Greater temperature sensitivity of plant phenology at colder sites : implications for convergence across northern latitudes [Global Change Biology]

par Frédéric Magné - publié le

Warmer temperatures are accelerating the phenology of organisms around the world. Temperature sensitivity of phenology might be greater in colder, higher latitude sites than in warmer regions, in part because small changes in temperature constitute greater relative changes in thermal balance at colder sites. To test this hypothesis, we examined up to 20 years of phenology data for 47 tundra plant species at 18 high-latitude sites along a climatic gradient. (...)
