Sexual conflict as a constraint on asexual reproduction: an empirical review. [PDF]
Biol Rev Camb Philos SocABSTRACT Theory predicts that facultatively asexual animals, which can leverage the advantages of both sexual and asexual reproduction, should outcompete obligately sexual and obligately asexual animals. Yet, paradoxically, obligate sexual reproduction predominates in many animal lineages, while the most flexible form of facultative asexuality (i.e ...

Diet-Induced Developmental and Morphological Plasticity in a Thelytokous Predatory Mite <i>Amblyseius herbicolus</i> (Chant) (Acari: Phytoseiidae). [PDF]
Ecol EvolThis study investigated how variation in prey consumption influences immature development and adult morphometric traits in the predatory mite Amblyseius herbicolus. Mites that ate more prey attained a larger size at maturity but did not develop more rapidly. Several morphometric traits were also significantly influenced by diet.

Genetic evidence for parthenogenesis in the small carpenter bee Ceratina dallatoreana (Apidae, Ceratinini) in its native distribution range [PDF]
Journal of Hymenoptera Research, 2023 Arrhenotoky is the typical mode of reproduction in Hymenoptera. Diploid females develop from fertilized eggs, whereas haploid males originate from unfertilized eggs.

No Mate, No Problem: Molecular Mechanisms Involved in Parthenogenesis in the Cosmopolitan Earthworm Aporrectodea trapezoides (Annelida, Clitellata). [PDF]
Mol EcolABSTRACT 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 ...

Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect. [PDF]
Ecol EvolFacultative parthenogenesis enables females to switch from asexual (parthenogenetic) to sexual reproduction after mating, but the process of fertilisation is poorly understood in such animals. It is unknown whether switching reproductive modes requires changes in the eggs themselves, delaying the transition from laying unfertilised to fertilised eggs ...

Evaluation of asexual Wolbachia-infected Trichogramma brassicae performance in greenhouse and field conditions [PDF]
نامه انجمن حشرهشناسی ایران, 2023 In some Trichogramma species, parthenogenesis is mostly induced by intracellular symbiotic Wolbachia bacteria. Populations of this egg parasitoid wasp that produce more female progeny can potentially have higher fitness.

Comprehensive analysis of male-free reproduction in Monomorium triviale (Formicidae: Myrmicinae).
PLoS ONE, 2021 We report comprehensive evidence for obligatory thelytokous parthenogenesis in an ant Monomorium triviale. This species is characterized by distinct queen-worker dimorphism with strict reproductive division of labor: queens produce both workers and new ...

Thelytokous parthenogenesis and its consequences on inbreeding in an ant [PDF]
Heredity, 2006 Thelytokous parthenogenesis, that is, the production of diploid daughters from unfertilized eggs, may involve various cytological mechanisms, each having a different impact on the genetic structure of populations. Here, we determined the cytological mechanism of thelytokous parthenogenesis and its impact on inbreeding in the ant Cataglyphis cursor, a ...

What mechanistic factors affect thelytokous parthenogenesis in Apis mellifera caponises queens? [PDF]
Apidologie, 2020 The Cape honey bee (Capensis) is unusual in that workers can produce viable female offspring via thelytokous parthenogenesis. In contrast, mated queens never reproduce thelytokously, even though they could benefit from doing so when generating daughter queens.
