Until recently, the evolutionary relationships between marine and freshwater microbes were
unclear, but the use of molecular phylogenies is beginning to shed light on this subject. An …

Much of what we know about speciation comes from detailed studies of well‐known model
systems. Although there have been several important syntheses on speciation, few (if any) …

Eukaryotic microbes (protists) residing in the vertebrate gut influence host health and
disease, but their diversity and distribution in healthy hosts is poorly understood. Protists …

Marine protists have traditionally been assumed to be lowly diverse and cosmopolitan. Yet,
several recent studies have shown that many protist species actually consist of cryptic …

New data support our previously published propagule dispersal hypothesis and show that
propagules of some benthic foraminiferal species can survive for two years before growth …

Plankton ecologists ultimately focus on forecasting, both applied and environmental
outcomes. We review how appreciating planktonic ciliates has become central to these …

Taxonomy is the science of defining and naming groups of biological organisms based on
shared characteristics and, more recently, on evolutionary relationships. With the birth of …

Microbial eukaryotes hold a key role in aquatic ecosystem functioning. Yet, their diversity in
freshwater lakes, particularly in high‐mountain lakes, is relatively unknown compared with …

Recent advances in high-throughput sequencing and metabarcoding technologies are
revolutionizing our understanding of the diversity and ecology of microbial eukaryotes …

Taxa of microbial eukaryotes defined on morphological basis display a large degree of
genetic diversity, implying the existence of numerous cryptic species. However, it has been …
