Data from: Effects of climate and topography on the diversity anomaly of plants disjunctly distributed in eastern Asia and eastern North America
<p><b>Aim: </b>Differences in physiography have been proposed to explain the diversity anomaly for vascular plants between environmentally similar regions of eastern Asia (EAS) and eastern North America (ENA). Here, we use plant species within disjunct genera to examine whether differences in topography contribute to the diversity anomaly and whether the richness–environment relationships differ between regions. Disjuncts are used to ensure that the diversity anomaly relates to post-disjunction evolution and diversification rather than regional differences in clade ages or immigration.</p> <p><b>Location: </b>EAS and ENA.</p> <p><b>Time period:</b> Current.</p> <p><b>Major taxa studied:</b> Plant taxa disjunctly distributed in EAS and ENA.</p> <p><b>Method:</b> We compiled county-level plant distribution data, and calculated species richness and variables of topography and climate within unit grid cells. We compared estimated coefficients of region effects among models, where richness was fitted with or without topography and climate. Topography and climate were also used to separately model within-region spatial diversity patterns using spatial simultaneous autoregressive error models.</p> <p><b>Results: </b>The coefficients of region effects varied from -0.776 for the model only including region to -0.309 when topography was controlled for, but remained significant. Climate dominated the spatial diversity patterns in ENA. In contrast, the influence of climate (14.2%) on species richness was weaker than that of topography (18.3%) in warm EAS. Relations to elevation and temperature varied between regions, shifting between positive and negative relationships in several cases.</p> <p><b>Main conclusion:</b> Our results demonstrate that variability in local topography contributes to the strong regional anomaly in plant species richness between EAS and ENA. Nevertheless, the diversity anomaly persists after controlling for local topography and climate. EAS and ENA also exhibit contrasting richness–environment relationships, providing another divergent aspect between the EAS-ENA disjunct floras. Our findings highlight that regional differences in topography or other environmental factors may underlie the diversity anomaly.</p>
Data from: Temporal and spatial comparisons of angiosperm diversity between eastern Asia and North America
<p>Eastern Asia (EA) and North America north of Mexico (NA) have comparable latitude, land area, and climate, but the overall plant diversity is much higher in EA than in NA. Despite intensive studies on disjunct taxa of the two regions, the temporal and spatial diversity patterns between the two floras remain unclear. Here we explore the floristic differences between EA and NA using the well-studied floras of China and the United States of America (USA) as exemplars, while also employing a newly generated dated phylogeny covering ~90% of the angiosperm genera of the two countries and comprehensive spatial distribution data. We find that China possesses both higher richness and phylogenetic diversity (PD) for angiosperm genera than the USA. Notably, most lineages contribute to the PD anomaly between the two floras, with 46 of 58 lineages having higher PD in China. Temporally, China has a higher proportion of genera that originated before the Miocene than are found in the USA (29.9% vs 23.2%). The eastern USA has more genera that originated during the Paleogene than does the western USA, but the reverse pattern is observed after the middle Miocene, with more genera originating in the west. Spatially, China shows a more distinct east-west deviation in diversity than the USA with eastern China possessing much higher generic richness and PD and more ancient lineages than western China. However, the eastern USA possesses lower generic richness, but higher PD and more ancient lineages than the western USA. Both the floras in China and the USA share a signature of an older east and a younger west, and this pattern may be largely driven by regional orogenic activities and climatic changes in the west of the two regions. Finally, our study indicates that more efforts are needed to enhance biodiversity conservation in southern China and the eastern USA by identifying and protecting phylogenetic diversity hotspots.</p>
