Abstract: The purpose of this study was to determine the influence of land use types on nematode assemblage in sugarcane production in Pernambuco State, Brazil. One forest and two managed agricultural soils were characterized by their nematode assemblages to assess their biological characteristics. Soil samples were collected between 2009 and 2010 at three 10-cm depth increments along two 200-m transects with points at 20-m intervals from each other. Nematodes were extracted by sucrose centrifugation, and the physical properties of the soil were analysed, including soil mechanical resistance, bulk density, total porosity, water content, and texture. The effects of agricultural land management on the soil’s physical properties and nematode assemblage composition were significant. Soil mechanical resistance has critical implications for the abundance and distribution of plant-parasitic nematodes in agricultural soils. Thus, a new approach is needed for the design and management of an integrated ecosystem mainly to optimize antagonistic systems to plant-parasitic nematodes.

Clayton Alcarde Alvares,José Luiz Stape,Paulo Cesar Sentelhas,José Leonardo de Moraes Gonçalves,Gerd Sparovek +4 more
TL;DR: In this article, the authors developed a geographical information system to identify Koppen's climate types based on monthly temperature and rainfall data from 2,950 weather stations in Brazil, and the results are presented as maps, graphs, diagrams and tables, allowing users to interpret the occurrence of climate types in Brazil.
The Brazilian Atlantic Forest:: how much is left and how is the remaining forest distributed? Implications for conservation

TL;DR: In this paper, the authors quantify how much of the Brazilian Atlantic Forest still remains, and analyze its spatial distribution, and suggest some guidelines for conservation: (i) large mature forest fragments should be a conservation priority; (ii) smaller fragments can be managed in order to maintain functionally linked mosaics; (iii) the matrix surrounding fragments, and (iv) restoration actions should be taken, particularly in certain key areas.
