Davis W.C., Gries C. & Nash III T.H. (2003): The influence of temperature on the weight and net photosynthesis of the aquatic lichen Peltigera hydrothyria over long periods of time, Bibliotheca Lichenologica, 86: 233-242

This study reports the change in weight and the net photosynthetic response of the aquatic lichen Peltigera hydrothyria across long-term incubations of water temperatures from 5 - 30°C, from periods of hours to months. At a temperature of 5°C there was little change in weight or net photosynthetic response for periods as long as 400 days. At a temperature of 11°C, a decline in net photosynthetic response was apparent after 150 days; at 15°C, after 120 days; at 18°C, in 30 days. At 21°C net … Read more...

Büdel B. & Schultz M. (2003): A way to cope with high irradiance and drought: inverted morphology of a new cyanobacterial lichen, Peltula inversa sp. nova, from the Nama Karoo, Namibia, Bibliotheca Lichenologica, 86: 225-232

A new cyanobacterial lichen species, Peltula inversa (Lichinales, Peltulaceae), growing on the lower part of quartz pebbles, where they contact the surrounding soil (= hypolithic), is described here. The internal morphology of the new species is inverse, exposing the cyanobiont layer towards the translucent quartz rock. Only a very small part of the thallus is exposed to the soil surface and then black-olive colored. When seen from above, sterile and fertile parts of the thallus surround the … Read more...

Ascaso C., Souza-Egipsy V., Sancho L. G. (2003): Locating water in the dehydrated thallus of lichens from extreme microhabitats (Antarctica), Bibl. Lichenol., 86: 215-223

Microbial ecology deals with interactions among microorganisms, between microorganisms and their environment, and with water relations in the microhabitat. In the desiccated state, many lichens tolerate long periods of intense stress. The present report describes the use of scanning electron microscopy with backscattered electron imaging (SEM-BSE) to observe - on the spatial nanometer scale - relationships among the epilithic thallus of an Antarctic lichen, microorganisms belonging to epilithic, … Read more...

Herk van C. M. & Aptroot A. (2003): A new status for the Western European taxa of the Cladonia cervicornis group, Bibl. Lichenol., 86: 193-203

Within Cladonia cervicornis, currently three taxa are accepted in western Europe, viz. ssp. cervicornis, ssp. verticillata and ssp. pulvinata. Co-occurrences of two or even all three taxa are quite frequent and have been observed by the authors in the field in numerous localities in the Netherlands as well as other European countries. We tested the hypothesis that all three taxa can be recognized at species level. Even in mosaics, single thalli of ssp. cervicornis and ssp. verticillata could be determined … Read more...
