Webb7 mars 2024 · To consider multiple factors–genetic, morphological, and geochemical traits–in marine protistan ecology, biomineral shell-bearing protists, like planktic foraminifers, are good study candidates. The calcareous shells of planktic foraminifers have already been used in morphological and isotopic analyses. WebbAlthough constituting more than 100,000 described species, protists are virtually ignored within the arena of biodiversity conservation. One reason is the widespread belief that the majority of protists have cosmopolitan distributions, in contrast to the highly hetereogenous biogeography of the “mega-Metazoa”. However, modern research reveals …
