Fasta file of All Wnt genes
2017-01-01
Sally Leys, Pamela Windsor-Reid
ABSTRACT Background: The Wnt signaling pathway is uniquely metazoan and used in many processes during development, including the formation of polarity and body axes. In sponges, one of the earliest diverging animal groups, Wnt pathway genes have diverse expression patterns in different groups...

Data from: Behaviors of sessile benthic animals in the abyssal northeast Pacific Ocean
2020-01-07
Kahn, Amanda S., Pennelly, Clark W., McGill, Paul R., Leys, Sally P.
Time-lapse photography provides a view of the seafloor at timescales that make it possible to recognize behaviors and activity of often slow-moving abyssal fauna. Most behavioral studies have focused on mobile animals; sessile benthic fauna have largely been overlooked. We combed through 30 years...

The LAB60 simulation is a coupled ocean sea-ice model (NEMO) that uses grid refinement to achieve high resolution (1/60 of a degree) within the Labrador Sea. This simulation starts in 2002 and will cover a period of over 10 years. This video shows the relative vorticity of the upper 55m ocean...

Molecular and functional bases of coordination in early branching metazoans – insights from physiology and investigations of potassium channels in the Porifera
DownloadFall 2010
Tompkins MacDonald, Gabrielle Jean
Sponges are filter feeders that lack nerves and muscle but are nonetheless able to respond to changes in the ambient environment to control their feeding current. Cellular sponges undergo coordinated contractions that effectively expel debris. Syncytial sponges propagate action potentials through...

Suspension feeders are an important component of carbon exchange between the water column and the seafloor, a process called pelagic-benthic coupling. Sponges (Phylum Porifera) are filter feeders that consume especially small particles. They eat bacteria, which are inaccessible to most other...

Benthic marine habitats in Canada have been well-sampled since the annual groundfish survey commenced in 1970. However, trawl surveys cover only non-rocky sediments and many species collected are not identified to lower taxa, leaving large gaps in our understanding of benthic diversity. Sponges...

Extreme High Greenland Blocking Index Leads to the Reversal of Davis and Nares Strait Net Transport Toward the Arctic Ocean
Download2021-01-01
Myers, Paul G., de al Guardia, Laura Castro, Fu, Chuanshuai, Gillard, Laura C., Grivault, Nathan, Hu, Xianmin, Lee, Craig M., Moore, G. W. K., Pennelly, Clark, Ribergaard, Mads Hvid, Romanski, Joy
Baffin Bay exports Arctic Water to the North Atlantic while receiving northward flowing Atlantic Water. Warm Atlantic Water has impacted the retreat of tidewater glaciers draining the Greenland Ice Sheet. Periods of enhanced Atlantic Water transport into Baffin Bay have been observed, but the...

Gillard, Laura C., Hu, Xianmin, Myers, Paul G., Bamber, Jonathan L.
The Greenland ice sheet (GrIS) stores the largest amount of freshwater in the Northern Hemisphere and has been recently losing mass at an increasing rate. An eddy-permitting ocean general circulation model is forced with realistic estimates of freshwater flux from the GrIS. Two approaches are...

Using Vertically Integrated Ocean Fields to Characterize Greenland Icebergs’ Distribution and Lifetime
Download2018-01-01
Marson, Juliana M., Myers, Paul G., Hu, Xianmin, Le Sommer, Julien
Icebergs represent approximately half of Greenland’s yearly mass loss, having important implications for biological productivity, freshwater fluxes in the ocean, and navigation. This study applies an iceberg model that uses integrated ocean fields (from surface to iceberg keel) to simulate the...
