THE FRENCH NATIONAL SOIL QUALITY MONITORING NETWORK (RMQS) AS A SUPPORT FOR MONITORING SOIL BIODIVERSITY: past, present and future programs
2021
Soil biodiversity would represent about 25% of the species on Earth. It is threatened, and although it is essential for human activities, it remains largely unknown. The French National Soil Quality Monitoring Network (RMQS) has a significant impact in removing the grey areas through its programs on soil microorganisms, soil meso and macrofauna, meadow flora, truffles and more recently enzymatic activities. The first distribution maps of bacterial phyla on a national scale and of soil fauna on a regional scale (in Brittany) have been developed. For the white truffle, three new areas of presence have been identified in France. The habitats of the bacteria were also described for the first ti…
Eomyidae fauna turnover at the Early-Middle Miocene boundary in the Morteral section (Magro Basin, Valencia, Spain)
2012
Abstract The material of Eomyidae from three localities (Morteral 1, Morteral 20A and Morteral 22) of the Morteral section in the Magro Basin, eastern Spain, is described. These localities contain remains of Ligerimys and Eomyops. Morteral 1 is situated in the lowest part of the section and contains Ligerimys ellipticus, whereas Morteral 20A and Morteral 22 are situated in the middle part of the section and contain, among other rodent species, Eomyops noeliae. The youngest localities in the Morteral section (Morteral 41 and 44) record Megacricetodon collongensis, first representative of Megacricetodon in the Middle Miocene (MN5). The locality Morteral 20A contains Megacricetodon primitivus;…
New records of phytoseiid mites from Italy, with description of a new species and a redescription of other two (Parasitiformes, Phytoseiidae)
2020
The Italian phytoseiid fauna consists of 91 valid species. Eighteen of them were described as new species from materials collected in various Italian localities. In the present paper we report nine new records from the Italian fauna and describe the new species, Neoseiulus mediterraneus belonging to the subfamily Amblyseiinae. Complementary descriptions of two rare species, namely: Typhlodromus (Anthoseius) singularis and Typhlodromus (Typhlodromus) knisleyi, were also added.
Gastrointestinal helminths of Risso's dolphin Grampus griseus from the Western Mediterranean.
2003
The gastrointestinal helminth fauna of 17 Risso's dolphins Grampus griseus (Cuvier, 1812) from the Western Mediterranean was analysed. Five helminth species were found. Adults and juveniles of Hadwenius delamurei were collected from the duodenum of 7 animals. Adults were located significantly more anteriorly than juveniles, which is compatible with a previous hypothesis that species of Hadwe- nius undergo an ontogenetic migration towards the anterior duodenum. Eggs from Pholeter gastrophilus appeared in 1 small cyst in the main stomach. Adults of Tetrabothrius forsteri and Trigonocotyle globicephalae were collected from the duodenum of 1 and 4 individuals, respectively. Metaces- todes, Scol…
La Crisis de salinidad messiniense: el papel de los microfósiles durante 60 años de estudio
2021
Para comprender fenómenos geológicos extremos, como la llamada Crisis de Salinidad del Messiniense (CSM), es necesario estudiarlos de forma multidisciplinar y a diferentes escalas. Para ello, se realizan desde estudios geofísicos del subsuelo, que abarcan grandes extensiones del fondo del mar, hasta estudios micropaleontológicos, utilizando microscopio electrónico de barrido. Los restos de organismos que vivieron ese evento geológico aportan una información muy valiosa para comprender la paleogeografía y el paleoambiente durante el Messiniense. Con ese objetivo, los paleontólogos y palinólogos estudian bajo el microscopio fósiles de fauna marina y continental, así como restos de flora en fo…

Marine caves of the Southern Tyrrhenian Sea: a First Census of Benthic Biodiversity
2017
This is the first paper documenting research on a selection of marine caves located along the coast of Capo Milazzo in the southern Tyrrhenian Sea. Three submarine and one semi-submerged caves were surveyed and sampled using underwater photo sampling. Surveys have only taken into account the sessile species belonging to the main taxa: Porifera, Anthozoa, Bryozoa and Polychaeta. Diversity indices and abundances were calculated for three sections within each explored cave: the Entrance Zone, Intermediate Zone and Bottom Zone. The richest group was Porifera with 21 taxa, followed by cnidarians, (Anthozoa), with 8 taxa, Polychaeta (5 taxa), and Bryozoa (5 taxa). Among Porifera, the presence of …
Pleistocene allopatric differentiation followed by recent range expansion explains the distribution and molecular diversity of two congeneric crustac…
2021
AbstractPleistocene glaciations had a tremendous impact on the biota across the Palaearctic, resulting in strong phylogeographic signals of range contraction and rapid postglacial recolonization of the deglaciated areas. Here, we explore the diversity patterns and history of two sibling species of passively dispersing taxa typical of temporary ponds, fairy shrimps (Anostraca). We combine mitochondrial (COI) and nuclear (ITS2 and 18S) markers to conduct a range-wide phylogeographic study including 56 populations of Branchinecta ferox and Branchinecta orientalis in the Palaearctic. Specifically, we investigate whether their largely overlapping ranges in Europe resulted from allopatric differe…
