Abstract:
Master-thesis: “Influence of diversity on N-distribution in canopy’s from subtropical trees in China”
Design:
Leaf samples were taken from four trees per species per VIP-plot for each diversity level (1-16) via secateurs or glasfiber telescopic poles. In each crown the leaves were taken in three layers (under/mid/top) for each cardinal direction (12 leaves per tree). Samples from the same layer and same individual were pooled for C/N-analyses.
Spatial extent:
Main experiment, Site A 29°08'-29°11'N
117°90'-117°93'E Vip, Viprep, plots of site A
Temporal extent:
May 2014 - July 2014
Taxonomic extent:
C.axillaris, C.eyrei, C.glauca, C.henryi, C.myrsinaefolia, C.sclerophylla, K.bipinnata, L.formosana, L.glaber, N.sinensis, Q.fabri, Q.serrata, R.chinensis, S.mukorossi S.sebiferum , S.superba
Measurement cirumstances:
hot and many moscitos
Data analysis:
Chlorophyl meassured with CCM-300; Leaf area was determined by scans which were calculated by WINFOLIA; Carbon & Nitrogen (C,N) content of leaf material measured by elementar analyser
