Radular Morphology among Chiton in Family Mopillidae
(Friday Harbor Laboratories, 2014-07)The Mollusca radula is an intricate organ composed of several rows of teeth running along a chitinous ribbon. Several studies have looked at radula of gastropods but fewer have looked at the radula of Polyplacophora. An ... -

Recovery rates of starved and fed Nucella ostrina after heat-induced stress
(Friday Harbor Laboratories, 2013-06)How much effect does nutritional state have on the recovery time of Nucella ostrina from low tide stresses? We predicted that fed N. ostrina would recover faster from low tide stress than starved ones. Fed and starved ... -
Reduced oxygen consumption after critical oxygen level does not immediately impair optimal swimming performance in the Pile Perch, Rhacochilus vacca
(2019)Hypoxia is a stressor that occurs naturally in the environment. Hypoxic episodes are increasing globally due to anthropogenic nutrient loading and further exacerbated by global warming. This study examines the effect of ... -
Regeneration and Regrowth of Mycale sp., Halochondira panicea and Phakellia sp. Sponges in the Pacific Northwest
(Friday Harbor Laboratories, 2012-07)Sponges (phylum Porifera) fall short of being considered true animals, Eumetazoas, because of their unique tissue organization. This organization is questionability multicellular because of their cell-to-cell nutrient ... -
Regeneration in worm larvae, Family Spionidae
(2019)Metazoan lineages exhibit a wide range of regenerative capabilities in their adult forms, however, less is known about larval regeneration. Our study evaluated whether larvae of Spionid worms were capable of regeneration. ... -
Remote sensing illustrates patterns of change and permanence in eelgrass meadows, False Bay Washington
(2021)Seagrasses are an important global resource which serve as ecosystem engineers, providing a wide range of ecosystem functions and services. Unfortunately, many seagrasses such as eelgrass (Zostera marina) are declining in ... -
Response of Haptera Growth to Different Frequencies of Light in Deep Water Agarum fimbriatum and Shallow Water Alaria marginata
(Friday Harbor Laboratories, 2014-06-30)Light plays an important role in kelp ecology as an energy source and as an important kelp growth regulator. It induces a negative phototropic response in kelp haptera. Because longer wavelengths of light are available at ... -

Responses of the mysid Archaeomysis grebnitzkii to phytoplankton and kelp diets
(Friday Harbor Laboratories, 2012-06)The mysid Archaeomysis grebnitzkii is an important detritovore and prey in many food webs. In this experiment A. grebnitzkii was feed phytoplankton, blended fresh kelp, and blended aged kelp for 15 days while growth and ... -

Resuspension and Advection as Sediment Transport Processes in the Elwha Delta Nearshore Environment
(Friday Harbor Labs, 2013)The largest dam removal project in U.S. history began on the Elwha River in 2011. A large quantity of sediment was expected to enter the marine environment, but where this sediment would end up and how it would get there ... -
Riders on a Shell: The Effect of Algal Epibionts on Eagle Cove Limpets
(2023)Limpets and algal epibionts develop mutually beneficial associations. This study examines the benefits of green algal epibionts on the limpet Lottia pelta at Eagle Cove. Density of algal cover was compared between ... -
Rise with the Incandescent Sun: A look at Diel Cycling and growth of Dendraster excentricus in Response to Incandescent Light
(2019)The pluteus larvae of the sand dollar Dendraster excentricus and their diel vertical distribution have been well studied in the field and in lab. However, there has not been much focus on how the larvae and their vertical ... -
The role of flow in determining zooplankton populations inside and outside kelp beds near the San Juan Islands.
(Friday Harbor Laboratories, 2014-05-30)This study explored the relationship that flow in Nereocystis luetkeana beds has to zooplankton communities in the San Juan Islands. The hypothesis was that current flow rates would decrease further inside a kelp bed and ... -

A rough estimate of ghost shrimp (Neotrypaea californiensis) population characteristics in False Bay, San Juan Island, Washington
(2021)Neotrypaea californiensis are a burrowing decapod species that acts as an important ecosystem engineer and bioturbator in intertidal sandflats. Using a novel sampling method, the abundance of N. californiensis individuals ... -
Running Head. — Feeding Ecology of Ammodytes hexapterus
(Friday Harbor Labratories, 2012-12)Forage fish such as herring, surf perch and Pacific sand lance are a crucial link between lower and upper elements in the food chain, transferring dense energy and vitamin content from primary producers (phytoplankton) to ... -
Saccharina compla(nada?) Species Determining the validity of S. complanata as a distinct species
(2023)The kelp species Saccharina complanata (order Laminariales, family Laminariaceae) originally described as Saccharina latissima f. complanata, is a poorly understood species, often overlooked in studies involving other ...
