Although a wide variety of noises from different sources is common in cities, the impact of non-engine noise on animal calls is less studied. In a natural experiment, we evaluated the effect of different urban noises on the advertisement calls of urban frogs (<i>Eleutherodactylus nitidus</i>) in the metropolitan area of Puebla, Mexico. We recorded and analyzed 672 advertisement calls from 28 male frogs and the corresponding environmental noises from three distinct localities. Our analysis focused on four acoustic properties of the calls: inter-call interval, call duration, dominant frequency, and call amplitude. To standardize the amplitude measurements of sound pressure levels produced by noise and frog calls, we employed a practical approach using a reference signal for calibration. We treated the longitudinal data of different noises occurring before, during, and after advertisement calls as repeated measures within the urban locations. During our samplings, frogs called amidst spontaneous urban noises, including dog barking, fireworks, and vehicle engine sounds. Our results indicate that vehicle engine sounds and dog barking do not cause significant distortions in the calls of these urban frogs. However, we observed slight variations in the dominant frequency of calls, decreasing by 11 Hz, during and after fireworks. Given the observed plasticity of <i>E. nitidus</i> in response to noise, urban noises may not pose a severe problem for this urban frog.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"27 3","pages":"177 - 187"},"PeriodicalIF":1.1,"publicationDate":"2024-09-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-024-00449-5.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249210","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We predicted that solitary bulls would reduce their nocturnal use of territorial stands and join herds to reduce predation risk from nocturnally hunting lions (<i>Panthera leo</i>), but that these responses would differ across rutting and non-rutting seasons. We used camera trap data and modelled solitary bull and herd activity over 24-hour daily cycles, across rutting and non-rutting seasons. We calculated the proportion of images with solitary bulls and herds across nocturnal and diurnal periods, across both seasons. We show that solitary bulls are predominantly diurnal across both seasons, but the probability of nocturnal detection is higher in the rutting than in the non-rutting season. Furthermore, we recorded a lower proportion of solitary bulls to herds at night in the non-rutting relative to the rutting season. Thus, wildebeest bulls may trade-off predation risk for mate acquisition during the rutting season but reduce risky solitary behaviour during the non-rutting season.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"27 3","pages":"189 - 197"},"PeriodicalIF":1.1,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-024-00448-6.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142175839","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Previous studies have found prevalent heterospecific mating between <i>C. sexmaculata</i> male and <i>P. dissecta</i> female, documenting the effects of heterospecific male <i>C. sexmaculata</i> on the reproductive output of <i>P. dissecta</i> female. In light of these observations, we conducted an experiment examining the influence of heterospecific male age on the reproductive output of <i>P. dissecta</i>. This study involved three age groups of male: (a) young (10–20 days), (b) middle (30–40 days), and (c) old (50–60 days). These males were introduced into Petri dishes with conspecific mates of <i>P. dissecta</i>. Across all experimental treatments, we examined the impact of three different age cohorts of <i>C. sexmaculata</i> males on the mating and reproductive attributes of <i>P. dissecta</i>. Our findings unveiled that older heterospecific males, which displayed reduced choosiness and heightened activity, engaged in reproductive interference to a greater degree than younger <i>C. sexmaculata</i> males during conspecific <i>P. dissecta</i> mating. Further, post-mating encounters with young heterospecific males led to a reduction in the reproductive output of female <i>P. dissecta</i>.

The results of this study suggest that the aggressiveness between morphotypes is of orange and red over yellow. The orange morph was related to winning the greatest number of encounters, whereas yellow lost the most. The red morpho registered the greatest number of ties. Interestingly, in contests between more aggressive morphs (orange and red), fish tended to modulate and lower aggressiveness levels, possibly to avoid injuries. In contrast, the least aggressive morphotype (yellow) tended to raise its aggressiveness against the most successful morphotype and lower it in matches against its own color, changing to a scheme between contenders with symmetrical aggression levels.

Despite being a conspicuous species, little is known about its copulatory behaviour. In this research, we studied the copulation behaviour of Southern Lapwings and identified specific behaviours that preceded copulation events. Focal observations were made during one year on two pairs of lapwings that inhabit an urban area in the southeastern Pampas region, Argentina. A total of 110 intra-pair copulations were recorded (pair 1 = 64 and pair 2 = 46). Frequent copulations began 97 and 64 days before the first egg-laying, respectively, although the highest frequency occurred before the onset of the first nesting attempt. The Southern Lapwing copulated during all daylight hours, with a peak in the morning. Copulation occurred for up to five consecutive days, and the maximum number of copulations observed in a single day was four. Courtship and territory defence were the most common behaviours preceding copulation. Among the multiple hypotheses that have been proposed to explain frequent intra-pair copulation, our results seem to support two of them: the territory signalling hypothesis and the social bond hypothesis. The high population density coupled with the low availability of territories and a strong social bond based on cooperation and coordination could support both hypotheses, respectively. Given that the social environment can modify the behaviour of plovers, future research should evaluate the copulation behaviour at different population densities and the adaptive functional significance of this behaviour.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"27 3","pages":"205 - 212"},"PeriodicalIF":1.1,"publicationDate":"2024-06-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141347231","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
