    • The relationships between properties of present landscapes and species diversity within fragmented grasslands have been the subject of many studies. However the potential roles of grassland history and past landscape structure as determinants of diversity have not been widely studied. We therefore focus on these roles with an overview of patterns of variation in plant community composition in grassland fragments, of known ages, within a 22 km2 site around the village of Jordtorp on the Baltic island of Öland. While the frequencies of individual vascular plant species in 328 50 cm × 50 cm quadrats showed trends related to grassland continuity and previous land use, the dominant gradients of plant community composition were interpreted in terms of gradients of soil moisture and eutrophication. Because relationships between grassland age and plant community composition are confounded by local grassland eutrophication, it is difficult to use the present grassland data set to draw conclusions about the extent to which the distributions of individual species reflect a long history of continuous grassland management or an absence of eutrophication. Our results suggest that studies that attempt to explore associations between grassland age and fine-scale species richness, or the occurrence of individual species, should be based on sampling rules that standardize the type of plant community that is to be compared between grassland fragments.

  • A global meta-analysis of the relative extent of intraspecific trait variation in plant communities
  • 2015
  • Ingår i: Ecology Letters. - : Wiley. - 1461-023X .- 1461-0248. ; 18:12, s. 1406-1419

    • Recent studies have shown that accounting for intraspecific trait variation (ITV) may better address major questions in community ecology. However, a general picture of the relative extent of ITV compared to interspecific trait variation in plant communities is still missing. Here, we conducted a meta-analysis of the relative extent of ITV within and among plant communities worldwide, using a data set encompassing 629 communities (plots) and 36 functional traits. Overall, ITV accounted for 25% of the total trait variation within communities and 32% of the total trait variation among communities on average. The relative extent of ITV tended to be greater for whole-plant (e.g. plant height) vs. organ-level traits and for leaf chemical (e.g. leaf N and P concentration) vs. leaf morphological (e.g. leaf area and thickness) traits. The relative amount of ITV decreased with increasing species richness and spatial extent, but did not vary with plant growth form or climate. These results highlight global patterns in the relative importance of ITV in plant communities, providing practical guidelines for when researchers should include ITV in trait-based community and ecosystem studies.
