Repeated coral bleaching events have eroded reef accretion potential in the Florida Keys
Recent research confirms a concerning trend: repeated coral bleaching events have critically eroded reef accretion potential within the Florida Keys. Four severe events—1997–1998, 2005, 2014–2015, and 2023—have demonstrably shifted the region from net reef growth to net erosion, with coral bleaching now recognized as the primary driver of global coral-reef degradation. Longitudinal data analysis reveals that these events, particularly the 1997–1998 episode, account for over 75% of the decline in reef-building capacity since 1996. For deeper
Extreme warming increases metabolic demand and diminishes acidification effects on larval survival in the dog conch Strombus canarium
Rising ocean temperatures and acidification pose escalating threats to marine ecosystems. A recent study investigated the combined impact on *Strombus canarium* larvae, revealing that extreme warming significantly diminishes the effects of acidification on survival. While growth performance responded positively to moderately reduced pH, oxygen consumption increased with temperature. These contrasting responses highlight the potential for altered metabolic demands to constrain larval performance, suggesting thermal stress may become a dominant factor under future warming scenarios.
