Reproductive plasticity in freshwater invader: from long-term sperm storage to parthenogenesis. [PDF]

open access: yesPLoS ONE, 2013
Orconectes limosus, a North American crayfish species, is one of the most important aquatic invaders in European inland waters. Despite more than 120 years occurrence in Europe and intense research, there are still gaps in knowledge of its life history ...

Chromosome-level genome assembly and annotation of two lineages of the ant Cataglyphis hispanica: stepping stones towards genomic studies of hybridogenesis and thermal adaptation in desert ants

open access: yesPeer Community Journal, 2022
Cataglyphis are thermophilic ants that forage during the day when temperatures are highest and sometimes close to their critical thermal limit.

Fisher vs. the Worms: Extraordinary Sex Ratios in Nematodes and the Mechanisms that Produce Them

open access: yesCells, 2021
Parker, Baker, and Smith provided the first robust theory explaining why anisogamy evolves in parallel in multicellular organisms. Anisogamy sets the stage for the emergence of separate sexes, and for another phenomenon with which Parker is associated ...

Virgin Birth: A genetic basis for facultative parthenogenesis

open access: yes, 2022
Abstract Sexual reproduction evolved 1-2 billion years ago and underlies the biodiversity of our planet. Nevertheless, devolution of sexual into asexual reproduction can occur across all phyla of the animal kingdom. The genetic basis for how parthenogenesis can arise is completely unknown.

Sex at the margins: parthenogenesis vs. facultative and obligate sex in a Neotropical ant [PDF]

open access: yesJournal of Evolutionary Biology, 2012
AbstractGeographic parthenogenesis is a distribution pattern, in which parthenogenetic populations tend to live in marginal habitats, at higher latitudes and altitudes and island‐like habitats compared with the sexual forms. The facultatively parthenogenetic ant Platythyrea punctata is thought to exhibit this general pattern throughout its wide range ...

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.
