Environmental Ecology

Swamp microbe has pollution-munching superpower

Publish Date: 
Thursday, April 12, 2018 - 11:45am

Researchers in the lab of PEI associated faculty Peter Jaffe, professor of civil and environmental engineering, discovered a bacterium in a New Jersey wetland that has the surprising ability to degrade pollutants without using oxygen. This could offer a more efficient method for treating toxins in sewage.

Lessons from lemurs: To make friends, show off your smarts

A study of ring-tailed lemurs (Lemur catta) suggests that a clever individual's social position can improve if others see their problem-solving skills pay off, according to a team of Princeton University researchers, including PEI associated faculty Dan Rubenstein, Class of 1877 Professor of Zoology and professor of ecology and evolutionary biology and director of the Program in Environmental Studies.

PEI Faculty Seminar: "Environcide: War, Society, and Environment"

Emmanuel Kreike, Professor of History, presented, "Environcide: War, Society, and Environment," at 12:30 p.m. Tuesday, March 6, in Guyot Hall, Room 10. Kreike was the second speaker in the Spring 2018 PEI Faculty Seminar Series.

Theory suggests root efficiency, independence drove global spread of flora

Researchers from Princeton University and the Chinese Academy of Sciences suggest that plants were able to spread worldwide thanks to root adaptations that allowed them to become more efficient and independent. As plant species spread from their nutrient-rich tropical origins, roots became thinner so they could more efficiently explore poor soils for nutrients, and they shed their reliance on symbiotic fungi. The researchers report that root diameter and reliance on fungi most consistently characterize the plant communities across entire biomes such as deserts, savannas and temperate forests.

Peter and Rosemary Grant to receive BBVA Foundation Frontiers of Knowledge Award

Publish Date: 
Tuesday, February 6, 2018 - 10:30am

Princeton ecologists Peter and Rosemary Grant will receive the BBVA Foundation Frontiers of Knowledge Award in the category of ecology and conservation biology. The Grants were cited for "their profound contributions to our understanding of the mechanisms and processes by which evolution occurs in the wild."

Community-run seafood program, Fishadelphia, links city and Shore

Publish Date: 
Wednesday, February 7, 2018 - 12:00pm

Fishadelphia, a new community-based fishery program in Philadelphia, will launch its pilot program Friday, Feb. 9, to help provide city residents with access to fresh seafood from Jersey Shore fisheries. Talia Young, a Princeton postdoctoral research associate in ecology and evolutionary biology, created the program to promote affordable access to high-quality food in urban communities, while also supporting local fisheries. She created Fishadelphia with assistance from Atarah McCoy '20 (WWS), who worked on the initiative through PEI's Summer Internship Program.

The ecological costs of war in Africa

Publish Date: 
Wednesday, January 10, 2018 - 1:00pm

After years of examining conflict in Africa's protected areas, Princeton researchers Joshua Daskin and Robert Pringle report in the journal Nature that war has been a consistent factor in the decades-long decline of Africa's large mammals. But they also found that wildlife populations rarely collapsed to the point where recovery was impossible, meaning that even protected areas severely affected by conflict are promising candidates for conservation and rehabilitation.

Farms, petroculture and the Environmental Nexus: Four new environmental studies courses and ENV 200 for Spring 2018

Publish Date: 
Monday, December 4, 2017 - 12:00pm

Four new environmental studies courses and the popular "Environmental Nexus" class are among the many Spring 2018 classes from PEI's Certificate Program in Environmental Studies. Registration begins Dec. 6.

Study of Darwin’s finches reveals that new species can develop in as little as two generations

Publish Date: 
Tuesday, November 28, 2017 - 1:45pm

Princeton University researchers B. Rosemary Grant and Peter Grant, along with researchers from Uppsala University in Sweden, have found that a new species of Darwin’s finches developed in as little as two generations, which provides direct genetic evidence of a novel way in which new species arise. The Grants have been studying the evolution of Darwin’s finches on the small island of Daphne Major in the Galápagos Islands for the last four decades.
