Exploration of benthic foraminifera community in sediment of three cuban mesophotic reefsAbstract
Los arrecifes coralinos están entre los ecosistemas marinos más amenazados por el hom- bre y el cambio climático sin embargo, los arrecifes mesofóticos han sido poco estudiados, debido a que las profundidades en las que se encuentran adicionan dificultades para su estudio, aunque en los últimos años han sido de mayor interés para la ciencia a partir de la teoría de que la profundidad los protege de los factores de estrés regionales y globales que afectan a los arrecifes “someros”. Por ello, se realizó una expedición conjunta Cuba- Estados Unidos en el año 2017, con el objetivo de mapear y documentar el alcance y la salud de los arrecifes de coral mesofóticos a lo largo de toda la costa de Cuba. En dicho viaje, se extrajeron 3 muestras de sedimentos de 3 arrecifes mesofóticos diferentes, con el objetivo de explorar la comunidad foraminíferos de bentónicos. Se identificaron 14 es- pecies de foraminíferos como nuevos registros para la diversidad marina de Cuba. Esta información podría contribuir a una mejor comprensión de los mecanismos que regulan a estos ecosistemas marinos y pudiera sentar las bases para el empleo de estas comunidades, como indicadores de condiciones ambientales en los arrecifes mesofóticos pues ya se utili- zan en arrecifes someros.Coral reefs are among the marine ecosystems most threatened by man and climate change. However, mesophotic reefs have been little studied, because the depths at which they are found add difficulties to their research. Although in recent years they have been of greater interest to science, due to the theory that depth protects them from regional and global stressors affecting “shallow” reefs. For this reason, a joint Cuba-United States expedition was carried out in 2017, with the aim of mapping and documenting the scope and health of mesophotic coral reefs along the entire coast ofCuba. During this journey, 3 sediment samples were extracted from 3 different mesophotic reefs in order to characterize the benthic foraminifera community. It was observed that foraminifera communities. Fourteen species from this group were identified as new records for Cuban marine diversity. This information could contribute to a better understanding of the mechanisms that regulate these marine ecosystems. It could also lay the foundations for the use of these communities as indicators of environmental conditions in mesophotic reefs, as they are already used in shallow reefs.
