A total of 520 overwintered sclerotia were collected from surface of soil under mulberry trees in six locations in Korea during February in 2006 and 2007. The collected sclerotia were tested for their germination in vitro and identified based on their morphological characteristics. Out of all sclerotia tested, 52.3% of the sclerotia germinated and produced two types of apothecia. The two types ...

today, extensive improvements in fields of soil mapping have increased the purity and accuracy ofsoil maps. usual mapping methods moreover depend on skills and experience of surveyor inidentifying and delineating the boundaries, also need the high cost and time consuming that face thesoil mapping with restrictions. in this study, aerial photographs with 1/40000 scale were used in orderto prepar...

Soil herpetofauna biodiversity is conservatively estimated as 2775 species, made up of 10% and 28% of Amphibia and Squamata, respectively. Neglect in their taxonomy, ecology and standard sampling methodologies suggests that proportions, as well as numbers, are likely to be far higher. Like invertebrate soil macrofauna, the majority of species live within the first few centimetres of leaf litter...

Microbial ecological studies have been remarkably promoted by the high-throughput sequencing approach with explosive information of taxonomy and relative abundance. However, relative abundance does not reflect the quantity of the microbial community and the inter-sample differences among taxa. In this study, we refined and applied an integrated high-throughput absolute abundance quantification ...

We report here the draft genome sequence of a novel UV-resistant bacterium isolated from dry soil on the south coast of Puerto Rico. Based on polyphasic taxonomy, strain MC1A represents a new species and the name Solirubrum puertoriconensis is proposed. Assembly was performed using NGEN Assembler into eight contigs (N50 = 1,292,788), the largest of which included 1,549,887 bp. The draft genome ...

Mediterranean biomes are biodiversity hotspots, and vineyards are important components of the Mediterranean landscape. Over the last few decades, the amount of land occupied by vineyards has augmented rapidly, thereby increasing threats to Mediterranean ecosystems. Land use change and agricultural management have important effects on soil biodiversity, because they change the physical and chemi...
