Reported climate change impacts on cloud forest ants are driven by sampling bias: A critical evaluation of Warne et al. (2020)

Abstract

We present a reanalysis of the study by Warne et al. (2020), where authors reported substantial changes through time in a cloud forest ant assemblage in response to climate change after a decade. We show that these changes are due to major differences between the sampling periods in terms of sampling methods and effort. We stress the need for a fully standardized methodology to distinguish true climate change effects on communities from sampling bias.
