We produced the first systematic map on how commercial video games engage with biodiversity and conservation. This includes 380 papers, five languages, 450 unique games, empirical and non-empirical literature, as well as an interactive online database of the available evidence. Non-empirical work often scrutinises the extent that game design encourages or condemns exploitation of nature. Empirical papers are overwhelmingly non-experimental; research most often explores how video games represent real-world wildlife, influence players’ ecological perceptions, or inform players’ interactions with virtual nature. Despite the volume of literature, it is difficult to infer the causal effects of video games – especially on driving real-world pro-ecological action. Our map highlights several promising areas for future study, such as: consider the role of player differences on the impact of games, observe actual behaviours and how these change after play, and pursue interdisciplinary collaborations with the games industry for more thorough, applicable, and novel findings.

Video games could offer interactive and immersive environments for players to meaningfully engage with ecological topics. The literature base is expanding to offer more studies concerning links between commercial games and players’ ecological knowledge, relationships, and interactions. The primary objective of this systematic map is to provide an overview of the available literature regarding use of commercial video games to engage players with biodiversity conservation.

Workplaces can be sources of both stress and support, affecting employees' mental health and productivity. Yet, little research has investigated variability in workplace risk factors for poor mental health in conservation. We aimed to explore how patterns of psychological distress—a state of emotional disturbance—and associated workplace risk factors vary between conservation job roles. Working with three case study organizations in India, South Africa, and Cambodia, we surveyed 280 field‐based, office‐based, and research staff. Moderate or severe psychological distress was reported by 28.9%. Field‐based practitioners reported a greater imbalance between workplace efforts and rewards (0.35 standard deviation (SD), 95% credibility interval (CI) 0.03–0.67) than their colleagues, which was associated with greater psychological distress (0.24 SD, 95% CI 0.10–0.39). After controlling for this mediated relationship, researchers reported greater psychological distress than field‐based practitioners (0.37 SD, 95% CI 0.02–0.72). However, when accounting for all direct and indirect effects, there was no overall difference in distress between roles. Employers, funders, professional societies, and other institutions seeking to support conservationists' mental health should understand and offer support tailored to role‐specific challenges. Doing so might enhance conservationists' wellbeing while strengthening their ability to reverse global nature loss.

Biodiversity conservation work can be challenging but rewarding, and both aspects have potential consequences for conservationists' mental health. Yet, little is known about patterns of mental health among conservationists and its associated workplace protective and risk factors. A better understanding might help improve working conditions, supporting conservationists' job satisfaction, productivity, and engagement, while reducing costs from staff turnover, absenteeism, and presenteeism. We surveyed 2311 conservation professionals working in 122 countries through an internet survey shared via mailing lists, social media, and other channels. We asked them about experiences of psychological distress, working conditions, and personal characteristics. Over half were from and worked in Europe and North America, and most had a university-level education, were in desk-based academic and practitioner roles, and responded in English. Heavy workload, job demands, and organizational instability were linked to higher distress, but job stability and satisfaction with one's contributions to conservation were associated with lower distress. Respondents with low dispositional and conservation-specific optimism, poor physical health, and limited social support, women, and early-career professionals were most at risk of distress in our sample. Our results flag important risk factors that employers could consider, although further research is needed among groups underrepresented in our sample. Drawing on evidence-based occupational health interventions, we suggest measures that could promote better working conditions and thus may improve conservationists' mental health and abilities to protect nature.

Abstract 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.

Sea stars (class Asteroidea) can play powerful and wide-ranging roles as consumers of algae and other prey in benthic ecosystems worldwide. In the Gal ' apagos rocky subtidal zone, sea stars are abundant and diverse, but their distribution, feeding habits and ecological impacts have received little attention. We compared diets and distributions of the six most abundant sea star species to examine their functional roles. Bi-annual censuses carried out between 2006 and 2014 at two depths (6-8 m, 12-15 m) at 12 sites in Gal ' apagos identified two abundance "hotspots" and revealed higher densities at locations with more heterogeneous benthic topographies. Field surveys showed a high incidence of feeding (35-68% of individuals across species) and distinct diets were evident for each species in terms of food items and dietary breadth, suggesting niche partitioning. Most species can be classified as facultative herbivores, with diets dominated by crustose and turf algae supplemented by a small proportion of sessile invertebrates. The two most abundant species, Pentaceraster cumingi and Nidorellia armata, had the narrowest diets. Field prey selectivity experiments identified P. cumingi as a size-selective predator of small pencil urchins Eucidaris galapagensis. In field caging experiments, N. armata reduced biomass of unbleached crustose coralline algae by 72%. In the context of emerging threats such as disease, ocean acidification and climate change, a deeper understanding of the distinct functional roles of sea stars can inform ecological models and management plans.

A better understanding can help improve working conditions, supporting conservationists’ job satisfaction, productivity, and engagement, while reducing costs from staff turnover, absenteeism, and presenteeism. We surveyed 2311 conservationists across 143 countries, asking about experiences of psychological distress, personal characteristics, and workplace conditions. Moderate or severe distress was reported by 27.8%. Respondents with low dispositional and conservation-specific optimism, poor physical health, limited social support, women, and early-career professionals were most at risk. Heavy workload, job demands, and organisational instability were linked to higher distress, but job stability and satisfaction with one’s contributions to conservation were associated with lower distress. We suggest ways employers and others could support conservationists’ mental health and ability to tackle the global ecological crisis.

We suggest ways employers and others might ‘promote the positives’ and manage the risks of working in the sector, potentially supporting conservationists’ mental health and abilities to protect nature.

Background: Effective communication can play a vital role in societal transformations towards sustainability and biodiversity restoration. However, the complexity and long-term nature of environmental change presents a communication challenge. If not carefully navigated, messages around environmental degradation can lead to audience disengagement and issue fatigue, at a time when motivation, engagement and positive action is required. Methods: In this Conservation in Action piece, we describe the principles of positive communication, which are being adopted by a growing movement of conservation organizations. We support this approach by reviewing evidence on the role of emotions in decision-making from diverse fields such as psychology and communications, paying particularly close attention to the experiences of climate change communicators. Results: Positive emotional experiences, including feelings of hope, collective efficacy, and the warm glow that follows actions aligned with intrinsic values, can play an essential role in sustaining actions that contribute to transformative change. While negative emotions prime specific action tendencies, positive emotions enable creativity, cooperation, and resilience, which are all essential for overcoming the challenging nature of acting on the biodiversity crisis. Conclusions: Communications from conservation researchers and practitioners need to reflect the reality of the biodiversity crisis. While some communications may seek to motivate action through warnings and threats, messages that trigger positive emotions in audiences can help inspire long-term engagement and action. We suggest that this positive communication approach is underutilized. Implications: We present a guide to help those working in conservation convey their messages in ways that are empowering and positive. As the biodiversity crisis intensifies, it is critical that conservation professionals continue to imagine and develop pathways to a better future and communicate with others in society in a way that supports transformative change towards this future.

Conflicts between the interests of biodiversity conservation and other human activities pose a major threat to natural ecosystems and human well‐being, yet few methods exist to quantify their intensity and model their dynamics. We develop a categorization of conflict intensity based on the curve of conflict, a model originally used to track the escalation and deescalation of armed conflicts. Our categorization assigns six intensity levels reflecting the discourse and actions of stakeholders involved in a given conflict, from coexistence or collaboration to physical violence. Using a range of case studies, we demonstrate the value of our approach in quantifying conflict trends, estimating transition probabilities between conflict stages, and modeling conflict intensity as a function of relevant covariates. By taking an evidence‐based approach to quantifying stakeholder behavior, the proposed framework allows for a better understanding of the drivers of conservation conflict development across a diverse range of socioecological scenarios.

Sea stars (class Asteroidea) can play powerful and wide-ranging roles as consumers of algae and prey items in benthic ecosystems worldwide. In the Galápagos rocky subtidal zone, sea stars are abundant and diverse but their distribution, feeding habits and ecological impacts have received little attention. We compared diets and distributions across the six most abundant sea star species to examine functional roles of this important group. Bi-annual censuses carried out between 2006–2014 at two depths (6-8m, 12-15m) at 12 sites in Galápagos identified two abundance “hotspots” and revealed higher densities at locations with more heterogeneous benthic topographies. Field surveys revealed a high incidence of feeding (35–68% of individuals across species) and distinct diets were evident for each species in terms of food items and dietary breadth, suggesting niche partitioning. Most species can be classified as facultative herbivores, with diets dominated by crustose and turf algae supplemented by a small proportion of sessile invertebrates. The two most abundant species ( Pentaceraster cumingi and Nidorellia armata ) had the narrowest diets. Field prey selectivity experiments identified P. cumingi as a size-selective predator of the pencil urchin Eucidaris galapagensis . In field caging experiments, N. armata reduced biomass of unbleached crustose coralline algae and macroalgae by 72% and 52%, respectively. In the context of emerging threats such as disease, ocean acidification and climate change, a deeper understanding of distinct functional roles can inform ecological models and management plans.

Goals play important roles in people's lives because they focus attention, mobilize effort, and sustain motivation. Understanding conservationists' 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 toward goals important to them. We then explored how this satisfaction varied among groups, including demographic and occupational. Finally, we looked at respondents' experiences associated with goal-progress satisfaction. Many (94.0%) indicated that making a meaningful contribution to conservation was an important goal for them, and over half were satisfied or very satisfied in this area (52.5%). However, respondents were generally dissatisfied with progress on collective conservation goals (e.g., stopping species loss). 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 were 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 with livelihood goals, particularly related to job security and adequate compensation. Although contributing to conservation appeared to be a source of satisfaction, slow goal progress in other areas--particularly around making a living--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 while making a satisfactory living by, for example, prioritizing conservationists' well-being when allocating funding. This support could include avoiding exploitative practices, fostering supportive work environments, and celebrating positive outcomes.

Structures submerged in the sea by humans over millennia provide hard and longstanding evidence of anthropogenic influence in the marine environment. Many of these human-made reefs (HMRs) may provide opportunities for conservation despite having been created for different purposes such as fishing or tourism. In the middle of controversy around the costs and benefits of HMRs, a broad analysis of biodiversity and social values is necessary to assess conservation potential. This requires reframing HMRs as social-ecological systems, moving beyond comparisons with natural coral or rocky reefs to consider their roles as ecosystems in their own right; creating frameworks to track their type, number, size, units, location, characteristics, origins, social uses, and associated biodiversity locally and worldwide; and applying systematic assessment of conservation benefits in relation to stated conservation intentions. This integrative approach can catalyze learning, identify conservation opportunities, and inform positive management of HMRs into the future.
