SUMMARY:

The intensification of habitat loss has led to a decline in the world's entomofauna. Plant species diversity and facilitation between plants influence the basal trophic levels and are fundamental to the sustainability of the upper trophic levels. However, studies of these processes in forest ecosystems are still incipient, especially in tropical forests in the world's arid and semi-arid regions. In the Brazilian semi-arid region, the process of habitat loss is intensifying due to desertification. Ecological restoration, based on the reconstruction of biodiverse vegetation in terms of the number of species and morpho-functional characteristics, is a fundamental process in the mitigation of these ecosystems from a multi-trophic perspective. The aim of this study is to investigate how the species diversity and functional diversity of the vegetation as well as facilitation processes are influencing the abundance, species richness and functional diversity of insects in a Caatinga restoration experiment focussed on biodiversity and function (BEF-BrazilDry). A positive effect is expected from the different ecological mechanisms of the effect of biodiversity in plant communities on insects by increasing the availability and variety of resources. Using Generalised Linear Mixed Models (GLMM), it was found that insect abundance is positively influenced by the joint increase in tree richness and facilitation. Insect species richness suffered a marginally significant positive effect from the interaction between tree richness and facilitation. The functional complementarity of insects suffered a marginally significant negative effect from the functional complementarity of plants. Our results suggest that in addition to the number of species, the type of interaction these species have is also important for the upper trophic levels. Forest maturity may enhance the effects of plant biodiversity analysed here on species richness and insect functional complementarity in the future. The restoration of dry forests should be thought of in terms of a high diversity of plant species, the processes of facilitation and functional complementarity, making the actions increasingly ecologically effective.
