Initially, food was placed in the funnel in the first two visits, while on the subsequent three visits, the resource was only offered after the wasp entered the device through the funnel. Our results showed that foragers chose the funnel to enter the Y-maze in search of food. Interestingly, on successive visits, when no food was offered, foragers learned to enter the device more rapidly. In sum, the present research reveals that these wasps exhibit diverse learning capabilities, suggesting that their responses can be modified by the consequences they experience.

Zebrafish responds to anxiogenic and anxiolytic protocols in the OFT, but the influence of such manipulations on the habituation process is still unclear. 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. For anxiolytic treatments, we selected acute ethanol (ETOH) at 0.5 % (v/v) for 1 h and acute fluoxetine (FLU) at 100 µg/L for 15 min. 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. Moreover, our results suggest that thrashing behavior configures a valuable tool to improve behavioral analyses in the OFT, contributing to further in-depth investigations related to distinct anxiety-like states.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"228 ","pages":"Article 105199"},"PeriodicalIF":1.3,"publicationDate":"2025-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143847620","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}

These abilities enhance competitiveness and fitness by supporting navigation, resource acquisition, and predator avoidance. Understanding how spatial learning and memory vary among species with different living conditions can provide insights into the evolutionary pressures shaping these skills. 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. Brandt’s voles exhibited significantly shorter total task time (TTT) and fewer number of errors (NEI) compared to Kunming mice, highlighting superior spatial learning ability. Short-term memory (STMR) results revealed no significant differences between species as well as sex. 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. This study contributes to our understanding of species- and sex-related differences in spatial learning and memory, providing evidence for the ecological basis of these cognitive traits in response to environmental challenges.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"227 ","pages":"Article 105190"},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143825849","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 examine this question and hypothesize that female fiddler crabs can use natural male color variation as a parameter for partner selection. To investigate the preference of female fiddler crabs we set up an experimental arena in a mangrove area and presented female <em>Leptuca leptodactyla</em> (n = 100) with pairs (n = 100) of conspecific males. After registering a female’s choice, we quantified the natural reflectance (i.e., color) from the enlarged claw of each male, by using a spectrometer, and extracted their colorimetric parameters (i.e., brightness, saturation and hue). Our results showed that females significantly favored males displaying higher brightness and lower green saturation. We discuss the possibility that brightness and saturation are redundant properties of the examined trait, both conveying information about male individual quality to females.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"227 ","pages":"Article 105188"},"PeriodicalIF":1.3,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143760765","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}

The current study explores the vocal responsiveness to signals of diverse temporal structure under realistic conditions of stimulus broadcast, employing presentation rates observed in alternating interactions between pairs of males. The results show that aggressive patterns of response, measured as increased call duration, are specially consistent in exposures to stimuli of novel design, not related to natural vocalizations.
