Neotropical ostracode oxygen and carbon isotope signatures: implications for calcification conditions.

ABSTRACT: Calcitic valves of non-marine ostracodes are important geochemical archives. Investigations of the relationship between the ranges of oxygen and carbon isotope values of modern ostracode populations and their host water provide important information on local or regional conditions and influences. Here we present the first δ¹⁸O_ostracode and δ¹³C of the freshwater ostracode species Cytheridella ilosvayi along with the isotopic composition of the waters in which the ostracodes calcified, δD_water, δ¹⁸O_water, δ¹³C_DIC values-covering a large geographical range (Florida to Brazil). With this data we extended a newly developed approach based on the estimation of δ¹⁸O values of monthly equilibr
