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.

Comprehensive revision of Mallomonas sect. Peroneides stat. nov. (Chrysophyceae) integrating morphology and multigene phylogeny

Journal of Phycology, EarlyView.
Abstract Mallomonas is among the most diverse genera of Chrysophyceae, yet many of its lineages remain taxonomically unresolved due to limited molecular sampling. Mallomonas series Peronoides, historically limited to four species, has posed persistent taxonomic difficulties, most notably the long‐standing and problematic reliance on a rare ...

Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored. Isolated from ancient sugarcane mill ruins within the BAF, the new genus (strain CCAPE130) exhibits a unique ...

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

Journal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

Vicariance and dispersal in the Aegean Archipelago: Molecular phylogeography reveals the origin and divergence times of Hydropsyche (Trichoptera: Hydropsychidae) species

Journal of Systematics and Evolution, EarlyView.
Divergence times of Greek Hydropsyche lineages fall mostly within the Pliocene‐Pleistocene, rejecting ancient vicariance. Widespread species show shallow divergences consistent with dispersal, while island endemics exhibit deeper isolation patterns supporting a mixed vicariance‐dispersal model.
