Large-scale processes and the Asian bias in species diversity of temperate plants

  title={Large-scale processes and the Asian bias in species diversity of temperate plants},
  author={Hong Qian and Robert E. Ricklefs},
An important issue in the study of biodiversity is the extent to which global patterns of species richness reflect large-scale processes and historical contingencies. Ecological interactions in local assemblages may constrain the number of species that can coexist, but differences in diversity in similar habitats within different regions (diversity anomalies) suggest that this limit is not firm. Variation in rate of species production could influence regional and perhaps local diversity… 

Phylogenetic diversity anomaly in angiosperms between eastern Asia and eastern North America

Comparisons of biodiversity between regions that are currently ecologically similar but support different numbers of species are informed by considering differences in their geographic and evolutionary histories find that phylogenetic diversity in eastern Asia substantially exceeds that in eastern North America when controlling statistically for climate and species richness.

Geographic patterns of insect diversity across China's nature reserves: The roles of niche conservatism and range overlapping

The hump‐shaped latitudinal pattern of insect richness in China is mainly shaped by niche conservatism and range overlapping, supplemented by habitat heterogeneity and contemporary climate.

Temperature dependence, spatial scale, and tree species diversity in eastern Asia and North America

2 comparable databases of tree distributions in eastern Asia and North America are used to investigate the roles of environmental temperature and spatial scale in shaping geographical patterns of species diversity and find that number of species increases exponentially with environmental temperature, and so does the rate of spatial turnover in species composition.

Region effects influence local tree species diversity

It is shown that the species richness of forest trees varies among continental regions independently of local climate, with forest plots in Europe and North America contain fewer species than expected from the statistical relationship of diversity to present-day local climate.

Geographic patterns and environmental correlates of terrestrial mammal species richness in China.

It is suggested that patterns of mammal richness in China are governed by the integrated effects of different environmental predictors, with vegetation productivity playing a major role.

How tree species fill geographic and ecological space in eastern North America.

Eastern deciduous forests of North America do not appear to be saturated with species, and the distributions and abundances of individual species provide little evidence of being shaped by competition from related species, suggesting that diversification is constrained by interspecific competition.

Environmental causes for plant biodiversity gradients.

Within flowering plants (angiosperms), families exposed to a high energy load tend to be both more species rich and possess faster evolutionary rates, although there is no evidence that one drives the other.

Patterns, determinants and models of woody plant diversity in China

It is suggested that the patterns of woody species richness mainly result from the increasing intensity of frost filtering for tropical species from the equator/lowlands towards the poles/highlands, and hence support the freezing-tolerance hypothesis.

Beta diversity of angiosperms in temperate floras of eastern Asia and eastern North America

The diversity of a region reflects both local diversity and the turnover of species (beta diversity) between areas. The angiosperm flora of eastern Asia (EAS) is roughly twice as rich as that of

Effects of regional vs. ecological factors on plant species richness: an intercontinental analysis.

It is found that eastern Asia is richer than eastern North America when sample area, maximum elevation, and climate are accounted for, that this difference diminishes toward higher latitudes, and that elevation plays a much stronger role in eastern Asia than in eastern NorthAmerica.



Community Diversity: Relative Roles of Local and Regional Processes

Observations suggest that regional and historical processes, as well as unique events and circumstances, profoundly influence local community structure and ecologists must broaden their concepts of community processes and incorporate data from systematics, biogeography, and paleontology into analyses of ecological patterns and tests of community theory.

Energy and Large-Scale Patterns of Animal- and Plant-Species Richness

It is found that, in the four vertebrate classes studied, 80%-93% of the variability in species richness could be statistically explained by a monotonically increasing function of a single variable: annual potential evapotranspiration (PET).

Spatial Pattern of Vascular Plant Diversity in North America North of Mexico and its Floristic Relationship with Eurasia

Abstract This paper reports: (1) patterns of taxonomic richness of vascular plants in North America (north of Mexico), an area accounting for 16.6% of the total world land, in relation to latitudinal

Evolution of Eastern Asian and Eastern North American Disjunct Distributions in Flowering Plants

  • J. Wen
  • Environmental Science
  • 1999
Phylogenetic, molecular, geologic, and fossil data all support the hypothesis that the eastern Asian and eastern North American disjunct distributions are relicts of the maximum development of temperate forests in the northern hemisphere.

A Comparison of the Taxonomic Richness of Vascular Plants in China and the United States

The patterns of diversity of Chinese and U.S. vascular plants have been influenced by the longer and more open access of temperate eastern Asia to tropical regions, the presence in southern China of a larger area of subtropical climate with complex topography, and the reduced impact of late Tertiary climate cooling in eastern Asia compared to North America.

Some Aspects of Plant Geography of the Northern Hemisphere During the Late Cretaceous and Tertiary

Certain tentative conclusions can be drawn concerning ancient floristic relationships; combined with data derived from analyses of the present distribution of some angiosperm groups, hypotheses can be ventured, but many of these hypotheses require confirmation or rejection from future work.

Cladistic biogeography of Gleditsia (Leguminosae) based on ndhF and rpl16 chloroplast gene sequences.

Cl cladistic analysis of chloroplast gene sequences was used to test biogeographic hypotheses in the woody genus Gleditsia, finding that there is a fundamental division of the genus into three clades, only one of which contains both Asian and North American species.


It is inferred that Aesculus originated during the transition from the Cretaceous to the Tertiary (~65 M.Y.B.P.) at a high latitude in eastern Asia and spread into North America and Europe as an element of the “boreotropical flora”; the current disjunct distribution of the genus resulted from geological and climatic changes during theTertiary.
