Fig. 5: The effect of the size of the protected area on the loss of forest biomass, species richness, and species properties.

From: The erosion of biodiversity and biomass in the Atlantic Forest biodiversity hotspot

Fig. 5

For each survey (points), panels present the indices of loss of a forest biomass (n = 555 surveys); b tree species richness (n = 617 surveys); c weighted average species property loss; d wood density; e maximum height; f seed mass; g ecological groups; h threat of extinction; and i endemism level. The summary of the linear or of the piecewise regression models is given in the top of each panel, along with the adjusted R2 of the model, its summary F-statistics and the associated p-value (one-sided statistical test). Degrees of freedom for the regression models are: panel a = 554, panel b = 616, panels ch = 364. The vertical dashed line is the estimated break-point of the piecewise model, which is plotted only for the variables were this model had a better performance than the linear model. The standardized index of loss is dimensionless and is highlighted by different colours ranging from dark red (high losses) to blue (gains).
