Sponges are suspension feeders that use flagellated collar-cells (choanocytes) to actively filter a volume of water equivalent to many times their body volume each hour. Flow through sponges is thought to be enhanced by ambient current, which induces a pressure gradient across the sponge wall,...

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...

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...

Bacterial viruses (phages) are ubiquitous in the environment and are believed to target every bacterial species. Phages utilize receptor binding proteins (RBPs) to bind specifically to their host cell surface. The Campylobacter jejuni phage NCTC 12673 RBP and its capsular polysaccharide (CPS)...

Source code for an R package that can be used to simulate and apply various search strategy models to movement data. This is the code used in the manuscript entitled: Differentiating the Lévy walk from a composite correlated random walk. See https://github.com/MarieAugerMethe/CCRWvsLW for any...

This the data associated with the manuscript entitled: Differentiating the Lévy walk from a composite correlated random walk. It is the step lengths and turning angles of two bears collared in the Hudson Bay. The data is the step length and turning angle measured at regular time intervals (every...

This is a dataset of measurements of the canal system of the glass sponge Farrea occa, together with an analysis of the head loss (pressure drop) between incurrent and excurrent sides of the sponge

Ecological systems are complex. All too often, complex models are fit to ecological data without consideration of whether parameters are estimable. I present a recent example for a parasite transmission model tracking the diffusion of sea lice from salmon farms in coastal British Columbia, fit...

Surfaces contaminated with Staphylococcus aureus can play an important role in its transmission throughout communities and hospitals. Previous research on S. aureus surface survivability has generally used high density inocula (>105 CFU mL-1), which may lead to cryptic growth of the cells, as...
