The primary influence of geography on species diversity is related to the variation in environmental conditions across different regions. Geographic features such as mountains, rivers, and climate zones create diverse habitats that support various life forms. Furthermore, the spatial distribution of ecosystems can lead to varying levels of isolation, promoting speciation and evolutionary adaptations among populations. Areas with more complex geographic structures often exhibit higher species richness. Thus, geography plays a key role in shaping biological diversity and influencing patterns of ecological distribution.
