How Do Tree Canopy and Soil Nutrients Drive Distinct Facets of Diversity and Community Assembly in Sub-Mediterranean Grasslands?
Question
How do tree canopy cover and soil nutrients shape the taxonomic, phylogenetic, and functional diversity of sub-Mediterranean grasslands?
Location
Valdebezana's valley (Burgos, Northern Spain).
Methods
We measured 10 above- and belowground plant functional raits related to resource acquisition strategies and dispersal ability from four sub-Mediterranean grasslands dominated by species with different biogeographic origins (Eurosiberian vs. Mediterranean). Then, we estimated patterns in taxonomic composition and compared the levels of taxonomic, phylogenetic, and functional diversity indices among communities and estimated their phylogenetic and functional assembly patterns, together with the decoupled functional diversity. Additionally, we estimated the influence of tree canopy and soil nutrients in shaping such patterns.
Results
Communities segregated according to their biogeographic origin (Eurosiberian vs. Mediterranean) along a soil resource gradient, matching the economics spectrum expectation. Taxonomic diversity differed significantly between biogeographic origins, but phylogenetic or functional diversity did not. Assembly patterns showed phylogenetic over-dispersion accompanied by functional clustering, with a significant effect of decoupling. Differences in taxonomic diversity were driven by edaphic factors, while canopy closure mainly influenced phylogenetic and functional patterns.
Conclusions
Sub-Mediterranean grasslands are highly rich in all facets of biodiversity (taxonomic, phylogenetic, and functional) and in assembly processes. In these habitats, local conditions may influence the structure and composition of herbaceous plant communities, highlighting the fragility of ecotones to environmental variations. Our results underline the need to develop proper management actions to preserve ecotone grassland communities; for instance, the creation of heterogeneous environments combining forest patches with open areas to maximize their biodiversity and functionality.
期刊介绍：
The Journal of Vegetation Science publishes papers on all aspects of plant community ecology, with particular emphasis on papers that develop new concepts or methods, test theory, identify general patterns, or that are otherwise likely to interest a broad international readership. Papers may focus on any aspect of vegetation science, e.g. community structure (including community assembly and plant functional types), biodiversity (including species richness and composition), spatial patterns (including plant geography and landscape ecology), temporal changes (including demography, community dynamics and palaeoecology) and processes (including ecophysiology), provided the focus is on increasing our understanding of plant communities. The Journal publishes papers on the ecology of a single species only if it plays a key role in structuring plant communities. Papers that apply ecological concepts, theories and methods to the vegetation management, conservation and restoration, and papers on vegetation survey should be directed to our associate journal, Applied Vegetation Science journal.
