“…Regarding food sources, the gut content analysis showed that fine particulate organic matter (FPOM) is considered a resource of great importance for invertebrates in freshwater ecosystems, at least in running waters, due to its high abundance, availability and number of associated taxa, (Chará-Serna, Chará, Zúñiga, Pearson, & Boyero, 2012;Granados-Martínez, Zúñiga-Céspedes, & Acuña-Vargas, 2016;Tamaris-Turizo et al, 2018;Tomanova et al, 2006). However, in this study, it was not the most frequent resource, even in relation to other lentic systems, where organisms, are mostly shredders and filterers; and even quoted by Johnson, Goedkoop, and Sandin (2004) who found that the retention and processing of organic matter in the littoral zone of the lakes is high.…”

Introduction: The benthic fauna of the littoral zone in lakes is important in transferring energy to other trophic levels, habitat coupling, and helping to keep habitat stability. The study of this type of interactions in lentic systems is priority, since functional aspects about biological communities are unknown. Objective: Describing the trophic relations of aquatic invertebrates of the littoral zone in a tropical high mountain lake by characterizing gut content and stable isotope analysis of δ13C and δ15N. Methods: Samples of benthic invertebrates were collected in the littoral zone of the Lago de Tota where Egeria densa was present using a handheld net method. Samples were processed in the laboratory, organisms were identified, counted and weighed. Gut contents and δ13C and δ15N stable isotopes analysis were performed as well. Results: Records of the trophic relations of aquatic invertebrates, which live in the littoral in high mountain lentic ecosystem in the Neotropics are shown. The analysis of gut contents distinguished seven food items, microphytes and MOPF were the most frequent, and through the stable isotopes analysis (δ15N) we identified four trophic levels, among resources (macrophytes and POM), and consumers (detritivores, herbivores, and predators). The two upper trophic levels concentrated greater diversity and biomass. Conclusion: Most of the organisms studied were linked to omnivorous habits, evidenced in a wide spectrum of food items in their diet. The δ15N values show an enrichment, which occurs due to the effects of the tendency towards eutrophication of the system or due to unknown values of protozoa and bacteria that plays a fundamental role in the diet of these organisms, besides the δ13C values reported in organisms consumes, allows us to suggest an affinity with native resources of the littoral zone.

“…Chironomidae and Baetidae seem to be some of the preferred prey of the nymphs with predaceous habits (although many others have also been pointed out), generally those of mid to final instars, and in most of the studied species, as in some other Perloidea, a trophic shift from primary to secondary consumers has been pointed out (e.g. Lucy et al 1990;Dorvillé & Froehlich 2001;Tomanova et al 2006;Fenoglio et al 2007b;Bo et al 2008;Tierno de Figueroa et al 2015;Manko et al 2016;Hurtado-Borrero et al 2018;Tamaris-Turizo et al 2018). Chloroperlidae, which are phylogenetically related to Perlodidae and Perlidae, are considered omnivorous (Zwick 1980).…”

We here review the current knowledge on the trophic ecology of stoneflies, an aquatic insect group of substantial ecological importance in lotic systems. We provide information on the feeding habits of nymphs and adults of the different families and highlight those studies that support particularly interesting findings. Regarding nymphs, we discuss the state of the art on aspects such as foraging strategies and behaviours, food acquisition mechanisms, the existence or absence of electivity for certain trophic resources, and enzymatic activity and its relationship with the assimilation efficiency of food. For adults, we highlight the differential importance of feeding among taxa. For both nymphs and adults, we report what is known about their role in aquatic and terrestrial food webs. Finally, we present some of the gaps on the trophic ecology of these insects and provide some research agendas that could be carried out to fill them.

“…Sin embargo, la información detallada de las respuestas y los rangos de tolerancia de la comunidad de macroinvertebrados a la estacionalidad de las variables hidráulicas en escalas espaciales finas es escasa (Ríos-Touma, et al, 2011;Cardona, 2012;Vimos, et al, 2019). Además, muy pocos de estos estudios han abordado el comportamiento de los GFA de la comunidad en relación con las variables hidráulicas (Jacobsen & Encalada, 1998;Tomanova, et al, 2006;Ramírez & Gutiérrez-Fonseca, 2014;Tamaris-Turizo, et al, 2018).…”

En este estudio se evaluó la respuesta de la composición, la estructura y la función de la comunidad de macroinvertebrados a la variación temporal hidráulica en el río Agua Blanca. Se recolectaron 60 muestras en dos tramos durante dos épocas hidroclimáticas mediante un muestreo aleatorio estratificado. Se midió el caudal y el ancho del canal, así como la velocidad, la profundidad y elnúmero de Froude (Fr) en cada muestra biológica. En la prueba de Kolmogorov-Smirnov se evidenció un incremento significativo en los valores de la velocidad, el caudal y el Fr durante la época de lluvias. El análisis ANOSIM evidenció una variación temporal en la composición y la estructura de la comunidad. Los géneros Leptohyphes, Smicridea, Helicopsyche, Nanomis y Marilia fueron más abundantes en la época de transición, y las familias Simuliidae y Sericostomatidae en la época de lluvias. El grupo funcional alimentario (GFA) dominante en la época de transición fue el de colectores-recolectores (CR) y en la de lluvias, el de los fragmentadores (FR) y colectores-filtradores (CF). Según el análisis de correspondencia canónica (ACC), Simuliidae y Metrichia se asociaron con valores altos de la profundidad, Mayobaetis con el ancho del cauce y Sericostomatidae con la velocidad y el Fr. Los ostrácodos, Meridialis y Triplectides presentaron una asociación negativa con la velocidad. Según las curvas de preferencia, el rango óptimo de velocidad para la familia Sericostomatidae fluctuó entre 1,8 m.s-1 y 2,3 m.s-1, en tanto que las profundidades óptimas para la familia Simuliidae estuvieron entre 0,3 m y 0,55 m. Se resalta el papel de las variables hidráulicas evaluadas como determinantes de la presencia de algunos géneros y grupos funcionales.
