description Coralline algae form abundant and ecologically important submerged aquatic vegetation habitats throughout the world. However, algal performance is threatened by climate change and ocean acidification. Previous studies suggest that their photosynthetic performance will be compromised mainly at elevated temperatures. Understanding the impact of diverse climate change scenarios requires a clear and thorough comprehension of the photosynthetic response to temperature gradients. The objective of this study was to evaluate the short-term effect of temperature (10–35 °C) on the gross photosynthesis (GPS), respiration, and electron transport rates (ETRs) of 3 articulated coralline algae (Lithothrix aspergillum, Corallina officinalis, and Bossiella orbigniana) for a better understanding of their metabolism and to investigate the relationship between GPS and ETR as a function of temperature. The results showed that the coralline algal metabolism is highly sensitive to temperature, but responses were species-specific and can be related to their light adaptation/acclimation; the high-light-adapted L. aspergillum was least negatively affected. The photosynthesis to respiration ratio was optimal between 20 and 25 °C according to the local thermal regime but was significantly reduced toward higher temperatures, indicating strong carbon imbalances and highlighting the relevance of thermal stress for coralline algal performance. A strong correlation between GPS and ETR was found between 10 and 30 °C in all species, but both above saturation irradiances and at elevated temperatures (≥30 °C), a clear deviation from linearity occurred. This suggests that ETR is not a good proxy to estimate photosynthetic activity under light or thermal stress. This information should be useful for studies implementing global change scenarios and pulse amplitude modulated (PAM) fluorometry in coralline algae.

El desempeño algal, no obstante, está amenazado por el cambio climático y la acidificación del océano. Estudios previos han sugerido que su desempeño fotosintético estará comprometido, principalmente a elevadas temperaturas. El entendimiento del impacto de diversos escenarios del cambio climático requiere comprensión exhaustiva de la respuesta fotosintética a los gradientes de temperatura. Este estudio evaluó el efecto a corto plazo de la temperatura (10–35 °C) en la fotosíntesis bruta (FSB), la respiración y la tasa del transporte de electrones (TTE) de 3 especies de algas coralinas articuladas (Lithothrix aspergillum, Corallina officinalis y Bossiella orbigniana) para entender mejor su metabolismo e investigar la relación entre la FSB y la TTE en función de la temperatura. Los resultados mostraron que el metabolismo coralino es altamente sensible a la temperatura, pero las respuestas fueron específicas para cada especie y pueden estar relacionadas con su aclimatación/adaptación lumínica; L. aspergillum, alga adaptada a alta luz, fue la menos afectada negativamente. La razón fotosíntesis: respiración fue óptima a 20–25 °C, según el régimen térmico local, pero se redujo significativamente a temperaturas altas; esto indica fuertes desbalances de carbono y resalta la relevancia del estrés térmico para el desempeño fotosintético coralino. Se encontró una fuerte correlación entre la FSB y la TTE entre los 10 y 30 °C para todas las especies, pero se observó una clara desviación de esta linealidad por encima de las irradiancias de saturación y a temperaturas elevadas (≥30 °C). Lo anterior sugiere que la TTE no es un buen indicador de la actividad fotosintética bajo condiciones de estrés lumínico o térmico. Esta información debería ser útil para estudios que implementen escenarios de cambio global y fluorometría de pulso de amplitud modulada (PAM) en algas coralinas.Iniversidad Autónoma de Baja California2022-10-28info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionPeer-reviewed Article Artículo Arbitradoapplication/pdftext/xmltext/xmlhttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/326910.7773/cm.y2022.3269Ciencias Marinas; Vol. 48 (2022)Ciencias Marinas; Vol. 48 (2022)2395-90530185-3880reponame:Ciencias Marinasinstname:UNIVERSIDAD AUTÓNOMA DE BAJA CALIFORNIAinstacron:UABCengspahttps://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3269/420420697https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3269/420420922https://www.cienciasmarinas.com.mx/index.php/cmarinas/article/view/3269/420420923Copyright (c) 2022 Román Manuel Vásquez-Elizondo, Wiebke E Kräemer, Alejandro Cabello-Pasinihttps://creativecommons.org/licenses/by/4.0info:eu-repo/semantics/openAccessoai:cienciasmarinas.com.mx:article/32692024-08-22T17:01:42Z
