Life in the 'hothouse' may be precarious for marine species

By Jim Shelton May 13, 2021 Share this with FacebookShare this with TwitterShare this with LinkedInShare this with EmailPrint this (© stock.adobe.com) The rise and fall of marine mollusks during ancient “hothouse” periods may offer a jarring glimpse of the fate of marine life over the next few centuries, a new study says. Writing in the journal Current Biology, researchers at Yale, Stanford, and the University of Nebraska-Lincoln say mollusks such as clams, sea snails, and cephalopods will be particularly vulnerable in tropical regions if global climate projections hold true.  The researchers analyzed 145 million years’ worth of data, in increments of approximately 10 million years. They looked at geochemical data that reveal past ocean temperatures, fossil data of mollusks, and models for habitability and biodiversity.

Study indicates global warming could reduce biodiversity in tropics

Study indicates global warming could reduce biodiversity in tropics New research by the University of Nebraska-Lincoln suggests that temperature can largely explain why the greatest variety of aquatic life resides in the tropics but also why it has not always and, amid record-fast global warming, soon may not again.ANI | Washington DC | Updated: 07-05-2021 10:13 IST | Created: 07-05-2021 10:13 IST Representative Image.

The bulging, equator-belted midsection of Earth currently teems with a greater diversity of life than anywhere else - a biodiversity that generally wanes when moving from the tropics to the mid-latitudes and the mid-latitudes to the poles.

The bulging, equator-belted midsection of Earth currently teems with a greater diversity of life than anywhere else - a biodiversity that generally wanes when moving from the tropics to the mid-latitudes and the mid-latitudes to the poles. Published in the journal Current Biology, the study estimates that marine biodiversity tends to increase until the average surface temperature of the ocean reaches about 65 degrees Fahrenheit, beyond which that diversity slowly declines.
