TL;DR: Diversity emerged at all taxonomic levels, both within the groups comprising the ~11,200 cataloged morphospecies of eukaryotic plankton and among twice as many other deep-branching lineages of unappreciated importance in plankton ecology studies.

TL;DR: A comprehensive model for the Holocene peopling events of Chukotka and North America is developed, and it is shown that Na-Dene-speaking peoples, people of the Aleutian Islands, and Yup’ik and Inuit across the Arctic region all share ancestry from a single Palaeo-Eskimo-related Siberian source.
Journal ArticleDOI
Extreme Diversity of Diplonemid Eukaryotes in the Ocean

TL;DR: The results suggest that the planktonic diplonemids are among the key heterotrophic players in the largest ecosystem of the authors' biosphere, yet their roles in this ecosystem remain unknown.

TL;DR: A high-quality genome for Leptomonas pyrrhocoris, which is closely related to the dixenous genus Leishmania, is presented and several additional proteins potentially involved in virulence are identified, including SpoU methylase and U3 small nucleolar ribonucleoprotein IMP3.
Journal ArticleDOI
Evolution of metabolic capabilities and molecular features of diplonemids, kinetoplastids, and euglenids

TL;DR: A comparative genomic analysis across euglenozoan diversity finds a gradual loss of genes encoding enzymes in the evolution of kinetoplastids, rather than a sudden decrease in metabolic capabilities corresponding to the origin of parasitism, while diplonemids and eugLenids maintain more metabolic versatility.
