John A.E. (1988): An assesment of the role of biotic interactions and dynamic processes in the organization of species in a saxicolous lichen community - Can. J. Bot., 67: 2025-2037

A saxicolous lichen community is examined for evidence of dynamic processes and biotic interactions among its members. Spatial relationships among species are examined in a series of association analyses at three scales: (i) the "nearestneighbour" scale, i.e., associations between touching thalli; (H) associations between thalli 10 and 20 cm apart; and (Ui) associations at the scale of the whole rock face. The nearest-neighbour analysis reveals fundamental differences in the way crustose and foliose … Read more...

John A.E. (1989): Note on the sizes of largest thalli of three species of Rhizocarpon (subgenus Rhizocarpon) at a rockslide in the Canadian Rocky mountains - Arctic and Alpine Research, 21(2): 185-187

The largest thallus sizes of three species of Rhizocarpon (subgenus Rhizocarponi growing at a single site are significantly different. In addition, each species appears to respond differently to local changes in microclimate. Jonas Rockslide, Alberta, Canada, is estimated to be at least 500 yr old, rather than the 100 yr old suggested by other researchers Read more...

Jahns H.M. & Smittenberg J.C. (1970): Baeomyces roseus Pers., Ontogenie und Regeneration der Fruchtkörper - Herzogia, 2: 79-88

The ontogeny of the fruiting bodies of Baeomyces roseus is investigated and compared to that of Baeomyces rufus. Baeomyces roseus has ascogons with trichogynes similar to those of Baeomyces rufus. In Baeomyces roseus an apothecium is formed on the surface of the thallus horizontalis. Later it is lifted upwards by the podetium. In Baeomyces rufus the podetium arrises prior to the forming of the apothecium. Therefore the genus should be divided into two subgenera - subg. Baeomyces (with B. roseus) … Read more...

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...
