L’écologie de la restauration en France. Dynamique actuelle et rôle d’un réseau multi-acteurs, REVER
In the past few decades, ecological restoration and restoration ecology have widely developed. This trend can be explained by a rather favourable context, in particular legally speaking and regulatory framework-wise both at the European and nation-wide levels. Rediscovering the mitigation hierarchy "Avoid, Minimize, Restore" (ERC – Éviter, Réduire, Compenser) written in the 1976 French law, and implementing the E.U. habitats directives or the E.U. water framework directive and various nation-wide or local incentive policies or programs set up between 1990 and 2000, led to the development of restoration practice and research. Restoration or rehabilitation projects are nevertheless also confronted with administrative, socio-economic or technical obligations that can become real brakes.
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.
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”.
Areolar structure in some Opuntioideae: occurrence of mucilage cells in the leaf-glochid transition forms in Opuntia microdasys (Lhem.) Pfeiff.
Adansonia 38 (2)
One of the most remarkable features of Cactaceae are the areoles, axillary outgrowths, which produce trichomes, spines and leaves. The subfamily Opuntioideae K. Schum. shows the widest diversity of transition forms between leaves and spines, which represents anatomical evidence that spines and glochids are modified leaves. The purpose of this paper is to provide an anatomical description of the areolar structure in four species of Opuntioideae, in order that new anatomical homology between spines/glochids and leaves may be clarified. Different patterns of areole morphology are observed: 1) Austrocylindropuntia subulata (Muehl.) Backeb. showing terete and persistent leaves; areoles with persistent spines, glochids and trichomes; 2) Opuntia monacantha (Willd.) Haw.
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.
