The following pair of experiments investigated the acoustic and behavioral responses of California ground squirrels from the higher-elevation Sierra Valley (alt. ∼1900 m) and from the lower-elevation Sunol region (alt. ∼270 m). Analyses of their genetic distance suggest that these populations diverged during the Late Pleistocene. The first experiment compared small groups from these populations on the basis of their auditory brainstem responses (ABR) to a range of sound frequencies. The ABR audiograms of Sierra Valley squirrels showed greater acoustic sensitivity to frequencies lower than 4 kHz than the Sunol squirrels. Both groups exhibited similar audiograms for higher frequencies. Such an adaptation would be useful for coping with dangerous circumstances possibly masked by inclement weather. The second experiment compared the squirrel groups for several 9-hr observation periods focusing on the number of egress bouts from nest boxes centered in a laboratory room equipped with sound playback equipment to simulate far-field naturalistic sounds. Three sound treatments were compared: 1) ambient room sound, 2) temperate forest, and 3) rainstorm. Analyses indicated that the higher-altitude Sierra Valley squirrels were reliably less likely to leave the nestbox to explore the room than were low-altitude Sunol squirrels under the rain treatment. The results of both studies suggest that the enhanced low-frequency hearing of Sierra Valley squirrels is a sensory adaptation for coping with the reduced sound transmission of low frequencies at higher altitudes.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"235 ","pages":"Article 105323"},"PeriodicalIF":1.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145833061","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}

In this study, we compared aspects of cognition between captive and wild fathead minnow (<em>Pimephales promelas)</em> to investigate how life in captivity might impact traits essential to fitness in the wild. Specifically, we assessed aversive learning performance using an associative learning assay and a more complex reversal learning assay, and we also measured anxiety and brain mass. Performance in the associative learning task was negatively correlated with performance in the reversal learning task, suggesting a potential tradeoff. No differences were observed between captive and wild fish in associative learning performance, anxiety, or brain mass, but wild fish were three times more likely to complete the more complex reversal learning task. Aversive reversal learning, which appears to be dampened in captive fathead minnow, may be particularly relevant for appropriate antipredator responses and fitness in challenging or fluctuating environments.

Planaria are a potentially important animal model for the study of threat learning and memory as they can learn conditioned responses and may show conserved neural mechanisms underpinning these responses compared to mammals. However, no model for the study of memory in classical threat conditioning exists for planaria. The aim of this study is to replicate a standardised cued threat conditioning model for memory acquisition and reconsolidation in mice, in brown planaria (<em>Girardia dorotocephala</em>), using shock as the unconditioned stimulus (US) and light as the conditioned stimulus (CS). Defensive behaviours (C-shaped movements and scrunching) were assessed to evaluate learning. Planaria underwent memory acquisition training for a total of 18 learning trials. In the consolidation model, memory retention was tested 24 h after the final training session with a CS exposure. In the reconsolidation model, memory stability was assessed using a recall test 24 h after a reactivation session. In both tests, the paired shock-light group exhibited a significant increase in defensive behaviours, compared to all control groups, suggesting that the pairing of both shock and light was essential for forming a lasting memory. Furthermore, planaria exhibited a gradual extinction of defensive responses to the CS. These findings highlight the utility of planaria for studying associative learning and memory, including memory reconsolidation.</div></div>","PeriodicalId":8746,"journal":{"name":"Behavioural Processes","volume":"235 ","pages":"Article 105321"},"PeriodicalIF":1.5,"publicationDate":"2026-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145751461","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}

Previous studies have shown that this host exhibits strong aggressive behaviors toward common cuckoos.

We conclude that the nest defense intensity of oriental reed warblers against common cuckoos did not significantly change with different breeding stages between early incubation and nestling feeding stages.

Plastic sex roles can occur in response to environmental cues, such as when food and mate resources are limited. In dung roller beetles, the encounter of sexes occurs at the food source; males are commonly reported cutting, forming balls and attracting females. Intrasexual competition has been particularly associated with fights for mate acquisition among males, while females heavily invest in parental care. Here, we test the hypothesis that females have high motivation to compete for balls and mates due to the striking relevance of gaining fertilizations before nesting. This competition is expected to be more intense when the operational sex ratio is biased, affecting behaviors related to ball acquisition (ball production and fights for ball possession) and access to mates (male-female pair formation, courtship and mating). We used the Neotropical dung roller beetle <em>Canthon bispinus</em> and exposed males and females to two experimental groups differing in the operational sex ratio: Female and Male Bias group. We examined the proportion of successful trials for females and males. We found that males were very active in food search in both groups, while fighting with each other in the Male Bias group. In contrast, females became highly competitive, actively engaging in ball rolling and fights in the Female Bias group.
