Bacteria Abundance in Response to Increasingly Acidic Conditions
(2012)The objective of this mesocosm experiment is to determine differences in bacteria abundance in normal (600μatm), medium (1000μatm), and high (1300μatm) CO2 concentrations. Mesocosms serve as an intermediate for lab and ... -
Bacteria Abundance in Response to Increasingly Acidic Conditions
(Friday Harbor Laboratories, 2012-06)Global warming is a worldwide phenomenon that is the result of anthropogenic input of carbon dioxide into the atmosphere. Although the increase in carbon dioxide levels now is 100 times faster than at the end of the last ... -
Beach morphology and grain-size changes over short timescales at the Elwha River Delta, WA
(Friday Harbor Laboratories, 2013-06)The Elwha River dam removal project is the largest such project carried out in the U.S., and offers a unique opportunity to study the effects of a sudden sediment flux from the river to the coastal environment. A huge ... -
Beach Wrack Nutrient Leaching and Community Composition on Gravel Beaches
(Friday Harbor Laboratories, 2014-12)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 ... -
Behavior and distribution of Phoca vitulina and Eumatopias jubatus in the San Juan Archipelago
(Friday Harbor Labs, 2011-09)Changes in tidal patterns affect the prey composition of the two most common pinnipeds in the San Juan Channel, the harbor seal (Phoca vitulina) and Steller sea lion (Eumatopias jubatus).Tidal influences are therefore ... -
Behavioral and neural activity during magnetic stimulation of Tritonia tetraquetra imply conditional magnetotactic response
(Friday Harbor Laboratories, 2014-08-30)A variety of species are known to sense and respond to the geomagnetic field for navigation. The sea slug Tritonia tetraquetra (a.k.a. Tritonia diomedea) has been shown to respond to the magnetic field through both ... -

(Friday Harbor Laboratories, 2014-08)A variety of species are known to sense and respond to the geomagnetic field for navigation. The sea slug Tritonia tetraquetra (a.k.a. Tritonia diomedea) has been shown to respond to the magnetic field through both ... -
Bent out of shape: Bioinspired vertebral column morphology and mechanics
(Friday Harbor Laboratories, 2013-12)The vertebral column plays an essential role in body stiffness and swimming. Greater body stiffness results in greater mechanical outputs from the body on the environment. Previous work in bioinspired systems has shown ... -
Benthic community assemblages in the San Juan Islands: Do abiotic factors influence community composition at small spatial scales?
(2011)There are many factors contributing to the composition of biological communities in coastal marine habitats worldwide. Operating over large regional spatial scales, abiotic variables such as temperature and oceanic current ... -
Benthic Macrofauna Abundance Along a Transect from False Bay, San Juan Island
(Friday Harbor Laboratories, 2014-08)Benthic macrofauna are a diverse group of organisms found in both deep-sea and shallow-water systems. Understanding the influence of biotic and abiotic factors in shallow-water systems can translate to further understanding ... -

Beroe abyssicola Patterns of Predation: A Behavioral Analysis
(2021)Ctenophores play an important role in many marine ecosystems worldwide and affect multiple trophic levels. They consume large amounts of plankton while, in turn, are also consumed by fish. Beroe abyssicola is a carnivorous ... -
Bigger, Stronger but Not Faster: ontogenetic change in the jaw biomechanics of the great sculpin, Myoxocephalus polyacanthocephalus
(Friday Harbor Laboratories, 2014-08-30)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 ... -

Bioenergetic Effects of Cutting Mussel Byssus Threads, Mytilus trossulus
(Friday Harbor Laboratories, 2014-06-30)Mussels are filter feeders living and thriving in the harsh conditions of the intertidal environment. Many factors attribute to their success including aggregating in groups, hard shells, but more specifically their ... -

Biomass Effects on Carbonate Chemistry in both a Flow-through and Static Experimental Laboratory Set-up
(Friday Harbor Labs, 2011-07)There are many things to consider when setting up experimental laboratories, especially in the context of ocean acidification. We studied the impact of biomass load and flow-through rate on the carbonate chemistry of ... -

The biomechanics and burrowing methods of Ammodytes hexapterus
(Friday Harbor Labs, 2011-05)The Pacific sand lance, Ammodytes hexapterus, was tested for burrowing speed in a tank filled with sediment topped with seawater. Results show that in fine sand (0.520mm in diameter) young of the year sand lance burrow ... -
Bite and Suction Forces of the Adductor Muscle in Four Sculpin Species
(Friday Harbor Laboratories, 2014-06)To prevent constant competition across species, different species may develop different morphologies to increase their ability to attain a certain food source within a niche. By dissecting the adductor muscle and taking ...
