SYSTE - Systematics and biogeography of extant and fossil plants


Our work aims to inventory extant and fossil plant biodiversity, to understand the underlying processes at its origin, and to help preserve biodiversity in a global change perspective.

Our work consists in (i) documenting taxa characteristic of areas and time periods of high ecological or evolutionary interest, (ii) defining their morpho-anatomical and ecological characteristics, (iii) identifying their biogeographical origin, and (iv) researching the processes underlying current and past plant biodiversity. For extant floras, the main families studied are Amaryllidaceae, Asparagaceae, Eriocaulaceae, Lauraceae, Orchidaceae, Piperaceae, Poaceae, Rhizophoraceae, Rubiaceae, Sapindaceae, Sapotaceae, and Urticaceae. This work tries to have an integrative approach, combining morphology, anatomy, architecture, phenology, ecology, distribution, and to rely on methods of numerical taxonomy, molecular biology, and niche modelling. Knowledge of the ecology and distribution of taxa enables the prediction of future distributions in response to ongoing climate change. Work on fossil plants focuses both on pre-angiosperm floras during warm periods in Earth's history (Paleozoic and early Mesozoic) and on the origin of extant vegetation (Cenozoic), with a focus on poorly sampled geographical areas.

Our work benefits from research infrastructures such as the herbaria (notably CAY, NOU curated by AMAP), the palaeobotanical collection of the University of Montpellier, and AMAP's histology technical platform (extant & fossil). The main geographical sites are the Mediterranean region, South America, Central Africa, Kenya and Madagascar, and New Caledonia for the current floras; North Africa, Australia, Antarctica, and New Caledonia for the fossil floras. The work is based on the exploitation of pre-existing collections, field missions to acquire additional material (naturalist expeditions, fossil deposit excavations) or databases of species occurrences, possibly coming from citizen sciences (see for example Pl@ntNet).
