Nevertheless, chemical communication in anurans (i.e. frogs and toads) has received less attention, as individual decision making in male–male competition and female choice is predominantly influenced by acoustic signals. In recent years, there has been increasing evidence indicating that chemical cues can affect male–male competition behaviours in anuran species, including aggression and call activity. However, few studies have investigated whether chemical cues affect the spectral traits of acoustic signals, which are important for attracting potential mates. In the present study, we investigated variation in the dominant frequency of advertisement calls in Hainan frilled treefrogs, <em>Kurixalus hainanus</em>, comparing the calls of males vocalizing alone to those in the presence of conspecific odours. Our results showed that males with a higher dominant frequency significantly decreased their frequency when exposed to conspecific odours, while those with a lower frequency increased it. Further analysis revealed that the dominant frequency of advertisement calls during the stimulus period was closer to the average level than that during the spontaneous period, a trend observed only in the disturbance odour group. This adjustment may serve to maintain attractiveness to females in the face of potential predation risk. Overall, our study provides evidence that conspecific chemical cues affect the spectral traits of frog vocalizations and has an implication for understanding how males balance survival and reproduction by adjusting their calling strategies.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123032"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738092","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}

For marine predators that spend extended periods at sea and underwater, the use of animal-borne video provides a novel method of observing individuals in their environment and the foraging behaviours they employ. The endemic Australian sea lion, <em>Neophoca cinerea,</em> is listed as endangered, with its populations declining by more than 60% over the last 40 years. Due to the highly subdivided genetic structure of Australian sea lion populations, an intimate understanding of their foraging behaviour, throughout their distribution, is needed to support targeted management at the breeding site level. Here, we use animal-borne video collected from 10 adult female Australian sea lions from five colonies in South Australia to identify the prey capture tactics they use across different benthic habitats. We identified a variety of prey capture tactics (probing, chasing, pelagic ambushing of schooling fish, flipping rocks/substrate and sit-and-wait predation), exploiting a range of benthic habitats, including seagrass meadows, bare sand plains and macroalgae reefs, while hunting diverse prey, such as benthic/epibenthic fishes, cephalopods and elasmobranchs. The prey capture tactics most frequently observed were probing and chasing, which were used by all individuals, whereas flipping rocks, sit-and-wait predation and pelagic ambush were less frequent. Using specialist prey capture tactics, such as sit-and-wait predation, may increase the capacity of sea lions to exploit a greater diversity of prey and benthic habitats, which could increase their overall success and fitness. This study underscores the significance of animal-borne video as a crucial tool for identifying and mapping the critical habitats and resources essential for Australian sea lions.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123108"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738098","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}

Birdsong is a signal used in agonistic interactions between territorial rivals, and birds may modify their song and singing behaviour in response to noise. However, if these modifications are still ineffective, this can lead to increased conflict between rivals. Here, we asked whether experimental traffic noise induces immediate changes in acoustic characteristics of song and aggressive behaviour in populations and territories that differ greatly in traffic noise exposure. We conducted simulated territorial intrusions on Galápagos yellow warblers, <em>Setophaga petechia aureola</em>, living on Santa Cruz (high traffic) and Floreana (low traffic) islands. Territories were either adjacent to the nearest road or at least 100 m away from it. We assessed the focal birds’ physical response levels and recorded their vocalizations in response to the playback of conspecific song (control) and conspecific song coupled with traffic noise (noise treatment). We found that, on both islands, birds living in territories adjacent to roads increased their aggression levels with experimental noise compared to control, while birds living farther away from roads decreased their aggression levels. Birds on both islands increased minimum frequency of their songs during the noise treatment, irrespective of their distance to a road. However, changes in peak frequency and duration of their songs depended on the habitat they live in. Our results suggest behavioural flexibility in territorial responses and birdsong in response to traffic noise, which appears to depend at least in part on prior experience with traffic noise.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123119"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143737903","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}

Despite the prevalence of group living, it remains challenging to study the proximate factors that promote variation in this behaviour. Meadow voles, <em>Microtus pennsylvanicus</em>, vary in social organization in response to seasonal cues in the wild, providing a remarkable opportunity to study mechanisms that support changing grouping behaviour within a single species. In summer, female meadow voles are territorial and maintain exclusive home ranges, while in winter, they live in mixed-sex groups. Laboratory manipulations of photoperiod reproduce seasonal variation in social behaviour in this species, demonstrated by altered short-term dyadic interactions during behavioural tests. To assess changes in group social dynamics, we implemented an automated tracking system using radiofrequency identification technology to monitor free-moving voles housed in long daylengths and short daylengths in multichambered habitats over extended intervals. We developed open-source software to model each animal's position within the habitat and to describe co-occupancy patterns. Photoperiod drove robust and pronounced changes in group social behaviour, recapitulating natural seasonal transitions in the wild. Voles housed in short, winter-like days spent more time in groups, formed larger, more evenly mixed groups and shared a single home-chamber more often than long-day voles. Short-day voles were more active than long-day voles but rested in groups, thus cohabitation was strongly correlated with ultradian rhythms in activity. These metrics of group dynamics will allow more nuanced assessment of the effects of manipulations on social behaviour in voles and other species, as both habitat and software are adaptable for use with other rodents.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123084"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738270","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}

While most predators have distinctive diel activity periods (e.g. only hunt at night), others are more variable. Animals that never stop moving may still show diel activity patterns, but how their search mechanisms change throughout the cycle is less clear. We used biologgers to quantify volume-restricted search (VRS or three-dimensional ARS) by great hammerhead sharks, <em>Sphyrna mokarran</em>, and record potential prey encounter rates. Analysis of 736 dives suggested that VRS dives tended to be shorter, with faster swim speeds, than non-VRS dives.

Task complexity is assumed to have an influence on behavioural lateralization, that is the strength of lateralization increases with increasing task complexity. However, systematic comparisons of different lateralized tasks in nonprimate species are rare. Therefore, this study aimed to investigate the influence of task complexity on paw preference in a rodent species, the laboratory rat, <em>Rattus norvegicus</em> f. <em>domestica</em>. Male and female rats were tested in five different paw preference tests, including complex tasks, such as food reaching, tool use or string pulling, and simple routine behaviours, such as climbing and standing. For all tests, the distribution of paw preferences was assessed, and the differences in strength and direction of lateralization were tested among the tests. The temporal consistency of paw preference was also investigated, and it was examined whether the paw used first indicates an individual's overall preference. Results showed that a large number of rats were strongly lateralized for two complex tasks (food reaching and tool use), whereas the vast majority was ambilateral for string pulling, climbing and standing. Furthermore, only food reaching and tool use were temporally consistent in the direction and strength of lateralization. Overall, strength decreased over time. Sex showed no effect, but individuals that used the left paw first were more strongly lateralized. In conclusion, task complexity can affect behavioural lateralization in rats; however, other attributes, such as task novelty, should also be considered. Moreover, artificial test situations, which favour the use of a single paw, likely reveal paw preferences, whereas routine behaviours or alternating paw use are associated with ambilaterality. These findings complement existing studies that focused on food reaching tests and underline the need for investigating behavioural lateralization in different contexts and test situations.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123118"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738198","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}

While much attention has been paid to the responses of seabirds to dimethyl sulphide (DMS) or of insectivorous birds to herbivore-induced plant volatiles (HIPVs), olfactory responses of frugivorous or nectarivorous birds remain underexplored. The predominance of studies in temperate regions further limits our understanding of bird olfaction in bird species-rich tropical areas. The detection of general traits of bird olfactory behaviour is difficult especially because of varying methodological approaches and lack of detailed information on bird and odour characteristics. Future research should distinguish between innate and learned olfactory behaviours, address the impact of environmental noise and consider individual and sex-specific differences in response to volatile compounds. Intensifying the consideration of these aspects will improve and deepen our knowledge of bird olfactory foraging behaviour and allow for ecological applications for targeted pest management and fruit dispersal strategies.</div></div>","PeriodicalId":50788,"journal":{"name":"Animal Behaviour","volume":"222 ","pages":"Article 123075"},"PeriodicalIF":2.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143738085","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}

We found no sign of individual identity across the two body areas sampled; samples from the facial region and samples of the anogenital region from the same individual were not similar to each other, suggesting that these regions carry different information. However, chemical profiles varied significantly by sex and breeding status; female breeders differed from nonbreeders in their anogenital profiles and had higher chemical diversity in their facial profiles compared with both males and nonbreeders. Interestingly, we found no signals of social group identity. Instead, individual identity may be conveyed through signature mixes that are learned through frequent contact, rather than through specific odours associated with genetic kinship or social group membership.
