Moveable, cloning sponge could jumpstart degraded harbours

Researchers identified the Mediterranean sponge Chondrosia reniformis as the sole species among five tested that survived and thrived after transplantation into a degraded marina, showing movement, biomass stabilization, and natural cloning that increased its numbers from 24 to 40. Using computer vision and Life Boosting Units—plates of recycled ceramic on metal structures with calcium carbonate—the sponge acts as a habitat engineer and could underpin harbour restoration, though it is intended as a foundation alongside broader re-naturalisation strategies. The study, led by Manuel Maldonado and Carlota Escarré of CEAB-CSIC Blanes in collaboration with Ocean Ecostructures, appears in Frontiers in Marine Science.

Diploid Hybrid Drives Fast Spread of Invasive Salvinia Fern

New genome analysis shows Salvinia molesta is a diploid hybrid, not the previously assumed allopentaploid, causing meiotic mispairing and preventing sexual reproduction; instead, the fern spreads clonally by fragments that become genetically identical plants, forming dense mats that disrupt freshwater ecosystems. This clonality could make management more predictable and potentially reduce time and costs to restore affected lakes and ponds.

Utah's Ancient Pando: Earth's Oldest Living Organism?

Pando, a massive quaking aspen in Utah, is potentially one of the oldest and largest organisms on Earth, with new research suggesting it could be between 16,000 and 80,000 years old. This clonal organism, consisting of around 47,000 stems connected by a vast root system, has shown remarkable resilience to environmental changes over millennia. The study, which is not yet peer-reviewed, highlights Pando's genetic stability and suggests its age could provide insights into plant resilience and biology. Efforts to protect Pando from grazing have led to signs of its recovery.

Unlocking Ancient Tree Secrets: Clonal Mutation Insights

A team of researchers has sequenced the Pando aspen, one of the world's oldest trees, to study mutations in clonally reproducing organisms. The Pando aspen, a triploid species that reproduces by cloning, occupies 42.6 hectares in Utah's Fishlake National Forest and is estimated to be between 16,000 and 80,000 years old. The study identified approximately 4,000 genetic variants in the tree, highlighting its unique evolutionary traits, such as larger cells and enhanced fitness, which contribute to its longevity.
