Seasonal growth and growth rate-colony size relationships in six species of saxicolous lichens -
New Phytologist,
72(5): 1023–1030
The pattern of seasonal growth and the relation of growth rate to colony size were studied in four foliose and two crustose species of saxicolous lichens. A new method of measuring growth was used whereby the advance of a sample of lobes along millimetres marked on the substrate was measured under a magnification of × 10. Three peaks of growth were found (in March, June and November) for the foliose species and a single peak (in May–August) for the crustose species. The peaks of growth corresponded …
