Cattle seed dispersal services and perspectives for management in a high biodiversity Mediterranean silvopastoral system
2019
In Mediterranean traditional silvopastoral systems are composed mostly with oaks, with an overall lack of fleshy-fruited species, key elements in Mediterranean flora. A mixed composition may enhance biodiversity and diversify fodder for livestock, and at the same time guarantee higher resistance, resilience and a richer network of ecological interactions. Here we investigated the interactions of cattle and native fleshy-fruited species in a high biodiversity silvopastoral system inside the last large forest remnant in western Sicily, Italy. Along two fruiting seasons we used sampling transects covering the gradient from the forest to the pastureland and analyzed 132 cattle dungs, of which 4…
Plant-animal seed dispersal interactions as key drivers of ecological restoration in a changing world
2022
Many global and European commitments state the need to plant billions of trees and restore millions of hectares of degraded ecosystems to contrast biodiversity loss, desertification and climate change. Seed dispersal is a crucial process promoting vegetation dynamics, and in the Mediterranean, up to 65% of woody plant species need animals for seed dispersal. Therefore, such mutualistic ecological interaction represents a key nature-based solution to help us reaching our commitments. In this presentation first we will report the strong expansion rate and correlated finescale spatio-temporal patterns of woody natural regeneration over a pastureland, using a spatially-explicit framework deploy…
