Intra‐ and interspecific density‐dependent growth and maturation of Pacific salmon in the Bering Sea
Abstract Many studies have reported density‐dependent growth in single species, but density‐dependent growth can also occur between species when overlap in resource use occurs. We interrogate long‐term (1972–2010) monitoring data from the Bering Sea for evidence of intra‐ and interspecific density‐d...
