GENE FLOW AND SPECIATION. "Speciation in the presence of gene flow, in sexual species, can be driven by two general processes: (i) nonrandom mating that results in assortative mating, the mating of like with like, which reduces gene flow between groups, and (ii) divergent selection, which favors extremes in a population and thus can lead to a splitting of the species." https://lnkd.in/g9StYjV View in LinkedIn

DIOECIOUS TRAITS. "Recent large-scale molecular phylogenetic analyses confirm some of the correlations between dioecy and ecological traits and highlight the diversification of dioecious lineages associated with ecological features" such as woodiness, climber habit, and fleshy fruits. https://lnkd.in/g_fheyF View in LinkedIn

GENE FLOW PROMOTES COHESION. "One of the most intriguing aspects of speciation is how it might proceed under the most difficult of circumstances, namely in the face of gene flow. Gene flow poses an especially interesting problem for evolutionary theorists because it counters the forces driving differentiation between species, leading to continued cohesion across them." https://lnkd.in/g9StYjV View in LinkedIn

CHARACTERISTICS. "Dioecy has been correlated with plant spatial distribution, tropical floras, oceanic islands, and oligotrophic environments, and since Darwin (1877), resource allocation has been suggested as a causal factor in the evolution and maintenance of dioecy." https://lnkd.in/g_fheyF View in LinkedIn

GENE FLOW AND SPECIATION. "The role of gene flow during speciation and how it contributes to the emergence of islands of differentiation are key questions in speciation genomics." https://lnkd.in/gTNiFfV View in LinkedIn

GENE FLOW AND TIME. "Both time and low gene flow are the key factors by which different biological species arise. The divergence process among lineages and the development of pre- or postzygotic isolation occur when gene flow events are lacking." https://lnkd.in/gBACF7A View in LinkedIn

‪Is sexual dimorphism an occult type of speciation with different evolutionary trajectories?‬" "‪https://lnkd.in/gBNnsJm View in LinkedIn

SEX AS SPECIATION? "Therefore, when separate sexes evolve, constraints to gender specialization are relieved and the establishment of unisexuality is expected to be associated with sex-specific adaptation, particularly in reproductive traits." https://lnkd.in/ge7JD6J View in LinkedIn

BRANCHED ROAD. "When dioecy evolves from hermaphroditism, females and males are expected to diverge and specialize to their respective unisexual conditions. This is because hermaphroditic plants cannot be simultaneously optimized for both female and male function." https://lnkd.in/ge7JD6J View in LinkedIn

CONUNDRUM. "Among dioecious flowering plants, females and males often differ in a range of morphological, physiological, and life-history traits. This is referred to as sexual dimorphism, and understanding why it occurs is a central question in evolutionary biology." https://lnkd.in/ge7JD6J View in LinkedIn
