Globally, non-human primates face mounting threats due to unsustainable harvest by humans. There is a need to better understand the diverse drivers of primate harvest and the complex social-ecological interactions influencing harvest in shared human-primate systems. Here, we take an interdisciplinary, systems approach to assess how complex interactions among primate biological and ecological characteristics and human social factors affect primate harvest. We apply our approach through a review and synthesis of the literature on lemur harvest in Madagascar, a country with one of the highest primate species richness in the world coupled with high rates of threatened primate species and populations in decline. We identify social and ecological factors affecting primate harvest, including the characteristics of lemurs that may make them vulnerable to harvest by humans; factors describing human motivations for (or deterrents to) harvest; and political and governance factors related to power and accessibility. We then discuss social-ecological interactions that emerge from: (1) the prevalence of informal institutions (e.g., cultural taboos), (2) adoption of human predatory strategies, (3) synergies with habitat use and habitat loss, and (4) interactions among regional- and local-scale factors (multi-level interactions). Our results illustrate that social-ecological interactions influencing lemur harvest in Madagascar are complex and context-specific, while influenced by a combination of interactions between species-specific characteristics and human social factors. These context-specific interactions may be also influenced by local-level cultural practices, land use change, and effects from regional-level social complexities such as political upheaval and food insecurity. We conclude by discussing the importance of identifying and explicitly accounting for nuances in underlying social-ecological systems and putting forth ideas for future research on primate harvest in shared human-primate systems, including research on social-ecological feedbacks and the application of Routine Activities Theory.

Background: Loneliness is a growing public health concern, yet little is known about loneliness in young people. The current study aimed to identify social ecological factors related to loneliness and examine the extent to which geographic region accounts for differences in loneliness.Methods: The data come from a cross-sectional sample of 6503 young people living in the United Kingdom. Loneliness was measured using the UCLA 3-item scale. Bivariate analyses were used to test associations between each predictor and loneliness. Multilevel models were used to identify key social ecological factors related to loneliness, and the extent to which loneliness varied across geographic regions. Results: Socio-demographic, social, health and wellbeing, and community factors were found to be associated with loneliness. Geographic region accounted for 5-8% of the variation in loneliness. The effect of gender, sexual orientation, and minority ethnic background on loneliness differed across geographic regions. Conclusions: This is the first study to highlight modifiable social and community factors related to youth loneliness, and individual vulnerabilities, such as poor mental wellbeing. Results related to geographic differences suggest that local-level initiatives may be most appropriate in tackling loneliness, rather than wider, less contextualized national efforts.

International interest in increasing marine protected area (MPA) coverage reflects broad recognition of the MPA as a key tool for marine ecosystems and fisheries management. Nevertheless, effective management remains a significant challenge. The present study contributes to enriching an understanding of best practices for MPA management through analysis of archived community survey data collected in the Philippines by the Learning Project (LP), a collaboration with United States Coral Triangle Initiative (USCTI), United States Agency for International Development (USAID), and partners. We evaluate stakeholder participation and social ecological interactions among resource users in MPA programs in the Palawan, Occidental Mindoro, and Batangas provinces in the Philippines. Analysis indicates that a complex suite of social ecological factors including demographics, conservation beliefs, scientifically correct knowledge, perceptions of personal benefit, and perceptions of fish scarcity influence participation, which in turn is related to perceived MPA performance. Findings indicate positive feedbacks within the system that have potential to strengthen perceptions of MPA success. The results of this evaluation provide empirical reinforcement to current inquiries concerning the role of participation in influencing MPA performance.

NOTE: THIS ARTICLE WAS PUBLISHED WITH THE INFORMING SCIENCE INSTITUTE. Aim/Purpose................................................................................................................................................................................................. Study aimed to examine the impacts of the Bui-Dam Hydroelectric Power (BHP) project resettlement on communities’ livelihoods. The purpose was to understand how the resettlement affected livelihood assets, activities, and capabilities of communities and households. Background................................................................................................................................................................................................. Induced displacements and livelihoods of households and communities have received enormous scholarly attention in many academic disciplines. In this paper, we add to the contributions in this issue area, employing a case study, to examine the livelihood effects to communities involved in the Phase A of the Bui Resettlement Program in Jama, Ghana. Methodology................................................................................................................................................................................................. In-depth interviews, focus group discussions, and observations were used to closely understand, from the perspective of stakeholders, including affected households, community leaders, and resettlement authorities, the impact of the project on livelihood capabilities, assets and activities. Contribution................................................................................................................................................................................................. The study has shown that resettlement presents communities with both challenges and opportunities. This conclusion is important in planning future projects, because, it will allow practitioners to carefully plan with both dimensions at sight. Findings ....................................................................................................................................................................................................... The study revealed that livelihood assets, including agricultural lands and fishing lake, were affected. However, farmlands were replaced while the lake remained accessible to households, posing little change in general livelihood activities. The quality and adequacy of the new resources were however in question, and some households were forced to change activities. Capabilities of resettled people were not affected; however, some were rendered useless in the new location while social ties and sense of belongingness were negatively affected. Recommendations for Practitioners........................................................................................................................................................... Considering the findings of this research, for future induced resettlement, we recommend that proactive measure be taken to understand the potential impacts of projects to be incorporated into planning. In addition, livelihood supports should be planned on long-term basis, to ensure that all potential impacts are predetermined. Broadly, context-specific safeguard policies should be pursued at the local level. Recommendation for Researchers............................................................................................................................................................ It is important to consider both the positive and negative impacts of induced resettlement to provide a holistic picture of how it affects households and communities. Researchers studying resettlement must therefore expand their scope of consideration to inform holistic policy actions. Impact on Society........................................................................................................................................................................................ The study provides findings that can enhance the sustainability of community livelihoods in the face of infrastructural development activities in pursuit of economic growth. Future Research........................................................................................................................................................................................... From the research perspective, future studies could well focus on understanding both dimensions of the impacts of various projects. Such an approach will provide valuable inputs to development planners and practitioners on how to effectively optimize project outcomes. The findings will also serve as a benchmark for people studying the same project long after all the phases are completed.

To support school physical education, United States (US) national organizations in medicine, health, and education recommend that schools adopt comprehensive school physical activity programmes (CSPAPs). An important factor in successful CSPAP implementation is the involvement of the school principal. The purpose of this study was to examine relationships between principals’ self-reported CSPAP involvement and their social-ecological-based perceptions about CSPAPs. We analysed survey responses from a national sample of principals in the US who indicated their school had a CSPAP ( n = 198). Exploratory structural equation modelling supported a single-factor solution for CSPAP involvement (12 items) and three social-ecological factors, which we labelled ‘intrapersonal’ (nine items mainly focused on expected outcomes of CSPAPs), ‘interpersonal’ (five items focused on parents’ and teachers’ support of the CSPAP), and ‘environmental’ (12 items focused on the support of the overall school environment, the community surrounding the school, and public policy for the CSPAP). Path analysis showed involvement factor scores are predicted by intrapersonal factor scores, which, in turn, are predicted by interpersonal and environmental factor scores. The results of this study are helpful in identifying targets for future research and practice related to CSPAP implementation and can inform efforts to prepare and support principals with respect to their CSPAP involvement.

Many organisms participate in symbiotic relationships with other organisms, yet studies of symbioses typically have focused on the reciprocal costs and benefits within a particular host-symbiont pair. Recent studies indicate that many ecological interactions involve alliances of symbionts acting together as mutualistic consortia against other consortia. Such interacting consortia are likely to be widespread in nature, even if the interactions often occur in a cryptic fashion. Little theory and empirical data exist concerning how these complex interactions shape ecological outcomes in nature. Here, we review recent work on fungal-fungal interactions between two consortia: (i) leaf-cutting ants and their symbiotic fungi (the latter grown as a food crop by the former) and (ii) tropical plants and their foliar endophytes (the cryptic symbiotic fungi within leaves of the former). Plant characteristics (e.g., secondary compounds or leaf physical properties of leaves) are involved in leaf-cutting ant preferences, and a synthesis of published information suggests that these plant traits could be modified by fungal presence. We discuss potential mechanisms for how fungal-fungal interactions proceed in the leaf-cutting ant agriculture and suggest themes for future research.
