Five PhD students/candidates pursuing research at the Harvard Forest have recently received competitive awards and fellowships to support their work.
Ahmed Hassabelkreem Siddig (pictured at left) has earned a Student Dissertation Research Grant from the University of Massachusetts, to support his efforts to create a more informative measure of indicator species "effectiveness" for ecological monitoring and conservation in declining ecosystems.
An innovative new study led by HF senior ecologist Aaron Ellison and Summer Research Program student Jennie Sirota was published today in the Proceedings of the National Academy of Sciences. The NSF-funded study investigated the factors that cause some lakes and ponds to shift from a clear, oxygen-rich state to an irreversible green sludge.
The complex system of aquatic life that resides inside a carnivorous northern pitcher plant is the subject of a new study by post-doctoral fellow Ben Baiser and senior ecologist Aaron Ellison. These tiny, wriggling organisms--mosquito larvae, mites, rotifers, and copepods--are crucial to the pitcher plant’s ability to process food.
On the blog for the HF Summer Research Program in Ecology, our students describe their 11-week summer experience in their own words. Blog features include research project profiles, weekend excursion reports, and updates from program alumni.
2012 features so far: state changes in carnivorous plants, underground photography of root growth, native bumblebee and butterfly diets, and building a low-cost water filtration system.
On May 21st, 29 students arrived at the Harvard Forest from around the country and the world, to take part in our 2012 Summer Research Program in Ecology. For 11 weeks, these students will live on-site and be mentored on a full-time, independent research project.
Scientists at the Harvard Forest are trying to answer a question that is now more than 100 years old: how did the 11 different species of North American pitcher plant evolve? A new paper by Research Fellow Wyatt Oswald, Research Assistant Elaine Doughty, former Bullard Fellows Gidi and Rina Ne'eman, and Senior Ecologist Aaron Ellison, adds new insight to the relationships between these 11 species by showing differences in the shape and size of the plants' pollen.
On Monday, October 3 at 7:00pm, senior ecologist Aaron Ellison will present a special lecture at Coolidge Corner Theatre in Brookline. The event is the season opener of the theatre's popular "Science On Screen" series, which pairs film screenings with creative introductions by notable science figures.
The research by Harvard Forest senior ecologist Aaron Ellison and University of Vermont professor Nicholas Gotelli on the evolutionary ecology of carnivorous plants is highlighted in the March 2010 issue of National Geographic magazine, click here to read the article.
Recent Harvard Forest post-doc Jim Karagatzides has published two papers based on his research with Harvard Forest Senior Ecologist Aaron Ellison. In the first, using stable isotope tracers in the field, Jim showed that Sarracenia purpurea can acquire nitrogen directly from amino acids, bypassing the inorganic nitrogen cycle on which most plants depend for their primary nutrient.
