“…Furthermore, Becherucci et al . (2016) mentioned that the seasonal differences of nutrient enrichment and epilithic animal competition can affect the algal succession pattern. Apparently, the low spore supply and the low seasonal recruitment rate significantly contributed to the decrease in NUF recovery rate, which also suggests that Ulva inhibition may depend on seasonal variables.…”

The inhibitory effects of ulvoid algae and their seasonality on the recovery and succession of an intertidal algal community were investigated under field conditions using a two‐factorial design. The experiment was conducted in the mid‐low intertidal zone on the Southern coast of Korea. In spring and fall, each of the ten 50 × 50 cm plots was disturbed artificially, and Ulva spp. were continuously excluded from five plots of the seasonal plots. The succession of spring plots was nearly twice as fast as that of the fall plots (spring, 4–6 months; fall, 10–15 months), indicating that the seasonal effects contributed significantly to the speed of the succession. The inhibition by Ulva species delayed the succession; however, the strength of this delay was limited largely by the duration and persistence of Ulva mass, which was also highly seasonal. The presence of Ulva spp. did not alter the final assemblage at the climax stage; instead, it caused a delay in community resilience. This study provides a few analytical factors for community‐wise comparison during the evaluation of the status of successional stages.

“…La sucesión de la comunidad bentónica también fue estudiada en relación a la descarga cloacal en Mar del Plata, mostrando períodos muy cortos de recuperación en sitios enriquecidos (contaminados). El poliqueto invasor Boccardia proboscidea fue dominante tanto en las etapas iniciales como en las etapas finales de la sucesión (Becherucci et al 2016;Llanos et al 2019).…”

Los poliquetos como indicadores biológicos en Latinoamérica y el Caribe

et al. 2020

Los poliquetos (Annelida) son organismos en íntimo contacto con el sedimento donde viven y el agua sobrenadante. El estrés ambiental genera rápidas respuestas en estos organismos que se reflejan en los individuos y sus poblaciones, por lo que se utilizan como indicadores biológicos de disturbios y de calidad ambiental. Los poliquetos han sido ampliamente utilizados en monitoreo ambiental y en bioensayos, y muchos estudios ecotoxicológicos se realizan con poliquetos. En casi todos los hábitats bentónicos estos organismos juegan un papel muy importante en la organización y estructura de las comunidades bentónicas y redes tróficas. Son un ítem fundamental en la alimentación de otros invertebrados y de aves migratorias y peces. Los poliquetos también tienen importancia económica para la industria farmacéutica, y de alimentos concentrados para especies marinas de cultivo (peces y crustáceos), en el campo médico y en la bioingeniería, además de la recreativa (acuarofilia, carnada) y por supuesto para el consumo humano. Varios de los índices de impacto ambiental y calidad ambiental existentes se basan en las características de tolerancia/sensibilidad de los organismos bentónicos, y muchos de ellos son poliquetos. Existen unos pocos trabajos de revisión de estos organismos como indicadores, pero todos en idioma inglés. Este trabajo muestra una actualización de los datos referidos a Latinoamérica y el Caribe, e incluye una amplia revisión bibliográfica.

“…This situation produced 15 km of beaches unfit for bathing because there was a risk for human health (Comino et al 2010). To date, multiple studies have been conducted in the study area to evaluate the effect of sewage effluent on benthic communities (Elías et al 2003(Elías et al , 2005(Elías et al , 2006(Elías et al , 2009Elias et al 2015;Elías 2006, Vallarino et al 2014;Jaubet et al 2011Jaubet et al , 2013Jaubet et al , 2015Garaffo et al 2012Garaffo et al , 2016Garaffo et al , 2017Sánchez et al 2013;Becherucci et al 2016). However, all these studies had an ecological approach based on taxonomic diversity.…”

Assessing functional diversity of macrobenthic assemblages in sewage-affected intertidal shores

et al. 2018

Functional diversity is the component of diversity that influences ecosystem dynamics, stability, productivity, nutrient balance, and other aspects of ecosystem functioning. We evaluate the spatio-temporal variability of the functional traits (biological traits analysis), functional diversity indices (functional richness, functional evenness, functional divergence and functional dispersion) and AZTI marine biotic index in response to the distinct levels of sewage contamination at different sites on intertidal abrasion platforms. Variations in macrobenthic functional structure between reference and impacted sites were evident in the study area. The functional richness showed a pattern with higher values in the reference sites; Functional evenness showed a similar pattern, but only during spring. Functional divergence presented lower values in the impacted sites during autumn and spring. The functional diversity indices (functional richness and functional evenness) and the AZTI marine biotic index presented a negative relationship, indicating that functional diversity is related to benthic environmental health. Thus, biological traits analysis and functional diversity indices, especially FRic that reveals differences in macrobenthic functional structure between impacted and reference sites during all seasons, represent an informative and useful tool to describe the different aspects of sewage impacts in benthic assemblages on rocky shores. These analyses have a high potential for future monitoring programmes.
