Assertion: Colombia located near the equator has nearly 1400 species of birds which New York $41^{\circ} \mathrm{N}$ has 105 species and green land at $71^{\circ} \mathrm{N}$ only 56 species. Reason: Generally tropics harbour more species than temperate or polar region.

Key Concepts

Latitudinal Biodiversity Gradient

This concept refers to the pattern observed in nature where species diversity tends to be highest in tropical regions near the equator and decreases towards the poles. It is a key observation in biogeography that helps explain why regions with warmer and more stable climates during the year support a greater number of species compared to colder, more seasonal regions.

Biogeography

Biogeography is the study of the distribution of species and ecosystems in geographic space and through geological time. It examines how ecological, climatic, historical, and evolutionary factors influence the patterns of species diversity and distribution across different regions of the world.

Species Richness

Species richness is a measure of the number of different species represented in an ecological community, landscape or region. It is an important aspect of biodiversity and helps scientists understand the health, resilience, and functioning of an ecosystem, often showing variation according to environmental factors such as climate and latitude.
