QUINN, Norman J  y  KOJIS, Barbara L. Patterns of sexual recruitment of acroporid coral populations on the West Fore Reef at Discovery Bay,Jamaica. Rev. biol. trop [online]. 2005, vol.53, suppl.1, pp.83-90. ISSN 0034-7744.

Coral recruitment was examined on terracotta tiles deployed for four six-month periods between March 2001 and April 2003 on the West Fore Reef at Discovery Bay,Jamaica.During each sampling period, four tiles were deployed on each of two arrays at six depths ranging from 3 m to 33 m.Only three Acropora spat recruited to the tiles over the sampling period.The Acropora spat recruited during only one of the four six-month sampling periods and at only one depth,3m.That represents a density of 8 spat m^-2 at 3 m depth for one six-month sampling period.Acropora recruitment represented <1 %of the total spat recruiting to the tiles deployed at 3 m during the four sampling periods.Density of acroporids on the West Fore Reef is low.Only one Acropora colony (an A.palmata )was recorded during Point-Quarter surveys of coral cover and density at depths of 3 m,9 m,14 m and 19 m.Considering the paucity of acroporid colonies and the infrequent settlement of acroporid spat on the West Fore Reef,it is unlikely that the historic abundance of A.palmata and A. cervicornis will return soon.
