Asexual Reproduction in Holothurians [PDF]

open access: yesThe Scientific World Journal, 2014
Aspects of asexual reproduction in holothurians are discussed. Holothurians are significant as fishery and aquaculture items and have high commercial value.

ARP: asexual reproduction programming

open access: yesConnection Science, 2021
Recently meta-heuristic techniques have attracted more attention. Algorithms based on Bio-inspired problems are among the most popular techniques of this field. In meta-heuristic algorithms, Genetic algorithm is one of the most useful. GA uses chromosome

Identification of an innexin required for termination of the asexual state in planarian reproductive switching. [PDF]

open access: yesPLoS Genetics
Many metazoans switch between asexual and sexual reproduction based on environmental changes, life cycle phases, or both. This reproductive strategy enables them to benefit from the features of both reproductive modes. In general, asexual reproduction is

Is facultative sex the best of both worlds in the parasitoid wasp Lysiphlebus fabarum? [PDF]

open access: yesRoyal Society Open Science
The prevalence of sexual reproduction has long puzzled evolutionary biologists. This is because asexual parthenogenesis is a more efficient mode of reproduction, and all-else-being-equal, should predominate over sex.

Hybridization promotes asexual reproduction in Caenorhabditis nematodes.

open access: yesPLoS Genetics, 2019
Although most unicellular organisms reproduce asexually, most multicellular eukaryotes are obligately sexual. This implies that there are strong barriers that prevent the origin or maintenance of asexuality arising from an obligately sexual ancestor.

Evidence for stronger discrimination between conspecific and heterospecific mating partners in sexual vs. asexual female freshwater snails [PDF]

open access: yesPeerJ, 2022
Once-useful traits that no longer contribute to fitness tend to decay over time. Here, we address whether the expression of mating-related traits that increase the fitness of sexually reproducing individuals but are likely less useful or even costly to ...

Mitochondrial Genomes of Two Asexual Trichogramma (Hymenoptera: Trichogrammatidae) Strains and Comparison with Their Sexual Relatives

open access: yesInsects, 2022
Despite its substantial costs, sexual reproduction dominates in animals. One popular explanation for the paradox of sex is that asexual reproduction is more likely to accumulate deleterious mutations than sexual reproduction.

Influence of the mode of reproduction on dispersal evolution during species invasion [PDF]

open access: yesESAIM: Proceedings and Surveys, 2020
We consider a reaction-diffusion-reproduction equation, modeling a population which is spatially heterogeneous. The dispersion of each individuals is influenced by its phenotype.

Thelytokous parthenogenesis in the fungus-gardening ant Mycocepurus smithii (Hymenoptera: Formicidae). [PDF]

open access: yesPLoS ONE, 2009
The general prevalence of sexual reproduction over asexual reproduction among organisms testifies to the evolutionary benefits of recombination, such as accelerated adaptation to changing environments and elimination of deleterious mutations.

Transgenerational effects and temperature variation alter life history traits of the moon jellyfish

open access: yesFrontiers in Marine Science, 2022
Understanding the life history strategy of organisms is key to predicting their population dynamics. The population of scyphozoan jellyfish has displayed an increasing trend in recent decades, yet its life history strategy is not fully understood.
