How will migrating birds, like the golden plover that overwinters in Africa, know when the right time is to come? Will bumblebees be born at the right time of the year, when plants are flowering? If animals and plants are out of sync, we call it a mismatch. Good timing, being at the right time and right place, is important for the plants and animals of Abisko. This likely mismatch means birds might arrive too late to breed and use all the surplus in food or bumblebees might be out at the wrong time to pollinate.
