The following is cross-posted from the symposium website: The 5th Symposium on the Ocean in a High-CO2 World is being organized by the Pedro Ruiz Gallo National University in cooperation with the International Atomic Energy Agency (IAEA). This Symposium follows the symposia in Paris in 2004, Monaco in 2008, Monterey in 2012, and Hobart in 2016, which were all key events for the international community of researchers studying ocean acidification and related stressors. The 5th symposia will maintain the traditional focus of the four previous symposia and look at ocean acidification and associated impacts on marine organisms, ecosystems, and biogeochemical cycles. Ocean acidification will be considered in combination with other global changes such as warming and deoxygenation. The Symposium is inter-disciplinary and contributions are expected to detail advances in observations, modelling, field and laboratory studies.

Critter Fun Facts: Red sea stars are considered a keystone species as they have no natural predators. They control the populations of their prey species from growing too large for the ecosystems where they are found. Like many other Echinoderms, red sea stars move with tube feet which move which are powered by a hydrostatic skeleton, which uses fluid-filled chambers to flex and move. These tube feet also help with eating, by transferring food along the underside of the sea star towards the mouth. OA Impact: Ocean Acidification reduces the growth of red sea stars, leading to an overall negative effect on this important Atlantic keystone species. Diet: Red starfish are predators and since they can't swim all of their prey lies on the seafloor, such as: mussels & bivalves, other sea stars, barnacles, snails, and when they come across dead creatures on the seafloor, they act as opportunistic scavengers. Predators: None Habitat: The red sea star's preferred habitat is on a rocky/gravel bottom, since these critters can tolerate a wide array of environmental factors they inhabit both shallow and deep water ecosystems. Geographic Distribution: The North American distribution of the red sea star ranges from Labrador south to the Gulf of Mexico on the Atlantic Coast. The red sea star has also been reported in the Arctic Ocean. To see the North American distribution on the Map of Canada's OA Resources by clicking here! The South American distribution continues the North American Atlantic distribution to Northern Brazil. These stars are also widespread across the European Atlantic coast, as well as, the Northern African Atlantic coast. Linnaean Classification: Kingdom: Animalia Phylum: Echinodermata Subphylum: Asterozoa Class: Asteroidea Subclass: Ambuloasteroidea Infraclass: Neoasteroidea Superorder: Forcipulatacea Order: Forcipulatida Family: Asteriidae Genus: Asterias Species: rubens Etymology: Asterias is Latin for stars, rubens is Latin for blushing. The name Asteria rubens translates roughly to "Blushing Stars" Common Names: common starfish, common sea star, sugar star, Atlantic red sea star If you want to see any other critters featured in this blog let us know by emailing coordinator@oceanacidification.ca!

Critter Fun Facts: Softshell clams are common on both the Pacific and Atlantic coasts of Canada but are an invasive species in Canadian Pacific waters. These clams can grow up to 3 to 4 inches in length and reach a maximum of 1/4 pound (0.1kgs). If you are ever walking along a Canadian beach at low tide and something squirts you with water from the sand, this is a softshell clam! When they are disrupted, they shoot water from where they are buried through their siphon and into the air! Economic: Softshell clams and clams in general are an important part of Canada's shellfish industry. In 2020, the DFO reported that 4022 metric tonnes of clams were reported as landings from fisheries that year, which generated $121109 000. OA Impact: Negative: Sediment acidification has negative effects on burrowing. This is predicted to increase dispersal to other, potentially unfavourable habitats. However, sediment pH may influence juvenile clam abundances. However, this effect could be from sediment grain size. Future work will be needed to determine this. CO2 effects on neurophysiology (GABAA receptors) can act to mediate adaptive behaviors in juvenile marine bivalves to elevated CO2, but these behaviors may be negatively affected by elevated temperature. Diet: Softshell Clams are suspension feeders and deposit feeders (this means they will eat almost any food in the water or the surrounding substrate). Predators: Crabs, horseshoe crabs, diving ducks, and rays are all predators of adult clams. Juvenile clams have many more predators due to their small size and their planktonic form (softshell clams' adult form is buried and not buried in the substrate). Habitat: Softshell clams live in the sandy intertidal zone. Clams burrow down into the substrate, some as deep as 12 inches. Geographic Distribution: Soft shell clams are found on the East Coast and West Coasts of Canada. Click here to view the approximate distribution on the Map of OA Resources. Linnaean Classification: Kingdom: Animalia Phylum: Mollusca Class: Bivalvia Subclass: Autobranchia Infraclass: Heteroconchia Subterclass: Euheterodonta Superorder: Imparidentia Order: Myida Superfamily: Myoidea Family: Myidae Genus: Mya Species: arenaria Etymology: arenaria means sandy. Mya is probably an alteration of the Ancient Greek word for mussel. Put together the softshell clams name means something along the lines of Sandy Mussel. Common Names: steamer clam, steamer, soft-shelled clam, softshell clam, softshell, Smooth butter clam, sand gaper, Manila clam, long-necked clam, and large-neck clam.
