This study aims to explore and identify the types of Lichenes that exist at Mutis Mount Area, Noepesu Village, West Miomaffo District, Biology Education Laboratory, University Timor. research was conducted for 6 months starting from May-October 2022. is descriptive qualitative research. Sampling used a purposive sampling method. The collected were identified based on their characteristics using...

Abstract Lichens are one of the most responsive components ecosystem to reactive forms nitrogen. In this work, we selected lichen genera Cladonia and Usnea , composed terricolous epiphytic lichens respectively, described as sensitive nitrogen, test effects different doses nitrogen on physiological parameters (photobiont mycobiont vitality, chitin quantification, content stable isotopes analysis...

Coastal (CTR) and inland temperate rainforests (ITR) in western North America share a rich oceanic lichen flora. The distinctive Methuselah’s beard (Usnea longissima Ach.) is an exception to this pattern of shared distributions, with very few ITR locations. Does absence reflect dispersal limitations or climatic intolerance? To answer question, we transplanted U. thalli from the CTR three locati...

Lichenized fungi as a multicomponent biological system are an interesting but difficult research object. In view of the complex interaction myco- and photobiont, slow growth natural thalli, their exceptional exactingness to environmental factors, study characteristics lichens is significantly difficult. This article discusses problem studying anatomical morphological structure photobiont lichen...

The paper presents a multidimensional analysis of pine-birch forest lichens in the vicinity Big Kyzykul Lake (Minusinsky District, Krasnoyarsk Krai). studies on species composition were conducted from 2013 to 2016. material was collected summer and autumn months by route method. Based authors own collections, determined for first time, including 46 22 genera 11 families. list lichen study area ...

Abstract Antarctica is a natural research laboratory thanks to its unique climate, geography, flora and fauna. The conservation of Antarctica's environment monitored through the Madrid Protocol; however, there are local pollution problems associated with human activities such as tourism; in particular, negative impacts on air quality from use fossil fuels. In this work, we studied for first tim...

Abstract Background Indoor air quality (IAQ) is a concern in kindergartens as children spend much of their time there. Yet, there shortage biological indicators needed for assessing IAQ. Thus, this study evaluated IAQ using transplanted lichen Usnea misaminensis indicator. Methods Lichen samples, collected from Bukit Larut, Perak, Malaysia, were exposed to indoor and outdoor environments an urb...

Abstract There is considerable scientific interest as to how terrestrial biodiversity in Antarctica might respond, or be expected climate change. The two species of vascular plant confined the Antarctic Peninsula have shown clear gains density and range extension. However, little information exists for dominant components flora, lichens bryophytes. One approach has been look at change using alt...

The heavy metal Cd accumulates in trophic chains, constituting a toxic element for photosynthesizing organisms, including the algal photobionts of lichen. Thus, as lichens respond differently to toxicity, we hypothesized that species Parmotrema tinctorum and Usnea barbata, commonly sampled Cerrado ecoregion, could be sensitive and, therefore, used biomonitor dispersion this metal. We also aimed...
