Drivers and Consequences of Size Declines in Unicells

Ecology Letters, Volume 29, Issue 5, May 2026.
Previous syntheses concluded that metabolic allometric scaling is unusually steep (> 1) in unicells but here we show that this steepness is an artefact of laboratory studies that confound cell size with cell population density. Once this density effect is accounted for, metabolic scaling is ~0.86 in unicells.

A Hanks‐type bacterial kinase, PknS, directly phosphorylates the alternative sigma factor EcfK to promote resistance to protist predation

The FEBS Journal, Volume 293, Issue 9, Page 2772-2793, May 2026.
The Xanthomonas citri Hanks‐type kinase PknS autophosphorylates and directly phosphorylates the alternative sigma factor EcfK at five residues. Besides the conserved residue T51 in the σ2 domain, phosphorylation of a residue in the linker between σ2 and σ4 is critical for EcfK activation by promoting its interaction with a positively charged pocket in ...

Compound‐Specific Stable Isotope Analysis Reveals Population‐Specific Differences in Chinook Salmon Trophic Level and Basal Resource Use in the Northeast Pacific

Fisheries Oceanography, Volume 35, Issue 3, Page 397-412, May 2026.
ABSTRACT Chinook salmon exhibit far‐flung and disparate population‐specific marine migrations that have made it difficult to assess their trophic ecology. In this study, we collected returning and resident subadult Fraser River Chinook salmon in 2018 and 2019 from population groups with different known run‐timings (spring, summer, and fall) and marine ...

Fungal Diversity in a Mountain Lake Is Explained by Weather Patterns

Freshwater Biology, Volume 71, Issue 5, May 2026.
ABSTRACT Fungi are an important component of aquatic ecosystems because of their multifaceted roles such as organic matter decomposition, nutrient cycling and energy transfer to higher trophic levels. Despite their importance, little is known about the diversity and ecological functions of fungi in mountain lakes in general and specifically for ...

Protistan Predators Outshine Fungi in Forest Soil Activity

Journal of Eukaryotic Microbiology, Volume 73, Issue 3, May/June 2026.
ABSTRACT Despite extensive research on fungal communities in forest soils, our understanding of the whole eukaryotic diversity and distribution remains limited. Moreover, traditional amplicon sequencing methods often introduce severe PCR and primer biases, further hindering accurate assessment of the microbial community composition in forest soils.
