One of the best known is unkenreflex. It was described for the first time in Firebellied Toads <i>Bombina</i>; spp. and it is, in its classic form, a display of conspicuous underside by lifting limbs and arching back upon disturbance. Unkenreflex has also been recorded in other anurans, but its prevalence across species has not been extensively studied so far. Here, we present our own observations and review published records, distinguishing full and partial unkenreflex. We document 23 cases of unkenreflex, including the first records in <i>Pelobates fuscus</i>, <i>Bufotes viridis</i>, <i>Bufo bufo</i>, <i>Pelophylax esculentus</i> complex, and <i>Hyla arborea</i>. Combining these findings with previously published records, in 43 species partial unkenreflex has been reported, in 34 species full unkenreflex, while both types were observed in seven species. Regarding family and biogeographic realm, the True Toads (Bufonidae) and Neotropics had the highest number of species in which unkenreflex was reported. Our review clearly shows that unkenreflex is more widespread among anurans than previously thought. Full unkenreflex likely conveys survival advantages through aposematism and deimatism, while partial reflex may rely on mechanisms such as protecting eyes, increasing body width to deter swallowing, obscuring head location, and feigning death (thanatosis). Robust large-scale sampling and experiments are needed to fully elucidate the prevalence, role, distal mechanisms, and evolution of this fascinating and understudied behaviour.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 2","pages":"77 - 84"},"PeriodicalIF":1.3,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171112","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}

Due to the relevance of animal behaviour in predicting and mitigating the impacts of environmental changes on populations and ecosystems the interdisciplinary field of Conservation Behaviour has recently emerged. While it was formally acknowledged as a discipline about 30 years ago, it was only in 2011 that a theoretical framework was proposed by Berger-Tal and colleagues. Currently, numerous examples illustrate the use of animal behaviour in conservation and management efforts. However, most of these examples involve terrestrial animals. This is partly because both the behaviour and habitats of terrestrial animals are more accessible than those in the marine environment. Here, I provide an overview on how animal behaviour can contribute to marine conservation, namely in assessing anthropogenic impacts on animal behaviour, using behaviour as indicators and in guiding conservation and management interventions, using examples from the marine environment. Finally, I discuss future directions and how major technological advances in equipment and in artificial intelligence can be critical for developing effective conservation strategies and policies in a rapidly changing world.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 2","pages":"67 - 75"},"PeriodicalIF":1.3,"publicationDate":"2025-04-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-025-00460-4.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145167549","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}

One of the main critical gaps in understanding rodent sociality is the role of subadult individuals prolonging their stay with parents and younger siblings, particularly in nocturnal and elusive species. Moreover, urban environments are known to elicit changes in the social behaviour of mammals, leading to altered patterns of sociality. Yet, little is known on how rodent societies may change in altered environments. Thus, we aimed at investigating the social behaviour of the crested porcupine <i>Hystrix cristata</i> in central Italy, with a particular focus on group composition and on the prolonged occurrence of subadult individuals within family groups. We also tested the potential effects of natural and urban environments. We combined marking of free-ranging individuals with camera trapping campaigns across three ecologically contrasting areas, and showed a pair-living social system for adult crested porcupines. Most videos captured either single young individuals or pairs of adults. Subadult marked females were observed together with adults during the birth season in the year following their birth, suggesting a potential helping role. Conversely, subadult marked males were rarely observed, presumably dispersing. Groups exceeding two individuals ranged between three and five, and were typically observed following reproductive events, with porcupines commuting in line, parents positioned at head and tail of the row. Urban environments showed a slightly different pattern, with occasional aggregations of subadults. We highlight the importance of understanding subadult behaviour in crested porcupines, as well as of testing the effects of urban ecosystems upon mammalian social systems. These findings contribute to a broader understanding of social behaviour and evolutionary adaptations in rodents and, more in general, of mammals.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 2","pages":"109 - 117"},"PeriodicalIF":1.3,"publicationDate":"2025-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-025-00459-x.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145162330","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}

Studies investigating the negative impacts of acephate in animals have used zebrafish larvae as a model species, but the effect on adult individuals remains unclear. Our main objective was to assess the behavioural changes in adult zebrafish (<i>Danio rerio</i>) exposed to acephate and methamidophos. To this end, 160 individuals of zebrafish were divided into three groups: acephate, methamidophos (exposed) and control groups (non-exposed), where subjects in the treatment groups were exposed to 7 µg/L of acephate and 7 µg/L methamidophos for 28 days. To compare the groups, behavioural assessments were conducted using scan sampling with instantaneous behaviour recordings every 30 s for ten minutes each day. Fish behaviour and fish location in the water column were compared between treatment and controls using Generalized Linear Mixed Models. The results showed an alteration in swimming patterns, an increase in aggression, an increase in abnormal behaviours and other stress-related behaviours, such as gasping for air, provoked by acephate and methamidophos. These behavioural alterations may have serious consequences for wild fish communities, such as an increased risk of predation and may contribute to the extinction of local populations. These findings highlight the usefulness of behaviour in assessing the environmental impact caused by pesticides.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 2","pages":"95 - 107"},"PeriodicalIF":1.3,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10211-025-00456-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145171055","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}

In terrestrial ecosystems, humans are the major predators of wild cervids (Cervidae, Cetartiodactyla, Mammalia) in regions where large carnivores have gone extinct due to anthropogenic persecution. Typical anti-predator behavior exhibited by wild cervids includes increasing nocturnality and vigilance. We investigated diel activity and vigilance in sika deer (<i>Cervus nippon</i>) in nonhunting areas using camera-trapping techniques, to determine whether human visitation (i.e., nonlethal effects) increases their nocturnality and vigilance. We established two study sites––inside (low risk) and outside (high risk) of a wildlife reserve at University of Tokyo Chichibu Forest, Saitama, Japan. We hypothesized that in sika deer, nocturnality and vigilance would increase at high-risk site (outside of the reserve), due to the high rate of human visitation. However, vigilance level and diel activity between the two study sites were not different. In female deer, vigilance increased in winter regardless of the site studied. Our findings suggest that hunting activities (e.g., drive hunting with dogs) outside of the studied areas triggered anti-predator behaviors, such as increased vigilance, in sika deer, although our studied sites were not designated as hunting area. Further studies need to elucidate what types of human activities and intensity levels trigger anti-predator behaviors by wild ungulates.</p></div>","PeriodicalId":6879,"journal":{"name":"acta ethologica","volume":"28 1","pages":"27 - 37"},"PeriodicalIF":1.1,"publicationDate":"2024-12-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143362023","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}
