“…Using a permutational analysis of variance (PERMANOVA), we tested whether the compressor factor or background dB level caused differences in the Bray–Curtis or Cao dissimilarity matrices calculated from abundance data at the family and genus levels (program R, CRAN package: VEGAN). Families or genera that only occurred at one site were excluded from PERMANOVA analyses (Ohwaki, ), and for the Bray–Curtis analyses the abundance data were square‐root‐transformed to reduce leverage by dominant taxa (program R, CRAN package: VEGAN; Davies et al., ). Finally, nonmetric multidimensional scaling (NMDS) was used to visualize the relationships of the sites with one another using the full datasets and Bray–Curtis dissimilarity.…”

Anthropogenic noise is a widespread and growing form of sensory pollution associated with the expansion of human infrastructure. One specific source of constant and intense noise is that produced by compressors used for the extraction and transportation of natural gas. Terrestrial arthropods play a central role in many ecosystems, and given that numerous species rely upon airborne sounds and substrate‐borne vibrations in their life histories, we predicted that increased background sound levels or the presence of compressor noise would influence their distributions. In the second largest natural gas field in the United States (San Juan Basin, New Mexico, USA), we assessed differences in the abundances of terrestrial arthropod families and community structure as a function of compressor noise and background sound level. Using pitfall traps, we simultaneously sampled five sites adjacent to well pads that possessed operating compressors, and five alternate, quieter well pad sites that lacked compressors, but were otherwise similar. We found a negative association between sites with compressor noise or higher levels of background sound and the abundance of five arthropod families and one genus, a positive relationship between loud sites and the abundance of one family, and no relationship between noise level or compressor presence and abundance for six families and two genera. Despite these changes, we found no evidence of community turnover as a function of background sound level or site type (compressor and noncompressor). Our results indicate that anthropogenic noise differentially affects the abundances of some arthropod families. These preliminary findings point to a need to determine the direct and indirect mechanisms driving these observed responses. Given the diverse and important ecological functions provided by arthropods, changes in abundances could have ecological implications. Therefore, we recommend the consideration of arthropods in the environmental assessment of noise‐producing infrastructure.

The article presents materials of perennial (1988–2017) studies on solving problems of stabilizing the phytosanitary situation in irrigated agrocenoses. The paper presents the results of studying the species abundance and insects, the patterns of their change under the influence of irrigation in the Lower Volga region. The effect of irrigation on the change in environmental conditions by the parameters of productivity of agrobiocenoses and microclimate is shown. The difference in air temperature in irrigated by sprinkling and non-irrigated agrocenoses immediately after watering reaches 7-8° C. In general, during the growing season, the average daily air temperatures in the irrigated agrocenosis were 2-4° C lower, compared to the non-irrigated. More mesophytic microclimatic conditions, which are formed under the influence of irrigation, are the leading factor determining the increase in the biodiversity of the entomocomplexes of irrigated agrocenoses due to an increase in species abundance and the number of mesophilic and hygrophilic insects. An increase in species diversity and abundance of meso-and hygrophilic in irrigated agricultural landscapes due to the emergence of new micro-sites (canals, spillways, storage ponds, etc.) is also shown. The formation of irrigated conditions in poly-dominant entomological communities, which increase the balance of the agroecosystem, including by optimizing its trophic structure. The changing ecological situation in irrigated agricultural landscapes determines the cultivation of plants with optimized physiological indicators, and the biological characteristics of the development of harmful and beneficial insects change under irrigation conditions. All this directly affects the relationship between phytophages and plants, as well as their survival, fertility, life expectancy of individual phases and other biological features of populations. It is noted that on irrigated crops there is a more favorable relationship between entomophages and pests, making it possible to self-regulate the entomofauna due to increased activity of entomophages. This creates a real opportunity to save the crop and reduce the pesticide load by 40-50% on irrigated crops.
