| dc.abstract.en | Mass mortality events (MMEs) are decimating populations and compromising key ecosystem functions around the globe. One taxon particularly vulnerable to MMEs is freshwater bivalve mollusks. This group has important ecosystem engineering capacities and includes highly threatened and highly invasive taxa. Thus, MMEs of freshwater bivalves have important implications for conservation and ecosystems. Despite this, little is known about the magnitude, frequency, duration, distribution, and causes of freshwater bivalve MMEs. Using a questionnaire, we compiled data from 239 reports describing freshwater bivalve MMEs across 22 European countries since 1960. With these data, we analyzed trends in MME timing, location, and magnitude; identified the species affected; and evaluated the suggested causes (including reporter certainty). We found that the frequency of reports of MMEs increased each year, MMEs affected a broad range of species, clear geographical patterns linking certain causes to specific locations were lacking, factors related to drying and habitat destruction predominated suggested causes, and considerable uncertainty surrounded the causes of many MMEs, particularly those associated with potential pollutants and disease agents. Based on our findings, we recommend the standardization of many aspects of MME research (e.g., reporting and recovery assessment protocols), increased surveying for MMEs, further investigation into the causes of MMEs, especially those with significant uncertainty, and immediate actions to improve waterbody management, mitigate the effects of high temperatures, and further protect freshwater bivalves through the development and implementation of appropriate management actions and legislation. | |

| dc.abstract.other | Distribución, escala y causantes de los eventos de mortalidad masiva de los bivalvos de agua dulce en Europa Resumen Los eventos de mortalidad masiva (EMM) diezman poblaciones y comprometen las funciones clave de los ecosistemas en todo el mundo. Un taxón particularmente vulnerable a los EMM es el de los moluscos bivalvos de agua dulce. Este grupo tiene capacidades importantes de ingeniería ecosistémica e incluye taxones altamente amenazados e invasivos. Por lo tanto, los EMM de los bivalvos de agua dulce tienen implicaciones importantes para la conservación y los ecosistemas. A pesar de ello, se sabe poco sobre la magnitud, la frecuencia, la duración, la distribución y las causas de estos EMM. Usamos un cuestionario para recopilar datos de 239 informes que describen los EMM de bivalvos de agua dulce en 22 países europeos desde 1960. Con estos datos, analizamos las tendencias en cuanto al momento, la ubicación y la magnitud de los EMM; identificamos las especies afectadas; y evaluamos las causas sugeridas (incluida la certeza de los informantes). Descubrimos que la frecuencia de los informes sobre EMM aumentaba cada año, que los EMM afectaban a una amplia gama de especies, que no existían patrones geográficos claros que relacionaran determinadas causas con lugares específicos, que los factores relacionados con la sequía y la destrucción del hábitat predominaban entre las causas sugeridas y que existía una considerable incertidumbre en torno a las causas de muchos EMM, en particular las asociadas a posibles contaminantes y agentes patógenos. Con base en nuestros hallazgos, recomendamos la estandarización de muchos aspectos de la investigación sobre EMM (por ejemplo, los protocolos de notificación y evaluación de la recuperación), el aumento de los estudios sobre EMM, una mayor investigación de las causas de los EMM, especialmente aquellos con un grado significativo de incertidumbre y la adopción de medidas inmediatas para mejorar la gestión de las masas de agua, mitigar los efectos de las altas temperaturas y proteger aún más los bivalvos de agua dulce mediante el desarrollo y la aplicación de medidas de gestión y legislación adecuadas. | |
