Cheryl L Morrison, Ph.D.
Cheryl Morrison is a Research Geneticist at the USGS Eastern Ecological Science Center, National Fish Health Laboratory in Kearneysville, WV
Intro
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.

Nine microsatellite loci developed from the octocoral, Paragorgia arborea
Paragorgia arborea, or bubblegum coral, occurs in continental slope habitats worldwide, which are increasingly threatened by human activities such as energy development and fisheries practices. From 101 putative loci screened, nine microsatellite markers were developed from samples taken from Baltimore canyon in the western North Atlantic Ocean. The number of alleles ranged from two to thirteen pe

Acute survivorship of the deep-sea coral Lophelia pertusa from the Gulf of Mexico under acidification, warming, and deoxygenation
Changing global climate due to anthropogenic emissions of CO2 are driving rapid changes in the physical and chemical environment of the oceans via warming, deoxygenation, and acidification. These changes may threaten the persistence of species and populations across a range of latitudes and depths, including species that support diverse biological communities that in turn provide ecological stabil

Development of ten microsatellite loci in the invasive giant African land snail, Achatina (=Lissachatina) fulica Bowdich, 1822
A suite of tetra-nucleotide microsatellite loci were developed for the invasive giant African land snail, Achatina (=Lissachatina) fulica Bowdich, 1822, from Ion Torrent next-generation sequencing data. Ten of the 96 primer sets tested amplified consistently in 30 snails from Miami, Florida, plus 12 individuals representative of their native East Africa, Indian and Pacific Ocean regions. The loci

Development of eighteen microsatellite loci in walleye (Sander vitreus)
A suite of tri- and tetra-nucleotide microsatellite loci were developed for walleye (Sander vitreus) from 454 pyrosequencing data. Eighteen of the 50 primer sets tested amplified consistently in 35 walleye from two lakes on Isle Royale, Lake Superior: Chickenbone Lake and Whittlesey Lake. The loci displayed moderate levels of allelic diversity (average 5.5 alleles/locus) and heterozygosity (averag

Global ocean conveyor lowers extinction risk in the deep sea
General paradigms of species extinction risk are urgently needed as global habitat loss and rapid climate change threaten Earth with what could be its sixth mass extinction. Using the stony coral Lophelia pertusa as a model organism with the potential for wide larval dispersal, we investigated how the global ocean conveyor drove an unprecedented post-glacial range expansion in Earth׳s largest biom

Self-recognition in corals facilitates deep-sea habitat engineering
The ability of coral reefs to engineer complex three-dimensional habitats is central to their success and the rich biodiversity they support. In tropical reefs, encrusting coralline algae bind together substrates and dead coral framework to make continuous reef structures, but beyond the photic zone, the cold-water coral Lophelia pertusa also forms large biogenic reefs, facilitated by skeletal fus

Genetic discontinuity among regional populations of Lophelia pertusa in the North Atlantic 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 ability or population connectivity in Lophelia pertusa, the dominant framework-forming coral on the continental slope in the North Atlantic Ocean. Using nine microsatellite DNA markers, we assessed the spatial scale and pattern of gen

Characterization of 13 microsatellite loci for the deep-sea coral, Lophelia pertusa (Linnaeus 1758), from the western North Atlantic Ocean and Gulf of Mexico
A suite of 13 polymorphic tri- and tetranucleotide microsatellite loci were isolated from the ahermatypic deep-sea coral, Lophelia pertusa. Among 51 individuals collected from three disjunct oceanic regions, allelic diversity ranged from six to 38 alleles and averaged 9.1 alleles per locus. Observed heterozygosity ranged from 9.1 to 96.8% and averaged 62.3% in the Gulf of Mexico population. For so

Exploration of the deep Gulf of Mexico slope using DSV Alvin: Site selection and geologic character
The Gulf of Mexico is well known for its hydrocarbon seeps, associated chemosynthetic communities, and gas hydrates. However, most direct observations and samplings of seep sites have been concentrated above water depths of approximately 3000 ft (1000 m) because of the scarcity of deep diving manned submersibles.
