Beschreibung:
Global climate change is a key driver of change in coastal waters with clear effects on
biological communities and marine ecosystems. Human activities in combination with
climate change exert a tremendous pressure on marine ecosystems and threaten their
integrity, structure, and functioning. The protection of these ecosystems is a major target
of the 14th United Nations sustainable development goal “Conserve and sustainably use
the oceans, seas and marine resources for sustainable development.” However, due to
the complexity of processes and interactions of stressors, the status assessment of
ecosystems remains a challenge. Holistic food web models, including biological and
environmental data, could provide a suitable basis to assess ecosystem health. Here,
we review climate change impacts on different trophic levels of coastal ecosystems
ranging from plankton to ecologically and economically important fish and shellfish
species. Furthermore, we show different food web model approaches, their advantages
and limitations. To effectively manage coastal ecosystems, we need both a detailed
knowledge base of each trophic level and a holistic modeling approach for assessment
and prediction of future scenarios on food web-scales. A new model approach with
a seamless coupling of physical ocean models and food web models could provide a
future tool for guiding ecosystem-based management.
