Advancing the Environmental DNA Toolkit for Ecosystem Monitoring and Management
The emerging field of Environmental DNA (eDNA) analysis allows characterization of species presence and community biodiversity by identifying trace amounts of genetic material left behind as organisms move through their environments. EESC scientists have been using eDNA technologies to detect native and rare species and as community biomonitoring tools.
RADSeq Data to assess population structure of Desmophyllum pertusum found along the United States eastern continental margin
This dataset contains metadata about the origin of the cold-water coral samples that were RAD sequenced and the single nucleotide polymorphism (SNPs) generated for population genomic analyses. These data were used to examine patterns of genomic structure of Desmophyllum pertusum from throughout US waters along the eastern continental margin and the Gulf of Mexico. The raw sequence data...
Oceanographic conditions at Richardson reef reveal new suitable habitat for cold-water corals
Cold-water corals create complex structures, but our incomplete knowledge of their niche space limits our ability to understand their distribution and therefore the impact of the ecosystem services they provide in the ocean. The Richardson reef complex consists of over 150 km of linear reef tracts within an area of 75 km2 between 700-900 m depth. This reef experiences rapid shifts in...
Population structure of Desmophyllum pertusum found along the United States eastern continental margin
ObjectiveThe connectivity and genetic structuring of populations throughout a region influence a species’ resilience and probability of recovery from anthropogenic impacts. By gaining a comprehensive understanding of population connectivity, more effective management can be prioritized. To assess the connectivity and population genetic structure of a common cold-water coral species...

Expanding our view of the cold-water coral niche and accounting of the ecosystem services of the reef habitat
Coral reefs are iconic ecosystems that support diverse, productive communities in both shallow and deep waters. However, our incomplete knowledge of cold-water coral (CWC) niche space limits our understanding of their distribution and precludes a complete accounting of the ecosystem services they provide. Here, we present the results of recent surveys of the CWC mound province on the...
