coral bleaching
- High-frequency temperature variability mirrors fixed differences in thermal limits of the massive coral Porites lobata
Summary: Corals native to highly variable habitats demonstrate greater thermal tolerance than corals from less variable habitats after 36 days of acclimation to thermally stable or variable common garden treatments.
- The sphingosine rheostat is involved in the cnidarian heat stress response but not necessarily in bleaching
Summary: Hyperthermal stress of the sea anemone Aiptasia pallida results in rapid symbiont loss that precedes a shift in signaling sphingolipids towards cell death after prolonged exposure.
- Tenacious D: Symbiodinium in clade D remain in reef corals at both high and low temperature extremes despite impairment
Summary: Algal symbionts in Symbiodinium clade D may reduce cnidarian bleaching susceptibility not by resisting temperature stress, but by resisting expulsion.
- Warm preconditioning protects against acute heat-induced respiratory dysfunction and delays bleaching in a symbiotic sea anemone
Summary: Changes in mitochondrial function by thermal preconditioning provide some protection to a symbiotic sea anemone against the effects of stressful heating.
