“…Although it is often suggested or indicated that the British S. nobilis populations are descendants of specimens imported with fruits from the Canary Islands (e.g., Roberts 1995;Kulczycki et al 2012), this hypothesis is not well supported by current data. Since the 1960s, different phytosanitary treatments and transport techniques have become standard procedure in international trade and dramatically reduced the amount of alien spiders transported to Europe via shipping, especially after 1971 (Hallmann 2007;Nentwig 2015). Flourishing British populations of S. nobilis were not found until 1986 (Portsmouth area), followed by subsequent records and the observation of rapid colonization events (Snazell and Jones 1993).…”

The Noble False Widow, Steatodanobilis (Thorell, 1875) (Araneae, Theridiidae), is, due to its relatively large size and potential medical importance, one of the most notable invasive spider species worldwide. Probably originating from the Canary Islands and Madeira, the species is well established in Western Europe and large parts of the Mediterranean area and has spread recently into California and South America, while Central European populations were not known until 2011. We report on long-time observations that reveal that at least two flourishing populations in Germany (Cologne) have been present for over five years, while in Ecuador one population has been observed between 2014 and 2018 and several other records were made in other parts of the country. Data obtained from the British Spider Recording Scheme demonstrate that the species moved significantly northwards since the report of the first populations in the very South of England, after several decades of relative stasis. The sudden northward expansion highly correlates with a massive rise in press coverage of the species. In the Americas, S.nobilis is currently known from four countries (USA, Chile, Ecuador, Colombia), and available DNA barcoding data obtained for specimens from this area suggest that multiple introductions occurred within each country. Using ecological niche modeling, we identified suitable climate regions for the species and discuss possible reasons for its current spread. We propose that seaside cities and villages with a temperate oceanic or Mediterranean climate are especially favourable potential habitats for S.nobilis and will face the highest colonization pressure in the future, while tropical upland regions with temperate climates are also vulnerable to invasion by S.nobilis.

“…Simberloff, 2005). Context specific risk assessments allow for a comprehensive risk management, i.e., different management measures are combined to optimize the cost-benefit balance (Hallman, 2007). The risk management of Mediterranean fruit fly introductions through trade of pink tomatoes from Northern Africa to the U.S. combines regulations about the origin of the product, restrictions on the seasons when trade is allowed, and a number of measures during production and transport (Hallman, 2007).…”

How to Achieve Effectiveness in Problem-Oriented Landscape Research: The Example of Research on Biotic Invasions

It is increasingly expected from environmental research such as landscape research that science directly contributes to the solving of pressing societal problems. However, despite increased efforts to direct research towards societal problems, it is not obvious if science has become more effective in supporting environmental problem-solving. We present in this article a framework that facilitates the analysis and design of problem-orientation in research fields. We then apply the proposed framework to a concrete example of a problem-oriented landscape research field -namely research on biotic invasions. Invasion research addresses the problem that some organisms, that have been introduced by humans to a new geographic area where they were previously not present, spread in the landscape and pose negative impacts.We argue that problem-oriented research is more than applied research. Besides research on specific questions it also encompasses boundary management, i.e., deliberations among experts and stakeholders on the framing of adequate research questions about processes, values and practices for effective problem-solving. We postulate that such research may assist problem-solving in three ways, by analysing causal relationships (systems knowledge), clarifying conflicts of interests and values (target knowledge), or contributing to the development of appropriate means for action (transformation knowledge).We show that over the past decades a broad range of different research approaches has emerged in the young field of invasion research in order to produce systems, target and transformation knowledge for invasive species management. Early research in the field was dominated by the development of systems knowledge, but increasingly the three knowledge forms are Boundary management in invasion research is mainly restricted to informal networks (communities of practice), while formal processes such as transdisciplinary research are scarce. We suggest that the paucity of structured and explicit boundary management processes will limit the future development of a more effective science for invasive species management. In particular, we envisage three obstacles that can only be removed through explicit boundary management. First, the existing theoretical frameworks are currently only partly able to integrate natural and social sciences research on the processes underlying invasions. Second, a clarification of the normative thinking about alien plant invasions is needed. Third, research on transformation knowledge has so far not fundamentally challenged the existing conceptual framing and institutional setup of invasive species management.

“…The framing of research based on pathways has improved risk assessments for managers by suggesting new forms of context dependence. For instance, risk management of Mediterranean fruit fly introductions to the US, through trade of pink tomatoes from Northern Africa, combines regulations based on the origin of the product, trade restrictions based on the season, and preventative measures during production and transport (Hallman 2007). Although vector science has helped to better understand and manage the spread of alien species, it does not solve the problem of managing impacts in invaded habitats.…”

A Habitat-Classification Framework and Typology for Understanding, Valuing, and Managing Invasive Species Impacts

Management of Invasive Weeds

It is frequently lamented that invasion biology has not been very successful in developing reliable generalizations for management. In particular, there is an urgent need to improve the understanding and assessment of impacts of invasive species. We argue that a refined conceptualization of biotic invasion derived from a management perspective, rather than purely from ecological theory, can help to better understand, value and manage impacts of invasive species. We propose a habitat-classification framework on the basis of four habitat types that are defined by their differences in type and degree of human modification, and differences in human valuation. The first type, anthropogenic habitat, encompasses highly disturbed and anthropogenic areas such as agriculture, plantation forestry, or urban areas. The second type, reference habitat, represents relatively undisturbed habitat dominated by native species. The third type, abandoned habitat, involves habitats that currently experience relatively little human interference but that have been highly disturbed or managed in the past, e.g., old fields or abandoned plantation forests. The fourth habitat type, designed habitat, involves situations where humans deliberately and strongly manipulate a habitat to create a new habitat that primarily suites conservation objectives (e.g., restoration of a former native habitat). These four habitat types differ in invader characteristics, invader impacts, management strategies, and research needs. Our typology may help stimulate more interdisciplinary research yielding improved conceptual and practical understanding of impacts of invasive species.
