Annual Partitioning Patterns of Labyrinthulomycetes Protists Reveal Their Multifaceted Role in Marine Microbial Food Webs

Applied and Environmental Microbiology, 2020
Increasing evidence has shown that heterotrophic microeukaryotes are an important component in global marine ecosystems, while their diversity and ecological functions remain largely unknown.

Maximizing eDNA detections of rare marine organisms: A case study of a delphinid species

Methods in Ecology and Evolution, EarlyView.
Abstract Environmental DNA (eDNA) is an emerging tool for surveying marine organisms. Advances in molecular assay designs and bioinformatic methods provide new opportunities for detecting rare species; however, overcoming methodological challenges of rare species detection remains an important obstacle for the widespread deployment of eDNA methods for ...

Tracing the Origin of Planktonic Protists in an Ancient Lake

Microorganisms, 2020
Ancient lakes are among the most interesting models for evolution studies because their biodiversity is the result of a complex combination of migration and speciation.

Optimizing a long‐term monitoring strategy to track emerging cyanobacterial blooms in a Great Lakes estuary

Journal of Phycology, EarlyView.
Abstract Cyanobacterial harmful algal blooms (cHABs) are increasingly frequent and severe globally. Recently, the St. Louis River Estuary (SLRE) has experienced numerous cHABs, but the locations, timing, and environmental conditions associated with them are unknown.

Marine Viruses: Key Players in Marine Ecosystems

Viruses, 2017
Viruses were recognized as the causative agents of fish diseases, such as infectious pancreatic necrosis and Oregon sockeye disease, in the early 1960s [1], and have since been shown to be responsible for diseases in all marine life from bacteria to ...

Linking variation in genome size to cyst size in chrysophytes

Journal of Phycology, EarlyView.
Abstract Genome size varies tremendously across eukaryotes, which often contain far more DNA than expected from their biological complexity. To explain this paradox, selection‐based hypotheses propose that genome size evolves through selection acting on life‐history traits correlated with the phenotypic effects, independent of its genic content.

Advanced approach to analyzing calcareous protists for present and past pelagic ecology: Comprehensive analysis of 3D-morphology, stable isotopes, and genes of planktic foraminifers.

PLoS ONE, 2019
Marine protists play an important role in oceanic ecosystems and biogeochemical cycles. However, the difficulties in culturing pelagic protists indicate that their ecology and behavior remain poorly understood; phylogeographic studies based on single ...

Proteins Associated with Salinity Adaptation of the Dinoflagellates: Diversity and Potential Involvement in Species Evolution

Diversity
Protists inhabit marine, brackish and fresh waters. The salt barrier plays an important role in the origin of their diversity. Salinity tolerance differs among species and sometimes even among different strains of the same species, indicating local ...

Persistent mirusvirus infection in the marine protist Aurantiochytrium

Nature Communications
Mirusviruses are abundant and broadly distributed double-stranded (ds) DNA viruses recently discovered in marine metagenomic data. Their host range and ecological impact are unclear. The protist Aurantiochytrium limacinum possesses two mirusvirus-like genomic elements, one a circular episome (AurliV-1) and the other (AurliV-2) a chromosomal integrant ...
