ABSTRACT Female Drosophila melanogaster undergo a complex behavioral transformation following mating, characterized by increased sensory sensitivity and altered reproductive behaviors. In this study, we investigated the role of miR-9a, conserved microRNA, in regulating these post-mating changes. We found that miR-9a mutant females exhibited hypersensitivity phenotype, with rejection courting males, delayed onset sexual receptivity, abnormal mating termination behavior.

Abstract The features of the physical environment set stage upon which sexual selection operates, and consequently can have a significant impact on variation in realized individual fitness, influence population’s evolutionary trajectory. This phenomenon has been explored empirically several studies using fruit flies (Drosophila melanogaster) found that changing spatial complexity mating influenced male–female interaction dynamics, (re)mating rates, female fecundities. However, these did not explore patterns, dramatically alter genetic composition next generation, frequently only compared single, small “simple” to single larger “complex” environment. While shown broadly characteristics big effects reproductive plasticity this outcome more subtle changes extensively explored. Our study out compare patterns courtship between large- small-bodied males females, fecundities both simple 2 distinctly different spatially complex environments. We offspring production differed all 3 environments, indicating increasing outcomes are sensitive specific type environmental complexity. Furthermore, we observed were higher for environments those environment, supporting its role as mediator conflict. Together, results show union gametes within population be greatly by while some increased likely generalizable, other phenomena such rates may vary from one another.

Abstract The social-sexual environment is well known for its influence on the survival of organisms by modulating their reproductive output. However, whether it affects indirectly through a variety cues without physical contact and relative to direct interaction remain largely unknown. In this study, we investigated both indirect influences reproduction mite Tyrophagus curvipenis (Acari: Acaridae). results demonstrated no apparent conspecific mites, but mated female mites significantly changed, with females males having shortened lifespan increased lifetime fecundity. For males, significant difference was observed across treatments in lifespan. These findings indicate that opposite sex has much more profound than highlight urgent need expand research how modulate performance species clarify impacts taxa.
