Prügger J., Mayrhofer H. & Grube M. (2003): The on-line database of Slovenian lichens, Bibliotheca Lichenologica, 86: 407-416

An on-line database, named SLIC (Slovenian lichen information console), is presented for lichens in Slovenia. The database is implemented using the Oracle 8 database managementDown known distribution of lichens in Slovenia is available. The database consists of the specimen data used to generate the recently published catalogue of Slovenian lichens. A thesaurus is included for historic names often found on old herbarium labels. The locality data can be retrieved as full text or as Gauss-Krueger coordinates, … Read more...

Kricke R. (2003): Modellvorschlag zum Verlauf der Wiederbesiedelung ehemals flechtenfreier Räume, Bibl. Lichenol., 86: 381-392

Wegen der allgemein gesunkenen Immissionsbelastung ist vielerorts eine Wiedereinwanderung epiphytischer Flechten in solche Gebiete zu verzeichnen, die ehemals flechtenfrei oder in ihrem Flechtenbewuchs stark dezimiert waren. Anhand von Literaturdaten sowie eigenen Untersuchungen im Ruhrgebiet werden allgemeine Vorgänge im Rahmen der Wiederbesiedelung aufgezeigt, und es wird ein Modell vorgestellt, das den Wiederbesiedlungsprozess zeitlich gliedert und somit Prognosemöglichkeiten für Gebiete bereil- … Read more...

Krain V., Daniëls F. J. A. (2003): A comparative study of the lichen floras of calcareous substrata in graveyards with natural limestone rocks in north-eastern Sauerland, Germany, Bibl. Lichenol., 86: 369-379

The lichen floras on 16 exposed limestone rocks (Massenkalk) and stony calcareous substrata in 31 graveyards were studied in north-eastern Sauerland, Germany. A new system of functional lichen types for calcareous epilithic lichens was developed which is based on reproduction modes and growth form characters. The differences in lichen flora and functional lichen types between the two habitat types are presented and discussed in an ecological context. In all. 116 lichen species were found, with 100 … Read more...

Komposch H. & Hafellner J. (2003): Species composition of lichen dominated corticolous communities: a lowland rain forest canopy compared to an adjacent shrubland in Venezuela, Bibliotheca Lichenologica, 86: 351–367

Cryptogamic epiphytes that inhabit rain forest canopies are known to be also represented in canopies of secondary and more open forest and savanna types. In order to get information about this so called ‘canopy effect', lichen dominated communities were investigated in the canopy of a lowland rain forest and on scattered shrubs in a rocky shrubland near La Esmeralda village in southern Venezuela. Transparencies were pinned to the phoro- phytes to estimate the perimeter of cryptogams. The area of … Read more...

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...
