“…benoisti and P. nigrofacialis were the only Calliphoridae species found exclusively in the forest environment. The genus Paralucilia is common in preserved environments [23,24]. In this study, P. nigrofacialis showed the lowest level of synanthropy, being exclusive to the forest environment, according to the literature cited above.…”

The determination of the synanthropic index is essential to evaluate the degree of association between species, such as diptera and man, based solely on their degree of preference for urban areas. This research aimed to study the synanthropic behavior of Calliphoridae and Mesembrinellidae flies in Rio de Janeiro, Brazil. The experiment was conducted between 2021 and 2022 in three areas, where four traps containing 300 g of fresh liver or with 48 h of putrefaction were installed, remaining exposed for 48 h; after collection the dipterans were sacrificed and taxonomically identified. A total of 2,826 dipterans were collected, represented by nine species of Calliphoridae (89.24%) and ten of Mesembrinellidae (10.76%), with the first record of Mesembrinella currani in this biome. The Kruskal-Wallis test showed that the abundance of individuals did not differ among the three analyzed environments. The Mesembrinellidae family was exclusively asynanthrope, along with two species of Calliphoridae: Hemilucilia benoisti (Séguy 1925) and Paralucilia nigrofacialis (Mello 1969) which were exclusive of the forest area, while Calliphoridae had varied synanthropy. Lucilia eximia (Wiedemann 1819) alone represented 57.18% of the total sampled, being the most abundant in all environments except the urban area where Hemilucilia segmentaria (Fabricius 1805) totaled 55.73%. No species were exclusive to the urban area, however Cochliomyia hominivorax (Coquerel 1858) and Lucilia cuprina (Wiedemann 1830) were exclusive to the rural area. The most synanthropic species were Chrysomya megacephala (Fabricius 1794) and Chrysomya albiceps (Wiedemann 1819).

“…In this study, Diptera larvae and pupae were the second most important category in the diet of M. collettii , with an emphasis on the Chironomidae family. This family is known for its tolerance to environmental degradation and is common in the diet of fishes in anthropized streams (Mendes et al, 2021; Peressin et al, 2018). The availability of animals in the aforementioned category is also related to three factors: ecological diversity, occurrence in different habitats, and a critical position in food chains (e.g., secondary production and energy flow).…”

The present study aimed to characterize the diet of Moenkhausia collettii and investigate possible changes due to environmental variations and its body size in streams in the eastern Amazon. The specimens were sampled monthly between April 2019 and March 2020. They were measured for standard length (SL) and total mass (Tm) and eviscerated for analysis of stomach contents. Food items were identified and grouped into categories. Dietary aspects such as food importance index (AI%), trophic niche width, and stomach repletion index (SRI%) were evaluated. Furthermore, generalized linear models (GLMs) were used to evaluate the relation between diet and the SL, as well as between diet and the environmental variables of streams. A total of 355 specimens with SL ranging from 11.06 to 46.03 mm and weight ranging from 0.020 to 2.373 g were evaluated. Out of the 355 stomachs analysed, 88 contained material in an advanced stage of decomposition and 12 were empty. The diet of M. collettii was considered omnivorous, with a tendency toward insectivory. Formicidae was the most important category in the diet of the species, followed by immature Diptera and plant material. The GLMs showed a relationship between the diet and a set of environmental variables such as dissolved oxygen, conductivity, flow, width, depth, wood, leaf bank, and SL. The trophic niche width and feeding intensity increased with the length of the species, as well as in the period of higher precipitation, reinforcing trophic opportunism for M. collettii. Therefore, new studies that combine the traditional method of stomach content analysis, the use of stable isotopes, as well as ecomorphological attributes, are crucial for a profound understanding of the trophic ecology of the ichthyofauna in the face of natural changes occurring in their environment.
