We studied exploratory and sheltering behaviour in the crayfish F. virilis to understand how these behaviours vary by sex and reproductive readiness and to quantify the repeatability of these behaviours. Crayfish were tested in two sets of three rounds, one in the summer non-reproductive season and another in the autumn reproductive season. Reproductive crayfish spent more time outside the shelter and were more likely to accept a food item than non-reproductive crayfish. In the non-reproductive season, females spent more time outside the shelter than males, and over both seasons, females were more likely to seek and accept a food item. Repeatability estimates were low, indicating high intra-individual variability in these behaviours. Sheltering and exploratory behaviours were not correlated. This indicates sex or reproductive readiness have strong effects on both sheltering and exploratory behaviours.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44554772","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}

MIH is now widely accepted as fact by the general public and some sections of the scientific community despite remaining unproven. This hypothesis assumes that ‘mistaken’ shark bites on humans result primarily from confusing visual cues and ignores the important role of other senses (e.g. hearing) in discriminating potential prey. A far simpler ‘natural exploration’ hypothesis can reasonably explain not only shark bites that have been characterized as ‘mistaken identity’ events but also those that cannot be reasonably explained by MIH (e.g. shark bites that occur in very clear water). Simply stated, sharks don’t make ‘mistakes’ but instead continually explore their environments and routinely investigate novel objects as potential prey by biting them.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44932622","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 response to predators further away, Western Australian magpies (Gymnorhina tibicen dorsalis) produce alarm calls containing fewer notes compared to those produced when predators are closer. Since the ability to make fine-scale adjustments to antipredator responses by being sensitive to the level of urgency in calls may be beneficial, receivers are expected to be able to appropriately decipher and respond to this information. We conducted playbacks to test whether magpies can respond to urgency information in conspecific alarm calls. Magpies were exposed to low-urgency calls (calls with one note), high-urgency calls (calls with four notes), and one- and four-note control calls. Receivers showed greater levels of responsiveness following playbacks of high-urgency calls compared to playbacks of low-urgency and control calls, providing evidence that magpies can respond to information about the urgency of a predator threat from conspecific alarm calls.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44818101","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 proposed two non-mutually exclusive hypotheses; the optimal density model (ODM) and the habitat structure hypothesis (HSH). The ODM proposes that animals utilize low cache density to protect their valuable caches by transporting food far from food sources. The HSH proposes that animals utilize predation risk to protect their valuable caches by hoarding food in open areas. Here, we investigated the hoarding behaviours in Eurasian red squirrels Sciurus vulgaris by experimentally providing high-quality (walnuts) and low-quality (acorns) food, to examine if they follow ODM or HSH. Compared to acorns, squirrels hoarded walnuts in places further from the area where food was provisioned and in areas with low canopy cover. These results agree with both ODM and HSH, providing the first evidence that hoarding behaviour in Eurasian red squirrels is shaped by multiple factors.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46084847","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 characterized female preferences for the advertisement songs of male Alston’s singing mice (Scotinomys teguina). We developed procedures for inducing oestrus, using vaginal perforation as a morphological indicator of oestrus. We then broadcasted ‘high-effort’ and ‘low-effort’ songs recorded from wild-caught males to virgin laboratory-reared females, using a two-choice experiment. Our results indicate that females spent more time investigating speakers playing high-effort songs; surprisingly, this phonotactic response is independent of oestrus status. In wild singing mice, acoustic characteristics of high-effort male songs positively correlate with body condition. Our data suggest that females could use acoustic cues to select mates in good condition, thus providing preliminary support for adaptive mate choice hypotheses. More generally, our results support the hypothesis that elaborate Scotinomys song may be shaped by female choice.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48477496","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}

Chronic social defeat has been found to alter the emotional and social behaviours, whether it affects partner preference remains unclear. Using monogamous mandarin voles (Microtus mandarinus), the present study found that 14 days of social defeat to male vole could increase social avoidance in sociality test, and reduced attacking, intimate, sniffing and exploratory behaviours, but increased avoidance defensive, immobile behaviours in social interaction test. In addition, this treatment significantly reduced side-by-side contact with partner throughout cohabitation period, and reduced the attacking behaviour to strangers after 11 days’ cohabitation. Furthermore, in mandarin vole with chronic social defeat, partner preference was abolished on 5 and 7 days’ cohabitation indicating that pair bonding stability was impaired by chronic social defeat. Moreover, although mandarin voles spent longer time rescuing partner than stranger in both groups, chronic social defeat did not affect rescuing significantly. Impairment of pair bonding may be due to abnormalities in social interaction induced by chronic social defeat. This finding provides some insights into mechanisms underlying effects of prolong social stress on social relationships between partners.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-02-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41622536","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}

Autotomy is expected to indicate that individuals have escaped from predators. The incidence of leg autotomy in the cricket Dianemobius nigrofasciatus was compared between urban and rural habitats. The incidence of autotomy was higher in urban than in rural habitats. Failure to moult and conspecific aggressive interactions were not the main factors contributing to the incidence of autotomy in these crickets.

However, little is known about the influence of personality on novel food preferences in the social context, i.e., whether knowledge and previous experience can influence individual preference or if the presence of conspecifics can alter their choice. In the present study, we examined in cinereous tit (Parus cinereus) whether individuals with different personality types in the social context will prefer their own previously chosen novel food or change their preference in the presence of conspecifics. Second, we studied how the presence and behaviour of conspecifics may mediate individual personality. We conducted a standardized personality assay (exploratory behaviour) to analyse the individual personality. Birds were trained and provided with three different types of novel human-derived materials in both asocial and social contexts (with a conspecific). We recorded the latency to feed, time spent at the feeder, and the number of visits by fast and slow explorers in the two contexts, i.e., asocial and social. After the analyses of experimental data, we found that fast-exploring cinereous tits preferred peanuts in an asocial context, while slow explorers consumed a greater amount of sunflower seeds. In the social context, individuals of both personality types preferred peanuts to sunflower seeds. Additionally, individuals took less latency to eat food, made more visits to the feeder, and spent more time at the feeder in the social context than in the asocial context. Our findings show that foraging success may be determined by personality and social context. However, personality traits may be subject to constraints arising from correlations with other behavioural traits, and it remains a major challenge to understand the functional significance of individual foraging strategies.","PeriodicalId":8822,"journal":{"name":"Behaviour","volume":null,"pages":null},"PeriodicalIF":1.3,"publicationDate":"2023-01-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41458628","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}
