क्यों और कैसे होता है

कारण और संदर्भ

Biodiversity is the variety of life at genetic, species and ecosystem levels. The governing relationship is: Evolution, habitat diversity, isolation, disturbance and human pressure shape biodiversity across space and time.

यह कैसे काम करता है

Evolution, habitat diversity, isolation, disturbance and human pressure shape biodiversity across space and time.

मुख्य तथ्य

• Genetic diversity supports adaptation within species.
• Species richness counts species; evenness describes relative abundance.
• Habitat loss, invasive species, overexploitation, pollution and climate change are major threats.

ज़रूरी शब्द

• species richness
• genetic diversity
• endemism
• invasive species
• ecosystem diversity

आम गलतफ़हमियाँ

• Biodiversity is broader than the number of species.
• An exotic species is not automatically invasive; invasion requires harmful establishment and spread.
