Experimental Evolution Induced by Maternal Post-copulatory Factors in Drosophila.

Article Synopsis
- • A study investigated how a sex pheromone (cis-vaccenyl acetate or cVa) transferred to eggs by female flies affected male behavior and pheromone release, depending on whether the eggs were exposed to maternal factors 1 day or 5 days after mating.
- • By observing these effects over 40 generations, the research found significant differences in reproductive traits, survival, and gene expression between flies exposed to maternal factors at different times, suggesting these maternal influences can shape adult characteristics.
Uterus histomorphometry of alpacas () in induced luteal phase, with GnRH or copulation.

Information and Education Center for the Prevention of Drug Abuse - CEDRO, Lima, Peru.
Article Synopsis
- Alpacas exhibit unique reproductive traits, including induced ovulation and differences in uterine horn gestation rates, but challenges like low fertility and high embryonic mortality persist, prompting further study of the uterine wall changes during the luteal phase.
- The research aimed to investigate histological changes in the uterine wall of alpacas, analyzing samples from both left and right uterine horns after inducing ovulation via GnRH or natural mating.
- Results indicated that copulation (G2) led to thicker uterine layers and larger gland areas in the left horn, suggesting better developmental conditions during the luteal phase, and highlighting new insights into alpaca reproductive physiology.
Mating-induced release of oxytocin in the mouse lateral septum: Implications for social fear extinction.

In mammals, some physiological conditions are associated with the high brain oxytocin (OXT) system activity. These include lactation in females and mating in males and females, both of which have been linked to reduced stress responsiveness and anxiolysis. Also, in a murine model of social fear conditioning (SFC), enhanced brain OXT signaling in lactating mice, specifically in the lateral septum (LS), was reported to underlie reduced social fear expression.

We used histological and morphometric methods to study the testis and associated glands, including the epididymis, ductus deferens, and renal sexual segment (RSS), of specimens of Basiliscus vittatus sampled from Tabasco, Mexico (17.5926° N, 92.5816° W).

Connectomics research has made it more feasible to explore how neural circuits can generate multiple outputs. Female sexual drive provides a good model for understanding reversible, long-term functional changes in motivational circuits. After emerging, female flies avoid male courtship, but they become sexually receptive over 2 d.
