Climate change and marine ecosystems in the Arctic: Effects and what you need to know
Climate change and impacts on Arctic marine ecosystems
Climate change is strongly impacting Arctic marine ecosystems, causing significant changes in food webs and interactions between species. Recent studies have shown that ocean warming could lead to an increase in some species and a decline in others, affecting existing marine communities as well.
Changes in the food web
Researchers analyzed potential changes in local food webs in the Arctic due to climate change. Possible future scenarios include how changes in the abundance of one species in an area will affect other species, whether directly or indirectly interacting. Direct interactions, such as an increase in prey leading to an increase in the number of predators that eat them, are the most obvious responses in a food web. However, there can also be indirect responses where a change in one species can change the abundance of other species that do not seem to interact with it.
These changes could lead to significant declines in some important species in Arctic marine ecosystems, while also creating ripple effects across the entire food web.
The findings highlight the sensitivity of Arctic marine ecosystems to climate change and the need to reduce carbon emissions as quickly as possible.
