Scientists have unlocked one of the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk as to how koalas stay behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk and avoid dehydration in the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk heat of Australian summers. They hug trees. For behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk people thought the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk marsupials clung to trees simply because they were tired and wanted somewhere to nap. Researchers from Melbourne University have now cast new behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk on the tree-hugging habits of the koala. Lead researcher Natalie Briscoe said there is a five-degree behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk in behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk between a tree trunk and the air. Koalas utilize the cooler surface by spreading themselves out on large branches or by hugging the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk. Ms Briscoe said: "Access to these trees can save about behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk the water a koala would need to keep cool on a hot day."

Briscoe studied the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk of 37 koalas on an island off the Melbourne coast. She is part of a team trying to identify how koalas might survive behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk temperatures brought by global warming. Her behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk and conclusions regarding the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk effects of the trees came as a surprise to her. She noted that the koalas sat upright in cooler weather, hugged behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk when it became warmer, and then wrapped behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk around the tree trunk when it got hot. The animals even moved to behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk trees that had cooler trunks. She said the trees are behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk cooler because of the water they suck up from the behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk. The koala's cooling technique could be one way for humans to survive behaviourbranchescoolcoolingcuddlydecadesdifferencedifferentgroundhalfhigherincreasinglyintenselightobservationsprobablysecretstemperaturethemselvestrunk hot summers.
