The Tripartite Lichen : Involvement of Cyanobacteria and Bacteria in Its Morphogenesis.

is an epiphytic lichen-forming fungus mainly distributed in Western Europe and Macaronesia in well-structured forests with ecological continuity that lack eutrophication. It is considered to be threatened or extinct in many territories in Europe (IUCN). Despite its biological and ecological relevance, studies on this taxon are scarce.

Feeding the Brain: Effect of Nutrients on Cognition, Synaptic Function, and AMPA Receptors.

In recent decades, traditional eating habits have been replaced by a more globalized diet, rich in saturated fatty acids and simple sugars. Extensive evidence shows that these dietary factors contribute to cognitive health impairment as well as increase the incidence of metabolic diseases such as obesity and diabetes. However, how these nutrients modulate synaptic function and neuroplasticity is poorly understood.

Trebouxia lynnae sp. nov. (Former Trebouxia sp. TR9): Biology and Biogeography of an Epitome Lichen Symbiotic Microalga.

Two microalgal species, Trebouxia jamesii and Trebouxia sp. TR9, were detected as the main photobionts coexisting in the thalli of the lichen Ramalina farinacea. Trebouxia sp.

Biodiversity Patterns and Ecological Preferences of the Photobionts Associated With the Lichen-Forming Genus .

The worldwide, ecologically relevant lichen-forming genus currently includes 41 accepted species, of which the group (PSULgp) and the group (PSAXgp) have received considerable attention over recent decades; however, phycobiont diversity is poorly known in s. lat. Here, we studied the diversity of microalgae associated with 159 thalli collected from 30 locations, including nine spp.

Thallus Growth Stage and Geographic Origin Shape Microalgal Diversity in Ramalina farinacea Lichen Holobionts.

Lichen symbioses are microecosystems hosting many other living organisms besides the two major lichen symbionts (i.e., lichenized fungi [the mycobiont] and green microalgae or cyanobacteria [the photobiont]).
