L'alpha-taxonomie au XXI e siècle : Inventorier le Vivant à l'ère du numérique et de la 6e extinction.

Abstract : Halfway through a process of modernization undertaken some twenty years ago, the challenges facing contemporary α-taxonomy are multiple, and are as much quantitative (accelerating the inventory of living organisms) as qualitative (having reliable species hypotheses). They consist, among others, of: appropriation of concepts and techniques developed in evolutionary biology; standardization / objectivization / formalization of decision-making processes (when to describe a species hypothesis?); integration of new types of data (genome, transcriptome, Ctscan); and development of adapted digital tools (interoperable and specimen-centered databases, tools dedicated to species delimitation, assessment of confidence in species hypotheses, etc.). The extent of these changes and those to come also highlights the need to revise and strengthen the epistemological basis on which this multi-secular branch of biology rests. Beyond my works on squamates systematics (mainly phylogenies and integrative revisions of tropical skinks), this dissertation will focus on my generalist contributions, i.e. those addressed to all practitioners regardless of their field of specialization. After a presentation of the different notions related to the α-taxonomy and a historical overview intended to better measure the extent of the paradigm shift this discipline is going through, a detailed synthesis of my contributions to methodological or technical questions will be presented. They are addressing, among others, issues related to taxonomic data (characterization, management, sharing and integration) and to the objective comparison of partitions resulting from different species delimitation analyses.
