Mediterranean odorscapes: the role of plants' volatile organic compounds in pollination networks
Abstract
At present, overexploitation of species, aggressive agricultural practices, land-use changes, biological invasions, pollution, and climate change represent, in descending order of magnitude, the main global-scale threats to biodiversity. Given that the majority of these phenomena represent threats also to plant–pollinator interactions worldwide, intensive research efforts across the world are focusing on disentangling the dynamics and structure of the p–p interactions, so that prevention, conservation, and restoration strategies can be effectively designed and implemented. In this context, this thesis focuses on the sensory ecology of pollination, in particular, on the role of floral signals as perceived by pollinating insects in structuring the pollination network of a natural community. I first find an unprecedented fine-tuning of floral scent and color implying a community-wide floral phenotypic integration according to the sensory systems of pollinators, especially bees. Next, by u ...
