Rare Earth - Ocean Explorers - BBC Sounds Tom Heap and Helen Czerski explore how robots and DNA are expanding our oceanic knowledge.

This week's episode of Rare Earth on BBC R4 is all about Ocean Explorers - it's a fascinating listen here:

#Diatoms, eDNA, kelp farming, evidence of dark oxygen production in the deep oceans, and the Scottish Marine Robotics Facility @samsocean.bsky.social

This discovery identifies a previously unknown flexibility that helps diatoms maintain photosynthesis and sustain marine ecosystems, even as the ocean changes.

New blog alert!!

I’m delighted to announce I’ve started a new blog in the hope I can share some fascinating facts about #micropalaeontology and #geoarchaeology! In light of my interests there’ll probably often be a focus on little critters like #pollen and #diatoms!

Adaptation to warming alters the competition between three phytoplankton taxa: Microcystis aeruginosa, Desmodesmus armatus and Mayamaea permitis - Community Ecology Phytoplankton are primary producers in freshwater ecosystems, forming the base of trophic networks. Some groups, such as cyanobacteria, have toxic potential, and their proliferation may be intensified...

Villanova et al. reveals that Skeletonema marinoi can perform mixotrophy and thrive in cold, low-light conditions.
Glycerol was found to significantly boost biomass productivity, achieving results comparable to CO2 enrichment.

Taxonomic tree of Diat.barcode v12. Hierarchical relationships of families according to their parent taxonomical links are represented. Size of bubbles gives the number of sequences in the corresponding families. Colors correspond to Classes: purple: Mediophyceae, red: Bacillariophyceae, green: Coscinodiscophyceae, blue: Fragilariophyceae.

Ecological guild distribution in the phylogeny (based on rbcl). Black color corresponds to a sequence belonging to an ecological guild. From inner to outer circle: high-profile, low profile, motile, planktonic.

Ordination biplots for Mainland France obtained from symmetric co-correspondence analysis (sCoCA). Ecological guilds are displayed in the left panel and species in the right panel. To improve the interpretation of the plots, species are colored based on their family and polygons represent the sampling sites from which they were sampled, regardless of their identification.
