More about the OA in Canada Species Impacts Series:
To summarize the current knowledge of OA impacts on species in Canada, the OA CoP has produced a poster series on how species are impacted by OA in Canada. The information presented here is based on the most current scientific literature (peer-reviewed, published papers) of studies conducted in Canada. We also highlight current gaps in our knowledge and areas that require additional research across Canada. These infographics are intended not only to highlight concerning OA impacts on important species in Canada, but are also meant to act as catalysts to support filling the gaps in our knowledge of OA impacts to species across Canada.
