Environment outweighs the effects of fishing in regulating demersal community structure in an exploited marine ecosystem ArchiMer
Mérillet, Laurene; Kopp, Dorothee; Robert, Marianne; Mouchet, Maud; Pavoine, Sandrine.
Global climate change has already caused bottom temperatures of coastal marine ecosystems to increase worldwide. These ecosystems face many pressures, of which fishing is one of the most important. While consequences of global warming on commercial species are studied extensively, the importance of the increase in bottom temperature and of variation in fishing effort is more rarely considered together in these exploited ecosystems. Using a 17‐year time series from an international bottom‐trawl survey, we investigated co‐variations of an entire demersal ecosystem (101 taxa) with the environment in the Celtic Sea. Our results showed that over the past two decades, biotic communities in the Celtic Sea were likely controlled more by environmental variables...
