Abstract

Functional groups are defined as groups of species exhibiting similar responses to environmental variables. The aim of this study was to investigate the responses of plant functional groups to some environmental variables in Mountain forests of southern Zagros (Khuzsetan province, Baghmalek). Vegetation was sampled in 50 circular plots of 1000 m2 selective-randomly along an Elevational gradient from 646 to 3172 m a. s. l. Plant species were categorized in terms of Growth form to three functional groups including woody (tree and shrub), herbs, and woody sapling (tree and shrub sapling). Environmental factors (topographic and soil variables) were sampled per plots. Changes of the functional groups was analyzed in relation to environmental variables using Canonical Correspondence Analysis. The results showed that all three functional groups in the study area were significantly correlated to Elevation, followed by soil electrical conductivity, available potassium and pH. Besides, some groups were correlated particularly to soil variables. Woody species showed a correlation with microbial biomass carbon, clay percentage, aspect, organic matter content, sand, slope and total nitrogen. Herbs showed a correlation with soil organic matter, available phosphor, total nitrogen, sand, clay, basal respiration, bulk density and slope, while woody sapling showed strong relationship with aspect, total nitrogen, sand, slope, microbial biomass carbon and clay. Species Diversity of woody species increased toward higher altitudes while herbs decreased toward higher altitudes. Saplings expressed maximum Diversity at intermediate Elevations
