Comparing and contrasting development and reproductive strategies in the pupal hyperparasitoids Lysibia nana and Gelis agilis (Hymenoptera: Ichneumonidae) [PDF]

open access: yes, 2007
In most animals, the optimal phenotype is determined by trade-offs in life-history traits. Here, I compare development and reproductive strategies in two species of solitary secondary hyperparasitoids, Lysibia nana and Gelis agilis, attacking pre-pupae ...

Artificial Insemination and Parthenogenesis in the Zebra Shark Stegostoma tigrinum

open access: yesFrontiers in Marine Science, 2022
Maintaining self-sustaining populations of zoo and aquarium collections can be challenged when natural reproduction fails within mixed-sex populations; however, reproductive success can sometimes be restored with the application of reproductive ...

The APMAP interactome reveals new modulators of APP processing and beta-amyloid production that are altered in Alzheimer’s disease

open access: yesActa Neuropathologica Communications, 2019
The adipocyte plasma membrane-associated protein APMAP is expressed in the brain where it associates with γ-secretase, a protease responsible for the generation of the amyloid-β peptides (Aβ) implicated in the pathogenesis of Alzheimer’s disease (AD). In

Mating has opposite effects on male and female sexually selected cuticular hydrocarbons [PDF]

open access: yes, 2020
In Drosophila serrata flies, there is female choice for male cuticular hydrocarbon (CHC) profiles and male choice for female CHC profiles. Furthermore, both males and females can alter their CHCs: when there is more opportunity for mating, males express ...

Transcriptomic and Functional Analyses of Phenotypic Plasticity in a Higher Termite, Macrotermes barneyi Light

open access: yesFrontiers in Genetics, 2019
Eusocial termites have a complex caste system, which leads to the division of labor. Previous studies offered some insight into the caste differentiation in lower termites; however, few studies were focusing on the molecular mechanisms of higher termites
