| Summary: | In the alpine landscape, characterized by high spatiotemporal heterogeneity and barriers, divergent selection is likely to lead to local adaptation of plant populations either through adaptive genetic differentiation or through phenotypic plasticity. The relative importance of these processes has rarely been investigated in relation to the spatial scale of environmental heterogeneity. In this study, we used reciprocal transplantation experiments of populations across nearby and distant field sites to shed light on these complementary processes. We reciprocally transplanted populations of the widespread alpine grass, Poa alpina, within and across regions in the Swiss Alps. We inferred local adaptation at the metapopulation level by comparing fitness of plants transplanted to their site of origin and to nearby or distant novel sites. Additionally, we measured specific leaf area (SLA) and performed selection analyses to investigate directional selection on mean trait value at each field site and on the degree ... : poa_alpina_dataThis file contains all raw data on the first sheet, with the site name, elevation of the site, site location (region in Switzerland), individual number (genotype_replicate clone), population name, origin of the population, sympatric vs. allopatric criterion (sympatric, near-allopatric, far-allopatric), initial tiller number (initial tiller), height of inflorescences (height), number of tillers (ntiller), number of inflorescences (nrepro), incidence of reproduction (repro), vegetative biomass (vegbiom), survival, reproductive biomass (reprobiom), and specific leaf are (sla). On the second sheet, you willl find the data for the selection analysis of plasticity at the small spatial scale (sympatric - near-allpoatric : SA), with the standardized plasticity index (stand_index), the standardized specific leaf area (stand_sla), and the relative fitness (relat-fit). Same for the third sheet, except with data calculted at the larger spatial scale (sympatric - far-allopatric: SF). IMPORTANT NOTE: The ... |
