Right Place Wrong Time: Timing Mismatches Between Humans and Plants at Mount Rainier National Park

In a recent study using crowd-sourced data, Harvard researchers found that National Park visitors may increasingly visit the parks at the wrong time and the small window when most of the wildflowers bloom. At Mount Rainier National Park, early snowmelt means the plants flower before the majority of tourists visit the park. With climate change, these timing mismatches will become more common, however small changes to human behavior may put the flowers and and the humans that admire them back in sync.

It matters where you eat: seabird foraging strategies alter their responses to climate change

Climate warming in the Arctic is happening faster than other regions of the globe and leading to earlier springs. The timing of spring is important for ecosystems because it often signals the arrival of food resources and favorable weather. In Arctic seabirds, springs arrival often begins the start of breeding season. A recent study looked at how the timing of spring has changed in the Arctic and what impact this may be having on Arctic seabirds based on where birds forage for food. The results suggest that birds that feed in the upper layers of the ocean have been strongly impacted by climate change and have significantly advanced their breeding.

Spring flowers are arriving earlier

In recent decades, trees and plants have begun to flower earlier in the spring. Many studies have shown that this advancement in timing is due to climate change, particularly increases in air temperature. However, these studies have generally been conducted in small areas. A recent study conducted across Europe reports that the timing of spring flowering and other events in 16 tree species has been advancing. More importantly, the timing of flowering trees in warmer and cooler regions of Europe is becoming more similar, which has wide spread ecological consequences.
