Nutrient content in leaves from different strata of a swamp forest from northern Turkey

Specific leaf mass (SLM), mass (mg/g) and area (g/m^2)-based nitrogen and phosphorus contents of plant species from different strata in a swamp forest (Pterocaryo fraxinfoliae-Fraxinetum angustifoliae) from the north part of Turkey were investigated. Leaf N/area (g/m^2) and leaf N/mass (mg/g) values differed significantly between small trees, large shrubs, small shrubs and climbers. Large shrub stratum has remarkably higher nutrient contents than the other strata. Leaf P/area (g/m^2) and leaf P/mass (mg/g) values were similar for the different strata.
