This research shows how the noise produced by mining affects crickets&rsquo; acoustic communication. Two passive acoustic monitoring devices (SMII) were installed in a forest fragment located at 500 m from the Brucutu Mine in Brazil. Another two SMII were installed distant 2500 from the mine. The equipment was configured to record from 17:00 to 05:00 h during seven days in April 2013. The authors analyzed the spectral characteristics of acoustic activity of three species of crickets (Anaxipha sp., Gryllus sp., and a Podoscirtinae species) before, during, and after the passing of mine trucks. For comparison the authors analyzed the acoustic characteristics for Anaxipha sp. and Gryllus sp. found in the distant site. Results showed a calling interruption for all the species during truck transit. Gryllus sp. emitted calls with higher maximum frequencies, average power, and larger bandwidth in the site close to the mine. Podoscirtinae species emitted calls with lower minimum frequencies, higher average power, and large bandwidth in the close site. The authors show that insect acoustic behavior varies between areas with different levels of noise. The disruption of this behavior may have negative consequences for their reproductive success.</p>

Anthropogenic noise is a stressful factor and can affect behaviour, physiology and acoustic communication of many animal species. However, the noise impact produced by HPP on fishes has not been studied yet. In this research we investigated the noise impact of hydroelectric turbines on the behaviour of Leporinus taeniatus held captive in Brazil. We tested the hypothesis that noise could disturb fishes&rsquo; behaviour by affecting school organization, fish position in the tank and the speed of swimming. Two groups of 10 individuals were exposed to 30 sessions of noise played at an intensity of 100 dB re 1 &micro;Pa, during 40 s on days 0, 7 and 14. Behavioural data were obtained before, during, and after noise exposure. Results showed that the fish swam significantly faster, moving to the bottom and swimming in depolarised shoals during noise exposure in both groups. Temporal analysis showed that during noise exposure fish swam faster, were less stationary and used the bottom of the tanks more throughout sampling period. These data provide evidence that fish behaviour can be affected by the aversive stimulus of the noise of a hydroelectric turbine in operation. It also suggests that sound pollution issues should be taken into consideration when regulating the use of natural areas for HPP.</p>
