“…While this hypothesis has been criticised, it is weak only in its attempt to suggest that timing makes it more likely for the male to provide care (Loiselle 1978, Baylis 1978, Blumer 1979. Actually, timing is important in that both sexes are present at the time of zygote formation, rather than just one sex as is true for internal fertilization.…”

“…This line of reasoning has recently been extended to explain the phenomenon of paternal fishes (Loiselle 1978, Loiselle & Barlow 1978and Perrone & Zaret 1979. Loiselle & Barlow (1978) and Loiselle (1978) noted that a territorial male defends a limited resource, the spawning site.…”

“…Most authors discussing territorial behavior and the evolution of parental behavior in fishes have emphasized the territory as a resource required for spawning (Barlow 1964, Williams 1975, Ridley 1978, Loiselle 1978, Baylis 1974, Loiselle & Barlow 1978, Blumer 1979. Most have followed Barlow's lead in attributing the territorial role to the male because of the male's greater potential for multiple mating.…”

“…. the differential energetic unit-cost of producing ova and spermatozoa,' (Loiselle 1978) they argued that the male was better able to provide parental care at the site. A similar argument has been presented for the occurrence of maternal and paternal parental care among inshore fishes (Qasim 1956).…”

SynopsisA simple two part hypothesis is proposed to describe the sources of selection influencing the evolution of parental care in fishes. It is derived in part from the observation that most fishes exhibiting complex patterns of parental behavior are freshwater forms. The first aspect of the hypothesis assumes that differential zygote mortality occurs in spatially and temporally varying environments. The second assumes that rates of gametogenesis are faster in males than in females. These aspects interact to generate a series of predictions: 1. When the zygote requires an external resource such as an optimal site for development, and that resource is scarce relative to the breeding population and is reusable, the male should monopolize it (male reproductive territoriality). 2. When bearing is derived from male guarding, the male will be the bearer. 3. When bearing evolves from a condition other than male guarding, the female will be favored as the bearer and the male will be favored as the gamete donor. 4. In all of the above cases except male bearing, the male's reproductive success is limited primarily by the number of females he can attract rather than his own rate of gamete production and hence the male will tend to be the sexually selected sex. These and other predictions are tested against the existing literature on reproduction in fishes, and competing hypotheses are critically reviewed.

SynopsisCoral-reef fishes have been selected to produce propagules for dispersal because they live in a patchy environment, and the adults cannot migrate between patches. For large species ( > 100 mm SL) and widely separated patches, numerous propagules are needed, often with specialized pelagic intervals. Individuals of small species are confined to portions of the reef. They are unable to produce enough eggs for effective longrange dispersal, and so they keep their vulnerable eggs and young out of the plankton until they are well developed enough to seek out and settle onto the appropriate habitat before dispersing.Guarded demersal eggs, requiring a greater individual investment by the small short-lived species, further reduces their individual fecundity. These costs to fecundity, and the reduction in vagile young appear to account for the lack of postzygotic investment in larger longlived species.All coral-reef fishes are selected to disperse, usually with a young planktonic propagule interval. Both large and small species produce a mixed outcome, with some propagules returned to, or retained at the home reef, while others disperse more widely. The smaller the species the greater the proportion of propagules retained.
