Niche relationships between Betula platyphylla and main understory herbages in forest-steppe ecotone of Daxinganling Mountains

Abstract

Abstract: Niche breadths and overlaps for Betula platyphylla and other main herbaceous plant populations, and their changes along with three soil factor dimensions at three different altitudes were analyzed. The niche breadth of Carex pediformis increased with altitude, and that of other plant species was the widest on t he transect of middle altitude (800m) on the soil organic matter dimension, whil e the narrowest on the available phosphorus dimension. Niche overlaps of most sp ecies pairs on organic matter and available soil phosphorus dimension were the s mallest on the highest altitude (950mabstract On pH value dimension, niche overlaps of Iris sanguinea with most other plant species were the smallest on the lowes televation (650m) because of its probable niche shift forced by the special env ironmental complex of altitude. Most of the plant species pairs had the biggest niche overlaps on all the three dimensions on the transect of middle elevation.
