Most animals are male/female species and reproduce sexually. Variation in this pattern of reproduction has arisen many times during animal evolution, particularly in nematodes. Little is known about the evolutionary forces and constraints that influenced the origin of self-fertilization, for instance, a type of reproduction that seems to have evolved many times in the phylum Nematoda. Caenorhab...

Closely related sympatric species are expected to evolve strong species discrimination because of the reinforcement of mate preferences. Fitness costs of heterospecific matings are thought to be higher in females than in males, and females are therefore expected to show stronger species discrimination than males. Here, we investigated gender and species differences in sexual isolation in a symp...

The significance of introgression as an evolutionary force shaping natural populations is well established, especially in animal and plant systems. However, the abundance and size of introgression tracts, and to what degree interspecific gene flow is the result of adaptive processes, are largely unknown. In this study, we present medium coverage genomic data from species of the filamentous asco...

We examined the application and review materials of three calls (n=2,823) of a prestigious grant for personal research funding in a national full population of early career scientists awarded by the Netherlands Organization for Scientific Research (NWO). Results showed evidence of gender bias in application evaluations and success rates, as well as in language use in instructions and evaluation...

Despite efforts to increase participation in science, technology, engineering and math fields (STEM), the role of students’ perceptions of the social relevance of science in guiding their expectations to major in STEM remains largely unexplored. Though science education scholars predict that perceptions of social relevance likely matter equally for boys and girls, gender scholars suggest that t...

Stress response is associated with manifestations of various psychosomatic and psychiatric disorders. Hence, it is important to understand the underlying mechanisms that influence this association. Moreover, men and women tend to react differently with stress-both psychologically and biologically. These differences also need to be studied in order to have a better understanding in the gender di...

This article reviews findings from anthropology, psychology, and other disciplines about the role of biological factors in the development of sex differences in human behavior, including biological theories, the developmental course of sex differences, and the interaction of biological and cultural gendering processes at different ages. Current evidence suggests that major biological influences...

Plants are rich source of natural products used for centuries to cure various the plant-derived medicines are based upon the premise that they contain natural substances that can promote health and alleviate illness. Silver NPs represent material, which can be used as a potential antibacterial agent in medical applications and different commercial products due to its biological activity. Recent...
