FA signatures of the diatom Skeletonema cf. marinoi: just how natural is culturing anyway?
(Friday Harbor Laboratories, 2012-06)Spatial subsidies including particulate organic matter (POM) play an important role in near-shore food web ecology. Fatty acid (FA) analysis has proven an effective tool for constructing these food webs, although the FA ... -

Factors affecting San Juan Channel and Puget Sound water properties during fall 2014
(Friday Harbor Laboratories, 2014-12)Estuarine density gradient circulation patterns depend on seasonal and tidal temperature and salinity shifts. Changes to these properties affect the residence time and flushing of each fjord-like basin. Abnormal temperature ... -
Factors influencing phytoplankton and dissolved oxygen in San Juan Channel: a spatial and temporal assessment
(Friday Harbor Labs, 2011-12)The purpose of study was to investigate how physical and biological factors influence phytoplankton and dissolved oxygen spatially and temporally in San Juan Channel over fall and the annual cycle of 2011. Specific objectives ... -

Feeding behavior of Tigriopus californicus fed urchin feces vs fresh algae
(Friday Harbor Laboratories, 2014-06-30)Primary productivity does not occur in deeper waters due to limiting light availability, and thus deep subtidal organisms receive energy in the form of detritus. Urchins in the San Juan Archipelago catch and consume large ... -

Feeding ecology of forage fishes in the San Juan Archipelago: Diet composition and variation in Ammodytes hexapterus, Hyperprosopon ellipticum, and Clupea pallasii
(Friday Harbor Laboratories, 2014-12)Forage fish play an important role in wasp-waist ecosystems like that of the San Juan Archipelago. These small fish, including the Pacific sand lance, silver surf perch, and Pacific herring, regulate the flow of energy ... -
Feeding electivity of Pugettia gracilis, the graceful kelp crab (Decapoda: Epialtidae), and its potential importance to nearshore kelp forests
(Friday Harbor Laboratories, 2013-06)Kelp forests are an integral part of complex marine food webs, and it is important to be aware of the roles of the varied consumers in kelp forests to understand the complexityofthefoodwebsinsuchanecosystem. Thetradition ... -
Feeding Mechanics and Functional Morphology in the Jaws of Sculpins
(Friday Harbor Laboratories, 2015-09)Species with overlapping geographic ranges, similar morphology, and ecological roles often vie for the same resources and therefore face competitive exclusion. This competition can be reduced if species vary in skeletal ... -
Feeding Preferences and Potential Competition between Ariolimax columbianus and Arion rufus
(Friday Harbor Laboratories, 2014-08-30)Within the last 100 years, the arrival in the Pacific Northwest of the invasive European slug Arion rufus has introduced a potential competitor for the iconic banana slug Ariolimax columbianus, the second largest terrestrial ... -

Feeding Preferences of Red Urchins, Strongylocentrotus franciscanus, to Drift Kelps
(Friday Harbor Labs, 2011-09)Kelps and major contributors to primary production in temperate marine ecosystems. Kelps also make up a high amount of biomass and provide structure and habitat to many organisms. However, little kelp biomass is directly ... -
Feeding responses of the mysid Archaeomysis grebnitzkii to fresh and aged blended Nereocystis luetkeana
(Friday Harbor Laboratories, 2012-06)The mysid Archaeomysis grebnitzkii is a small detrivorous crustacean that is prey to many low level consumers. In vitro, we fed A. grebnitzkii fresh and aged blended Nereocystis luetkeana as well as a blend of phytoplankton ... -

Feeding Strategies of Great Blue Herons (Ardea herodias fannini) in False Bay, San Juan Island
(Friday Harbor Laboratories, 2014-08)Abundance and foraging habits in Great Blue Herons (Ardea herodias fannini) are correlated with habitat type, tide phase and height, and group size in False Bay in the San Juan Islands, Washington. We completed field surveys ... -

Feeding the Masses: Colonial Transport in the Marine Bryozoan Membranipora membranacea
(Friday Harbor Laboratories, 2014-08-30)The transport system of cheilostome bryozoans is unusual among long-distance transport systems. In these colonial animals, a network of strands (the funicular system) carries nutrients to non-feeding individuals and to the ... -

A field based assessment of predation impacts on planktonic egg capsules across depth and flow gradients
(Friday Harbor Laboratories, 2014-10)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 ...
