Kärnefelt I. (2003): Three species of Caloplaca in Australia with different reproductive models, Bibl. Lichenol., 86: 341-350

The distribution of Caloplaca bassiae, C. cimabarina and C. cupulifera occurring ||me Australian continent is discussed. These species have different ways of reproduction Ijifisidia, soredia or with ascospores. The fertile species, Caloplaca cimabarina, is the Öst widely spread. Distribution maps for Australia and the world are provided Read more...

Feuerer T., Hertel H. & Deuter H. (2003): The corticolous and lignicolous lichens of Munich (Germany) - a preliminary evaluation, Bibl. Lichenol., 86: 329-339

226 species of epiphytic lichens are listed for the city of Munich, 102 of these could not be found anymore since the 19th century, and are classified here as regionally extinct. 19 species are listed for the first time for the city. 80 % of the actual flora is threatened in different stages of intensity, some of these species are represented by one single specimen Read more...

Tretiach M., Crisafulli P., Virgilio D., Baruffo L. & Jensen M. (2003): Seasonal variation of photoinhibition in an epiphytic population of the lichen Parmelia sulcata, Bibl. Lichenol., 86: 313-327

Experimental samples of Parmeiia sulcata collected every two months in a dense deciduous forest of Mt. Amiata (Tuscany, Central Italy) were exposed to three different light regimes (50, 175 and 350 pmol photons m'2 s'1) up to 5 hours to detect possible seasonal differences in their light response. Samples collected from June to October under the tree canopy |howed strong photoinhibition already at intermediate light conditions. In December, more than one month after litter fall, only a slight, reversible … Read more...

Sancho L.G., Pintado A., Green T.G.A., Pannewitz S. & Schroeter B. (2003): Photosynthetic and morphological variation within and among populations of the Antarctic lichen Umbilicaria aprina: implications of the thallus size, Bibl. Lichenol., 86: 299-311

Umbilicaria aprina is one of the few macrolichens which successfully grows at high latitudes in the continental Antarctic. In the Granite Harbour region (Ross Sea, southern Victoria Land, 77°00’ S) U. aprina commonly occurs over a broad environmental range. It grows in melt water channels as well as on dry rocks, in dark well-protected sites and in open areas. Differences in thallus colour appear to be related to the ecology. Whitish grey thalli are usually found in water channels, while blackish-grey … Read more...

Pannewitz S., Schroeter B., Scheidegger C. & Kappen L. (2003): Habitat selection and light conditions: a field study with Lobaria pulmonaria, Bibl. Lichenol., 86: 281-297

The shade-adapted Lobaria pulmonaria was found to be sensitive to modifications of the light regime in the forest. A comparison of thallus characteristics and of the photosynthetic performance of thalli from two different habitats in Switzerland revealed some adaptive and adjustive responses to different light conditions. Although the thalli in the open habitat were larger and had a thicker cortex than those from the dark-shaded habitat, the photosynthetic performance was not different between the … Read more...

Lange O. L., Green T. G. A. (2003): Photosynthetic performance of a foliose lichen of biological soil-crust communities: long-term monitoring of the CO2 exchange of Cladonia convoluta under temperate habitat conditions, Bibl. Lichenol., 86: 257-280

The CO2 exchange and microclimate of Cladonia convoluta were continuously monitored in a quasi-natural terrestrial habitat at the Botanical Garden Wurzburg (Bavaria, Germany). The performance of the lichen was characterised by analysis of more than 100 daily courses spread over all the seasons of the year. Interpretation of the field responses was made using the results of experiments on hydration dependency of thallus photosynthesis conducted under laboratory conditions. The results for the Cladonia … Read more...

Garty J. (2003): About the applicability of the lichen Ramalina maciformis (lichenized Ascomycetes, Ramalinaceae) as a biomonitor of air pollution in the Negev Desert, Israel, Bibl. Lichenol., 86: 243-255

Abstract: Two series of transplantation-experiments were designed to investigate the applicability of the lichen Ramalin amacifonnisas a biomonitor of air pollution in the Negev Desert, Israel. Thalli of R. macifonnis from the unpolluted Tellalim site were collected in August 1997 and May 1999 and transferred to biomonitoring sites in and around the industrial area of Ramat Hovav. The first batch of lichens was exposed in 24 sites and retrieved in August 1998. The second, exposed in 10 sites in and … Read more...

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...
