We repeatedly quantified the courtship display elements used by 16 males over multiple days and specifically tested whether male presence and displays at courts could be explained by variation in environmental conditions (forest shade with small sunny gaps, large sunny gaps, and cloudy), male age (juvenile or adult), or yet the social context (other males and female visits) during displays. Our results show that total male presence and time displaying varied with the total number of other males and female visits at the court. In addition, the type of courtship elements used in displays (assessed by principal component analysis) also varied with the presence of both females and other males on the court. Male age, however, did not influence male activity. Overall, the social context at the court was the strongest predictor of within-population variations in male courtship display, whereas light conditions only affected display duration. Variation in display repertoire with female presence might reflect variation in female preferences. In addition, similar displays among males of different age classes suggest a competitive, rather than cooperative lek system of White-throated Manakins in Central Amazonia.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"165 - 176"},"PeriodicalIF":1.1,"publicationDate":"2021-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00371-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41381961","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}

Gibbons are frugivorous small apes. In this study, we investigated how gibbons varied their social and calling behaviors in response to changes in fruit availability. Activity budget, travel distance, sleeping time, and song duration of two wild Northern Gray gibbon (<i>Hylobates funereus</i>) groups were investigated during both mast and non-mast fruiting periods at the Danum Valley Conservation Area, Sabah, Malaysia. Gibbons traveled longer, entered the sleeping tree later, and spent more time engaged in singing, playing, and grooming behaviors during the mast fruiting period. Playing and grooming are intra-group social interactions. Gibbon songs were sung antiphonally within and among groups, indicating that singing is both an intra- and inter-group social interaction. Furthermore, copulatory behaviors that occurred during female pregnancy were observed during the mast fruiting period, suggesting this might be a social interaction behavior rather than a reproductive activity. Our results show that gibbons extended their daily activity schedules during the mast fruiting period and spent this extra time on social interactions. We examined whether male song complexity increased during the mast fruiting period by using the Levenshtein distance method, but we did not find such a trend. In the mast fruiting period, gibbons may consume more energy than in the non-mast fruiting period. Social and calling behaviors are energetically costly. Our results show that there is a link between energy intake and social and calling behaviors.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 3","pages":"153 - 163"},"PeriodicalIF":1.1,"publicationDate":"2021-05-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00370-1","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43096406","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}

In the guppy fish (<i>Poecilia reticulata</i>), a key element in the mating behavior and reproductive success of males is female mate choice, which is predominantly based on visual signals. Females choose attractive males based on body coloration, and males court females by displaying their coloration. Here, we demonstrate that guppy males exhibit morphological and behavioral adjustments in response to changes in the visual environment. Males reared in turbid water had more conspicuous coloration than males reared in clear water, with higher intensity of carotenoid-based and ultraviolet colors, but not a larger area of red spots on the body. However, they performed less courtship displays in turbid water than males reared in clear water performed in clear water. Thus, increased coloration in turbid-water males was not accompanied by increased effort to display it. Although our findings demonstrated developmental plasticity in mating-related traits, turbidity-induced alteration in coloration did not match behavior change as could be predicted by favoring male attractiveness.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 2","pages":"127 - 136"},"PeriodicalIF":1.1,"publicationDate":"2021-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00369-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49353150","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}

We evaluated the individual response to playbacks of the wing trill stimulus and compared it to the response to other two control stimuli (vocalizations of the scaled dove and the southern house wren). We found that doves’ probability to become vigilant or to display freezing behaviour was higher after a wing trills stimulus in comparison to the other playback stimuli.

However, there are costs associated with living in a group such as competition for food and/or mates with other members of the group, higher chances of disease transmission, etc. Group size dynamics can change with the biotic and abiotic environment around individuals. In the current study, we explored the links between group size dynamics and intestinal parasites of Indian peafowl (<i>Pavo cristatus</i>) in the context of seasons and food provisioning. Data for group size was collected across three seasons (pre-monsoon, monsoon and post-monsoon) at three field sites (Morachi Chincholi, Nashik and Rajasthan). Individual and group sightings of peafowl were noted down along with group size and composition (no. of males, females, adults, juveniles and sub-adults). Faecal samples were collected from food provision and non-provision areas across the same three seasons at same field sites. Parasite load in the samples was quantified using microscopic examination. Group size was significantly higher in pre-monsoon season as compared with monsoon and post-monsoon seasons. Monsoon and post-monsoon seasons had higher intestinal parasite prevalence and load as compared with pre-monsoon season. Thus, group size and intestinal parasites of Indian peafowl have an inverse relationship across seasons. Parasite load was significantly greater at food provision sites as compared with non-provision sites while parasite prevalence was comparable. Aggregation of individuals at the food provision sites may influence the parasite transmission and group-size dynamics in Indian peafowl. In conclusion, Indian peafowl are behaviourally plastic and fission-fusion of social groups may allow them to tackle ecological pressures such as predation and parasite transmission in different seasons.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 2","pages":"107 - 117"},"PeriodicalIF":1.1,"publicationDate":"2021-03-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00366-x","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41891015","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}

The study was conducted from 2014 to 2019 in the Ría de Arousa (Northwest Spain). This study highlights that both species use this area as a foraging ground, although they show different patterns of occurrence (bottlenose dolphins were always observed in the ria and common dolphins were mostly observed outside). During the study period, bottlenose dolphins and common dolphins were only observed on five occasions at the same time and in the same area, including three occasions which led to the displacement of the common dolphin(s), and one lethal interaction. In this event, several bottlenose dolphins, including adults and calves, and males and females, aggressively herded, chased, and assaulted a common dolphin. After approximatively 10 min, the common dolphin corpse appeared floating at the surface, and several adult male bottlenose dolphins repeatedly pushed the body underneath the water surface and an (attempted) copulation was witnessed. We suggest that the common dolphin could have been killed for competition for food resources or practice for infanticide, and sexual arousal might have been triggered by expression of dominance. Further information about the occurrence of such behaviors, and the outcomes through specific studies on fitness would be crucial to further understand the implication of such events.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"24 2","pages":"95 - 106"},"PeriodicalIF":1.1,"publicationDate":"2021-03-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/s10211-021-00363-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47513633","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}
