Innes J. L. (1985): Replication of lichenometric data: errors associated with variations in operator search efficiency - Area, 17: 221-232

The reproducibility oflichen measurements is poor. Errors may arisefrom mismeasurement ofindividual lichen thalli or from failing to locate large thalli. Observers obtained much more consistent results when a quadrat search was repeated. The reproducibility ofRhizocarpon section Rhizocarpon species measurements increases with increasing sample size but the reverse occursfor Rhizocarpon alpicola measurements. Variations in the extent of error occur between different quadrats, but these appear to be … Read more...

Innes J.L. (1986): Dating Exposed Rock Surfaces in the Arctic by Lichenometry: The Problem of Thallus Circularity and Its Efect on Measurement Errors - Arctic, 39(3): 253-259

Lichenometry represents an extremely useful dating technique in the Arctic. It is most appropriate for exposed rock surfaces, which are abundant in most arctic environments, and on occasion it represents the only suitable technique for estimating the age of a surface. As a result, Iichenometry is being used in an increasing number of arctic studies. Despite this, controversy still surrounds the manner in which individual thalli are measured. The majority of workers measure either the longest axis … Read more...

Innes J.L. (1985): An examination of some factors affecting the largest lichens on a substrate - Arctic and Alpine research, 17(1): 99-106

The ecological basis for using the mean of the five largest lichens in lichenometry has been examined by investigating the Rhizocarpon section Rhizocarpon species growing on gravestones in Highland Scotland. The ratio of the mean of the five largest thalli to the single largest thallus on a substrate provides an index of the lichen performance on each stone which can then be related to environmental and temporal factors. Ratios appear to be unaffected by substrate lithology and orientation. but respond … Read more...

Innes J.L. (1984): The optimal sample size in lichenometric studies - Arctic and Alpine research, 16(2): 233-244

Lichens growing on moraines at Storbreen and Nigardsbreen, southwest Norway, were investigated. The mean of the five largest thalli is the optimum lichenometric index of the lichens growing in a quadrat of a given size. The variability of this index is closely related to the size of the quadrat, and decreases with increasing sampling area. Rhizocarpon alpicola is much more variable than species within the Section Rhizocarpon, although this may be due to the relatively young R. alpicola populations … Read more...
