“…This behavior validates the avoidance tests because it indicates that there is no other environmental factor (associated either to the laboratory conditions, to the exposure system, or to the shrimps' behavior) influencing habitat selection by the shrimps. Previous studies using nonforced exposure systems with different organisms, such as shrimps, tadpoles, and fish, have also shown that organisms presented a random distribution with no preference for any compartment of the system in the absence of a contaminant (Moreira-Santos et al 2008;Ara ujo et al 2014Ara ujo et al , 2016aAra ujo et al , 2018Silva et al 2018).…”

Bioassays using the nonforced exposure approach have been shown to be a relevant tool that might complement the traditional ecotoxicological risk assessment. Because the nonforced exposure approach is based on spatial displacement of organisms and the consequent habitat selection processes, the population density might play an important role in the decision to avoid or prefer an ecosystem. Therefore, the aim of the present study was to assess if the avoidance response to contamination, measured in a nonforced exposure system, is density‐dependent and how determinant contamination could be for the habitat‐selection process in comparison with the population density. The freshwater shrimp Atyaephyra desmarestii was exposed to a copper gradient in a nonforced exposure system formed by 7 interconnected compartments (total volume 600 mL), which contained different copper concentrations. The density treatments used were 3, 5, and 10 organisms per compartment, corresponding to 0.5, 0.8, and 1.7 organisms per 100 mL, respectively. Clearly, the avoidance response to copper was more intense in the population with the lower density: the highest population density showed the lowest avoidance. The concentrations that triggered an avoidance of 50% of the population were 47, 134, and 163 μg L−1. In summary, it was observed that shrimps were able to detect and avoid potentially toxic copper concentrations but that the avoidance response was affected by population density.

“…It was expected that the less aggressive species would be displaced towards previously avoided contaminated habitats. Copper (Cu 2+ ) was selected as a test contaminant as it is an avoidable pollutant for fish (Moreira-Santos et al, 2008;Araújo et al, 2015) and produces toxic effects such as chemosensory deprivation (McIntyre et al, 2008), changes in gene expression (Craig et al, 2010), feeding inhibition (Abdel-Moneim et al, 2015), effects on the swimming performance of larvae (Acosta et al, 2016), morphological and metabolic alterations (Chatterjee et al, 2016), and changes in the surfaces of the gills (Fu et al, 2016). P. reticulata and D. rerio were selected as test organisms because they (i) are easy to cultivate, (ii) are widely used as model organisms in the fields of ecology, evolution, and ethology, and (iii) have already been shown to spatially avoid chemical contamination (Moreira-Santos et al, 2008;Silva et al, 2017).…”

An increasing number of studies have shown the ability of organisms to escape from toxic effects due to contamination, by moving spatially towards less contaminated habitats. However, this issue has been investigated in monospecific scenarios, without considering possible interactions between species during the contamination avoidance process. It is widely known that the spatial distribution of one species can be affected by another one, in different ways. Therefore, the main question addressed in the present study was as follows: Might interspecific interaction between the freshwater fish Danio rerio (zebrafish) and Poecilia reticulata (guppy) change their behavior patterns in terms of avoidance in the presence of a copper gradient? Zebrafish and guppies exposed to a copper gradient were tested for avoidance responses in a free-choice, non-forced, static, multi-compartmented exposure system, using two distinct approaches: (1) monospecific tests, in which only one species was exposed to the copper gradient, at two different population densities; and (2) multispecific tests, in which both species were tested simultaneously. In the control (with no copper) monospecific tests, both species were randomly distributed; however, in the control multispecific test, P. reticulata tended to aggregate. In the monospecific tests with a copper gradient, both species avoided copper in a similar way, with AC (concentration triggering avoidance in 50% of the exposed population) values between 15 and 18 μg·L, irrespective of the population density. However, in the multispecific tests, P. reticulata displaced D. rerio to previously avoided copper levels, consequently increasing the AC of D. rerio to 75 μg·L. This study shows the importance of understanding the interactions among species in contaminated areas, and the way that one species can prevent the avoidance behavior of another.
