Exploring why some animals thrive in cities, researchers analyze factors such as diet, body size, mobility, and reproductive strategies globally. Birds, reptiles, and amphibians adapt in urban environments, emphasizing urban biodiversity. The symbiotic relationship between diverse animal life in cities manages carbon emissions and promotes biodiversity for a sustainable cityscape.
Urban animals utilize different survival strategies: generalists adapt through flexibility, while specialists focus on specific diets.
Maintaining urban biodiversity has environmental and health benefits, including climate change mitigation and disease prevention.

Different Strategies for Urban Animal Survival
Animals in cities adopt varied strategies for survival. Mobile generalists like urban bats and beetles thrive on flexibility, moving across large areas and having a broad diet. On the other hand, urban birds and bees succeed as central place foragers, nesting in fixed locations while diversifying their diets. Site specialists such as reptiles and amphibians adapt by specializing their diets, moving in smaller areas, and having fewer offsprings to cope with urban challenges.
Global Study on Urban Animal Traits
Research encompassed data from 5,302 species in 379 cities worldwide to understand how animals adapt to urban environments. The study explored traits such as diet, body size, mobility, and reproductive strategy across different species. It revealed that flexibility is valuable, but animals also succeed through strategies like central place foraging and specialization, showcasing diverse responses to urbanization.
Significance of Urban Biodiversity
Maintaining urban biodiversity offers various benefits, including mitigating climate change impacts and enhancing ecosystem services. Greater biodiversity in cities supports healthy soil, reduces flooding risks, and aids carbon sequestration. Diverse urban ecosystems also regulate disease-carrying insect populations, contributing to human health protection. Investing in green infrastructure and urban forests can improve urban biodiversity, fostering sustainable and resilient urban areas.
