Swedish pool frogs grows more rapidly

German Orizaola and Anssi Laurila (Animal Ecology, Department of Ecology and Genetics) have compared how fast pool frog tadpoles grow compared to those from Poland and Latvia. They found that the Swedish frogs have adapted to the cooler climate in Sweden by growing faster than tadpoles from the other two countries when the temperature is warm. When it is colder they all grow at the same rate.
