Worldwide Genotyping in the Planktonic Foraminifer Globoconella inflata: Implications for Life History and Paleoceanography

R Morard, F Quillevere, CJ Douady, C de Vargas… - PLoS …, 2011 - journals.plos.org
The planktonic foraminiferal morpho-species Globoconella inflata is widely used as a
stratigraphic and paleoceanographic index. While G. inflata was until now regarded as a
single species, we show that it rather constitutes a complex of two pseudo-cryptic species.
Our study is based on SSU and ITS rDNA sequence analyses and genotyping of 497
individuals collected at 49 oceanic stations covering the worldwide range of the morpho-
species. Phylogenetic analyses unveil the presence of two divergent genotypes. Type I …
