Zedda, L; Gröngröft, A; Schultz, M; Petersen, A; Mills, A; Rambold, G: Distribution patterns of soil lichens across different biomes of southern Africa, Journal of Arid Environments, 75(2), 215–220 (2011), doi:DOI:10.1016/j.jaridenv.2010.10.007
Abstract:
The present study was undertaken to assess baseline distribution patterns for soil lichens occurring in the principal biomes of southern Africa, and to analyse their relationship to selected environmental parameters. Among the lichen species found across our survey sites, four distinct groups could be delineated, each as distinct consortium of lichen species sharing particular morphological characters (e.g. growth-form, pigmentation and type of photobiont kind). These groups are largely correlated with specific environmental parameters. These findings suggest that lichens may serve as valuable bioindicators for evaluating climate and soil change in this region of Africa.
