“…For example, Martin (2004), who studied Drosophila movement from video records, chose the threshold by trying a range of values. Kane et al (2004) defined a fish as moving if the fish moved approximately half of its length per second. Arbitrary choice of the threshold value inevitably introduces an element of subjectivity in the analysis.…”

Power laws are increasingly used to describe animal movement. Despite this, the use of power laws has been criticized on both empirical and theoretical grounds, and alternative models based on extensions of conventional random walk theory (Brownian motion) have been suggested. In this paper, we analyse a large volume of data of aphid walking behaviour (65 068 data points), which provides a highly resolved dataset to investigate the pattern of movement. We show that aphid movement is intermittent-with alternations of a slow movement with frequent change of direction and a fast, relatively directed movement-and that the fast movement consists of two phases-a strongly directed phase that gradually changes into an uncorrelated random walk. By measuring the mean-squared displacement and the duration of non-stop movement episodes we found that both spatial and temporal aspects of aphid movement are best described using a truncated power law approach. We suggest that the observed spatial pattern arises from the duration of non-stop movement phases rather than from correlations in turning angles. We discuss the implications of these findings for interpreting movement data, such as distinguishing between movement and non-movement, and the effect of the range of data used in the analysis on the conclusions.

Key-words:Astacus leptodactylus, cardiac activity, heart rate, salinity, stress reaction A non-invasive method of recording cardiac activity (heart rate -HR) and stress reaction (stress index -SI) was used to understand the immediate and ongoing stress reaction of crayfish to the chemical stimuli. This method detects changes in the shape and amplitude parameters of the response to the stress factors, which characterized the crayfish functional state. Experimental animals (Astacus leptodactylus) were divided to the two groups with (400 mg·L −1 Cl − ) and without added chlorides and then exposed to a stepwise increased level of nitrite to the final (sublethallethal) concentration of 60 mg·L −1 N-NO − 2 within 24 hours. The course of crayfish reaction was evident and provided information about their reaction to the sublethal-lethal concentration over time. As expected, a less prominent stress reaction was detected in the group with chlorides. The non-invasive method successfully evaluated the sensing of chemical stimuli in water through HR and SI changes. RÉSUMÉRéaction au stress chez l'écrevisse : les chlorures aident à résister au stress dans des conditions de fortes concentrations en nitrite -étude préliminaire Mots-clés :Astacus leptodactylus, activité cardiaque, rythme cardiaque, salinité, réaction au stress Une méthode non-invasive d'enregistrement de l'activité cardiaque (rythme cardiaque -HR) et de réaction au stress (indice de stress -SI) a été utilisée pour comprendre la réaction au stress immédiate et ultérieure de l'écrevisse à des stimuli chimiques. Cette méthode détecte les changements dans la forme et l'amplitude des paramètres de la réponse aux facteurs de stress, qui caractérisent l'état fonctionnel de l'écrevisse. Les animaux de l'expérience (Astacus leptodactylus) ont été divisés en deux groupes avec (400 mg Cl − ·L −1 ) et sans chlorures ajoutés puis exposés à des niveaux croissants par paliers de nitrite jusqu'à la concentration finale (sub-létale-létale) de 60 mg·L −1 N-NO − 2 pendant 24 heures. La réaction de l'écrevisse est évidente et fournit des informations sur les réactions au cours du temps à une concentration sub-létale. Comme escompté, une réaction au stress moins marquée est détectée dans le groupe avec des chlorures. La méthode noninvasive a déterminé correctement l'impact du stimulus chimique de l'eau par les changements de HR et SI.

“…With the vast improvements in the computational capability of personal computers and the implementation of reliable image processing techniques, the visual monitoring of fish behavior has becomes a common tool for biological and environmental studies, e.g., exploiting the fish behavior for environmental risk assessments and their responses under specific stimulation, such as chemical stress analysis (Barry, 2012;Kane et al, 2004;Ma et al, 2010). A number of video surveillance systems have been developed for automatic observations and measurements of fish behavior since the 1990s (Delcourt et al, 2013;Kato et al, 1996;Kuklina et al, 2013;Papadakis et al, 2012;Suzuki et al, 2003).…”

a b s t r a c t a r t i c l e i n f oArticle history: Received 8 January 2015 Received in revised form 7 July 2016 Accepted 12 July 2016 Available online xxxx A novel scheme for the behavioral monitoring of multiple fish is presented based on measurements of the fish posture. Image identification of the fish head and tail is proposed by examining the gray level appearance features. A simplified posture of fish was calculated from its head and centroid. Multiple individual tracking was developed by incorporating the fish posture and global nearest neighbor. The proposed tracking scheme was tested with 2-5 individual Zebra fish (Cyprinidae, Danio rerio) under laboratory conditions. The experimental results confirmed the stability of the identification of a fish head and tail and a robust tracking performance was achieved. The proposed method could accurately record the movement trajectories and posture information of each individual. The tracking errors were only 0.278%-1.572% for 2-5 individual fish while the posture measurement error rates were less than 0.16%. Furthermore, the movement patterns of the fish, e.g., angular variations and distribution of the movement angle, were investigated from the behavioral data, which revealed the advantages of the proposed posture measurement for behavioral studies. The aggregation behavior of multiple fish was also analyzed to reveal the interaction patterns of the individuals in response to the spatial formation of the neighbors.
