do Rio Preto/MG. O mapa gerado foi divido em unidades de 20×20m no qual foram testadas cinco alternativas de amostragem utilizando a Amostragem Casual Simples, Amostragem Sistemática e Amostragem Adaptativa Cluster. A comparação entre elas foi feita através do teste F de Graybill a 1% de significância, considerando os parâmetros precisão e exatidão. Todas as alternativas apresentaram boa exatidão, sendo a Amostragem Adaptativa... |
