A new study shows how changes in marine communities tightly follow ocean warming as the number and abundance of warm-water species increase whereas those of cold-water species decrease. <\/p>\n\n\n\n

Anticipating changes in community composition\nin response to warming is challenging because species respond differently and\nthe interactions change between them. However, a new study published in\u00a0Nature\nClimate Change<\/em>\u00a0shows how changes in marine communities tightly\nfollow ocean warming as the number and abundance of warm-water species increase\nwhereas those of cold-water species decrease.<\/p>\n\n\n\n

\u201cIdentifying\naspects of community change that can be monitored and forecasted is crucial to\nbetter inform management to environmental changes,\u201d explains Jorge Garc\u00eda\nMolinos of Hokkaido University\u2019s Arctic Research Center, one of the authors of\nthis study.<\/p>\n\n\n\n

Led by\nProfessor Michael Burrows of the Scottish Association for Marine Science\n(SAMS), an international team of researchers from the UK, Japan, Australia,\nUSA, Germany, Canada, South Africa and New Zealand analysed three million\nrecords of thousands of species from standardized international surveys dating\nback to 1985 to assess how ocean warming is affecting the composition of fish\nand plankton communities across the northern hemisphere in relation to the\nthermal tolerances of their constituent species.<\/p>\n\n\n\n

In\nrapidly warming waters, like the North Atlantic, the team found strong shifts\ntowards a dominance of warm-water species, replacing their cold-tolerant\ncounterparts. These changes were less pronounced in regions with stable\ntemperatures, including the Northeast Pacific and the Gulf of Mexico. Marine\ncommunities most sensitive to warming are composed of species with diverse\nthermal preferences and narrow thermal tolerance ranges.<\/p>\n\n\n\n

However,\nin some regions experiencing rapid surface warming, like the Labrador Sea,\ncommunities were less responsive than expected. These regions are characterized\nby strong temperature depth gradients (up to 5\u00b0C for 100m depth), allowing some\nof the cold-water species to cope with warming by redistributing towards deeper\nwaters.<\/p>\n\n\n\n

\u201cThis\nfinding reminds us that life in the ocean, and the impacts of climate change on\nit, span a truly three-dimensional world. Yet, we still tend to simplify the\nsituation by looking at these issues in two dimensions, something that may lead\nto the wrong conclusions,\u201d Garc\u00eda Molinos says.<\/p>\n\n\n\n

The scientists say these strong, predictable effects of recent temperature change on marine community composition, operating through species thermal affinities, provide a benchmark for measuring how fast global biodiversity is restructuring itself as a result of climate change on regional to ocean scales.\u00a0<\/p>\n\n\n\n
