“…It therefore can be assumed that the fish hosts involved, as well as their parasites, have a high tolerance to geogenic background concentrations if the host-parasite systems could evolve adaptation measures. Similarly, higher abundance and prevalence of acanthocephalans was found at sites with poorer ecological status according to biological indices and bacterial loads when comparing different river sections [85].…”

“…Accordingly, acanthocephalans might be directly affected by pollutants or indirectly via impacts on the host [28]. A correlation between the occurrence of acanthocephalan parasites and the abundance of intermediate hosts unraveled by Fanton et al (2022) [49], is in contrast to a study that reported no significant effects of environmental stressors, such as pollution on acanthocephalans [19]. Such contradictory findings suggest a lack of thorough understanding of the effects of environmental stressors on the development and transmission of acanthocephalans.…”

“…Similarly, acanthocephalans might be adversely affected by metals [93]. Other studies reported a higher abundance of acanthocephalans at sites with higher organic/nutrient loads and eutrophication levels, respectively (see e.g., [49,175], which was assumed to be linked to a higher pollution tolerance of intermediate and definitive hosts. Accordingly, acanthocephalans might be directly affected by pollutants or indirectly via impacts on the host [28].…”

Although interest in Acanthocephala seems to have reached only a small community of researchers worldwide, we show in this opinion article that this group of parasites is composed of excellent model organisms for studying key questions in parasite molecular biology and cytogenetics, evolutionary ecology, and ecotoxicology. Their shared ancestry with free-living rotifers makes them an ideal group to explore the origins of the parasitic lifestyle and evolutionary drivers of host shifts and environmental transitions. They also provide useful features in the quest to decipher the proximate mechanisms of parasite-induced phenotypic alterations and better understand the evolution of behavioral manipulation. From an applied perspective, acanthocephalans’ ability to accumulate contaminants offers useful opportunities to monitor the impacts – and evaluate the possible mitigation – of anthropogenic pollutants on aquatic fauna and develop the environmental parasitology framework. However, exploring these exciting research avenues will require connecting fragmentary knowledge by enlarging the taxonomic coverage of molecular and phenotypic data. In this opinion paper, we highlight the needs and opportunities of research on Acanthocephala in three main directions: (i) integrative taxonomy (including non-molecular tools) and phylogeny-based comparative analysis; (ii) ecology and evolution of life cycles, transmission strategies and host ranges; and (iii) environmental issues related to global changes, including ecotoxicology. In each section, the most promising ideas and developments are presented based on selected case studies, with the goal that the present and future generations of parasitologists further explore and increase knowledge of Acanthocephala.

“…Por el contrario, el metanálisis de Blanar et al (2009) establece que los efectos de la contaminación (pesticidas, hidrocarburos aromáticos policíclicos, bifenilos policlorados y metales pesados) en los acantocéfalos no fueron significativos. De hecho, algunas poblaciones de acantocéfalos pueden disminuir ante una perturbación, mientras que otras pueden aprovecharla (Fanton et al, 2022). Estos no solo estarían afectados por los impactos directos de la contaminación, sino que también por el riesgo combinado de estos cambios ambientales sobre sus anfitriones (Carlson et al, 2017).…”

El objetivo general de la presente tesis fue estudiar el grado en el cual las comunidades parasitarias de peces en ambientes dulceacuícolas pampeanos con distinto grado de impacto antrópico pueden utilizarse como indicadores de alteraciones del medio ambiente y la biodiversidad. Al examinar la fauna parasitaria de los hospedadores como posibles indicadores de alteraciones ambientales, se observó una notable diversidad en P. rutilus en los arroyos con menos disturbios asociados a sus cuencas. Este hallazgo sugiere la existencia de una amplia diversidad en los ambientes estudiados. Dado su papel como depredador generalista y la sugerencia de varios estudios para utilizarlo en investigaciones sobre impacto antrópico, podríamos proponer a este hospedador para posibles monitoreos dentro de cada entorno, utilizando su fauna parasitaria como indicador de cambios ambientales. En cambio, C. decemmaculatus y C. interruptus presentan un panorama diferente, ya que no se encontró un patrón marcado entre los sitios disturbados. Los parásitos podrían indicar que el ambiente no está muy disturbado o que la alteración ambiental presente no es letal para estos parásitos y sus hospedadores intermediarios y definitivos. Este trabajo sienta las bases para posibles monitoreos dentro de cada ambiente utilizando la fauna parasitaria como indicadora de cambios ambientales. La comprensión de los ciclos de vida, la toma de muestras de agua y sedimentos con la recolección de peces, así como el desarrollo de ensayos en laboratorio con diferentes contaminantes, permitirán inferir con mayor detalle el efecto de estos factores sobre la fauna parasitaria.
