Ariane Cosiaux, our international volunteer based in Yaoundé, has been Red Listing all African palms this last year. Today, her first article was published in the Biodiversity Data Journal under its new Species Conservation Profile section. We published the IUCN conservation assessment of Eremospatha dransfieldii, a rattan species growing in West Africa (Ghana and Ivory Coast). This species was assessed as "EN" meaning endangered, the second highest threat level, just after CR or critically endangered. Data gathered around this species (including its distribution, field observations and ongoing and future threats) suggests that its future will be in peril if nothing is done to stop deforestation and agriculture extension in the areas where it grows. Recently a total of 8 African rattan species were also included on the official IUCN Red List, one of them even being CR. Soon, the rest of the African palm species will be published too.
Red Listing is a central part of biodiversity conservation as this list is the only authoritative list governments, companies and project funders turn too when taking decisions about the impact a project has on biodiversity. As one one the co authors of this recent paper said: A species doesn't exist unless it has a conservation status (Lauren Gardiner).

We had our last RAINBIO meeting from 5th-9th December 2016 in Aix-en-Provence. RAINBIO started back in 2013 (funded by the CESAB call of the FRB) with the aim of synthesizing plant distribution data from tropical Africa. The RAINBIO publications is now available and open access here and the database is available here.
Several articles are in the pipe line, including a new R package that undertakes batch preliminary IUCN conservation assessments. More details will be available soon. We are now in the process of looking for extra funding to continue RAINBIO (2.0) and generate an online African distribution data platform.

On Thursday 24th of November 2016, Foulques Couvreur (FLS Production) and I organized an "avant première" of the award winning short documentary "Raphia: tree of life" (follow link for full movie) under my scientific supervision. This documentary and event is one of the outputs of the RAPHIA project. The event was attended by over 100 people (family, friends and colleagues), at the Vendôme cinema in Brussels. An excellent Q&A session followed the projection during which the public got acquainted with the RAPHIA project, Raphia palms, Africa and the technical difficulties of droning!
This movie is complementary to a second documentary that is due early december 2016 ("à l'échelle du Raphia"; "on Raphia and Man" (29 mins, directed by Joseph Fumtim & Thomas Couvreur, IRD).

Made a short video on the AFRODYN project. Images taken from several field trips during the project. Drone images from FLS production.

On Saturday 12th of November 2016, we travelled to the wonderful region of Oku (North West Cameroon) to project "à l'échelle du Raphia" ("On Raphia and Man"). The documentary relates the importance of the African Raphia palms and follows a team of researchers investigating the biodiversity, uses and economic importance of its species across Cameroon. We were accompanied by Philippe Le Gall (Entomologist, IRD), Joseph Fumtim (co producer, IRD), Suzanne Mogue (PhD Student, Université de Yaoundé 1) and Ariane Cosiaux (International Volunteer, IRD).
We were received by the Fon (king) of Oku, His Majesty Senteih II and the prince Shey Wilfred Mbunda as well as numerous other notables of the region.
The official version of the documentary will be available by end November.
​This project was funded by IRD and Agropolis International as part of the RAPHIA project.

Our article detailing the RAINBIO mega dataset is out!
With this article we publish one of the largest datasets of tropical African plant distributions to date. It contains over 600k unique georeferenced plant occurrences for over 22k plant species. Manual and automatic specimen checking was undertaken by the RAINBIO consortium. This article is published within the framework of the RAINBIO project, funded by FRB, CESAB calls.

Our new study focused on two central African understory palm species of the genus Podococcus. Using species distribution modeling in the past and the present combined with over 100 plastomes sequenced using NGS we found a strong correlation between climatically stable areas for the species and high unique genetic diversity.

Congrats to Adama for his third PhD article!

In June 2016 I went to the Monts de Cristal National Park in Gabon (as part of the AFRODYN project), basically to the same area where Hervé Sauquet and myself discovered Sirdavidia solannona back in 2012. I was walking around trying to find more individuals and populations of Sirdavidia and checking to see if it was flowering (which it was not...). After a while my Gabonese colleague, Raoul Niangadouma, and myself fell upon a medium sized tree with small flowers at the base. The species looked like an Uvariopsis, but it was "weird" looking. The flower buds were sessil and incredibly the crushed flowers and leaves emitted a strong scent of lemon. The leaves were very large for the genus too. To date, there has been no repports of lemon scent in Uvariopsis, and only a single species has sessile flowers (U. sessiliflora), and this was not that! The only other lemon scented species I know of in African Annonaceae is also from Gabon, and is Uvariodendron molundense var. citrata (Le Thomas 1969, Flore du Gabon).

At that point we knew we had a new species of Uvariopsis. It was hard to think that yet again in this same area we stumbled upon yet another new species of Annonaceae (just 100 m from the type locality of Sirdavidia), even though we were quite close to Kinguélé village and the main road! No sooner did we get back to our camp, we started to write up the article (see photo below). The idea was to show that we should not wait too much before describing and publishing new names. In our case it took less than two months between collection of the type and publication in PhytoKeys. Sure, we didn't spend all day in different herbaria going through all the material available, however, I was sure it was new and there were no names associated with this species yet. Do you agree?

The new species is called Uvariopsis citrata Couvreur & Niangadouma. The area where we collected these new species deserves an increased protection and more botanists should wander around there given its easy access and potential for new discoveries.

Amira successfully defended her Master I (Université de Montpellier II) project on Annonaceae floral evolution! In the top three of her class!
