How does the mode of evolutionary divergence affect reproductive isolation?

open access: yesPeer Community Journal, 2023
When divergent populations interbreed, the outcome will be affected by the genomic and phenotypic differences that they have accumulated. In this way, the mode of evolutionary divergence between populations may have predictable consequences for the ...

An unusual reproductive mode in Hypsiboas (Anura: Hylidae)

open access: yesZoologia (Curitiba), 2011
We report an unusual reproductive behavior of Hypsiboas pardalis (Spix, 1824). Species belonging to this genus usually are known to reproduce in lentic water bodies, with the development of exotrophic tadpoles.

Differential Methylation Patterns in Apomictic vs. Sexual Genotypes of the Diplosporous Grass Eragrostis curvula

open access: yesPlants, 2021
DNA methylation is an epigenetic mechanism by which a methyl group is added to a cytosine or an adenine. When located in a gene/regulatory sequence it may repress or de-repress genes, depending on the context and species.

Comparative transcriptional analysis of asexual and sexual morphs reveals possible mechanisms in reproductive polyphenism of the cotton aphid. [PDF]

open access: yesPLoS ONE, 2014
Aphids, the destructive insect pests in the agriculture, horticulture and forestry, are capable of reproducing asexually and sexually upon environmental change. However, the molecular basis of aphid reproductive mode switch remains an enigma.

Dopamine pathway characterization during the reproductive mode switch in the pea aphid

open access: yesPeer Community Journal, 2022
Aphids are major pests of most of the crops worldwide. Such a success is largely explained by the remarkable plasticity of their reproductive mode. They reproduce efficiently by viviparous parthenogenesis during spring and summer generating important ...

Different Selection Levels of Mitogenomes: New Insights into Species Differentiation of the Triops longicaudatus (LeConte, 1846) Complex (Branchiopoda: Notostraca)

open access: yesDiversity
Lineages of the Triops longicaudatus (LeConte, 1846) complex, originally endemic to the Americas, have been able to successfully colonize extreme environments such as temporary aquatic systems through shifts in their reproductive modes.
