Alexander von Humboldt showed that species richness increases with explored area, and on a logarithmic scale the relationship becomes a straight line (log S = log C + Z log A).

Paul Ehrlich's rivet popper hypothesis explains that gradual loss of species weakens ecosystem functioning, much like removing rivets weakens an aircraft.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Species richness is highest in tropical regions and generally decreases towards the poles.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Species richness is highest in the tropics and generally decreases towards the poles.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Species richness is highest in tropical regions because they have experienced long evolutionary periods under relatively stable environmental conditions.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Species richness is highest in tropical regions and decreases towards the poles. It is not uniform across all regions.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
According to NCERT, species richness is highest in tropical regions because of their long evolutionary history, relatively stable environment, and greater availability of solar energy.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
NCERT attributes the high biodiversity of tropical regions to their long evolutionary history, relatively stable climate, and greater availability of solar energy.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Patterns of Biodiversity - Latitudinal Gradients
Species richness increases from higher latitudes towards the equator. This pattern is known as the latitudinal diversity gradient.

Tropical rainforests possess exceptionally high species richness and are expected to contain many undescribed species.

Biodiversity hotspots are regions rich in endemic species that face a high degree of habitat loss and therefore require priority conservation.
Ref: NCERT Class 12 Biology Chapter 13: Biodiversity and Conservation Biodiversity - Levels - Genetic Species Ecological
“Immigration rate” for increase in island distance primarily affects. This relationship follows from the ecological mechanism represented by the terms in the item, not merely from an association between their names. Larger islands usually support more habitats and larger populations, lowering extinction risk; less isolated islands receive colonists more readily and may experience rescue effects. These mechanisms also apply to habitat fragments that function as ecological islands. The remaining alternatives—“Extinction rate”, “Resource availability”, “Genetic drift”—refer to different states, p
