Las erupciones volc\u00e1nicas submarinas son perturbaciones intensas y puntuales que pueden causar mortalidades bruscas y cambios duraderos en las comunidades marinas. En octubre de 2011, una erupci\u00f3n submarina frente a El Hierro (islas Canarias, Espa\u00f1a) gener\u00f3 una pluma sulfurosa que afect\u00f3 a la Reserva Marina Punta de La Restinga\u2013Mar de Las Calmas y a las zonas costeras cercanas. A partir de una serie temporal de 25 a\u00f1os de datos de comunidades de peces, evaluamos la evoluci\u00f3n de las especies comerciales tras la perturbaci\u00f3n en distintos niveles de protecci\u00f3n dentro de la zona afectada. La resiliencia se analiz\u00f3 como un proceso secuencial, dividido en resistencia (p\u00e9rdida inicial de biomasa), trayectoria de recuperaci\u00f3n (tendencia temporal tras la perturbaci\u00f3n) y recuperaci\u00f3n relativa respecto a las condiciones previas a la erupci\u00f3n. Como todos los sitios se vieron afectados por la pluma volc\u00e1nica, nuestras conclusiones se limitan a las diferencias entre categor\u00edas de protecci\u00f3n y no a la eficacia absoluta de la protecci\u00f3n. La zona de reserva integral mostr\u00f3 una resistencia relativa mayor y una recuperaci\u00f3n m\u00e1s r\u00e1pida de la biomasa total de peces que las zonas menos protegidas, lo que indica una din\u00e1mica m\u00e1s favorable tras la perturbaci\u00f3n. Sin embargo, ocho a\u00f1os despu\u00e9s de la erupci\u00f3n, la estructura de la comunidad no hab\u00eda vuelto del todo a las condiciones previas en ning\u00fan nivel de protecci\u00f3n, reflejo de los distintos tiempos de recuperaci\u00f3n de especies con historias de vida diferentes. Las especies de crecimiento r\u00e1pido, como la vieja Sparisoma cretense<\/em>, se recuperaron con rapidez, mientras que depredadores longevos como el mero Epinephelus marginatus<\/em> siguieron por debajo de su biomasa previa a la perturbaci\u00f3n. Nuestros resultados ofrecen una comparaci\u00f3n a largo plazo y a escala de comunidad de la recuperaci\u00f3n tras una erupci\u00f3n volc\u00e1nica dentro de una reserva marina, y muestran c\u00f3mo el nivel de protecci\u00f3n se asocia a diferencias en la din\u00e1mica de recuperaci\u00f3n ante una perturbaci\u00f3n natural poco frecuente.<\/p>\n[\/et_pb_text][et_pb_button button_url=\u00bbhttps:\/\/doi.org\/10.1371\/journal.pone.0346563″ 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

Submarine volcanic eruptions are strong pulse disturbances that can cause abrupt mortality and long-lasting changes in marine communities. In October 2011, a submarine eruption off El Hierro (Canary Islands, Spain) generated a sulphurous plume that affected the Punta de La Restinga\u2013Mar de Las Calmas Marine Reserve and surrounding coastal areas. Using a 25-year time series of fish community data, we assessed post-disturbance trajectories of commercial species across different protection levels within the impacted region. Resilience was analyzed as a sequential process, partitioned into resistance (initial biomass loss), recovery trajectory (temporal trend after the disturbance), and relative recovery compared with pre-eruption conditions. Because all sites were affected by the volcanic plume, our inference is restricted to comparative differences among protection categories rather than to the absolute effectiveness of protection. The no-take zone showed higher relative resistance and faster positive trajectories in total fish biomass than less-protected areas, indicating more favorable post-disturbance dynamics. However, eight years after the eruption, community structure had not fully returned to pre-eruption conditions in any protection level, reflecting contrasting recovery times among species with different life histories. Fast-growing species such as the parrotfish Sparisoma cretense<\/em> recovered rapidly, whereas long-lived predators such as Epinephelus marginatus<\/em> remained below their pre-disturbance biomass. Our results provide a long-term, community-level comparison of post-volcanic recovery within a marine reserve and highlight how protection status is associated with differences in recovery dynamics under a rare natural disturbance.<\/p>\n[\/et_pb_toggle][\/et_pb_column][\/et_pb_row][\/et_pb_section]\n","protected":false},"excerpt":{"rendered":"
