The mosaic of habitats in, on, or close to the seafloor – home to ninety eight% of all marine species – can also be getting decimated. Like very clear-slicing of an previous-progress forest, using significant, significant trawls dragged together the sea bottom to capture groundfish and also other species flattens and simplifies sophisticated, structured habitats such as gravels, coral reefs, crevices, and boulders and substantially decreases biodiversity.
Primary, these indicators really should, both singly or together, give info explicitly about living techniques. Measurements of Bodily or chemical factors can from time to time work as surrogates for immediate biological measurements, but only if the connection among Those people steps and living devices is clearly comprehended.
