The atmosphere is an important pathway for microplastic (MP) transport; however, observations are limited, as traditional sampling methods generally labor-intensive. Biological monitors (biomonitors) have been widely used a simple alternative to determine the abundance or presence of anthropogenic pollutants. Here, we compared effectiveness co-located lichen and moss species biomonitors atmosph...

Aim Although vascular epiphytes are important components of species richness and complexity of Neotropical forests, vascular epiphytes are under-represented in large scale biogeographical analyses. We studied the diversity, biogeography and floristic relationships of the epiphytic flora of the Yasunı́ region (Western Amazonia) in a Neotropical context, with special emphasis on the influence of t...

Abstract Cymodocea nodosa , a typical marine angiosperm species in the Mediterranean Sea, hosts range of epiphytic algae. Epiphyte abundance varies at different spatial scales, yet epiphyte diversity and community composition are poorly understood. This study explores epiphytes on C. from two reference meadows (Thasos, Vrasidas) one anthropogenically stressed meadow (Nea Karvali) northern Aegea...

Members of the sooty blotch and flyspeck (SBFS) complex are epiphytic fungi in the Ascomycota that cause economically damaging blemishes of apples worldwide. SBFS fungi are polyphyletic, but approx. 96% of SBFS species are in the Capnodiales. Evolutionary origins of SBFS fungi remain unclear, so we attempted to infer their origins by means of ancestral state reconstruction on a phylogenetic tre...

The N-acyl homoserine lactone (AHL)-mediated quorum-sensing system in the phytopathogen Pseudomonas syringae pv. syringae requires the AHL synthase AhlI and the regulator AhlR, and is additionally subject to regulation by AefR. The contribution of quorum sensing to the expression of a variety of traits expected to be involved in epiphytic fitness and virulence of P syringae were examined. Both ...

Epibiotic biofilms have the potential to control major aspects of the biology and ecology of their hosts. Their composition and function may thus be essential for the health of the host. We tested the influence of salinity on the composition of epibacterial communities associated with the brown macroalga Fucus vesiculosus. Algal individuals were incubated at three salinities (5, 19, and 25) for...
