This study was conducted to identify and classify the lichens; determine the diversity index and richness of lichens. A total of 36 species belonging to six genera under three families was identified. Lichen species were mostly found at moderate high altitudinal range with an elevation of 1,131 meters above sea level and open areas where they received adequate sunlight with high moisture and hu...

In this study, host plant - lichen specificity was investigated. Data collected from 1000m2 sampling plots at each of four locations with an established 50m x 20m plot site. Forty-one trees across five species were examined using (10cm by 50cm) ladder quadrats on tree trunks (N, S, E, W) 150cm height. A total 14978 individual lichens identified that yielded 10 families, 13 genera and 18 species...

Crustose corallines, crustose and erect brown algae, and sessile animals are major components of the epiphytic community of the Mediterranean seagrass Posidonia oceanica (L.) Delile. Production, biomass, and specific composition of this epiphyte-seagrass association are impacted by anthropogenic increase of nutrient load in this oligotrophic area. In this context, nitrogen uptake by P. oceanica...

IntroductIon The family Hymeneliaceae is a small group of lichens, characterised chiefly by a crustose thallus containing a green photobiont (either trebouxioid or Trentepohlia), usually aspicilioid apothecia immersed in the thallus surface, and mostly weakly amyloid or non-amyloid asci containing eight, simple, colourless ascospores. Many species have an attractive, bright orange thallus. The ...

This paper presents a system for modeling lichens and simulating their propagation and growth in a virtual scene. Lichens colonize almost every substrate in nature and play an important role in the visual appearance of a natural object. The propagation of lichens over the substrate is performed by an Open Diffusion Limited Aggregation model constrained by the characteristics of the environment....

Four different methods of epiphytic lichen mapping were used for the assessment of air quality in the region under the influence of the Sostanj Thermal Power Plant (Salek Valley, Slovenia). Three methods were based on the presence of different lichen species (VDI, EU and ICP-Forest), the fourth on a frequency and coverage assessment of different growth forms of epiphytic lichens, e.g. crustose,...

The new combination Stereocaulon plicatile (Leight.) Fryday & Coppins is made for a previously enigmatic crustose lichen with submuriform ascospores; the basionym, Lecidea plicatilis Leight., was previously misapplied to a norsticticacid containing species of Rhizocarpon. The systematic position of the crustose Stereocaulon leucophaeopsis group is discussed. ? 1996 The British Lichen Society
