Genetic hotspots for conserving Southern Ocean benthic biodiversity Lau et al. examine multi-species genetic patterns of Southern Ocean benthic biodiversity to identify genetic hotspot areas for priority conservation.

Locating hotspots of high genetic diversity, connectivity and divergence for priority conservation in the Southern Ocean

Millennial-scale societal shifts drive the widespread loss of oyster reefs in East Asia Lau et al. uncover how millennial-scale overexploitation and societal shifts drove the collapse of historically extensive oyster reefs along >750 km of southern China’s coast by the 20th century, high...

Forgotten oyster reefs and lost social history. We dug through historical archives to unearth this ecological-human connection in the world’s largest megalopolis. Leveraging the deep cultural connections to tradition can energise oyster restoration efforts in Asia.

SAEF scientists identify priority Southern Ocean genetic hotspots for conservation | Securing Antarctica's Environment Future New research shows that maintaining and adopting proposed marine protected areas (MPAs) in the Southern Ocean could almost double the protection of genetic hotspots from 28% to ~54%.  For the first ti...

Out now in @currentbiology.bsky.social we used genetic data from a suite of Antarctic marine invertebrates to map locations of genetic diversity hotspots, divergence and connectivity 🐙🦐🪱🧬 @lausally.bsky.social @janstrugnell.bsky.social

What octopus DNA tells us about Antarctic ice sheet collapse Did the enormous West Antarctic Ice Sheet collapse the last time global temperatures were 1.5°C above preindustrial levels? The answer lay in the DNA of an octopus.

Genomic evidence for West Antarctic Ice Sheet collapse during the Last Interglacial Genetic analyses of a type of octopus found around Antarctica show that the West Antarctic Ice Sheet collapsed during the last interglacial period.
