Niche partitioning among sexual and unisexual Ambystoma salamanders
Ecosphere, 2016 Organisms that have ecologically similar sexual and asexual forms present an evolutionary puzzle, as theory predicts that eventually one form should eliminate the other.

Attempted Induction of Gynogenesis in Chickens
Poultry Science, 1975 Dark Cornish and White Leghorn hens were divided into a virgin group and a group inseminated with semen that had been irradiated with 5,000r. of X rays. Two replicate trials were performed, one during winter and the second during summer. Two parthenogenetic embryos were found among 1,417 virgin eggs incubated for 24 hours. No other development was seen

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 ...

Овощи России, 2015 The role of plant extracts in the process of induction of embryogenic structures and its following development in plants is revealed. Thus, the addition in the culture medium of the extracts diluted in DMSO increases the rate of gynoand androgenesis on 2.

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.

Efficiency of the use for doubled haploids in onion breeding (Allium cepa L.)
Овощи России, 2022 Relevance. In onion breeding, quickly obtain aligned material is an urgent target for create parent forms of heterosis hybrids. Using classical methods with helping of backcrosses, this is achieved in 10-12 years. Using the technology of doubled haploids,

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.
