ABSTRACT Some individuals have a disproportionate effect on group responses. These may possess distinct attributes that differentiate them from others. characteristics include susceptibility to contaminant exposure such as cadmium, potent trace metal present in water and food. Here, we tested whether pair of cadmium-exposed could exert an impact the behavior unexposed majority. We used behavioral assessments characterize extent effects boldness, cohesion, activity responses landmarks. found groups with fish approached remained closer novel stimuli landmarks than did pairs treated uncontaminated (control). Shoals cadmium exhibited similar levels cohesion activity. The results suggest acutely exposed environmentally-relevant concentrations can profound un-exposed

Anthropic activities have significantly elevated cadmium levels, making it a significant stressor in aquatic ecosystems. Present high concentrations across water bodies, is known to bioaccumulate and biomagnify throughout the food chain. While toxic effects of on organs tissues species are well-documented, little about its impact sensory systems crucial for survival. Consequently, this study investigated short-term exposure (96 h) 25 µM chloride olfactory system adult zebrafish. The research aimed assess structural functional changes zebrafish's lamellae, providing deeper understanding how affects sense smell species. After exposure, cyto-anatomical alterations lamellae were analysed using light microscopy immunocytochemistry. They revealed severe lamellar edema, epithelial thickening, an increased number apoptotic crypt cells. Rodlet goblet cells also by 3.5- 2.5-fold, respectively, compared control collagen density lamina propria 1.7-fold. Cadmium upregulated metallothioneins PCNA-positive function was assessed through behavioural odour recognition test, followed recovery phase which zebrafish exposed placed clean six days. fish performed poorly, failing reach five consecutive trials. However, damage reduced after period, their performance improved, becoming comparable group. These results suggest that disrupts smell, possible exposure. This evidence sheds aspects animal survival often overlooked when assessing environmental pollution.

Cardiovascular diseases are a rampant public health threat. Environmental contaminants, such as Cadmium (Cd), toxic metal, have been linked to increased risk for cardiovascular diseases. Given that human exposure Cd is increasing overtime, there need develop new therapies ameliorate toxicity. Selenium (Se), an essential trace element, has proposed rescue the effects of toxicity, with mixed effects. Se's narrow therapeutic window necessitates precise dosing avoid Here, we assessed various waterborne and Se concentrations sequences on cardiac function using zebrafish (

Accumulation of heavy metals by plants can serve as a defence against herbivory. Herbivores, in turn, may avoid feeding on contaminated tissues. Such avoidance, however, hinge upon the specific conditions faced herbivores.

We show that individual females do not preferentially move to leaf tissues without cadmium, despite clear costs their performance.
