6. Animals may shrink
Warming climate may favor small species over large ones. The research, based on analysis of body mass of fish, plankton, and bacteria in European ecosystems, comes just weeks after scientists reported that sheep on a Scottish island are shrinking due to warmer conditions.
The new study reveals that individual species lost an average of 50 percent of their body mass over the past 30 years. The reduced body size is the third universal ecological response to global warming. An earlier sheep study suggested that shorter and milder winters mean lambs do not need to put on as much as weight as they once did in order to survive their first year of life, a factor that could also impact fish populations. Nonetheless the researchers say the shift could alter food chains, with apex predators being particularly affected by shrinking prey.
