| The landscape of Mengsong, southwest China, was biologically diverse until recently due to historical biogeographical processes overlain by the swidden-cultivation practices of the Hani who migrated there several centuries ago. Our research sought to understand how the Hani adjusted their livelihoods to new policies, markets, and technologies, and the consequences for biodiversity conservation. We combined landscape, plot, and household surveys, interviews, and reviews of secondary documents, to reconstruct the major changes and responses to challenges in the social–ecological system over previous decades. Significant changes from closed to open canopy of secondary-forest vegetation took place between 1965–1993 and from open-canopy... |

| The objective of this work was to evaluate the influence of intercropping 'Conilon' coffee (Coffea canephora) with rubber trees on coffee tree microclimate, nutrition, growth, and yield. Rubber trees were planted in two double rows 33 m apart, with 4x2.3 m spacing between plants. Treatments consisted of the distances from the coffee plants to the rubber trees: 3, 6, 9, 12, and 15 m. Measurements of atmospheric variables (temperature, irradiance, and relative humidity), leaf nutrient concentration, internode length of plagiotropic and orthotropic branches, individual leaf area, chlorophyll content, and yield were performed. Intercropping promotes changes in the microclimatic conditions of coffee plants close to rubber trees, with reduction of temperature... |

| ABSTRACT There are few studies about the shading of Robusta coffee with rubber trees. The aim of this study was evaluate the microclimate, development and yield of Coffea canephora grown at full sun and shaded by rubber trees. The experiment consisted of a Robusta coffee crop (Coffea canephora) grown at under full sun and another coffee crop intercropped with rubber trees (Hevea brasiliensis). The rubber trees and coffee crop were planted in the East/West direction, in Jaguaré, Espírito Santo, Brazil. Was evaluated the luminosity, temperature and relative humidity, leaf nutrient concentrations; internodes of the plagiotropic and orthotropic branches, leaf area; relative chlorophyll index, and tree yield of the coffee crops. The shading directly influenced... |

| Sugarcane, which involves the use of agricultural machinery in all crop stages, from soil preparation to harvest, is currently one of the most relevant crops for agribusiness in Brazil. The purpose of this study was to investigate soil physical properties and root growth in a eutroferric red Oxisol (Latossolo Vermelho eutroférrico) after different periods under sugarcane. The study was carried out in a cane plantation in Rolândia, Paraná State, where treatments consisted of a number of cuts (1, 3, 8, 10 and 16), harvested as green and burned sugarcane, at which soil bulk density, macro and microporosity, penetration resistance, as well as root length, density and area were determined. Results showed that sugarcane management practices lead to alterations... |
