- Abstract: Rhizophora mangle is the most common species of mangrove within its range and a major component of coastal ecosystems in the tropics and subtropics. Its phenology is affected by seasonal variations in temperature, salinity, and precipitation, all of which may be altered by impending climate change. In this work, the monthly leaf, flower, and fruit phenology of R. mangle was assessed at three sites, along a natural salinity gradient for 12 months. We assessed phenological states using litter traps installed in mangrove stands, and by direct observation of leaf production at two sites, and flower, and fruit production at a single site. Phenological events were compared with seasonal climatic variations (in wind, rain, and temperature) to explore potential abiotic controls on the phenology of this species. Leaf shedding was lowest at the low salinity site. Leaf and stipule production showed a seasonal trend, decreasing during the cool and dry winter months. Flowering was highly seasonal and synchronous and peaked during the rainy season. Flowering was correlated with average temperature ( r = 0.82; p < 0.05) at all three study sites, but was not correlated with precipitation. At the high‐salinity site, flowering was restricted to the rainy season. Fruit abortion was associated with wind speed ( r = 0.79; p < 0.05). Flowering of R. mangle is induced by increasing temperatures and the onset of rains.

Resumen: Rhizophora mangle es la especie más común dentro de su distribución y de importancia para el funcionamiento del ecosistema. Su fenología muestra variaciones estacionales relacionadas con la temperatura, la salinidad y la precipitación, que pueden alterarse por el inminente cambio climático. Se evaluó la producción de hojas, flores y frutos de R. mangle, en tres sitios con diferentes condiciones de salinidad, a lo largo de un gradiente salino natural, y se relacionaron los eventos fenológicos con el clima (viento, lluvia, temperatura) durante un período de 12 meses, para describir su efecto sobre la fenología de esta especie. Se instalaron trampas de hojarasca en tres poblaciones de mangle con salinidades contrastantes y se hicieron observaciones directas sobre la producción de hojas, flores y frutos. La caída de hojas fue menor en el sitio de baja salinidad, y mostró un patrón estacional con decremento durante el invierno. La floración fue altamente estacional, sincrónica y alcanzó su máximo durante la temporada de lluvias, correlacionándose con el aumento en la temperatura ( r = 0.82, p < 0.05), pero no fue favorecida directamente por la precipitación. En el sitio de alta salinidad, la floración se limitó a la estación lluviosa. El aborto de frutos se asoció con la velocidad del viento ( r = 0.79; p < 0.05). La floración de R. mangle es inducida por el aumento de las temperaturas y favorecida por el comienzo de las lluvias. El incremento de las temperaturas, veranos más secos y tormentas más frecuentes e intensas, como consecuencia del cambio climático, pueden tener efectos sobre la productividad la dinámica poblacional y la sincronía floral del manglar. … (more)
