Effects of Nautical Traffic and Noise on Foraging Patterns of Mediterranean Damselfish (Chromis chromes)
2012
Chromis chromis is a key species in the Mediterranean marine coastal ecosystems where, in summer, recreational boating and its associated noise overlap. Anthropogenic noise could induce behavioural modifications in marine organisms, thereby affecting population dynamics. In the case of an important species for the ecosystem like C. chromis, this could rebound on the community structure. Here, we measured nautical traffic during the summer of 2007 in a Southern Mediterranean Marine Protected Area (MPA) and simultaneously the feeding behaviour of C. chromis was video-recorded, within both the no-take A-zone and the B-zone where recreational use is allowed. Feeding frequencies, escape reaction…
First proposal of a methodology for a preventive assessment of the acoustic impact of advanced landfills
2005
In this paper, the results of a preliminary study on the environmental noise pollution of a technologically advanced landfill to be realized in Sicily (Italy) are presented. The investigation has been carried out analysing, at the beginning, a simulating model suggested by the European Community. The method makes reference to the ISO 9613-2:1996 standard, which suggests a general method of calculation to assess the attenuation of sound during propagation outdoors. The simulation has pointed out the troubles in carrying out the noise pollution assessment of an advanced landfill, where several and different kinds of sound sources are present at the same time; it isn’t always possible, for exa…
