Abstract As many other species within the genus Emilia, E. coccinea is herb that behaves as an environmental and agricultural weed. This fast-growing herb has the potential to rapidly colonize disturbed areas, waste grounds, gardens, forest edges, pastures, active and abandoned cultivated lands, roadsides, dry thickets and riverbanks. This species is adapted to grow in a wide range of environmental conditions and has wind-dispersed seeds, which are features that may facilitate its spread into new habitats. It is listed as invasive in Hawaii, Dominican Republic and New Caledonia.

Abstract Oldenlandia corymbosa is a widespread polymorphic weed with a pantropical distribution. It is fast-growing and can rapidly colonize disturbed areas, open sites, gardens, farmlands, forest edges, grasslands, roadsides and riverbanks. O. corymbosa also produces large volumes of tiny seeds that can be easily dispersed by water, animals and vehicles, or as a contaminant in soil and agricultural produce. Its weedy habit, preference for disturbed sites and tiny seeds all facilitate its spread and colonization of new habitats.

Abstract Lupinus plattensis is a fast-growing, perennial herb native to the USA. It can be weedy or invasive primarily in disturbed and ruderal areas, within and outside its native distribution range. The species spreads both by seed and vegetatively by rootstocks, and has the potential to rapidly colonize disturbed areas. Currently, it is listed as invasive only in the Dominican Republic, although no specific impacts have been recorded.

Abstract G. physocarpus is a shrub, widely naturalized in tropical, subtropical and semiarid ecosystems. It commonly grows as a weed in waste places, disturbed sites, open woodlands, grasslands, wetlands, and along roadsides and it is also planted as an ornamental in gardens, yards and parks (Wagner et al., 1999; Motooka et al., 2003; Queensland Department of Primary Industries and Fisheries, 2011). In Hawaii and Australia, this species has been recorded invading active pastures and sugarcane plantations as well as coastal and dry forests (Motooka et al., 2003; Queensland Department of Primary Industries and Fisheries, 2011). Features such as high drought tolerance, fast-growing, weedy behaviour, and wind-dispersed seeds are factors facilitating the invasion of this species into new habitats. In addition, each plant produces large numbers of small seeds which are successfully dispersed by wind aided by the tuft of silky hairs attached to each seed (Notten, 2010). Currently, G. physocarpus is listed as invasive in Hawaii, French Polynesia, the Canary Islands, New Caledonia, China and Australia and as potentially invasive in Cuba, Jamaica, India and Italy (Oviedo Prieto et al., 2012; DAISIE, 2014; PIER, 2014; USDA-ARS, 2014).

Abstract E. fosbergii is a cosmopolitan annual herb included in the Global Compendium of Weeds (Randall, 2012). It is fast-growing, with the capacity to grow as a weed and colonize disturbed areas, waste ground, gardens, abandoned farmland, coastal forests, forest edges, pastures, roadsides, rocky areas, and riverbanks (Wagner et al., 1999; Vibrans, 2011; Pruski 2014). It produces large amounts of wind-dispersed seeds (>5000 seeds per plant; Mejía et al., 1994) which is a feature facilitating the likelihood of spreading and colonizing new habitats. Currently, E. fosbergii is listed as invasive in Mexico, Central America, West Indies, and on several islands in the Pacific Ocean (see Distribution Table for details).

Abstract F. convolvulus is a weedy species of gardens, cultivated fields, open habitats, orchards, non-crop areas, waste areas, and disturbed sites. It is well-adapted to a wide range of climatic conditions and soils. This species is a prolific seed producer and has the potential to produce up to 30,000 seeds/plant. Seeds can be dispersed by farm machinery, and water. It is also a common contaminant of wheat and other cereal crops. F. convolvulus is often a serious weed in cereals, vegetables and horticultural crops (FAO, 2015). Currently, it is listed as invasive in the Dominican Republic, Cuba, Australia, New Caledonia, and New Zealand (Webb et al., 1988; MacKee, 1994; Wilson, 2008; Acevedo-Rodriguez and Strong, 2012), but it is also ranked as a serious weed in 20 crops in more than 41 countries around the world (Holm et al., 1991).

Solidago Sempervirens

Abstract Solidago sempervirens is a herb native to North America that has been introduced as an ornamental and to combat soil erosion and stabilize dunes. This species is highly tolerant of both saline soils and salt spray and can be found growing in coastal thickets, salt marshes, sand dunes and the banks of estuaries and lakes, but also in grasslands, disturbed sites, forest edges and along roadsides. This species is adapted to grow in a wide range of climates (from tropical to a humid continental and temperate oceanic climates) and produces large amount of wind-dispersed seeds, which are features that may facilitate its spread into new habitats. S. sempervirens also produces allelochemicals that suppress the establishment and growth of other plant species. Currently, it is listed as invasive in the USA, Japan, the Dominican Republic, the Azores and Australia.

Chloris Gayana

Abstract Chloris gayana is a robust, strongly stoloniferous grass native to Africa that has been extensively introduced as forage across tropical and subtropical regions. Traits such as its ability to grow in a wide range of environmental conditions, its drought-resistance and its ability to rapidly reproduce both by seeds and vegetatively have facilitated its escape from cultivation and subsequent naturalization. Once established, C. gayana often grows to form almost pure stands that smother native species. Currently, this species is regarded as an invasive in Australia, Spain, Argentina, Paraguay, Mexico, Costa Rica, Cuba, Anguilla, New Caledonia, New Zealand and Hawaii. It is also included in the Global Compendium of Weeds.

Abstract P. paniculatum is a fast-growing grass sometimes used as an "auxiliary forage" crop (PROTA, 2016). Within and outside its native distribution, P. paniculatum behaves as an environmental and agricultural weed and can be found growing along roadsides, in disturbed places, moist shrublands, low open grounds, brushy slopes, forests, open ground, croplands and pastures (Zuloaga et al., 2003; Más and Garcia-Molinari, 2006; Más and Lugo, 2013; AusGrass2, 2016). Plants produce numerous seeds with germination rates higher than 85% (range: 86.5 to 99%, PROTA, 2016). Currently, this species is listed as invasive on Hawaii, Cuba, Trinidad and Tobago, Samoa, Northern Marianas Islands, Micronesia, Fiji, French Polynesia, New Caledonia, Niue, Palau and the Solomon Islands (Wagner et al., 1999; Oviedo Prieto et al., 2012; PIER, 2016; Trinidad and Tobago Biodiversity, 2016).
