Groundwater Microbial Diversity Associated With Icelandic Basaltic Subsurface Environments

Environmental Microbiology Reports, Volume 17, Issue 6, December 2025.
Overview of microbial diversity and environmental drivers in Icelandic deep basaltic aquifers. Using 16S rRNA gene metabarcoding across 22 geothermal wells spanning broad temperature, pH, and bedrock‐age gradients, the study reveals distinct bacterial and archaeal community structures shaped by temperature, pH, and host‐rock reactivity.

A hitchhiker's guide to modern, practical cyanobacterial taxonomy

Journal of Phycology, Volume 61, Issue 6, Page 1536-1552, December 2025.
Abstract There has been an explosion of new Cyanobacterial taxa described within the last two decades. Cyanobacteria exhibit incredible ecological versatility and morphological variability, and thousands of species have already been described using “traditional” approaches (e.g., morphological features).

Climate Emergency and Different Ways to Fail? The Fermi Paradox, the Simulation Hypothesis, Agency and Hope

Journal for the Theory of Social Behaviour, Volume 55, Issue 4, December 2025.
ABSTRACT Humanity seems stuck on different ways to fail to meet the challenge posed by a declared climate emergency and manifest the problems of ecological breakdown. Rather than reprise these failures, we use the Fermi Paradox and simulation hypothesis to make a simple point about agency. The argument unfolds in two sections.

Blue Supergiants in the Pinwheel Galaxy M101: Comparison with H II Region Chemical Abundances, Spectroscopic Distance, and an Independent Determination of the Hubble Constant

The Astrophysical Journal
We present a quantitative spectroscopic study of 13 blue supergiant stars in the Pinwheel Galaxy M101, based on data obtained with the Low Resolution Imaging Spectrometer available at the Keck I telescope.

Unravelling Hidden Trophic Interactions Among Sea Urchin Juveniles and Macroinvertebrates by DNA Amplification

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Rocky reefs may shift between two distinct stable states: productive algal forests, characterised by high abundance and biodiversity of macrofauna, and impoverished barrens, dominated by overgrazing sea urchins. Barren states may persist despite the recovery of adult sea urchin predators, suggesting additional stabilising mechanisms.

Large‐Scale Integrative Taxonomy of the Smallest Insects Reveals Astonishing Temperate Diversity (Hymenoptera: Chalcidoidea: Mymaridae)

Molecular Ecology, Volume 34, Issue 24, December 2025.
ABSTRACT Fairyflies (Hymenoptera: Chalcidoidea: Mymaridae) are a diverse but taxonomically understudied group of parasitoid wasps that attack the eggs of other insects. Being among the very smallest of all insects, they are often ignored in biodiversity surveys despite being one of the most abundant microhymenoptera in many habitats.
