Creator:: Jackson, Tyler M. and O’Malley, Kathleen G.
Abstract:: Understanding connectivity of marine organisms is necessary for determining the appropriate scale of conservation and management strategies. For species that inhabit both the coastal ocean and partially enclosed water bodies (i.e., estuaries or fjords), this information is even more critical since estuaries and fjords are often characterized by hydrological complexities...

Abstract:: Using a combination of population‐ and individual‐based analytical approaches, we provide a comprehensive examination of genetic connectivity of Dungeness crab (Cancer magister) along ~1,200 km of the California Current System (CCS). We sampled individuals at 33 sites in 2012 to establish a baseline of genetic diversity and hierarchal population genetic...

Abstract:: Limited approaches exist for studying population connectivity in widely dispersing marine benthic invertebrates. Genetic techniques can provide important insights toward identifying recruitment trajectories. Here, 10 microsatellite loci were used to examine connectivity among Oregon Dungeness crabs (Cancer magister, Dana, 1852) in the California Current System (CCS) (n = 801) as...

Creator:: Lee, Elizabeth M. J. and O'Malley, Kathleen G.
Abstract:: Dynamic marine environments can shape complex spatial and temporal patterns in the population connectivity of marine species, and this is often exemplified in species with long larval phases. Here, we used a genotyping-by-sequencing (GBS) approach to examine fine-scale spatial and temporal genomic variation among Dungeness crab Cancer magister larval recruits...

Abstract:: Environmental history recorded in estuarine sediment describes water quality regimes through the use of geochemical and biological proxies. We collected sediment cores from two locations in the Coos Estuary, Oregon, at South Slough and Haynes Inlet, spanning from ~ 1680 AD to the present. To reconstruct the historical water column oxygen...

Abstract:: Impending shortages of high-quality aggregates in areas along the Oregon coast have forced users to search for new sources of supply. A number of feasible methods exist for supplying the affected areas. Three of these alternatives are: (1) importation, either by truck, rail, or barge; (2) the use of good-quality...

Creator:: Burchfield, Robert M., Hicks, Russel G., and Oregon State University. Sea Grant Marine Advisory Program
Abstract:: The task of obtaining good-quality aggregate for construction is a growing problem for most Oregon coastal communities. Current shortages have forced users to import quality aggregate from areas as far as the Willamette Valley. The practice of transporting aggregate over such long distances is both costly and energy-intensive. One feasible...

Creator:: Burchfield, Robert M., Hicks, Russel G., and Oregon State University. Sea Grant Marine Advisory Program
Abstract:: The natural reserves of high quality construction aggregates found along the Oregon coast are being depleted. The impending shortages are compounded by restrictions being placed on existing aggregate sources because of energy. economic, and environmental considerations, and zoning regulations. A current solution for the shortage is to import quality aggregate...

Abstract:: For many historical and contemporary experimental studies in marine biology, seawater carbonate chemistry remains a ghost factor, an uncontrolled, unmeasured, and often dynamic variable affecting experimental organisms or the treatments to which investigators subject them. We highlight how environmental variability, such as seasonal upwelling and biological respiration, drive variation in...

Abstract:: Fisheries-related mortality has been influential in driving global declines in seabird populations. Understanding the overlap between seabird distribution and fisheries is one important element in assessing bycatch risk, and may be achieved by tracking the movements of individual birds and fishing vessels. Here, we assess the spatiotemporal overlap between the...
