Temporal variation in the regeneration rate of artificial lesions in two morphotypes of Porites panamensis

The regeneration of artificial lesions in the columnar and massive forms of the nominal taxon Porites panamensis was compared, in order to contribute to the knowledge of the physiology of the species complex and to help clarify the taxonomic situation of the phenoms.

Temporal variation in the regeneration rate of artificial lesions in two morphotypes of Porites panamensis
description The regeneration of artificial lesions in the columnar and massive forms of the nominal taxon Porites panamensis was compared, in order to contribute to the knowledge of the physiology of the species complex and to help clarify the taxonomic situation of the phenoms. The study was carried out at Punta Gaviotas (24º17.134′N, 110º19.870′W) and Punta Galeras (24º21.236′N, 110º17.028′W), in La Paz Bay, Mexico. One circular lesion per colony (0.70 ± 0.09 cm diameter and 0.5 cm deep) was inflicted on 26 to 30 colonies at each site and the regeneration rate was compared during the cold season (19–22ºC, March–April 2004) and the warm season (28–30ºC, September–October 2004). The regeneration rate followed a negative exponential model for both forms of P. panamensis in both seasons, but the process was faster in the warm season than in the cold season, probably due to increased light availability for zooxanthellae at that time of year. We observed differences in the percentage of full regeneration between forms during the warm season and in the proportion of colonies invaded by algae in the lesion area, the massive form showing three times more damage than the columnar in both seasons. As the morphotypes of P. panamensis showed the same regeneration rate, it is suggested that they might represent the same species; however, the differences in susceptibility to algal colonization and in the percentage of complete recovery of the colonies might indicate a selective advantage of the columnar form over the massive one.

Se comparó la capacidad de regeneración del daño provocado por lesiones artificiales entre las formas columnar y masiva del taxón nominal Porites panamensis, con el fin de contribuir al conocimiento de la fisiología del complejo de especies y ayudar a aclarar la situación taxonómica de sus formas. El estudio se realizó en Punta Gaviotas (24º17.134′N, 110º19.870′W) y Punta Galeras (24º21.236′N, 110º17.028′W), Bahía de La Paz, México. Se realizó una lesión circular por colonia a entre 26 y 30 colonias por localidad (diámetro de 0.70 ± 0.09 cm y profundidad de 0.5 cm) y se comparó la tasa de regeneración durante la temporada fría (19–22ºC, marzo a abril de 2004) y la cálida (28–30ºC, septiembre a octubre de 2004). La tasa de regeneración tuvo un comportamiento exponencial negativo para ambas formas en las dos estaciones del año estudiadas. El proceso fue más rápido en la temporada cálida que en la fría, probablemente debido a la mayor disponibilidad de energía lumínica para las zooxantelas en esa temporada. Se observaron diferencias en los porcentajes de regeneración completa entre las formas en la temporada cálida, y en la proporción de las colonias que presentaron fijación algal en las lesiones; la masiva mostró un daño tres veces mayor que la columnar en ambas temporadas. Como las formas de P. panamensis presentaron la misma tasa de regeneración, se sugiere que probablemente representen una misma especie. Sin embargo, las diferencias en la susceptibilidad a la colonización por algas y en el porcentaje de regeneración completa de las colonias, podrían significar una ventaja selectiva de la forma columnar. 2006-05-24 2021-06-03T03:55:07Z 2021-06-03T03:55:07Z info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed research note Nota de investigación arbitrada https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1027 10.7773/cm.v32i12.1027 https://hdl.handle.net/20.500.12930/7385 eng https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/1027/930 application/pdf Iniversidad Autónoma de Baja California Ciencias Marinas; Vol. 32 No. 1B (2006); 187-194 Ciencias Marinas; Vol. 32 Núm. 1B (2006); 187-194 2395-9053 0185-3880
