JoeriResearch profile:

Following a 3-year postdoctoral Fellowship (2011-2014) at the Xishuangbanna Tropical Botanical Garden (Chinese Academy of Sciences), I am now working as an associate professor at the Plant-Ecophysiology & Evolution group of the College of Forestry, Guangxi University, Nanning.

Biodiversity Genomics Team

In the Biodiversity Genomics Team we focus our research efforts on understanding the origin, rise and persistence of tropical plant biodiversity by combining the latest NextGen sequencing techniques and advances in genomics with molecular systematics, taxonomy, ecology and historical biogeographical reconstruction. Our study area covers the greater tropical Australasian zone and extends to include the flora of the Madagascar and Indian Ocean Island Biodiversity Hotspot.
Members of my team address a wide range of research topics, ranging from understanding the effects of palaeogeographic changes in landmass configuration on patterns of plant genome evolution and divergence, studying community assembly and in-situ plant diversification patterns on oceanic islands, to using genomic data to clarify the links between gene divergence, diversification and distribution, and employing the latest NGS techniques to resolve longstanding botanical and evolutionary questions typical for amorphic, speciose and widespread tropical tree families.

 

***Genomics, Diversification and Historical Biogeography of Tropical Asian Fagaceae***

Tropical Fagaceae in Asia occur from the foothills of the Himalayas, to the southern islands of Japan and eastward to Papua New Guinea and the Louisiade Archipelago. With over 600 species, in four genera, Fagaceae form an integral component of the tropical forests of Asia. Species can be found at all elevations, including the lowlands, but diversity is maximized at medium to high elevation zones, where Fagaceae dominate the forest system, or co-dominate, together with Lauraceae, Theaceae, Magnoliaceae and other families in a range of ecosystem conditions known as Laurisilva or Laurel forest. This set of environmental conditions spreads beyond the geographical distribution of tropical Asian Fagaceae, with Fagaceae being replaced by other plant families. In Australia and further south for example, Fagaceae are not present, but an ecologically similar forest type prevails dominated by Nothofagaceae, Myrtaceae, Winteraceae, Podocarpaceae and others.

My research on tropical Asian Fagaceae encompasses molecular systematics, molecular dating and historical biogeographical reconstruction. To this end, I use a combination of traditional Sanger sequencing and genomic sequencing techniques, in order to construct molecular datasets for selected regions of the chloroplast and nuclear genome. Together with collaborators, we develop new molecular markers from genomic data and move towards true comparative genomics in this large and ecologically important plant family. Molecular and morphological datasets are used in phylogenetic analyses to reconstruct the evolutionary history of tropical Asian Fagaceae, to assess lineage accumulation, progression of evolutionary rates over time and to evaluate the role of potential historical/environmental triggers in diversification of the family. Plant collecting missions, performed across the region in close collaboration with local institutes, are fueling additional projects leading to taxonomic revisionary work, evolutionary analyses of plant functional traits and the construction of interactive online keys for Lithocarpus, Castanopsis and Quercus. For more information of tropical Asian Fagaceae and my work on this family, visit http://www.asianfagaceae.com/.

 

***Plant diversification in the Madagascar and Indian Ocean Islands Biodiversity Hotspot***

Following work conducted as a Marie Curie PhD Fellow at the Laboratoire Evolution et Diversité Biologique (University of Toulouse, France), I continue to be involved in and develop studies on phylogeography, community assembly and diversification of plant lineages in the Madagascar and Indian Ocean Island biodiversity hotspot. Families with selected genera in past and current studies include Primulaceae, Monimiaceae, Asteraceae, Myrtaceae, Ebenaceae, Sapindaceae, Rubiaceae, Urticaceae and Rutaceae.


 

***Flora of Cambodia, Laos and Vietnam – Fagaceae***

It has been over nearly seventy years since a thorough treatment on Fagaceae of the Indochina region has been published. Since Lecomtes’ Flore Generale de l’Indochine and the monographs by Camus, many new species have been discovered, described and major changes have taken place in the family. In addition, groundbreaking advances in species identification, phylogenetic inference and biogeographic reconstruction using DNA have been made. With support from the Muséum National d’Histoire Naturelle (MNHN) in Paris (http://www.mnhn.fr/), the Royal Botanical Gardens (RBGE) in Edinburgh (http://www.rbge.org.uk) and local partner institutes and specialists in Vietnam, Cambodia and Laos, the project will see the creation of a new flora for the region on a major plant family. These efforts are strongly supported by ongoing molecular programs on Asian Fagaceae funded by Guangxi University, Nanning, China.

***Other projects***

Together with groups of researchers from the Ecological Evolution Laboratory (led by Dr. Yann Surget-Groba) and Community Ecology & Conservation Group (led by Dr. Kyle Tomlinson) of the Xishuangbanna Tropical Botanical Garden (Chinese Academy of Sciences) I am also involved in projects on the evolution and ecological significance of spinescence in plants, genomic adaptations to environmental gradients in tropical trees, adaptive vs. plastic responses across trophic levels by natural populations to environmental gradients and evolutionary analyses of plant functional traits in mangroves (latter project in this lab, led by Prof. Cao Kunfang more information here).

In addition, through other collaborations, I am taking part in studies on diversification of Dipterocarpaceae, Mallotus and Macaranga (Euphorbiaceae), Duguetia (Annonaceae) and Diospyros (Ebenaceae).

The extensive geographic distribution of Asian Fagaceae, their high diversity and the habitat in which we find them, combine to make the sampling and study of tropical Fagaceae an exceptional challenging activity. I am always interested to explore opportunities to work with new collaborators and expand the species number and geographic regions currently under study.
