Vision is an important sense for fish and, as various properties of the water column affect how well different light wavelengths are transmitted, fishes’ visual sensitivity spectra reflect the varying ambient light conditions across habitats. Syngnathids (pipefishes & seahorses) inhabit various salt- and freshwater habitats-many affected by geological, anthropogenic and seasonal changes, challenging these visual predators. Her...
Addressing urgent conservation issues, such as the drastic declines of North American migratory birds, requires creative, evidence‐based, efficient, and collaborative approaches. The abundance of over 50% of monitored North American shorebird populations has declined by over 50% since 1980. To address these declines, we developed a partnership of scientists and practitioners called the Shorebird Science and Conservation Collec...
Ocean acidification (OA) generally receives far less consideration than other climate stressors and related hazards, such as global warming and extreme weather events. Canada is uniquely vulnerable to OA given its extensive coastal oceans, the oceanographic processes in its three basins, accelerated warming and sea-ice melt, and extensive coastal communities and maritime economic sectors. Canada’s coastline is also home to ext...
Aerosol Delivery of Polyelectrolyte Surfactant—Antimicrobial Nanoparticles to the LungsNARA Subscribed
Background Lung infections affect over 80% of adults with cystic fibrosis, with Pseudomonas aeruginosa being a leading pathogen. Although antibiotics are frequently nebulized as standard treatments, the physicochemical environment of the diseased lung often limits their diffusion and overall effectiveness. Our previous studies showed polyelectrolyte surfactants (PS) to be a promising delivery system for cationic antimicrobials...

Welfare Indicators for Aquaculture Research: Toolboxes for Five Farmed European Fish SpeciesNARA Subscribed
Refining approaches to measuring, monitoring and appraising animal welfare in aquaculture research is key to (i) protecting and optimizing it, (ii) documenting the severity of how and when it deviates, and (iii) ensuring good scientific quality, reliable results and reproducibility, amongst other factors. However, different fish species and life stages can have varying welfare needs and assessing their welfare can be challengi...
Marine resources alter tundra food web dynamics by subsidizing a terrestrial predator on the sea iceNARA Subscribed
Predator use of resource subsidies can strengthen top‐down effects on prey when predators respond numerically to subsidies. Although allochthonous subsidies are generally transported along natural gradients, consumers can cross ecosystem boundaries to acquire subsidies, thereby linking disparate ecosystems. In coastal Arctic ecosystems, terrestrial predators like Arctic foxes ( Vulpes lagopus ) cross into the marine environmen...
Click beetles (Elateridae) identify conservation units in Oriental and European beech forestsNARA Subscribed
Beech trees form major parts of lowland temperate forests in the Western Palearctic. To protect biodiversity, many beech forests have been designated as World Heritage Sites or established as networks of beech forest reserves. However, the insect communities within these protected forests have not been well explored. In this study, elaterids (Elateridae, Coleoptera) in 26 beech forests, from France in the west to Iran in the e...
