Plant and arthropod diversity in forest fragments with different levels of disturbance

Abstract : Brazil's Atlantic forest is a hot spot of biodiversity and its surface area is constantly being reduced for cultivation, causing a fragmentation of the forest landscape. For several years now, protection measures have been put in place and the restoration of forest fragments by their owners is controlled through the Brazilian Forestry Code. The study of these forest fragments is important to assess their importance in crop protection, but also to justify their preservation. There are several types of forest fragments and this study aims to study the fragments located along rivers and on plateaus. These two types of fragment have different preservation policies, and we hypothesised that variations in biodiversity and plant-arthropod interaction would be highlighted. We showed differences between the fragments, but the type of fragment did not explain these dissimilarities. These initial results enabled us to estimate several variables to measure the quality of forest fragments. We finally proposed a method for assessing this quality for the fragments studied, the results of which could make it possible to classify the fragments according to their restoration needs.
