Patterns of gene expression in ovaries of sexual vs. asexual lineages of a freshwater snail

open access: yesFrontiers in Ecology and Evolution, 2022
Why sexual reproduction is so common when asexual reproduction should be much more efficient and less costly remains an open question in evolutionary biology.

Reproduction and Dispersal of Biological Soil Crust Organisms [PDF]

open access: yes, 2019
Biological soil crusts (BSCs) consist of a diverse and highly integrated community of organisms that effectively colonize and collectively stabilize soil surfaces.

Monte Carlo Simulations of Sexual Reproduction

open access: yes, 1996
Modifying the Redfield model of sexual reproduction and the Penna model of biological aging, we compare reproduction with and without recombination in age-structured populations.

On the asexual reproduction of Plagiochila pluma Steph. [PDF]

open access: yes, 1992
Four types of asexual reproduction in Plagiochila and the Plagiochilaceae are known: propagules, caducous leaves, gemmae and cladia. Plagiochila pluma Steph. has caducous leaves and teeth with regenerants.

Superclone Expansion, Long-Distance Clonal Dispersal and Local Genetic Structuring in the Coral Pocillopora damicornis Type β in Reunion Island, South Western Indian Ocean. [PDF]

open access: yesPLoS ONE, 2017
The scleractinian coral Pocillopora damicornis type β is known to present a mixed reproduction mode: through sexual reproduction, new genotypes are created, while asexual reproduction insures their propagation.

Asexual Reproduction in Infectious Diseases

open access: yes, 2009
Parasitic organisms in the strict sense (eukaryotes) represent a significant part of the general biodiversity which has been described and, with 179 species affecting people worldwide, are of relevance for mankind in particular. Contrary to the classical view, many of these species are clonal.

Mate limitation, recurrent epidemic outbreaks, and the coexistence of sexual and asexual plant parasites [PDF]

open access: yes, 2014
To date, relatively few studies have focused on the effects of sex on population dynamics. Previous models found that sexual reproduction may either dampen population fluctuations or accentuate population fluctuations, depending on mating system notably.

Low clonal propagation in Atlantic and Mediterranean populations of the red gorgonian Paramuricea clavata (Octocorallia) [PDF]

open access: yes, 2017
Clonal propagation is a common feature of benthic marine organisms. In the present study, we investigated the contribution of clonal reproduction in the red gorgonian Paramuricea clavata. Mediterranean populations of P.

Asexual reproduction strategies in the moon jellyfish Aurelia (Cnidaria: Scyphozoa)

open access: yesFrontiers in Ecology and Evolution, 2023
The genus Aurelia is one of the major contributors to jellyfish blooms in coastal waters, possibly due to its adaptive reproduction strategies. Different Aurelia lineages have adapted their reproduction modes to varying environmental conditions in their ...
