SSHRC IDG Awarded 2018. This study aims to answer the question: ‘How has the illicit introduction of opioid fentanyl and its ‘analogues’ such as carfentanyl, altered life in Alberta’s prisons? In Canada's opioid crisis, prisons end up housing a disproportionate number of the marginalized and...

Abstract: Sponges (Porifera) are abundant in most marine and freshwater ecosystems and as suspension feeders they play a crucial role in filtering the water column. Their active pumping enables them to filter up to 900 times their body volume of water per hour, recycling nutrients and coupling a...

SSHRC Awarded IG 2019: Our four-year study explores how disabled men with diverse impairments and subject positions experience and enact masculinity through fashion. We use fashion as a research context and an arts-based method to generate new understandings of masculinity and disability. Our...

Cryo-electron microscopy of SERCA interacting with oligomeric phospholamban and oligomeric sarcolipin

In 2007, heart disease was the second leading cause of death in Canadians. In heart muscle cells, calcium (Ca2+) is released from the sarcoplasmic reticulum (SR) during contraction and must be replenished for relaxation to occur. Three proteins restore Ca2+ to the SR following contraction: the...

Data associated with Aragones and Leys - "The sponge pump as a morphological character in the fossil record"
Download2021-08-13
The timing of early animal evolution remains one of the biggest conundrums in biology. Molecular data suggest Porifera diverged from the metazoan lineage some 800 Ma to 650 Ma, which contrasts with the earliest widely accepted fossils of sponges at 535 Ma. However, the lack of criteria by which...

The largest known glass sponge reefs in Canada are within the Hecate Strait and Queen Charlotte Sound Glass Sponge Reefs Marine Protected Area (HSQCS-MPA). However, human activities outside the core MPA boundaries, such as trawling, can create plumes of suspended sediments capable of travelling...

Bottom-contact trawling generates large, moving clouds of suspended sediments that can alter the behaviour of organisms adjacent to trawl paths. While increased suspended sediment concentrations (SSCs) are known to cause glass sponges to arrest filtration in lab studies, the response of sponges...

Data associated with Matveev et al: Sense Induced Flow - Active use of ambient flow by a deep-sea glass sponge

Matveev, E, Leys SP, Yahel G, Kahn AS, Aragones P, Ludeman D, Eerkes-Medrano D
How flow moves through porous structures like sponges is a fluid dynamic problem that has challenged physical and biological scientists. Sponges possess biological pump cells that are known to drive water flow, and yet their porous bodies have often been proposed to take advantage of ambient...
