Abstract Cavanillesia platanifolia is a deciduous tree native to the Americas from Nicaragua to Peru, that has been introduced in Puerto Rico and Cuba. It is not listed as invasive in any country, although it is considered as potentially invasive species in Cuba, being categorised as a naturalized species with a tendency to proliferate at some localities, with a high diaspore production and high dispersal capacity. Due to its habitat being reduced by urbanisation and agriculture in its native distribution the species is Near Threatened, and is Endangered in Colombia.

Abstract Desmodium cajanifolium is a perennial shrub considered as invasive in Hawaii, USA, by Frohlich and Lau (2012), who reported it as a weedy species naturalised along roadsides, open forests and secondary vegetation on the Big Island and Kaua'i. At the same time, Benitez et al. (2012) report D. cajanifolium as a species that is rarely found along roadsides and in forests in Hawaii. D. cajanifolium is not listed as an invasive species on Pacific Islands Ecosystems at Risk (PIER, 2020). No details about its effects over other species or habitats are given.Desmodium cajanifolium is listed as potentially invasive in Cuba, being classified as a species with a tendency to proliferate in some areas and producing vast amounts of diaspores with a high dispersal capacity (Oviedo Prieto et al., 2012). It is considered as uncommon in parts of its native distribution (Flora of Nicaragua, 2020) and as scattered throughout its range (Flora of Panama, 2020).

Abstract Anredera vesicaria is a herbaceous vine native from the south of the USA to northern South America. It is cultivated as an ornamental for its fragrant flowers, and has been introduced in the Philippines and some Caribbean islands. It is not recorded as invasive in any country but is regarded as a potential invasive species in Cuba as it has become naturalized outside its native range, has a tendency to proliferate and has a high dispersal capacity. Although A. vesicaria appears in EDDMapS for USA, it is not included as an invasive but rather for "comparison reasons" without further details given. It is also reported in the Invasive Plant Atlas, but without any information. The species is not included in the latest FLEPPC Invasive Plant List Species.

Abstract Sterculia apetala is a tree native the tropics and subtropics of North, Central and South America, grown as an ornamental and shade tree and cultivated for its timber and edible seeds. It is reported as invasive in Puerto Rico, Cuba and Hawaii. In Hawaii, numerous seedlings and saplings that were originally growing close to pineapple plantations are now slowly spreading into nearby areas. Without seed predation or animal dispersal the seeds fall close to the parental plant, leading to almost pure stands of seedlings and saplings. In Cuba it is regarded as a transformer species, due to its high seed production and high dispersal capacity.

The yellow spotted stink bug (YSSB), Erthesina fullo Thunberg, is one of the most widely distributed phytophagous insect pests in Asia. YSSB is highly polyphagous and in China it feeds on over 57 host plants in 29 families, including some economically important fruit crops such as kiwifruit, pear, peach, apple, and pomegranate. With a primarily r-selected life history strategy, reproductive diapause, aggregation behavior, wide host range, high dispersal capacity, and close association with human-modified ecosystems, YSSB is a potentially invasive species that poses significant biosecurity threats to other countries outside its native range. This review summarizes basic and applied knowledge on the biology, ecology, and management of YSSB in China, with specific emphasis on its life history, host range, damage and impacts on economically important horticulture crops, and integrated pest management (IPM) approaches. The insights from the Chinese literature on this pest will help the countries outside its native range to conduct appropriate biosecurity risk assessments, develop a sound surveillance program, and develop an emergency response plan before its invasion of new geographic areas.

AbstractThousand Island Lake (TIL) is a typical fragmented landscape and an ideal model to study ecological effects of fragmentation. Partial fragments of the mitochondrial cytochrome oxidase subunit I gene of 23 island populations of Dendrolimus punctatus in TIL were sequenced, 141 haplotypes being identified. The number of haplotypes increased significantly with the increase in island area and shape index, whereas no significant correlation was detected between three island attributes (area, shape and isolation) and haplotype diversity. However, the correlation with number of haplotypes was no longer significant when the ‘outlier’ island JSD (the largest island) was not included. Additionally, we found no significant relationship between geographic distance and genetic distance. Geographic isolation did not obstruct the gene flow among D. punctatus populations, which might be because of the high dispersal capacity of this pine moth. Fragmentation resulted in the conversion of large and continuous habitats into isolated, small and insular patches, which was the primary effect on the genetic diversity of D. punctatus in TIL. The conclusion to emphasize from our research is that habitat fragmentation reduced the biological genetic diversity to some extent, further demonstrating the importance of habitat continuity in biodiversity protection.

History Of

Invasive plant species are expected to display high dispersal capacity but low levels of genetic diversity due to the founder effect occurring at each invasion episode. Understanding the history of invasions and the levels of genetic diversity of such species is an important task for planning management and monitoring strategy for these events. Peruvian Peppertree (Schinus molle L.) is a pioneer tree species native from South America which was introduced in North America, Europe and Africa, becoming a threat to these non-native habitats. In this study, we report the discovery and characterization of 17 plastidial (ptSSR) and seven nuclear (nSSR) markers for S. molle based on low-coverage whole-genome sequencing data acquired through next-generation sequencing. The markers were tested in 56 individuals from two natural populations sampled in the Brazilian Caatinga and Pampa biomes. All loci are moderately to highly polymorphic and revealed to be suitable for genetic monitoring of new invasions, for understanding the history of old invasions, as well as for genetic studies of native populations in their natural occurrence range and of orchards established with commercial purposes.

Abstract Pteris multifida is a herbaceous fern native to temperate and tropical eastern Asia and naturalized on many continents as a result of being widely cultivated. Although it is an urban weed, it is not considered by most countries as an invasive or noxious weed. There is no information available on the species affecting native species or natural habitats. Although one source lists P. multifida as an invasive species in many countries outside of Africa due to it being easily dispersed by spores, there are no references or further information to support this statement. It is reported as an alien invasive species in Germany, but only as occurring in sheltered sites, growing on light-vents in cellars and walls. A species assessment for Florida, USA indicates, P. multifida is neither a weed of natural habitats nor of agriculture. The species has not been listed as an invasive plant in any state or natural areas of the USA. However, P. multifida has been assigned a Tier II Invasive Species status (defined as having moderate negative impacts on wildlife or natural communities in Louisiana), but of limited concern and/or extent in Louisiana. Pteris multifida is recorded in Cuba as potentially invasive being categorized as a species with a tendency to proliferate in some areas and capable of producing vast amounts of diaspores with high dispersal potential. No further details are given about potential invasiveness.
