Accessing Next Generation Entomology

a plea for taxonomists to modernize their approach and explore new frontiers with ecologists

ABSTRACT. For collaborating taxonomists and ecologists, recent advances in molecular sequencing technologies open up new avenues in the discovery of biodiversity and our understanding of the laws that govern the evolution of organisms. The aim of my talk is to present new methods that may revolutionize our approaches of systematics, phylogenetics and community ecology. I will focus on three methods and illustrate my talk with examples taken mostly from our research projects. These methods are 1) Exon capture which may contribute efficiently to decipher evolutionary relationships between insect groups at different levels of the tree of life; 2) Restriction site Associated DNA Sequencing (RAD-seq) that may help to resolve shallow phylogenetic relationships in non model insect groups, delimit species boundaries and analyse hybridization processes (among others); 3) High-throughput Multigenic Barcoding by MiSeq amplicon sequencing that is presently developed for community ecology studies. This latter method may contribute to a better understanding of whom eats whom in insect food webs, and may help to understand how food web structure (parasitoids + predators) associated with target insect species vary in time and space. These methods also open a Pandora’s box of analytical issues, that I will discuss and that need urgently to be explored to avoid being misled. I wish this seminar will provide an opportunity to explore these topics with all of you and I encourage you to an open and free discussion that may open new perspectives.
