Molecular Ecology, Volume 34, Issue 16, August 2025.ABSTRACT Approximately, 40% of earthworm species can reproduce by parthenogenesis. This is the case for the cosmopolitan species, Aporrectodea trapezoides, although sexual forms have been described sporadically. We analyse the genotypes and microbiomes of 30 individuals from four localities where both forms appear in order to understand the ...

Gynogenesis caused by ultraviolet irradiation of salmonid sperm [PDF]
Journal of Experimental Zoology, 1982 AbstractGynogenetic rainbow trout lines can be produced easily with the simple UV sperm irradiation technique detailed in this study. The dose effect on embryonic survival rate is called a pseudo “Hertwig effect” because of major differences with results of gamma irradiation: Some mixing of various karyotypes (from diploid to haploid number) were ...

Asian Loaches: An Emerging Threat as Global Invaders
Freshwater Biology, Volume 70, Issue 4, April 2025.ABSTRACT The introduction of non‐native species is a major driver of biodiversity loss, posing a growing threat to the health and functioning of freshwater ecosystems globally. In recent decades, pet trade and aquarophilia have become lucrative industries, accelerating the introduction and spread of new non‐native fishes.

Environmental DNA, Volume 7, Issue 2, March/April 2025.ABSTRACT The ability to accurately detect harmful aquatic invasive species in a species‐specific manner is crucial to monitoring and management efforts. The Canadian province of Alberta currently harbors North America's only invasive Prussian Carp populations, in addition to invasive Goldfish populations.

Reviews in Aquaculture, Volume 17, Issue 2, March 2025.ABSTRACT Triploid fish are usually sterile, a trait which reduces unwanted sexual maturation in fish farming and eliminates the risk for negative genetic effects of escapees on wild stocks. The triploid state, normally established through a doubling of the maternal genome, consists of two chromosome sets from the mother and one from the father.

Effect of Media on Gynogenesis Induction in Leek (allium ampeloprasum L.) Breeding Materials
International Journal of Secondary Metabolite, 2016 Leek (Allium ampeloprasum L.) is one of the economically important members of the genus Allium (family:Alliaceae). It is a self-compatible, outbreeding, tetraploid (2n=4X= 32) crop species that is very difficult to improve through traditional breeding ...

Revista de la Facultad de Ciencias Agrarias, 2022 Doubled haploid onion (Allium cepa L.) plants allow the production of completely homozygous lines for a later production of hybrids. The haploid plants are normally produced using in vitro gynogenesis. The obtained haploid plantlets must be treated with
