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 goal of this guide is to derive a better understanding of the biodiversity of sponges across the eastern Canadian Arctic. Specimens were collected during research cruises aboard the Canadian Coast Guard Ship (CCGS) Amundsen in October 2015, July 2016 and July 2017. Collection sites were...

A deep sea (1148m) Agassiz trawl is returning to the deck of the CCGS Amundsen during a cruise in the Arctic. This trawl was targeted at sampling benthic epifauna near reported black coral habitat. My research goals are to describe the diversity of sponges in the Eastern Canadian Arctic and...

Sponges link the microbial loop with benthic communities by feeding on bacteria. Glass sponge reefs on the continental shelf of western Canada have extremely high grazing rates, consuming seven times more particulate carbon than can be supplied by vertical flux alone. Unlike many sponges, the...

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 including...
