Slight rises in temperatures are triggering rainforest trees to produce more flowers, reports a new study published in the journal Nature Climate Change. The research is based on observations collected in two tropical forests: a seasonally dry forest on Panama’s Barro Colorado Island and a “rainforest” with year-around precipitation in Luquillo, Puerto Rico. The authors, led by Stephanie Pau, currently at Florida State University but formerly from UC Santa Barbara, analyzed the impact of changes in temperature, clouds and rainfall on flower production. They found an annual 3 percent increase in flower production at the seasonally dry site, which they attributed to warmer temperatures.
