TLDR
An investigation of the range of diversity found in a single population of the obligate outbreeding species Trifolium repens L. in North Wales finds nearly every clone was found to differ significantly from every other clone in at least one character.Abstract:
SUMMARY (1) The results of an investigation of the range of diversity found in a single population of the obligate outbreeding species Trifolium repens L. in North Wales are presented, together with a consideration of the ways in which the variability uncovered may be maintained in the face of potential habitat dominance by a single successful genotype replicating rapidly through clonal growth. (2) The degree of variability found within this single population for a range of biochemical, morphological and phenological characters was of a magnitude more commonly encountered in comparisons between populations taken from distinctly different environments. Nearly every clone was found to differ significantly from every other clone in at least one character. (3) The applicability of the concept of sisyphean fitness, and the suggestion that the genotypes successful in the field are those which have achieved near-maximum fitness through an interaction of a momentarily effective combination of genes and the individual's history, are considered with respect to T. repens.read more

Patterns of Genotypic Diversity in Clonal Plant Species
TL;DR: The data from 27 studies show a common theme: multiclonal populations of intermediate diversity and evenness tend to be the rule, most clones are restricted to one or a few populations, and widespread clones are exceptional.

Seedling dynamics and life histories in clonal plants
TL;DR: On the basis of a hypothesized spectrum of variation in the extent clonal plants recruit by seedlings in established populations, predictions are made concerning clonal life histories, and structure and dynamics of genet populations.

Sex and evolution.
TL;DR: The relationship between various types of reproduction and the evolutionary process is explored, including the evolutionary development of diverse forms of sexuality, such as anisogamy, hermaphroditism, and the evolution of differences between males and females in reproductive strategy.
