Fig. 2
The influence of spatial grain on diversity‒elevation relationships in Kenya’s montane ecosystems. The figure displays the variation in diversity‒elevation patterns across different spatial grains within montane ecosystems. The curves derived from local polynomial regression models illustrate the association between diversity and elevation without confidence intervals to facilitate easier visualization. The color gradient from yellow (0.0001 km2) to dark blue (10 km.2) represents the range of spatial grains used for sampling, following a strictly nested quadrat design.
