Fourteen degrees of latitude and a continent apart: comparison of lichen activity over two years at continental and maritime Antarctic sites [PDF]

open access: yes, 2010
There are marked declines in precipitation, mean temperatures and the number of lichen species with increasing latitude in Antarctica. However, it is not known which factors are the predominant controllers of biodiversity changes.

Environment and host identity structure communities of green algal symbionts in lichens.

open access: yesNew Phytologist, 2018
An understanding of how biotic interactions shape species' distributions is central to predicting host-symbiont responses under climate change. Switches to locally adapted algae have been proposed to be an adaptive strategy of lichen-forming fungi to ...

Fungal Diversity in Lichens: From Extremotolerance to Interactions with Algae

open access: yesLife, 2018
Lichen symbioses develop long-living thallus structures even in the harshest environments on Earth. These structures are also habitats for many other microscopic organisms, including other fungi, which vary in their specificity and interaction with the ...

High potential for weathering and climate effects of non-vascular vegetation in the Late Ordovician [PDF]

open access: yes, 2016
It has been hypothesized that predecessors of today’s bryophytes significantly increased global chemical weathering in the Late Ordovician, thus reducing atmospheric CO2 concentration and contributing to climate cooling and an interval of glaciations ...

Identifying the origins of local atmospheric deposition in the steel industry basin of Luxembourg using the chemical and isotopic composition of the lichen Xanthoria parietina [PDF]

open access: yes, 2008
Trace metal atmospheric contamination was assessed in one of the oldest European industrial sites of steel production situated in the southern part of the Grand-Duchy of Luxembourg.

Comparing Sanger sequencing and high-throughput metabarcoding for inferring photobiont diversity in lichens

open access: yesScientific Reports, 2018
The implementation of HTS (high-throughput sequencing) approaches is rapidly changing our understanding of the lichen symbiosis, by uncovering high bacterial and fungal diversity, which is often host-specific.

Diversity of Lecidea (Lecideaceae, Ascomycota) species revealed by molecular data and morphological characters [PDF]

open access: yes, 2002
The diversity of lichens, especially crustose species, in continental Antarctica is still poorly known. To overcome difficulties with the morphology based species delimitations in these groups, we employed molecular data (nuclear ITS and mitochondrial ...

Investigation of antioxidant, antimicrobial and toxicity activities of lichens from high altitude regions of Nepal

open access: yesBMC Complementary and Alternative Medicine, 2017
Background Several lichen species are reported to be used tradiationally in many theraupatic practices. Many lichen species are reported as sources of several bioactive natural compounds.

The lichen flora of the Malbork Castle (N. Polami)

open access: yesActa Mycologica, 2014
In the present study 32 species of lichens were found. The most numerous were crustose lichens. which are typical of rocks. The follwing species which are known to occur rarely in Poland were identified: Acarospora cf.

Effects of Growth Media on the Diversity of Culturable Fungi from Lichens

open access: yesMolecules, 2017
Microscopic and molecular studies suggest that lichen symbioses contain a plethora of associated fungi. These are potential producers of novel bioactive compounds, but strains isolated on standard media usually represent only a minor subset of these ...
