Reproductive Transitions and Sperm Utilisation in a Facultatively Parthenogenetic Stick Insect [PDF]
Ecology and EvolutionFacultative parthenogenesis enables females to switch from asexual (parthenogenetic) to sexual reproduction after mating, but the process of fertilisation is poorly understood in such animals. In particular, it is not known whether switching reproductive

Parthenogenesis in dipterans: a genetic perspective.
, 2023 Parthenogenesis has been documented in almost every phylum of animals, and yet this phenomenon is largely understudied. It has particular importance in dipterans since some parthenogenetic species are also disease vectors and agricultural pests. Here, we

Exceptional long-term sperm storage by a female vertebrate.
PLoS ONE, 2021 Females of many vertebrate species have the capacity to store sperm within their reproductive tracts for prolonged periods of time. Termed long-term sperm storage, this phenomenon has many important physiological, ecological, and evolutionary ...

Parthenogenesis and the Evolution of Anisogamy
Cells, 2021 Recently, it was pointed out that classic models for the evolution of anisogamy do not take into account the possibility of parthenogenetic reproduction, even though sex is facultative in many relevant taxa (e.g., algae) that harbour both anisogamous and

Costs of parthenogenesis on growth and longevity in ex situ zebra sharks Stegostoma tigrinum
Endangered Species Research, 2023 The zebra shark Stegostoma tigrinum, a popular aquarium fish, is an endangered species that is known to readily reproduce both sexually and through facultative parthenogenesis while in human care.

Notes on court and copula, fertility, nest, eggs and hatchlings of the Caatinga’s black snake Boiruna sertaneja Zaher, 1996 (Serpentes: Dipsadidae) from northeastern Brazil [PDF]
Anais da Academia Brasileira de Ciências, 2020 The Caatinga’s black snake Boiruna sertaneja is a Pseudoboini species, endemic of the Caatinga biome. It is rare and fits in five traits that suggest it deserve more attention in reproduction research and conservation policies.

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