TI  - Annual N and P nutrient levels and foliar resorption in Alnus glutinosa subsp. glutinosa (Betulaceae) leaves
AB  - Alnus glutinosa (Betulaceae) has a widespread distribution in the Central Black Sea Region of Turkey. In this study, annual nitrogen (N) and phosphorus (P) dynamics and foliar resorption efficiency and proficiency were investigated in A. glutinosa. N and P concentrations were decreased in senescent leaves. Statistically significant differences were found in P concentrations while there were no found significant differences in N concentrations with respect to months. A negative correlation was obtained between SLA and LMA, SLA and N concentrations. However, there were significant correlations between LMA and N concentrations. N and P resorption efficiency (NRE, PRE) and proficiency (NRP, PRP) values were high as compared to the other deciduous species. These results indicate efficient internal cycling of nutrients especially P in A. glutinosa.
