 Este estudio examina los efectos a largo plazo de la AO sobre Arbacia lixula utilizando un sistema natural de emanaci\u00f3n volc\u00e1nica de CO2 en Fuencaliente, La Palma (Islas Canarias) como an\u00e1logo de las condiciones futuras. Analizamos la morfolog\u00eda externa, la resistencia del esqueleto, la mineralog\u00eda y el crecimiento de A. lixula en tres sitios que difer\u00edan consistentemente en pH medio (de 8,14 a 7,65 durante la bajamar). Los erizos procedentes de condiciones de bajo pH fueron m\u00e1s peque\u00f1os, con espinas m\u00e1s cortas y relaciones mand\u00edbula-di\u00e1metro reducidas, pero sus caparazones mostraron mayor resistencia a la fractura que los de condiciones ambientales. Adem\u00e1s, los individuos de zonas acidificadas presentaron din\u00e1micas de crecimiento alteradas, con menos anillos de crecimiento. Estos cambios esquel\u00e9ticos y las alteraciones en el crecimiento son coherentes con procesos de mineralizaci\u00f3n modificados y con cambios en la dieta hacia fuentes alimenticias no calc\u00e1reas. Este estudio pone de relieve la plasticidad morfol\u00f3gica y la resiliencia de A. lixula bajo acidificaci\u00f3n natural persistente, ofreciendo informaci\u00f3n sobre c\u00f3mo podr\u00edan responder los erizos de mar en un oc\u00e9ano con alto CO2.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/www.sciencedirect.com\/science\/article\/pii\/S0141113625005525?via%3Dihub\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 border_color_all=\u00bb#0C997F\u00bb]\n

This study examines the long-term effects of OA on Arbacia lixula using a natural volcanic CO2 vent at Fuencaliente, La Palma (Canary Islands) as an analogue of future conditions. We analyzed the external morphology, skeletal strength, mineralogy, and growth of A. lixula across three sites that differed consistently in mean pH (from 8.14 to 7.65 during low tide). Sea urchins from low pH conditions were smaller, with shorter spines and reduced jaw-to-diameter ratios, yet their tests showed higher fracture resistance than those from ambient conditions. Additionally, individuals from acidified zones showed altered growth dynamics, with fewer growth rings. Skeletal changes and growth alterations are consistent with modified mineralization processes and dietary shifts toward non-calcareous food sources. This study highlighting the morphological plasticity and resilience of A. lixula under persistent natural acidification, offering insight into how sea urchins may respond in a high-CO2 ocean.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
