Nuestro estudio explora signos gen\u00f3micos de adaptaci\u00f3n en A. lixula<\/em> a diferentes condiciones de pH del agua. Para lograrlo, analizamos la variaci\u00f3n gen\u00f3mica de individuos de A. lixula<\/em> que habitan a lo largo de un gradiente natural de pH en las Islas Canarias, Espa\u00f1a. Utilizamos un protocolo 2b-RADseq con 74 muestras de sitios con diferentes niveles de pH (de 7,3 a 7,9 durante la marea baja), incluyendo un sitio de control. Identificamos 14.883 SNP, de los cuales 432 fueron detectados como candidatos a estar bajo selecci\u00f3n debido a variaciones en el pH mediante un an\u00e1lisis de redundancia. Aunque todos los SNP mostraron homogeneidad gen\u00f3mica, los 432 SNP candidatos bajo selecci\u00f3n revelaron diferencias gen\u00f3micas entre sitios y a lo largo del gradiente de pH. De estos 432 loci, 17 fueron anotados utilizando transcriptomas publicados de A. lixula<\/em> y est\u00e1n involucrados en funciones biol\u00f3gicas como el crecimiento. Por lo tanto, nuestros hallazgos sugieren una adaptaci\u00f3n local en las poblaciones de A. lixula<\/em> a la acidificaci\u00f3n en respiraderos de CO\u2082, incluso en distancias cortas de 75 m, lo que destaca su potencial resistencia a la futura acidificaci\u00f3n oce\u00e1nica.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/www.sciencedirect.com\/science\/article\/pii\/S0025326X24012025?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

Our study explores genomic signs of adaptation in A. lixula<\/em> to different water pH conditions. To achieve this, we analysed the genomics variation of A. lixula<\/em> individuals living across a natural pH gradient in Canary Islands, Spain. We use a 2b-RADseq protocol with 74 samples from sites with varying pH levels (from 7.3 to 7.9 during low tide) and included a control site. We identified 14,883 SNPs, with 432 identified as candidate SNPs under selection to pH variations through redundancy analysis. While all SNPs indicated genomic homogeneity, the 432 candidate SNPs under selection displayed genomic differences among sites and along the pH gradient. Out of these 432 loci, 17 were annotated using published A. lixula<\/em> transcriptomes, involved in biological functions such as growth. Therefore, our findings suggest local adaptation in A. lixula<\/em> populations to acidification in CO2<\/sub> vents, even over short distances of 75 m, underscoring their potential resistance to future Ocean Acidification.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
