Cheryl L Morrison, Ph.D.
Biography
Intro
Cheryl Morrison is a Research Geneticist at the USGS Leetown Science Center, National Fish Health Laboratory in the Eastern Panhandle of WV. Cheryl received a B.S. degree in Marine Biology from the University of North Carolina at Wilmington (1991) and her Ph.D. in Biological Sciences from Florida State University (1997). Since joining the USGS in 2002, her research has involved the application of conservation genetics and genomics techniques to species at risk. Cheryl has worked on a variety of species from aquatic habitats such as freshwater rivers (Atlantic salmon, darters and mussels), and vulnerable deep-sea ecosystems on the U.S. continental slope (deep-sea corals, cold seeps and canyons). Such deep-sea ecosystems remain poorly characterized yet are vulnerable to natural and anthropogenic disturbances. Studies of genetic connectivity among populations of dominant, habitat-forming coral species inform marine spatial planning for effective stewardship of natural resources.
Education
- Ph.D. 1997, Florida State University
- B.S., 1991, University of North Carolina, Wilmington, Major: Marine Biology
Current Position
Dr. Morrison is a principal investigator for multiple studies that aim to describe biodiversity, assess taxonomic status, define units of conservation, and determine dispersal pathways of marine invertebrates and invasive species. A focus of Dr. Morrison’s research has been the description of biodiversity and connectivity in vulnerable deep-sea ecosystems on the U.S. continental slope. Such ecosystems remain poorly characterized, yet are vulnerable to natural and anthropogenic disturbances. Studies of genetic connectivity among populations of dominant, habitat-forming coral species may inform marine spatial planning for effective stewardship of natural resources.

USGS Role in DEEP SEARCH: Deep Sea Exploration to Advance Research on Coral, Canyon, and Cold-seep Habitats
USGS scientists are collaborating with multiple agencies to provide the esssential foundation for understanding these deep-sea environments.

DISCOVRE (DIversity, Systematics and COnnectivity of Vulnerable Reef Ecosystems) is an integrated, multidisciplinary, international effort investigating the unique and fragile deep-sea coral environments from the microscopic level to the ecosystem level.
Genetic connectivity among regional populations of red tree corals (Primnoa pacifica) in the North Pacific Ocean
Knowledge of the degree to which populations are connected through larval dispersal is imperative to effective management, yet little is known about larval dispersal capability or population connectivity in Primnoa pacifica, an important habitat forming octocoral on the outer continental shelf and upper slope in the Gulf of Alaska. Red tree corals can reach massive size (up to 5m...
Conservation Genetics and Genomics of the Narrowly Endemic Island Marble Butterfly Euchloe ausonides insulanus
The island marble butterfly (Euchloe ausonides insulanus) was first discovered on Vancouver Island, Canada in 1861. Based on morphological characteristics, it has been described as a subspecies of Euchloe ausonides. After a collection was made in 1908 on Gabriola Island, Canada, the island marble was not seen again until 1998 on San Juan Island, Washington, USA. Recent...
Genetic characterization of the clubshell species complex (Pleurobema clava and P. oviforme) for enhanced conservation
The diversity of freshwater mussels (family Unionidae) in the United States is unmatched in the rest of the world, yet this biodiversity is highly vulnerable, with more than 70% of recognized species considered to be either endangered, threatened, or of special concern. Most species inhabit limited ranges and have small (and/or often unknown) dispersal abilities due to reliance on specific...
Deepwater Atlantic Habitats II: Continued Atlantic Research and Exploration in Deepwater Ecosystems with Focus on Coral, Canyon, and Seep Communities. Part II: Genetic Connectivity and Oceanomic Studies
This study utilizes genetics and genomics techniques to characterize biodiversity and genetic connectivity among deep-sea coral habitats and cold seeps in and near submarine canyons and will use environmental DNA techniques to characterize plankton diversity and to identify key contributors to carbon export from surface waters that sustain sensitive benthic communities. The proposed genetics...
Deep-Sea Coral Ecosystems
Although out of sight to most, a diverse array of coral species thrive deep below the photic zone off U.S. coasts and worldwide. Deep-sea corals can be found at depths greater than 50m, where sunlight does not penetrate. Similar to shallow-water corals, larger sea fan and reef-forming deep-sea coral species create structural complexity in the deep sea, attracting fishes and invertebrates that...
Phenotypic plasticity or a reproductive dead end? Primnoa pacifica (Cnidaria: Alcyonacea) in the southeastern Alaska region
Red tree corals (Primnoa pacifica) are abundant in the eastern Gulf of Alaska, from the glacial fjords of Southeast Alaska where they emerge to as shallow as 6 m, to the continental shelf edge and seamounts where they are more commonly found at depths greater than 150 – 500 m. This keystone species forms large thickets, creating habitat for many...

Sautter, Leslie R; Morrison, Cheryl L.; Cantwell, Kasey; Sowers, Derek; Lobecker, ElizabethMolecular characterization of Bathymodiolus mussels and gill symbionts associated with chemosynthetic habitats from the U.S. Atlantic margin
Mussels of the genus Bathymodiolus are among the most widespread colonizers of hydrothermal vent and cold seep environments, sustained by endosymbiosis with chemosynthetic bacteria. Presumed species of Bathymodiolus are abundant at newly discovered cold seeps on the Mid-Atlantic continental slope, however morphological taxonomy is challenging, and...

J.; Morrison, Cheryl L.The complete maternal mitochondrial genome sequences of two imperiled North American freshwater mussels: Alasmidonta heterodon and Alasmidonta varicosa (Bivalvia: Unionoida: Unionidae)
The freshwater mussels Alasmidonta heterodon and A. varicosa historically inhabited rivers along the North American Atlantic coast from the Carolinas, U.S.A., to New Brunswick, CA. However, many populations have been extirpated, and A. heterodon is now federally listed in the U.S.A. as endangered, and both A....

Cold-water corals provide critical habitats for a multitude of marine species, but are understudied relative to tropical corals. Primnoa pacifica is a cold-water coral prevalent throughout Alaskan waters, while another species in the genus, Primnoa resedaeformis, is widely distributed in the Atlantic Ocean. This study examined the...

Chelonid alphaherpesvirus 5 (ChHV5) is a herpesvirus associated with fibropapillomatosis (FP) in sea turtles worldwide. Single-locus typing has previously shown differentiation between Atlantic and Pacific strains of this virus, with low variation within each geographic clade. However, a lack of multi-locus genomic sequence data hinders...

The Pleurobemini (Bivalvia: Unionida) represent approximately one-third of freshwater mussel diversity in North America. Species identification within this group is challenging due to morphological convergence and phenotypic plasticity. Accurate species identification, including characterisation of currently unrecognised taxa, is required to...

Deep-sea coral and sponge ecosystems are widespread throughout most of Alaska’s marine waters. In some places, such as the central and western Aleutian Islands, deep-sea coral and sponge resources can be extremely diverse and may rank among the most abundant deep-sea coral and sponge communities in the world. Many different species of fishes and...

Squat lobsters (Galatheoidea and Chirostyloidea), a diverse group of decapod crustaceans, are ubiquitous members of the deep-sea fauna. Within Galatheoidea, the genera Munida and Munidopsis are the most diverse, but accurate estimates of biodiversity are difficult due to morphological complexity and cryptic diversity. Four species of Munida and...
