To address this knowledge gap, we applied a primer-independent shotgun metatranscriptomic approach assess entire living canopy bark comprising prokaryotic eukaryotic primary producers, decomposers, various groups consumers. almost 1500 genera, found high microbial diversity on three species with distinct textures: oak (Quercus robur), linden (Tilia cordata), both rough bark, maple (Acer pseudoplatanus) smooth bark.

Mangrove ecosystems are globally significant for their biodiversity and ecosystem services but face persistent threats from invasive species anthropogenic disturbances. This study investigates the interactions between Cyperus rotundus, a widespread weed, fungal communities in mangrove-adjacent wetlands of Isla Santay, Ecuador. Using metagenomic sequencing ITS region, we analyzed diversity samples an anthropogenically pressured area non-impacted site. Results revealed differences microbial assemblages: rhizosphere sample disturbed exhibited lower richness was dominated by Magnaporthaceae (9%) Aureobasidium melanogenum (5%), both associated with stress-tolerant traits. In contrast, site showed higher diversity, Cladosporium dominicanum (62%) Talaromyces (11%) as dominant endophytic taxa. Principal Coordinates Analysis (PCoA) co-occurrence networks highlighted distinct partitioning two tissues, indicating that C. rotundus mediates composition response to environmental gradients. These findings underscore role plant’s success suggest leveraging beneficial fungi could enhance resilience support wetland restoration. By integrating molecular approaches ecological insights, this work contributes deeper understanding dynamics coastal informs targeted management strategies preserve mangrove habitats.

Abstract Bark surfaces are extensive areas within forest ecosystems, which provide an ideal habitat for microbial communities, through their longevity and seasonal stability. Here we a comprehensive account of the bark surface microbiome living trees in Central European forests, identify drivers diversity community composition. We examine algal, fungal, bacterial communities interactions using metabarcoding on samples from over 750 collected Biodiversity Exploratories northern, central, southern Germany. show that mutual biotic influence is more important than abiotic environment with regard to composition, whereas conditions geography alpha diversity. Important factors relative humidity light availability, decrease algal but strongly increase fungal In addition, temperature shaping community, higher leading homogeneous dominant fungi, high turnover communities. Changes dissimilarity one organismal group occur close relation changes other two, suggesting there between three major groups may be linked beneficial exchange. To understand functioning as whole, need further investigate functionality combine these results findings habitats such soil or canopy.

Lichens are an important part of forest ecosystems, contributing to biodiversity, the formation micro-niches and nutrient cycling. Assessing diversity lichenised fungi in complex such as forests, requires time substantial skills collecting identifying lichens. The completeness inventories thus largely depends on expertise collector, available for survey size studied area. Molecular methods surveying biodiversity hold promise overcome these challenges. DNA barcoding individual lichen specimens bulk collections is already being applied; however, eDNA have not yet been evaluated a tool surveys. Here, we assess which species can be detected swabbed from bark surfaces living trees central European forests. We compare our findings expert floristic carried out same plots about decade earlier. In total, 150 located three study regions across Germany. each plot, took one composite sample based six trees, belonging Fagus sylvatica , Picea abies Pinus sylvestris . method yielded 123 species, 87. total number found with both was 167, 48% were only eDNA, 26% methods. contained higher inconspicuous species. Many prevalent taxa reported could due gaps molecular reference databases. conclude that, currently, has merit complementary monitor at large scales, but cannot used its own. advocate further development specialised more complete

The yellow early marsh orchid (Dactylorhiza incarnata ssp. ochroleuca) is a critically endangered terrestrial in Britain. Previous attempts to translocate symbiotic seedlings site near the last remaining wild demonstrated some success, with 10% survival rate despite adverse weather conditions over two-year period. However, facilitate future reintroduction efforts or conservation translocations, more comprehensive understanding of fungal microbiome and abiotic soil characteristics at final required. Obtaining information on both community nutrient composition from sites has significant benefits may prove critical for success translocations involving threatened orchids. This preliminary study, conducted site, revealed correlation between relative abundance mycorrhizal order Cantharellales concentrations nitrate phosphate soil. Another group, Sebacinales, was found be distributed extensively throughout site. communities across entire orchid-hosting non-orchid-hosting soils discussed relation reinforcing current population preventing extinction this orchid.
