“…In contrast, the increased averaged juvenile body length along the high‐biomass state (Figure 3d) is attributed to fast drop of population recruitment of newborn individuals (Figure 4d) (e.g. Cormier et al., 2021, 2022), which weakens resource competition among juveniles (Figure 4b), and hence increases food uptake as well as fast growth rate consequently (Figure 4c).…”

Microplastics can be ingested by a wide range of aquatic animals. Extensive studies have demonstrated that microplastic ingestion—albeit often not lethal—can affect a range of species life‐history traits. However, it remains unclear how the sublethal effects of microplastics on individual levels scale up to influence ecosystem‐level dynamics through cascading trophic interactions. Here we employ a well‐studied, empirically fed three‐species trophic chain model, which was parameterized to mimic a common type of aquatic ecosystems to examine how microplastic ingestion by fish on an intermediate trophic level can produce cascading effects on the species at both upper and lower trophic levels. We show that gradually increasing microplastics in the ingested substances of planktivorous fish may cause population structure effects such as skewed size distributions (i.e. reduced average body length vs. increased maximal body size), and induce abrupt declines in fish biomass and reproduction. Our model analysis demonstrates that these abrupt changes correspond to an ecosystem‐level tipping point, crossing which difficult‐to‐reverse ecosystem degradation can happen. Importantly, microplastic pollution may interact with other anthropogenic stressors to reduce safe operating space of aquatic ecosystems. Our work contributes to better understanding complex effects of microplastic pollution and anticipating tipping points of aquatic ecosystems in a changing world. It also calls attention to an emerging threat that novel microplastic contaminants may lead to unexpected and abrupt degradation of aquatic ecosystems, and invites systematic studies on the ecosystem‐level consequences of microplastic exposure.

“…African catfish ( Clarias gariepinus ) exposed to 0.5, 1.0, and 1.5 g of low-density polyethylene (PE) showed an affected survival and swimming ability [ 55 ]. Short-term exposure (4–96 hpf) to MPs (1 or 10 mg/L) in the early life stage of zebrafish resulted in only weak toxic effects, whereas long-term (4 months) exposure led to a reduction in the body weight of the parents and their offspring’s swimming behavior [ 77 ]. Therefore, MNPs do not only affect the parents but also affect the growth and behavior of their offspring through their accumulation [ 46 , 78 ].…”

The escalating prevalence of microplastics and nanoplastics in aquatic environments is a major challenge affecting the behavior and reproductive health of aquatic organisms while posing potential risks to human health and ecosystems. This review focuses on the neurobehavioral changes and reproductive toxicity of MNPs in zebrafish and their relationships. At the same time, the neurobehavioral changes caused by MNPs were studied, and the synergistic effects of the interaction of these pollutants with other environmental contaminants were explored. In addition, zebrafish, as a model organism, provide valuable insights into the subtle but important effects of MNPs on reproductive behavior, which is critical for understanding reproductive success, suggesting that behavioral changes can serve as an early biomarker of reproductive toxicity. In addition, based on classical endocrine disruptor models and behavioral research methods, the current status of the research on the reproductive toxicity of MNPs in zebrafish was reviewed, which further indicated that the behavioral parameters of zebrafish can be used as an effective and rapid tool to evaluate the reproductive toxicity of MNPs. However, behavioral methods for rapidly assessing the toxicity of MNPs are still an area of exploration. To address limitations and challenges in the current scope of research, this review outlines future research directions with the aim of improving our understanding of the environmental and health impacts of MNPs. This work aims to inform targeted environmental policies and advance public health strategies to address the growing challenge of MNPs pollution.

“…The object of the DHC study is free-living (autochthonous) zooplankton and ecosystem functions based on plankton concentration on a certain spatial scale (DHC working volume) but representing the long monitoring series of measurements. Due to the different rate of plankton community interaction with environmental factors [5,6,13,14,[24][25][26][27][28][29][30][31][32], including the appearance of pollutants, it is possible to use the ecosystem functions that are different in terms of responsiveness.…”

The study presents a bioindication complex and a technology of the experiment based on a submersible digital holographic camera with advanced monitoring capabilities for the study of plankton and its behavioral characteristics in situ. Additional mechanical and software options expand the capabilities of the digital holographic camera, thus making it possible to adapt the depth of the holographing scene to the parameters of the plankton habitat, perform automatic registration of the “zero” frame and automatic calibration, and carry out natural experiments with plankton photostimulation. The paper considers the results of a long-term digital holographic experiment on the biotesting of the water area in Arctic latitudes. It shows additional possibilities arising during the spectral processing of long time series of plankton parameters obtained during monitoring measurements by a submersible digital holographic camera. In particular, information on the rhythmic components of the ecosystem and behavioral characteristics of plankton, which can be used as a marker of the ecosystem well-being disturbance, is thus obtained.
