Note sur quelques foraminifères du Strunien et du Dinantien d'Europe Occidentale
Description of new Dinantian Foraminifers: Earlandiidae, Tournayellidae, Endothyridae and Loeblichiidae. Emendations and corrections relating to Archaediscidae, Endothyridae and Tournayellidae
Stratigraphic interpretation of the Tohogne borehole (province de Luxembourg). Devonian - Carbinoferous transition
The Tohogne borehole section, from the Lower Tournaisian into the Upper Famennian, has a remarkable micropalaeontological content (conodonts, foraminifers, spores) which enabled a detailed subdivision of these strata. New data in biostratigraphy and systematic palaeontology and palaeogeographic implications are presented, as well as correlations with reference sections
Foramiminifères, spores et coraux du Famennien superieur et du Dinantien du Massif de l'Omolon (extreme-orient sovietique)
Faunal assemblages allowing biostratigraphical Upper Famennian and Dinantian correlations between the Omolon Massif and Western Europe were recorded by Simakov in 1979. New investigations in 1981 allowed to improve the correlations using forams, corals and also palynological material from one shaly sample
The Devono-Carboniferous transition in the Franco-Belgian basin with reference to Foraminifera and Brachiopods
After a brief summary of the most striking evolutionary trends of the Upper Frasnian through Lower Tournaisian foraminifer assemblages in Northwestern Europe, some new biostratigraphic data are discussed mainly from an important section near St. Hilaire (Avesnois area, Northern France) as well as their impact on the problem of the Devono-Carboniferous boundary in the Franco-Belgian Basin

Incorporating field wind data to improve crop evapotranspiration parameterization in heterogeneous regions
Accurate parameterization of reference evapotranspiration ( ET0) is necessary for optimizing irrigation scheduling and avoiding costs associated with over-irrigation (water expense, loss of water productivity, energy costs, and pollution) or with under-irrigation (crop stress and suboptimal yields or quality). ET0 is often estimated using the FAO-56 method with meteorological data gathered over a reference surface, usually short grass. However, the density of suitable ET0 stations is often low relative to the microclimatic variability of many arid and semi-arid regions, leading to a potentially inaccurate ET0 for irrigation scheduling. In this study, we investigated multiple ET0 products from six meteorological stations, a satellite ET0 product, and integration (merger) of two stations’ data in Southern California, USA. We evaluated ET0 against lysimetric ET observations from two lysimeter systems (weighing and volumetric) and two crops (wine grapes and Jerusalem artichoke) by calculating crop ET ( ETc) using crop coefficients for the lysimetric crops with the different ET0. ETc calculated with ET0 products that incorporated field-specific wind speed had closer agreement with lysimetric ET, with RMSE reduced by 36 and 45% for grape and Jerusalem artichoke, respectively, with on-field anemometer data compared to wind data from the nearest station. The results indicate the potential importance of on-site meteorological sensors for ET0 parameterization; particularly where microclimates are highly variable and/or irrigation water is expensive or scarce
