Abstract

Among the traits whose relevance for plant invasions has recently been suggested are genome size (the amount of nuclear DNA) and ploidy level. So far, research on the role of genome size in invasiveness has been mostly based on indirect evidence by comparing species with different genome sizes, but how karyological traits influence competition at the intraspecific level remains unknown. We addressed these questions in a common‐garden experiment evaluating the outcome of direct intraspecific competition among 20 populations of Phragmites australis, represented by clones collected in North America and Europe, and differing in their status (native and invasive), genome size (small and large), and ploidy levels (tetraploid, hexaploid, or octoploid). Each clone was planted in competition with one of the others in all possible combinations with three replicates in 45‐L pots. Upon harvest, the identity of 21 shoots sampled per pot was revealed by flow cytometry and DNA analysis. Differences in performance were examined using relative proportions of shoots of each clone, ratios of their aboveground biomass, and relative yield total (RYT). The performance of the clones in competition primarily depended on the clone status (native vs. invasive). Measured in terms of shoot number or aboveground biomass, the strongest signal observed was that North American native clones always lost in competition to the other two groups. In addition, North American native clones were suppressed by European natives to a similar degree as by North American invasives. North American invasive clones had the largest average shoot biomass, but only by a limited, nonsignificant difference due to genome size. There was no effect of ploidy on competition. Since the North American invaders of European origin are able to outcompete the native North American clones, we suggest that their high competitiveness acts as an important driver in the early stages of their invasion.

Abstract

Analysing temporal patterns in plant communities is extremely important to quantify the extent and the consequences of ecological changes, especially considering the current biodiversity crisis. Long-term data collected through the regular sampling of permanent plots represent the most accurate resource to study ecological succession, analyse the stability of a community over time and understand the mechanisms driving vegetation change. We hereby present the LOng-Term Vegetation Sampling (LOTVS) initiative, a global collection of vegetation time-series derived from the regular monitoring of plant species in permanent plots. With 79 data sets from five continents and 7,789 vegetation time-series monitored for at least 6 years and mostly on an annual basis, LOTVS possibly represents the largest collection of temporally fine-grained vegetation time-series derived from permanent plots and made accessible to the research community. As such, it has an outstanding potential to support innovative research in the fields of vegetation science, plant ecology and temporal ecology., The authors acknowledge institutional support as follows.

Abstract

Differentiation within Phragmites australis, one of the world's most cosmopolitan and globally important wild plants, and invasions by individual lineages outside of their native ranges is attracting the interest of scientists worldwide. We compared the physiological performance of 89 populations representing distinct genotypes from six phylogcographic groups from Australia. Europe, North America (two groups including native and invasive populations introduced from Europe), South Africa and Far East in a common garden experiment. We show that the populations cluster into two distinct groups: one that includes populations from Europe and Far East together with the North American invasive, and the second the North American native populations with those from Australia and South Africa. Populations within the former group exhibited superior performance in the following traits: they were more vigorous in terms of higher shoot number per pot, greater belowground biomass, longer rhizomes, had greater specific leaf area (SLA), higher N and P concentrations in tissues, and greater investment into generative reproduction. Pooled across phylogcographic groups, P. australis has higher values of maximal photosynthesis (A(max)), higher N and P concentrations in tissues, and greater SLA than most vascular plants, represented by the GLOPNET dataset. Whether due to a weak environmental match or genetic differences, the results indicate that invasion by Australian and African populations in the Northern Hemisphere seems unlikely at present. However, it is not possible to exclude the invasion of genotypes of European origin into Southern Hemisphere or other temperate regions.
