Se estudi\u00f3 la producci\u00f3n primaria y las tasas de respiraci\u00f3n de seis especies de algas (<\/span>Cystoseira abies-marina, Lobophora variegata, Pterocladiella capillacea, Canistrocarpus cervicornis, Padina pavonica<\/span><\/i> y <\/span>Corallina caespitosa<\/span><\/i>) del Atl\u00e1ntico nororiental subtropical, para estimar los efectos combinados de diferentes niveles de pH y temperatura. Se cultivaron muestras de macroalgas a combinaciones de temperatura y pH que iban desde los niveles actuales hasta los previstos para el pr\u00f3ximo siglo (19, 21, 23, 25 \u00b0C, pH: 8,1, 7,7 y 7,4). La disminuci\u00f3n del pH tuvo un efecto positivo en la producci\u00f3n a corto plazo de las especies estudiadas. El aumento de las temperaturas tuvo un efecto m\u00e1s variado y dependiente de la especie, sobre la producci\u00f3n primaria a corto plazo. Las algas term\u00f3filas aumentaron su producci\u00f3n a temperaturas m\u00e1s altas, mientras que las especies templadas fueron m\u00e1s productivas en condiciones de temperatura m\u00e1s bajas o presentes. La temperatura tambi\u00e9n afect\u00f3 a las tasas de respiraci\u00f3n de las algas, que fueron mayores a niveles de temperatura bajos. Los resultados sugieren que la biomasa y la productividad de las especies m\u00e1s tropicales de los ecosistemas costeros se ver\u00edan favorecidas por las futuras condiciones oce\u00e1nicas.<\/span><\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/wp.ull.es\/omacc\/wp-content\/uploads\/sites\/110\/2022\/04\/Herna\u0301ndez-et-al.-2018.MERE_.pdf\u00bb url_new_window=\u00bbon\u00bb button_text=\u00bbDescargar pdf\u00bb _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb custom_button=\u00bbon\u00bb button_text_size=\u00bb13px\u00bb button_bg_color=\u00bb#0C997F\u00bb][\/et_pb_button][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\u00bb2_5,3_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][et_pb_column type=\u00bb2_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][\/et_pb_column][et_pb_column type=\u00bb3_5″ _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb][et_pb_toggle title=\u00bbEnglish\u00bb open_toggle_text_color=\u00bb#0C997F\u00bb open_toggle_background_color=\u00bb#FFFFFF\u00bb closed_toggle_text_color=\u00bb#0C997F\u00bb closed_toggle_background_color=\u00bb#FFFFFF\u00bb icon_color=\u00bb#0C997F\u00bb _builder_version=\u00bb4.9.7″ _module_preset=\u00bbdefault\u00bb title_font=\u00bb|||on|||||\u00bb closed_title_font=\u00bb|||on|||||\u00bb closed_title_font_size=\u00bb14px\u00bb closed_title_line_height=\u00bb1.5em\u00bb custom_padding=\u00bb7px||7px||true|false\u00bb hover_enabled=\u00bb0″ border_color_all=\u00bb#0C997F\u00bb sticky_enabled=\u00bb0″]\n

Primary production and respiration rates were studied for six seaweed species (<\/span>Cystoseira abies-marina, Lobophora variegata, Pterocladiella capillacea, Canistrocarpus cervicornis, Padina pavonica<\/span><\/i> and <\/span>Corallina caespitosa<\/span><\/i>) from Subtropical North-East Atlantic, to estimate the combined effects of different pH and temperature levels. Macroalgal samples were cultured at temperature and pH combinations ranging from current levels to those predicted for the next century (19, 21, 23, 25 \u00b0C, pH: 8.1, 7.7 and 7.4). Decreased pH had a positive effect on short-term production of the studied species. Raised temperatures had a more varied and species dependent effect on short term primary production. Thermophilic algae increased their production at higher temperatures, while temperate species were more productive at lower or present temperature conditions. Temperature also affected algal respiration rates, which were higher at low temperature levels. The results suggest that biomass and productivity of the more tropical species in coastal ecosystems would be enhanced by future ocean conditions.<\/span><\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
