Size Fraction Effects on Planktonic Foraminifera Assemblages: A Compositional Contribution to the Golden Sieve Rush
A comparative study of Last Glacial to Holocene planktonic foraminiferal assemblages obtained from 150 to 106 m size fractions of a Tyrrhenian sea core was carried out by means of compositional data analysis methods. The results show a major loss of small-sized species in the 150 m size fraction, re...
