“…Regional coordination and cooperation on invasive species research and action may be necessary to curb invasions in the tropics. The proximity and connectedness of regional neighbors argues for sharing information and experiences, and a common regional policy on prevention (Soliman et al 2016). However, although regional cooperation on other environmental issues is common in Southeast Asia, East Africa, and the Neotropics, the National Reports to the CBD suggest that each tropical country tackles invasive species largely in isolation, relying on global resources, such as the Global Invasive Species Database (http://www.iucngisd.org/gisd/), rather than on neighbors' collective experience.…”

Most biological invasion literature—including syntheses and meta-analyses and the resulting theory—is reported from temperate regions, drawing only minimally from the tropics except for some island systems. The lack of attention to invasions in the tropics results from and reinforces the assumption that tropical ecosystems, and especially the continental tropics, are more resistant to invasions. We have critically assessed biological invasions in the tropics and compared them with temperate regions, finding relatively weak evidence that tropical and temperate regions differ in their invasibility and in the traits that determine invader success and impacts. Propagule pressure and the traits that promote adaptation to disturbances (e.g., high fecundity or fast growth rates) are generally favorable to invasions in both tropical and temperate regions. We emphasize the urgent need for greater investment and regional cooperation in the study, prevention, and management of biological invasions in the tropics. Expected final online publication date for the Annual Review of Ecology, Evolution, and Systematics, Volume 52 is November 2021.

“…The majority of the invasion science literature originates from continents rather than from islands, and more research designed to understand island invasion biology is needed [31]. The connectedness of regional islands argues for stronger collaborations among regional invasion biologists [27,32]. The immense cost associated with invasive alien species calls for greater coordination of management actions and policy agreements regionally and globally [33].…”

Infestations of Aulacaspis yasumatsui Reduce Asexual Propagation and Transplantation Success of Cycas revoluta Plants

Cycad transplantation and asexual propagation by stem cuttings are highly successful horticultural procedures because the manoxylic stems contain copious nonstructural carbohydrates. The success of these horticultural procedures may be impaired by antecedent abiotic or biotic stress that decreases stem nonstructural carbohydrate content. The armored scale Aulacaspis yasumatsui Takagi has emerged as a global threat to cycad conservation, and the direct influence of A. yasumatsui herbivory on cycad transplantation or asexual propagation outcomes has not been adequately determined. Cycas revoluta Thunb. plants were infested with A. yasumatsui for 0, 20, or 40 weeks to determine the influence of infestation duration on transplantation or asexual propagation success. Following 20 weeks of infestation in one study, 100% of the undisturbed replications but only 60% of the transplanted replications survived. Following 40 weeks, 80% of the undisturbed replications but only 40% of the transplanted replications survived. Following 20 weeks of infestation in a second study, 100% of the intact replications but only 43% of the cuttings survived. Following 40 weeks, 86% of the intact replications and none of the cuttings survived. Leaf number and root, stem, and leaf dry weights followed similar trends, with declines in these metrics occurring with longer infestation durations. These outcomes indicated that adding the stress of asexual propagation or transplantation to C. revoluta plants that were damaged by A. yasumatsui herbivory decreased subsequent plant health and increased mortality.

“…20.3. In many developing countries like South Africa, decisions need to be made with limited funds and expertise available (see also Soliman et al 2016 for southeast Asia). Even though RAAT can take several days to complete, it is less labour-intensive than collecting all the detailed information as outlined in the NEM:BA A&IS Regulations.…”

Biological Invasions in South Africa

Risk analysis is an important decision-support tool for the management of biological invasions. South Africa, as a signatory to international agreements, has enacted legislation requiring risk analyses to be conducted if trade is to be restricted or regulated and if alien species are to be introduced. In this chapter, we outline the various needs for risk analyses for biological invasions in South Africa, summarise the current status, and make recommendations for a way forward. In particular, we highlight the need to move away from approaches that are purely based on expert opinion or entirely reactive, and propose a new system and process which includes the use of a structured risk analysis framework with clear guidelines to avoid expert bias. We highlight the need to assess risk, consider risk management options (including benefits), and to develop clear recommendations. The proposed process also involves the review of recommendations by an independent panel. We further note that the effectiveness of such approaches will be defined by their transparency, their accuracy, how feasible they are to implement in practice, and the trust that people have in the system.
