“…Adult yellow perch could contribute to the higher trophic position, based on their ecology and stable isotope signature in Lake 1. Benthic macroinvertebrates, like larval insects, could contribute to the more nearshore signal in the winter in Lake 1 because they mainly occupy the littoral zone (Koroiva and Pepinelli, 2019). However, they can also be found in profundal benthic habitat (e.g., some Diptera larvae), and we did not extensively characterize the stable isotope ecology of larval insects in our study lakes.…”

Seasonality could play a crucial role in structuring species interactions. For example, many ectotherms alter their activity, habitat, and diet in response to seasonal temperature variation. Species also vary widely in physiological traits, like thermal preference, which may mediate their response to seasonal variation. How behavioral responses to seasonality differ between competing species and alter their overlap along multiple niche axes in space and time, remains understudied. Here, we used bulk carbon and nitrogen stable isotopes combined with stomach content analysis to determine the seasonal diet overlap between a native cold-water species [lake trout (Salvelinus namaycush)] and a range-expanding warm-water species [smallmouth bass (Micropterus dolomieu)] in two north-temperate lakes over 2 years. We coupled these analyses with fine-scale acoustic telemetry from one of the lakes to determine seasonal overlap in habitat use and activity levels. We found that dietary niche overlap was higher in the spring, when both species were active and using more littoral resources, compared to the summer, when the cold-water lake trout increased their reliance on pelagic resources. Telemetry data revealed that activity rates diverged in the winter, when lake trout remained active, but the warm-water smallmouth bass reduced their activity. Combining stable isotopes and stomach contents with acoustic telemetry was a powerful approach for demonstrating that species interactions are temporally and spatially dynamic. In our case, the study species diverged in their diet, habitat, and activity more strongly during certain times of the year than others, in ways that were consistent with their thermal preferences. Despite large differences in thermal preference, however, there were times of year when both species were active and sharing a common habitat and prey source (i.e., resource overlap was greater in spring than summer). Based on our findings, important ecological processes are occurring during all seasons, which would be missed by summer sampling alone. Our study stresses that quantifying multiple niche axes in both space and time is important for understanding the possible outcomes of altered seasonal conditions, including shorter winters, already arising under a changing climate.

“…Terrestrial waters account for only 1% of the earth's total surface area. Nevertheless, they are highly diverse in terms of their salinity, temperature, dissolved oxygen (DO) content, bottom sediment texture and composition, and geographical features (Koroiva & Pepinelli, 2019). Fluidity also greatly influences aquatic insect adaptation.…”

Background: Water flow is one of several factors that determine the habitats of aquatic insects. The conversions of stagnant (lentic) and running (lotic) water are physiologically and ecologically constrained. In general, aquatic insect species only occur in one of these environments. Though Eubrianax ramicornis (Coleoptera: Psephenidae) usually resides in rivers, however, it is also known to occur near the shores of Lake Biwa in Japan. Here, we investigated the genetic differences between the two Eubrianax species of Lake Biwa and its inflowing rivers, and other regions of Japan for the first time. Lake Biwa is an ancient lake and about four million years old. Though over 60 endemic species were described from Lake Biwa, they are mostly fish and molluscs, with only two species of aquatic insects. There are few reports of endemic aquatic insects in other ancient lakes, too. Discussion of the endemism of Eubrianax and its promoting factors is expected to provide insights into the evolution of aquatic insects in ancient lakes. Methods: We surveyed and morphologically identified psephenid larvae in Lake Biwa and its inflowing rivers during the summers of 2017 and 2018 (Hayashi, 2009: Hayashi & Sota, 2009). We conducted phylogenetic analyses of two regions of COI and estimated the ages of population divergence based on fossil records of Eubrianax beetles in Lake Biwa as well as those of previously reported populations in other regions. We also analyzed two COI regions of the E. ramicornis haplotypes in Lake Biwa. Results: Four psephenid species were identified among the samples collected in Lake Biwa and its inflowing rivers. Of these, E. ramicornis was collected only at the Lake Biwa shore whereas its congeneric E. granicollis was collected only from the rivers inflowing the lake. The phylogenetic analyses showed that E. ramicornis of Lake Biwa were clearly differentiated from those in previously reported regions and this divergence was estimated to have occurred 1.40 MYA. At that time, there was no lake at the location of present-day Lake Biwa. It is thought that rivers and their dammed flood plains to the east, with gravel and sand supplied by the rising Suzuka Mountains further to the east. Such an environments is preferable for E. ramicornis and they were thought to have become isolated from the surrounding rivers during the formation of Lake Biwa. On the contrary, there was no genetic differentiation between the E. granicollis population at the Lake Biwa inflow rivers and those elsewhere. Hence, E. granicollis might have migrated to the Lake Biwa watershed later than E. ramicornis and maintained gene flow over a wide area. The genetic differentiation of E. ramicornis reported here for the first time suggests that a species with a wide distribution may rather be evolving endemic to Lake Biwa. Reports on the endemism of aquatic insects in ancient lakes are scarce. This study is expected to bring new perspectives to the study of insect evolution in ancient lakes.

“…Aquatic insects are composed of around 76,000 species, found in a wide range of aquatic (and semiaquatic) habitats, from springs, ponds and lakes to large rivers [ 15 , 16 ]. As edible insects, edible aquatic insects have a long history of utilization [ 5 ] too.…”

Edible insects have great potential to be human food; among them, aquatic insects have unique characteristics and deserve special attention. Before consuming these insects, the nutrition and food safety should always be considered. In this review, we summarized the species diversity, nutrition composition, and food safety of edible aquatic insects, and also compared their distinguished characteristics with those of terrestrial insects. Generally, in contrast with the role of plant feeders that most terrestrial edible insect species play, most aquatic edible insects are carnivorous animals. Besides the differences in physiology and metabolism, there are differences in fat, fatty acid, limiting/flavor amino acid, and mineral element contents between terrestrial and aquatic insects. Furthermore, heavy metal, pesticide residue, and uric acid composition, concerning food safety, are also discussed. Combined with the nutritional characteristics of aquatic insects, it is not recommended to eat the wild resources on a large scale. For the aquatic insects with large consumption, it is better to realize the standardized cultivation before they can be safely eaten.
