Aim: Functional traits can help us to elucidate biogeographical and ecological processes driving assemblage structure. We analysed the functional diversity of plant species of different evolutionary origins across an island archipelago, along environmental gradients and across geological age, to assess functional aspects of island biogeographical theory. Location: Canary Islands, Spain. Major taxa studied: Spermatophytes. Time period: Present day. Methods: We collected data for four traits (plant height, leaf length, flower length and fruit length) associated with resource acquisition, competitive ability, reproduction and dispersal ability of 893 endemic, non-endemic native and alien plant species (c. 43% of the Canary Island flora) from the literature. Linking these traits to species occurrences and composition across a 500 m × 500 m grid, we calculated functional diversity for endemic, non-endemic native and alien assemblages using multidimensional functional hypervolumes and related the resulting patterns to climatic (humidity) and island biogeographical (geographical isolation, topographic complexity and geological age) gradients. Results: Trait space of endemic and non-endemic native species overlapped considerably, and alien species added novel trait combinations, expanding the overall functional space of the Canary Islands. We found that functional diversity of endemic plant assemblages was highest in geographically isolated and humid grid cells. Functional diversity of non-endemic native assemblages was highest in less isolated and humid grid cells. In contrast, functional diversity of alien assemblages was highest in arid ecosystems. Topographic complexity and geological age had only a subordinate effect on functional diversity across floristic groups. Main conclusions: We found that endemic and non-endemic native island species possess similar traits, whereas alien species tend to expand functional space in ecosystems where they have been introduced. The spatial distribution of the functional diversity of floristic groups is very distinct across environmental gradients, indicating that species assemblages of different evolutionary origins thrive functionally in dissimilar habitats.

Download and read online ebook Island Biogeography write by Robert J. Whittaker. This book was released on 2023-06-22. Island Biogeography available in PDF, EPUB and Kindle. Island biogeography is the study of the distribution and dynamics of species in island environments. Due to their isolation from more widespread continental species, islands are ideal places for unique species to evolve, but they are also places of concentrated extinction. Consequently, they are widely studied by ecologists, evolutionary biologists, and conservationists. This accessible textbook builds on the success and reputation of its predecessors, documenting the recent advances in this exciting field and explaining how islands have contributed to both theory development and testing. In addition, the book describes the main processes of island formation, subsequent dynamics, and eventual demise, explaining the relevance of island environmental history to island biogeography. The authors demonstrate the significance of islands as hotspots of biodiversity and of prehistoric and historic anthropogenic extinction. Since island species continue to feature disproportionally in the lists of threatened species today, the book examines both the chief threats to their persistence and some of the mitigation measures that can be put in play, with conservation strategies specifically tailored to islands.

Vegetation of the Canary Islands available in PDF, EPUB and Kindle. The volcanic and oceanic nature of the Canary Islands, its rich plant biodiversity and high rate of endemism, as well as the relict character of some of its plant communities make it a territory of great biological interest. The main geographic, climatic, bioclimatic, biogeographic and floristic features of the Islands are shown and related to the distributional pattern of potential communities along an altitudinal gradient. Current vegetation units and their ecology are described and illustrated with numerous pictures. Potential vegetation units are summarized and comprehensive maps of the potential natural vegetation for each island are given. Human impact on the natural landscape, the occurrence of invasive plants, and the probable impact of climate change on the flora and vegetation are discussed. The conservation status of flora and vegetation are assessed. Four appendixes include a syntaxonomical scheme, a brief history of botanical studies and explorations in the Islands, ethnobotanical notes, and a list of selected literature.
