The complex causality of geographical parthenogenesis.
Asexual organisms usually have larger and more northern distributions than their sexual relatives. This phenomenon, called geographical parthenogenesis, has been controversially attributed to predispositions in certain taxa; advantages of polyploidy and/or hybrid origin; better colonizing abilities because of uniparental reproduction; introgression of apomixis into sexuals; niche differentiatio...
متن کاملReconstructing geographical parthenogenesis: effects of niche differentiation and reproductive mode on Holocene range expansion of an alpine plant.
Asexual taxa often have larger ranges than their sexual progenitors, particularly in areas affected by Pleistocene glaciations. The reasons given for this 'geographical parthenogenesis' are contentious, with expansion of the ecological niche or colonisation advantages of uniparental reproduction assumed most important in case of plants. Here, we parameterized a spread model for the alpine butte...
متن کاملFactors Related to Cultural Divergence in the Social Values among Two Generations of Families in Tehran
Cultural divergence is incongruity in the values, attitudes and behaviors among different generations of a society. Identifying factors related to cultural divergence in the social values of parents and children is one of the most important issues in Iranian society, which has been investigated in the present research through a quantitative approach. The statistical population of the study co...
متن کاملNiche partitioning among sexual and unisexual Ambystoma salamanders
Organisms that have ecologically similar sexual and asexual forms present an evolutionary puzzle, as theory predicts that eventually one form should eliminate the other. However, both forms may persist if there is niche partitioning between them. Geographical parthenogenesis is a hypothesis that predicts that in terms of niche use the asexual form in such pairs should be more ecologically succe...
متن کاملNiche divergence between diploid and autotetraploid Tolmiea.
PREMISE OF STUDY Polyploidy is common in eukaryotes and is of major evolutionary importance over both short and long time-scales. Compared to allopolyploids, autopolyploids remain understudied; they are often morphologically cryptic and frequently remain taxonomically unrecognized, although there is increasing recognition of the high frequency of autopolyploidy in angiosperms. While autopolyplo...
