AI Insight
Researchers from Lingnan University and international collaborators studied tropical intertidal snails living in high-temperature environments to determine whether animals can increase their thermal tolerance in response to climate change. The study found that tropical species are already living near their maximum thermal limits, leaving them with little capacity to adapt to further warming. This suggests that organisms in tropical regions have compressed safety margins and may be particularly vulnerable to ongoing climate change.
Why it matters
This research indicates that tropical species may lack the physiological flexibility to adapt to continued global warming, potentially leading to population declines or local extinctions in these biodiversity-rich regions. The findings highlight the urgent need for climate mitigation strategies to protect tropical ecosystems that are already operating at their thermal thresholds.
Understand the Science
With global warming and extreme weather intensifying, can animals raise their thermal tolerance to cope with a continuously warming environment? A joint research project by the Division of Science at Lingnan University and an international research team conducted experiments on tropical intertidal snails that live under the scorching sun.
