Presenters describe spawning lab to increase coral genetic diversity and resilience
Summary
Speakers at a meeting discussed coral restoration approaches, saying current cloning methods produce low genetic diversity and describing a planned coral spawning lab aimed at producing greater natural genetic variation to select for thermal tolerance and disease resistance.
Presenters at a meeting described plans for a coral spawning lab they said could increase genetic diversity in reef restoration and help identify corals more tolerant of warming and disease.
"Do you think a coral is an animal, a plant, a mineral, or a microbe? And the actual answer is it's all 4," said Speaker 1, a presenter, opening the discussion on reef ecology and climate impacts. The speaker said many reefs have died and that current restoration has relied on cloning: "we've just been cloning corals. We've been cutting little pieces, growing them in underwater…
