Abbie Clasgens, BS, currently serves as a Macroinvertebrate Taxonomist in the Aquatic Biology Lab and has worked with EnviroScience since May 2023. In the lab, Abbie focuses on sorting and identifying macroinvertebrate samples for a variety of projects. While in the field, she has assisted with both quantitative and qualitative macroinvertebrate samples.

Abbie earned a Bachelor of Science degree in Wildlife and Fisheries Resources with a minor in Conservation Ecology at West Virginia University in Morgantown, WV. Throughout her time at WVU, she assisted with macroinvertebrate identification and curation for a variety of projects with habitats ranging from degraded urban streams to wetlands to small, high-elevation trout streams. Additionally, she worked in the WVU Big River Initiative Lab, where she collected and sorted larval fish samples from the Ohio River to monitor the spread of invasive carp. In her last year of school, Abbie served as the president of WVU’s student subchapter of the American Fisheries Society.

Abbie holds taxonomic certifications through the Society of Freshwater Science (SFS) for Eastern Ephemeroptera, Plecoptera, & Trichoptera (EPT) and Eastern General Arthropods. She holds a boater safety certification through the National Association of State Boating Law Administrators (NASBLA), and she is working on obtaining QHEI and HHEI certifications through the Ohio Environmental Protection Agency.

Before her time at West Virginia University, Abbie spent four years as a whitewater rafting guide on the New and Gauley Rivers in WV, where she discovered her love of aquatic insects and water conservation. In addition to guiding, Abbie also paddled competitively both nationally and internationally with the USA Raft Team. When she’s not working, Abbie enjoys paddling, fly fishing, and exploring trails around the area either by foot or by bike.

Kyle Scotese, Aquatic Biologist and Algal Taxonomist, is a skilled phycologist with over 15 years of experience enumerating algae and bacteria from marine and freshwater habitats. He holds two taxonomic certifications in diatom identification from the Society for Freshwater Science and has performed a variety of microscopic techniques. He also specializes in microscopic detection of potentially toxigenic microbes, including cyanobacteria and dinoflagellates. Kyle has been a valued member of the EnviroScience Aquatic Biology Laboratory since 2022.

Kyle has trained multiple phycologists to process algal samples accurately and efficiently in a production laboratory setting. He has led teams of algal taxonomists on large-scale monitoring projects for multiple agencies, including the 2012 and 2017 USEPA National Lakes Assessments and the 2015 USEPA National Wetlands Condition Assessment. Kyle has contributed to numerous scientific research publications describing the relationships between algae and their environments.

Kyle earned a Bachelor of Science in Biology at John Carroll University in 2005 and a Master of Science in Environmental Science from Cleveland State University in 2009. His education focused on anatomy and physiology, algal identification, aquatic biology, paleolimnology, and ecology. Before joining EnviroScience, Kyle worked as a phycologist for two top-ranked environmental consulting firms. He also served as President of his own small consulting business, Chagrin River Algae Limited, for three years.

Growing up on the shores of Lake Erie in Northeast Ohio, Kyle developed an early appreciation for water resources and a deep fascination with aquatic biology. Now living in Chagrin Falls with a first-order tributary of the Chagrin River in his backyard, he likes to explore and catalog the microbial inhabitants of the surface waters around his village as a passion project in his free time. He hopes to educate the public by sharing interesting photographs and descriptions of algae and highlighting issues that directly impact human health, such as harmful algal blooms and water fouling.

Recently, Kyle has identified and described a new freshwater species of diatom from the genus Stauroneis collected within Stebbins Gulch, a protected natural area managed by the Holden Arboretum in Kirtland, Ohio. This discovery will be published in a scientific journal and a local diatom voucher flora. It has inspired Kyle to explore other unresearched habitats in search of new and fascinating organisms.
