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

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.

Automated summary

The study reanalyzes the changes in a cloud forest ant assemblage in response to climate change after a decade, attributing the differences to variations in sampling methods and effort between sampling periods. It emphasizes the importance of standardized methodology to distinguish true climate change effects from sampling bias when evaluating communities.
