摘要：

Growth curves for Rhizocarpon subgenus Rhizocarpon and Pseudephebe minuscula were constructed by measuring lichens on deposits of known age spanning the last 350 yr. The Rhizocarpon curve comprises a fast-growing great growth period (21 mm 100 yr-1) lasting c100 yr and a slower-growing phase (4.5 mm 100 yr-1) between 100-350 yr. The P. minuscula curve is constrained for the last 80 yr but senescence and rejuvenation of P. minuscula thalli on whaling features of the 17th century preclude form control beyond 80 yr. -from Author
