Threatened species richness along a Himalayan elevational gradient: quantifying the influences of human population density, range size, and geometric constraints

Table 4 Results of analysis of deviance (ANODEV) of generalized linear model with residuals regressed against altitude

	Df	Deviance	Residual Df	Residual deviance	F value	P value
Null	1		34	16.451
Poly (elevation, 3)	3	4.511	31	11.940	3.904	0.017

Residuals were obtained after removing effect of area and mid-domain effect in the model. Function “poly” represents a cubic transformation of the explanatory variable. This function also contains both linear and polynomial effects
