Recruitment in situ and fertility of nuclear phases of Gelidium robustum (Rhodophyta)

Recruitment in situ and fertility of nuclear phases of Gelidium robustum (Rhodophyta)

Plants of Gelidium robustum release spores all year long. However, recruitment is only observed in situ in summer. We demonstrate a significant difference in the survival of carpospores vs tetraspores with time (season); recruitment was detected in situ only at certain times of the year. The effect...

However, recruitment is only observed in situ in summer. We demonstrate a significant difference in the survival of carpospores vs tetraspores with time (season); recruitment was detected in situ only at certain times of the year. The effect of irradiance and temperature on the survival of G. robustum carpospores and tetraspores was evaluated and the results were related to recruitment experiments in situ. The results show that carpospore and tetraspore survival is different in the seasons of the year. Spring and summer presented the greatest survival (9% and 17%) and winter and autumn the lowest (1% and 4%). The variation in the survival of the spores in time agreed with that found in the recruitment, since the first recruits of 5 mm in length were detected in July (early summer). Las plantas de Gelidium robustum liberan esporas todo el año. Sin embargo, sólo se observa reclutamiento in situ en verano. Se demuestra que existe desigualdad en la supervivencia de carposporas vs tetrasporas en el tiempo (estaciones), lo cual repercute en que sólo en ciertas épocas del año se detecte reclutamiento in situ. Se examinó el efecto de la irradiancia y temperatura en la supervivencia de carposporas y tetrasporas de G. robustum y los resultados se relacionan con experimentos de reclutamiento in situ. Los resultados muestran que la supervivencia de carposporas y tetrasporas es diferente en las estaciones del año. La supervivencia fue mayor en primavera y verano (9% y 17%) y menor en invierno y otoño (1% y 4%). La variación de la supervivencia de las esporas en el tiempo concordó con lo encontrado en el reclutamiento, ya que los primeros reclutas de 5 mm de longitud se detectaron en Julio (principios de verano).
