After earning his undergraduate degree in plant biology from the University of Vermont, Jacob spent time studying the phylogenetics of lycophytes at the Smithsonian Institution’s National Museum of Natural History. As a PhD student in the department of Organismic and Evolutionary Biology, he plans to delve into research focusing on morphological development and diversification in a phylogenetic context.
The Arboretum’s 2017 plant anatomy summer short course kicks off at the Weld Hill research facility.
Congratulations Dr. Povilus!
The early evolution of flowers remains something of a mystery. As part of her Master’s research, Kristel Schoonderwoerd, PhD Candidate in the Friedman Lab, joined a large international team to reconstruct the ancestral flower based on DNA and floral characteristics of known flowers. The results are published in Nature Communications.
Jack will study bud development in Picrasma quassioides during his time at Weld Hill. Welcome Jack!
This species has weathered millions of years of changing environmental conditions, and despite its early origins, is the sole remaining species of its family, Austrobaileyaceae. A recent expedition and accompanying study by Ned Friedman, Juan Losada and Julien Bachelier examined prolonged embryo development in this extraordinary species.
“Plant Anatomy 2015: Development, function and evolution”, the summer course sponsored by the Arnold Arboretum and microMORPH, was featured in the newsletter of the International Association of Wood Anatomists Journal. (pdf)
Well done, Becky!
They found that there was a precise window of time, marked by specific secretory proteins, in which the stigma (female) was receptive to the pollen (male). This work was published in American Journal of Botany. (abstract)
Arboretum class explores science as Darwin did, in an example of College’s commitment to new ways of learning.
In gleaming new Arboretum lab, researchers still use 1931 device because it’s the best there is.
Arboretum offers increasingly rare course in their morphology.
Arboretum’s Friedman follows development of life along green line.
