Ectomycorrhizal fungi in wood-pastures : Communities are determined by trees and soil properties, not by grazing

2019

Traditional rural biotopes such as wood-pastures are species-rich environments that have been created by low-intensity agriculture. Their amount has decreased dramatically during the 20th century in whole Europe due to the intensification of agriculture. Wood-pastures host some fungal species that prefer warm areas and are adapted to semi-open conditions, but still very little is known about fungi in these habitats. We studied how management, historical land-use intensity, present grazing intensity, time since abandonment, and stand conditions affect the species richness and community composition of ectomycorrhizal fungi. We surveyed fruit bodies on three 10 m × 10 m study plots in 36 sites…

Grazing and soil pH are biodiversity drivers of vascular plants and bryophytes in boreal wood-pastures

2016

Abstract Wood-pastures have been formed by traditional low-intensity livestock grazing in wooded areas. They host high biodiversity values that are now threatened by both management abandonment (ceased grazing) and agricultural intensification, and therefore these habitats are of conservation interest in Europe. In order to explore the effects of grazing on the biodiversity of boreal wood-pastures, we studied the communities of vascular plants and bryophytes in 24 currently grazed and 24 abandoned sites. In addition to the current management situation, we studied the effects of soil pH and moisture, tree density, historical land-use intensity, time since abandonment (in abandoned sites) and…

Contrasting responses of vascular plants and bryophytes to present and past connectivity in unmanaged grasslands

2022

AbstractThe area of semi-natural grasslands has decreased dramatically causing many grassland specialist species to persist in small habitat fragments. Furthermore, ecological communities once shaped by disturbances related to traditional agriculture now face the impacts of modern agriculture and urbanization. Many of the species have become endangered due to the combined effects of habitat destruction and degradation. We studied the responses of vascular plants and bryophytes to present and past connectivity in semi-natural grasslands, while accounting for the effects of local environmental conditions. We conducted vegetation surveys in 33 fragmented, unmanaged dry grasslands in Southwest …

Studio geoambientale dei Biotopi “Foci dell’Avisio”, “La Rupe” e “La Rocchetta” finalizzato alla Valutazione di Impatto Ambientale

2001

Thematic cartography in a GIS (Geographic Information System) have been employed to assess the direct impact produced on geological, geomorphologic and vegetation settings by the construction of a new motorway between the town of Mezzolombardo (TN) and the snout of the Non Valley (Rocchetta area). geological, geomorphologic and vegetation maps have been created at a 1:5,000 scale and implemented in a GIS. The geological map concerns not only the Mesozoic substratum and the size of the rocky outcrops, but also the complex Quaternary deposits occurring in the area. Similarly, by adopting the polygonal units of the geomorphologic map, the main goal was a complete and continuous definition of t…

Aspetti del Rosmarino-Thymetum capitati Furnari, 1965 presso la Torre di Monterosso (Sicilia centro-meridionale)

2014

A phytosociological study on the garrigue characterized by Rosmarinus officinalis and Thymbra capitata, settled on coastal lithosols unsuitable for agriculture, in the municipality of Realmonte (Southern Sicily, Agrigento province), is presented. The field work allowed, as well, to ascertain the vulnerability of the studied sites, due to the instability and erosion of the substrates, along with anthropogenic threats related to the urban sprawl affecting the area.
