Scientists have unlocked the koala's behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming of staying cool and avoiding behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming in intense heat. They hug trees. For behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming people thought the cuddly animals clung to behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming to sleep. Researchers from Melbourne University have now cast new behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming on why they hug trees. Lead behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming Natalie Briscoe said a tree trunk is 5 degrees behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming than the air around it. Koalas use the cooler behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming by spreading themselves out on large branches or by hugging the behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming. Ms Briscoe said: "Trees can save about behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming the water a koala would need to keep cool on a hot day."

Briscoe studied the behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming of 37 koalas off the Melbourne behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming. She wanted to find out how koalas might survive global behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming. Her conclusions regarding the behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming effects of the trees surprised her. Koalas sat upright in behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming weather, hugged branches when it became warmer, and wrapped themselves around tree trunks when it got behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming. They even moved to behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming trees that had cooler trunks. She said trees are cooler because of the water they suck up from the behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming. The koala's cooling behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming could help us survive behaviourcoastcoolercoolingdecadesdehydrationdifferentgroundhalfhotincreasinglylightresearchersecretsurfacetechniquetreestrunkwarming hot summers.
