Can Dam Removal Restore Threatened Shorelines? The Elwha Case Study
(Friday Harbor Laboratories, 2-06-30)Dam construction on rivers like the Elwha River in Washington State reduces sediment supply to adjacent coastal systems and has often been linked to coastal erosion and threats to human infrastructure. With the removal of ... -
Growth in Some Laminariales
(1982-08-20)In the present study, I had two main objectives: First, to determine the rates, regions, and duration of elongation in a variety of kelps and, second, to compare the results obtained from use of the hole-punch and fluorescent ... -
Local variation among rocky subtidal habitats in the San Juan Archipelago: are differences in community structure associated with small-scale changes in abiotic factors?
(2011)Previous studies have demonstrated that regional variation in community structure is largely driven by abiotic factors, but that these factors have less influence on community structure at smaller scales. We sought to ... -
Physical Factors Affecting the Abundance and Distribution of the Pacific Sand Lance Ammodytes hexapterus in the San Juan Archipelago
(2011)Anecdotal evidence has suggested in the past that the Pacific Sand Lance, Ammodytes hexapterus is present every other year in the San Juan Archipelago. This study found the fish to be present in the San Juans, as they were ... -
Surf’s up! The energetic costs of labriform swimming in unsteady flows
(2011)Swimming represents the primary means through which fishes interact with their environment, and factors influencing swimming performance can profoundly affect their distribution and survivorship. Traditional measures of ... -
Predation techniques used by the Red Rock Crab Cancer productus on Marine Gastropods of varying shell length
(2011)Relationships between shell thickness and predation techniques have been established; however, it has not yet been determined if a relationship exists between shell length and predation technique. Crabs often use a variety ... -
Comparison of Diet of Chlamys hastata and Chlamys rubida from Shallow and Deep Waters off the San Juan Islands
(2011)Gut contents of two species of sea scallops, Chlamys rubida and C. hastata, were compared for individuals from the San Juan Channel collected in shallow (20m) and deep (~80m) habitats. Gut contents were preserved in ... -
Prairie Restoration: An Interdisciplinary Approach
(2011)Invasions of nonnative species are a major problem for environments around the world, and interest in restoring the rare prairie ecosystem in Washington has been growing since the 1980s. The majority of the research in ... -
Documenting the effect of substrate angle on invertebrate assembly patterns: An approach for identifying sessile benthic invertebrate assemblages in the San Juan Channel rocky subtidal zone
(2011)Understanding benthic community distributions, and using such information in marine restoration ecology, requires an understanding of the effect of substrate angle on assembly patterns. To date, there is no information ...
