Individuals moving to new areas usually 18 confront a different set of biotic and abiotic variables, and most dispersed individuals do not 19 survive. However, if they are capable of surviving and adapting to the new conditions, they may 20 establish self-sufficient populations, colonise the new areas, and even spread into nearby 21 locations (Mack et al. 2000). In doing so, they will produce ecological transformations in the 22 new areas, which may lead to changes in other species’ populations and communities, speciation 23 and the formation of new ecosystems (Wilson et al. 2009). 24 25 Human extra-range dispersals since the Pleistocene have produced important distribution 26 changes across species of all taxonomic groups. Along our prehistory and history, we have aided 27 other species’ extra-range dispersals either by deliberate translocations or by ecological 28 facilitation due to habitat changes or modification of ecological relationships (Boivin et al. 29 2016). -
Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks
Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks By Jennifer Lynn Imamura A dissertation submitted in partial satisfaction of the requirements for the degree of Doctor of Philosophy in Environmental Science, Policy, and Management in the Graduate Division of the University of California, Berkeley Committee in charge: Professor George Roderick, Chair Professor Claire Kremen Professor Bruce Baldwin Spring 2019 Abstract Exotic Species and Temporal Variation in Hawaiian Floral Visitation Networks by Jennifer Lynn Imamura Doctor of Philosophy in Environmental Science, Policy, and Management University of California, Berkeley Professor George Roderick, Chair Many studies have documented the negative impact of invasive species on populations, communities, and ecosystems, although most have focused solely on antagonistic rather than mutualistic interactions. For mutualistic interactions, such as pollination, a key to understanding their impacts is how invasive species interact with native species and alter interaction networks. Chapter 1 explores the impacts of invasive species on islands, particularly in regard to plants, pollinators, and how these exotic species attach to existing pollination interaction networks. Island pollination networks differ from mainland counterparts in several important characteristics, including fewer species, more connectance, and increased vulnerability to both invasion and extinction. A progression of invasion has been previously proposed, through which supergeneralist native species -

However, functional traits such as nesting behavior, flight range, and body size can limit their dispersal. In this study, the bee faunas of seven different islands or island groups (Anholt, Canary Islands, Fiji Islands, Hawaiian Islands, Madeira, Malta, and Sri Lanka) were analyzed by comparing them to the mainland bee fauna.
