Arboretum Celebrates 25 Years of Research, Renames Science Facility


The Holden Arboretum celebrated the 25th anniversary of its research building with a ceremony rename the facility that houses the research program the Ellen Corning Long and T. Dixon Long Center for Plant and Environmental Science. Both T. Dixon Long and his late wife, Ellen Corning Long, were long-time supporters of the Arboretum and its research program. T. Dixon Long was a member of the Arboretum's board of directors from 1971 until 2003, serving as board president from 1982 until 1991. He is credited with leading the board through its most turbulent years from 1982 until the maturation of the Holden Trust in 1988 an played a large role in the creation of the science facility at Holden.


His wife's connection with the Arboretum began when her family built Lantern Court in the 1930s, and her parents, Warren H. and Maud Corning, took an interest in the arboretum. Corning served as the Arboretum's director on a volunteer basis, helping the Arboretum acquire new property and grow in its early years. Corning Long's work as an educator, biologist and botanist is honored by the research departments dedication to environmental sciences, as well as the scientists commitment to wringing with interns.

Plant and Microbial Ecology Summer 2016 Internship at The Holden Arboretum

This 12-week summer internship will provide you with an opportunity to work with scientists from The Holden Arboretum studying the effects of environmental change on plants and forests of Northeast Ohio. Internships typically run from late May through early August, but timing is flexible.


Duties may include: assisting in soil and plant sampling, plant data collection, as well as extracting, amplifying, and analyzing DNA from soils and roots. Interns will be compensated with a stipend of $400/week and on-site housing is available if needed for a nominal fee ($30 per week). Due to our rural location, interns are responsible for their own transportation.


Persons with knowledge of or interest in ecology, microbiology, and plant biology are encouraged to apply. Applicants should send a letter of interest, a resume that discusses your prior experience, and two references. Applicants should also indicate their primary research interest. Holden research staff and a description of their respective programs can be found at online by clicking here. Questions concerning the internships can be addressed to Dr. David Burke (


Review of applications begins immediately and continues until the positions are filled. Qualified applicants should submit a resume online. Apply here.

Holden Scientists award funds to organize international conference on plant water transport.


A proposal for a new conference on multiscale plant vascular biology submitted by Arboretum scientist Juliana Medeiros (conference co-chairperson) and collaborators William Pickman (conference chairman, University of New Mexico) and Barbara Lachenbruch (conference vice-chairperson, Oregon State University) has been accepted as a Gordon Research Conference-sponsored meeting. Gordan Research Conferences (GRC) is a non-profit organization dedicated to providing support for international conferences that cover topics on the frontiers of research in the biological, chemical and physical sciences. GRC meetings are small, fewer than 200 people, but they cover very specific subfields of research and are considered premier conferences for networking and collaboration. Proposals for new conferences are highly competitive, and the GRC Board of Trustees approves only a few new conferences each year. The conference will bring together scientists working at all scales of plant water transport research. The meeting will take place in the summer of 2016 and pending positive outcomes of the conference, it may be promoted to an official biannual Gordan Research Conference. Advances in plant water transport are of critical importance for understanding how plants may respond to global climate change.
