SYSTE theme - Systematics and Biogeography of Plants

Description

Background

The knowledge of flora and their origin targets geographical sites in Africa (Mediterranean Maghreb and tropical Africa), South-East Asia (Laos, Indonesia), Asia Minor (Near and Middle East), South America (French Guiana) and Pacific (New Caledonia). In these regions where conservation issues are linked to a good knowledge of biodiversity, work on the systematics and distribution of plant species is part of a development aid policy and is carried out in collaboration with local or international partners. Indeed, these mega-diverse tropical and Mediterranean regions are subject to strong anthropogenic pressures. This research in modern systematics (integrated morphometric/molecular approaches) is also intended to be applied and to include: descriptions of taxa, study of their distribution, assessment of their conservation status. Botanical data management tools and identification tools (Pl@ntNet project) are being developed and a more fundamental biogeographical approach to understanding the origin of the studied flora is also being developed. This work is mainly based on the collections of the herbaria of Cayenne (CAY) and Nouméa (NOU), which we manage, as well as that of Montpellier (MPU).

Objectives

  •  Provide local partners with a better knowledge of their flora for better management.
  •  Understand the origins of these flora and the diversification processes.
  •  Develop local methods and expertise for the conservation in situ and ex situ (seed bank, shade) of rare or threatened species.
  •  Train local staff in research and naturalist expertise (training of teachers, co-supervision of students, etc.).

Expected Results

This work produces new knowledge that can be directly exploited by users and managers of the concerned flora, and of plant groups that are particularly problematic and important for these regions (Alliaceae, Cupressaceae, Fabaceae, Hyacinthaceae, Lamiaceae, Lauraceae, Orchidaceae, Rubiaceae, Sapotaceae, Sapindaceae).

Significant events

  •  Revision of 14 genera and description of 60 new species and one new genus from New Caledonia, Tropical America and Central Africa.
  •  Participation of V. Droissart in the Lengguru 2014 expedition to West Papua (http://www.lengguru.org/). ARTE Lengguru filmu (https://boutique.arte.tv/detail/papouasie_expedition_coeur_un_monde_perdu).
  •  Participation in the expeditions La Planète Revisitée in French Guiana in 2015 (J.-F. Molino, D. Sabatier, S. Gonzalez) and in New Caledonia in 2016 and 2017 (J. Munzinger et David Bruy).
