Los ecosistemas de agua dulce son una fuente primaria de servicios ecosistémicos esenciales para sustentar la vida y albergan una importante diversidad de especies acuáticas. El conocimiento sobre los macroinvertebrados acuáticos es precario en áreas declaradas como protegidas de Colombia. Este estudio tuvo como objetivo evaluar la diversidad de macroinvertebrados acuáticos bioindicadores y la calidad ecológica de hábitat del Parque Nacional Natural Selva de Florencia (PNNSF). Se recolectaron muestras de macroinvertebrados en seis microcuencas, cuatro ubicadas dentro del Parque y dos en la zona de amortiguamiento. Se realizaron análisis de diversidad de orden Q, variación en la composición de especies, y su relación con las variables fisicoquímicas. Para estimar la calidad del hábitat y del agua se aplicaron los siguientes índices: Índice de Integridad del Hábitat (IIH), Índice de Calidad del Ecosistema Ribereño (QBR), y el BMWP. Se recolectaron un total de 2894 macroinvertebrados acuáticos. Los órdenes más representativos fueron Ephemeroptera y Trichoptera. Los resultados del IIH fueron de moderada a alta integridad. El QBR fluctuó entre 65-100, indicando un nivel de calidad intermedia, buena y muy buena. El BMWP indicó que todos los afluentes estudiados se encuentran en la categoría de aguas muy limpias sin evidencias de contaminación. Finalmente, se concluye que el PNNSF y su zona de amortiguamiento están cumpliendo su función en la conservación de la diversidad acuática y se destaca la importancia de continuar con las estrategias de monitoreo implementadas en el PNNSF, a fin de asegurar el mantenimiento de su diversidad biológica e integridad ambiental.

Global aquaculture continues to grow, displacing capture fishing, a behavior that is reflected in Colombia through the cultivation of species such as red tilapia (Oreochromis sp.) and rainbow trout (Oncorhynchus mykiss), generating good quality protein for human consumption. However, production generates environmental impacts on water and lake ecosystems. This study determined water contamination in three rainbow trout farming companies in floating cages in the upper, middle and lower part of the RAMSAR Lago Guamuez wetland. Sampling was carried out in high and low rainfall, in six areas (three companies and three control points). Benthic macroinvertebrates were taxonomically identified, being used as bioindicators, calculating biological diversity indices such as Shannon diversity, Pielou evenness, Berger-Parker dominance and Margalef richness. In cultivation areas A, B and C, species tolerant to a certain degree of contamination such as Chironomidae, Thiaridae, Ampullariidae and Planaridae were found, while in control points A1, B1 and C1, species such as Libellulidae, hydrobiosidae and Hydrachnidae were found, which are less tolerant, indicating better water quality. The indices showed that there is an environmental impact caused by the productions, however, the presence-absence of species tolerant to a certain degree of pollution may be due to aquaculture productions and other anthropogenic activities such as tourism, wastewater, agricultural crops and oil spills. fuel of. Although it is true that the Lake is classified as oligotrophic, alarms must be raised to allow for its good management and preservation.

In this paper we review the 169 species or subspecies of arthropods previously considered endemic to the Sierra Nevada and update their status. To do so, we have reviewed all the existing literature on each taxon, from the original article in which it is described to any other article where its taxonomy and distribution is updated. We have also looked for information on possible endemic species or subspecies that may have been overlooked in the initial list, or that may have been described later. We considered four categories: 1) endemic, in the strict sense, those known only from the Sierra Nevada massif, 2) subendemic, occurring in one or two massifs or areas in addition to Sierra Nevada, 3) non-endemic, species that were considered endemic but live in three or more massifs or others areas, in addition to Sierra Nevada, and 4) not present, those that were erroneously cited as endemic to this massif but whose distribution does not include, either in the past or at present, Sierra Nevada. As a result, we have reviewed the status of 198 species and subspecies, of which 147 are endemic in the strict sense, 35 subendemic, 13 non-endemic and 3 not present. We also highlight the presence of 6 genera that are monospecific and exclusive to Sierra Nevada. Also, as a consequence of the extensive bibliographical revision, some of the dates of description or the names of some taxa have been modified. Finally, we highlight some species described from Sierra Nevada but which have not been found since their description, especially the case of the tettigonid Sabaterpia paulinoi (Bolívar, 1877) which we consider as possibly extinct.
