Male mate choice is rarely studied or observed in many species but multiple studies have confirmed male mate choice within stickleback species. Males show a choosiness similar to females as to what female they are willing to court and mate. Male sticklebacks have been observed to show preference towards female sticklebacks that are larger and ...
He approaches a female by swimming very short distances left and right, and then swims back to the nest in the same way. If the female follows, the male often pokes his head inside the nest, and may swim through the tunnel. The female then swims through the tunnel as well, where she deposits 40–300 eggs. The male follows to fertilize the eggs.
During the breeding season (April to July), the male builds a nest suspended on a piece of waterweed, about an inch or so above the substrate at the bottom. The female is attracted by the male and she lays eggs inside the nest, but then departs, leaving parental care to the male. The male guards these eggs and the young fry when they hatch.
After spawning, the male assumes protection of the eggs which hatch in 7–11 days. [15] New hatched stickleback can wander from the nest, but the male gathers them into his mouth to deposit them back in the protective nest. Spawning usually ends around mid-July due to swift temperature changes in the water.
Bell studied the gene expression of male sticklebacks before and after becoming fathers, at three points of the hatching process. [7] She found an overlap between the genes associated with parental care in stickleback fathers and those of maternal mice. In 2020, Bell was elected a Fellow of the American Association for the Advancement of ...
A second hypothesis is that the stickleback distraction display arose from displaced foraging behavior and as such represents faux-foraging. [8] In support of this hypothesis was the finding that all-male, all-female, and mixed foraging groups responded equally to the display, which would not be expected if it were indeed mimicking a sexual ...
The blackspotted stickleback (Gasterosteus wheatlandi) is species of ray-finned fish belonging to the family Gasterosteidae, the sticklebacks. This fish is found in the western Atlantic from the coasts of Newfoundland (Canada) to Massachusetts (United States). This is a benthopelagic species of marine and brackish waters, rarely entering ...
Pungitius hellenicus, the Greek ninespine stickleback or ellinopygósteos, is a species of fish in the family Gasterosteidae. It is endemic to Greece. Its natural habitats are rivers and freshwater spring. It is threatened by habitat loss and considered critically endangered in the International Red List of IUCN, Bern Convention (Appendix III).
