Distinct geographic parthenogenesis in spite of niche conservatism and a single ploidy level: A case of Rubus ser. Glandulosi (Rosaceae)

Asexual organisms often differ in their geographic distributions from their sexual relatives. This phenomenon, termed geographic parthenogenesis, has long been in most taxa. Here, we present a new system of geographic

Diversity in the Reproductive Modes of European Daphnia pulicaria Deviates from the Geographical Parthenogenesis

Background: Multiple transitions to obligate parthenogenesis have occurred in the Daphnia pulex complex in North America. These newly formed asexual lineages are differentially distributed being found predominantly at high latitudes. This co...

Plant kleptomaniacs: geographical genetic patterns in the amphi-apomictic Rubus ser. Glandulosi (Rosaceae) reveal complex reticulate evolution of Eurasian brambles

of geographical parthenogenesis on a homoploid (2n = 4x) level. We aim to characterize the principal factor that established geographical parthenogenesis in R. ser. Glandulosi on the geographical differen...

Dysdera parthenogenetica sp. nov. (Araneae: Dysderidae), an unique case of parthenogenesis in spiders

An analysis of the species complex of Dysdera hungarica agg. spiders was carried out, part of which reproduces parthenogenetically. Relationships were established by comparing molecular and karyological markers. Distribution, habitat requirements and...

Negative effect of inbreeding on fitness of an arctic–alpine Hieracium alpinum (Asteraceae), a species with a geographical parthenogenesis distribution pattern

We found significant effects of inbreeding in two out of eleven measured traits in the F1 generation of Hieracium alpinum (Asteraceae). Initial biomass was statistically significantly lower by 9.6% in inbred lineages compared to outbred lineages. Sim...

The intriguing complexity of parthenogenesis inheritance in Pilosella rubra (Asteraceae, Lactuceae)

The study is focused on the inheritance of parthenogenesis in Pilosella tetraploid P.officinarum. The actual transmission rates of parthenogenesis were parthenogenesis was transmitted by female gametes. In n + 0 polyhaploid...

Making it on their own: sperm-dependent hybrid fishes (Cobitis) switch the sexual hosts and expand beyond the ranges of their original sperm donors

Interspecific hybridization may result in asexual hybrid lineages that reproduce via parthenogenesis. Contrary to true parthenogens, sperm-dependent asexuals. This suggests that sperm dependence is not as restrictive to geographical...
