The last time the world was significantly warmer than today. Unfortunately, the relationship between carbon dioxide and temperatures were out of whack too.

The Future of Fish Feed, or F3, is a collaboration between nongovernmental organizations, scientists and the private sector to uncover new alternative feed ingredients for aquaculture that reduce or eliminate reliance on wild-caught fish. The UA is among the institutions supporting the project.
Swollen shoot is unique to West Africa, where about three-quarters of the world's cocoa is grown. The disease was identified nearly a century ago, yet scientists say a cure is years away and early detection methods are only just being introduced. "I wish more people would understand the sort of magnitude of the lives impacted," said Judith Brown, a virologist studying swollen shoot at the UA.
University of Arizona researchers found a tight link between temperature and plant and microbe communities within forests, which will allow them to predict how ecosystems might respond to climate changes.
An article examines whether the Amazon Rainforest truly produce 20% of the Earth’s oxygen. Some scientists estimate the percentage is closer to 6-9%, and the Amazon ultimately consumes nearly all of that oxygen itself. "With a little more analysis and a more thorough review of the literature, we could probably derive a slightly better estimate with more specific uncertainties," said Scott Saleska, a UA ecosystem ecologist who agreed with the 6-9% approximation.

Anthropologist María Nieves Zedeño combines traditional knowledge and scientific archaeology to explore how, for millennia, indigenous hunters in North America treated bison as powerful persons and partners who shaped every aspect of human life.
