The high diversity of epiphytes typical of undisturbed montane tropical forests has been negatively affected by continuous deforestation and forest conversion to secondary vegetation. Macrolichens are an important component of these epiphytes. Because their physiology is strongly coupled to humidity and solar radiation, we hypothesized that microclimatic changes derived from forest clearing and...

The number of Fungi is estimated at between 1.5 and 3 million. Lichenized species are thought to make up a comparatively small portion of this figure, with unrecognized species richness hidden among little-studied, tropical microlichens. Recent findings, however, suggest that some macrolichens contain a large number of unrecognized taxa, increasing known species richness by an order of magnitud...

introduction: α-amylase is a major form of amylase found in humans and other mammals. it is the special key enzyme involved in carbohydrates breakdown. inhibition of this enzyme could be used in treatment of diabetes. in this study, the effect of ten iranian macrolichens on alpha amylase were tested. methods: different concentrations of the extracts (25, 50 and 75 mg/ml) were incubated with enz...

A floristic and ecological study of bryophytes and macrolichens in different lowland rain forest types around Mabura Hill, Guyana, South America, yielded 170 species: 52 mosses, 82 liverworts and 36 macrolichens. Lejeuneaceae account for about 30% of the species and are the dominant cryptogamic family of the lowland rain forest. Special attention was paid to the flora of the forest canopy, by u...

Abstract A study of the macrolichens diversity from Chaco National Park was conducted. Thirty-six species were identified, three which are recorded for first time Argentina (Dirinaria melanocapa, Pyxine petricola var. convexula, and P. pungens). Moreover, distribution 27 in country is extended, including new records province and, additionally, other provinces region. An identification key here ...

Lichens have a vital role in forest ecosystems and they are threatened group boreal forests. However, the conservation ecology of total lichen community has very rarely been studied. Here we studied species communities, including macrolichens (=foliose fruticose growth forms) crustose lichens, on decaying wood spruce-dominated forests Finland. We also obligate lignicoles that grow only dead mos...
