Abundance and Distribution of Harbor Porpoises and Other Cetaceans in the San Juan Channel: Tides and Bathymetry
(Friday Harbor Laboratories, 2014-12)The Salish Sea, an area of complex oceanography and bathymetry, supports a number of apex cetacean species. In the last decade, anomalous sightings of cetaceans have become more frequent and shifts in species abundance ... -
The Abundance, Distribution, and Interaction of Rhinoceros Auklets, Cerorhinca monocerata and Gulls, Laridae In San Juan Channel, WA
(Friday Harbor Labs, 2011-09)Rhinoceros Auklets and gulls use the San Juan Channel as foraging grounds. They have shown complementary roles in feeding activity; a kleptoparasitism interaction. Few studies have characterized the Rhinoceros Auklets ... -
The Affect of Ontogeny on Structure and Function of Preopercular Spines in Myoxocephalus polyacanthocephalus
(Friday Harbor Laboratories, 2014-07)I investigated the affect of ontogeny on the structure and function of pre-opercular spines. By measuring how these spines matched up against the standard length of the animal. Spines were surgically removed from ... -
The Affect of Ontogeny on Structure and Function of Preopercular Spines in Myoxocephalus polyacanthocephalus
(Friday Harbor Laboratories, 2014-07)I investigated the affect of ontogeny on the structure and function of pre-°©‐opercular spines. By measuring how these spines matched up against the standard length of the animal. Spines were surgically removed from ... -
Analysis of fast-start movements using accelerometry and video tracking in the Great Sculpin (Myoxocephalus polyacanthocephalus)
(Friday Harbor Labs, 2011-09)While the use of accelerometers in the aquatic environment becomes an increasingly used tool in remotely observing animals; however, the data obtained from deploying accelerometers still needs better understanding. ... -

An Analysis of Salinity Stratification in San Juan Channel
(Friday Harbor Laboratories, 2014-12)The Salish Sea in an estuarine circulation system comprising of the Fraser River in Canada and the Pacific Ocean. Stratification in the San Juan Channel is variable by two very distinctly different means in the north and ... -
An Analysis of San Juan River Otter (Lontra canadensis) Diets
(Friday Harbor Laboratories, 2014-06-30)This study analyzes the diets of Lontra canadensis populations on San Juan Island, Washington. It tests the hypothesis that the majority of river otter diets, in the populations studied, is composed of fish and crustacean ... -
An Analysis of San Juan River Otter (Lontra canadensis) Diets
(Friday Harbor Laboratories, 2014-06)This study analyzes the diets of Lontra canadensis populations on San Juan Island, Washington. It tests the hypothesis that the majority of river otter diets, in the populations studied, is composed of fish and crustacean ... -
Analyzing Vessel Interactions Surrounding Southern Resident Killer Whales (Orcinus orca)-‐ Summer 2011
(2011)As global biodiversity continues to decline greater attention is being paid on ways law can be a mechanism to advance conservator efforts. Currently, southern resident killer whales are listed ... -
Analyzing Vessel Interactions Surrounding Southern Resident Killer Whales (Orcinus orca)
(Friday Harbor Labs, 2011-12)As global biodiversity continues to decline greater attention is being paid on ways law can be a mechanism to advance conservator efforts. Currently, southern resident killer whales are listed as ‘endangered’ under the ... -
Annual and interannual patterns of physical oceanographic properties in the San Juan Channel: effects of external drivers
(Friday Harbor Laboratories, 2013-12)The San Juan Channel (SJC) lies within the Salish Sea between Washington state, USA and British Columbia, Canada. As an estuary, the physical oceanographic conditions of the SJC change constantly over small and large periods ... -
Apoptosis as Potential Cause for Notochord Cell Loss in Molgula occulta
(Friday Harbor Labs, 2011-09)The evolution of the chordate body plan is still unresolved. Notochord evolution can be studied with two tunicates—the tailed M. oculata and the tailless M. occulta. The tailed M. oculata has 40 notochord cells that are ... -
Assessing muscle function in the hagfish feeding apparatus of Eptatretus stoutii
(Friday Harbor Laboratories, 2015-09)Hagfish are marine chordates that, despite lacking jaws, are able to feed on large, tough carcasses with the protraction and forceful retraction of toothplates. Using muscle stimulation experiments, we studied the function ... -
Assessing the State of Pteropod Shells and Ocean Acidification in Washington Marine Waters
(Friday Harbor Laboratories, 2014-12)The relationship between pteropod shell dissolution and waters undersaturated with aragonite has been well documented (Bednarsek et al 2012). Low aragonite saturation levels decrease the availability of carbonate ions ... -
Assimilation efficiency of Idotea wosnesenskii on different algal diets
(Friday Harbor Laboratories, 2013-06)Drift algae are an important resource in marine food webs and undergo a vital change in chemical composition during the degrading (or aging) process. I investigated the effects of aging algae and different species of algae ... -
Attachment forces and the role of suction in the sea anemone Metridium farcimen
(Friday Harbor Laboratories, 2014-06)This paper looks at the forces involved in the attachment of M. farcimen to substrate. Many sessile and transitory, aquatic animals rely on the secretion of an adhesive glue for attachment to substrate, like most sea ...
