Latest Newsletter Released by the Rhododendron Research Network

Read the latest news in Rhododendron research in the July 2020 edition of the Rhododendron Research Network Newsletter (found here). This network, led by Holden Scientist Dr. Juliana Medeiros and Dr. Erik Nilsen of Virginia Tech University, has attracted and connected prominent researchers from around the globe for collaborative projects, including researchers in China, the US, Canada, India, Japan, the UK and Germany, and connected them with community science volunteers based both in the American Rhododendron Society and at Holden. Please visit http://rhodo-research.net to learn more about how the Rhododendron Research Network is advancing Rhododendron horticulture, research and conservation, and increasing awareness of genus Rhododendron as one of Earth’s biodiversity treasures.

David Burke and Adam Hoke Co-Authored a Study on Beech Leaf Disease

The Burke lab is continuing research on beech leaf disease and had another paper published. This paper was led by Sharon Reed who is with the Ontario Ministry of Natural Resources and Forestry. David Burke and Adam Hoke are co-authors on the study, as we contributed data from Holden’s lower Baldwin research plots on nematode population size. This paper appeared in Forest Pathology and can be found here.

Katie Stuble is a Co-Author on a Study Published in the Journal Ecology

Katie Stuble co-authored a paper titled “Year effects: Inter-annual variation as a driver of community assembly dynamics” for the journal Ecology. The published study explores the substantial, but rarely acknowledged, impacts of interannual variability on the outcomes of community assembly (the process by which new plant communities come together). You can read the article here.

The Research Department Welcomes Summer Interns

Holden’s Research Department is hosting local students for our summer intern program. Due to COVID-19, the majority of our summer research is being conducted in the field and in a socially-distant manner. The summer research projects range in topics that include the Malus apple microbiome, forest restoration, phenology of spring ephemerals, tree response to their urban environment, and the expansion of red cedar range.

Holden Researchers Participate in Climate Change Webinar

Holden’s Rhododendron Collections Manager, Connor Ryan, and Research Associate, Sarah Kyker, participated in a webinar run by Oberlin College. The webinar presented information about the significance of trees and forests in our daily lives and in the broader context of climate change. Holden researchers joined individuals from the Luce Initiative on Asian Studies and the Environment (LIASE), as well as the Departments of Environmental Studies, Biology, East Asian Studies, and Geology at Oberlin College to discuss the importance of trees and climate change. A recording of the webinar can be viewed here.

The Medeiros Lab Welcomes Randy Long

The Medeiros Lab at Holden Arboretum welcomed new postdoctoral researcher Dr. Randy Long, who will work on a project funded by the National Science Foundation examining the physiology of Eastern Red Cedar (Juniperus virginiana). This interdisciplinary project is being conducted in collaboration with researchers at three local universities, Kent State, Ohio State and Denison, to better understand the relative importance of factors like climate, seed dispersal and fire regime in driving the westward range expansion of this long-lived woody shrub into grassland ecosystems.

New Study on Planting Order during Restoration published by Katie Stuble

Holden scientist Katie Stuble published a new paper in the journal Diversity, exploring the impacts of planting order on restoration outcomes. Planting species early on in restoration can be used to promote target species. However, Stuble’s research found that, in some cases, planting restoration species at different times, as opposed to all at once, can leave restored areas vulnerable to invasion by non-native species. This suggests that, in some cases, establishment of non-native species may be an unintended consequence of using such staggered plantings of species as a restoration tool. The article is available here.

David Burke Gives Webinar on Beech Leaf Disease

David Burke, Holden’s Vice President for Science and Conservation, gave a webinar on his lab’s research on beech leaf disease (BLD). This two-part webinar began with Dan Volk of the Cleveland Metroparks first giving information about BLD. David provided content for the second half and discussed current data from his lab that are helping to find the cause of BLD. The webinar was hosted by the Emerald Ash Borer (EAB) University, which is a collaborative project between Purdue University, Michigan State University, and The Ohio State University that originally distributed information on emerald ash borer. More recently, EAB University has expanded their scope to distribute information on more pests and diseases. Check out the webinar here.

Research from Holden on Beech Leaf Disease Published in Forest Pathology

Two of Holden’s researchers, David Burke (Vice President for Science and Conservation) and Adam Hoke (Research Specialist), were co-authors on articles about beech leaf disease (BLD) that were published by Forest Pathology. One article (found here) details the leaf microbiome on symptomatic and asymtomatic leaves and buds and identifies bacterial taxa that are more commonly associated with infected leaves. The other article (found here) describes the association of infected beech trees with the nematode species Litylenchus crenatae mccannii, a subspecies of L. crenatae, which were originally described in Japan. This newly described subspecies is currently believed to be necessary for disease symptoms.

Holden Research Welcomes Na Wei

The Research Department is excited to welcome our new staff Scientist, Dr. Na Wei. Wei’s research investigates the ecological and evolutionary mechanisms that confer plant adaptation to the environment and focuses on the interactions between plant phenotype, genotype, and environment. More information about Na’s research can be found here.
