Magnetotaxis and orientation of chitons Mopalia muscosa
(Friday Harbor Laboratories, 2012-07)Previous studies on magnetotaxis behavior have found a diverse range of taxa, such as reptiles, birds, and even bacteria, that use magnetite to gather information about their geographic position based on gradients in the ... -
Marine Mammals in the San Juan Channel
(Friday Harbor Labs, 2011-12)Since 2005, one site has been studied in the San Juan Channel, located just off San Juan Island, Washington in the United States. This research has been done by the Pelagic Ecosystem Function Apprenticeship at the Friday ... -
Marine Mammals in the San Juan Channel, Autumn 2011
(2011)Since 2005, one site has been studied in the San Juan Channel, located just off San Juan Island, Washington in the United States. This research has been done by the Pelagic Ecosystem Function Apprenticeship at the Friday ... -
Marine Sedimentary Processes Research Apprenticeship
(Friday Harbor Laboratories, 2012-06)Suspended-sediment concentrations (SSCs) in the Elwha River and nearshore environment off the river mouth were observed in order to determine the effects of the Elwha dam removal project on sediment supply to the river and ... -
The mechanical properties of the body wall might enable elongation in Leptosynapta clarki
(Friday Harbor Laboratories, 2013-12)Organisms have to behave within the range of mechanical properties of their body. Leptosynapta clarki, collected from False Bay, San Juan Island, WA, exhibited undocumented elongation behavior that might be associated ... -
Meiofaunal Diversity on Invasive Sargassum muticum Versus Native Seaweeds
(Friday Harbor Laboratories, 2014-12)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 ... -
Metamorphosis genes are expressed early during Molgula occulta and Molgula oculata development
(Friday Harbor Labs, 2011-09)Ascidians and vertebrates share very similar chordate characteristics during their developmental stages. Since both lineages have highly conserved genomes we are able to make evolutionary comparisons between the two ... -

Metridium farcimen show little to no preference for prey particle size
(Friday Harbor Laboratories, 2014-06)The overabundance of one species in a particular area is typically bolstered by a biotic or abiotic factor that allows them to outcompete other species for space and resources. The undersides of the docks in the town of ... -

Migration and feeding in intertidal whelks, N. ostrina and N. lamellosa
(2012)Our study seeks to gain more information on the migration and feeding patterns of two common intertidal carnivorous snails, Nucella lamellosa and Nucella ostrina. These whelks are native to the western coast of the United ... -

Modeling the pelvic suctorial region of Eumicrotremus orbis
(Friday Harbor Labs, 2011-05)The rocky intertidal zone is a stressful environment inhabited by many organisms with specialized adaptations. One adaptation seen in several families of fish is to use a pelvic suctorial organ to attach to the substrate. ... -
Molecular and Physical Relationships among Individuals in a Phoronis vancouverensis Clump
(Friday Harbor Labs, 2011-09)Within the bilateria, in the group Lophotrochozoa, there are at least two phyla that have evolved coloniality: Bryozoa and Entoprocta. Most of the phyla are solitary, and reproduce only sexually (Davidson et al. 2004). ... -
The Molecular Evolution of Hedgehog in Stolidobranchia Ascidians
(Friday Harbor Labs, 2011-09)Ascidians are highly studied in evolution and development because they have a tiny chordate tadpole larva. As a sister clade to vertebrates, ascidian research has lead to greater understanding of the molecular roles of ... -
Molecular Searching for Gill Slits in Echinoderms: Hox1 expression in Strongylocentrotus purpuratus
(Friday Harbor Laboratories, 2013-06)The formation of gill slits is a homologous trait in most deuterostomes (including hemichordates, tunicates, lancelets, and vertebrates), however is not present in the Phylum Echinodermata. Thus, there may be a difference ... -
Molgulid ascidians share a unique gene complex
(Friday Harbor Labs, 2011-09)Typical chordate features found in ascidian tadpole larvae have been evolutionarily lost several times independently within the Molgulidae family. While tailed molgulids retain a tail with muscle cells, a notochord, and ... -
Morphological Characters and Molecular Analysis of Some Endolithic Green Algae
(Friday Harbor Laboratories, 2012-08)Morphological and molecular (ITS and TufA nuclear DNA) analysis was carried out on some endolithic green algal strains to examine their relationship and boring activity. Using the BLAST, the closest relative to most of ...
