DNA from kelp records major earthquake that hit Otago about 1000 years ago
Kelp clinging to the rocky South Otago coast has shown scientists the destructive power of a magnitude 7-plus earthquake that hit the region about 1000 years ago.
DNA testing of kelp at Taieri Beach, at the northern end of an uplifted zone where the Akatore Fault reaches the coast, reveals a "clear genetic difference" from kelp on adjacent shoreline that was not raised by the quake.
University of Otago biologist Professor Jon Waters said the research showed major historic quakes could "leave a lasting DNA signature" in terms of coastal recolonisation, just as the November 2016, magnitude 7.8, Kaikōura quake had.

Many New Zealand gardens aren’t seeing as many monarch butterflies fluttering around their swan plants and flower beds these days — the hungry Asian paper wasp has been taking its toll.
Thanks to people like Alan Baldick, who’s made it his mission to protect the monarch, his neighbours still get to enjoy these beautiful butterflies in their own backyards.
Thinking about planting something to invite more butterflies, bees, and birds into your garden?
Thanks for your mahi, Alan! We hope this brings a smile!
