“…However, there was a signifi cant decrease in handling time with increase in temperature, which means that at high temperatures there is more time available for searching and a greater probability of fi nding more hosts. Similar fi ndings are reported by Flinn (1991), Menon et al (2002), Jones et al (2003), Zamani et al (2006) and ZandiSohani et al (2008).…”

“…First, the tropical climate in northern Parana State probably means that the parasitoids can survive actively (parasitizing) for a longer period. For example, the temperature during the assessments (around 20.54 C 6 1.45 C) was optimal for the development of aphidophagous parasitoids (Jones et al 2003, Rodrigues et al 2004, Sampaio et al 2005. Thus, the tropical climate in northern Parana allows aphidophagous parasitoids to appear in crops immediately after wheat emergence.…”

“…Although functional responses have been used to evaluate the biological control potential of introduced parasitoids (Greenberg et al 2001;Jones et al 2003), the first explicit test of the hypothesis that a known ecologically damaging invader might display a higher functional response than native and other less damaging invaders was by Bollache et al (2008), who showed that the invasive 'killer shrimp', Dikerogammarus villosus, had a higher Type II functional response than other native and introduced comparator species in Europe. Dick et al (2010) then used the comparative functional response method within an invasive species, showing that an invasive predatory amphipod, Gammarus pulex, had a higher Type II functional response when parasitized with an acanthocephalan worm, counter to the enemy release hypothesis, illustrating the utility of the method in tests of major invasion biology hypotheses (see below).…”

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
