Reproductive pattern of the reef-building coral Pavona gigantea (Scleractinia: Agariciidae) off southwestern Mexico

The reproductive biology of the massive coral Pavona gigantea has been studied along Mexico’s Pacific coast, but basic aspects such as its relation to local environmental variables and its variation on a mesoscale level have not been addressed. The reproductive cycle of P. gigantea was monitored mon...

The reproductive cycle of P. gigantea was monitored monthly over a two-year period (2010–2012) at four sites along the coast of Oaxaca (southwestern Mexico). Except for one hermaphroditic colony, P. gigantea was gonochoric and exhibited asynchronous development. The data suggest that, in the study area, the species may reproduce seasonally, with minor interannual differences (May–September 2010, April–August 2011, April–May 2012). There were spatial and temporal variations in the percentage of reproductively active colonies and the presence of mature sex cells. A multiple regression analysis revealed that the percentage of reproductively active colonies was significantly explained (69.6%) by mesoscale variations in environmental variables such as sea surface temperature, photosynthetically active radiation, diffuse attenuation coefficient, percentage of lunar illumination, and photoperiod, the latter being the most relevant variable in the model. The data suggest that temporal mesoscale variations can exert a meaningful influence on coral reproduction in the study area.  La biología reproductiva del coral masivo Pavona gigantea en las aguas del Pacífico frente a las costas mexicanas ha sido estudiada; sin embargo, algunos aspectos básicos, como su relación con factores abióticos locales y su variación a nivel de mesoescala, no han sido resueltos. Se monitoreó el ciclo reproductivo de P. gigantea durante dos años (2010–2012) en cuatro localidades frente a la costa de Oaxaca, sudoeste de México, en el Pacífico. Pavona gigantea presentó colonias gonocóricas con desarrollo asincrónico y una colonia hermafrodita. Los datos sugieren que la especie podría reproducirse de manera estacional con variaciones interanuales (mayo–septiembre de 2010, abril–agosto de 2011, abril–mayo de 2012). Se observaron variaciones espaciotemporales en el porcentaje de colonias con actividad reproductiva y en la presencia de gametos maduros. El modelo de regresión lineal múltiple sugiere que las variaciones ambientales a mesoescala de temperatura superficial oceánica, radiación fotosintéticamente activa, coeficiente de atenuación difusa, porcentaje de iluminación lunar y fotoperiodo explicaron significativamente el 69.6% de la variación en el porcentaje de colonias con actividad reproductiva, y el fotoperiodo fue la variable más importante en el modelo. Los datos indican que las variaciones temporales a mesoescala podrían influenciar la reproducción de las especies de coral en el área de estudio. 2015-09-21 2021-06-03T03:55:25Z 2021-06-03T03:55:25Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Artículo Arbitrado https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2482 10.7773/cm.v41i3.2482 https://hdl.handle.net/20.500.12930/7477 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/2482/1565 Copyright (c) 2015 Ciencias Marinas application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 41 No. 3 (2015); 233-246 Ciencias Marinas; Vol. 41 Núm. 3 (2015); 233-246 2395-9053 0185-3880
