Invoking denialism does not strengthen invasion science

To the Editor,

Kuebbing and Nuñez (2018) defend their meta-analysis of the impacts of non-native plant species on native biodiversity (Kuebbing and Nuñez 2016), one of the articles explored as examples of selection bias in a cautionary article about generalising impacts across species (Guerin et al. 2018). However, Kuebbing and Nuñez (2018) rebut statements that were never made, yet fail to address key points or take into account recent movement in the literature when they conclude that generalisation of negative impacts across non-native species is supported.

Guerin et al. (2018) recognised that non-native species can have significant individual and cumulative impacts (Boltovskoy et al. 2018). Guerin et al. (2018) offered no objection to managers and scientists focusing on problematic species, since understanding and effective control is clearly needed in those cases. Our case focused on the risk of generalising from a biased set of problematic training species to many potentially...
