Lichens are traditionally defined as a symbiotic relationship between fungi and algae and/or cyanobacteria. This union forms unique structure called the thallus, which attaches to surfaces such rocks tree bark. Recent reports challenge view that lichens comprised of one fungus photobiont, instead suggest they consortium microbes. Much lichen biology remains unknown most our knowledge is limited...

Lichens cover nearly 7% of the earth’s surface and in eastern Canada, lichen woodlands occupy over 300,000 km2. Reindeer lichens (genus Cladonia), are main component they play a crucial role boreal forest ecology. We study, for first time, bacterial community four species reindeer from North America’s forests. Using 16S rRNA gene, we characterize 189 samples. aim to analyse effect host-identity...

Antibacterial activity of acetone, methanol and aqueous extract prepared from some lichen species were evaluated against five bacterial strains viz. Staphylococcus aureus, Escherichia coli, Vibrio cholerae, Shigella dysenteriae. Shigella flexneri The aqueous, methanol and acetone extracts exhibited a variable range of antibacterial activity to bacterial strains. The acetone and methanol extract...

The study introduces the genus Mycobilimbia, from South Korea. M. philippina is reported here as being new to the country. Characteristic features of the species are crustose thallus, globose apothecia, K-proper exciple and hypothecium, Biatora-type asci, 3-septate fusiform ascospores, and a lack of secondary compounds.

Mediterranean gorgonian forests are threatened by several human activities and are affected by climatic anomalies that have led to mass mortality events in recent decades. The ecological role of these habitats and the possible consequence of their loss are poorly understood. Effects of gorgonians on the recruitment of epibenthic organisms were investigated by manipulating presence of gorgonians...

The primary productivity of four species of crustose coralline algae was measured as a function of depth (0–18 m) and irradiance on samples collected from and growing upon the windward coral reef at Lizard Island, northern Great Barrier Reef, Australia. Significantly higher productivities were measured in the field than in the laboratory. Maximum gross oxygen production in situ varied from 12.8...
