Xper2 is a knowledge data bases system. Xper2 and its associated tools is a plate-form dedicated to taxonomic descriptions and computer-aided-identification. It requires no special computer skills. It is very easy to use for the amateur naturalist that wants to identify a specimen with an already made application, as well as for the professional taxonomist that creates new applications. It is developped by the lab LIS , a bioinformatic component of the Institut de Systématique Evolution Biodiversité at the MNHN.

Xper2 is the local version, on your computer.

Xper3 is the online version.

After one week spent at the Herbarium of TAN, we left for Andasibe, 120 km East from Antananarivo, in order to enhance the knowledge on bryophytes diversity by new collection.

Our cars are loaded in front of our GuestHouse Tanajacaranda.

During the workshop, students are trained to bryophytes diversity: the different groups of bryophytes, how to recognized them, how to manage bryophyte collection etc. Each researcher participates to the training, depending of their own observations, and on the students questions.

Here, Roger Lala Andriamiarisoa (standing at the door) and Catherine Reeb on his right are showing how to use an identification key to identify mosses.
