Parthenogenesis in a captive Asian water dragon (Physignathus cocincinus) identified with novel microsatellites.

open access: yesPLoS ONE, 2019
Reptiles show varying degrees of facultative parthenogenesis. Here we use genetic methods to determine that an isolated, captive female Asian water dragon produced at least nine offspring via parthenogenesis. We identified microsatellites for the species

Hybridisation has shaped a recent radiation of grass-feeding aphids

open access: yesBMC Biology, 2023
Background Aphids are common crop pests. These insects reproduce by facultative parthenogenesis involving several rounds of clonal reproduction interspersed with an occasional sexual cycle.

Facultative parthenogenesis in the Ryukyu drywood termite Neotermes koshunensis

open access: yesScientific Reports, 2016
AbstractParthenogenesis is a relatively rare reproductive mode in nature compared to sex. In social insects, the evolution of parthenogenesis has a notable impact on their life histories. Some termites with parthenogenetic ability produce numerous non-dispersing supplementary queens asexually, whereas other castes are produced via sexual reproduction ...

Bacteriomes, cryptic forms and evolution of a common wireworm pest species, Hypnoidus bicolor

open access: yesInsect Molecular Biology, EarlyView.
Wireworms are important agricultural pests, including Hypnoidus bicolor in the Canadian Prairies. Parthenogenetic and sexual populations of H. bicolor appear associated with different molecular clades. Bacterial community composition and structure were influenced by developmental stage, sampling location and host genetics.

Determination of the Developmental Origin of Seeds Containing Endosperm Using Flow Cytometric Analysis

open access: yesBio-Protocol, 2015
Seeds derived from a diploid, sexual plant typically contain a 2n embryo (n+n) and 3n endosperm, a ratio characteristic for most flowering plants. However, this ratio is altered in apomictic species, which reproduce asexually through seeds (Koltunow and ...

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies

open access: yesJournal of Applied Entomology, Volume 150, Issue 7, Page 990-1015, August 2026.
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

Recurrent Alternate Parthenogenesis in the Common Smooth-Hound Shark (Mustelus mustelus) with Additional Cases and Further Evidence for a Putative Adaptive Reproductive Strategy

open access: yesAnimals
A new case of parthenogenesis in the common smooth-hound shark (Mustelus mustelus), recorded at the Cala Gonone Aquarium (central-eastern Sardinia, Italy) in April 2024, is described as an extension of previous observations.

First report of recurrent parthenogenesis as an adaptive reproductive strategy in the endangered common smooth-hound shark Mustelus mustelus

open access: yesScientific Reports
Parthenogenesis, or virgin birth, describes a mode of reproduction where an egg develops into an offspring without fertilization, and is observed across various vertebrate taxa, excluding mammals.
