Shifting baseline in macroecology? Unravelling the influence of human impact on mammalian body mass
Aim: Human activities have led to hundreds of species extinctions and have narrowed the distribution of many of the remaining species. These changes influence our understanding of global macroecological patterns, but their effects have been rarely explored. One of these patterns, the Bergmann's rule, has been largely investigated in macroecology, but often under the assumption that observed patterns reflect “natural” processes.
