January 4, 2018 PhysFest2 is coming to Holden Arboretum
July 15-19, 2018. This event will provide graduate student training in
ecophysiology techniques, create a data set on canopy physiology using the
canopy walk and emergent tower at Holden, and provide training on scientific
communication for the public. For more information check out the PHYSFEST2 website
September 6, 2017 Welcome new graduate student Samia Hamati
to the lab. Ms. Hamati will be jointly advised by Dr. Medeiros and Dr. David
Ward, the KSU Art and Margaret Herrick Endowed Professor of Plant Biology.
Samia will study how environmental factors such as competition for light affect
growth and physiological stress tolerance in the evergreen shrub Juniperus
virginiana, and how this relates to the recent expansion of the species
range into mid-western grassland ecosystems.
August 3, 2017 A Rhododendron Research Network has been
established in conjunction with the American Rhododendron Society. Dr. Juliana
Medeiros and colleague Dr. Erik Nilsen (Virginia Tech) will lead the network,
