Mollusk map (IMAGE) University of Nebraska-Lincoln Caption A map illustrating the occurrence of mollusks in marine shelf environments between 1700 and 2020, with darker hexagons indicating fewer and lighter indicating more. By compiling and analyzing mollusk fossil data from the past 145 million years, Nebraska's Will Gearty and colleagues have shown that temperature largely explains the diversity of aquatic life in the tropics. Human-driven global warming is expected to reduce that tropical biodiversity in coming centuries.
