Abstract:

A composite Tethyan Late Jurassic-Harly Cretaceous carbon and oxygen isotope curve is presented. C-isotope data provide information on the evolution and perturbation of the global carbon cycle. O-isotope data are used as a palaeotemperature proxy in combination with palaeontological information. The resulting trends in climate and in palaeoecanography are compared with biocalcification trends and oceanographic conditions favouring or inhibiting biocalcification. Positive C-is...

	Stability of Carbon Isotope Discrimination and Grain Yield in Durum Wheat.(Statistical Data Included) Crop Science ; THE MEDITERRANEAN CLIMATE is characterized by low and highly variable annual rainfall (200-800 mm) and typically less than 100 d of rainfall, mostly concentrated during the winter (Baldy, 1986). Water deficit and high temperatures often occur during grain filling (Loss and Siddique, 1994), causing

	Carbon Isotope Discrimination as a Tool to Improve Water-Use Efficiency in Tomato. Crop Science ; PLANT BIOMASS production depends on the amount of water used for growth as well as on water-use efficiency, WUE.
