Investigation of biogeochemical activities in the soil and unsaturated zone of weathered granite Inra
Legout, C.; Molenat, J.; Lefèbvre, S.; Marmonier, P.; Aquilina, L..
This study, based on field and laboratory work, investigates the biogeochemical activity below the organic top soil horizons, particularly the potential for nitrate removal processes in the deep vadose zone (1–2.5 m depth) of a weathered granite. An experimental site located in the Kerbernez agricultural catchment (Brittany) has been equipped with ceramic cups from 0.5 to 2.5 m depth since November 2001. This arrangement allowed collection of water samples from the soil profile and the upper part of the unsaturated weathered granite. Samples were analysed twice a month for chloride, nitrate and sulphate concentrations over a period of 2.5 years. Laboratory measurements were carried out on three soil horizons and four weathered granite facies sampled in...

On <i>Klieopsis</i> n. gen., with a description of <i>Cypridopsis horai</i> Klie, 1927 (Crustacea, Ostracoda) OMA
Martens, K.; Meisch, C.; Marmonier, P..
<i>Klieopsis</i> n. gen. is here described to comprise the species <i>Cypridopsis horai</i> Klie, reported from India. The new genus is characterized by an aberrant inner list on the RV, by a furca with a cylindrical trunk and by the reduction of two claws (G2 and Gm) on the A2 to short setae. After re-examination of the type materials, <i>Cypridopsis caerulescens</i> Klie from Kenya is synonymized with <i>K. horai</i>, which is here furthermore reported for the first time from Israel (surroundings of the Dead Sea). The latter specimens are extensively described, and a discussion on the taxonomic position of the new genus is offered. An apparently similar species from Sardegna, <i>Cypridopsis...
