Studies of the water-physical, physical-chemical and biological properties meadow-chernozem soils were carried out on a rice irrigation system located in present-day delta Kuban River. Rice have good water general physical humus layers. An increase compaction is observed lower horizons these soils. Meadow-chernozem are distinguished by low content organic matter arable (3,2-3,4 %), neutral reac...

Desert truffles belonging to Terfezia are well known mycorrhizal members of the mycota of the Mediterranean region and the Middle East. We aimed to test (i) whether the morphological criteria of Terfezia species regularly collected in Spain enable their separation and (ii) whether the previously hypothesized edaphic/biotic specificity of one group could be confirmed by study of a larger number ...

The vast forests of the Pacific Northwest region of the United States, an area outlined by the states of Oregon, Washington, and Idaho, are well known for their rich diversity of macrofungi. The forests are dominated by trees in the Pinaceae with about 20 species in the genera Abies, Larix, Picea, Pinus, Pseudotsuga, and Tsuga. All form ectomycorrhizas with fungi in the Basidiomycota, Ascomycot...

Canonical correlations analysis uses a secondary set of multivariate observations to correlate with, and thereby help to explain, differences among a primary set of multivariate observations. In ecology, the variables of the primary data set may be of the “presence/absence” type, or they may be the abundances of individual species in a species list, whereas the secondary set often involves envi...
