Abstract Lichens are a well-known symbiosis between host mycobiont and eukaryote algal or cyanobacterial photobiont partner(s). Recent studies have indicated that terrestrial lichens can also contain other cryptic photobionts increase the lichens’ ecological fitness in response to varying environmental conditions. Marine live distinct ecosystems compared with their counterparts because of regul...

We review and present a synthesis of the existing research dealing with changing Arctic tundra ecosystems, in relation to caribou and reindeer winter ranges. Whereas pan-Arctic studies have documented the effects on tundra vegetation from simulated climate change, we draw upon recent long-term regional studies in Alaska that have documented the actual, on-the-ground effects. Our review reveals ...

To quantify the rate of oxidation of tritium gas (referred to as HT) to tritiated water in the environment, various woody and herbaceous plant leaves and roots, mosses and lichens taken from a forest and fields in Ibaraki prefecture, and a forest in Toki, Gifu prefecture, were investigated as to their ability to oxidize atmospheric HT in in vitro experiments. The HT oxidation activity in vegeta...

Experimental work on the control of photosystem II in the photosynthetic apparatus of higher plants, mosses and lichens is reviewed on a background of current literature. Transmembrane proton transport during photoassimilatory and photorespiratory electron flows is considered insufficient for producing the intrathylakoid acidification necessary for control of photosystem II activity under exces...

Macroecology and biogeography of microscopic organisms (any living organism smaller than 2 mm) are quickly developing into fruitful research areas. Microscopic organisms also offer the potential for testing predictions and models derived from observations on larger organisms due to the feasibility of performing lab and mesocosm experiments. However, more empirical knowledge on the similarities ...

Endozoochory plays a prominent role for the dispersal of seed plants. However, for most other plant taxa it is not known whether this mode of dispersal occurs at all. Among those other taxa, lichens as symbiotic associations of algae and fungi are peculiar as their successful dispersal requires movement of propagules that leaves the symbiosis functional. However, the potential for endozoochorou...

We investigated the potential for nonvascular epiphytic species (primarily lichens) to affect the quality of different host tree species for the vascular epiphyte Tillandsia usneoides in the southeastern USA. Different host tree species had substantially different abundances of Tillandsia, and these abundances were correlated with the composition of nonvascular epiphyte communities. In greenhou...

In Sweden ca. 20 000 ha forestland is fertilised each year. By using red-listed and ‘signal’ bryophytes and lichens as indicators, we investigated whether forest stands planned for fertilisation have a biodiversity value, and thus if restrictions due to conservation aspects are motivated. Species occurrences were registered in detailed line-transect analysis, with a record size of 10 × 10 m, in...

Lichens comprise highly diverse and complex microbial communities, the majority consisting of mycobiont, photobiont, Basidiomycetes yeast bacteriobiont (internal bacterial communities). In this study, diversity foliose lichen was reported. Next generation sequence (NGS) such as Illumina Sequencing (150*2) 16S rRNA (V3 V6 region) used to delineate communities associated with five samples. Bacter...
