“…Under this conceptual framework, a review by Cross et al (2015) proposes that rising temperature accelerates the metabolic rates regardless of nutrient availability because the first driver masks or counteracts the effect of the second one. This proposal is supported by recent findings reflecting a strong stimulatory warming effect on key processes such as primary (Lee and Kang, 2020;Schubert et al, 2019) and bacterial (Scofield et al, 2015) production or on microbial communities' β-diversity (Ren et al, 2017) regardless of nutrient status. Contrary to the proposal of Cross et al (2015), ocean-scale evidence supports the contention that nutrient availability controls the temperature dependence of metabolism and thus temperature may be far less decisive than expected under nutrient limitation (Marañón et al, 2014).…”

“…Many studies have found that high C:N (C:P) ratios generally occur more frequently at low DIN (PO 4 3− ) concentrations (Atkinson & Smith, 1983; Douglas et al, 2014; Fong et al, 1994; Gevaert et al, 2001; Lapointe et al, 2004; Lee & Kang, 2020; Menendez et al, 2002; Reef et al, 2012; Rico & Fernandez, 1996). The obvious explanation for the observed pattern is that lower DIN (or DIP) concentrations restrict the assimilation of these nutrients in seaweed biomass, which can be reflected in the occurrence of high C:N (C:P) ratios.…”

Algal carbon‐to‐nitrogen (C:N) and carbon‐to‐phosphorus (C:P) ratios are fundamental for understanding many oceanic biogeochemical processes, such as nutrient flux and climate regulation. We synthesized literature data (444 species, >400 locations) and collected original samples from Tasmania, Australia (51 species, 10 locations) to update the global ratios of seaweed carbon‐to‐nitrogen (C:N) and carbon‐to‐phosphorus (C:P). The updated global mean molar ratio for seaweed C:N is 20 (ranging from 6 to 123) and for C:P is 801 (ranging from 76 to 4102). The C:N and C:P ratios were significantly influenced by seawater inorganic nutrient concentrations and seasonality. Additionally, C:N ratios varied by phyla. Brown seaweeds (Ochrophyta, Phaeophyceae) had the highest mean C:N of 27.5 (range: 7.6–122.5), followed by green seaweeds (Chlorophyta) of 17.8 (6.2–54.3) and red seaweeds (Rhodophyta) of 14.8 (5.6–77.6). We used the updated C:N and C:P values to compare seaweed tissue stoichiometry with the most recently reported values for plankton community stoichiometry. Our results show that seaweeds have on average 2.8 and 4.0 times higher C:N and C:P than phytoplankton, indicating seaweeds can assimilate more carbon in their biomass for a given amount of nutrient resource. The stoichiometric comparison presented herein is central to the discourse on ocean afforestation (the deliberate replacement of phytoplankton with seaweeds to enhance the ocean biological carbon sink) by contributing to the understanding of the impact of nutrient reallocation from phytoplankton to seaweeds under large‐scale seaweed cultivation.

“…Es conocido que la cobertura de macroalgas es utilizada como indicador de deterioro general del ecosistema (Areces et al, 2015;Hughes, 1994;Littler & Littler, 1984), y en algunos casos, como indicador de enriquecimiento de nutrientes (Endo & Gao, 2022;Lee & Kang, 2020). Por lo que se considera que una alta cobertura de algas carnosas y calcáreas tiene un efecto negativo sobre el desarrollo de corales, ya que estos últimos incrementan su vulnerabilidad y disminuyen el asentamiento de reclutas (Hughes, 1994).…”

Introducción: Las comunidades de macroalgas marinas del Parque Nacional Guanahacabibes no han sido estudiadas desde el punto de vista cuantitativo, a pesar de la influencia que la vegetación submarina tiene sobre la estructura y el funcionamiento de los ecosistemas costeros, componente que hasta ahora ha sido subestimado en la región. Objetivo: Evaluar la variación temporal y espacial de los géneros de macroalgas en dos estaciones de María la Gorda, sur del Parque Nacional de Guanahacabibes, y evaluar la salud del arrecife de acuerdo con la cobertura de los diferentes morfo-tipos de macroalgas predominantes. Métodos: El estudio se realizó entre febrero de 2014 y marzo de 2017 en Laberinto y Yemayá con una frecuencia cuatrimestral, mediante buceo autónomo a una profundidad de 10 m. La cobertura algal fue estimada siguiendo la metodología AGRRA. Se calculó el porcentaje de cobertura que aporta cada género y de los grupos morfo-funcionales a la cobertura total encontrada en el área de estudio. Resultados: Los géneros dominantes durante el periodo de estudio fueron: Dictyota, Lobophora y Halimeda. Las algas carnosas y calcáreas mostraron mayor cubrimiento en Laberinto que en Yemayá, no siendo así con las formas costrosas. El índice de las carnosas fue superior en Laberinto. Conclusión: Se aporta una línea base para futuros estudios de monitoreo en Guanahacabibes y se sugiere que las evaluaciones ecológicas rápidas de macroalgas en el campo a nivel de género son un indicador confiable que se puede usar para monitorear cambios temporales.
