ClearDiscussing Behavioural Ecotoxicology in the Light of Some Environmentally Available Anthropogenic Contaminants and their Influence on Behavioural Alterations in Animals
This review paper summarizes research showing that common pollutants like pesticides, heavy metals, plastics, and pharmaceuticals can change how animals behave by affecting their nervous systems. Scientists study these behavioral changes in animals because they help us understand how these same pollutants might harm brain function in humans. This research is important because it gives us early warning signs about which environmental chemicals could be damaging our health.
Linking animal behavior to ecosystem change in disturbed environments
This review explores how environmental disturbances cause animals to change their behavior, and how those behavioral shifts cascade through species interaction networks to affect entire ecosystems. The study provides a conceptual framework linking individual behavioral responses to broader ecological consequences, suggesting that understanding these connections can improve predictions about human impacts on ecosystems.
Neurophysiological and Behavioral Effects of Micro- and Nanoplastics in Aquatic Organisms
Researchers reviewed evidence that micro- and nanoplastics in aquatic environments cross the blood-brain barrier, accumulate in neural tissues, and cause oxidative stress, neuroinflammation, and disrupted neurotransmitter signaling, with downstream effects on locomotion, feeding, predator avoidance, and social behavior across multiple aquatic species.
Global change ecology: Science to heal a damaged planet
This paper summarizes progress in the field of global change ecology and charts future directions, covering how human activities have altered the Earth's biophysical systems and how organisms and ecosystems are responding to multiple simultaneous stressors.
Nutritional physiology and ecology of wildlife in a changing world
This review examined how environmental change — including chemical pollution and habitat degradation — affects the nutritional physiology and ecology of wildlife, providing a broad framework for understanding pollutant impacts on animal health.
Consequences of Anthropogenic Changes in the Sensory Landscape of Marine Animals
This review examines how anthropogenic activities such as noise, light, chemical, and climate change are altering sensory cues in marine environments, impairing the ability of marine animals to navigate, find food, avoid predators, and reproduce.
Climate Change, the Exposome and the Rising Burden of Neurodegenerative Diseases: A Review
This review examines how climate change-driven events such as wildfires, flooding, and heat waves alter human exposure to environmental neurotoxicants including microplastics, heavy metals, and air pollutants, contributing to rising rates of neurodegenerative disease. It argues for an exposome-based framework that integrates climate and chemical risk assessment.
Micro- and nanoplastics in neurological dysfunction
This review examines growing evidence that micro- and nanoplastic particles can interfere with the nervous system across multiple species, including humans. Researchers found that plastic particles may disrupt cellular metabolism, affect brain development, and increase vulnerability to neurodevelopmental disorders and neurodegeneration. The authors highlight significant knowledge gaps that need to be addressed to understand the long-term neurological impacts of plastic particle exposure.
The effects of micro- and nanoplastics on the central nervous system: A new threat to humanity?
This review summarizes growing evidence that micro- and nanoplastics can cross the blood-brain barrier and damage the central nervous system through inflammation, oxidative stress, and disruption of brain chemicals. The authors note that microplastic exposure has been linked to memory and behavior changes in animals and may contribute to neurodegenerative diseases like Parkinson's, though direct human evidence is still limited.
Ecological disturbances and abundance of anthropogenic pollutants in the aquatic ecosystem: Critical review of impact assessment on the aquatic animals.
This critical review assessed the ecological disturbances caused by anthropogenic pollutants including microplastics in aquatic ecosystems, examining uptake, accumulation, and biological effects across invertebrate and vertebrate species, and identifying gaps in understanding of long-term ecotoxicological impacts at environmentally relevant concentrations.
Environmental exposure pathways of microplastics and their toxic effects on ecosystems and the nervous system
This review examines the environmental pathways by which microplastics enter the human body through ingestion, inhalation, and skin contact, with a particular focus on their effects on the nervous system. Researchers summarize evidence that microplastics can cross the blood-brain barrier and may trigger neuroinflammation and oxidative stress in brain tissue. The study highlights the nervous system as a key area of concern for microplastic-related health research.
Behavioural responses of fishes to anthropogenic disturbances: Adaptive value and ecological consequences
This review presents a framework for understanding how human activities such as pollution, habitat modification, and noise affect fish behavior and how those behavioral changes cascade to affect populations and ecosystems. Researchers found that while many studies document behavioral impacts on fish, very few examine the broader ecological consequences. The study emphasizes that behavioral responses to disturbances can profoundly alter species interactions and ecosystem functioning.
Review Article: Ecotoxicological Impacts of Pollution on Biodiversity and Ecosystem Health in the Anthropocene
This review examines how Anthropocene-era pollutants—heavy metals, pesticides, pharmaceuticals, and microplastics—enter ecosystems, bioaccumulate through food chains, and threaten biodiversity and ecosystem functionality.
From environment to brain: the role of microplastics in neurobehavioral disorders
This review examines how microplastics enter the human body and cross the blood-brain barrier, linking their presence in neural tissue to neurobehavioral disorders through mechanisms including neuroinflammation, oxidative stress, and disruption of neurotransmitter systems.
Plastics and their derivatives are impacting animal ecophysiology: A review
This review examines how microplastics interact with marine life through ingestion, entanglement, and chemical leaching, disrupting organisms from plankton to large fish. The paper highlights that plastic pollution in the ocean directly connects to human health through the food chain, as contaminated seafood transfers microplastics and their toxic additives to people who eat it.
Frontiers in quantifying wildlife behavioural responses to chemical pollution
Researchers investigated how chemical pollution affects wildlife behavior, arguing that conventional study approaches are insufficient and calling for new frontiers in quantifying behavioral responses to contaminants in free-living animal populations.
