Exploring the human-nature nexus towards effective nature-based solutions: the Aral Sea case
Incorporating societal challenges and values into the design of locally appropriate nature-based solutions (NbS) is an integral strategy for ensuring benefits for both communities and the environment. But how are human-nature relations impacted when the environments containing resources which are valued and relied on, undergo dramatic and sustained change on decadal timescales? To explore this interplay, we selected Muynak as a case study, once a thriving town on the shores of the former Aral Sea in Uzbekistan. We conducted a social survey among the residents to identify the use of natural resources and the values they assign to the most common and yet highly degraded resources in the area (wetlands, rangelands, afforested areas, the Aral Sea, and wildlife). The survey was complemented with expert interviews. Our study suggests that grasslands are the most frequently used of the resources under study, while wetlands and wildlife are generally more valued. Overall, resources were more culturally valued than financially, historically, or recreationally. The majority of respondents perceived a degradation in most natural resources over the past decade, particularly wetlands (79 %), followed by grasslands (48 %), and the Aral Sea (42 %). Wetlands were reported to be in a state of ongoing degradation by 79 % of respondents, which negatively affected the livelihoods of almost half of the households in the survey area. Afforested areas were the only resources reported to have a positive perceived change in both status and their effect on well-being. The vast majority of respondents (83 %) felt that human well-being was linked to environmental conditions. This study lays the foundation for future interventions to develop nature-based solutions to benefit both people and nature, and highlights the continuing value placed on nature by residents of an area that has suffered substantial anthropogenic degradation
A framework for understanding the contributions of local residents to protected area law enforcement
Terrestrial and marine protected areas have long been championed as an approach to biodiversity conservation. For protected areas to be effective, equitable and inclusive, the involvement of local residents in their management and governance is considered important. Globally, there are many approaches to involving local residents in protected area law enforcement. However, opportunities for comparing different approaches have been limited by the lack of a clear common framework for analysis. To support a more holistic understanding, we present a framework for analysing the contributions of local residents to protected area law enforcement. Informed by a review of the literature and discussions with conservation practitioners, the framework comprises five key dimensions: (1) the different points in the enforcement system at which local residents are involved, (2) the nature of local participation in decision-making, (3) the type of external support provided to local residents, (4) the different motivating forces for participation, and (5) the extent to which local participation is formalized. We apply the framework to three real-world case studies to demonstrate its use in analysing and comparing the characteristics of different approaches. We suggest this framework could be used to examine variation in local participation within the enforcement system, inform evaluation and frame constructive discussions between relevant stakeholders. With the global coverage of protected areas likely to increase, the framework provides a foundation for better understanding the contributions of local residents to protected area law enforcement

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
Aquatic Mammals
Abstract Twenty neonatal harbor seal (Phoca vitulina) pups in rehabilitation following maternal separation underwent serial echocardiographic studies to assess patency and subsequent age of functional closure of the ductus arteriosus (d.a.). B-mode, color-flow Doppler, and pulse and continuous wave Doppler were utilized to identify the d.a. and determine patency and directionality of blood flow. Seals were also evaluated for evidence of foramen ovale (f.o.) patency. B-mode ultrasound was used to evaluate the inter-atrial septum for abnormal (aneurismal) motion, a sign of f.o. patency in other species. In one harbor seal, this motion was confirmed as being consistent with f.o. patency by contrast echocardiography. Closure of the f.o. was not confirmed in any harbor seal prior to release back into the free-ranging population. Data acquired indicate that there is patency of the f.o. and d.a. after birth for a longer period in phocids than in described terrestrial mammals
Net positive outcomes for nature
Much research and policy effort is being expended on seeking ways to conserve living nature while enabling the economic and social development needed to increase global equity and end poverty. We propose that this will only be possible if the language of policy shifts away from setting conservation targets that focus on avoiding losses and towards developing processes that consider net outcomes for biodiversity

Translating the terrestrial mitigation hierarchy to marine megafauna bycatch
In terrestrial and coastal systems, the mitigation hierarchy is widely and
increasingly used to guide actions to ensure that no net loss of biodiversity
ensues from development. We develop a conceptual model which applies
this approach to the mitigation of marine megafauna bycatch in fisheries,
going from defining an overarching goal with an associated quantitative
target, through avoidance, minimisation, remediation to offsetting. We
demonstrate the framework's utility as a tool for structuring thinking and
exposing uncertainties. We draw comparisons between debates ongoing in
terrestrial situations and in bycatch mitigation, to show how insights from
each could inform the other; these are the hierarchical nature of
mitigation, out-of-kind offsets, research as an offset, incentivising
implementation of mitigation measures, societal limits and uncertainty. We
explore how economic incentives could be used throughout the hierarchy to improve the achievement of bycatch goals. We conclude by highlighting the
importance of clear agreed goals, of thinking beyond single species and
individual jurisdictions to account for complex interactions and policy
leakage, of taking uncertainty explicitly into account, and of thinking
creatively about approaches to bycatch mitigation in order to improve
outcomes for conservation and fishers. We suggest that the framework set
out here could be helpful in supporting efforts to improve by catch
mitigation efforts, and highlight the need for a full empirical application to
substantiate this
