Social media inspired models show winter warming hits fish stocks

University of Queensland School of Veterinary Science researcher Dr. Nicholas Clark and colleagues from the University of Otago and James Cook University have assembled a holistic picture of climate change’s impacts on fish stocks in the Mediterranean Sea.

“Usually, when modeling ecosystems to understand how nature is changing, we build models that only focus on the effects of the environment,” Dr. Clark said.

“But it’s just not accurate enough.

“Newer models—commonly used in social media to document people’s social interactions—offer an exciting way to address this gap in scientific knowledge.

“These innovative network models give us a more accurate picture of reality by incorporating biology, allowing us to ask how one species responds to both environmental change and to the presence of other species, including humans.”The team used this technique to analyze fish populations in the Mediterranean Sea, a fisheries-based biodiversity hotspot with its future under threat from rapidly warming seas.”Experts from fisheries, ecology and the geographical sciences have compiled decades of research […]
