COVER A blue-throated barbet (Psilopogon asiaticus) eats a fig in southern Bhutan, dispersing the seeds within. Seed-dispersing animals help fleshy-fruited plants adapt to climate change by moving seeds to suitable habitats. However, many seed dispersers are in decline, endangered, or extinct. Bird and mammal population losses have caused an estimated 60% decline in seed dispersal, limiting plants’ ability to track climate change. See page 210.
