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 ... -
Can Dam Removal Restore Threatened Shorelines? The Elwha Case Study
(Friday Harbor Laboratories, 2014-06)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 ... -
Capture Efficiency of Various Species and Sizes of Drift Macrophytes by Red Urchins, Strongylocentrotus franciscanus
(Friday Harbor Laboratories, 2013-06)In the San Juan Islands, drift macrophytes from shallow waters represent a significant spatial subsidy provided to the subtidal zone. This organic matter is a potential food source for deep dwelling herbivores like the red ... -
Carbonate chemistry of the San Juan Archipelago: A baseline field study for future ocean acidification research
(Friday Harbor Labs, 2011-07)Natural variability in the carbonate system is difficult to control in the lab. Furthermore, environmental carbonate chemistry data over small spatial scales is lacking. We measured discrete water samples across various ... -
Changes in Marine Bird Population Composition and Abundances Over Spatial and Temporal Scales in the San Juan islands
(Friday Harbor Labs, 2011-09)Southern resident killer whales seasonally inhabit the Salish Sea waters of British Columbia and Washington and are unique in their feeding behavior. This endangered subpopulation is also a valued resource that has led ... -
Characteristics of echolocation clicks in southern resident killer whales (Orcinus orcas)
(Friday Harbor Labs, 2011-09)Odontocetes rely on echolocation clicks to navigate, forage and communicate. As such, understanding the characters of click shall help understanding whale communication. Southern resident killer whales of the North Pacific ... -
Characteristics of the Habitat of the Northern Clingfish
(Friday Harbor Laboratories, 2014-08-30)The Northern Clingfish, Gobiesox maeandricus, has many well-studied morphological adaptations to help it cope with the harsh environment that it lives in: the intertidal zone. Lab studies have shown that this fish can ... -
Characterization of the Habitat of Ammodytes hexapterus (Pacific Sand Lance) in the San Juan Channel Sand Wave
(Friday Harbor Laboratories, 2013-12)Ammodytes hexapterus or Pacific sand lance (PSL) are forage fish that spend most of their time buried in benthic substrate (Robards 1999). PSL exhibit a peculiar behavior of actively swimming into sandy substrates as a ... -
Characterizing Pacific sand lance habitat in the San Juan channel sand wave field
(Friday Harbor Labratories, 2012-12)In the pelagic zone Ammodytes hexapterus or the Pacific Sand lance (PSL) act as an important link in the food web feeding on planktons and being preyed on by a wide variety of higher trophic level predators (Martin et al., ... -
Characterizing seasonal dormancy and the physiological threshold for survival in Pacific sand lance (Ammodytes personatus)
(2023)Pacific sand lance (Ammodytes personatus) go dormant through the winter. As foraging decreases, sand lance experience a decline in body condition. Natural mortality may occur due to starvation if body condition decreases ... -
Chemical Signaling In An Inducible Offense
(Friday Harbor Laboratories, 2013-08)Inducible phenotypic plasticity is the ability of an organism’s genotype to express different observable traits or phenotypes, such as morphology, over and individual’s lifespan. The snails Lacuna vincta and L. variegata ... -
Clark 1 Land-based versus water based observation of Orcinus orca near San Juan Island, Washington
(Friday Harbor Labs, 2011-09)Southern resident killer whales seasonally inhabit the Salish Sea waters of British Columbia and Washington and are unique in their feeding behavior. This endangered subpopulation is also a valued resource that has led ... -
Claw morphology and influence on feeding electivity of four Pacific Northwest crab species
(Friday Harbor Laboratories, 2014-12)Crabs use their claws for a number of uses including handling and processing of prey items. However claws are not uniform across species, they show a number of variations including those in their denticle patterns. To ... -
Coccolith Conundrum: How shape affects sinking and light acquisition
(Friday Harbor Laboratories, 2012-08)I use three simple models to assess the degree to which thickness of the upper element of a coccolith and the height of the connecting stalk influence a coccolithophore’s sinking rate, and ability to acquire light. One ... -
Collagen type IV in the Ctenophore Pleurobrachia bachei
(2012)The evolution of multicellular animals required the development of epithelial tissues that function in controlling the transport of molecules from one environment to another. Collagen proteins are crucial to the formation ... -

The Collagens of the Ctenophore Pleurobrachia bachei
(Friday Harbor Laboratories, 2012-10)The evolution of multicellular animals required the development of epithelial tissues that function in controlling the transport of molecules from one environment to another. Collagen proteins are crucial to the formation ... -
COLONISATION BY THE WOOD-BORING BIVALVE XYLOPHAGA WASHINGTONA
(Friday Harbor Laboratories, 2014-08)Wood falls represent a rare and ephemeral, yet important source of food in the deep-sea. Wood-boring bivalves of the family Xylophagainae have high reproduction and growth rates, allowing them to rapidly colonise and exploit ... -

A comparative analysis of the novel terrestrial locomotion of the tidepool sculpin, Oligocottus maculosus
(Friday Harbor Laboratories, 2015-09)Tidepool sculpins (Oligocottus maculosus) are intertidal fish that use a novel mode of terrestrial locomotion to traverse their semi-terrestrial environment. Our goals were to describe the kinematics of the terrestrial ...
