The Asian sea bass, a marine fish, changes sex during itslifetime. The sea bass breeds in large groups, with fish ofboth sexes "broadcast spawning" in the same area --that is,they expel their gametes into the water rather than pairingoff. There does not seem to be any male-male competitionfor mating rights. Females spawn several times per seasonand males may fertilize the eggs of multiple females.

Concept explainers

Evolutionary adaptations

Evolutionary adaptation is the process through which organisms adapt or adjust to their surroundings to increase the chances of survival, mating, and reproduction. An organism's behavior, physiology, and structure are adjusted or changed to make it more suited to its environment.

Question

The Asian sea bass, a marine fish, changes sex during its
lifetime. The sea bass breeds in large groups, with fish of
both sexes "broadcast spawning" in the same area --
that is,
they expel their gametes into the water rather than pairing
off. There does not seem to be any male-male competition
for mating rights. Females spawn several times per season
and males may fertilize the eggs of multiple females. Do you
think that the sea bass are protandrous or protogynous?
Explain your answer in terms of the evolutionary advantages
of the strategy.

In 1983 a population of dark-eyed junco birds became established on the campus of the University of California, San Diego (UCSD), which is located many miles from the junco's normal habitat in the mixed-coniferous temperate forests in the mountains. Juncos have white outer tail feathers that the males display during aggressive interactions and during courtship displays. Males with more white in their tail are more likely to win aggressive interactions, and females prefer to mate with males with more white in their tails. Females have less white in their tails than do males, and display it less often. (Pamela J. Yeh. 2004. Rapid evolution of a sexually selected trait following population establishment in a novel habitat. Evolution 58[1]:166-74.) Refer to the paragraph on dark-eyed junco birds. The UCSD campus male junco population tails are about 36% white, whereas the tails of males from nearby mountain populations are about 40-45% white. The founding stock of UCSD birds was likely…

In a population of birds, males have long red tail feathers that they use in mating displays, and also sing in the mornings to attract females. You find that some males have more red feathers in their tails than others, while some sing for longer periods of time. In this bird species, a high proportion of eggs fail to hatch. You measure the number of eggs that successfully hatch that are fathered by each male bird, and find that the number of successful hatchlings is proportional to how long a male sings, but is unrelated to the amount of red in his tail. Question: Propose an explanation for why males evolved both to sing and to have red tails, and how females likely evolved in response to both traits.
