Coleoid cephalopods exhibits the individual variation of lateralisation and temperament traits, but it is unrevealed whether there are associations between them. This study investigated whether visual lateralization is associated with temperament traits in oval squid <em>Sepioteuthis lessoniana</em> that exhibits individual variation of visual lateralization. The visual lateralisation was tested for eye preference against prey, predator, and conspecifics. The temperament traits were tested for activity, aggressiveness, exploration-avoidance, shyness-boldness, and sociability. Although activity, aggressiveness, exploration-avoidance, and shyness-boldness showed between-individual consistency, sociability did not show this trend. Moreover, there was not association among temperament traits, suggesting that these traits are independent. The direction of visual lateralisation (left or right) against prey, predator, and conspecifics was positively associated with aggressiveness, exploration-avoidance, and shyness-boldness. The strength of visual lateralisation (stronger or weaker) against prey was positively associated with aggressiveness. We discuss what those associations play a role in oval squid.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"228 ","pages":"Article 105206"},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898805","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}

Twenty-six hybrid fish were used, with 13 exhibiting normal color patterns (WT) and 13 showing greenish color patterns (G-WT). No difference was observed in locomotor in the novel tank patterns (average speed, distance traveled) and open field (homebase occupation and exploration) tests between the WT and G-WT groups. G-WT zebrafish presented higher anxiety-like behavior in the novel tank (increased time spent at the bottom). In the sociability test, the G-WT group spent less time in the conspecific area and kept higher distance from the social area, indicating reduced sociability compared to WT zebrafish. In conclusion, our results suggest that the hybridization between genetically modified and wild zebrafish may impact population dynamics, compromising social stability and increasing individual stress levels.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"228 ","pages":"Article 105203"},"PeriodicalIF":1.3,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143918026","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 aimed to elucidate how distinct anxiety modulators influence thigmotaxis over time and thrashing behavior. For this, adult zebrafish (<em>Danio rerio</em>) were submitted to the morphine (1.5 mg/L) withdrawal protocol (MOR) and acute conspecific alarm substance (CAS) at 3.5 mL/L for 5 min as anxiogenic exposures.

Then, fish were individually transferred to a 10-min OFT trial, with posterior analysis of behavioral activity. While MOR responses comprised hyperactivity, higher thigmotaxis, and increased thrashing, CAS showed heightened total immobility. ETOH exposure decreased time spent and distance traveled in the periphery, thrashing behavior, and locomotion. FLU group spent less time in the periphery, showing decreased thigmotaxis and thrashing. Pearson analyses contributed to elucidate how endpoint data correlate to each other, reinforcing the distinct responses observed. Overall, our study reinforces the differential effects evoked by anxiogenic and anxiolytic protocols regarding thigmotaxis.

Previous research has highlighted the impact of ungulates on disturbing grassland insects, leading to increased foraging success for Cattle Egrets. However, the risk-benefit relationship from an anti-predator perspective remains underexplored. This study, conducted in Yang County, Shaanxi Province, China, focused on Cattle Egrets and compared the foraging efficiency and flight initiation distance (FID) when foraging alongside cattle (<em>Bos</em> spp.) <em>versus</em> foraging alone. Additionally, our study analyzed the impact of increasing cattle numbers on the FID to assess whether foraging with cattle enhances the perceived safety. We hypothesized that, with more cattle, Cattle Egrets would be less vigilant if they can gain vigilance advantages from cattle. The results indicated significantly higher foraging efficiency and lower FID for Cattle Egrets when foraging with cattle compared to foraging alone, suggests that the presence of cattle enables Cattle Egrets to better tolerate potential predation risks. However, more cattle did not significantly affect the FID, indicating that the perceived predation risk of Cattle Egrets did not reduce with more cattle. The lower FID of Cattle Egrets when foraging with cattle is more likely attributed to higher foraging efficiency rather than lower perceived predation risk in their risk-benefit trade-off.

In this study, we examine learning and memory abilities from an ecological perspective by comparing Brandt’s voles (<em>Lasiopodomys brandti</em>) with Kunming mice (<em>Mus musculus</em>) using complex maze tests.

For long-term memory (LTMR), Brandt’s voles demonstrated consistently better retention across all time points, reflected in lower TTT and NEI. While short-term forgetting rates (STFR) were comparable between species, long-term forgetting rates (LTFR) indicated that Kunming mice exhibited higher rates of memory loss over extended periods than Brandt’s voles, with male mice exhibiting higher rates of memory decline than females. Overall, the findings suggest that Brandt’s voles possess enhanced spatial learning and long-term memory capacities, likely reflecting adaptations to their living condition.
