Role of Polychlorinated Biphenyls (PCBs) and Polycyclic Aromatic Hydrocarbons (PAHs) on Survival of Free Ranging Birds: A Review
Abstract: The PCB contaminant levels reported in tissues individuals are not likely to have an impact on the demographic performance of the birds as a whole. However, the residues may reach levels causing decreased reproduction or survival in some years, particularly when combined with other non-anthropogenic stressors such as food scarcity. In addition, the birds normally would have more exposure to the contaminants due to their position in the food chain. …

Assessment of Exposure to and Effect of Organochlorine Pesticides on Birds in India
Abstract: Effects of pesticides on birds have been well documented in many European and North American countries. Although we have some information on the levels of persistent environmental contaminants in many species of birds in India, due to lack of adequate data, we are unable to make any direct correlation with the reported population decline. Of all the birds, levels of DDT, HCH and dieldrin recorded in some of the species …

Acetylcholinesterase and Butyrylcholinesterase Activities in Brain and Plasma of Several Species of Birds in India
Abstract: Since timely acquisition of concurrent controls is not always feasible, development of a reference data of normal cholinesterase (ChE) activities for various wildlife species particularly for birds is necessary to diagnose anticholinesterase exposure. In the present study, acetylcholinesterase (AChE) and butyrylcholinesterase (BChE) activities in brain and plasma of several species of birds collected from Ahmedabad, India, during 2005–2007, were determined. Brain AChE activity ranged from 1.24 µmole/min/g in Indian white-backed …

Strategies to Minimize Heat Stress in Broiler and Layer Chickens
Abstract: Heat stress is one of the most important thermal environmental factors challenging broiler and layer production throughout world. Negative effects of heat stress on broilers and layer production range from reduced growth and egg production to reduced egg quality. Heat stress is more in chickens with high production performance and more feed conversion efficiency. Prolonged exposure to hot weather will lead to imbalance of acid-base equilibrium in body, decreases blood …

Environmental Pollutants and Biodiversity Loss: Analyzing the Role of Persistent Organic Pollutants in Ecosystem Decline
Abstract: Persistent Organic Pollutants (POPs) significantly impact biodiversity, with various factors influencing their effects on species and ecosystems. Species in poor body condition, like carnivores and predators, are more vulnerable to POPs due to weakened immune systems and reduced detoxification abilities. Dietary habits also affect the accumulation of POPs, as chemicals biomagnify up the food chain. Carnivores accumulate higher concentrations, leading to reproductive failures, hormonal imbalances, and death, while herbivores face …
