    Beschreibung: The response of the marine carbon cycle to changes in atmospheric CO2 concentrations will be determined, in part, by the relative response of calcifying and non-calcifying organisms to global change. Planktonic foraminifera are responsible for a quarter or more of global carbonate production, therefore understanding the sensitivity of calcification in these organisms to environmental change is critical. Despite this, there remains little consensus as to whether, or to what extent, chemical and physical factors affect foraminiferal calcification. To address this, we directly test the effect of multiple controls on calcification in culture experiments and core-top measurements of Globigerinoides ruber. We find that two factors, body size and the carbonate system, strongly influence calcification intensity in life, but that exposure to corrosive bottom waters can overprint this signal post mortem. Using a simple model for the addition of calcite through ontogeny, we show that variable body size between and within datasets could complicate studies that examine environmental controls on foraminiferal shell weight. In addition, we suggest that size could ultimately play a role in determining whether calcification will increase or decrease with acidification. Our models highlight that knowledge of the specific morphological and physiological mechanisms driving ontogenetic change in calcification in different species will be critical in predicting the response of foraminiferal calcification to future change in atmospheric pCO2.

    Beschreibung: La Siguanea inlet, one of the two inlets present in the Gulf of Batabanó, contains essential habitats such as seagrass beds and mangroves. However, it has been poorly studied and currently there is little information about the biological diversity in the area. The aim of this study was to make the first check list of fishes on this region of the Cuban archipelago. We used complementary methodologies such as multiple seine nets, gill net, drum lines, visual census and underwater video census. The inventory recorded 122 species of fishes distributed in 53 families. The best represented families were Haemulidae, Lutjanidae, Scaridae, Carangidae, Monacanthidae and Gerreidae. This finding coincided partially with similar studies done in other Cuban shelf areas, although the order of these may vary. During the surveys a high proportion of juvenile fishes was found, which suggests a possible nursery site that could be playing an important role in fish stocks in the area. This result contributes to raise the knowledge about marine biodiversity in Cuba and also for the Caribbean, providing a baseline of fish for the area. In this work we found a high diversity of fishes in La Siguanea inlet, as well as a high proportion of juveniles. Future studies that explore the composition and structure of fish stocks in the area are required; as well as studies on the possible connectivity between this area and the reefs in Punta Francés. Allowing a better understanding of ecological processes in the area, and in turn a better use and management of these natural resources.
    Beschreibung: La Ensenada de la Siguanea es una de las dos ensenadas presentes en el Golfo de Batabanó, en la cual se pueden encontrar importantes hábitats para el desarrollo de los peces como son los pastizales y los manglares. No obstante, esta ensenada ha sido poco estudiada y se cuenta con poca información sobre la diversidad biológica en el área. El objetivo de este estudio fue realizar, por primera vez para el área, un inventario de las especies de peces. Se emplearon diferentes metodologías de muestreo como redes de pesca, palangres, censos visuales y videos bajoel agua. Se inventariaron 122 especies de peces distribuidas en 53 familias. Las familias más diversas fueron Haemulidae, Lutjanidae, Scaridae, Carangidae, Monacanthidae y Gerreidae, coincidiendo parcialmente con resultados previos en otras regiones del país, aunque su orden puede variar. En los muestreos se encontró una alta proporción de juveniles de peces, sugiriendo que esta es una zona de crianza, que puede tener un rol importante en las poblaciones de peces en el área. Estos resultados contribuyen al conocimiento de la diversidad marina en Cuba y el Caribe, proporcionado una línea base de la ictiofauna para la Ensenada de la Siguanea. En este trabajo se encontró una alta diversidad de de peces en la Siguanea, así como un elevada proporción de juveniles. Se requieren de estudios futuros que exploren la composición y estructura de las poblaciones de peces en el área, así como la posible conectividad entre esta área y el Parque Nacional Punta Francés. Esto permitirá un mejor entendimiento de los procesos ecológicos en el área, y un mejor uso y manejo de los recursos naturales.
