How can you account for the differences in the recapture numbers for polluted and non polluted sites?

Differences in recapture numbers between polluted and non-polluted sites can be attributed to several factors, including habitat quality, food availability, and stress levels experienced by organisms in polluted environments. Polluted sites may have reduced biodiversity and altered species interactions, leading to lower recapture rates. Additionally, pollutants can impair the health and reproductive success of organisms, resulting in decreased populations over time. Environmental disturbances and reduced survivorship in contaminated areas further contribute to these discrepancies in recapture numbers.
