“…For example, it has been shown that crane flies (shredder, Diptera: Tipulidae) require microbial conditioning of leaf surfaces for development and use gut bacteria to help break down ingested food (Klug & Kotarski 1980;Lawson & Klug 1989). While in terrestrial systems, the functional roles of microbes are widely documented (e.g., nitrogen fixation or cellulose degradation) (Alonso- Pernas et al, 2017;Alonso-Pernas et al, 2018;Ayayee et al, 2018;Gupta et al, 2012), in aquatic systems comparatively little research exists, but it is hypothesized that there are similar relationships (Ayayee et al, 2018). Although we chose not to examine individual functional pathways due to limitations of using gene amplicon data for this purpose in understudied systems (Langille 2018;Langille et al, 2013;Radivojac et al, 2013), we found that the internal bacterial functional diversity was distinctly different between species, with species explaining close to half (41%) of the variation present.…”

The roles of macroinvertebrate and microbial communities in stream ecosystems are recognized to be important to energy flow and nutrient cycling. While the linkages of these major groups of aquatic organisms has not been thoroughly investigated, determining how they interact is particularly important for understanding the mechanisms and potential evolutionary relationships that contribute to ecosystem processes, such as organic matter decomposition. We evaluated the microbiomes of several aquatic macroinvertebrate species differing in trophic ecology and belonging to different functional feeding groups at two sites along an Italian Alpine river with different elevation and environmental characteristics, one located above the tree-line and the other in a forested environment. We found that the internal microbial communities of the different insect species significantly varied in taxonomic and functional composition and could be used to classify samples to both species and environment. We demonstrated that functional differences existed between the microbiota of different macroinvertebrate species with variable feeding behaviors, and that species differences were more important, in this context, than environmental or habitat conditions. These results provide new information on how the microbiomes of macroinvertebrates may potentially be influenced by their hosts and habitat conditions in Alpine streams.

“…After that, using isotope mass spectrometer to detect the content of N 14 and N 15 in samples within a certain time and calculate the values of δ 15 N, which reflects the efficiency of nitrogen fixation [47]. Similarly, N 15 -labeled nitrogenous waste compounds, such as uric acid [48] and urea [30,49], are usually added to the diets when evaluating the efficiency of NWR, the values of δ 15 N in samples are calculated after feeding a period of time.…”

“…Among them, the highest uric acid content is detected in female adults, whose guts contain various uricolytic bacteria, such as Pseudomonas fluorescens, Serratia proteamaculans, and Rahnella aquatilis [65]. Urea-hydrolyzing bacteria present in the egg surface and larval guts of Anoplophora glabripennis or the larval and adult guts of Melolontha hippocastani can incorporate nitrogen from ingested urea back into the insect tissues [30,49].…”

Nitrogen is usually a restrictive nutrient that affects the growth and development of insects, especially of those living in low nitrogen nutrient niches. In response to the low nitrogen stress, insects have gradually developed symbiont-based stress response strategies—biological nitrogen fixation and nitrogenous waste recycling—to optimize dietary nitrogen intake. Based on the above two patterns, atmospheric nitrogen or nitrogenous waste (e.g., uric acid, urea) is converted into ammonia, which in turn is incorporated into the organism via the glutamine synthetase and glutamate synthase pathways. This review summarized the reaction mechanisms, conventional research methods and the various applications of biological nitrogen fixation and nitrogenous waste recycling strategies. Further, we compared the bio-reaction characteristics and conditions of two strategies, then proposed a model for nitrogen provisioning based on different strategies.
