Data from: No consistent effects of humans on animal genetic diversity worldwide

Human impacts on genetic diversity are poorly understood yet critical to
biodiversity conservation. We used 175,247 COI sequences collected between
1980 and 2016 to assess the global effects of land use and human density
on the intraspecific genetic diversity of 17,082 species of birds, fishes,
insects, and mammals. Human impacts on mtDNA diversity were taxon and
scale-dependent, and were generally weak or non-significant. Spatial
analyses identified weak latitudinal diversity gradients as well as
negative effects of human density on insect diversity, and negative
effects of intensive land use on fish diversity. The observed effects were
predominantly associated with species turnover. Time series analyses found
nearly an equal number of positive and negative temporal trends in
diversity, resulting in no net monotonic trend in diversity over this time
period. Our analyses reveal critical data and theory gaps and call for
increased efforts to monitor global genetic diversity.
