Synthesis of life history information in scombrid species.

<p>Number of estimates for each life history trait within the main four taxonomic groups of scombrids (tunas, bonitos, Spanish mackerels and mackerels). Within each taxonomic group, the species are plotted in ascending rank order of body size, with the smallest species at the bottom (See <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070405#pone-0070405-t001" target="_blank">Table 1</a> for maximum body size). The Butterfly kingfish (<i>Gasterochisma melampus</i>), the only species in the subfamily Gasterochismatinae, is not included. The only life history trait recorded for this species is maximum length, being 195 cm <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0070405#pone.0070405-Kohno1" target="_blank">[59]</a>. The area of the grey circles is proportional to the number of estimates available for each trait.
