Trees typically experience mid-day water depressions due to water evaporating out of the plant's stomata (a tiny opening or pore in plant leaves that intakes carbon dioxide, which is needed for photosynthesis). To understand how the water stress influences carbon's movement from the leaves (where production begins) to the roots, trunk and shoots (where the water is needed), PhD candidate Jessica Gersony (Holbrook Lab) measured carbon and water traits of five mature red oak trees over the course of 24 hours at Harvard Forest.
Congratulations to PhD candidate Austin Garner (Hopkins Lab) recipient of the Graduate School of Arts and Sciences Graduate Student Council Summer Research Award for his project, "Revealing the evolutionary history of speciation by reinforcement through genetic variation in Phlox flower color."
When Harvard classes moved online, PhD candidate and teaching fellow, Phil Fahn-Lai (S. Pierce Lab), used his background in graphic and web design to tackle the online challenges for students in OEB 126: Vertebrate Evolution. The course's labs involve hands-on observation of the MCZ's Vertebrate Paleontology collection. Determined to make the classroom experience meaningful for the remote students, Phil approached the Derek Bok Center's Learning Lab to design a custom web app for the course. In collaboration with members of the Pierce lab, Phil used photogrammetry to scan and create...
