Unlike adults, subadult birds often exhibit distinct migratory patterns and continually refine their migratory behaviour and destinations as they mature. Consequently, the influence of subadult movements on overall migratory connectivity might be different from that of adults. However, current studies on migratory connectivity often overlook population age structures, predominantly focusing on adults. In this study, we investigated the role of subadult movements in shaping population level connectivity by using satellite tracking data from 214 black-necked cranes, <em>Grus nigricollis</em>, in western China. We first assessed the variances in spatial separation in different age cohorts using the continuous temporal Mantel correlation coefficient with data from 17 juveniles tracked in the same year for 3 consecutive years. We then calculated the continuous temporal migratory connectivity for the entire population (comprising various age groups) from 15 September to 15 November and compared the result to that of the family group (consisting of juveniles and adults only). Our results revealed a positive correlation between temporal variation in spatial separation and age after the juveniles separated from the adults, suggesting that subadults may have fine-tuned their migration paths. Moreover, the migratory connectivity of the all-age cohort was moderate (below 0.6) in the winter season, and notably lower than that of the family group during the autumn period. Given the considerable impact of subadults on migratory connectivity, we recommend using data collected from birds across all age categories to improve the precision of population level migratory connectivity estimates.</p></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"215 ","pages":"Pages 143-152"},"PeriodicalIF":2.3,"publicationDate":"2024-08-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141950244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite this, few studies have directly measured links between among-individual behavioural and trophic variation. Invasive species like the round goby, <em>Neogobius melanostomus</em>, are often found to have consistent among-individual differences in behaviour within and between populations across their invasion front. Therefore, an individualized approach to invasive populations and their ecological interactions may be valuable to understanding their impacts on recipient ecosystems. Using nonlethal methods to measure trophic variation (i.e. stable isotope analysis via fin clips) and passive individual tagging, we analysed behavioural trait/personality variation and trophic variation to explore links between the two. Focusing on an established population of round gobies in the Guldborgsund strait in the southwest Baltic Sea, we found significant among-individual variation in bold–exploratory traits in novel environment and refuge emergence assays. We also found strong intraspecific trophic variation, with particularly high variation in carbon-12 – carbon-13 (δ¹³C), suggesting that individual round gobies differ in what they are feeding on and/or where they forage. Diet reconstruction results support previous studies showing that gastropods and bivalves are major contributors to their diet, but the large differences in isotope values suggest that individual variation influences how they interact with prey communities. There were few links between behavioural and trophic variation; nevertheless, this study shows that measuring behavioural–trophic links is a viable approach for exploring whether and how behavioural traits may influence individual level ecological variation.</p></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"215 ","pages":"Pages 263-280"},"PeriodicalIF":2.3,"publicationDate":"2024-07-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0003347224001921/pdfft?md5=027d7b19c489b08f6e8d8a0a7abb3fb6&pid=1-s2.0-S0003347224001921-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141997719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Understanding changes in animal behaviour in response to tourism activities can inform the trade-offs between negative impacts and socioeconomic benefits. There are public claims that cage-diving activities may condition white sharks, <em>Carcharodon carcharias</em>, to interact with boats, and may potentially increasing risk of shark bites. We tracked the fine-scale movements of 73 white sharks in relation to cage-diving boats using acoustic telemetry between 2018 and 2022 at Neptune Islands, Australia, to investigate associative behaviour and factors potentially influencing residency and time spent in proximity to the cage-diving boats. White sharks spent gradually less time near cage-diving boats throughout their residency at the tourism site. This behaviour was consistent across individuals, years, sexes and sizes. Sharks, however, resumed their natural behaviours (i.e. initial amount of time near the cage-diving boats) each time they returned to Neptune Islands, suggesting that the observed habituation (i.e. loss of response to the stimulus used to attract sharks) did not last for long periods. These trends support the lack of long-term learnt behaviour of white sharks increasingly interacting with boats. Our results indicate that current management strategies such as regulating the number of days the industry can operate at the site and the amount of food-based attractant used, and reducing the amount of bait consumed can limit associative behaviour between white sharks and boats, while enabling continued opportunities for white shark tourism. Understanding how wildlife associate with humans can help ensure that best practices are in place for both the targeted animals and the people involved, particularly in the case of threatened and potentially dangerous species.</p></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"215 ","pages":"Pages 227-239"},"PeriodicalIF":2.3,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0003347224001593/pdfft?md5=80527300217018183957e417cbc7a9c4&pid=1-s2.0-S0003347224001593-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141796427","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hybrid loaches generally showed strong avoidance of the open field, whereas epigean loaches avoided the open field more in light than in dark conditions. Other tests were performed in darkness only. Cave loaches showed more consistent lateralization in turning behaviour during exploration of the Y-maze than the other two groups, indicating a search strategy optimized for nonvisual navigation. In all groups, complex maze learning was evident in the first half of the 15 trials, with a reduction in latency of departure from the starting chamber, and in both time and track length to reach the food chamber. However, cave loaches were far more successful in finding food than were epigean loaches and hybrid loaches. When the path to the food chamber was altered, epigean loaches generally responded by changing their route, whereas cave loaches tended to continue following a previously learned path and hybrid loaches exhibited intermediate behaviours. In conclusion, the enhanced ability of cave loaches to navigating labyrinths in the dark compared to their epigean ancestor suggests the evolution of behavioural traits that optimize survival in caves.</p></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"215 ","pages":"Pages 111-124"},"PeriodicalIF":2.3,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S0003347224001891/pdfft?md5=8d21e52bfa3bb6909f0507874ff92074&pid=1-s2.0-S0003347224001891-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141961982","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The individuals that changed their movement the most tended to be higher-ranking, socially connected baboons, which are the focus of the city's baboon management programme, seeking to keep baboons out of urban areas.

The effectiveness of the antipredator defences can depend on various ecological contexts such as predator density and the development stages of the prey species. Males and females often exhibit remarkably different morphologies, behaviours and life histories, and the sexual differences are expected to generate different ecological contexts for males and females, potentially driving the evolution of sex-specific antipredator defences. In the horned beetle <em>Gnatocerus cornutus</em>, males have enlarged mandibles, but females lack this exaggeration. As potential defences against predators, these beetles either become immobile or run away. In this study, we established populations subjected to sex-specific predation. We found that male locomotion was increased in populations subjected to male-specific predation and that female immobility was increased in populations subjected to female-specific predation. We also found that males appeared on the surface of food resources more frequently than females. Given such differences in microhabitat preferences, the males are more likely to be detected by predators than the females. The sexual differences in morphology and microhabitat preferences may generate different predatory environments for males and females, resulting in males using locomotion to escape from predators and females using immobility to hide from them. In this laboratory selection experiment, we did not observe the evolution of the opposite sex's antipredator traits in response to sex-specific predation. We detected no intersexual genetic correlation of immobility and locomotion.
