Diversity, Function and Activity of DNA Viruses in the Qiangyong Proglacial Lake Sediment, the Tibetan Plateau

Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.
This study identified DNA viruses from Qiangyong proglacial lake sediments on the Tibetan Plateau, revealing a highly diverse and previously uncharacterized viral community. These viruses influence microbial community structure and function by infecting key nutrient‐transforming taxa and encoding auxiliary metabolic genes that modulate host metabolism.

Modelling N₂ fixation related to Trichodesmium sp.: driving processes and impacts on primary production in the tropical Pacific Ocean [PDF]

Biogeosciences, 2018
Dinitrogen fixation is now recognized as one of the major sources of bio-available nitrogen in the ocean. Thus, N2 fixation sustains a significant part of the global primary production by supplying the most common limiting nutrient for phytoplankton ...

Actualización de la distribución de Boeckella gracilis (Daday, 1902) (Crustacea, Copepoda) en la Región de la Araucanía (38°s), Chile, y un modelo nulo para comprender sus asociaciones específicas en su hábitat [PDF]

, 2012
The crustacean zooplankton of Chilean inland waters are characterized by abundant calanoid copepods, mainly from the genus Boeckella. The present study aims to update the distribution of Boeckella gracilis in the inland waters of the Araucania region (38-

Microbial carbon use efficiency predicted from genome-scale metabolic models [PDF]

, 2019
Respiration by soil bacteria and fungi is one of the largest fluxes of carbon (C) from the land surface. Although this flux is a direct product of microbial metabolism, controls over metabolism and their responses to global change are a major uncertainty

Experimental evidence for the “greening” of proglacial streams: Biofilm responses to a transition from glacial to groundwater sources

Limnology and Oceanography, Volume 71, Issue 1, January 2026.
Abstract Climate change‐induced glacier retreat leads to the reorganization of fluvial landscapes in proglacial terrains and transitions between streams fed predominantly by glacial meltwater and groundwater. To explore the effects of such ecosystem transitions on benthic biofilm communities, we gradually mixed water from a glacier‐fed stream (GFS) and

Gems From the Caves: Genomic Insights Into the Biosynthetic Potential of Antimicrobial‐Producing Bacteria Associated With Tropical Cave‐Dwelling Sponges

Environmental Microbiology, Volume 28, Issue 1, January 2026.
Our study reveals that cave‐dwelling marine sponges host bacteria with antimicrobial activity against multidrug‐resistant strains. The bioactive Pseudomonadaceae strains exhibited biosynthetic clusters encoding both characterized and putative antimicrobial compounds and peptides. The findings highlight their potential for discovering novel biomolecules

Simulating the ocean’s chlorophyll dynamic range from coastal upwelling to oligotrophy

Progress in Oceanography, 2018
Abstract The measured concentration of chlorophyll a in the surface ocean spans four orders of magnitude, from ∼0.01 mg m−3 in the oligotrophic gyres to >10 mg m−3 in coastal zones. Productive regions encompass only a small fraction of the global ocean area yet they contribute disproportionately to marine resources and biogeochemical processes, such ...

New determination of Pediastrum orientale in polar lake sediments and its palaeoecological implications – Reindeer Lake, Bellsund, Spitsbergen

Acta Palaeobotanica
The main component of microfossils in the bottom sediments of Reindeer Lake from Spitsbergen, documenting the almost 8,000-year history of this water body, are algae representing colonies of a very rare species Pediastrum orientale (Skuja) Jankovská et

Eutrophication and endangered aquatic plants: an experimental study on Baldellia ranunculoides (L.) Parl. (Alismataceae) [PDF]

, 2018
Anthropogenic enrichment of aquatic ecosystems is an increasingly common phenomenon, resulting from human population growth and the intensification of industrial and agricultural developments.
