The timing of the first leaves on trees and plants can make or break an agricultural season. Too early, and the leaves might be blasted by the last frost. Too late and they miss out on maximizing the growing season.
But as climate change brings warmer-than-usual winters to the U.S., the plants may be more vulnerable to imprecise timing, and the tools traditionally used by farmers and horticulturists to predict the season may be inadequate. [more]

Many climate studies have predicted that tree species will respond to global warming by migrating via seed dispersal to cooler climates. But a new study of 65 different species in 31 eastern states finds evidence of a different, unexpected response… [more]
When stomata are open, the trade-off between water loss through transpiration and CO2 uptake via photosynthesis is a result of the evolutionary history of land plants from green algae… [more]
From the announcement: I am pleased to announce this year’s winner of the Dean’s Award for best PhD student manuscript:
Denis Valle for his paper: Conservation Efforts May Increase Malaria Burden in the Brazilian Amazon, in PLOS ONE Volume 8, issue 3. Denis will receive an award of $3,000 for his paper.
The National Science Foundation (NSF) awards a Doctoral Dissertation Improvement Grant (DDIG) to Kai Zhu for support of the project entitled “DISSERTATION RESEARCH: Forest climate requirements change through species life history.” This award is effective May 1 , 2013 and expires April 30, 2014. [more]
Rapp et al. paper in Ecology: “Populations within species are generally assumed to be less productive at colder temperatures, but this study demonstrates that this assumption may not hold in tropical forests.” [more]
Kai Zhu receives the Ecological Society of America (ESA) 2012 Outstanding Research in Ecology by a Graduate Student Award on August 7 at the ESA annual meeting in Portland, OR. [more]
Kai Zhu has been named winner of this year’s Dean’s Award for Outstanding PhD Student Manuscript of Duke University’s Nicholas School of the Environment. He was honored for his entry, “Failure to migrate: lack of tree range expansion in response to climate change,” which was published in Global Change Biology. He will be acknowledged at this year’s graduation ceremony on May 12, and receive a check for $1,500. [more]
“The National Science Foundation has awarded a grant totaling $4,273,484 to fund the study, which aims to provide the first probabilistic forecasts of combined forest biodiversity responses to climate change, including growth, reproduction and mortality risk, directly linked to the process scale…” [more]
“Researchers at Duke developed a novel statistical model that is able to devise new ways of identifying people who are infected with malaria but don’t show symptoms of infection…” [more]
“Zhu, Woodall and Clark use a relatively simple and elegant approach to analyze forest inventory analysis (FIA) data… [T]he work is a valuable contribution and gives sufficient evidence that range responses of trees to climate change will not be as simple as a little bump to the north…” links to F1000 evaluation and GCB article.
Duke’s competitive Katherine Goodman Stern Fellowship has been awarded to Denis Valle for the 2012-13 academic year, selected from nominations university-wide.
