Evolutionary transitions, environmental correlates and life-history traits associated with the distribution of the different forms of hermaphroditism in fish

Abstract

[CAT] Un sistema sexual es defineix com el patró de distribució de la funció masculina i femenina que existeix en una espècie donada, que pot tenir lloc en individus separats (gonocorisme) o al mateix individu (hermafroditisme). En els hermafrodites, la funció masculina i femenina pot ocórrer simultàniament o seqüencialment: masculí primer (proteràndria) o femení primer (protogínia). Comprendre les transicions evolutives entre els diferents sistemes sexuals, així com les correlacions amb factors biòtics i abiòtics que expliquen la seva distribució entre els taxons, és un gran desafiament en la biologia evolutiva. Es va estudiar la incidència, la distribució i les transicions evolutives entre els diferents sistemes sexuals en peixos actinopterigis, l'únic grup de vertebrats on l’hermafroditisme és present. Per a això, es va recopilar informació sobre el sistema sexual, les correlacions ambientals i els trets del cicle vital en 10.875 peixos. Posteriorment, es van aplicar mètodes filogenètics moderns per reconstruir l'estat sexual ancestral. [...]

[EN] A sexual system defines the pattern of distribution of male and female function that exists in a given species, which can occur in separate individuals (gonochorism) or in the same individual (hermaphroditism). In hermaphrodites, male and female function can happen simultaneously or sequentially: male first (protandry) or female first (protogyny). Understanding the evolutionary transitions among the different sexual systems as well as the biotic and abiotic correlates that explain their distribution among taxa is a major challenge in evolutionary biology. The incidence, distribution and evolutionary transitions among the different sexual systems were studied in actinopterygian (ray-finned) fishes, the only group of vertebrates where hermaphroditism is present. To this end, information was compiled on the sexual system, environmental correlates and life-history traits of 10,875 ray-finned fishes. Then, modern phylogenetic methods were applied to reconstruct the ancestral sexual state. [...]
