Larval dispersal, recruitment, and adult distribution of the brooding stony octocoral Heliopora coerulea on Ishigaki Island, southwest Japan

Larval dispersal and recruitment are important
factors that determine the distribution of adult corals.
The relationships between larval dispersal, recruitment,
and the adult distribution of the blue octocoral, Heliopora
coerulea, were investigated on Shiraho Reef, Ishigaki
Island, southwest Japan. Heliopora coerulea is a
surface brooder that releases planulae in June or July on
Shiraho Reef. We observed planulae between 1998 and
2000 and found that they did not swim actively; instead,
they crawled into their settlement positions after
becoming grounded on the substratum. Planulae
occurred throughout the water column and were dispersed
by tidal and wind-driven currents around the
parent population on the reef flat. Recruitment was
observed only within 350 m of the parent populations,
including areas between the branches of the adult colony.
The planulae of H. coerulea had a narrow dispersal
range as a result of their mostly benthic, shorter larval
duration, and the influence of weaker currents. Thus, the
dispersal distance of larvae is determined by their position
in the water column, the currents that deliver the
larvae, and the competency period of the larvae. The
narrow dispersal range of H. coerulea was consistent
with recruitment

Heliopora coerulea (Alcyonaria, Coenothecalia), widespread since the Cretaceous, is today found in the Indo-Western Pacific between 25° N and 25° S but is uncommon throughout most of its range. Studies around its reported southern and eastern limits of distribution (Great Barrier Reef, Vanuatu, Fiji, Tonga, Western Samoa, Tuvalu, Gilbert Group) suggest that ocean temperature (a lower marginal isotherm of 22°C), duration of larval life-span, prevailing currents, and the geological and climatic history of isolated archipelagoes determine distribution. Heliopora was found to be far more abundant in the equatorial Central Pacific sites (Tuvalu and Gilbert growps) than in the Western Pacific (Great Barrier Reef, New Guinea, Solomon Islands, Ponape, Palau). Heliopora comprised up to 16% of beach sediments in Tuvalu atolls, and was the dominant coral (averaging 40% of substrate between 6 m and 10 m on reef slopes) in coral assemblages on Tarawa Atoll. From ecological studies in Tarawa it is suggested that competition from the more specialized and aggressive Scleractinia (particularly Acroporidae and Faviidae) is the major factor limiting abundance in the equatorial Western Pacific.

Heliopora is a genus of cnidarian in the monotypic family Helioporidae. It is a reef building hard coral but belongs to the subclass Octocorallia and is therefore most closely related to soft corals, sea pens, fan corals and sea whips and not to the main reef-building Scleractinian corals, which belong to subclass Hexacorallia. Currently only three species are known, one of which is known only from fossils:[1]

Heliopora: Brief Summary
(
Espanhol; Castelhano
)
fornecido por wikipedia ES
Heliopora es el único género de corales del orden Helioporacea, de la clase Anthozoa.
Este género actualmente es monoespecífico, contando con Heliopora coerulea (Pallas, 1766) como única especie existente, el "coral azul".
En los periodos de aguas templadas del océano Tetis, la familia Helioporidae era de las más dominantes, sobreviviendo tan sólo a las glaciaciones la única especie actual Heliopora coerulea.

Heliopora de Blainville, 1830 è un genere di octocoralli dell'ordine Helioporacea, che comprende due sole specie viventi. È l'unico genere della famiglia Helioporidae.[1]
Descrizione
Sono coralli ermatipici che costruiscono robuste strutture scheletriche di aragonite cristallina, simili a quelle degli esacoralli dell'ordine Scleractinia.[2]
I coralliti sono di colore azzurro in Heliopora coerulea, biancastri in Heliopora hiberniana; la struttura scheletrica è ricoperta da un cenenchima di colore brunastro.[3]
Distribuzione e habitat
Heliopora coerulea è ampiamente distribuita dal mar Rosso all'Indo-Pacifico occidentale;[2] l'areale di Heliopora hiberniana è ristretto alle acque dell'Australia nord-occidentale.[3]
Il loro habitat sono le barriere coralline tropicali di acque basse.
Tassonomia
Il genere comprende le seguenti specie viventi[1]:

Хеліопора (Heliopora) — рід восьмипроменевих коралів монотипної родини Хелопоридові (Helioporidae) ряду Хеліопораєві (Helioporacea).
Таксономія
Рід на даний час налічує тільки один вид Heliopora coerulea (Pallas, 1766), але колись включав ще два види, Heliopora carinata Pourtales, 1867 та Heliopora tubulatus Pourtales, 1867, було досліджено, що вони не належать до роду Хеліопора (Heliopora) і навіть належать до іншого класу, до Hydrozoa та підкласу Шестипроменеві корали (Hydroidolina). Внаслідок ці два види були переіменовані на Lepidopora carinata (Pourtalès, 1867) і Pliobothrus tubulatus (Pourtalès, 1867).
Єдиний живий вид роду: Синій корал (Heliopora coerulea, або Хеліопора синя) Pallas, 1766
