Cooperation, essential for human success, is often reinforced through rituals that strengthen social bonds and collective identity. We hypothesized that mourning rituals enhance prosocial behaviour, and that this relationship is mediated by subjective well-being. To test these hypotheses, study 1 utilized quantitative surveys to assess the pathway between ritual participation, well-being and prosociality. In support of our hypotheses, we found a strong total effect of ritual participation on prosociality, and strong evidence for the pathway between ritual participation, well-being and prosociality. To contextualize these findings, study 2 employed qualitative methods, including focus groups and interviews, to capture participants' experiences. Narratives illustrated how mourning rituals facilitated communication, emotional expression and community cohesion. Participants noted that rituals helped process grief and reinforced social ties. However, some rituals were perceived negatively, highlighting their complex emotional impact. Overall, our findings suggest that Luhya mourning rituals are vital for enhancing well-being and fostering prosociality, emphasizing the importance of cultural practices in promoting cooperation across communities.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Such developmental variability (or bias) is common and uncontroversial. However, how and at what time scales these biases constrain or facilitate the emergence of standing genetic variation, plastic responses, as well as adaptation remains contentious. To investigate the extent to which developmental variability shapes genetic variation, plasticity and evolution, we first quantify developmental variability in the shape of the dung beetle foreleg-a functional trait critical for the excavation of breeding tunnels. We do so by testing how random developmental perturbations, manifesting themselves in fluctuating asymmetry, shape standing genetic variation within populations. Next, we investigate whether such developmental variability is aligned with thermal plasticity and recently evolved latitudinal variation. We find that, while developmental variability is a strong predictor of standing genetic (co)variance (i.e. the G-matrix), latitudinal population differentiation and thermal plasticity were unrelated to developmental variability. This suggests that, while developmental variability may shape standing genetic variation, it does not seem to constrain the evolution of putatively adaptive population differentiation and plastic responses. At least in this system, developmental biases do not seem to constrain morphological differentiation on ecological time scales.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Increasingly intense droughts across the globe have profound implications for the transmission of these diseases, as drought conditions can alter mosquito breeding habitats, host-seeking behaviours and mosquito-host contact rates. To quantify the effect of drought on disease transmission, we use West Nile virus as a model system and leverage a robust mosquito and virus dataset consisting of over 500 000 trap nights collected from 2010 to 2023, spanning a historic drought period followed by atmospheric rivers. We pair this surveillance dataset with a novel modelling approach that incorporates monthly changes in bird host community competence, along with drought conditions, to estimate the effect of drought severity on West Nile virus risk using panel regression models. Our results show that while drought decreases mosquito abundances, it paradoxically increases West Nile virus infection rates. This counterintuitive pattern probably stems from reduced water availability, which concentrates mosquitoes and pathogen-amplifying bird hosts around limited water sources, thereby increasing disease transmission risk. However, the magnitude of the effect depends critically on mosquito species, suggesting species-specific behavioural traits are key to understanding the effect of drought on mosquito-borne disease risk across real landscapes.","PeriodicalId":520757,"journal":{"name":"Proceedings.

We combined experimental and modelling work to examine the impact of crowding of butterfly larvae on the per-capita risk of infection by a protozoan that is transmitted via the larval food plant, and the resulting infection load in adult butterflies. We reared larvae at different densities and exposed them to low and high doses of parasites. We modified an existing model to include effects of conspecific density on food (and thus parasite) consumption rate and infected adult mortality rate. Experimental work indicated that the proportion of infected hosts on plants with ten caterpillars were reduced by at least 50% compared with single caterpillars. High density reduced per-capita infection risk and parasite load and extended lifespan of all hosts, as crowded hosts removed parasites from the environment. Modelling suggested that the lower consumption rate due to crowding can lower infection prevalence by as much as 20%, although the number of new cases increases with larger population size. Our results highlight that the expected positive relationship between host density and infection prevalence breaks down when crowding results in removal of infectious propagules from the environment.","PeriodicalId":520757,"journal":{"name":"Proceedings.

While the toxic effects of metals on bees are well documented, their ability to avoid contaminated food sources, and whether this behaviour is shaped by social context, remains unclear. Using the buff-tailed bumble bee and two metals, copper (i.e. essential metal) and cadmium (i.e. non-essential metal), we first assessed workers' avoidance of metal-laced 50% sucrose solutions when given the choice of an uncontaminated alternative. We introduced an energetic trade-off situation by reducing sucrose concentration to 20% in the untreated solution. Finally, to test the influence of brood care, workers were kept either with or without larval siblings. When both treated and untreated solutions contained 50% sucrose, workers consistently avoided the metal-contaminated solution, regardless of brood presence. However, when sucrose concentration was reduced in the uncontaminated solution, workers preferred the contaminated option, but only in the absence of brood. In the presence of brood, workers favoured the metal-free but sucrose-poor solution, suggesting adaptive provisioning behaviour to protect larvae. This study provides the first evidence that bumble bee workers not only actively avoid metal-contaminated solutions but also adjust foraging strategies based on social context.","PeriodicalId":520757,"journal":{"name":"Proceedings.

Moreover, the role of environmental variables shaping latitudinal gradients of predation intensity has seldom been tested. Here, we quantify predation by shell-breaking crabs on modern shells of the marine gastropod Trophon geversianus along a latitudinal gradient (40°-54° S) on the southwestern Atlantic coast. We further evaluate how intrinsic factors (four shell morphometric traits) and extrinsic factors (seven environmental variables and the biogeographic region) jointly influence predation patterns. Fragmentation from crushing predation affected 37% of the shells (544 out of 1480), with the most frequent damage types being major body whorl damage (28%), deep aperture chips (11%) and extensive aperture chips (6%). When analysed by biogeographic province, fragmentation increased significantly towards the south in the Magellan province. Notably, random forest modelling revealed that intrinsic factors-particularly shell size and thickness-were stronger predictors than extrinsic factors in driving latitudinal variability of shell-breaking crab predation. By highlighting the dominant influence of intrinsic factors over extrinsic ones, this study emphasizes the crucial role of species-specific traits in shaping predator-prey interactions across biogeographic regions.","PeriodicalId":520757,"journal":{"name":"Proceedings.

This commentary situates these results within a neurodevelopmental and evolutionary framework, proposing that social curiosity is a manifestation of a deeply conserved, motivationally driven system for social valuation centred on the medial prefrontal cortex (mPFC). We synthesize neuroimaging evidence showing selective engagement of mPFC while infants attend to third-party social interactions. We propose that the mPFC, as a primary valuation hub, guides the specialization of social perceptual regions over development. This framework interprets social curiosity as a high-level cognitive function driven by the mPFC, assigning intrinsic reward value to social information, consistent with the social information hypothesis. The willingness of older children to preferentially orient to and forgo a reward for social information can thus be understood as the behavioural output of a brain system calibrated from infancy to tag such information as intrinsically valuable.","PeriodicalId":520757,"journal":{"name":"Proceedings.

We hypothesized that animals prioritize maintaining beneficial social ties during fission. We assessed post-fission group choice in philopatric adult female blue monkeys by considering the strength and consistency of their social ties, dominance relations and relatedness with female peers, as well as their risk of infanticide and ties to the original group's resident male. Using a temporal network model, we assessed which females remained together (i.e. maintained ties) after fission. Females preferentially maintained ties to individuals with whom they had consistently strong affiliative ties before fission. More closely related individuals were likely to maintain ties only if they had similar risks of infanticide. Conditional logit models showed that females vulnerable to infanticide were more likely to join the post-fission group with the original group's resident male than the group without him. Overall, female blue monkeys appear to consider multiple types of relationships when structuring their post-fission groups, prioritizing consistent affiliative ties with other females and ties with a familiar male, and even separating from kin when infant offspring are vulnerable. The relationships prioritized during fission likely confer benefits, and females' choices illuminate how sociality influences decision-making.","PeriodicalId":520757,"journal":{"name":"Proceedings.
