Introduction And Objective: The common tick is one of Europe's most important vectors of tick-borne diseases. The increased risk of attacks by this tick suggests the need for identification of factors contributing to the transmission of tick-borne pathogens, and the routes of pathogen circulation in nature.
Material And Methods: Polymerase chain reaction was used to investigate the prevalence of four pathogens, i.e. s.l. (Bb), (Ap), spp. (Bs), and spp. (Ba) in females and males mating on dogs in south-central Poland.
Results: The study revealed the presence of three pathogens: Bb, Ap, and Bs in 9.4%, 5.4%, and 5.4% of all adults , respectively. Co-infection with two pathogens was detected in one tick specimen. spirochetes were isolated in two females and two males , but the sexual transfer of the spirochetes between these specimens could not be clearly confirmed.
Conclusions: By increasing the feeding dynamics in females, the copulation of males with females attached to the host's skin may stimulate pathogen replication in tick tissues and migration from the gut to the salivary glands. Further investigations of the copulation on the host on female feeding and pathogen transmission may contribute to the elucidation of the eco-epidemiology of tick-borne diseases transmitted by this tick species.

Background: Although some studies have revealed the close relationship between leptin and premature ejaculation in clinical practice, whether and how leptin participates in the regulation of ejaculatory behaviors are still unknown.
Objective: To explore the role of leptin on ejaculatory behaviors and its underlying mechanism.
Materials And Methods: Copulation behavior tests were performed after acute and chronic leptin administration at peripheral and central levels.

Mate availability and social information can influence mating behaviour in both males and females. Social information obtained from conspecifics can influence mate choice, particularly shown by studies on mate choice copying. However, the role of directly observing conspecific mating on mating behaviour has been less explored.

The pubertal phase involves significant brain reorganization, where external stressors and diet can profoundly influence long-term behavioral outcomes. In this study, we investigated the interaction between acute pubertal stress (via immune challenge) and a hypercaloric diet in adulthood on the copulatory sexual behavior of male Wistar rats. At postnatal day (PND) 35, pubertal males received a single injection of lipopolysaccharide (LPS, 1.

It occurs as a repeated alternation between copulation and mate-guarding, leading to the prolonged physical attachment between males and females. Particularly, in species where males forcefully grasp females, attempt to mate without courtship and exhibit repeated copulations, male and female morphological traits are expected to be associated with mating characteristics.

The bewildering courtship phenotypes of male birds of paradise () represent a classic example of sexual selection through mate choice. While the majority of sexual selection studies have focused on either mate choice or intrasexual competition, males across a variety of taxa adopt alternative mating tactics as additional means of obtaining fertilization when they are otherwise unable to. For example, across various polygynous birds, subordinate males engage in sneak copulations, which may offset the fitness costs of prolonged subordinate periods.
