What is Biodiversity and elevation gradients: Insights on sampling biases across worldwide mountains about?

## Abstract ## Aim Identifying macroecological patterns and biases in species distribution is a challenging but essential task in biodiversity‐oriented studies. Despite extensive attempts to find consistent species richness elevation (SRE) patterns, the topic remains controversial owing to widespread conflicting, idiosyncratic and non‐generalizable underlying mechanisms. We used a meta‐analytical review to answer why patterns of species‐richness in elevation gradients remain elusive, a long‐standing, central but contentious macroecological and biogeographical question. ## Location Global elevation gradients. ## Taxon Major terrestrial taxa (invertebrates, vertebrates and plants). ## Methods We tested the effect of elevation on species richness using multilevel mixed‐effects meta‐analytical models. Data from 127 studies spawning almost one century of research were integrated to test the effect of elevation across distinct (1) SRE models, (2) quality of primary data (e.g. mountain sampling coverage), (3) biogeographic realms, (4) studied taxa and (5) organism mobility. ## Results The linear negative pattern showed the strongest model fit followed by the hump‐shaped and the linear pos
