The performance of elite athletes is at the forefront of attention in sports science, with a predominant focus on technical, physiological, mental, or contextual factors that can be leveraged to optimize athlete performance. Athletes’ off-sports activities, however, remain largely unexplored. What is it that elite athletes do in their off-sports time, and how are their off-sports activities related to sports experiences and outcomes? With this qualitative study, we aim to illuminate athletes’ off-sports activities and their implications for sports outcomes. We collected listings of off-sports activities from 46 professional soccer players and interviewed 15 elite speed skaters about their off-sports activities and their potential to enrich or interfere with their sports domain. The resulting category framework of off-sports activities comprises eight categories, reflecting social, cognitive, and physical off-sports activities. Next, the speed skaters described beneficial spillover experiences for active, high-effort mastery-oriented off-sports activities. However, such activities could also cause fatigue if not balanced with sufficient, more passive, restful activities. In all, athletes did experience spillover from non-sports to sports and their qualitative accounts reveal several antecedents, mechanisms, and outcomes of spillover, supporting the process view of the work–home resources (W-HR) model (Ten Brummelhuis & Bakker, 2012).

Technological enrichment, such as motion sensors, touchscreens, and response-independent feeders, offer innovative ways to enhance animal welfare in captivity by promoting species-appropriate behaviours and cognitive stimulation. A scoping review of 22 publications comprising 25 studies identified various technologies, with computers being the most common, and sensory enrichment the most frequent type implemented. Positive or neutral welfare outcomes were common, though some negative effects were also reported. Primates and carnivores were the most frequently studied groups. Despite increasing research since 2012, gaps remain, including limited peer-reviewed studies and a need for standardised methodologies to better evaluate the impact of technological enrichment.

This article investigates how anthropological knowledge about regions with economic difficulties became part of regional development in France during the pivotal decade of the 1970s. It argues that ethnological fieldwork in French peripheries in the 1960s provided knowledge about regional culture and practices for its maintenance that became the core of a new development tool, the Ecomusée. It was via this tool that French anthropologists sought to intervene in regional development. By analyzing one of the first French ecomuseums, we gain an understanding of how anthropological practices and knowledge nurtured the shift to cultural development politics associated with the “enrichment economy.” Fieldwork in the 1960s, aimed at a professionalized Ethnologie de France, problematized interaction with the local population and produced knowledge about regional culture that identified a region with its economic past. The practices of documentation and participation established during these fieldwork projects shaped the enrichment economy.

The popularity of keeping domesticated cats (Felis catus) indoor-only or outdoor-indoor varies according to geographical location, and both have risks and benefits. Walking cats (e.g. on leashes) may enable mitigation of roaming risks while providing outdoor access, but the practice of walking cats appears relatively uncommon and is yet to be examined in the literature. Semi-structured online interviews (21 participants across seven countries) were conducted to explore cat walking perceptions and experiences in owners who currently practise it. Interview recordings were transcribed and analysed using reflexive thematic analysis. Five main themes were generated: (1) Benefits of walking; (2) Challenges around walking; (3) Safety for walking; (4) Cat individuality and walking; and (5) Attitudes about walking across geographic contexts. Themes highlighted that participants perceived benefits of walking for both cat and owner but faced challenges largely due to dogs and their owners in addition to judgment from others in the community. The main priorities of walking were seen to be ensuring safety and attending to the individual needs of each cat. Reactions to cat walking appeared to vary according to local norms and attitudes about cats and owner-cat relationships. The subjective nature of both the concept and practice of cat walking was also emphasised. These findings provide an initial base for what the experience of walking cats can be like and highlight that further research to directly investigate the welfare impacts of walking on cats and their owners is now needed.

Environmental enrichment programmes are widely used to improve welfare of captive and laboratory animals, especially non-human primates. Monitoring enrichment use over time is crucial, as animals may habituate and reduce their interaction with it. In this study we aimed to monitor the interaction with enrichment items in groups of rhesus macaques (Macaca mulatta), each consisting of an average of ten individuals, living in a breeding colony. To streamline the time-intensive task of assessing enrichment programmes we automated the evaluation process by using machine learning technologies. We built two computer vision-based pipelines to evaluate monkeys’ interactions with different enrichment items: a white drum containing raisins and a non-food-based puzzle. The first pipeline analyses the usage of enrichment items in nine groups, both when it contains food and when it is empty. The second pipeline counts the number of monkeys interacting with a puzzle across twelve groups. The data derived from the two pipelines reveal that the macaques consistently express interest in the food-based white drum enrichment, even several months after its introduction. The puzzle enrichment was monitored for one month, showing a gradual decline in interaction over time. These pipelines are valuable for assessing enrichment by minimising the time spent on animal observation and data analysis; this study demonstrates that automated methods can consistently monitor macaque engagement with enrichments, systematically tracking habituation responses and long-term effectiveness. Such advancements have significant implications for enhancing animal welfare, enabling the discontinuation of ineffective enrichments and the adaptation of enrichment plans to meet the animals’ needs.

Interplanetary spacecraft are built in a spacecraft assembly facility (SAF), a clean room designed to reduce microbial contamination that could confound life detection missions or influence native ecosystems. The frigid hyperarid near-surface environment of Mars has ample hygroscopic Mg and Na salts of chloride, (per)chlorate and sulphate that may deliquesce to form dense brines, liquids with low water activity, and freezing points <0°C. The current study sought to define the climax microbial community after 6 mo of enrichment of SAF floor wipe samples in salt plains medium supplemented with 50% (w/v; ~2 M; aw = 0.94) MgSO4 or 20% (w/v; ~1.9 M; aw = 0.91) NaClO3. After 1 wk, 4 wk and 6 mo of incubation, metagenomic DNA extracts of the enriched SAF microbial community were used for high-throughput sequencing of 16S rRNA genes and subsequent phylogenetic analyses. Additionally, dozens of bacterial strains were isolated by repetitive streak-plating from the climax community after 6 mo of enrichment. Early in the enrichment, staphylococci greatly dominated and then remained abundant members of the community. However, actinobacteria succeeded the staphylococci as the dominant taxa as the cultures matured, including Arthrobacter, Brachybacterium and Brevibacterium. A diverse assemblage of bacilli was present, with Oceanobacillus being especially abundant. The SAF culture collection included representatives of Brachybacterium conglomeratum, Brevibacterium sediminis, Oceanobacillus picturae and Staphylococcus sciuri. These were characterized with biochemical and physiological tests, revealing their high salinotolerance. Shannon diversity indices were generally near 2, reflecting modest diversity at several levels of identity and the community structures were uneven throughout. However, minor members of the community seem capable of the ecosystem functions required for biogeochemical cycling. For instance, organisms capable of all the functions of the N cycle were detected. The microbial assemblage in SAFs is the most likely to be transported by spacecraft to another world. While individual microbial populations may exhibit the qualities needed for survival at the near-surface of Mars, certainly entire communities with the capacity for complete biogeochemical cycling, would have a greater chance of survival and proliferation.

Prenatal stress is the mechanism through which poor welfare of pregnant sows has detrimental effects on the health and resilience of their piglets. We compared two gestation housing systems (IMPROVED versus [conventional] CONTROL) in terms of sow stress and welfare indicators and sought to determine whether potential benefits to the sows would translate into improved offspring health. Sows were mixed into 12 stable groups (six groups per treatment, 20 sows per group) 29 days post-service in pens with free-access, full-length individual feeding/lying-stalls. CONTROL pens had fully slatted concrete floors, with two blocks of wood and two chains suspended in the group area. IMPROVED pens were the same but with rubber mats and manila rope in each stall, and straw provided in three racks in the group area. Saliva was collected from each sow on day 80 of pregnancy and analysed for haptoglobin. Hair cortisol was measured in late gestation. Sows’ right and left eyes were scored for tear staining in mid lactation and at weaning. Numbers of piglets born alive, dead, mummified, and total born were recorded. Piglets were weighed and scored for vitality and intra-uterine growth restriction (IUGR) at birth. Presence of diarrhoea in farrowing pens was scored every second day throughout the suckling period. IMPROVED sows had lower haptoglobin levels and tear-stain scores during lactation. IMPROVED sows produced fewer mummified piglets, and these had significantly lower IUGR scores, and scored lower for diarrhoea than piglets of CONTROL sows. Hence, improving sow welfare during gestation improved the health and performance of their offspring.

There is some evidence that rats benefit from social housing and from some forms of environmental enrichment, such as platforms and shelters. It is less clear whether they benefit from more spacious cages. There is a lack of information about the relative benefits of social contact, enrichment and increased space, because existing studies tend to concentrate on only one of these variables at a time. The current experiment used economic demand procedures as a method to compare, on a single scale, qualitatively different environments with a standard home cage. The data indicate that rats show a high demand for social contact, and a low demand for a larger cage or one containing pillars or novel objects. This finding suggests that social housing of laboratory rats should be strongly advocated.

Many of Australia's nocturnal mammals are rare or endangered in the wild. The behavioural integrity of captive populations of endangered species can be maintained through the application of environmental enrichment techniques. This study investigated the effectiveness of feeding enrichment in promoting behavioural diversity, enclosure usage and species-typical behaviours in the ghost bat (Macroderma gigas) and the yellow-bellied glider (Petaurus australis). Animals were observed for 300 min day-1 over three consecutive time periods: baseline (12 non-consecutive days); enrichment: (12 consecutive days); and post-enrichment: (12 non-consecutive days). The use of a live insect dispenser decreased grooming and increased out-of-sight and social behaviour in the ghost bat. Artificial gum trees promoted species-typical behaviours in the yellow-bellied glider. Enrichment for nocturnal mammals had variable results and different welfare implications for these animals.

There is a growing awareness that non-human primates kept in zoos and laboratories deserve more species-appropriate stimulation because of their biological adaptation to a challenging environment.

Numerous attempts have been made to effectively emulate the gathering and processing aspects of natural feeding. Whole natural food-items, woodchips mixed with seeds, the puzzle ceiling and the puzzle feeder stocked with ordinary biscuits, cost little or nothing but induce sustained food gathering and/or food processing. Turf and fleece substrates sprinkled with particles of flavoured food, foraging trays, probe feeders and puzzles baited with food treats also promote more foraging behaviour, but they are relatively expensive and require added labour time to load and clean them.

As adult cats can often be difficult to re-home, they may spend long periods in rescue shelters where barren housing and inconsistent handling can reduce their welfare. In this study, 165 adult cats in an animal shelter in Vancouver, Canada, were assigned to four treatments. The Basic Single treatment reflected typical conditions in that particular shelter, with cats handled in an inconsistent manner by various staff and housed singly in relatively barren cages. Three alternative treatments involved more consistent, positive handling by only the experimenter and research assistants, plus three housing conditions: Enriched Single (individual cages with opportunities to perch and hide), Basic Communal (group housing with opportunity for each cat to have personal space), and Enriched Communal (group housing enriched to encourage play and cat – cat interaction). The Basic Single treatment had the lowest percentage adopted in 21 days (45% versus 69-76% for other treatment, and higher stress scores than other treatments. The three alternative treatments did not differ significantly on any measure. Cats euthanised for poor health showed higher stress levels when alive than other cats. In a questionnaire, most adopters cited certain behavioural/emotional traits (‘friendly’, ‘playful’, ‘happy’) as reasons for selecting cats; these were generally associated with lower stress scores. The results suggest that consistent handling combined with a range of improved housing options can improve the chances of adoption for adult cats, perhaps by reducing fear-related behaviours that make cats less attractive to adopters.

The barren housing conditions of farmed blue foxes (Alopex lagopus) provide few stimuli to motivate exploration and interaction with the physical environment. In the present study, wooden blocks (30x7 cm [lxdia]) were employed to clarify how such inanimate objects might serve to enrich the barren wire-mesh cages. Two separate experiments were carried out. In experiment 1, behavioural reactions of eight male blue foxes to wooden blocks were videotaped between January and May. In experiment 2, 16 male blue foxes were housed singly in cages with wooden blocks and 16 without between January and June. Pencil, confrontation, feeding and open field tests were carried out. Furthermore, 50 female blue foxes were kept singly in cages with wooden blocks and 49 without from January to July. Both groups were bred and the whelping result was recorded. In-cage behavioural tests were performed three times. Results showed that interactions with the wooden blocks were frequent, averaging 77 interactions fox’1 day1. Interactions with blocks decreased slightly with time. Blocks were mainly used for carrying, chewing, poking and sniffing. In the confrontation test, male foxes housed without blocks were more passive than those with blocks. No differences were found between the groups in the pencil, feeding or open field tests. Whelping success tended to be better for vixens housed with than without blocks. It can be concluded that wooden blocks have enrichment value by providing more choices for foxes in a barren cage and stimulating more variable behaviour.

The behaviour of 10 adult individually-caged male cats was measured either in their normal cage or with additional objects, a log and a ball. Each cat was observed during five days in each condition. Results show an important novelty effect at the beginning of observations, especially for rubbing and paddling behaviour. Introduction of objects in the cages resulted in a decrease in inactivity and self-play activities, and an increase in sniffing objects and play behaviours with objects. This was particularly important with the ball. Whereas these modifications decreased over days with the log, a high level of activity was maintained with the ball. The importance of the movement and of the function of the object is discussed. An improved way of rearing isolated cats is suggested.

Efforts to promote the psychological well-being of captive non-human primates through the application of environmental enrichment techniques are becoming more common. However, from this perspective relatively little empirical work has been done on the effects of manipulation of the social environment. The data currently available indicate that primates kept in solitary confinement are likely to develop a variety of behavioural and physiological disturbances reflecting reduced well-being, whereas most compatibly socially housed primates appear better adapted. There is always some risk associated with manipulating the social environment for experimental or husbandry reasons, but the risk of deleterious consequences can be reduced by a good knowledge of the animals’ normal repertoire and careful monitoring of how the animals adjust to the new conditions. Attending to the social environment of captive primates is fundamental to their welfare.

Eight baboon groups (Papio sp.) were observed for over one hundred scan samples both before and after the provision of structural enrichment. Additions to their home-cage included a galvanized ladder suspended horizontally by chains and a plastic drum hung from the ladder. Observations were conducted for three weeks before and three weeks after the structures were added to determine changes in space use. The baboons ‘ age-sex class and location were recorded at 10 minute intervals over a 60 minute time period. Groups were categorized as small, medium or large for analysis. The baboons spent most of their time on the floor and the bench and this pattern did not change with the addition of the new structures. The female baboons used the new structures an average of 16.5 per cent of the observation time, the males used them 13.6 per cent of the time, and the infants used them 10.1 per cent of the time. Of the new structures, males, females and infants all used the ladder the most. Females and infants used areas that were inaccessible to males and no group size differences were found.

We discuss the properties of controllability and complexity in novel object enrichment, their definition and present a critique of previous work related to them. We address the relationship between control and complexity, the evolutionary basis of their attractiveness and suggest that the acquisition of control may be a more enriching process than its execution. We propose that, although little work has been directed at separating their relative contributions to enrichment, controllability appears more important than complexity. We discuss the ways in which objects can be responsive both in terms of the predictability of the response and the ‘grade’ of actor-object interaction.

Foxes have been kept in captivity in Europe for the purpose of fur production for 70-80 years. In comparison with the main domesticated animal species, this is a very recent intervention. This paper reviews available evidence concerning the welfare of farmed foxes in relation to housing and management. The bulk of the literature relates to early handling of cubs, with the intention of reducing their subsequent fear of humans, and to simple changes in the cage environment that may provide environmental enrichment for foxes. Fear of humans appears to be a significant and pervasive problem, and the barrenness of cages is also a cause for concern. The extent of abnormal behaviours and reproductive failure, both indicative of quite severe welfare problems, is not sufficiently documented. Some housing and management practices are less detrimental than others; nonetheless, the evidence suggests that the welfare of farmed foxes is poor.
