Rodent pest management in multifactorial socio-ecosystems: a practical application to the Jura massif
For nearly a hundred years, a mass of attempts has been made to understand the causes of multi-annual fluctuations of rodents. Approaches that seek to isolate one factor among possibly dozens have all led to a long list of conclusions, all correct, about "what does not explain…". Approaches assuming multifactor explanations face the major difficult...
Confirmation of the validity of the genus Cretaceousbuthus Lourenço, 2022 and description of a new species from Burmite...
The study of new scorpion specimens from Cretaceous Burmite leads to the descriptions of a new species which once again can be associated to the buthoid lineage and to the family Buthidae. With this description the validity of the genus Cretaceousbuthus is confirmed. The new species shows quite distinct characters, particularly a telson with a coni...
Early Jurassic silicified woods from Carapace Nunatak, South Victoria Land, Antarctica
The Jurassic vegetation of Antarctica remains poorly known and, while there have been several reports of large fossil trees from that time period across the continent, detailed anatomical studies of their wood are extremely scarce. Here we describe new silicified woods of Early Jurassic (probably Toarcian) age from Carapace Nunatak, South Victoria ...
Quelques remarques sur le genre Xixuthrus Thomson, 1864 avec la description de deux nouvelles espèces (Coleoptera, Cera...
Les espèces Xixuthrus isyuniarkoi n. sp. et Xixuthrus tarkus n. sp. sont décrites respectivement de West Papua (Indonésie) et de l’île Umboi (Papouasie Nouvelle-Guinée). Le sous-genre Daemonarthra est mis en synonymie avec le genre Xixuthrus. L’espèce Xixuthrus costatus est attribuée à Waterhouse (1885) alors que le Mallodon costatus de Mon...
Bacterial Microbiota of Ostreobium, the Coral-Isolated Chlorophyte Ectosymbiont, at Contrasted Salinities
Microscopic filaments of the siphonous green algae Ostreobium (Ulvophyceae, Bryopsidales) colonize and dissolve the calcium carbonate skeletons of coral colonies in reefs of contrasted salinities. Here, we analyzed their bacterial community’s composition and plasticity in response to salinity. Multiple cultures of Pocillopora coral-isolated Ostreob...
Analysis of an intra-and interspecific interference model with allelopathic competition *
Understanding and exploiting competition and coexistence between microbial species is one of the more challenging aspects of mathematical biology. In this paper, we propose an original model of two-microbial species competing for a single nutrient in the chemostat including general intra-and interspecific density-dependent growth rates with allelop...
Impact of vessel noise on feeding behavior and growth of zooplanktonic species
Anthropogenic noise is a pervasive feature of the coastal ocean soundscape and is intensifying as vessel traffic activity increases. Low-frequency sounds from wave action on coastal reefs or anthropogenic noise have been shown to initiate larval settlement of marine invertebrates and accelerate metamorphosis to juvenile stages. These results sugges...
The French National Committee on Scientific Diving (CNPS): a key actor for developing scientific diving in France
...
The French National Committee for Scientific Diving (CNPS) is an inter-agency committee on scientific diving activities. French marine universities, research institutes (CNRS-INEE/INSU/INSHS, DRASSM, EPHE, IFREMER, INRA, INSERM, IPEV, IRD, IRSTEA) and the National Museum (MNHN) are involved or represented. The CNPS, created in 1999, is the scientif...
On Elaphidion tuberculicolle Fisher, 1932 and Elaphidion scaramuzzai Fisher, 1951 (Coleoptera, Cerambycidae)
The difference between Elaphidion tuberculicolle Fisher, 1932 and E. scaramuzzai Fisher, 1951 is reported, and the differences pointed out in the original description of the latter are commented on. The key to species of Elaphidiini from Cuba by Devesa et. al. (2015) is partially modified.
