How do microclimates influence biodiversity in urban environments?

Urban areas are often perceived as concrete jungles with little room for biodiversity. However, microclimates, which are local atmospheric zones where the climate differs from the surrounding area, can create unique habitats even in densely populated cities. These microclimates are influenced by factors such as building materials, urban landscaping, and human activities. They can provide niches for various plants and animals that might otherwise struggle to survive in the broader urban environment. Understanding how microclimates contribute to urban biodiversity can help in designing more sustainable and diverse city landscapes. What are some examples of microclimates in cities, and how do they support biodiversity?
