Flora mszaków i porostów Kanionu Colca (Peru) - badania rekonesansowe
(Wydawnictwa AGH, 2008) Cykowska, Beata; Flakus, Adam
The paper is a preliminary report of a long-term project that aims at completing the flora of bryophytes and lichens in the projected Canyon Colca and the Valley of the Volcanoes National Park area (Arequipa, Peru). The bryophytes and lichens of this deepest canyon in the world has remained underexplored for a long time. These organisms dominate in the vegetation cover and exhibit a remarkable species diversity resulting from habitat richness in this area. The important result of preliminary studies was discovered the first records of lichens Lecanora leuckertiana in South America and Lepraria impossibilis in the Southern Hemisphere. Further researeh should result in completing floristic lists of bryophytes and lichens of the Canyon Colca and the Valley of the Volcanoes National Park and should provide arguments for the protection of its unique wild life.

Wstępne opracowanie bioty porostowej w obrębie Kanionu Colca oraz Doliny Wulkanów (Peru)
(Wydawnictwa AGH, 2008) Sobiech-Matura, Katarzyna; Węgrzyn, Michał
Lichenological investigations were conducted in the region of Colca Valley, Colca Canyon and Valley of the Volcanoes (Central Andes), in the area of puna, at altitudes between 3000 and 5000 m a.s.l. Specimens were collected on 20 sites, located using GPS receiver. Most of the 150 specimens are crustose lichens. Squamulose, foliose and fruticose lichens are less frequent. Epilithic lichens belong mostly to genera Acarospora, Buellia and Psiloparmelia. Among epigeic lichens most common are species of following genera: Acarospora, Flavoparmelia, Lecidea, Caloplaca, Lepraria and Physconia. On wooden parts of cacti genera: Buellia, Caloplaca, Teloschistes and Xanthoria were identified, and on wooden parts of vascular plants genera: Physcia, Buellia, Candelariella, Usnea, Parmelia and Caloplaca. Now further work is being done to determine the species and the level of lichen biodiversity in this region.
