Ecological Solutions and Evidence, Volume 6, Issue 3, July–September 2025.Urban agriculture is in an intermediate state between traditional urban green spaces and conventional rural farms in terms of environmental impacts, so that its contribution to urban sustainability requires complementarity with other green spaces. Abstract As cities expand, they encroach on agricultural land, impacting food production and natural ...

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