Where there is no deforestation, we walk through a forest and our gaze is captivated by the majesty of a centuries-old beech tree, the rustling of leaves, the flight of a bird. However, we rarely stop to think about what lives beneath our feet, just a few centimeters below, in a world of intricate connections that literally sustains the life we see above ground. This mostly invisible kingdom is the kingdom of fungi, a complex and fragile ecosystem that is suffering a mortal blow from logging. While we rightly worry about the loss of trees and their associated fauna, an entire universe of mycelia, symbioses, and essential biochemical processes is silently disappearing, with consequences we are only beginning to understand. This article aims to bring this silent crisis to light, exploring in depth the intricate relationships between trees and fungi, the mechanisms through which deforestation disrupts these networks, and the ripple effects throughout the forest ecosystem and beyond.
Urbanization represents one of the most significant anthropogenic landscape transformations, with profound and long-lasting effects on natural ecosystems. While public attention often focuses on the consequences for higher flora and fauna, fungal communities, essential components of terrestrial ecosystems, undergo equally significant but less visible alterations. This article explores in depth how urbanization processes affect local fungal biodiversity, analyzing changes in species composition, reductions in fungal richness, and the ecological implications of these transformations. Through scientific data, case studies, and statistical analyses, we seek to understand the complex dynamics governing fungal communities in urban and peri-urban environments. Fungi play fundamental ecological roles: as decomposers, they recycle essential nutrients; as mycorrhizal symbionts, they facilitate the uptake of water and minerals for plants; and as pathogens, they regulate plant populations. Their sensitivity to environmental changes makes them excellent bioindicators of ecosystem health. Understanding how urbanization modifies these communities is therefore not only a question of mycological interest, but has broader implications for the management of urban ecosystems and the conservation of biodiversity in human-influenced contexts.
The world of mycology is witnessing an extraordinary and unprecedented phenomenon: the migration of numerous fungal species to more northern latitudes. This article explores in detail the causes, dynamics, and consequences of this shift, offering a comprehensive overview based on up-to-date scientific data and field research.
