IAS are listed second only to habitat loss and fragmentation and are among the major drivers of biodiversity loss in the recent Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES)<\/a> report. One example of how a single invasive species can disrupt an entire ecosystem and cause extensive damage is demonstrated by the sour fig plant (Carpobrotus edulis<\/em>) in the Berlengas archipelago, Portugal. \u00a0<\/em>It invades large areas by forming impenetrable mats of living and dead plant material, changes the dynamics of dunes by reducing the soil pH, modifies the nutrient dynamics, and prevents sand movement, all of which impedes the establishment and growth of native plants.<\/p>\n Other examples of the impacts caused by IAS in protected areas include the Everglades National Park in Florida, USA, which is suffering severe declines of mammalian and bird species due to the invasion of the Burmese python (Python bivittatus<\/em>). Marine protected areas in Florida and parts of the Caribbean are also invaded by introduced lionfish species (Pterois miles<\/em> and Pterois volitans<\/em>) which are impacting communities of native fish species. Seabird colonies in Alaska\u2019s Maritime National Wildlife Refuge were heavily impacted by non-native arctic foxes (Alopex lagopus<\/em>). Lastly, following the introduction and establishment of the widespread Japanese white-eye<\/a> (Zosterops japonicus<\/em>) in Hawaii Volcanoes National Park, it became a vector of introduced avian malaria, a disease widely decimating native bird populations.<\/p>\n The situation in other parts of the world is similar, for example, in South African national parks there are over 850 known alien species, of which 263 are invasive, and the majority comprise plants, followed by insects and mammals.<\/p>\n \u201cWe believe that PADDD events must account for invasive alien species as an important driver of biodiversity loss in order to improve conservation science and policy in protected areas<\/em>\u201d, said Desika Moodley, lead author of the paper published in NeoBiota<\/em>.<\/p><\/blockquote>\n Read the paper<\/strong><\/p>\n Moodley D, Foxcroft LC, Novoa A, Py\u0161kov\u00e1 K, Pergl J, Py\u0161ek P (2020) Invasive alien species add to the uncertain future of protected areas.
