• Premise of the study: Separating sexual function between different individuals carries risks,
especially for sedentary organisms. Nevertheless, many land plants have unisexual …

Sex chromosomes in land plants can evolve as a consequence of close linkage between the
two sex determination genes with complementary dominance required to establish stable …

Breeding systems are important, and often neglected, aspects of the natural biology of
organisms, affecting homozygosity and thus many aspects of their biology, including levels …

Baker's law refers to the tendency for species that establish on islands by long‐distance
dispersal to show an increased capacity for self‐fertilization because of the advantage of self …

This book takes a uniquely integrated approach to the study of floral biology. Flowers are the
beautiful and complex reproductive structures of the angiosperms, one of the most diverse …

Dioecy, the coexistence of separate male and female individuals in a population, is a rare
but phylogenetically widespread sexual system in flowering plants. While research has …

Colonization is likely to be more successful for species with an ability to self‐fertilize and
thus to establish new populations as single individuals. As a result, self‐compatibility should …

Phylogenetic relationships among 40 of the 43 recognized species of Fraxinus L.(Oleaceae)
were estimated on the basis of 106 nuclear ribosomal ITS sequences. ITS trees resulting …

Approximately 99.9% of vertebrate species reproduce sexually. The exceptional 0.1%
