Fungi ecological niches of the genus Fusarium Link.

Abstract

Climatic variations and modern agricultural technologies change the fungi distribution area ofthe genus Fusarium Link., and lead to their dominance in pathocomplexes. The parasitic activity of fusarium fungi and localization of their ecological niches is determined by the activity of constantly expanding environmental and anthropogenic drivers. The fundamental niches of Fusarium pathogens are characterized by complexity and multidimensionality. Realized ecological niches change in space and time at the ontogenesis different stages of pathogenic micromycetes; the same species shows high heterogeneity in implementing its fundamental niche depending on environmental factors and the host plant species. The overlap level of ecological niches and interspecific relationships largely determine the species composition of the pathogenic complex of adiscrete phytocenosis.
