“…Some of these focus on specific aspects of impact (TTS and PTS with potential consequences for survival and body condition: Aarts et al 2016; migration speed with potential consequences for delayed or restricted reproduction: Rossington et al 2013), while other studies translate effects from acoustic response on feeding and swimming patterns into bioenergetics consequences (again with potential consequences for survival, body condition and reproduction: Heinänen et al 2018), and consequences at the population level (processing all spatial information and bioenergetic consequences up to the expected changes in population size: Van Beest et al 2017, Nabe‐Nielsen et al 2018). As such, these applications of ABMs to acoustic disturbances are not fundamentally different from spatial investigations into disturbances in general or in other habitats than the marine environment (Brito et al 2017, Jager and DeAngelis 2018, Pirotta et al 2019).…”

Marine ambient sound levels have risen due to noisy human activities, such as shipping, fishing, seismic surveys and piling for windfarms. Marine mammals and fishes are two prominent taxonomic groups that are exposed to this noise pollution, which may experience detrimental effects at the population level. Acoustic effects on individual behaviour such as deterrence, disturbance, distraction and masking of biologically relevant sounds, can be translated energetically to changes in vital rates (growth, maturation, reproduction and survival) in a population consequences of acoustic disturbance (PCAD) approach. However, we typically neglect spatial variation in species distributions and noise pollution, while abiotic factors like temperature, bathymetry and currents, as well as habitat quality in terms of feeding or hiding opportunities, will also have a geographically variable impact on potential consequences. We here address the conceptual integration of agent based models (ABM) into the PCAD framework, as a suitable theoretical tool with high potential for the exploration of these spatial factors and their modifying role in noise impact assessment studies. We review five ABM case studies, including investigations into: 1) effects of movement strategy on the impact of explosions in harbour porpoise; 2) effects of disturbance sensitivity on pile driving impact on migrating cod; 3) impact of seismic survey sounds on Atlantic mackerel distribution and movement; 4) population‐level impact of mitigation of harbour porpoise bycatch with pingers; and 5) population effects of alternative windfarm construction scenarios in harbour porpoise. We discuss similarities and differences among these studies in sound and species mapping approaches and we evaluate model realism and pattern validation. We believe that ABMs are a valuable tool for integrating spatial information into ecological impact studies that investigate acoustic disturbance, for any type of sound source, and for both marine mammals and fish.

“…A theoretical model described by Brito et al (2017) based on individual-based models (IBMs) was used to assess the relationship between exposure to toxicity in the early stages of R. quelen and the impacts on the population dynamics of the species. The model considers three phases: Phase (A) is the embryo-larval stage, which corresponds to the first 96hpf that is characterized by the presence of the yolk vesicle.…”

“…Here the model was parameterized with data from the lowest dilution (33%) groups considering that individuals with deformities reduced the survival rate because they lost the ability to respond to environmental stressors. As proposed by the original study (Brito et al, 2017), for each parameter combination, was considered an initial population composed of 20 individuals and then computed the relative population density, which was define as the adult population size divided by the average population size in a nonperturbative scenario (without pollutants). Was investigated the scenario where: (i) the pollutants affect larvae and juveniles (computing all combinations when 0 S A 0.63 and 0 b 0.8); (ii) the pollutants affect larvae and adults (computing all combination when 0 S A 0.63 and 0 S C 0.65); (iii) the pollutants affect the three phases with the same intensity (I), where I was is the ratio I ¼ S A /0.63 (consequently b ¼ I x 0.8 and S C ¼ I x 0.65).…”

“…Additionally, biomarkers were applied to the early stages of development of R. quelen in order to identify the risk of exposure experienced by the local biota and also by human populations. A theoretical model (Brito et al, 2017) was applied in order to assess information of the impacts on the species population density, related with the water quality and the toxic responses from the early stages of development of R. quelen species.…”

The Iguaçu River is one of the largest and most important rivers in the Southern of Brazil. The Upper Iguaçu Basin is responsible for water supply (80%) of the Metropolitan Region of Curitiba (MRC). After crossing a large urban region, the river is polluted by domestic and industrial sewage, but despite of that few ecotoxicological studies have been performed in order to evaluate the water quality from Iguaçu River. The aim of the present study was to investigate the risk of exposure of Iguaçu water to biota and also human population. In this terms, was utilized the survival effect and the morphological deformities in larval embryos of Rhamdia quelen, a native South America species. The results showed a high level of pollution in all studied sites along the Upper Iguaçu River including PAHs and toxic metals such as lead. The lethal and non-lethal effects described in earlier stages of development suggest an elevated risk to biota. This data was corroborated by the theoretical model, showing that the pollutants present in water from Iguaçu River may further reduce the fish population density including risk of local extinction. The present study reflect the needs to conduct in-depth research to evaluate the real impact of human activities on the endemic fish biota of Iguaçu River including the risk for human populations.

The degradation of water resources available for human consumption is increasing with the continuous release of chemicals into aquatic environments and their inefficient removal in wastewater treatment. Several watersheds in Brazil, such as the Iguaçu River, are impacted by multiple sources of pollution and lack information about their pollution status. The Iguaçu River Basin has great socioeconomic and environmental relevance both for the supply of water resources and its high hydroelectric potential, as well as for the high rate of endemism of its ichthyofauna. Also, it is home to large conservation units, such as the Iguaçu National Park, recognized by Unesco as a Natural Heritage of Humanity. Thus, the current review discusses the chemical pollution in the Iguaçu River Basin (IRB) approaching: i) the main sources of pollution; ii) the occurrence of inorganic and organic micropollutants; iii) the available ecotoxicological data, and iv) the socioeconomic impacts in three regions of the upper, middle, and lower IRB. Different studies reported relevant levels of emerging contaminants, persistent organic pollutants (POPs), toxic metals, and polycyclic aromatic hydrocarbons (PAHs), detected in the water and sediment samples, especially in the upper IRB region, associated with domestic and industrial effluents. Additionally, significant concentrations of pesticides and toxic metals were also detected in the lower IRB, revealing that agricultural practices are also relevant sources of chemicals for this watershed. More recently, studies indicated an association between fish pathologies and the detection of micropollutants in the water and sediments from IRB. The identification of the main sources of pollutants, associated with the distribution of hazardous chemicals in the IRB and their potential effects on the biota, as described in this review, represents an important strategy to support water management by public authorities for reducing potential risks of the local endemic biodiversity and exposed human populations.
