To increase the likelihood of detecting an odour molecule, individuals may exhibit anemotaxis – orientation bias to wind during movement – where the theoretical optimal olfactory search strategy is to move crosswind. We tested for biased movement relative to wind in Arctic grizzly bears (<em>Ursus arctos</em>) during the spring hypophagic period in the Mackenzie Delta, Northwest Territories, Canada using modelled winds and satellite-linked telemetry data (n = 12,430 locations) from 40 Arctic grizzly bears monitored between 2003 and 2010. Our results show that orientation relative to wind varied with movement rate, a proxy for active search effort. During steps where bears had high movement rates (> 90th percentile), bears predominantly oriented crosswind. We also found a positive relationship between movement rate and crosswind orientation: as bears moved faster, they increased their crosswind component of orientation. These results suggest an adaptive pattern of movement in response to wind, where bears oriented relative to the wind in a way that increased the likelihood of odour detection during active search. We suggest that future studies could include wind data in habitat selection and foraging models to examine its influence on habitat selection and use.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"227 ","pages":"Article 105177"},"PeriodicalIF":1.3,"publicationDate":"2025-03-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143656174","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Experimental trials are one tool that may provide insight to species-specific tolerance to elevated temperatures. We ran experimental trials to examine the effects of elevated temperature on Pacific sand lance <em>(Ammodytes personatus)</em>, an important forage fish in the North Pacific. Fish were held in tank trials at ambient (11 °C) and elevated (18 °C) temperatures in tanks with and without sediment. Analyses compared the effect of increased sea temperature on activity level, condition, and mortality. Experimental trials also examined the influence of the presence/absence of sediment on behavior. To compare experimental results with conditions experienced in situ, we evaluated a comparison dataset from the Salish Sea that spanned the 2014–2016 marine heat wave in the North Pacific. Analysis of in situ data showed a reduction in condition of Pacific sand lance populations in the Salish Sea during the 2014–2016 period of anomalous warming, but also recovery. Experimental trials demonstrated the importance of both temperature and sediment. Elevated temperatures resulted in reduced activity, reduced condition, and increased mortality. Absence of sediment had a negative effect on fish condition and survival and interfered with behavior associated with estivation and winter dormancy. Results provide insight into energetics and mortality that might be associated with future marine heat waves and have application to parameterizing ecosystem models.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"226 ","pages":"Article 105169"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143536586","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}

Cognitive performances are typically measured under laboratory conditions, in which individuals cannot observe others. Under natural conditions, however, observational learning would allow individuals with poorer cognitive abilities to improve their performance by copying the choices of more skilled individuals. Learning in groups would thus reduce differences in individual performance and, as such, might contribute to maintaining variability in cognitive abilities. Here, we carried out an experiment with zebra finches (<em>Taeniopygia guttata</em>) that were subjected to 3 associative learning tests, differing in terms of access to and complexity of public information. We found that the difference in learning performance between the fast and slow learners in the individual learning task was no longer significant when the slow learners had access to public information, but only if they received the same reward as their partner when choosing the same option. Thus, our study confirms that zebra finches tend to copy others’ decisions that perform better, and hence strongly suggests that individual variation in cognitive performance, when tested in isolation, may not accurately reflect actual foraging success in a natural social setting. In species that forage in groups and use social information, our findings thus might contribute to explaining i) the maintenance of individual differences in cognitive abilities, and ii) why cognitive performances are not necessarily used as mate choice criteria. To better understand the evolution of animal cognition, future studies will thus need to identify which are the relevant cognitive abilities on which selection may act and measure individuals’ cognitive performance in their natural environment.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"226 ","pages":"Article 105170"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143527235","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 analyzed recordings of songs from six adult male budgerigars with or without imitations of Japanese words to identify whether songs with imitations differed in structure from those without imitations. Songs with imitations contained significantly fewer narrowband syllables and more harmonic syllables, including imitative vocalizations, than those with no imitations.

In this study, we sought to assess the combined utility of reduced locomotor activity and freezing time as a dual-measure for a more accurate evaluation of the fear response in Sprague-Dawley rats. Both cued and contextual conditioning paradigms were employed. Behavioural outcomes were meticulously recorded via a state-of-the-art, fully automated Multi-Conditioning System. The results indicated a significant correlation between freezing time and diminished locomotor activity, underscoring that both measures represent congruent facets of the fear response. Each conditioning paradigm led to a notable reduction in locomotor activity in response to the conditioned cues. A pivotal insight from our findings is the risk associated with solely relying on freezing time, which could inadvertently overlook animals manifesting alternate fear responses. Conversely, gauging reduced locomotor activity facilitates a more precise discernment of animals that are genuinely resilient to fear conditioning. Our research champions the concurrent assessment of reduced locomotor activity and freezing time as a refined method to interpret fear response in rodents, particularly for identifying animals that exhibit fear-related behaviors but do not meet traditional freezing thresholds, promising to bolster the integrity of fear conditioning investigations and offer a deeper insight into fear behaviours.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"226 ","pages":"Article 105176"},"PeriodicalIF":1.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143578482","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}
