“…Refining risk assessment (RA) protocols is one such major challenge for the management of invasive species (Ricciardi and Rasmussen 1998;Parker et al 1999;Byers et al 2002;Andersen et al 2004;Kumschick et al 2012;Leung et al 2012;Kumschick and Richardson 2013), and impact is usually not satisfactorily included in RAs (Kumschick et al 2012). Including comparative functional responses in risk assessments for invasive species could be a useful way of improving the prediction of ecological consequences, namely impact (measures of per capita effects; Parker et al 1999) of species introductions and therefore increase the predictive power of RA.…”

“…This may, in part, be due to a lack of rigour in defining these hypotheses (Heger et al 2013) and lack of focus on demographic processes. These two major challenges need to be simultaneously addressed to advance the fundamental science of invasion ecology and to provide practical methodologies that prioritize and mitigate invasion threats by, for example, refining risk assessment protocols (Ricciardi and Rasmussen 1998;Parker et al 1999;Byers et al 2002;Andersen et al 2004;Kumschick et al 2012;Leung et al 2012) and managing biological communities to provide maximum biotic resistance (Taylor and Duggan 2012).…”

Advancing impact prediction and hypothesis testing in invasion ecology using a comparative functional response approach

Invasion ecology urgently requires predictive methodologies that can forecast the ecological impacts of existing, emerging and potential invasive species. We argue that many ecologically damaging invaders are characterised by their more efficient use of resources. Consequently, comparison of the classical 'functional response' (relationship between resource use and availability) between invasive and trophically analogous native species may allow prediction of invader ecological impact. We review the utility of species trait comparisons and the history and context of the use of functional responses in invasion ecology, then present our framework for the use of comparative functional responses. We show that functional response analyses, by describing the resource use of species over a range of resource availabilities, avoids many pitfalls of 'snapshot' assessments of resource use. Our framework demonstrates how comparisons of invader and native functional responses, within and between Type II and III functional responses, allow testing of the likely population-level outcomes of invasions for affected species. Furthermore, we describe how recent studies support the predictive capacity of this method; for example, the invasive 'bloody red shrimp' Hemimysis anomala shows higher Type II functional responses than native mysids and this corroborates, and could -013-0550-8 have predicted, actual invader impacts in the field. The comparative functional response method can also be used to examine differences in the impact of two or more invaders, two or more populations of the same invader, and the abiotic (e.g. temperature) and biotic (e.g. parasitism) context-dependencies of invader impacts. Our framework may also address the previous lack of rigour in testing major hypotheses in invasion ecology, such as the 'enemy release' and 'biotic resistance' hypotheses, as our approach explicitly considers demographic consequences for impacted resources, such as native and invasive prey species. We also identify potential challenges in the application of comparative functional responses in invasion ecology. These include incorporation of numerical responses, multiple predator effects and trait-mediated indirect interactions, replacement versus non-replacement study designs and the inclusion of functional responses in risk assessment frameworks. In future, the generation of sufficient case studies for a meta-analysis could test the overall hypothesis that comparative functional responses can indeed predict invasive species impacts.Biol Invasions (2014) 16:735-753 DOI 10.1007/s10530

“…Given the range of species that become invasive, such a scheme should be broadly applicable to any taxa (Nentwig et al 2010) and, given large numbers of species involved, should be efficient to apply (Andersen et al 2004;Hulme et al 2009). It should be possible to complete the scheme even where data are lacking, with uncertainty taken into account, documented and justified (Leung et al 2012;Vanderhoeven et al 2017).…”

Risk management to prioritise the eradication of new and emerging invasive non-native species

“…The difficulties in characterising the impacts of biotic invasions in formalised systems are seen in the complexity of their impacts -they are often indirect, affect populations or communities rather than individuals, depend on the context of the invaded ecosystem, and show unpredictable temporal dynamics (Andersen et al, 2004b;Simberloff, 2005). Recently, spatially explicit modelling of biotic invasions has been proposed for a more quantitative assessment of exposure risks and corresponding ecological effects (Allen et al, 2006;Andersen et al, 2004a). An open question regarding current risk assessment systems is if and how economic or socioeconomic valuation (see below) should be included in the procedures (Andersen et al, 2004b).…”

“…Prevention is widely considered the most cost-effective way for managing invasive species (Baker et al, 2005;Lodge et al, 2006;Wittenberg and Cock, 2001). The application of risk assessment systems (Table 2) is confronted with a number of practical problems (Andersen et al, 2004a;Baker et al, 2005;Simberloff, 2005). In particular, the efficacy of expert-based risk assessments is very low.…”

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.
