Genomic consequences and selection efficacy in sympatric sexual versus asexual kelps

Frontiers in Marine Science, 2022
Genetic diversity can influence resilience and adaptative capacity of organisms to environmental change. Genetic diversity within populations is largely structured by reproduction, with the prevalence of asexual versus sexual reproduction often ...

Evolution of plant reproduction: from fusion and dispersal to interaction and communication [PDF]

, 2009
Based on the existing data concerning the evolution of the sexual reproduction, it is argued that the processes of sex differentiation and interactions play a key role in evolution. From the beginning environment and organism are unified.

Extreme genetic diversity in asexual grass thrips populations. [PDF]

, 2016
The continuous generation of genetic variation has been proposed as one of the main factors explaining the maintenance of sexual reproduction in nature.

Evolution of ethnocentrism on undirected and directed Barabási-Albert networks [PDF]

, 2009
Using Monte Carlo simulations, we study the evolution of contigent cooperation and ethnocentrism in the one-move game. Interactions and reproduction among computational agents are simulated on undirected and directed Barabási-\ud Albert (BA) networks. We

Comparative transcriptome analysis of two reproductive modes in Adiantum reniforme var. sinense targeted to explore possible mechanism of apogamy

BMC Genetics, 2019
Background Apogamy is a unique asexual reproduction in the ferns, in which somatic cells of gametophytes go through dedifferentiation and then differentiate into haploid sporophytes bypassing fertilization.

The role of sexual vs. asexual recruitment of Artemisia wudanica in transition zone habitats between inter-dune lowlands and active dunes in Inner Mongolia, China [PDF]

Solid Earth, 2016
Artemisia wudanica is an endemic, perennial, pioneering psammophyte species in the sand dune ecosystems of western Horqin Sand Land in northern China. However, no studies have addressed how sexual and asexual reproduction modes of A.

Sexual versus Asexual Reproduction: Distinct Outcomes in Relative Abundance of Parthenogenetic Mealybugs following Recent Colonization.

PLoS ONE, 2016
Asexual reproduction, including parthenogenesis in which embryos develop within a female without fertilization, is assumed to confer advantages over sexual reproduction, which includes a "cost of males." Sexual reproduction largely predominates in ...

Asexual reproduction: Genetics and evolutionary aspects

Cellular and Molecular Life Sciences, 2007
Reproduction is essential to all organisms if they are to contribute to the next generation. There are various means and ways of achieving this goal. This review focuses on the role of asexual reproduction for eukaryotic organisms and how its integration in a life cycle can influence their population genetics and evolution.

Reproductive Strategies of the Seagrass Zostera japonica Under Different Geographic Conditions in Northern China

Frontiers in Marine Science, 2020
Seagrasses form a unique group of submerged marine angiosperms capable of both sexual and asexual reproduction. The amounts of sexual and asexual reproduction differ within some species relying on geographic location and environmental factors.

Genetics of decayed sexual traits in a parasitoid wasp with endosymbiont-induced asexuality. [PDF]

, 2014
Trait decay may occur when selective pressures shift, owing to changes in environment or life style, rendering formerly adaptive traits non-functional or even maladaptive.
