Published as: The effect of transplantation on reproduction in clonal ramets of Goniopora columna on Singapore's coral reefs. | Technique: Transplantation | Disturbance addressed: Land reclamation | Genera: Goniopora | Method: Ramets of the coral Goniopora columna were excised from five large colonies and transplanted within the same site and depth (2.3 m); to a more disturbed site closer to the mainland at a similar depth (2.2 m); and to greater depth at both sites (8.9 m and 7.6 m, respectively). Ramets were left for one year, then harvested before the predicted spawning periods. Fecundity (average number of oocytes polyp!1), reproductive effort (average oocyte diameter), and polyp tissue diameter were compared amo… | Post-restoration monitoring: 12 months | Authors' conclusion: Transplantation of ramets within site and to the same depth had no significant effect on reproductive effort, fecundity or polyp tissue diameter. Clonal fragments transplanted to the more disturbed site had significantly fewer oocytes, smaller oocytes and smaller polyps after one year suggesting that energy was diverted away from normal functions in response to stressors in the new environment. | This record was compiled from a published source and has not been confirmed by the organisation that carried out the work. No contribution to the condition index is recorded: the source reports survival of transplanted material, which is not a measure of ecosystem condition.

Recorded result

No result recorded yet. A result is recorded when the project moves to Paused, Completed or Discontinued.

A variable shows "pending" instead of a contribution when no domain area has been set for it yet — the share of the world a project touched cannot be computed without one. The health percentages are accurate regardless.
