La acidificaci\u00f3n oce\u00e1nica (AO) se destaca como una de las principales amenazas para los ecosistemas marinos. La AO provoca una reducci\u00f3n en la disponibilidad de iones carbonato, esenciales para los organismos calcificadores marinos como los equinodermos. Nuestro objetivo es comprender las respuestas fisiol\u00f3gicas de dos especies de erizos de mar, Paracentrotus lividus y Arbacia lixula, a condiciones de bajo pH y determinar si dichas respuestas resultan de plasticidad fenot\u00edpica o de adaptaci\u00f3n local. El estudio se divide en dos partes: la respuesta pl\u00e1stica a lo largo del tiempo, midiendo las tasas de respiraci\u00f3n de individuos del mar Mediterr\u00e1neo expuestos a bajo pH durante siete d\u00edas, y la adaptaci\u00f3n y plasticidad bajo pH cambiante, analizando individuos que habitan un gradiente de pH en un sistema natural de emanaci\u00f3n de CO2 situado en la isla de La Palma, Espa\u00f1a. Durante los siete d\u00edas de exposici\u00f3n a bajo pH se revelaron patrones distintos en las tasas de respiraci\u00f3n, mostrando ambas especies potencial de aclimataci\u00f3n. Notablemente, P. lividus y A. lixula exhibieron ciclos de acidosis\/alcalosis no sincronizados, lo que sugiere mecanismos fisiol\u00f3gicos diferentes. Adem\u00e1s, la historia ambiental pareci\u00f3 influir en la capacidad adaptativa, ya que los ejemplares procedentes de ambientes con pH fluctuante mostraron tasas de respiraci\u00f3n similares a las de ambientes estables, con una mayor plasticidad fenot\u00edpica. En conjunto, nuestros resultados sugieren que ambas especies poseen capacidad de plasticidad metab\u00f3lica, lo que podr\u00eda aumentar su resiliencia frente a escenarios futuros de AO, aunque probablemente implique costes energ\u00e9ticos. Asimismo, los sistemas de emanaci\u00f3n de CO2 pueden actuar como refugios frente a la AO, facilitando la supervivencia a largo plazo. Comprender las respuestas pl\u00e1sticas frente a las adaptaciones es crucial para predecir los efectos de la AO sobre la distribuci\u00f3n y abundancia de los organismos marinos en respuesta al cambio clim\u00e1tico en curso.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/www.frontiersin.org\/journals\/marine-science\/articles\/10.3389\/fmars.2025.1500646\/full\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 hover_enabled=\u00bb0″ sticky_enabled=\u00bb0″][\/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

Ocean acidification (OA) stands out as one of the main threats to marine ecosystems. OA leads to a reduction in the availability of carbonate ions, which are essential for marine calcifiers such as echinoderms. We aim to understand the physiological responses of two sea urchin species, Paracentrotus lividus and Arbacia lixula to low pH conditions and determine whether their responses result from phenotypic plasticity or local adaptation. The study is divided into two parts: plasticity response over time, measuring respiration rates of individuals from the Mediterranean Sea exposed to low pH over seven days, and adaptation and plasticity under changing pH, analyzing individuals inhabiting a pH gradient in a natural CO2 vent system located in La Palma Island, Spain. Over the seven days of low pH exposure, distinct patterns in respiration rates were revealed, with both species demonstrating potential for acclimatization. Notably, P. lividus and A. lixula displayed unsynchronized acidosis\/alkalosis cycles, suggesting different physiological mechanisms. Additionally, environmental history seemed to influence adaptive capacity, as specimens from fluctuating pH environments exhibited respiration rates similar to those from stable environments with heightened phenotypic plasticity. Overall, our results suggest that both species possess the capacity for metabolic plasticity, which may enhance their resilience to future OA scenarios but likely involve energetic costs. Moreover, CO2 vent systems may serve as OA refugia, facilitating long-term survival. Understanding the plastic responses versus adaptations is crucial for predicting the effects of OA on species distribution and abundance of marine organisms in response to ongoing climate change.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
