2024 Winter Lecture Series: Smithsonian Bird Friendly Coffee and Cocoa: Proudly Serving Biodiversity with Melissa Mazurkewicz (February 4, 2024)

The Smithsonian Bird Friendly® certification is the environmental gold standard in sustainable food production for coffee and cocoa. Smithsonian scientists developed the Bird Friendly certification for coffee in the late 1990s to conserve habitat and protect migratory songbirds. Bird Friendly habitat ensures a mix of foliage cover, tree height and biodiversity that creates quality habitat for birds and other wildlife. Learn about how to eat, drink and live Bird Friendly!

Melissa Mazurkewicz is the Bird Friendly program manager for Latin America, where she manages the coffee and cocoa producer, auditor and extension components of the Smithsonian’s Bird Friendly certified supply chains. She has made Panama her home after serving in the Peace Corps 10 years ago. Marzurkewicz has a B.A. in horticulture from Pennsylvania State University and an M.A. in extension education from the University of Florida. Her love for native plants started during her internship at the Preserve in 2007.

All lectures will be held virtually using Zoom. They will be recorded and shared with everyone who registers for a short time. Zoom invitations will be sent out after this time to the email used to register for the event via education@bhwp.org.

Current status and research advances on beech leaf disease with Mihail Kantor, Ph.D. and Erika Consoli, Ph.D. (October 2, 2025)

Walking through the eastern forests, you may have noticed some striking characteristics of our American beech (Fagus grandifolia), including withered banded leaves. The presentation will provide an overview of the cause, a plant-parasitic nematode and the resulting beech leaf disease. It will cover current knowledge of dispersal mechanisms of the nematode causing the beech leaf disease. We will highlight plant-nematode interactions and outline the management strategies currently available for this disease.

Mihail Kantor, Ph.D, is an Assistant Research Professor of Nematology in the Department of Plant Pathology and Environmental Microbiology at Pennsylvania State University (Penn State). He established the Nematode Diagnostic Lab at Penn State, where he offers diagnostic services and stakeholder support against economically important plant-parasitic nematodes from soil and plant materials. Kantor’s research focus is the identification of plant-parasitic nematodes using systematics, morphology, and molecular techniques. In addition to nematode identification services, Kantor conducts research on different aspects of beech leaf disease, such as nematode dispersal and plant-nematode interactions.
Erika Consoli, PhD, is a Postdoctoral Scholar in the Kantor Nematology Lab at Penn State University. She’s an agronomist specialized in nematology, with experience working with both plant-parasitic and beneficial nematodes across diverse agricultural systems. She joined the Kantor Lab in April 2025 and is currently investigating the biocontrol potential of bacterial antagonists against Litylenchus crenatae mccannii (LCM), the causal agent of beech leaf disease.
