Optimizing the carbon‐to‐nitrogen ratio in biofloc technology enhances growth performance, reproductive output, and nutritional quality of the brine shrimp A. parthenogenetica

open access: yesJournal of the World Aquaculture Society, Volume 57, Issue 5, October 2026.
Abstract This study evaluated the effects of dietary carbon‐to‐nitrogen (C/N) conditions, generated by combining Dunaliella salina with sugar beet raffinate, on the growth, survival, reproductive performance, biochemical composition, fatty‐acid profile, digestive enzyme activity, microbial community, and biomass production of Artemia parthenogenitica ...

Spontaneous Parthenogenesis in a Fish [PDF]

open access: yesNature, 1953
THE guppy, Lebistes reticulatus, is a viviparous fish the reproductive physiology of which has been well studied (bibliography in Gordon1). A female, D9, of English domestic stock of this species born October 5, 1950, was separated from adult males twelve days after birth.

Genetic structure, spectral characteristics and evolutionary history of butterflies in the European Polyommatus eros species group (Lepidoptera, Lycaenidae)

open access: yesSystematic Entomology, Volume 51, Issue 4, October‐December 2026.
The genetic results, microbial (Wolbachia) screening and wing spectral characteristics suggested a close relationship between European taxa of the Polyommatus eros species group. Two lineages appear to be undergoing accelerated differentiation, in particular the endangered taxon menelaos, which is differentiated in both genetic and wing spectral ...

High-fat-diet impaired mitochondrial function of cumulus cells but improved the efficiency of parthenogenetic embryonic quality in mice

open access: yesAnimal Cells and Systems, 2018
Global human health has been compromised by high-fat diets. This study aimed to investigate the relationship between a high-fat diet and parthenogenetic embryo quality.

Contagious parthenogenesis, automixis, and a sex determination meltdown

open access: yes, 2010
Because of the twofold cost of sex, genes conferring asexual reproduction are expected to spread rapidly in sexual populations. However, in reality this simple prediction is often confounded by several complications observed in natural systems. Motivated

Geographic parthenogenesis: recurrent patterns down under.

open access: yes, 2006
A recent study reports striking similarities in the origin and spread of parthenogenesis in two distantly related animals of the Australian arid zone, suggesting that the loss of sex was driven by a very general selective ...
