We repeated this analysis for a larger data set consisting of all females wit h brood pouches containing parthenogenetic eggs or embryos (Table 1b).
"The brood pouches would have helped young trilobites survive."
The proximate aims are to identify the numbers of females who have contributed eggs to each male's brood; assess the spatial position within brood pouches of multiply mothered clutches of embryos; assess the possibility of cuckoldry by males (as a test of a theoretical prediction that the evolution of high investment in offspring by males is facilitated by an assurance of genetic paternity; Smith 1979); reveal how often individual females distribute batches of eggs to more than one male; and compare all outcomes with those previously reported by Jones and Avise (1997) for a sympatric congener that is more dimorphic in secondary sexual characters, the Gulf pipefish S.
In an intermediate position on the continuum are external brooders or species in which the brood structure is open to seawater (e.g., bursal brooding in ophiuroids, brood pouches).
When juveniles are ready to feed (with the opening of the stomodeum 254 days after fertilization), they leave the brood pouches. This is equivalent to the settlement of the young juvenile that develops from a planktotrophic larva; settlement occurs weeks to months after fertilization (Emlet et al., 1987).
