Is salinity the main ecological factor that influences foliar nutrient resorption of desert plants in a hyper-arid environment?

Table 3 Covariations among element resorption efficiencies (RE)

Bivariate relationship	Community (n = 16)		Species (n = 21)		Species PIC (n = 20)
Bivariate relationship	r	p	r	p	r	p
NRE - PRE	0.63	< 0.01	0.83	< 0.01	0.90	< 0.01
NRE - KRE	−0.28	0.29	0.10	0.66	0.58	< 0.01
PRE - KRE	−0.08	0.76	−.026	0.25	0.71	< 0.01
NRE - NaRE	−0.19	0.48	−0.17	0.46	0.16	0.49
PRE - NaRE	− 0.58	0.02	− 0.41	0.06	−0.04	0.88
KRE - NaRE	− 0.02	0.95	−0.03	0.89	0.23	0.33

Significant relationships at p < 0.05 level are presented in bold (analyzed by Pearson correlation)
RE indicates resorption efficiency, PIC phylogenetically independent contrasts
