“…The majority of other locations containing one or two non-native colonists are close to, or located within, established research stations or popular tourist visitor sites (see Fig. 1 in Molina- Montenegro et al 2014). These findings are also closely consistent with areas predicted to be at highest risk of non-native species introductions, based on propagule pressure and climate suitability (Chown et al 2012b).…”

“…The physical, biological and chemical characteristics of colonised ground may affect the rate of spread. For example, disturbed ground may facilitate expansion of ruderal species (Grime 1977), as has been observed in Antarctica with P. annua (Olech 1996;Molina-Montenegro et al 2014), as could the spatial limits of appropriate microclimatic conditions.…”

“…Cities inside or near biodiversity hotspots may cause the local extinction of native and endemic species and the homogenization of the world's biota (McKinney 2006;McDonalD et al 2013;FerlanD 2015). A major concern is the increase in introductions of exotic and invasive species, associated with increasing transport of people and goods across the globe and the consequent disturbance of urban areas, which sharply increases the opportunities of non-native species to be introduced and become invasive outside their geographical range (McKinney 2006;KowariK & Von Der lippe 2007;HulMe 2009;SCDB 2014;Molina-Montenegro et al 2014). For example, human settlements import exotic species through commercial exchange and tourism.…”

Diversity and distribution of introduced and potentially invasive ant species from the three main ecoregions of Côte d’Ivoire (West Africa)

ABSTRACT. An important issue in biodiversity conservation is the early detection of introduced and invasive organisms and identification of regions that may either be points of introduction or be particularly prone to invasion. Among insects, ants are easily transported worldwide by humans, and several species, such as Solenopsis geminata or Pheidole megacephala, can be highly invasive. To establish an initial baseline for urban ant monitoring in Côte d'Ivoire (Western Africa), fifteen cities -equally distributed over the three main ecoregions of the country -were surveyed using tuna baits as sampling method. A total of 103 ant species from 22 genera and 5 subfamilies were collected. We identified 10 potentially invasive species, amongst them two new species for the country: Solenopsis geminata and Solenopsis globularia. Another highly invasive species, Paratrechina longicornis, was the most abundant species collected throughout the country. Potentially invasive ant species co-occurred with non-invasive species, and contributed importantly to the structure of ant assemblages of all sampled urban habitats. The present study provides evidence that introduced and invasive ant species are established in cities of Côte d'Ivoire, often in high numbers and are occurring over large areas of invasion.

“…For a couple of years P. annua has been classified as an invasive species on King George Island (Chwedorzewska and Bednarek 2012;Molina-Montenegro et al 2014;Polar Biol (2017) 40:939-945 943 Chwedorzewska et al 2015). Our research shows that the species exhibits the characteristics of invasion given the documented spread over time in the Point Thomas Oasis.…”

“…Their manuscript submission was received by the editorial staff on January 5, 2015 and published online on March 10, 2015 (Hughes et al 2015) we were working on the initial steps of eradication just as snow cover retreated in February and March 2015 (see report: Eradication of a nonnative grass P. annua L. from ASPA No 128 Western Shore of Admiralty Bay, King George Island, South Shetland Islands 2015). All of our earlier research regarding the biology and genetics of P. annua at Arctowski (Olech and Chwedorzewska 2011;Lityńska-Zając et al 2012;Wódkie-wicz et al 2013Wódkie-wicz et al , 2014Molina-Montenegro et al 2014;Pastorczyk et al 2014;Chwedorzewska et al 2015;Galera et al 2015;Giełwanowska et al 2015; was aimed at informed eradication/control of the species. Our actions preceded by the stated initial research enabled an analysis of the invasion process in the Antarctic and provided detailed documentation of eradication.…”

Poa annua, an alien species reported from the Antarctic continent and many Antarctic and sub-Antarctic islands, was accidentally introduced in the vicinity of the Polish Antarctic Station H. Arctowski. Recently the species has been found entering native plant communities. In almost 30 years it dispersed over 250 m from the site it was first observed and can therefore be considered invasive. We report the first steps to eradicate the species following the initial research to quantify the biology, ecology and genetics of the species. After detailed mapping of all 1439 tussocks located in the Arctowski Station area we removed 314 tussocks closest to a moss carpet formation (native plant community of high conservation value). All of the 49 tussocks growing in the Ecology Glacier forefield were removed. It is the biggest alien plant eradication act conducted so far in Antarctica. We plan to continue the eradication process and monitor the eradicated sites. This will provide valuable information on impacts and issues related to removal of alien species in the maritime Antarctic and will help in informing future decisions on management of other plant invasions in the region. Given the increasing human traffic to the Antarctic and the associated risks of invasion our results will be important not only for Arctowski but also for the whole Antarctic region.
