Introduction Tropical rain forest – the most diverse ecosystem in the world Myers et al., 2010
3
Introduction Classification of organisms – taxonomical X functional
Functional traits - characteristics of an organism relevant to its response to the environment and its effects on ecosystem functioning „hard“ traits – growth… „soft“ traits – wood density, SLA, height…

Introduction (Pérez-Harguindeguy, 2014)
5
Introduction The aim of the study is to predict the growth of tropical trees on the basis of functional traits

Study site

Study site – permanent plots
2 plots (100 x 100 m) All trees (dbh > 5 cm) – xyz position, diameter in breast height, taxonomy, height (from 1991) 1 ha – 1318 trees, 47 families (Euphorbiaceae, Dipterocarpaceae, Myrtaceae) Digital terrain model of Plot 1 305 a s.l. 278 a s.l. Hédl et al., 2009 Hédl et al., 2009

Methodology – in the field
Collecting of wood samples - increment drill (Presslerův přírůstový nebozez) cm core
9
Methodology – in the field
Collecting of leaf samples - scissors, slingshots, climbing
10
Methodology – in the lab
Weighting, measuring, scanning, drying (Brunei) XEPOS analyzer, CHNS analyzer (Brno)
11
Methodology – traits Wood density Specific leaf area (SLA)
Leaf dry matter content (LDMC) Leaf thickness Content of N, C, H, P, K, Ca…
12
Methodology – chemical traits
Some elements maybe related with growth Element content will be used in a model with soil conditions, tree size, topography etc.
