Reiswig, Henry M, Leys, Sally P, Diluvio, MS
These notebooks were scanned by Maria Diluvio from Henry Reiswig's collection. Henry kept meticulous notes for all of his life (1936-2020). Henry's work was on sponges (Phylum Porifera).

Maldonado, M, Bayer, K, Lopez-Acosta, M
SUMMARY Several inorganic compounds of nitrogen (N) and phosphorus (P) are key to ocean ecology because, among other effects, they sustain primary production. After discovering in the 1980s that sponges can be both source and sink of such nutrients, much has been learned, including that fluxes...

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...

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...

Hill, April L, Camilli, Sara, Dwaah, Henry, Kornegay, Benjamin, Lay, Christine A, Hill, Malcolm S
In many freshwater habitats, green algae form intracellular symbioses with a variety of heterotrophic host taxa including several species of freshwater sponge. These sponges perform important ecological roles in their habitats, and the poriferan:green algae partnerships offers unique...

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...

Supplementary Files for: Sponge behaviour and the chemical basis of responses: a post-genomic view
Download2019-05-25
Sponges perceive and respond to a range of stimuli. How they do this is still difficult to pin down despite now having transcriptomes and genomes of an array of species. Here we evaluate the current understanding of sponge behaviour and present new observations on sponge activity in situ. We also...

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...
