We conclude that experimental data and computational modeling matched. Finally, it was possible to model the behavior of the larvae under the effects of chlorpyrifos. During the interaction phase, the larvae continued to show sound effects, however, the antipredator mechanism continued to be operating and efficient. Also, it induced effects on the sounds emitted after 96В h of exposure, registering a smaller number of pulses and higher dominant frequencies, and altered intra- and inter-specific interactions. During the exposure phase, chlorpyrifos induced significant mortality from 48В h (48В h: pВ <В 0.05, 72В hвЂ“96В h: pВ <В 0.001), irregular swimming, tail flexure, and the presence of subcutaneous air.

Also, intraspecific interactions of three Co tadpoles under different conditions of exposure were evaluated (Experiment II: 3 exposed Co, 2 exposed Co/1 non-exposed, 1 exposed Co/2 non-exposed). ornata ( Co) tadpoles acting as predators and unexposed Rhinella fernandezae ( Rf) tadpoles acting as prey (Experiment I), under different predator-prey proportions (0/10В =В 0 CoвЂ“10 Rf, 2/8, 4/6, 6/4, 8/2, 10/0).

The second phase consisted of evaluating the effects of CPF on intra- and inter-specific interactions of exposed C. If playback doesnt begin shortly, try restarting your device. Experiments were developed under two consecutive phases: a first phase of exposure (treated and control group), and a second phase of interactions. Considering the increasing interest in the effects of pesticides on behavioral traits, the aim of this study was to evaluate the effects of chlorpyrifos (CPF) on intra- and inter-specific interactions of anuran tadpoles, complementing traditional ecotoxicological tools with a theoretical analysis verified by computational simulations. The computational modeling is a complementary useful and predictive tool that overcomes these limitations. Large-scale ecotoxicological studies have technical and ethical limitations, both related to the need to expose large numbers of individuals to potentially harmful compounds. Other sounds that animals interpret as originating from either predators or aggressive conspecifics may evoke disturbance responses similar to those that.
