“…Therefore, the enriched δ 15 N values for larch seemed to be due mainly to preferential uptake of ammonium and physiological differences in transport, and assimilation of N between these species (Pardo et al 2006(Pardo et al , 2013, because leaf δ 15 N values in the present study agree with values found in larch forests of Mongolia (Hayashi et al 2018). Leaf δ 15 N in black locust and cedar were similar to tree-ring δ 15 N values of black locust (close to atmospheric δ 15 N = 0) and black pine in coastal areas (ranging from − 2.0 to − 4.0‰) of the Shonai Region (Lopez et al 2014), respectively.…”

“…The difference in the type of amino acid produced by each species could have influenced the N The online version is available at http://www.sprin gerli nk.com Corresponding editor: Yanbo Hu. mixed forests, tree species with lower NRE contribute more N in the leaf litter, which thus increases N availability in the soil (Lopez et al 2014;Chavez-Vergara et al 2015) and provides N to neighboring plants. Even though many studies have dealt with the process of resorption, very few studies have used isotope analysis to examine N isotope discrimination during this process (Kolb and Evans 2002;Templer et al 2007), especially in the context of the duration of resorption.…”

“…The trees are planted in order to enhance soil carbon content (Zeleznik and Skousen 1996, Khan et al 2010, Matos et al 2012. In plantations black locust may change the soil nutrient content (Landgraf et al 2005, Malcolm et al 2008) and even enhance the nitrogen status of neighboring trees (Lopez et al 2014). The additional nitrogen input into the ecosystem through the nitrogen fixation of black locust can be considerable with 48-86 kg N ha -1 a -1 (Rice et al 2004.…”

“…Nitrogen isotopes in tree-rings have been used in multiple coastal forest sites in Japan to evaluate the long-term effect of avian N deposition on soil fertilization [9,10,30] and nitrogen exchange between black pine and invasive leguminous species [31]. Based on the environmental disturbance caused by the tsunami and the consequent physiological response of trees, as inferred from isotope analysis, we have three hypotheses about the possible effects of the tsunami on pines: (I) Salt deposition in the soil has led to a decrease in tree growth driven by a decrease in stomatal conductance and photosynthetic rate.…”
