Résumé : |
This thesis examines patterns in bryophyte species richness and composition on the forest floor and in the soil diaspore bank of temperate rainforest stands which varied in time post-harvest. Quantitative data (abundance) was assessed in quadrats (25x25cm) on soil, decaying logs, and tree bases within sites (20x30m). Non-quantitative data (occurrence) was assessed throughout sites. Analyses of variance and ordination analyses were used to examine species richness and composition, respectively.
Above-ground, richness varied significantly with substrate but not stand age. Soils were the most speciose substrates, due to heterogeneity in young stands; logs had higher richness in older stands. Canopy cover significantly affected species composition, with a trend in dominant life strategy from colonists to perennials with canopy closure. Below-ground, richness varied significantly with depth but not with stand age. Diaspore bank richness and composition differed from the above-ground flora; colonists dominated the diaspore bank and perennials thrived above-ground. |
