Introduction
I am a New Caledonian botanist interested in plant diversity, evolution and conservation in island systems. In addition to describe the New Caledonian flora through research in taxonomy, I am interested in the evolution of plant traits in Pacific lineages to highlight global evolutionary patterns explaining the actual diversity and originality of the New Caledonian flora.

Article
In the context of global change, tropical forests are increasingly affected by fires. Understanding the ecological processes driving forest recovery in fire-modified landscapes is a critical issue. We analyzed spatial and temporal (8 years) changes in functional and phylogenetic composition of tree communities during forest post-fire recovery in an...
Article
A new species, Garcinia urceolata Munzinger, Bruy & M.Pignal, sp. nov. (Clusiaceae), is described from New Caledonia. It is restricted to North Province, from the Tchamba valley in the south to Mandjélia in the north of the main island of Grande-Terre, occurring in dense humid rainforests on non-ultramafic substrate. Material of this small tree spe...

Background and aims – New Caledonia is a hotspot of biodiversity in the world. Among the most diverse New Caledonian plant families is Rubiaceae, which consist of 30 genera containing 220 species, with a level of endemism of 93%. The tribe Gardenieae is represented by four genera, Gardenia (8 species), Aidia (2 species), Randia (7 species), and Atr...
Chapter
New Caledonia is a biodiversity hotspot located in the southwest Pacific Ocean, recognized for the exceptional diversity of its vascular flora, comprising over 3400 species, 75% of which are endemic. Facing the daunting challenge of its preservation and in need of robust data to prioritize conservation efforts, botanists proposed the creation of a...
Article
The OCBIL theory comprises a set of hypotheses to comprehend the biota of old, climatically buffered, infertile landscapes (OCBILs). Here, we review evidence from the literature to evaluate the extent to which this theory could apply to the biodiversity hotspot of New Caledonia. We present geological, pedological and climatic evidence suggesting ho...

Plant traits—the morphological, anatomical, physiological, biochemical and phenological characteristics of plants—determine how plants respond to environmental factors, affect other trophic levels, and influence ecosystem properties and their benefits and detriments to people. Plant trait data thus represent the basis for a vast area of research sp...
Article
Full-text available
The diversification of ecological roles and related adaptations in closely related species within a lineage is one of the most important processes linking plant evolution and ecology. Plant architecture offers a robust framework to study these processes as it can highlight how plant structure influences plant diversification and ecological strategi...
Thesis
Full-text available
L’évolution convergente des formes de croissance est un phénomène fondamental reliant l’écologie et l’évolution des plantes. Remarquablement illustré dans plusieurs systèmes insulaires, ce phénomène n’a jamais été clairement identifié en Nouvelle-Calédonie, pourtant connue pour la richesse et l’originalité de sa flore. Par une approche combinant ar...
Thesis
Full-text available
Convergent evolution in growth habit is a fundamental phenomenon linking plant ecology and evolution. Remarkably illustrated in island biotas, this phenomenon has not clearly been identified in the distinctive and megadiverse New Caledonian biodiversity hotspot. Through an approach combining plant architecture, functional traits, taxonomy, phylogen...
Article
A new species of Euphorbiaceae, Bocquillonia corneri, narrowly endemic to the extreme north-east of New Caledonia’s main island, is here highlighted, described and illustrated, based on original morphological and architectural characteristics. This new species differs notably by its unique monocaulous tree habit, while other Bocquillonia species ar...

The Araliaceae family is well represented in New Caledonia, where ca. 75 species occur with a great diversity of foliar types across genera (simple in Meryta, palmate in Plerandra, pinnate in Polyscias). How does leaf type affect the balance between leaf traits related to support and light interception? We conducted a comparative study on 270 leave...
Article
Background: Lianas are an abundantand dynamic component of tropical forests, and their abundance ispredicted to increase with global change. A better understandingof factors that explain their distribution is required, especially onoceanic islands for which few data are available. Aims: Identifythe environmental factors that shape liana communities...
