Life-history trade-offs among four sympatric seabreams
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: CG Attwood --- , South Africa HAM Ensair --- , South AfricaFish life history is shaped by environmental and ecological circumstances but constrained by phylogeny. Life-history trade-offs can be exposed in a comparison of closely related species with similar niches. We compare the life histories of four closely related and similar-sized,... -
