Plant nutrient‐acquisition strategies contribute to species replacement during primary succession

open access: yesJournal of Ecology, Volume 113, Issue 4, Page 988-1003, April 2025.
Pioneer species Hippophae acquires phosphorus and nitrogen mainly by ‘mining’ and N2‐fixing strategies and thus dominates in the beginning of primary succession. As soil nutrient availability increases with the mobilization of apatite‐P and input of N‐rich plant residues, Hippophae' strategies become less efficient than Populus's scavenging strategies.
