Combining simulation and empirical data to explore the scope for social network interventions in conservation
Conservationists can use social network analysis to improve targeting for behaviour-change interventions, selecting individuals to target who will go on to inform or influence others. However, collecting sociometric data is expensive. Using empirical data from a case study in Cambodia and simulations we examine the conditions under which collecting this data is cost-effective. Our results show that targeting interventions using sociometric data can lead to greater dissemination of information and adoption of new behaviours. However, these approaches are not cost-effective for small interventions implemented in only a few communities, and it is an order of magnitude cheaper to achieve the same results by simply targeting more individuals in each community at random. For interventions across multiple communities, network data from one community could inform rules-of-thumb that can be applied to boost the effectiveness of interventions. In rural Cambodia, this approach is worthwhile if it can inform interventions covering at least 21 villages. Our findings provide a framework for understanding how insights from network sciences, such as targeting clusters of individuals for interventions that aim to change behaviour, can make a practical contribution to conservation
Improving environmental interventions by understanding information flows
Conservationists are increasingly interested in changing human behaviour. One understudied aspect of such interventions is information flow. Different patterns of interpersonal communication and social structures within communities influence the adoption of behavioural changes through social influence and social reinforcement. Understanding the structure of information flow in a group, using tools such as social network analysis, can therefore offer important insights for interventions. For example, communications may be targeted to highly connected opinion leaders to leverage their influence, or communication may be facilitated between distinct subgroups to promote peer learning. Incorporating these approaches into conservation interventions can promote more effective behaviour change. This review introduces conservation researchers and practitioners to key concepts underpinning information flows for interventions targeting networks of individuals
Balancing making a difference with making a living in the conservation sector
Goals play important roles in people's lives by focusing attention, mobilizing effort, and sustaining motivation. Understanding conservationistsâ satisfaction with goal progress may provide insights into real-world environmental trends and flag risks to their well-being and motivation. We asked 2694 conservationists working globally how satisfied they were with progress towards goals important to them. We then explored how this satisfaction varied between groups. Finally, we looked at respondents' experiences associated with goal progress satisfaction. Many (94.0%) said âmaking a meaningful contribution to conservationâ was an important goal for them, with over half being satisfied or very satisfied in this area (52.5%). However, respondents were generally dissatisfied with progress to collective conservation goals, such as stopping species loss, echoing formal assessments. Some groups were more likely to report dissatisfaction than others. For instance, those in conservation for longer tended to be less satisfied with collective goal progress (log-odds -0.21, 95% credibility interval (CI) -0.32 to -0.10), but practitioners reported greater satisfaction (log-odds 0.38, 95% CI 0.15-0.60). Likewise, those who are more optimistic in life (log-odds 0.24, 95% CI 0.17-0.32), male (log-odds 0.25, 95% CI 0.10-0.41), and working in conservation practice (log-odds 0.25, 95% CI 0.08-0.43) reported greater satisfaction with individual goal progress. Free-text responses suggested widespread dissatisfaction around livelihood goals, particularly related to job security and adequate compensation. While contributing to conservation appeared to be a source of satisfaction, slow goal progress in other areas â particularly around making a living â looked to be a source of distress and demotivation. Employers, funders, professional societies, and others should consider ways to help those in the sector make a difference whilst making a living, including by prioritizing conservationists' well-being when allocating funding. This support could include avoiding exploitative practices, fostering supportive work environments, and celebrating positive outcomes
Personal traits predict conservationistsâ optimism about outcomes for nature
In the face of unprecedented biodiversity loss, the belief that conservation goals can be met could play an important role in ensuring they are fulfilled. We asked conservationists how optimistic they felt about key biodiversity outcomes over the next 10 years; 2341 people familiar with conservation in 144 countries responded. Respondents expressed optimism that enabling conditions for conservation would improve but felt pressures would continue, and the state of biodiversity was unlikely to get better. Respondents with greater general optimism about life, at early-career stages, and working in practice and policy (compared to academia) reported higher conservation optimism. But most of our biodiversity and conservation status indicators were not associated with conservation optimism. Unbounded optimism without appropriate action would be misguided in the face of growing threats to biodiversity. However, supporting those struggling to see the light at the end of the tunnel could help sustain efforts to overcome these threats
Ethical considerations when conservation research involves people
Social science is becoming increasingly important in conservation, with more studies involving methodologies that collect data from and about people. Conservation science is a normative and applied discipline designed to support and inform management and practice. Poor research practice risks harming participants, researchers, and can leave negative legacies. Often, those at the forefront of fieldâbased research are earlyâcareer researchers, many of whom enter their first research experience illâprepared for the ethical conundrums they may face. Here, we draw on our own experiences as earlyâcareer researchers to illuminate how ethical challenges arise during conservation research that involves human participants. Specifically, we discuss ethical review procedures, conflicts of values, and power relations, and provide broad recommendations on how to navigate ethical challenges when they arise during research. We encourage greater engagement with ethical review processes and highlight the pressing need to develop ethical guidelines for conservation research that involves human participants.Output Status: Forthcoming/Available Onlin
IL6 and CRP haplotypes are associated with COPD risk and systemic inflammation: a case-control study
<p>Abstract</p> <p>Background</p> <p>Elevated circulating levels of C-reactive protein (CRP), interleukin (IL)-6 and fibrinogen (FG) have been repeatedly associated with many adverse outcomes in patients with chronic obstructive pulmonary disease (COPD). To date, it remains unclear whether and to what extent systemic inflammation is primary or secondary in the pathogenesis of COPD.</p> <p>The aim of this study was to examine the association between haplotypes of <it>CRP</it>, <it>IL6 </it>and <it>FGB </it>genes, systemic inflammation, COPD risk and COPD-related phenotypes (respiratory impairment, exercise capacity and body composition).</p> <p>Methods</p> <p>Eighteen SNPs in three genes, representing optimal haplotype-tagging sets, were genotyped in 355 COPD patients and 195 healthy smokers. Plasma levels of CRP, IL-6 and FG were measured in the total study group. Differences in haplotype distributions were tested using the global and haplotype-specific statistics.</p> <p>Results</p> <p>Raised plasma levels of CRP, IL-6 and fibrinogen were demonstrated in COPD patients. However, COPD population was very heterogeneous: about 40% of patients had no evidence of systemic inflammation (CRP < 3 mg/uL or no inflammatory markers in their top quartile). Global test for haplotype effect indicated association of <it>CRP </it>gene and CRP plasma levels (P = 0.0004) and <it>IL6 </it>gene and COPD (P = 0.003). Subsequent analysis has shown that <it>IL6 </it>haplotype H2, associated with an increased COPD risk (p = 0.004, OR = 4.82; 1.64 to 4.18), was also associated with very low CRP levels (p = 0.0005). None of the genes were associated with COPD-related phenotypes.</p> <p>Conclusion</p> <p>Our findings suggest that common genetic variation in <it>CRP </it>and <it>IL6 </it>genes may contribute to heterogeneity of COPD population associated with systemic inflammation.</p

Using mixed methods to understand sensitive wildlife poisoning behaviours in northern Cambodia
In northern Cambodia, threatened wildlife, livestock and people are being poisoned by pesticides deposited in seasonal waterholes. Addressing this critical conservation threat requires understanding the drivers of poisoning behaviours and the social contexts in which they occur. This study across 10 communities in two protected areas aimed to provide a first assessment of this phenomenon. We used the theory of planned behaviour to measure socio-psychological determinants of behaviour and deepened this understanding using informant interviews and focus group discussions. Informants reported that so-called termite poisons, including powerful carbamates, are deliberately deposited at waterholes to catch wildlife for consumption. This method is perceived to be low effort and high efficacy, and perceptions of the health risks vary. Predominant users are young men and children, but it is unclear whether the practice is related to food insecurity. Threatened wildlife species reported as affected include the giant ibis Pseudibis gigantea and vulture species. Overall, social norms are strongly negative towards poisoning; 75% of survey respondents perceived negative norms because of impacts on human and livestock health, environmental quality, and risks of legal sanctions. This has led to interventions by local authorities in half of the studied villages. We suggest that future interventions should raise the salience of negative norms by providing a non-conflictual mechanism for community members to participate in monitoring and sanctioning, such as a reporting hotline. Regulatory interventions are also required to control the supply of restricted pesticides
