Natural history of Bimeria vestita Wright, 1859 (Hydrozoa, Bougainvilliidae) in the rocky intertidal of Mar del Plata (Argentina)

Natural history of Bimeria vestita Wright, 1859 (Hydrozoa, Bougainvilliidae) in the rocky intertidal of Mar del Plata (Argentina)

The population dynamics, reproductive period and substrate preference of the hydroid Bimeria vestita Wright, 1859 were analyzed from October 1990 to February 1992 in the rocky intertidal zone of Mar del Plata (Argentina). Colonies were found year-round, with maximun abundances in summer and autumn (...

Colonies were found year-round, with maximun abundances in summer and autumn (60% of the colonies). During these periods the colonies produce gonophores. Bimeria vestita is more frequently found on colonies of the hydroids Sertularella mediterranea Hartlaub, 1901 (58.1%) and Tubularia crocea (Agassiz, 1862) (37.5%) than on other substrates (4.4%). Seasonal differences in substrate preferences were observed. Tubularia crocea was the most preferred substrate in spring and summer (75–80%), while S. mediterranea was preferred in autumn and winter (70–80%). Stolonial growth of B. vestita suggests a "guerrilla" strategy to avoid competition in the basal zones of the substrates. Se analizó la dinámica poblacional, periodo reproductivo y utilización de sustratos del hidroide Bimeria vestita Wright, 1859 en el intermareal rocoso de Mar del Plata (Argentina) durante el periodo de octubre de 1990 a febrero de 1992. Las colonias se encontraron todo el año, aunque con una abundancia mayor en verano y otoño (60% de los hallazgos). Durante este periodo, las colonias producen gonóforos. Bimeria vestita habita sobre las colonias de los hidroides Sertularella mediterranea Hartlaub, 1901 (58.1%) y Tubularia crocea (Agassiz, 1862) (37.5%) más comúnmente que sobre otros sustratos (4.4%). Se detectaron diferencias estacionales en la colonización de los sustratos: en primavera y verano, T. crocea fue el sustrato más frecuente (75–80%) y en otoño e invierno, lo fue S. mediterranea (70–80%). El crecimiento estolonial de B. vestita sugiere una estrategia de "guerrilla" que evita la competencia que ocurre en las zonas basales del sustrato.
