Esta tesis investiga los efectos de la acidificaci\u00f3n oce\u00e1nica en comunidades bent\u00f3nicas del Atl\u00e1ntico subtropical, utilizando el sistema de afloramientos de CO2 en La Palma, Islas Canarias, como laboratorio natural. El trabajo caracteriza qu\u00edmicamente el sistema de Punta de Fuencaliente, documentando un gradiente de pH (7.12-8.07) que replica condiciones futuras predichas. Mediante metabarcoding de ADN, se revelan altos niveles de diversidad taxon\u00f3mica en \u00e1reas acidificadas, sugiriendo que las comunidades futuras mantendr\u00e1n diversidad pero tender\u00e1n hacia la miniaturizaci\u00f3n con especies peque\u00f1as y cr\u00edpticas.
Adem\u00e1s, se valida la Hip\u00f3tesis de Perturbaciones Intermedias, mostrando que la diversidad gen\u00e9tica y taxon\u00f3mica alcanza m\u00e1ximos bajo fluctuaciones intermedias de pH. Finalmente, se identifican 432 SNPs bajo selecci\u00f3n en el erizo de mar Arbacia lixula, evidenciando adaptaci\u00f3n local al gradiente de acidificaci\u00f3n.
Esta investigaci\u00f3n demuestra la importancia de los laboratorios naturales para comprender las respuestas ecol\u00f3gicas y evolutivas a la acidificaci\u00f3n oce\u00e1nica.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/riull.ull.es\/xmlui\/bitstream\/handle\/915\/36103\/Tesis_Sara%20Gonz%C3%A1lez.pdf?sequence=1″ 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 thesis investigates ocean acidification effects on benthic communities in the subtropical Atlantic, using the CO2 vent system off La Palma, Canary Islands, as a natural laboratory. The work chemically characterizes the Punta de Fuencaliente system, documenting a pH gradient (7.12-8.07) that replicates predicted future conditions. Using DNA metabarcoding, high taxonomic diversity levels are revealed in acidified areas, suggesting future communities will maintain diversity but trend toward miniaturization with small, cryptic species.The research validates the Intermediate Disturbance Hypothesis, showing genetic and taxonomic diversity peaks under intermediate pH fluctuations. Finally, 432 SNPs under selection are identified in the sea urchin Arbacia lixula, evidencing local adaptation to the acidification gradient. This research demonstrates the importance of natural laboratories for understanding ecological and evolutionary responses to ocean acidification.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
