Two recent publications from the PhD student, Déborah Henriques (University of Azores) on functional trait diversity along an elevational gradient and the presentation of the BRYOTRAIT-AZO, the first open access bryophyte database for traits. We wish to provide similar databases for the other studied archipelagos from the MOVECLIM project (Net Biome).

Bryophytes of Kenya's coastal forests - A guide to common species
Authors : Wilding N., Hedderson T., Ah-Peng C & Malombe I.
Date: dec. 2016
This guide was produced in the framework of the Kenyan Coastal forest project funded by the Indian Ocean Commission (FED/20015/358-516-SVC-101). This field guide presents 20 species of bryophytes (12 mosses and 8 liverworts) commonly encountered in Kenya's coastal forest region. Each species is accompanied by high quality images and easy to understand descriptions. A glossary of terms is provided as well as further reading and references on African bryophytes. Lire la suite
New article published in Basic & Applied Ecology :
Invasive natural enemies are known to either strengthen or weaken the suppression of herbivorous arthropods. However, the impact of invasive species on the predation service provided by natural enemy diversity remains largely unexplored. Here, we tease apart the roles of invasive ants as providers of a predation service and a potential disservice, i.e. reducing the diversity of natural enemies. In mango orchards on Reunion Island, we evaluated the predation service in 20 open fields by simultaneously monitoring the predation on bait eggs and arthropod communities in two strata: the ground surface and the mango tree canopy.

Didymodon vulcanicus is newly described and illustrated by Jimenez, Hedderson & Müller in the Journal of Bryology.
The type specimen was collected by Terry Hedderson (University of Cape Town) in Piton Marmite (Salazie).

E. Baumann is a Master'student (M2) from the University Of Bayreuth supervised by Pr. Carl Beierkunhlein and visiting the island to acheive the fieldwork of her project. She describes her experience.
On the 10th of August I arrived on the Island of La Reunion to conduct the fieldwork for my Master Thesis, which is embedded in the ECOPOTENTIAL project (H2020). The study aims at detecting patterns in leaf coloration along an elevational gradient in the subalpine shrublands of La Réunion island.
Beyond that aim, stands the concept that the elevational gradient is considered as a proxy for changing environmental conditions, as e.g. increased UV-radiation and increased wind speeds.

Once established, second-growth forests dominated by alien plants may provide suitable environmental conditions for the maintenance of populations of some rare native species, and thus should not be neglected in conservation studies.

We illustrate the case of Gastrodia similis Bosser, a small terrestrial orchid endemic to the lowland rainforest of Reunion island. Despite some very specific ecological requirements (necessary mycorrhizal symbiosis with wood-decay fungi and pollination by specialized drosophilid flies), the populations of this rare species are spreading beneath some secondary forests growing at low altitude, extending northward the species geographical distribution. Other native species might also restore populations in this place. We call for more biodiversity assessments and experimental trials in these hybrid ecosystems.
