Zusätzliche Informationen: Original data: FOR402 (Phase 2) ID: 50705, 50707; Creator: Motzer, Thomas (AG: B 6 - B 6) This dataset has been migrated from the previous FOR402-Database to the FOR816-Database by the Central Data Management Z1/FOR816. Please keep in mind that the migration included all avilable metainfomation which were accessible through the FOR402-Database. Nevertheless, it can't be guaranteed that no thematic misinterpretation occured in the data/attribute description. There has been no further disciplin specfic control. In any case of ambiguity please contact the dataset creator.

C/N ratio in understory leaves

Dataset ID:	1494
Last updated:	2016-08-16
Ersteller:	Christine Wallis Stefanie Batke
Kontakt:	Stefanie Batke Yvonne Tiede Christine Wallis
Zeitliche Abdeckung:	2014-10-25 00:00:00 - 2014-12-17 00:00:00 - time zone: -5
Geographische Verortung:	South Ecuador

Abstract: For the determination of the C/N ratio in leaves of understory plants we collected representatively leaves from 27 plots in natural and disturbed forest sites (1000 to 3000 m a.s.l.) in the dry season in 2014. We considered the shrub layer and the herbal layer of 30 randomly chosen m2 per plot. The collected leaves were dried and prepared to determine the C/N ratio with a C/N Analysator (Vario EL III).

Abstract: We measured LAL (leaf area loss) as an indicator for herbivory for 27 plots in natural and disturbed forest sites (1000 to 3000m a.s.l.). LAL (%) was estimated for the shrub layer and the herbal layer in 30 randomly chosen m² per plot. We averaged the LAL of both layers.
