The Science Lab/ Kitchen Overlap
By Sharon Halkovics, Research Specialist
Years ago, I completed my undergraduate studies earning a bachelor’s degree in Environmental Health Science. I started down my career path assisting in a lab at a university. A couple of years later, I veered off course for a more hands-in-the-dirt experience and fell in love with small-scale farming. Farming led to working in restaurant kitchens then a culinary school, which eventually led to freelancing as a food stylist on large commercial accounts.

A Morning in Working Woods
By Emma Dawson- Glass, Research Specialist
Have you ever wondered what the day-to-day of scientists looks like? Certainly, daily activities will vary greatly depending on what kind of scientist you are, what time of year it is, and where you work. For community ecologists in the Stuble Lab at the Holden Arboretum, the summer months means it’s time to get out into the natural area at Holden to collect data.

A virtual tour of the natural areas used by the research department
By Emma Dawson-Glass, Research Specialist
Beyond its curated collections, the Holden Arboretum also retains many natural areas. In fact, most of the Holden Arboretum property is made up of natural areas, with 3,000 acres out of a total of 3,600 acres of the Arboretum property being made up of natural areas. These natural areas are a vital resource to researchers and allows us to study a wide breadth of Northeast Ohio habitats. In these natural areas we study everything from community assembly, to responses to restoration and management, to the impacts of global change disturbances such as climate change, invasive species, acid rain, and novel diseases. Below, we highlight a few of the many natural area field sites that scientists in the Research Department use for study.

New Eastern Hemlock Conservation Work Kicks Off at Holden
By Rachel Kappler, Great Lakes Basin Forest Health Collaborative (GLB FHC) Coordinator
Researchers across the country are interested in learning more about forest pests that threaten our native tree species. Populations of eastern hemlock, found across Appalachia, New England, and the Great Lakes, are faced with two different insect pests, hemlock woolly adelgid and elongate hemlock scale, that have killed nearly 80 percent of hemlocks in some areas.

A Virtual Tour of the Collections used by the Research Department
By Emma Dawson-Glass, Research Specialist
One of the greatest benefits of being a researcher at an arboretum is being able to access curated plant collections. Often, these collections have a well recorded history and can be sourced from all over the world. As such, researchers can ask many questions about plants, ranging from their evolutionary adaptions to their future responses to novel global change threats (like disease and climate change). Here, we highlight some of the collections at the Holden Arboretum that scientists in the Research Department use for study.

The Spring Ephemerals in Stebbins Gulch
By Sarah R. Carrino-Kyker, Postdoctoral Research Associate
Spring ephemeral flowers in the forest only bloom for a short period of time after the weather warms up from the winter, but before the trees in the canopy fully leaf-out and the light levels get lower on the forest floor. As such, our days of flower surveys are often long days in the field crammed together all in one or two weeks. This way, we can catch the plants before they go dormant again. But, these days of flower surveys are also ones when I have experienced some of the best natural beauty of the forests at Holden!

How to Clone a Tree
By Rachel Kappler, Great Lakes Basin Forest Health Collaborative (GLB FHC) Coordinator
How do you study a fully grown tree in a regular-sized laboratory? You collect a branch, take it back to the lab, graft it onto a much smaller tree, and study the clone. And that’s exactly what Holden researchers are doing with beech trees from all over the Great Lakes Basin. They’re making these clones because some trees from the region appear to be resistant to pests that cause beech leaf disease, and they want to understand why.

New Research Collaboration Aims to Save Eastern Hemlocks
By Rachel Kappler, Great Lakes Basin Forest Health Collaborative (GLB FHC) Coordinator
Holden research launched a new initiative this year to help conserve eastern hemlocks. The Great Lakes Basin Forest Health Collaborative (GLB FHC) brings together the US Forest Service Northern Research Station in Ohio and the New Jersey Forest Service with Holden to focus on breeding eastern hemlock trees for resistance to pests.

Alexa Wagner Awarded a Phipps Botany in Action Fellowship
Holden Ph.D. Candidate, Alexa Wagner, has been awarded a Botany in Action Fellowship from Phipps Conservatory for her research in Working Woods. The title of her proposal is “Understanding the impacts of forest restoration on demographic shifts in the understory plant community.” This is the third year of funding and her third year as a fellow. As a part of the fellowship position, Alexa will spend a week at Phipps to partake in science engagement activities including Phipps staff, local K-12 grade youth, and the general public. “I look forward to this opportunity to increase science awareness and practice my formal and informal science outreach skills,” Alexa said.

When an Ecologist is a Lab Rat
By Sarah Kyker, PhD, Postdoctoral Research Associate
What does the soil ecology lab at Holden have in common with a crime lab? More than you might think! In the soil ecology lab, we rely heavily on DNA sequences, just like crime labs. Crime labs use DNA sequences to match a suspect to a crime scene. We use DNA sequences to match species of fungi and bacteria to our forest soils. (Sidenote: We focus on bacteria and fungi in the soil because they are the most active decomposers!)

Behind-the-Scenes Spring Phenology Monitoring
By Emma Dawson-Glass, Research Specialist
Spring is underway here in Northeast Ohio, meaning it’s time for the Stuble lab and our team of wonderful volunteers to get out in Bole Woods and start monitoring spring phenology. For those unfamiliar, phenology is the study of the timing of natural phenomena as it relates to seasonal changes. In our case, we’re monitoring the phenology of spring ephemerals—the wildflowers that come up in forest understories during the spring while the canopy is still open.

A short tale about hemlock trees, bacteria and a nasty insect.
By David J. Burke, PhD, Vice President for Science and Conservation
Many of us love our native hemlock trees (Tsuga canadensis). They are beautiful, but more than that, they serve an important ecological role in many of our forests. Where they are found along streams and waterbodies, they cool the water and maintain cold water habitat necessary for many types of aquatic life. In addition, they are important bird habitat, and many moths and butterflies are found only (or mostly) in hemlock. Quick fact: Did you know that hemlock trees can live to be 550 years old? Amaze your friends!

Get to know a scientist: Connor Ryan
By Emma Dawson-Glass, Research Specialist
Where do plants come from? No, we’re not talking about the birds and the bees or the sun and the soil. Many of our favorite ornamental plants have been specifically engineered to have showier flowers, grow taller, and resist disease, creating plants with little resemblance to their wild relatives. Ever wonder who comes up with these things, and puts them into practice? This week we talk to Connor Ryan – the Rhododendron Collections Manager within Holden’s Research Department – on how he got into collections and plant breeding.

Evidence Based Gardening
By Connor Ryan, MS, Rhododendron Collections Manager
Lots of plants have problems in landscapes. Perhaps your Colorado spruce (Picea pungens) is losing all its lower leaves. Or your rhododendron’s stems keep dying. Or the leaves of your blueberry bush (Vaccinium) are completely yellow. How do you figure out what is causing the problem, and what is the solution? A common move for gardeners is to run to the local garden center, purchase fertilizer or a fungicide or an insecticide, and then use those products non-discriminately, praying that this will fix everything. While this can sometimes work, there resources for the average gardener to help address garden problems more effectively and sustainably.
