Ecosystem changes in tropics linked to declining upwelling of nutrient-rich waters, long-term study finds

(Phys.org)—Reports of declining ice coverage and drowning polar bears in the Arctic illustrate dramatic ecosystem responses to global climate change in Earth's polar regions. But in this first-ever account of a long-term project in the southern Caribbean, a Stony Brook professor and his colleagues report in this week's Proceedings of the National Academy of Sciences. that tropical ecosystems are also affected by global climatic trends - and with accompanying economic impacts.
