Understanding the dynamics of endemic tree component species based on natural regeneration (NR) and adult trees (AT) is essential for formulating conservation strategies for protecting these species. The objective of the present study was to identify endemic species in a preserved area of secondary forest in the Atlantic Forest domain in Brazil and...

This study aimed to explore the physical and chemical attributes of the soil and to spatialize the soil organic carbon stock in a stretch of Atlantic Forest by evaluating four soil layers and the interrelationships of physical and chemical attributes as well as the spatialization of soil organic carbon stock by applying cokriging interpolation. Thu...

Litter layer is the layer of organic detritus accumulated on the soil in forest ecosystems and can be influenced by biologic, edaphic, and climatic factors, increasing from boreal forest to the tropics, and being highly related with the net primary production of forest. In the present study litter was analyzed in three topographic positions; the ef...

The diameter distribution of a forest makes it possible to understand its ecological processes and to define actions related to forest management aiming at forest conservation, biodiversity increase, production, and carbon sequestration, among others. This study aimed to identify variation in the diameter distribution in a secondary Atlantic Forest...

Agroforestry systems (AGF) design should benefit all components of the consortium. The objective of this study was to evaluate the effect of the distance between plants within the row on growth and yield of trees and agricultural crop and on the economic viability of the consortium. The eucalypt was planted in 9.5 x 1.5 m, 9.5 x 2.0 m, 9.5 x 3.0 m...

The growth of intact plants and coppice of juvenile plants of eight eucalypt clones (3 × 3 m spacing) was evaluated in the savanna region, Brazil (17°36′09″S and 46°42′02″W), aiming for biomass production for energy in short rotations.. The treatments included intact plants and juvenile plant coppice (cut at 13 months of age). Coppice was managed e...

The objective of the study was to quantify the accumulation of litter, macronutrients and organic carbon in the Submontane Seasonal Semideciduous Forest, located in Cachoeiro de Itapemirim, ES. A sampling of litter was performed in 12 plots (20 m x 50 m), and was distributed systematically in the field. In each of the 12 plots were collected monthl...

The objective of the study was to evaluate the soil fertility of a Submontane Seasonal Semideciduous Forest in three topographic gradients and correlate with the production and accumulation of these nutrients by litter, in the municipality of Cachoeiro de Itapemirim (ES). Soil samples for characterization of the 12 plots in the study were collected...

Resumo: O presente estudo teve por objetivos quantificar o aporte anual de serapilheira, macronutrientes e carbono orgânico em um trecho de Floresta Estacional Semidecidual Submontana, no Município de Cachoeiro de Itapemirim (ES), verificar a variação temporal de deposição de serapilheira e macronutrientes; e investigar a existência de correlações...

This study aimed at quantifying the annual production of litter, macronutrients and organic carbon in a section of Submontane Seasonal Semideciduous Forest in the municipality of Cachoeiro de Itapemirim (ES); checking the temporal variation of litter and macronutrients; and investigating the correlations between climatic variables and vegetation st...

Informações sobre Tabebuia heptaphylla são fundamentais durante a coleta das sementes e produção de mudas. Objetivou-se, no presente estudo, analisar a relação entre os fatores altura de coleta das sementes na planta, peso das sementes, posição da semente no substrato e tipos de substratos com as variáveis germinação de sementes e massa fresca de p...

Information about of Tabebuia heptaphylla can be important for seed collection and seedling production. The objective of this paper is to analyze the relationship between the factors height of harvesting on the tree, weight of seed and the position of seed germination of Tabebuia heptaphylla in the substrate, kind of substrate and the variables see...
