These features might create challenges for an effective intraspecific communication and potentially lead to misunderstandings during intraspecific interactions. This study aimed to investigate potential differences in behavioural displays during intraspecific approaches between dogs of different morphotypes: hunting dogs and shepherd dogs (mesocephalic morphotype) and small companion molossoids and guard molossoids (brachycephalic morphotype). Fourteen brachycephalic dogs and sixteen mesocephalic dogs were tested. We predicted that mesocephalic and brachycephalic would express facial signals at different extent and that if brachycephalic dog facial signaling is impaired by their facial conformation it could elicit different responses in the opponent dog. Contrary to our predictions, no behavioural differences were found between brachycephalic and mesocephalic breeds, suggesting that extreme conformation of brachycephalic dogs has not drastically altered their communicative abilities. Further results showed that the “tongue flicking” behaviour, previously suggested to function as an early warning in conflicted/aggressions-related contexts was performed more by mesocephalic TESTED DOGS when the DOG STIMULUS was a brachycephalic dog, suggesting that this morphotype can elicit intense and ambiguous response in mesocephalic dogs. Conversely, the “bow” behaviour, a stereotyped cue consistently found in canids intraspecific social contexts, was expressed more by the mesocephalic TESTED DOG towards other mesocephalic approaching DOG STIMULI. Different behavioural patterns associated to the specific breed types tested emerged: shepherd dogs showed higher alertness and dog orientation, hunting dogs barked more, guard molossoids showed calm vigilance and small companion molossoids were more avoidant in regards of the dog approaching them. The present study is the first aimed to examine if the brachycephalic morphotype influences dogs’ intraspecific communication and due to the limited number of dogs tested further experimental evidences are needed. Nevertheless, it appears that brachycephalic dogs are perceived differently by non-brachycephalic ones and these results could provide valuable insights for researchers, breeders and dog trainers.</div></div>","PeriodicalId":8222,"journal":{"name":"Applied Animal Behaviour Science","volume":"291 ","pages":"Article 106720"},"PeriodicalIF":2.2,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482449","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The present research focuses on a year-long study (2022–3) of the behavioural patterns and habitat preferences of a successfully breeding captive group of ten <em>Varecia</em> under naturalistic conditions at Fota Wildlife Park, Cork, Ireland. Focal and scan sampling were used to examine the effects of a series of factors such as time, daylight duration, temperature and visitors on the behavioural repertoire and activity budget to help elucidate which factors may influence behaviour and thereby enhance management options and breeding success. The results reveal that the activity budget of this captive <em>Varecia</em> group was similar to that of their wild counterparts, with the exception of a higher level of self-directed (9 %) and affiliative behaviours (20 %). Juveniles engaged in affiliative behaviours 112 % more than subadults, while adults spent 60 % more time being inactive than juveniles. Behaviours of the group changed significantly across the day and also across the year, with locomotion significantly decreasing as daylight hours lengthened and affiliative behaviours decreasing as temperatures rose. The most utilized area of the captive <em>Varecia</em> was the naturalistic island (39 %) and an out-door mesh tunnel (33 %). Locomotion was significantly higher on the island, while the tunnel had greater occurrences of affiliative behaviours. Visitor numbers had a significant influence on the utilization of all habitats, with higher visitor numbers near the island and tunnel increasing the use of the tunnel, while higher visitor numbers near the viewing window prompted greater utilization of this inside off-exhibit cage.

It provides farm and catch welfare profiles (WelfareChecks) of aquatic species based on literature reviews. In the catch branch, each WelfareCheck encompasses a species in relation to a specific fishing method used to catch it, assessing 10 criteria covering welfare hazards throughout the steps of the catching process: prospection, setting, catching, emersion, release from gear, bycatch avoidance, sorting, discarding, storing, and stunning/slaughter. In each criterion, we assess the likelihood and potential of experiencing good welfare under minimal and high-standard fisheries conditions, respectively, besides the certainty level about these. A final WelfareScore is provided for each profile, which serves as a benchmark for assessing and improving fish welfare. Since its publication in 2023, we have published five WelfareChecks. The goal is to increase the number of profiles for several fished species and catching methods over time. In conclusion, the catch branch of the fair-fish database serves as an open-access source providing an overview of the welfare of a fished species given a certain catching method. It is a reliable tool that raises public awareness of fish welfare, provides scientists with insight into knowledge gaps, and offers practitioners with suggestions about how to avoid welfare risks.</div></div>","PeriodicalId":8222,"journal":{"name":"Applied Animal Behaviour Science","volume":"291 ","pages":"Article 106732"},"PeriodicalIF":2.2,"publicationDate":"2025-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144489857","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The issue of their welfare during these interventions, however, remains insufficiently explored. The common practice of holding a rabbit on the client’s lap often leads to signs of stress. An alternative could be the use of a therapeutic table which allows for partial movement and provides a hiding place. This study aimed to analyze rabbits’ behavior during AAI and determine whether the therapeutic table represents an appropriate compromise for ensuring their well-being, or whether a no-contact approach with the client would be more suitable. The study included 9 female domestic rabbits habituated to human handling and 4 children, aged 9–11 years, unknown to the rabbits. A randomized controlled within-subject design with repeated measures was used. Each rabbit was tested twice in two different conditions: either on a specially adapted table with a hiding place in the presence of a child or without the presence of a child. A total of 36 sessions, each lasting 10 min, were conducted. The use of the hiding place, exploratory behavior, and feed intake were monitored, with all sessions video-recorded and later analyzed using Observer XT software. Statistical analysis was performed using R software (version 4.3.3; unction <em>glmer</em> in lme4 package and <em>nlme</em> package). The results showed that the rabbits spent on average three times more in the shelter during therapeutic sessions when a child was present compared to sessions without a child (F<sub>1,34</sub> = 2.051; p = 0.051). Rabbits displayed exploratory activity significantly less (F<sub>1,34</sub> = 6.308; p &lt; 0.0001) in the presence of a child, whereas in his absence, this time increased. Additionally, we observed a significant reduction in feed intake: in the presence of a child, the rabbits ate in less than 20 % of the observation time, while in the control group, feed intake was recorded in more than 80 % of the observation time (F<sub>1,34</sub> = 2.709; p = 0.007). The findings suggest that even though the therapeutic table provided hiding opportunities and allowed for movement, it did not fully mitigate the negative impact of the unfamiliar child’s presence on the rabbits’ welfare during AAI.

This research evaluated time-activity budgets of six goose species located at two UK Wildfowl &amp; Wetland Trust (WWT) centres, comparing captive population behaviours with two species of wild goose. Using a standardised ethogram and instantaneous focal sampling, we recorded over 220 h of behavioural data across 892 observations. All data were recorded in spring and summer of 2015, 2017 and 2018. Data were analysed using linear mixed models and zero-inflated models to account for high frequencies of zero occurrences in alert and social behaviours. Results show that whilst captive and wild geese broadly perform similar species-typical behaviours, captive birds exhibited higher levels of resting and lower social engagement. Foraging and locomotion differed significantly by species, and this may be a factor of ecological niche. Minimal stereotypic behaviour (&lt;2 % of observations) was recorded in the captive birds, suggesting that the large, naturalistic enclosures provided by WWT support positive welfare by enabling appetitive behaviours, such as grazing. However, high inactivity rates highlight the need for further enrichment and dynamic enclosure management to be considered to further improve goose behavioural diversity. Comparisons with wild geese provide useful benchmarks for evaluating behavioural normality under human care. This research supports the use of time-activity budgets as a practical tool for developing evidence-based, species-specific husbandry guidelines.

Common approaches to horse training are largely based upon traditional practices, which frequently do not align with equine telos, ethology or cognition, and consequently, the techniques used to facilitate human-horse interactions warrants this concern. Given the current pressure on equestrianism’s social licence, it is timely to review what is currently known about equine behaviour modification approaches and identify areas where there is a deficit of knowledge. Uniquely in horse training, negative reinforcement is the fundamental basis for the majority of human-horse interactions, compared to the wider reliance on positive reinforcement in other animal species. While positive reinforcement offers many advantages for animal training, the characteristics of the ridden horse interaction necessarily relies on the use of aversive stimuli during training, such as pressure cues, even if of low intensity. Therefore, the question of whether a combined reinforcement model, incorporating both positive and negative reinforcement, can provide the benefits of positive reinforcement while accommodating pressure cues from negative reinforcement is worth investigating. This review seeks to outline current knowledge and application of combined reinforcement in the equine training literature for comparison with positive and negative reinforcement modalities. A survey of the literature highlighted a large number of inconsistencies in the description and classification of different forms of reinforcement used in training. Many studies putatively exploring positive reinforcement incorporate unacknowledged aspects of negative reinforcement, thereby confounding experimental outcomes and the interpretation of the results. Consequently the lack of specific focus on how these approaches actually consist of combined reinforcement has meant opportunities to advance scientific understanding in this area have been missed. As a result, knowledge of combined reinforcement remains poor, whilst training approaches and outcomes arising from positive reinforcement are inconsistent or incorrectly classified. These inconsistencies highlight the need for targeted research on the use of combined reinforcement, to better understand how to incorporate rewards-based training programs in horse training, including during riding.</div></div>","PeriodicalId":8222,"journal":{"name":"Applied Animal Behaviour Science","volume":"291 ","pages":"Article 106718"},"PeriodicalIF":2.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144482451","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Relevant studies were sourced from PubMed and Google Scholar. Inclusion criteria required articles published between 2004 and 2024 that reported the presence or association of behavioural disorders with physical diseases and were either research articles or case reports. Exclusion criteria were review articles, conference proceedings, books, and articles without full-text access. For the meta-analysis, at least three studies with similar methodologies were required. Three independent researchers reviewed the data to minimise bias, and article quality was assessed using established guidelines for systematic reviews. Publication bias was evaluated using Fail-safe-N analysis and a rank association test for funnel plot asymmetry. Data were recorded in Microsoft Excel 365 and analysed using the meta-analysis package in Jamovi software. Of the 14,267 articles identified, 29 met the criteria for the systematic review, and 4 were included in the meta-analysis.
