E-systematica is a participatory project who aims at inventorying all concepts that exists in systematics

Every article is written by an expert, specialist of the subject

The objects of the definitions of those articles only concern the concepts of the science of systematics (and not taxa descriptions nor their phylogenies).

Every concept (eg: species) can have multiple articles written by different authors. The purpose is to illustrate the diversity and richness of the different school of thoughts in systematics.
