Animals typically have more aggression signals than submission signals. However, some social species do show multiple submission signals, and the context in which these different signals are used is often not well understood. In the current study, we assessed agonistic interactions within groups of the cooperatively breeding daffodil cichlid fish (Neolamprologus pulcher) to investigate the relationship between the aggressive behaviours of the dominant breeding pair, and the submissive responses of the highest ranked subordinate within the group. Daffodil cichlids may respond to aggression by fleeing or by the production of either a tail quiver display or a head up display. Among the two submission signals, the tail quiver display was used more frequently in response to a threat display, while head up displays were produced approximately equally in response to both threat displays and overt aggression. An exaggerated version of the head up display was given more often in response to overt aggression, suggesting a graded submissive response both within and between the two submission signals. Within fish, the frequency of head up displays, but not tail quiver displays, correlated positively with the frequency of threat displays received. The current study helps us to better understand the use of submission signals in a highly social vertebrate and sheds light on submission as an understudied aspect of communication.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46153392","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 ruminants’ more efficient digestive system, requiring lower volumes of forage, is predicted to provide an advantage over hindgut fermenters with respect to foraging effort, but this may be offset by their need for higher quality forage. We contrasted the activity of two similarly-sized, syntopic grazers, black wildebeest (Connochaetes gnou), a ruminant, and Cape mountain zebra (Equus zebra zebra), a hindgut fermenter, using camera trap data and tested the volume-requirement and the nutrient-driven hypotheses, seasonally. Zebra and wildebeest activity varied seasonally, potentially due to differences in resource availability. In winter, a greater proportion of wildebeest were recorded grazing relative to zebra, supporting the nutrient-driven hypothesis, whilst the inverse occurred (although not significantly) in summer, supporting the volume-requirement hypothesis. Seasonal variation in resources may provide temporal foraging trade-offs of benefits for ruminants and hindgut fermenters.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-10-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45009723","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}

However, variation in the response to different neighbours is less known. In this work, I examined the territorial behaviour of male scops owls during countersinging interactions with two familiar neighbours and I asked whether vocal behaviour of the focal male reflected dear-enemy relationships. Analysis revealed that the focal male’s vocal frequency was associated with (1) the degree of instability of the territory boundary shared with a neighbour and (2) the motivation to persist in the dyadic interaction with that neighbour. Patterns of movement directed to specific individuals suggest that scops owls do discriminate between neighbours. A case of partial territory takeover was observed that was accompanied by temporal changes in vocal frequency in one of the opponents, confirming that vocal frequency is a flexible, context-dependent feature of the relationship of neighbouring scops owls.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47609822","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 describe the emergence and directional spread of a novel song variant within a population of White-throated Sparrows in central British Columbia, Canada. Birds in this population have been singing a doublet-ending song since the early 2000s. In 2015, we detected a novel variant, consisting of a doublet-ending song with a distinctive amplitude modulation in the first note (Modulated-Doublet). We banded and recorded birds from 2015 to 2020 and classified songs using both audio and spectrographic analysis. The proportion of birds singing the Modulated-Doublet increased, replacing the Unmodulated-Doublet over time. Additionally, the modulation became more pronounced, both across the population and within individual birds, over successive years. The rapid spread suggests there may be several transmission biases driving the adoption of this novel song over the older established variant.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46061221","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}

Here, we exposed Hart’s rivulus (Anablepsoides hartii) to conspecific or heterospecific alarm cues from donors that were either smaller or larger than the mean focal rivulus size. Smaller rivulus reduced foraging in response to conspecific and heterospecific cues, regardless of donor size. However, larger rivulus exhibited no reduction in foraging towards small conspecific cues and increased foraging towards small heterospecific cues. Additionally, while conspecific donors elicited strong predator avoidance, rivulus exhibited stronger responses to large vs. small heterospecific cues. Our results demonstrate that the value of alarm cues is shaped by the interacting effects of receiver size and the size and species of cue donors.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47563365","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 found that both rules were supported for native Pannonian red deer from Central Europe.

It is more likely that an individual cooperates with closely related kin (e.g., in food sharing), and particularly with close maternal kin. In female philopatric species, such as Cebus spp., mother–offspring bonds likely explain patterns of maternal kin biases. On the other hand, the explanation of the evolution of food-sharing among non-kin is diverse. Capuchin monkeys (genera Cebus and Sapajus) are interesting to study cooperation since this is a critical behaviour to gain and protect ecological and reproductive resources in the wild, including care of their offspring. We performed an experimental protocol to induce behavioural observations with a provisioning technique using chicken eggs in a wild group of white-faced capuchin monkeys (Cebus versicolor). We aimed to test whether this white-faced capuchin monkeys engaged in food-sharing in the wild, describing the pattern of this cooperative behaviour. Furthermore, we also described some conditions that might affect this behaviour. We observed that these capuchins shared the eggs in passive exchanges, meaning that possessors let other individuals to eat from their egg. Our results further suggest that these exchanges may be due to mainly maternal kin biases. This study offers a preliminary observation of a little-studied capuchin species in the wild and adds information about how cooperation works in the wild.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-09-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45659534","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}

Pairs fared better than single females in defending a brood, and age had a strong effect on contest outcomes even though defenders and intruders were of the same age. Pairs also produced larger broods than single females, but only on larger carcasses. The results and a review of prior studies suggest that the benefits for a male that stays with a partner during the post-hatch period, whether gains from offspring success or protecting mating opportunities, are observed primarily in the context of intruder pressure, and that paternal care such as regurgitations to young and nest maintenance would not have evolved in a rival-free world.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2022-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47441769","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}
