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.

A phylogenetic perspective on diversity of Galatheoidea (Munida, Munidopsis) from cold-water coral and cold seep communities in the western North Atlantic Ocean
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 nine species of Munidopsis from cold-water...

Low incidence of clonality in cold water corals revealed through the novel use of standardized protocol adapted to deep sea sampling
Sampling in the deep sea is a technical challenge, which has hindered the acquisition of robust datasets that are necessary to determine the fine-grained biological patterns and processes that may shape genetic diversity. Estimates of the extent of clonality in deep-sea species, despite the importance of clonality in shaping the local dynamics and evolutionary trajectories, have been...

Development of twelve microsatellite loci in the red tree corals Primnoa resedaeformis and Primnoa pacifica
A suite of tetra-, penta-, and hexa-nucleotide microsatellite loci were developed from Roche 454 pyrosequencing data for the cold-water octocorals Primnoa resedaeformis and P. pacifica. Twelve of 98 primer sets tested consistently amplified in 30 P. resedaeformis samples from Baltimore Canyon (western North Atlantic Ocean) and in 24 P. pacifica samples (Shutter Ridge, eastern Gulf of...

Testing the depth-differentiation hypothesis in a deepwater octocoral
The depth-differentiation hypothesis proposes that the bathyal region is a source of genetic diversity and an area where there is a high rate of species formation. Genetic differentiation should thus occur over relatively small vertical distances, particularly along the upper continental slope (200–1000 m) where oceanography varies greatly over small differences in depth. To test whether...

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...

Population connectivity of deep-sea corals
Identifying the scale of dispersal among habitats has been a challenge in marine ecology for decades (Grantham et al., 2003; Kinlan & Gaines, 2003; Hixon, 2011). Unlike terrestrial habitats in which barriers to dispersal may be obvious (e.g. mountain ranges, rivers), few absolute barriers to dispersal are recognizable in the sea. Additionally, most marine species have complex life cycles...

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...

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...

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...

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...
