Biodiversity ranks with climate change, pollution in affecting planet's health, team says

J. Emmett Duffy, David Hooper, Bruce Hungate

A research team including David Hooper (2006), Emmett Duffy (2006), and Bruce Hungate (2004) has found that future loss of species could impact ecosystem health and productivity as much as global warming and pollution. They are the first group to make a comprehensive comparison of the impacts of biodiversity loss with the effects of other environmental changes. The team emphasizes the need for stronger efforts to protect biodiversity, which supports nature’s ability to provide services such as food, clean water, and a stable climate.

Commercializing genes to preserve Mexican oasis

Valeria Souza

In an effort to save the Cuatro Ciénegas basin in Mexico, Valeria Souza (2011) has taken an unusual approach: working with local communities and the federal government to commercialize genes that may have useful applications. She recently won a permit from the federal government to proceed. The 40-kilometer-long basin hosts more than 70 native aquatic species and a number of unique organisms similar to some of the earliest life on Earth. However, many ponds have dried out due to groundwater extraction for ranching and farming. Souza hopes that sharing patent profits from the commercialized genes will encourage the local communities to stop the extraction.

Presidential leadership sought on protecting biodiversity

Gretchen Daily, Jonathan Patz, Diana Wall

Gretchen Daily (1999), Jonathan Patz (2005), Diana Wall (1999), and colleagues from academe, corporations, philanthropies, and NGOs submitted a special report to President Obama urging government intervention on threats to the nation’s biodiversity and ecosystems. The report explains why government has an essential role in the stewardship of environmental capital to protect society and the economy. It also suggests specific measures to improve both the government’s and the private sector’s performance in preserving these crucial assets most cost-effectively.

Study details essential role of biodiversity

Loss of biodiversity reduces ecosystem productivity, efficient nutrient use, and decomposition rates, according to a study by an international team of scientists including Patricia Balvanera (2008), Emmett Duffy (2006), and David Hooper (2006). Duffy calls the study "the most rigorous and comprehensive analysis yet" that details the once-controversial idea that diversity is essential to a healthy ecosystem.
