INVASIBILITY AND SPECIES RICHNESS OF A COMMUNITY: A NEUTRAL MODEL AND A SURVEY OF PUBLISHED DATA
Unless more evidence is available to refute it, the relationship between native and alien species richness should be considered a result of a neutral processes due to constraints on the number of individuals in the community.
Seed, dispersal, microsite, habitat and recruitment limitation: identification of terms and concepts in studies of limitations
Sowing experiments, i.e. seed addition into existing populations or seed introduction into unoccupied habitats, are the only reliable types of evidence for the different types of limitations.
The most species-rich plant communities in the Czech Republicand Slovakia (with new world records)
We provide an inventory of the sites and vegetation types in the Czech Republic and Slovakia that contain the highest numbers of vascular plant species in small areas of up to 625 m2. The highest…
Ant-induced soil modification and its effect on plant below-ground biomass
It is proposed that differences found between the soil of nests and control plots are entirely a product of ant activity during mound occupancy and not due to initial soil differences during nest establishment, which has been less reported on in ant-soil studies.
Identification of suitable unoccupied habitats in metapopulation studies using co-occurrence of species
This study proposed a new quantitative technique to identify suitable but unoccupied habitats for metapopulation studies in plants. It is based on species composition at the habitat and knowledge of…
Community assembly by limiting similarity vs. competitive hierarchies: Testing the consequences of dispersion of individual traits
In conclusion, inference of community assembly processes from patterns of trait dispersion without understanding how particular traits function in community assembly may often be misleading.
Long‐term spatial dynamics of Succisa pratensis in a changing rural landscape: linking dynamical modelling with historical maps
This approach shows that the wealth of landscape information available from historical maps can be linked with data on population biology by means of dynamical models that can make predictions about species dynamics.
Vegetation changes following sheep grazing in abandoned mountain meadows

. Sheep grazing was investigated as an alternative to traditional management of meadows in the Krkonose Mts. Until the second World War these meadows were mown in mid-summer and grazed by cattle for…
Geometrical constraints in the scaling relationships between genome size, cell size and cell cycle length in herbaceous plants

The matches found for the relationships between GS and both cell size and S phase duration are signatures of geometrical scaling, and it is proposed that a similar approach can be used to examine GS effects at tissue and whole plant levels.
Fine-scale dynamics of rhizomes in a grassland community
Differences in rhizome growth parameters underlie different strategies of horizontal growth and dieback between species and can serve as one of the mechanisms of species replacements and contribute to the finescale coexistence of species.
