If the models are successful in correctly showing past climate, there is much greater confidence that they are accurate in showing what future climate is likely to be.
Different grasses, those that grow in warm and cool seasons for example, have different isotope ratios.
The results provided a means to reconstruct temperature patterns for particular locations at particular times, Hoppe said.
They were the most abundant herbivores following the last ice age until Europeans began to settle the continent.
Because there were so many over such a large territory, Hoppe said, bison are an ideal means to study how climate and vegetation fluctuated over thousands of years.
Of course, the venison and bison can be substituted with beef and ground turkey or chicken, if that’s more your style.
