Eksempler på lichen

• The vanishing tropical rain forest as an environment for bryophytes and lichens.

• An overview on lichenological investigations gives the background of the history of research on lichens since 1820.

• The symbiotic state enables the lichen thallus to colonize extreme habitats where the separate bionts would not be able to survive.

• Channel-imaging was correlated with contour images to improve recognition of visual damage, which reflects the vitality of the lichen tissue.

• The results presented here emphasize the fact that lichen symbiosis shows an extremely high resistance to the simulated extreme space conditions used in our experiments.

• The ability to map the distribution of lichens is more open to question.

• The whole lichen thallus appears to be vital.

• Maximum diameters of a crustose lichen mean that many small areoles or lobules form a conglomerate of thalli.

• Lichen from the breccia outcrop was analysed for reference.

• Furthermore, as a result of these uprated properties, the lichen is highly desiccationtolerant, which is a prerequisite for its occurring above ground.

• Reproductive strategies, relichenization, and thallus development observed in situ in leaf-dwelling lichen communities.

• A remote sensing methodology for monitoring lichen cover.

• Ever since terrestrial biology became a significant field of research, a detailed monography on lichens has been missing.

• The exposed bacteria and lichens were accommodated in specially designed anthropogenic hardware manufactured to endure the space environment.

• Mosses and lichens occur in the vicinity of small ephemeral watercourses.
