Beschreibung: All around the globe, humans have greatly altered the abiotic and biotic environment with ever-increasing speed. One defining feature of the Anthropocene epoch is the erosion of biogeographical barriers by human-mediated dispersal of species into new regions, where they can naturalize and cause ecological, economic and social damage. So far, no comprehensive analysis of the global accumulation and exchange of alien plant species between continents has been performed, primarily because of a lack of data. Here we bridge this knowledge gap by using a unique global database on the occurrences of naturalized alien plant species in 481 mainland and 362 island regions. In total, 13,168 plant species, corresponding to 3.9% of the extant global vascular flora, or approximately the size of the native European flora, have become naturalized somewhere on the globe as a result of human activity. North America has accumulated the largest number of naturalized species, whereas the Pacific Islands show the fastest increase in species numbers with respect to their land area. Continents in the Northern Hemisphere have been the major donors of naturalized alien species to all other continents. Our results quantify for the first time the extent of plant naturalizations worldwide, and illustrate the urgent need for globally integrated efforts to control, manage and understand the spread of alien species.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉van Kleunen, Mark -- Dawson, Wayne -- Essl, Franz -- Pergl, Jan -- Winter, Marten -- Weber, Ewald -- Kreft, Holger -- Weigelt, Patrick -- Kartesz, John -- Nishino, Misako -- Antonova, Liubov A -- Barcelona, Julie F -- Cabezas, Francisco J -- Cardenas, Dairon -- Cardenas-Toro, Juliana -- Castano, Nicolas -- Chacon, Eduardo -- Chatelain, Cyrille -- Ebel, Aleksandr L -- Figueiredo, Estrela -- Fuentes, Nicol -- Groom, Quentin J -- Henderson, Lesley -- Inderjit -- Kupriyanov, Andrey -- Masciadri, Silvana -- Meerman, Jan -- Morozova, Olga -- Moser, Dietmar -- Nickrent, Daniel L -- Patzelt, Annette -- Pelser, Pieter B -- Baptiste, Maria P -- Poopath, Manop -- Schulze, Maria -- Seebens, Hanno -- Shu, Wen-sheng -- Thomas, Jacob -- Velayos, Mauricio -- Wieringa, Jan J -- Pysek, Petr -- England -- Nature. 2015 Sep 3;525(7567):100-3. doi: 10.1038/nature14910.

Beschreibung: Island biogeographical models consider islands either as geologically static with biodiversity resulting from ecologically neutral immigration-extinction dynamics, or as geologically dynamic with biodiversity resulting from immigration-speciation-extinction dynamics influenced by changes in island characteristics over millions of years. Present climate and spatial arrangement of islands, however, are rather exceptional compared to most of the Late Quaternary, which is characterized by recurrent cooler and drier glacial periods. These climatic oscillations over short geological timescales strongly affected sea levels and caused massive changes in island area, isolation and connectivity, orders of magnitude faster than the geological processes of island formation, subsidence and erosion considered in island theory. Consequences of these oscillations for present biodiversity remain unassessed. Here we analyse the effects of present and Last Glacial Maximum (LGM) island area, isolation, elevation and climate on key components of angiosperm diversity on islands worldwide. We find that post-LGM changes in island characteristics, especially in area, have left a strong imprint on present diversity of endemic species. Specifically, the number and proportion of endemic species today is significantly higher on islands that were larger during the LGM. Native species richness, in turn, is mostly determined by present island characteristics. We conclude that an appreciation of Late Quaternary environmental change is essential to understand patterns of island endemism and its underlying evolutionary dynamics.〈br /〉〈span class="detail_caption"〉Notes: 〈/span〉Weigelt, Patrick -- Steinbauer, Manuel Jonas -- Cabral, Juliano Sarmento -- Kreft, Holger -- England -- Nature. 2016 Apr 7;532(7597):99-102. doi: 10.1038/nature17443.

Beschreibung: The Earth’s islands harbor a distinct, yet highly threatened, biological and cultural diversity that has been shaped by geographic isolation and unique environments. Island systems are key natural laboratories for testing theory in ecology and evolution. However, despite their potential usefulness for research, a quantitative description of island environments and...
