Population dynamics with a mixed type of sexual and asexual reproduction in a fluctuating environment [PDF]
BMC Evolutionary Biology, 2012 Background Carassius gibelio, a cyprinid fish from Eurasia, has the ability to reproduce both sexually and asexually. This fish is also known as an invasive species which colonized almost all continental Europe, most likely originating from Asia and ...

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 strategies in the moon jellyfish Aurelia (Cnidaria: Scyphozoa) [PDF]
Frontiers 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 ...

Mating behavior of Pseudococcus calceolariae and Pseudococcus longispinus (Hemiptera: Pseudococcidae): are asexual reproduction and hybridization possible? [PDF]
J Insect Sci, 2023 The study of insect reproduction is important from both basic and applied perspectives, particularly in mealybugs (Hemiptera: Pseudococcidae), because of the diversity of reproduction modes and also because they are important agricultural pests.

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

Distinct patterns of gene expression during regeneration and asexual reproduction in the annelid Pristina leidyi. [PDF]
J Exp Zool B Mol Dev Evol, 2022 Regeneration, the ability to replace lost body parts, is a widespread phenomenon in the animal kingdom often connected to asexual reproduction or fission, since the only difference between the two appears to be the stimulus that triggers them.

Density, parasitism, and sexual reproduction are strongly correlated in lake Daphnia populations
Ecology and Evolution, 2021 Many organisms can reproduce both asexually and sexually. For cyclical parthenogens, periods of asexual reproduction are punctuated by bouts of sexual reproduction, and the shift from asexual to sexual reproduction has large impacts on fitness and ...

Scientific Reports, 2021 Asexual vertebrates are rare and at risk of extinction due to their restricted adaptability through the loss of genetic recombination. We explore the mechanisms behind the generation and maintenance of genetic diversity in triploid asexual (gynogenetic ...

Ciencias Marinas, 2013 This study addressed the relative contribution of sexual and asexual reproduction to the genetic composition of populations of two scleractinian corals, Pocillopora damicornis and Porites panamensis, off the west coast of mainland Mexico.
