City mouse-country mouse study shows how environment affects susceptibility to worm infections
March 14, 2018

A study by Jacqueline Leung, Andrea Graham and colleagues shows that movement of laboratory mice to a natural, farm-like environment rapidly alters their gut microbiome and immune responses, and increases their susceptibility to intestinal worm infections. 

Q&A with professor Corina Tarnita
March 13, 2018

Dr. Corina Tarnita is a professor and mathematical biologist in EEB. She teaches a freshman seminar FRS 191: The Equations of Life and undergraduate Carolyne Davidson recently met with her to ask some questions about her background and career. 

Theory suggests root efficiency and independence drove global spread of flora
Feb. 26, 2018

EEB professor Lars Hedin, EEB graduate student Mingzhen Lu and scientists from the Chinese Academy of Sciences led the proposal of a new theory of plant evolution. It suggests that the 400 million-year drive of flora across the globe may not have been propelled by the above-ground traits we can see easily, but by underground adaptations that…

Competing for blood: How ecologists are solving infectious disease mysteries
Feb. 21, 2018

Princeton ecologists professor Andrea Graham and postdoc Sarah Budischak were able to explain why co-infected patients got sicker after being dewormed: without the hookworms to keep them in check, the malaria infection ran rampant.

Peter and Rosemary Grant to be awarded the BBVA Foundation Frontiers of Knowledge Award
Feb. 7, 2018

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 acknowledged for "their profound contributions to our understanding of the mechanisms and processes by which evolution occurs in the wild."  The foundation noted that…

Chris Tokita is a force for science with the American Association for the Advancement of Science (AAAS). Tokita took a two-year gap before graduate school to work as a Science Policy Fellow at the IDA Science and Technology Policy Institute in Washington DC, a center tasked with supporting the White House Office of Science and…

Warfare and wildlife declines in Africa’s protected areas
Jan. 22, 2018

Frequent armed warfare in many of Africa’s nature reserves has contributed to the decline of some of the continent’s iconic beasts. To understand the overall effect of warfare on wildlife, Joshua Daskin and Robert Pringle at Princeton University analysed data collected between 1946 and 2010 on more than 250 populations of large herbivorous…

A mathematician who decodes the patterns stamped out by life
Jan. 22, 2018

Corina Tarnita deciphers bizarre patterns in the soil created by competing life-forms. She’s found that they can reveal whether an ecosystem is thriving or on the verge of collapse. Of all the patterns Tarnita explores, one of the most enchantingly enigmatic are fairy circles: barren round patches that dot the grasslands of Namibia like…

Corina Tarnita's journey to discovering biology all over again, through the lens of mathematics
Jan. 17, 2018

Assistant professor Corina Tarnita conducts fascinating research on the causes and consequences of emergent patterns in complex systems, such as the regular vegetation patterns found in arid ecosystems worldwide. Her journey to get to this place in her career is not a conventional one. It started back in her home country of Romania where she…

Study of Darwin’s finches reveals that new species can develop in as little as two generations
Nov. 28, 2017

The arrival 36 years ago of a strange bird to a remote island in the Galápagos archipelago has provided direct genetic evidence of a novel way in which new species arise. On Nov. 23 in the journal Science, researchers from Princeton University and Uppsala University in Sweden report that the newcomer belonging to one species mated with a member…
