“…In the case of deltamethrin exposure, behavior strength changed with exposure time and concentration. Higher concentrations resulted in a greater degree of the behavioral responses, as well as a shorter response time for the first phase behavioral response, which was regarded as avoidance behavior (Sager et al 2000;Erik et al 2005;Eriksson Wiklund et al 2006). Even in the sublethal concentrations (0.1 TU), the first phase behavioral response could be detected.…”

“…Avoidance that varied with time and concentration upon organisms is an important defense mechanism in organisms, and higher concentrations of contaminants would lead to increased avoidance (Pedder and Maly 1985). Many studies on avoidance response that was regarded as one of the most important behavioral responses of organisms to different contaminant stress had been reported (West and Ankley 1998;Lefcort et al 2004;Eriksson Wiklund et al 2006). There was hardly discusses on the on the duration of avoidance response (DAR), which was defined as time between beginning of the exposure and a significant decrease (20%) in behavior strength (Fig.…”

“…Changes in the movement behavior of organisms can therefore be used as a suitable indicator in ecotoxicological risk assessment. According to previous research (Steele et al 1989;Saglio and Trijasse 1996;Eriksson Wiklund et al 2006), avoidance of the organism to contaminants is an adaptive behavior that may reduce exposure to harmful conditions and failure to avoid exposure may result in reduced fitness and survival, eventually leading to detrimental effects. The movement patterns of Daphnia magna have many different components and the behavioral responses of Daphnia magna to different contaminants are reported (Untersteiner et al 2003;Reynaldi et al 2006).…”

Behavioral Responses of Daphnia Magna to Stresses of Chemicals with Different Toxic Characteristics

Behavior of an organism is affected by exposure to toxic chemicals. However, less has been known about behavioral responses of an organism to stresses of toxic chemicals with different toxic characteristics. In present work, Daphnia magna Straus was exposed to gradient concentrations of deltamethrin, chlorothalonil and nitrofen and the behavioral changes of Daphnia magna under different stress were examined. The results showed that the behavioral responses of Daphnia magna to the tested chemicals were affected in general by exposure concentration, rather than toxic characteristics of the chemicals. The duration of avoidance response (DAR) was in a power regression relationship with the toxic unit (TU), defined as the ratio of exposure concentration of the tested chemical to its LC . DAR was independent of the toxic characteristics of chemicals. However, significant behavior adjustment could be observed after exposure to deltamethrin while only step-by-step decrease in behavior strength could be observed when exposed to chlorothalonil and nitrofen. It was suggested from the observation that avoidance behaviors of Daphnia magna to exposures of chemicals with different toxic characteristics could be similar, while their specific response could be different.

“…Different behaviors of different species had different toxicant sensitivity, but the first behavioral response to the stress, by which organisms tried to escape from the pollution source with higher behavior strength, was the general behavior adaptation of organisms, and it was defined as "avoidance behavior" [7,8,24]. Therefore, according to the results of the behavioral responses of D. magna to OP stress, avoidance behavior was mainly made up of no effects and stimulation actions in Fig.…”

The Avoidance Responses of Daphnia magna to the Exposure of Organophosphorus Pesticides in an On-Line Biomonitoring System

In this study, avoidance behavior of the freshwater cladoceran Daphnia magna Straus was used as indicator to assess the early stress of accidental organophosphorus pesticide (OP) contamination. The movement behavior was detected by a multi-species biomonitoring system. There was obvious concentration-response relationship between the OP stress and the behavioral response even at sublethal exposure. A rising OP stress resulted in a significant decrease of response time to escape (RTE; p<0.05). In comparison of different OPs, it was found that there was a power regression between RTE and the toxic unit of OPs. Therefore, the avoidance behavior of D. magna was a sensitive indicator of sublethal OP stress, and the power relationship could be used to predict the early warning thresholds of more OPs in the on-line biomonitoring system.

Abstract-The distribution of contaminants is seldom homogeneous in aquatic systems. In the present study, the avoidance response of Melita plumulosa, Nitocra spinipes, and Phallomedusa solida when exposed to contaminated sediments was investigated. Test vessels were designed to allow the congruent placement of two sediments and assessment of the movement of organisms between the sediments. When exposed to reference sediment, each species dispersed evenly between test chambers regardless of differences in sediment particle size. In the presence of contaminated sediment, the magnitude and rate of avoidance varied. Avoidance assays showed that test species avoided contaminated sediment as early as 6, 6, and 24 h following exposure for N. spinipes, P. solida, and M. plumulosa, respectively. The 48-h avoidance response of M. plumulosa for nine contaminated sediments of varying toxicity showed that avoidance was generally greater for sediments which elicited greater 10-d lethality to this species. The study demonstrated that each of these species has the ability to respond to chemical cues in the environment to inhabit sediment that provides the best opportunity for survival. The avoidance response for each species indicates the potential for developing rapid screening methods to assess sediment quality. Evidence suggests that avoidance was related to sediment toxicity and that static 10-d toxicity methods are likely to overestimate toxicity for species, which would avoid contamination in heterogeneous field settings.
