“…Introduction The reproductive behavior of animals plays an important role in reproduction, affecting both the success of mating and the survival of the offspring [1,2,3]. Various patterns of sexual behavior have been described for many animals, such as mammals [4,5,6] and livestock [7]. All patterns of sexual behavior arise in the course of evolution; they are in uenced by genetic, physiological, and environmental factors, as well as previous individual experiences.…”

BackgroundThere are several mechanisms of species isolation and species conservation, one of which is the behavior of individuals during the mating season. Inter specific hybridization is used to create new breeding forms and breeds of farm animals. The aim of this study was to look into the reproductive behavior of males of cultured sheep breeds and their wild relatives during the mating period in order to identify consistent patterns of movements, elementary motor acts, and individual reactions.ResultsIt was found that the duration of the courtship display in the European mouflon was, with a high degree of confidence, longer than in the male domestic sheep. In mouflons, it was 246.5 ± 31.85 minutes, while in rams, it was 88.46 ± 9.23 minutes (p < 0.0001). Many patterns in purebred sheep were shorter, or absent. In wild species, there is a connection between sexual activity and time of day. The highest frequency of intromission in mouflons occurred in the time interval between 6–8 a.m. and 11 p.m.–4 a.m.; in rams, the dependence of sexual activity on the time of day was not observed. During the estrus period, the relationship between females changed. If there were several individuals in the group in the state of estrus at the same time, the dominant females hindered the reproductive success of the lower-ranking sheep.ConclusionsThe present study shows that the patterns of reproductive behavior in males of different species of sheep are similar. However, it was revealed that the species differ in the length of those patterns. A high variability in the strategies of sheep reproduction was observed. For future research, it would be beneficial to focus on the features of the reproductive behavior of female sheep depending on the genotype.

The article deals with results of theoretical and experimental studies of a radio-measuring frequency transducer of optical radiation based on MOS transistor structures with negative differential resistance and an active inductive element. Analytical expressions of the transfer function and sensitivity equations are obtained on the basis of the solution of a system of non-linear equations. Experimental studies of the current-voltage dependences of the proposed transistor structure of the frequency converter of optical radiation in static and dynamic modes confirm the presence of a section with negative differential resistance on the I-V characteristic, which compensates for the losses in the oscillatory circuit. The theoretical and experimental dependences of the frequency of generation on the power of optical radiation are presented. The dependence of sensitivity of the developed transducer on the power of optical radiation varies from 9.7 kHz/μW/cm 2 to 24.5 kHz/μW/cm 2 . A mathematical model of the thermal conditions of a radio-measuring frequency transducer of optical radiation has been developed. The calculation of non-stationary thermal conditions of the frequency transducer allowed to obtain the temperature field of the transducer integrated circuit. The time to achieve the steady state does not exceed 5.8•10 -4 s. Moreover, the maximum temperature of overheating for the elements of the integrated circuit of the transducer does not exceed 2.49 C.
