Ant biodiversity and ecosystem services in bioenergy landscapes

Most strategies for limiting global climate change invoke the use of bioenergy, but biofuel crops vary in climate mitigation potential and in the provision of other ecosystem services. The predominant biofuel in North America is ethanol produced from corn Zea mays. Corn is grown on ∼360,000 km2 of land in the U.S. and ∼40 % of the yield is used for ethanol production. Despite its prevalence, corn ethanol is a poor climate change mitigator and...
