Zooplankton are secondary producers that play a major role in carbon sequestration, the
microbial loop, and energy transfer across trophic levels. Zooplankton are abundant in the
Salish Sea, a productive inland sea with ...
Prevalent upwelling in summer months in the Northwest United States can bring anomalously acidified waters to Puget Sound. This, combined with the effects of increasing summer peak water temperatures, poses a joint threat ...

Beaches world-‐wide have low primary production due to a stressful environment and action of strong hydrodynamic forces. For this reason, input from marine wrack as well as terrestrial debris is an important source of ...
The meiofaunal assemblage on the invasive brown alga, Sargassum muticum, was compared to that on three native algal species. I predicted that differences in the meiofaunal diversity, abundance, and community composition ...

The development of larval fishes is a chronically understudied, critically important field, which offers broad insight into a defining period in the life history of fishes. Examinations of development shed light on the ...
With more anthropogenic CO2 equilibrating with the oceans and decreasing the concentration of carbonate ions, ocean acidification is a current concern for all marine organisms, especially those that build calcium carbonate ...
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 ...

Suction feeding is the most common vertebrate feeding mode. Fishes suction feed by rapidly expanding the buccal cavity, creating a subambient pressure inside the mouth that causes water (and, ideally, a prey item) to rush ...
[author supplied abstract] This study investigates where carbon in marine surface sediments originates from, as well as how seafloor peaks and valleys influence the distribution of carbon in Barkley Sound, Vancouver Island, ...
In this study, we investigated how intertidal algal canopies affect susceptibility of limpets to predation and also how the temperature experienced by limpets at low tide affects limpet susceptibility to predation at high ...
Wnt signaling is known to be critical for proper embryonic development in most animals studied to date15. But key evolutionary questions on the origin and evolution of this pathway in the metazoan common ancestor are still ...
Sea stars are common invertebrates that inhabit all oceans. These organisms belong to the phylum Echinodermata, which include sea cucumbers, sand dollars and sea urchins. The sea star Pisaster ocharaceus is native to the ...
The sensory organs of larvae of the bryozoan Bugula c.f. californica are very important during the short transition from the swimming phase to the brief settlement phase. These sensory organs detect environmental cues that ...
A recent outbreak of sea star wasting syndrome (SSWS) along the U.S. West coast has decimated populations of many intertidal and subtidal sea star species. If populations are unable to recover quickly, SSWS is likely to ...
One of the arguments for the persistence of planktonic larval stages in the life cycles of benthic marine invertebrates is that pelagic larvae experience a release from predation when they move off the benthos and into the ...
The larval swimming patterns prior to settlement play an important role in geographic dispersal and genetic connection for sessile marine organisms. This study examined how swimming patterns and size change with age for ...
The relative rates of mortality in benthic and pelagic environments have been proposed as a major factor structuring the evolution of complex benthic invertebrate life histories. Field methods, such as tethering, have ...
Planktonic larval development, common in many benthic marine invertebrates, is associated with both costs and benefits relative to benthic larval development. Costs of being in the plankton include increased susceptibility ...
The benefits of spines in zoea and other crustaceans have been documented in numerous studies as a form of anti-‐predatory behavior. This study examined the potential costs of having spines using three different methods. ...
The behavior of sea star brachiolaria larvae is poorly understood and the role of their elongated posterior processes in swimming is unknown. We attempt to characterize swimming speed and behavior in the late stage ...
