Polyploidy has played an important role in angiosperm diversification, but how polyploidy contributes to reproductive isolation remains poorly understood. Most work has focused on postzygotic reproductive barriers, and the influence of ploidy differences on prezygotic barriers is understudied. To address these gaps, we quantified hybrid occurrence, interspecific self‐compatibility differences, and the contributions of multiple pre‐ and postzygotic barriers to reproductive isolation between… Expand
Habitat preference and flowering‐time variation contribute to reproductive isolation between diploid and autotetraploid Anacamptis pyramidalis
TLDR
Ecological divergence can strengthen the reproductive isolation between cytotypes, reducing the waste of gametes in low fitness interploidy crosses and thus favouring the initial establishment of the polyploid lineage. Expand
The role of multiple reproductive barriers: Strong post-pollination interactions govern cytotype isolation in a tetraploid-octoploid contact zone.
TLDR
The key role of gametic selection in cytotype siring success is revealed and the importance of comprehensive estimates across multiple reproductive barriers to understand cytotype interactions at contact zones is highlighted. Expand
Reproductive isolation and the maintenance of species boundaries in two serpentine endemic Jewelflowers
TLDR
Estimates of total reproductive isolation in S. breweri and S. hesperidis are robust to uncertainty and variability in individual barrier strength estimates, demonstrating how multiple barriers can act redundantly to prevent gene flow between close relatives living in sympatry. Expand
Ecological distributions, phenological isolation, and genetic structure in sympatric and parapatric populations of the Larrea tridentata polyploid complex.
TLDR
Diploid, tetraPloid, and hexaploid cytotypes of L. tridentata are segregated by environmental distributions and flowering phenology in contact zones, with diploid and tetraploid populations having corresponding differences in genetic structure. Expand
Strongly asymmetric hybridization barriers shape the origin of a new polyploid species and its hybrid ancestor.
TLDR
This study, which includes the first Mimulus chloroplast genome assembly, demonstrates the utility of parentage analysis through genome skimming and highlights the benefits of complementing genomic analyses with experimental approaches to understand asymmetry in allopolyploid speciation. Expand
Whole genome duplication does not promote common modes of reproductive isolation in Trifolium pratense.
TLDR
The results indicate that barriers other than the ones tested in this study-such as geographic isolation, vegetative reproduction, and pistil-stigma incompatibilities-may be more important in facilitating isolation and establishment of neopolyploid T. pratense. Expand
Strongly asymmetric hybridization barriers shape the origin of a new polyploid species and its hybrid ancestor
TLDR
There is strong evidence for asymmetric origins of M. peregrinus, but opposite to the common pattern, with paternal-excess crosses significantly more successful than maternal-excessive crosses. Expand
Differences in Floral Scent and Petal Reflectance Between Diploid and Tetraploid Chamerion angustifolium
Genome duplication in plants is thought to be a route to speciation due to cytotype incompatibility. However, to reduce cross-pollination between cytotypes in animal-pollinated species, distinctiveExpand
Assessing Water Use Variation Among the Cytotypes of the Autopolyploid Southwestern Desert Creosotebush (Larrea tridentata [DC.] COVILLE: ZYGOPHYLLACEAE)
TLDR
Results suggest that the cytotypes of the characteristic North American desert plant have similar water relationships, and possibly fitness outcomes, with respect to water use in common environments. Expand
Multiple reproductive barriers separate recently diverged sunflower ecotypes
TLDR
This article comprehensively test for reproductive isolation between recently diverged dune and nondune ecotypes of the prairie sunflower, Helianthus petiolaris, and finds reproductive barriers acting at multiple stages of hybridization, including premating, postmating–prezygotic, and postzyGotic barriers, despite the recent divergence.

Reproductive isolation between autotetraploids and their diploid progenitors in fireweed, Chamerion angustifolium (Onagraceae).
TLDR
Simulations indicated that the observed prezygotic isolation will reduce the strength of minority disadvantage acting on tetraploids and increase the importance of differences in viability and fertility between cytotypes in regulating polyploidy establishment. Expand
Reproductive isolation between diploid and tetraploid cytotypes of Libidibiaferrea (= Caesalpinia ferrea) (Leguminosae): ecological and taxonomic implications
TLDR
The reproductive biology of Libidibia ferrea is analysed to verify the degree of reproductive isolation between the two cytotypes, and data is discussed in relation to the establishment of polyploids, to the pattern of distribution of the species and to the taxonomic implications. Expand
Absence of pollinator-mediated premating barriers in mixed-ploidy populations of Gymnadenia conopsea s.l. (Orchidaceae)
TLDR
The absence of pre-mating barriers among cytotypes, except partial temporal segregation, suggests the existence of other mechanisms involved in the cytotypes’ coexistence, and demonstrated that the coexistence of Gymnadenia cytotypes in mixed-ploidy populations was only partly explained by differences in floral phenology. Expand
COMPONENTS OF REPRODUCTIVE ISOLATION BETWEEN THE MONKEYFLOWERS MIMULUS LEWISII AND M. CARDINALIS (PHRYMACEAE)
TLDR
The results suggest that ecological factors resulting from adaptive divergence are the primary isolating barriers in this system of Mimulus lewisii and M. cardinalis, sister species of monkeyflowers. Expand
Ecogeographic isolation: a reproductive barrier between species and between cytotypes in Houstonia (Rubiaceae)
TLDR
The hypothesis that ecogeographic isolation contributes to isolation of species and cytotypes within species of the plant genus Houstonia was tested and it was found that species in this group occupied significantly different niches, which suggests ecogeographical isolation is a contributing reproductive barrier.

TLDR
Empirical estimates of the relative importance of different barriers to gene flow between recently diverged species are important for understanding processes of speciation and suggest ecological factors contributed to speciation in this system and evolved before extensive intrinsic postzygotic isolation.

POLLINATOR‐MEDIATED REPRODUCTIVE ISOLATION AMONG DIOECIOUS FIG SPECIES (FICUS, MORACEAE)
The extent of isolation among closely related sympatric plant species engaged in obligate pollination mutualisms depends on the fitness consequences of interspecies floral visitation. In figsExpand
Spatial–temporal patterns of flowering asynchrony and pollinator fidelity in hybridizing species of Narcissus
TLDR
The finding that Hybrid formation between these species occurs only in sites where pollinator fidelity is incomplete suggests that hybrid formation also varies geographically and that divergent evolutionary outcomes may occur in different sympatric populations of Narcissus. Expand
Cytotype distribution at a diploid-tetraploid contact zone in Chamerion (Epilobium) angustifolium (Onagraceae).
TLDR
The results suggest that the zone of sympatry is best characterized as a mosaic rather than a cline, with diploid and tetraploids in close proximity and that the distribution of polyploidy is regulated by ecological sorting in a heterogeneous physical environment. Expand

TLDR
The effects of triploids on autotetraploid evolution is evaluated using computer simulations and by synthesizing research on the evolutionary dynamics of mixed-ploidy populations in Chamerion angustifolium (Onagraceae). Expand
