Assistant Curator, Botany
Co-chair of Collections

Biography
Mason Heberling is the assistant curator in the Section of Botany and co-chair
of collections at Carnegie Museum of Natural History. Heberling received his
Ph.D. from Syracuse University in Biology in 2015, and a B.S. from Penn State
in Biology (Ecology) in 2010. He conducted postdoctoral research through the
University of Tennessee Knoxville in the Department of Ecology and
Evolutionary Biology and in the Section of Botany at Carnegie Museum of
Natural History.
Heberling is a plant ecologist and botanist whose research explores plant
functional strategies in deciduous forest understories, especially in the context
of environmental change. Much of his current research focuses on the ecology
and evolution of non-native, invasive plants in the eastern United States, the
ecophysiological strategies of the herbaceous layer in deciduous forests, and
the impacts of climate change on the timing of leafing out and flowering in
temperate deciduous forests.
Heberling is particularly interested in innovative uses for natural history
collections and rethinking how we collect. He has strong and diverse interests
in the longstanding and emerging roles of herbaria in the Anthropocene. He is
part of a long-term collaborative project in the Section of Botany to revisit sites
throughout Western Pennsylvania that were historically visited by previous
museum curators and botanists to study changes in our local flora and species’
responses to climate change.
