The observation was carried out for 13 months from January 2019 to February 2020 (except February 2019) in Indonesia's Bengkalis waters. This study's purpose was determined to determine the spawning season, fecundity, and behavior of this species. The results showed that the relationship between length and weight positively correlates with the length-weight of male&nbsp;<em>T. macrura</em>&nbsp;(R² = 0.84) and female (<em>R</em>² = 0.67), while the length-weight of all males and females were reported to be (<em>R</em>² = 0.95). Meanwhile, the relationship between fecundity and length-weight has no relationship. Furthermore, the spawning season lasted all through the year, and it occurred at every low tide (dark moon) and high tide (full moon). Despite being discovered occasionally in a limited amount, the greatest amount of&nbsp;<em>T. macrura</em>&nbsp;was reported between July and September each year.</p> 2021-10-12T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Toxic impacts of a mixture of three pesticides on the reproduction and oxidative stress in male rats 2021-08-18T21:22:34+00:00 Narimene Bouabdallah Leila Mallem Cherif Abdennour Amel Chouabia Mohamed Tektak <p>The present study investigated the toxic effect of a mixture of three pesticides (cypermethrin, mancozeb, and metalaxyl) on reproduction and oxidative stress parameters in male <em>Wistar</em> rats. Animals were treated at doses 1/60, 1/30, and 1/10 LD50 of each pesticide daily in the diet for 08 weeks. At the end of the treatment period, animals were sacrificed by decapitation. The results indicate a decrease in the absolute weight of testes and epididymis, the serum of testosterone hormone, and cholesterol levels. These parameters were significant reduced in males exposed to the mixed pesticides. A reduction in sperm concentration, motility, and viability also was observed. Besides, the ingestion of mixed pesticides at all three concentrations caused a significant decrease in GSH, GPx levels and an increase in MDA levels compared to the control group. This was accompanied by histopathological changes in testis and epididymis of rats such as seminiferous tubules degeneration, decreasing number of spermatogenic cells, edema, expansion of interstitial spaces, cell necrosis, and reducing the diameter of the epididymal tube compared to the control group. Thus, we strongly suggest that the mixture of pesticides causes damages to the male reproductive system.</p> 2021-10-14T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Climate impacts on reproductive performance of Romanov sheep in the moderate climate 2021-08-18T21:21:16+00:00 Dražen Đuričić Attila Dobos Jozo Grbavac Charlotte Stiles Iva Bacan Željko Vidas Franjo Marković Predrag Kočila Marko Samardžija <p>This study aimed to investigate the climatological impacts of air temperature, sunshine duration, and rain precipitation, in a moderate climate, on the reproductive performance of Romanov sheep in the continental part of Croatia, during two consecutive years (2019-2020). Our study included 549 matings with 520 successful conceptions at 5 Romanov sheep farms, and the fertility rate was 94.72%. The percentage of lambs delivered in winter was 53.27% (n = 277), in spring 20.19% (n = 105), in summer 14.23% (n = 74) and 12.31% in autumn (n = 64). According to percentile ranks and classification ratings, thermal conditions have been described as very warm (during 2019-2020), while precipitation conditions, expressed in percentiles, were wet (during 2019) but dry (during 2020) for this region. The peak of sexual activity was from mid-August until October in 2019 and from the end of August to November in 2020 for Romanov sheep in northwestern (NW) Croatia. A Kruskal-Wallis test showed a statistically significant difference in the number of pregnant ewes during the different mating seasons in the year (<em>p</em> &lt; 0.001). Therefore, we can assume that air temperature, precipitation volume, and sunshine duration during the different seasons could impact the reproductive performance of Romanov sheep in a moderate climate.</p> 2021-09-27T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology Modulation of sexual behavior of Morada Nova ewe by the season of the year in a semiarid equatorial environment 2021-08-18T21:18:17+00:00 Edilson Paes Saraiva Luana de Fátima Damasceno dos Santos Dermeval Araújo Furtado Edgard Cavalcanti Pimenta Filho Tarsys Noan Silva Veríssimo Natanael Pereira de Arruda Leonardo Santos Silva Severino Guilherme Caetano Gonçalves dos Santos Geni Caetano Xavier Neta Larissa Kellen da Cunha Morais José Danrley Cavalcante dos Santos <p>The objective was to evaluate the effect of the season on the sexual behavior patterns adopted by Morada Nova sheep in the Brazilian semiarid region. A total of 55 and 59 female sheep were used in the rainy and dry seasons, respectively, attended by four males of the same breed in rotation. The females identified in oestrus were released in a pasture, together with the breeder of the day for each season, and aspects of sexual behavior were measured for an uninterrupted period of 11 hours/day. Assuming a negative binomial distribution, the behavioral frequencies were subjected to deviation analysis and compared using the chi-square. Heading in the male was observed more frequently during the rainy season (0.12) and shifts with higher temperatures; the turn of the head in relation to the man was observed more frequently during the dry season (2.49). The interactions between seasons and shifts significantly affected the following behaviors: sniffing the male, sniffing the male's urogenital region, wagging the tail, lifting the tail, and urinating. Behavioral variables were influenced by the season. Morada Nova sheep reduce their water intake and grazing time to engage more efficiently in reproductive activities, thus demonstrating an ability to adapt to the Caatinga.</p> 2021-09-28T00:00:00+00:00 Copyright (c) 2021 Journal of Animal Behaviour and Biometeorology
