Male size composition affects male reproductive variance in Atlantic cod Gadus morhua L. spawning aggregations
Estimates of Atlantic cod Gadus morhua reproductive success, determined using experimental spawning groups and genetic paternity assignment of offspring, showed that within‐group variance in male size correlated positively with the degree of male mating skew, predicting a decrease in male reproducti...

Summary: | Estimates of Atlantic cod Gadus morhua reproductive success, determined using experimental spawning groups and genetic paternity assignment of offspring, showed that within‐group variance in male size correlated positively with the degree of male mating skew, predicting a decrease in male reproductive skew with decreasing size variation among males under natural conditions. |
