Abstract
Species may be more abundant in the centre of their geographic range or climatic niche (the abundant-centre hypothesis). Recently, Osorio-Olvera et al. (2020) reported strong support for the niche abundant-centre relationship. We demonstrate here that methodological decisions strongly affected perceived abundant-centre support. Upon re-analysis, we show that abundant-centre relationships are quite rare.
