Atlantic origin of the arctic biota? Evidence from phylogenetic and biogeographical analysis of the cheilostome bryozoan genus pseudoflustra.
The intricate geological evolution of the Arctic Ocean is paralleled by complexities in the biogeographical and phylogenetical histories of the Arctic biota, including bryozoans. Here we present revised taxonomic descriptions for all known species of the bryozoan genus Pseudoflustra, and use the pre...
