Bison body size and climate change
The relationship between body size and temperature of mammals is poorly resolved, especially for large keystone species such as bison ( Bison bison ). Bison are well represented in the fossil record across North America, which provides an opportunity to relate body size to climate within a species....

The relationship between body size and temperature of mammals is poorly resolved, especially for large keystone species such as bison ( Bison bison ). Bison are well represented in the fossil record across North America, which provides an opportunity to relate body size to climate within a species. We measured the length of a leg bone (calcaneal tuber, DstL) in 849 specimens from 60 localities that were dated by stratigraphy and 14 C decay. We estimated body mass ( M ) as M = (DstL/11.49) 3 . Average annual temperature was estimated from δ 18 O values in the ice cores from Greenland. Calcaneal tuber length of Bison declined over the last 40,000 years, that is, average body mass was 37% larger (910 ± 50 kg) than today (665 ± 21 kg). Average annual temperature has warmed by 6°C since the Last Glacial Maximum (~24–18 kya) and is predicted to further increase by 4°C by the end of the 21st century. If body size continues to linearly respond to global temperature, Bison body mass will likely decline by an additional 46%, to 357 ± 54 kg, with an increase of 4°C globally. The rate of mass loss is 41 ± 10 kg per°C increase in global temperature. Changes in body size of Bison may be a result of migration, disease, or human harvest but those effects are likely to be local and short‐term and not likely to persist over the long time scale of the fossil record.
