| Zusammenfassung |
| The main processes underlying the generation and maintenance of biodiversity
include both local factors such as competition and abiotic filtering and
regional forces such as paleoclimate, speciation and dispersal. While the
effects of regional and local drivers on species diversity are increasingly
studied, their relative importance for other aspects of diversity, notably
phylogenetic and functional diversity is so far little studied. Here, we
link data from large Chinese forest plots to data on current and Last
Glacial Maximum (LGM) climate as well as local disturbance regimes to study
their relative roles in determining woody plant phylogenetic and functional
diversity in this important hotspot for woody plant diversity. Local
disturbance was the best predictor of functional diversity as represented by
maximum canopy height (Hmax), probably reflecting the dominant role of
competition for light in determining the forest Hmax structure. In
contrast, the LGM–present anomaly in temperature was the factor with the
strongest explanatory power for phylogenetic diversity, with modern climate
also important. Hence, local contemporary and regional historical factors
have highly contrasting importance for the geographic patterns of the
functional (as represented by variation in maximum canopy height) and
phylogenetic aspects of Chinese forest's woody plant diversity. Importantly,
contemporary factors are of overriding importance for functional diversity,
while paleoclimate has left a strong signature in the phylogenetic
diversity patterns. |
