Abstract Background and aims Low productivity open lichen ( Cladonia spp.) woodlands have been rapidly expanding in the closed-crown feather moss Pleurozium schreberi (Brid.) Mitt.) boreal forest of eastern Canada. While open-woodland areas are progressing, there is little information on recoverability back to closed-canopy forests. Methods An experimental set-up using transplantation was insta...

159 forest relevés on sample plots (400 m2 each) at Smolenskoye Poozerye National Park were collected during the period from 2017 till 2022. Lichen diversity of was analyzed simultaneously. 25 lichen species preliminary list indicators biologically valuable landscapes in coniferous-broadleaved subzone European part Russia found plots. Two more (Pyrenula nitida and Toniniopsis separabilis) added...

PREMISE Lichens are one of the main structural components plant communities in North American boreal biome. They play a pivotal role lichen woodlands, large ecosystem situated north closed-crown forest zone, and south forest–tundra zone. In Eastern Canada (Quebec), there is remnant LW found 500 km its usual distribution range, Parc National des Grands-Jardins, originated mainly because wildfire...

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...

Community science-generated biodiversity data can provide essential information for understanding species distributions, behaviors and conservation statuses. However, their utility be limited due to high uncertainty variability in quality, especially small taxonomically difficult organisms like fungi insects. One important set of community-generated that are increasingly used by scientists Rese...

Global warming causes the replacement of lichens by shrubs in alpine and Arctic ecosystems. Since have lower albedo than lichens, this shrub encroachment can lead to a positive climatic feedback, resulting higher temperatures surroundings. Therefore, gaining knowledge on surface is important. Environmental factors also influence albedo, but often been neglected, potentially leading biased resul...

Quantifying abundance and distribution of plant species can be difficult because data are often inflated with zero values due to rarity or absence from many ecosystems. Terrestrial fruticose lichens (Cladonia and Cetraria spp.) occupy a narrow ecological niche and have been linked to the diets of declining caribou and reindeer populations (Rangifer tarandus) across their global distribution, an...
