Surveying Biodiverse Coral Reef Ecosystems Across the Tree of Life With Environmental DNA

Molecular Ecology Resources, Volume 26, Issue 7, October 2026.
ABSTRACT A central challenge in evaluating biodiversity using environmental DNA (eDNA) metabarcoding is that each primer set has biases resulting in selective amplification of taxonomic diversity. Here we test 11 primer pairs to assess Central Pacific coral reef diversity in the five kingdoms of marine eukaryotes: Chromista, Fungi, Metazoa, Plantae and

Osmomixotrophy in Phytoplankton: Analysis of 46 Strains From Marine and Freshwater Habitats Indicates Prevalent Use of Organic Compounds

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
Analysing thousands of data points across 46 marine and freshwater strains, this study underscores that osmomixotrophy is a common, rather than exceptional, metabolic strategy in phytoplankton. These findings challenge the autotrophic paradigm, demonstrating that organic matter acquisition is a default state with significant implications for our ...

The reportedly low standard quality of heparin (HEP) for use in cardiac surgeries has led to concern in the Brazilian and international markets. Sulfated polysaccharides (SPs) from seaweeds have been regarded as promising substitutes for HEP.

Shift Towards Syndiniales Prevalence in Protist Communities During a Marine Heatwave

Environmental Microbiology Reports, Volume 18, Issue 5, October 2026.
During a marine heatwave, protist diversity decreased and communities became more homogeneous. The parasitic dinoflagellate Syndiniales became the most dominant group in Subtropical Waters and the Southland Front. Since host‐parasitoid interactions are important in carbon and nutrient cycling, they should be considered when studying heatwave impacts on

Giant kelp (Macrocystis pyrifera) gametophytes grow endophytically in red macroalgae: Implications for kelp restoration

Journal of Phycology, Volume 62, Issue 5, Page 1633-1644, October 2026.
Abstract Giant kelp (Macrocystis pyrifera) forests have declined by 95% in Australia since the 1970s due to climate change. Despite expanding restoration efforts, long‐term recovery is still lacking. Factors influencing recruitment by the microscopic gametophyte phase may represent a key mechanism underpinning the successful recovery and restoration of

Synthesis of Green Algal-Based Biochar for Remediation of Arsenic from Contaminated Waters

BioResources
Arsenic (As) contamination of freshwater poses a major global public-health challenge. This study evaluated locally isolated freshwater green macroalgae as a feedstock for producing low-cost biochar for As(III) removal from aqueous solutions.
