Harold Suárez-Baron, a PhD candidate at the University of Antioquia in Colombia, received a Deland Award at the Arnold Arboretum to study Dutchman's pipevines (Aristolochia), particularly their unusual mechanism for attracting and retaining flies for pollination.
While floral diversity has been studied extensively in animal-pollinated plants, much less is understood about why wind-pollinated plants also exhibit diversity in reproductive structures. Published in Annals of Botany, Juan Losada, Fellow of the Arnold Arboretum, and Andrew Leslie, Assistant Professor at Brown University examined this diversity in conifers. Abstract »
Dr. Marjorie Lundgren, a postdoctoral research associate at MIT and visiting fellow of the Arnold Arboretum, won a British Ecological Society Small Research Grant for a project exploring perenniality in Brachypodium grasses, in collaboration with Professors David Des Marais of MIT and Barry Logan of Bowdoin College. Congratulations Marjorie!
Robin Hopkins was awarded the Harvard Fannie Cox Prize for Excellence in Science Teaching. This awards recognizes Robin's dedication to teaching complex concepts in life sciences while inspiring her students to pursue science careers. Congratulations Robin!
Published in Gene, Austin Garner with colleagues Ben Goulet, Matt Farnitano, Francesco Molina, and Robin Hopkins, review the process of reinforcement, the evolution of traits that prevent costly hybridization. The review article focuses on how genomics can be leveraged to understand reinforcement. Abstract »
Arboretum scientists have pinpointed how mother plants of a water lily species take control of rearing offspring, part of a 25-year quest to understand how mothers and fathers interact in the creation of a flowering plant seed.
Supported by a Sinnott Award, Callin Switzer with colleagues Robin Hopkins and Stacy Combes examined the unique method of pollination in mountain laurel. With the anther filaments acting as catapults, the pollen reaches speeds of 8 miles per hour, making it one of the fastest moving plants in the world! Abstract » Harvard Gazette »
Scientists estimate that food supplies will need to double by 2050 to meet demand. In greenhouse experiments conducted at the Arnold Arboretum, Harvard researchers discovered a way to more than double crop size by introducing a soil bacterium that converts nitrogen from the atmosphere into robust and sustainable fertilizer.
