What is Xper2 ?

The team discovering Xper2 interface, in TAN herbarium. Very concentrated !
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.
The Madbryo Project, through Bryotan workshop and production aims to synthetize taxonomic data on Malagasy bryophytes on Xper2 systems. Small Xper2 databasis, for example on Polytrichaceae, Bazzania etc. are in progress. Species list and their standardized descriptions, with comment, illustration of species, of characters and characters sates. They allow ideintifications.
You may have a look to online examples o identifications guided by Xper system.

This choice may be explained by many reasons:
  1. Standardization of description , caharcters and characters sate for a whole taxon
  2. Modification are very easy (adding a new character or character state, species is very easy and do not require to change all the database. All tools are automatically updates)
  3. Identification can be conducted from any character (no dichotomous keys)
  4. Xper3, the online version, is very firendly and allows on line identifications

Digitazing and data cleaning

By BRYOTAN • 04 Feb, 2019
At the date of February 2nd, 2019, 2427 occurences were digitalized by Fara (here at her desk), but also by Eliane and by Miarisoa , helped by ELlysée and Rita during the workshop. We hope to reach more than 3000 occurences at the ned of Februrary 2019.

Bryophytes on the field day 1

By Catherine Reeb • 03 Oct, 2018
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.

Bryophytes treatment during the workshop

By Bryotan team • 27 Sep, 2018
Enveloppes with unidentified specimens or with specimen with a pre-identification, usually given on the field are sorted out from the herbarium, up to the working room.

Like a swirling hive among bryophytes

By Catherine Reeb • 26 Sep, 2018
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.

On the image at the top, sitting at the table, from left to right : Miarisoa (Antananarivo), Roita (Mahajanga), ElLiane (Antananarivo) and Elysée (Mahajanga).

The workshop began !

By BryotanTeam • 24 Sep, 2018
A part of our team, from left to right, Eberhard Fischer (Germany), Nick Hodgets (UK), Anrea Sass (Hungaria) inaugurate our working room. A part of microscopes and lens were borrowed from Tana University, thanks to the department of Biologie Végétale.
During this firts day, we just finished to install the room, we tested the organisation and began our first observation.
