TL;DR: This work analyzes 100 time series from biomes across Earth to ask how diversity within assemblages is changing through time and detects systematic loss of α diversity, but community composition changed systematically through time, in excess of predictions from null models.

TL;DR: For a set of 23 241 populations, 16 009 species, in 158 assemblages, significantly accelerating extinction and colonisation rates were detected, with both rates being approximately balanced.

TL;DR: New data and analyses are presented revealing fundamental flaws in a critique of two recent meta-analyses of local-scale temporal biodiversity change that raises points of uncertainty typical of all ecological studies, but does not provide an evidence-based alternative interpretation.

TL;DR: Novel evidence for widespread regulation of biodiversity is presented, suggesting that regulatory processes are occurring despite unprecedented environmental change, highlighting the need for community-level assessment of biodiversity trends, as well as extensions of existing theory to address open source pools and shifting environmental conditions.

TL;DR: It is shown that temporal shifts in species abundances underpin species coexistence and that spatiotemporal shifts in community composition minimize competitive interactions and help stabilize total abundance.
