TLDR
It is reasoned that the delay response is elicited by an inhibitory factor released continually from Diplosoma, which is reversible, non-pathological, and species specific.Abstract:
In nature, the marine bryozoan, Bugula pacifica, is consistently the ‘loser’ when competing for space with the compound ascidian, Diplosoma macdonaldi. We provide laboratory evidence to show that Bugula larvae will delay settling in either ‘Diplosoma-conditioned water’ or an alcohol Diplosoma extract. It is reasoned that the delay response is elicited by an inhibitory factor released continually from Diplosoma. This response is reversible, non-pathological, and species specific. The possible ecological significance of larval avoidance behavior in this and other communities is discussed.read more

Role of early post-settlement mortality in recruitment of benthic marine invertebrates
TL;DR: Much of the present knowledge of the early postsettlement period has come from studies of barnacles and ascidians and more information is needed for other groups of benthic marine invertebrates, particularly mobile species.

Larval ecology of marine benthic invertebrates: paleobiological implications
David Jablonski,Richard A. Lutz +1 more
TL;DR: Studies of the larval ecology of fossil organisms can contribute greatly to the understanding of such roles by allowing us to race effects on evolutionary time scales.

Delayed metamorphosis by larvae of benthic marine invertebrates: Does it occur? Is there a price to pay?
TL;DR: The finding that various inorganic and organic substances can trigger the metamorphosis of benthic marine invertebrates is explored, and it is suggested that at least a few species delay meetingamorphosis in the field.

Marine natural product antifoulants: Status and potential
TL;DR: This overview attempts to bring together a widely scattered and disparate literature on marine natural product antifoulants, and studies that have focused on the screening of secondary metabolites are reviewed in the context of the development of new antifouling coatings.
Journal ArticleDOI
Field evidence that settling coral reef fish larvae detect resident fishes using dissolved chemical cues
TL;DR: It is suggested that some coral reef fish larvae use dissolved chemical cues to choose or to avoid settlement sites, as well as a number of other species, due either to selective settlement or to differential persistence.

Alleopathy and spatial competition among coral reef invertebrates
Jeremy B. C. Jackson,Leo W. Buss +1 more
TL;DR: Evidence suggests that alleochemical provide a wide-spread, specific, and complex mechanism for interference competition for space among natural populations of coral reef organisms.

Competitive Networks: Nontransitive Competitive Relationships in Cryptic Coral Reef Environments
Leo W. Buss,Jeremy B. C. Jackson +1 more
TL;DR: The existence of a competitive network on a particular substratum will serve to increase the length of time required for single species resource monopolization relative to the time required if a competitive hierarchy exists, assuming equivalent rates of overgrowth in both cases.

Resistance of a tunicate to fouling
TL;DR: Ascidia nigra is free of epibionts, although many other ascidians are susceptible to epizooic recruitment, and both the vanadium-rich surface deposit and the acid-filled capsules are believed to be formed by degenerating vanadocytes in the test.
Journal ArticleDOI
Inhibition of the Development of a Marine Sessile Community
TL;DR: A dense growth of sessile animals always developed on a panel, usually dominated by Balanus amphitrite and Didemnum maculosum, with smaller numbers of other ascidians (A. nigra, Diplosoma macdonaldi, Symplegma viride, Polyclinum constellatum).

Extrinsic factors influencing metamorphosis in bryozoan and ascidian larvae
TL;DR: It is a rather strange coincidence that so many different factors have similar effects in either inhibiting or accelerating the onset of metamorphosis in widely divergent groups, and the heavy metals seem to play a distinctive role.
