Suivis nationaux de biodiversité en forêt en France : une lecture au travers des Variables Essentielles de Biodiversité
Based on a national review, we analysed twelve forest and biodiversity monitoring networks in metropolitan France using the conceptual framework of the Essential Biodiversity Variables (EBV). Quite evidently, sampling strategies adopted by each network correspond to its aims and objectives. The national forest inventory is the only network analysed representative of French forests. A given network often covers only one taxon (notably tree and shrub species) and more marginally other taxonomic groups (including lichens, soil micro and macrofauna). The EBV analysis reveals that genetic diversity is the less covered component. The other biodiversity components are better represented, notably community-scale components and to a lesser extent, species traits.
Judith Najt. A life dedicated to Collembola and research support for systematics
Zoosystema 39 (1)
Judith Najt was born in Argentina on 9th January 1937, and passed away there on 10th December 2014, after spending most of her life in France. During the last decades she made an important mark on collembology as well as on Entomology at the Muséum national d’Histoire naturelle (MNHN), being at the origin of the largest research team currently working on biodiversity in France.
The anatomy and phylogenetic affinities of Cynthiacetus peruvianus, a large Dorudon-like basilosaurid (Cetacea, Mammalia) from the late Eocene of Peru
Geodiversitas 39 (1)
Cynthiacetus peruvianus Martínez-Cáceres & Muizon, 2011 is a Dorudon-like basilosaurid (Cetacea, Basilosauridae), being one of the largest members of the family. The holotype of this species is a sub-complete skeleton, which comes from the late Eocene (Priabonian) of the Otuma Formation on the southern coast of Peru. A thorough description of this specimen is presented here. Cynthiacetus peruvianus differs from the other species of the genus (C. maxwelli) in having fewer accessory cusps on the distal and mesial edges of p3 and p4.
La Réserve biologique intégrale du Mont-Ventoux, un espace d’étude des écosystèmes forestiers hors sylviculture
The Wilderness Area of Mount Ventoux, established in 2010, is an ideal study site owing to its variety of environments, at the crossroads of alpine and mediterranean influences. For this reason, the French National Forestry Office has planned and implemented an investigation agenda focusing on four fields: forest stands, birds, saproxylic beetles and fungal species. The analysis of the forest stands inventory has highlighted the richness of this reserve regarding forest structures: very old stands (up to four centuries old for the oldest), more recent stands from reforestation, and open areas are closely intermingled. This mosaic of various situations explains the ecological interest of the reserve in terms of both rarity and diversity of the observed species.
Toward the DNA Library of Life
European Journal of Taxonomy 2017
The special set of papers entitled “DNA Library of Life” constitutes an outcome of the project “Bibliothèque du vivant” (BdV), which aims to promote the molecular taxonomy of eukaryotes by offering research teams the possibility to produce and manage a molecular library linked to specimens deposited in natural history museums. The project was funded by three French institutions (the CNRS, INRA and MNHN), and provided access to the sequencing power of the Genoscope for 105 teams between 2011 and 2013. It was subsequently supported by the CNRS through the “Groupement de Recherche Génomique Environnementale”.
Le morse et le phoque dans les mers du Nord au Moyen Âge : chasse, exploitation, commerce. Une approche par les textes
Anthropozoologica 51 (2)
The sources we have tend to prove that, during the Middle Ages, men fear the sea and the creatures living in it. The walrus, subject of a terminological ambiguity, is no exception to the rule. However, both the walrus and the seal are hunted, for hunters have a more realistic view of these animals. Mainly based on Norse texts, and in particular on Icelandic sagas, this article intends to identify the main features of the hunting of these amphibian mammals in northern seas. While hunting is vital in some areas, it is subject to very restricting rules elsewhere, which can sometimes lead to conflicts. As a matter of fact, northern seas have seen trade become increasingly dynamic during the Middle Ages, in which the walrus and its precious ivory tusks have their place.
