Bowhead whale faeces link increasing algal toxins in the Arctic to ocean warming
Over the last two decades, ocean warming and rapid loss of sea ice have dramatically changed the Pacific Arctic marine environment1–3. These changes are predicted to increase harmful algal bloom prevalence and toxicity, as rising temperatures and larger open water areas are more favourable for growth of some toxic algal species4. It is well known that algal toxins are transferred through food webs during blooms and can have negative impacts on w…
International writing.- In recent decades, the warming of the oceans and the rapid loss of sea ice have drastically changed the Arctic marine environment. These new conditions are favoring the flowering of harmful algae that produce toxins that can have harmful effects on ecosystems and humans. Today, a study led by the Seattle (United States) NOAA Fisheries has discovered the direct relationship between the increase in algae toxins entering the…
