Aix-Marseille Université - MARS herbarium – Cytogenetic data-base

Latest version published by Université d’Aix-Marseille on Jun 28, 2016 Université d’Aix-Marseille

Les variations chromosomiques concernent 90% des Ptéridophytes et 50 à 60% des Angiospermes. Il s’agit de processus fondamentaux de différenciation et de spéciation. Sur le plan taxonomique ces variations chromosomiques ont largement contribué à améliorer les classifications tandis que sur le plan évolutif, la compréhension de ces variations a permis de mieux cerner l’origine et l’histoire de certains groupes. Ainsi la base de données MARS-CYTO de l’Université d’Aix-Marseille a pour objectif de mettre à la disposition des chercheurs, via le portail du Gbif, les nombres chromosomiques et les informations relatives aux témoins herbiers, support de ces cytotypes. Cette base concerne essentiellement la flore du Bassin Méditerranéen : flore endémique insulaire, flore de Provence (SE. France), espèces rares et menacées et espèces invasives en France. Elle comporte également quelques monographies. Chromosomal changes concern 90% of pteridophytes and 50-60% of angiosperms. These are fundamental processes of differentiation and speciation. Concerning taxonomy, these chromosomal variations have contributed significantly to the improvement of classifications, while from an evolutionary standpoint the understanding of these variations has helped us to better identify the origin and history of certain groups. Thus the goal of the MARS-CYTO database of the University of Aix-Marseille, available via the GBIF portal, is to make available to researchers chromosome numbers and related information about plant specimens (herbarium) supporting these cytotypes. This database covers mainly the flora of the Mediterranean Basin: endemic flora of Mediterranean islands, flora of Provence (south-east France), rare and endangered species and invasive species in France. This database also contains several monographs.

Data Records

The data in this occurrence resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 1,004 records.

This IPT archives the data and thus serves as the data repository. The data and resource metadata are available for download in the downloads section. The versions table lists other versions of the resource that have been made publicly available and allows tracking changes made to the resource over time.
