Three new species of lemurs in Madagascar

08.03.2006


An international team, composed of Malagasy and European researchers, has just discovered three new species of lemurs, small primates endemic to Madagascar.

The work carried out by this international team has enabled the identification of three new species of lemur based on the characteristics of their mitochondrial DNA : Lepilemur randrianasoli, L. aeeclis and L. sahamalazensis. They were discovered in the West and North West of Madagascar, bringing the number of species of lemur up to 11. This number probably underestimates the diversity of the Lepilemur genus, with other species no doubt waiting to be discovered in other parts of the island.

Lemurs are small, nocturnal, primates native to Madagascar, weighing around 800g. They belong to an endemic genus subject to great pressure by Man either by hunting or by deforestation, where the systematic is still much debated. Primates are divided into two suborders : Prosimians (Lemuroidea) and Simians, the latter comprising both monkeys and humans. Lemurs are classed as Prosimians.


Jointly supported by the University Louis Pasteur (ULP) and by the European Association for the Study and Conservation of Lemurs (A.E.E.C.L.), four Malagasy researchers from the University of Antananarivo have been working in collaboration with several European groups and with two laboratories in particular: the ULP research unit EA3428 "Espèce humaine et primates : variabilité et évolution" (Director Bertrand Ludes) and the "Deutsches Primatenzentrum" in Göttingen. By performing chromosomal and molecular biological studies, these researchers have determined the complete DNA sequence of a mitochondrial protein (cytochrome b), from 68 specimens from 21 different geographical locations. These results were compared to the preliminary chromosomal studies conducted on 99 known specimens. This helped establish a phylogenetic comparison between the species analysed in the current tests and those performed previously, enabling the researchers to define the classification of these lemurs.

The results obtained in this exemplary cooperation are of great importance to the understanding of the diversity and evolution of the Lepilemur genus in Madagascar, and form a solid base for future research programmes concerning the Malagasy fauna and its conservation.

Im Focus: Powerful IT security for the car of the future – research alliance develops new approaches

The more electronics steer, accelerate and brake cars, the more important it is to protect them against cyber-attacks. That is why 15 partners from industry and academia will work together over the next three years on new approaches to IT security in self-driving cars. The joint project goes by the name Security For Connected, Autonomous Cars (SecForCARs) and has funding of €7.2 million from the German Federal Ministry of Education and Research. Infineon is leading the project.

Vehicles already offer diverse communication interfaces and more and more automated functions, such as distance and lane-keeping assist systems. At the same...

Im Focus: Molecular switch will facilitate the development of pioneering electro-optical devices

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.

The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...

Im Focus: LZH showcases laser material processing of tomorrow at the LASYS 2018

At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...

Im Focus: Self-illuminating pixels for a new display generation

There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?

At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
