Researchers used a mathematical model inspired by social media to show that winter warming could disrupt fish, according to a study published Monday in the journal Nature Climate Change.

The model showed the effects of warming winter waters on fisheries in the Mediterranean Sea, write Nicholas Clark of The University of Queensland School of Veterinary Science, Ceridwen Fraser of the University of Otago and James Kerry of James Cook University in the new study.

"Winter warming is occurring at a faster rate than summer warming for ecosystems around the world, but most studies focus on the summer," researchers wrote in the study.

"Here, we show that winter warming could affect coastal fish community compositions in the Mediterranean Sea using a model that captures how biotic associations change with sea surface temperature to influence species' distributions for 215 fish species," the researchers wrote

The three scientists found that the impact of warming water in the winter on species was on average four times greater than summer warming as it occurs more rapidly.

Clark said the social media inspired model helped them paint a more accurate picture than older climate change models.

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

Though winter warming has often been overlooked, Fraser said "winters are getting warmer too."

"Even though winter warming might not reach the extreme high temperatures of summer heatwaves, this research shows that warmer winters could also lead to ecosystem disruption, in some cases more than hotter summer warming will," he continued. "Our results suggest that winter warming will cause fish species to hang out together in different ways, and some species will disappear from some areas entirely."

Sixty percent of coastal Mediterranean grid cells are expected to lose fish by 2040, projections show.

"For the sake of marine ecosystems and the people whose livelihoods depend on them, we need to gain a better understanding of how ocean warming will influence both species and economies," Clark said.

A new look at deep-sea microbes
Newark DE (SPX) Jul 13, 2020
Microbial cells are found in abundance in marine sediments beneath the ocean and make up a significant amount of the total microbial biomass on the planet. Microbes found deeper in the ocean, such as in hydrocarbon seeps, are usually believed to have slow population turnover rates and low amounts of available energy, where the further down a microbe is found, the less energy it has available. A new study published out of a collaboration with the University of Delaware and ExxonMobil Research and E ... read more
