Understanding how social strategies are shaped by various potentially interacting factors is fundamental to understanding social evolution. We used highly gregarious catfish from the subfamily Corydoradinae to assess how familiarity, environmental cues, and relative body size impact coordination and communication within pairs of fish. Unlike many other model systems, Corydoradinae catfish exhibit clear inter-individual social overtures (termed ‘nudges’) that serve as an easily quantifiable measure of social motivation. Our results show that relative size was a significant predictor of individual nudges across all factor combinations, with smaller individuals nudging at higher rates than their larger partner. However, this effect was most pronounced among socially unfamiliar individuals that shared an environmental background (i.e. diet), but was largely absent when fish were familiar with one another or came from different environmental backgrounds. Cories thus appear to differ from the common behavioral model system three-spined sticklebacks in that familiarity and shared environmental background do not have the same effect on social preferences. Together these results demonstrate that relative body size is important in social interactions of these fish, but that other factors alter its impact. We thus show that individual characteristics affect social motivation in complex ways that likely influence group coordination and composition. This may explain the persistence of the highly heterogeneous groups these fish form in the wild.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"229 ","pages":"Article 105218"},"PeriodicalIF":1.3,"publicationDate":"2025-05-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144138124","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}

While extensively used to study drug effects, the CPP paradigm has been less frequently applied to investigate the effects of natural stimuli. Furthermore, most studies using this paradigm have been conducted with rodents. This study utilizes the CPP paradigm to investigate the rewarding properties of nursing in lactating rabbits, a unique mammalian behavior that occurs once daily. We found that nursing induced CPP in the lactating doe, which we interpret as a positive affective state—an event fulfilling a motivational drive that occurs only every 24 hours.

Underlying social dynamics may influence such instances of grouping behavior. Despite social behavior being an expanding niche in shark science, little is known about the social behavioral patterns of the tiger shark worldwide. Between 2023 and 2024 in Fuvahmulah Island, Maldives, 36 pair-wise non-random social interactions were observed at the provisioning site via video recordings by 40 photo-identified mature female tiger sharks. Social behaviors previously identified in white sharks and tiger sharks across multiple locations, such as <em>give way</em>, <em>swim by</em>, <em>parallel swimming</em>, <em>follow give way</em>, and <em>stand back</em>, have also been documented in tiger sharks from Fuvahmulah Island. Furthermore, this study presents two newly observed antagonistic social behaviors — <em>submission</em> and <em>push away</em> — described here for the first time. Within the mature female tiger shark aggregation in Fuvahmulah, a size-based hierarchy was observed, with certain individuals displaying the majority of dominance and social interactions. The asymmetry in the monthly display of social behaviors suggests an intra-specific variability of tiger shark movements to different home ranges. These findings deepen our knowledge of the tiger shark social behavior, highlighting data gaps in Maldives and ensuring effective conservation measures for this species.

The direction of visual lateralisation (left or right) against prey, predator, and conspecifics was positively associated with aggressiveness, exploration-avoidance, and shyness-boldness.
