“…Many soil invertebrates have been known to show strong avoidance response to single and mixtures of toxicants. Earthworms , collembola , oribatid mites , and isopods could avoid contaminants at concentrations similar to that for which effects are found on reproduction or survival. For enchytraeids, initial trials with Enchytraeus albidus indicate some promise, but later trials showed lower sensitivity than reproduction and with large data variation, thereby discouraging their use in the context of risk assessment and suggesting a need to consider other enchytraeid species.…”

Few toxicity data exist in the literature on the toxicity of chemicals to the predatory mite Hypoaspis aculeifer, but no information is available on its avoidance response. To assess the relevance of the avoidance behavior of H. aculeifer and the relative sensitivity of the mite in comparison with other invertebrates, avoidance and reproduction tests were conducted with 7 chemicals using standardized guidelines. The chemicals (deltamethrin, chloropyrifos, dimethoate, Cu, NaCl, phenanthrene, and boric acid) were selected so as to cover varying chemical classes. For all 3 pesticides tested, avoidance response showed lower sensitivity than reproduction and survival (avoidance median effective concentration [EC50] > reproduction EC50/median lethal concentration [LC50] values). However, for Cu, NaCl, and phenanthrene, the avoidance response showed similar sensitivity as reproduction (avoidance EC50 ≤ reproduction EC50 values), whereas for boric acid, similar sensitivity as survival (avoidance EC50 ≤ LC50 values). Although the mite H. aculeifer appears less sensitive to some of the chemicals tested than most other soil invertebrates, its status as the only predator among organisms for which standardized tests are available affirms its inclusion in routine ecotoxicity assessment. The results of the avoidance test with H. aculeifer suggest its potential usefulness as a rapid screening test for risk assessment purposes.

“…Also known as the compost springtail, F. candida is found in forests and grasslands throughout North America and Europe (Römbke et al., ). The development of behavior‐based tests, such as soil contamination avoidance bio‐assays, has generated interest in studies of its short‐distance dispersal ecology (Martinez Aldaya et al., ; Auclerc et al., ; Boiteau et al., ). Boiteau & MacKinley (, ) have suggested that F. candida does not respond to cooling temperatures by relocating to warmer deeper soil layers but by acclimation.…”

Laboratory assays demonstrated the presence of a small positive geotaxis response to a 15° incline by Folsomia candida Willem (Collembola: Isotomidae). Negative phototaxis played an additive role to positive geotaxis when the experimental apparatus were exposed to light. The geotactic response was negatively affected by cold acclimation and decreasing surrounding temperature, but unaffected by food deprivation. The reduced mobility of springtails at low temperature did not seem to play a role in the corresponding decreased geotaxis. The low level of geotaxis and its further decrease with exposure to low temperature support an earlier suggestion that F. candida do not respond to cooling temperatures of fall by relocation to warmer deeper soil layers, but remain in the upper soil layers and increase their cold tolerance to continue foraging in the food‐rich upper soil layers.

“…This species is used as a standard test organism for toxicity tests: A 28-d reproduction test [23] is included in the refinement options for ecological risk assessment of plant protection products to soil organisms in the European Union [24]. Copper sulfate (CuSO 4 ) was used as a model contaminant to simulate permanent loss of habitat quality, because it is proven to cause toxic effects to F. candida survival and reproduction, and to elicit behavioral responses such as avoidance [25]. Moreover, it is used as fungicide on a variety of crops, is one of the most widely distributed pollutant among metals, and is therefore relevant for ecological risk assessment.…”

The authors implemented a fractal algorithm in a spatially explicit individual-based model to generate landscapes with different microscale patterns of habitat fragmentation and disturbance events and studied their effects on population dynamics of the collembolan Folsomia candida. Among human activities that may cause habitat destruction, the present study focused on agricultural practices. Soil organisms living in a cultivated field are subjected to habitat loss and fragmentation as well as disturbance events generated by the application of agrochemicals and related activities. In addition, they are exposed to natural stressors, which might influence the effects of chemicals on populations. The authors designed simulation experiments that incorporate these 3 factors and investigated their effects on populations of F. candida in the presence or absence of behavioral avoidance of contaminated habitat. Simulation results show that spatial autocorrelation of contamination has different effects on population growth and equilibrium size according to the percentage of clean habitat. This pattern changes when avoidance behavior is excluded from the model, as does population recovery after a series of disturbance events. The model suggests that a combination of heterogeneous contamination and multiple stressors can lead to unexpected effects of toxicants at the population level. Individual-based models can help to understand these effects and therefore add ecological realism to environmental risk assessment of chemicals and can help to explore the effects of different risk management options.
