Genomic insights into the origin of ecotypes
A century after Turesson introduced ecotypes as locally adapted subunits of species,
their origins and nature remain debated. Recent advances in molecular ecology have
breathed new life into the ecoty...

Since Christmas is soon here with all its strange traditions:
The christmas chocolate tennis racket from Bergen (Norway)! Since the 70s a "must-have" for people in Bergen, nobody knows why. Since I live in Bergen I have to have some, of course😊

Plasmid streamlining drives the extinction of antibiotic resistance plasmids under selection for horizontal transmission
Conjugative plasmids play an important role in the spread of antimicrobial resistance (AMR) genes among pathogenic bacteria. This study shows that AMR loss in evolving populations is associated with the evolution of streamlined plasmids that gain a transmission advantage by deleting all of their AMR genes.

Decadal scale phytoplankton species miniaturization in subtropical coastal waters
Abstract. Miniaturization, i.e. reduction in body size, happens in different organisms as an adaptation strategy under environmental stress such as warming

The shift that sparks nitrification: PML research resolves long-standing mystery within the nitrogen cycle
New PML research has shed light on a long-standing puzzle in marine science: why does nitrification – a key process in the ocean’s nitrogen cycle – only ‘switch on’ under certain conditi

A re-examination of Laminaria gunneri reveals it to be synonymous with Hedophyllum nigripes (Laminariales, Phaeophyceae) www.tandfonline.com/doi/full/10....
Analyzing kelps from Berlevåg fitting Foslie's description of Laminaria gunneri (from 1885) showed that it was Hedophyllum nigripes 😊
