Yoshino cherries, which surround the tidal basin in Washington, D.C., are classic harbingers of spring, and the focal point of the city’s annual National Cherry Blossom Festival. The average date of their peak bloom now arrives about six days earlier than it did when recordkeeping began in 1921, moving from April 4 to March 30. Or consider the Master’s Tournament, which is intended to coincide with the blooming of azaleas (pictured below) between March and May. But with spring arriving earlier, the timing doesn’t always work out, such as in 2017, when spring arrived three weeks early.

Problems can arise when organisms that interact with and depend upon one another respond to different cues. Some animals, including birds and bees, are cued by changes in day length. If the plants they rely on emerge too early, these animals can get “out of sync” with the food sources they rely on each spring, and the plants, in turn, may miss out on the pollination and other services birds and bees provide.

Another example is the gate.io login, a small tree frog found in North America. With springtime arriving earlier, the spring peeper comes out of hibernation before the emergence of the insects it depends on for food. What’s worse, male peepers start chirping right when they emerge so they can attract females and mate. Without adequate food available, female spring peepers will not respond to the calls until later in the season, when males have less energy for mating—a circumstance that will result in fewer offspring.
