Biogeography of pollinators in a changing world with special focus on the Aegean
Abstract
The analysis of species spatial patterns constitutes an important tool in geographical analyses for the understanding of observed biodiversity, the variation of biodiversity through time, and the differentiation among communities. Several factors and mechanisms determine species distribution patterns, their probability of presence or absence in an area, their richness and abundance, the differentiation of their composition among geographical areas, and their morphological and ecological characteristics. However, studies for understanding the mechanisms affecting species diversity patterns concern specific taxonomic groups, such as plants, birds, and mammals. For taxonomic groups with high species richness, such as insects, the available data are limited and are derived mainly from researches carried out on mainland, as well as in tropical areas. The current dissertation focuses on the investigation of factors affecting the distribution and diversity of pollinators, and the differentiat ...
