[ 1 ] - Effects of light and sound stimuli on spatial distribution and swimming activity of Daphnia under laboratory conditions

Aquatic ecosystems are heterogeneous in terms of light and sound distribution. The aim of this study was to investigate the effect of environmental abiotic factors, light and sound stimuli, on Daphnia (Daphnia magna) swimming behaviour.  Here, we examined behavioural changes of Daphnia (N=24) in response to light and sound treatments simultaneously. The treatments concerned a 2×2 design with br...

[ 2 ] - The influence of sound exposure on movement and food-finding behaviour of red cherry shrimp Neocaridina davidi

Background and Objectives: Many animal species are currently experiencing anthropogenic pollutions in their habitat. Noise pollution from human activities affects many species of animals. Noise pollution in terrestrial and aquatic ecosystems is prominently recognized as a source of stress and disruption of biological activities, and an important and pervasive global environmental pollutant.
