Seasonal biomass variation of Chondracanthus canaliculatus (Rhodophyta, Gigartinales) associated with environmental factors, using a principal components analysis

Associations between biomass (dry weight) of Chondracanthus canaliculatus (Harvey) Guiry and atmospheric and seawater temperature, wave energy and hours of tidal emersion were determined using a principal components analysis. Bimonthly samples of C. canaliculatus biomass were collected from November...

Bimonthly samples of C. canaliculatus biomass were collected from November 1988 to November 1989, Chondracanthus canaliculatus biomass had a marked seasonal cycle, with maximum values of biomass in summer (670 g m–2) and minimum in winter (126 g m–2). The principal components analysis showed that high biomass (grater than 543 g m–2) was associated with high atmospheric temperatures (greater than 21.4ºC) and low wave energy (less than 95.7 cm). Low biomass (less than 323 g m–2) was associated with low atmospheric temperatures (less than 17.2ºC) and tidal emersion between 81.5 and 109 h. Medium biomass values (323-543 g m–2) were associated with high water temperatures (grater than 16ºC). Se determinaron las asociaciones entre la biomasa (peso seco) de Chondracanthus canaliculatus (Harvey) Guiry y la temperatura atmosférica y del agua, energía del oleaje y horas de exposición debidas a la marea, utilizando un análisis de componentes principales. Se tomaron muestras bimensuales de biomasa de C. canaliculatus desde noviembre de 1988 hasta noviembre de 1989. La biomasa de C. canaliculatus presentó un marcado ciclo estacional, con biomasa máxima en verano (670 g m–2) y mínima en invierno (126 g m–2). El análisis de componentes principales reveló que la biomasa alta (mayor que 543 g m–2) quedó asociada con temperaturas atmosféricas altas (mayor que 21.4ºC) y baja energía del oleaje (menor que 95.7 cm). La biomasa baja (menor que 323 g m–2) estuvo asociada con temperaturas atmosféricas bajas (menor que 17.2ºC) y tiempo de exposición al aire entre 81.5 y 109 h. Los valores de biomasa intermedios (323-543 g m–2) estuvieron asociados con temperaturas del agua altas (mayor que 16ºC).
