Synopsis

  • This video provides evidence to show that animals are shrinking in a warmer climate. Evidence includes graphs and pictures with changes in bird size over the past 40 years and references to articles that discuss shrinking amphibians and mammals.
  • The video also describes the consequences of changing animal sizes. Animals may not be able to migrate as far, they may have fewer offspring, and there can be major ecological consequences as interspecific relationships change.
  • While not all animals may shrink, and some may even grow large, the physiology, ecology, and consequences of these changes is examined and explained. The mechanisms of selection pressure and developmental plasticity are explained.
