- ... Maintaining crop residues on the surface of soils with the possibility of renewing sugarcane fields could be a key factor for improving the structural quality of the soil. The objective of the present study was to assess the structural quality of soil after the use of alternative crops under a no-tillage system in the restoration of a sugarcane field, by the least-limiting water range (LLWR) and t ...

- ... Very little is known about how spatial effects influence invasive species throughout the invasion sequence. We propose here two mechanisms to explain the changes in spatial effects throughout the stages of invasion, using the soybean aphid (Aphis glycines) as a model. First, the “hierarchical spatial effect” hypothesis, based on a change in the relative importance of the spatial scales throughout ...
