1 According to ‘Gause's hypothesis’ a corollary of the process of evolution by natural selection is that in a community at equilibrium every species must occupy a different niche. Many botanists have found this idea improbable because they have ignored the processes of regeneration in plant communities. 2 Most plant communities are longer‐lived than their constituent individual plants. When an individual dies, it may or may not be replaced by an individual of the same species. It is this… 
Plant species coexistence - the role of historical, evolutionary and ecological factors
None of seven existing theories seeking to explain the coexistence of plant species, could singly explain the pattern of species richness found e.g. in calcicolous grasslands. A more general
THE USEFULNESS OF ECOLOGICAL NICHE CONCEPTS IN UNDERSTANDING PLANT COMMUNITIES
TLDR
Although it is unlikely that niche separation along environmental axes is the only mechanism of coexistence in any large community, the evidence now suggests that ecological niche concept plays a more significant role than has been previously appreciated.
Development of Species Diversity in Some Mediterranean Plant Communities
TLDR
Several mechanisms that contribute to the maintenance or to the modification of species diversity, act in different communities, during an ecological succession, and in forest communities throughout the year are investigated.
Effect of Seed Predation on Plant Regeneration: Evidence from Pacific Basin Mediterranean Scrub Communities
TLDR
Many contemporary environmental issues, including maintenance of biodiversity, sustainable use of natural systems, and rehabilitation of damaged ecosystems, require understanding of the processes that define and limit the performance of the characteristic, less common species.
Coexistence of plant species with similar niches
TLDR
A model based on the dynamics of species turnover in microsites, and incorporates localized competition, non-uniform seed dispersal and aspects of spatiotemporal environmental heterogeneity allow stable coexistence of trophically equivalent species.
Seed germination niche across habitats: an introduction to this special issue
TLDR
In this special issue of Folia Geobotanica, a series of papers about seed responses to environmental drivers across different vegetation types in North and South America, Europe, Asia, and Australia are presented.
Effect of gap size and regeneration niche on species coexistence in bryophyte communities
TLDR
The interaction of the regeneration niche and the disturbance regime are found to be primary determinants of community structure on this unstable substrate.

The role of plant interactions in the restoration of degraded ecosystems: a meta‐analysis across life‐forms and ecosystems
TLDR
Whereas restoring herbaceous communities seems largely reliable on removal techniques, augmenting populations of nurse shrubs and trees should be considered a promising strategy for restoring woody late-successional communities.
Biodiversity and plant productivity in a model assemblage of plant species
TLDR
Productivity as a function of biotic diversity was examined and showed that species-poor assemblages had wider ranges of possible productivities than more diverse assemblage.

Dominance and Diversity in Land Plant Communities
TLDR
Curves of decreasing productivity connect the few most important species with a larger number of species of intermediate importance and a smaller number of rare species, believed to express different patterns of competition and niche differentiation in communities.
Mutual Influences Between Plants, Allelopathy, Competition and Vegetation Changes
TLDR
In vegetation the environmental factors act mostly not directly on the individuals of a plant taxon; their effects are more or less modified by mutual influences between the plants.
Adaptation to Habitat in a Group of Annual Plants
TLDR
This work represents an attempt to investigate experimentally, using relatively simple apparatus, the basis of adaptation to a rather extreme habitat in a well-defined group of annuals on the Derbyshire limestone.
Adaptive Radiation of Reproductive Characteristics in Angiosperms, II: Seeds and Seedlings
TLDR
An exploratory review of characteristics of seeds and seedlings and of their relationship to the genotype-environment interactions that take place between the termination of flowering and the successful establishment of the next generation of seedlings is intended.
Competitive Exclusion in Herbaceous Vegetation
IN maintaining or reconstructing types of herbaceous vegetation in which the density of flowering plants exceeds 20 species/m2—the so-called “species-rich” communities, success is often frustrated by
Adaptive Radiation of Reproductive Characteristics in Angiosperms, I: Pollination Mechanisms
TLDR
In angiosperms, the adaptive significance of differences between most higher categories, as well as between a large proportion of related species, is most probably associated with reproductive efficiency and successful establishment of seedlings rather than with any of the morphological characteristics of the vegetative parts.
Plant Competition Mediated by Host-Specific Parasites-a Simple Model
It is suggested that competing co-dominant species in natural ecosystems may be maintained in equilibrium by an ecological, negative feedback system involving reciprocal, host-specific parasites. A
Competition and Diversity in Herbaceous Vegetation
GRIME1 points out that herbaceous vegetation on highly favourable, “low-stress” sites often contains few species compared with that on intermediate-stress sites. He proposes an explanation for this
