Sedimentary records of palaeohydrological variability during the Late Holocene in the Lower Narmada Basin, western India

open access: yesThe Depositional Record, Volume 12, Issue 1, February 2026.
Late Holocene palaeohydrological changes in the lower Narmada Basin, India, revealed using multiproxy analyses of the Orsang River terrace sediments. Distinct depositional phases corresponding to global climatic events were recorded. High‐magnitude floods in the Narmada River during the MWP, and within the tributary Orsang River during DACP and LIA ...

Colonization of a Neotropical Reservoir (Córdoba, Argentina) by Ceratium hirundinella (O. F. Müller) Bergh [PDF]

open access: yes, 2005
Blooms of Ceratium hirundinella (O. F. Müller) Bergh. have been detected in different water bodies in the Neotropical Region since 1990. The colonization began in southern lakes, and during the last decade the dinoflagellate arrived and bloomed in ...

Revealing Seasonal Patterns and Metabolism of Microbial Plankton in a Productive Coastal Upwelling System

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 2, February 2026.
Abstract Increasing our knowledge about the structure and metabolism of the microbial plankton community in coastal upwelling systems is essential for efficiently managing the resources of these highly productive ecosystems. Here we explore seasonal variations of this community in the NW Iberian coastal upwelling system by measuring variables informing

Network Component Analysis Can Identify Potential Axenisation Strategies Circumventing Antibiotic‐Use for Phototrophic Eukaryotic Microalgae

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 1, February 2026.
Network component analysis of published axenisation methods reveals optimal, antibiotic‐free workflows for phototrophic eukaryotic microalgae. Distinct strategies are identified for diatoms, dinoflagellates, and green algae. Verification using microscopy, sequencing, and cell counting enhances reproducibility.
