Multi-scale interplays of biotic and abiotic drivers shape mammalian sub-continental diversity over millions of years

Abstract: The reconstruction of deep-time diversity trends is key to understanding current and future species richness. Studies that statistically evaluate potential factors affecting paleodiversity have focused on continental and global, clade-wide datasets, and thus we ignore how community species richness build-up to generate large-scale patterns over geological timescales. If community diversity is shaped by biotic interactions and continental and global diversities are governed by abiotic events, which are the modu… Show more

“…Our results are consistent with a growing body of evidence from the fossil record for constrained diversification within the terrestrial realm [6,10,11,21,24,34,46,47]. Moreover, the regional-scale patterns we document for Phanerozoic tetrapods are highly congruent with those observed at smaller spatial scales, such as for local richness [24], which also show minimal increases from the late Palaeozoic-Mesozoic, a step-change across the K/Pg boundary, and no increase through the Cenozoic.…”

“…Patterns inconsistent with expansionism are recovered by analyses applying rigorous sampling standardization to estimate regional diversity of more restricted groups of tetrapods [6,[21][22][23] or over shorter intervals of time (the Mesozoic-early Palaeogene; [10,11]). Analyses of Phanerozoic tetrapod diversity at the local community scale [24] also contradict the expansionist model of diversification.…”

“…These correlations are both positive (Gλ temperature = 0.01, Gλ fragmentation = 4.61; electronic supplementary material, table S5), suggesting higher speciation rates during warmer periods with more fragmented landmasses. The influence of tectonics and global climate change on deep-time biodiversity dynamics has been reported in numerous studies at the mammalian scale, over long-time ranges and broadly distributed groups [10,[48][49][50][51]75] or over smaller time ranges and/or restricted groups [15,76,77]. Europe experienced important climatic and tectonic fluctuations between the Eocene and Oligocene, with (i) a significant global drop in temperature at the EOT followed by successive phases of warming at the beginning and the end of the Oligocene [53,78]; and (ii) an important phase of Alpine orogeny [31,79], which led to a decrease in continental fragmentation during the EOT [55].…”

“…There is substantial disagreement about how the exceptional diversity of terrestrial life was assembled over geological time [1][2][3][4][5][6][7] and the macroevolutionary importance of processes observed in ecological communities 6,8 . In particular, studies of the fossil record have been central to debates about models of diversification and community dynamics on geological timescales 8 , but nominally global and regional-scale patterns have been used to argue for both an "expansionist" diversification paradigm 1,3,4 , and for constrained or diversity-dependent diversification 2,7,[9][10][11] , resulting in great uncertainty.…”
