Pleistocene arctic megafaunal ecological engineering as a natural climate solution? by Macias Fauria, M, Jepson, P, Zimov, N, Malhi, Y

“…Here we review the environmental context of megafaunal ecological engineering in the Arctic; explore the mechanisms through which it can help mitigate climate change; and estimate its potential—based on bison and horse, with the aim of evaluating the feasibility of generating an ecosystem shift that is economically viable in terms of carbon benefits and of sufficient scale to play a significant role in global climate change mitigation. …”
