Exploring the relationship between tychoparthenogenesis and inbreeding depression in the Desert Locust, Schistocerca gregaria [PDF]

open access: yes, 2017
Tychoparthenogenesis, a form of asexual reproduction in which a small proportion of unfertilized eggs can hatch spontaneously, could be an intermediate evolutionary link in the transition from sexual to parthenogenetic reproduction.

The Life Cycle Relative to Temperature of Protaphorura Armatus (Tullberg) (Collembola: Onychiuridae), a Parathenogenetic Species [PDF]

open access: yes, 2017
Apparent parthenogenetic reproduction in Collembola has sometimes been attributed to accidental transfer of spermatophores with the food material from one culture to another (Schaller, 1953; Mayer, 1957).

Convergent consequences of parthenogenesis on stick insect genomes

open access: yesbioRxiv, 2020
The shift from sexual reproduction to parthenogenesis has occurred repeatedly in animals, but how the loss of sex affects genome evolution remains poorly understood.

Transcriptome Analysis of Thermal Parthenogenesis of the Domesticated Silkworm. [PDF]

open access: yesPLoS ONE, 2015
Thermal induction of parthenogenesis (also known as thermal parthenogenesis) in silkworms is an important technique that has been used in artificial insemination, expansion of hybridization, transgenesis and sericultural production; however, the exact ...

The Role of HSA21 Encoded Mirna in Down Syndrome Pathophysiology:Opportunities in miRNA-Targeted Pharmacotherapy and Diagnosis of the Down Syndrome [PDF]

open access: yesPharmaceutical Sciences, 2021
Trisomy 21 is the most prevalent aneuploidy disorder among live-born children worldwide. Itresults from the presence of an extra copy of chromosome 21 which leads to a wide spectrum ofpathophysiological abnormalities and intellectual disabilities ...

Parthenogenesis in scorpions: some history - new data

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2008
Parthenogenesis, a rare phenomenon in Chelicerates, apart from mites, is reviewed in scorpions, notably Tityus serrulatus Lutz & Mello from Brazil, Tityus columbianus (Thorell) from Colombia and Tityus metuendus Pocock from Peru and Brazil.

Facultative parthenogenesis in the burrowing mayfly, Ephoron eophilum (Ephemeroptera: Polymitarcyidae) with an extremely short alate stage

open access: yesEuropean Journal of Entomology, 2015
Facultative parthenogenesis is important for mayflies with short alate stages because females are able to reproduce without mating. We studied facultative parthenogenesis in Ephoron eophilum, a mayfly with an extremely short alate stage.

Hybridisation generates a hopeful monster: a hermaphroditic selfing cichlid [PDF]

open access: yes, 2016
Compared to other phylogenetic groups, self-fertilization (selfing) is exceedingly rare in vertebrates and is known to occur only in one small clade of fishes.

Diversity in the reproductive modes of European Daphnia pulicaria deviates from the geographical parthenogenesis. [PDF]

open access: yesPLoS ONE, 2011
Multiple transitions to obligate parthenogenesis have occurred in the Daphnia pulex complex in North America. These newly formed asexual lineages are differentially distributed being found predominantly at high latitudes.

A comparative study on the functional response of Wolbachia-infected and uninfected forms of the parasitoid wasp Trichogramma brassicae [PDF]

open access: yes, 2010
Trichogramma species (Hymenoptera: Trichogrammatidae) are haplo-diploid egg parasitoids that are frequently used as biological control agents against lepidopteran pests.
