Abstract
During COVID-19, there has been a surge in public interest for information on immunity-boosting foods. There is little scientific support for immunity-supporting properties of specific foods, but strong evidence for food choice impacts on other health outcomes (e.g. risk of non-communicable disease) and environmental sustainability. Here, we relate online recommendations for "immunity-boosting" foods across five continents to their environmental and human health impacts. More frequently recommended food items and groups are plant based and have lower land use and greenhouse gas emission impacts plus more positive health outcomes (reducing relative risks of mortality or chronic diet-related diseases) per serving of food. We identify trade-offs between environmental outcomes of increasing consumption of recommended food items, with aquatic environment impacts increasing with food recommendation frequency. People's reliance on the Internet for health information creates an opportunity to consolidate behaviour change towards consuming foods with multiple co-benefits. Our study identifies win-win options for nudging online information-seeking behaviour towards more sustainable choices for terrestrial biodiversity conservation and human health.

J Adv Res 2022; 36:187-199. [PMID: 35127173 PMCID: PMC8799911 DOI: 10.1016/j.jare.2021.07.005] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/24/2020] [Revised: 06/23/2021] [Accepted: 07/08/2021] [Indexed: 11/18/2022] Open
Abstract
A growth‒defense tradeoff following root pruning. Root growth lagged behind root physiology after root pruning. The growth–defense tradeoff was induced by indole-3-acetic acid. Proteomic analysis supported a growth–defense tradeoff. Root pruning altered the expression of genes at the protein and mRNA levels.
Introduction Root pruning is commonly used to facilitate seedling transplantation for the restoration of degraded or damaged ecosystems. However, little is known about how root growth coordinates morphology, physiology and defense functions following root pruning. Objectives We aim to elucidate whether and how root growth trades off with defense functioning after pruning. Methods Seedlings of Platycladus orientalis, a tree species widely used in forest restoration, were subjected to root pruning treatment. A suite of root growth, morphological and physiological traits were measured after pruning in combination with proteomic analysis. Results Root growth was insensitive to pruning until at 504 h with a significant increase of 16.8%, whereas root physiology was activated rapidly after pruning. Key root morphological traits, such as root diameter, specific root length and root tissue density, showed no response to the pruning treatment. Plant defense syndromes such as reactive oxygen species-scavenging enzymes and defensive phytohormones such as jasmonic acid and abscisic acid, were recruited at six hours after pruning and recovered to the unpruned levels at 504 h. Compared with the controls, 271, 360 and 106 proteins were differentially expressed at 6, 72 and 504 h after root pruning, respectively. These proteins, associated with defense function, showed temporal patterns similar to the above defense syndromes. Conclusion Our results suggest a root growth-defense tradeoff following root pruning in P. orientalis. This tradeoff was potentially due to the significant increase of indole-3-acetic acid, the phytohormone stimulating root branching, which occurred soon after pruning. Together, these results provide a holistic understanding of how root growth is coordinated with root morphology, physiology, and defense in response to root pruning.

Abstract
Earth faces a climate emergency which renders conservation goals largely obsolete. Current conservation actions are inadequate because they (i) underplay biodiversity's role in maintaining human civilisation, which contributes to its marginalisation, and (ii) rely on false assumptions of how to catalyse transformative change. We suggest a paradigm shift from biodiversity conservation to survival ecology, refocusing the field on safeguarding a planetary system in which humans and other species can thrive. Rather than seeking to maintain a world which will no longer exist, survival ecology acknowledges unavoidable change and seeks to shape the world that will: it looks to the future, not the past. Since conservation science and advocacy have not been sufficient to achieve the required change, survival ecologists should additionally embrace non-violent civil disobedience.

Abstract
Twenty years ago, we published an assessment of the threats facing primates and with the passing of two decades, we re-evaluate identified threats, consider emerging pressures, identify exciting new avenues of research, and tackle how to change the system to rapidly advance primate and primate habitat conservation. Habitat destruction and hunting have increased, the danger of looming climate change is clearer, and there are emerging threats such as the sublethal effects of microplastics and pesticides. Despite these negative developments, protected areas are increasing, exciting new tools are now available, and the number of studies has grown exponentially. Many of the changes that need to occur to make rapid progress in primate conservation are in our purview to modify. We identify several dimensions indicating the time is right to make large advances; however, the question that remains is do we have the will to prevent widespread primate annihilation and extinction?

Abstract
Accelerating declines in biodiversity and unmet targets in the Convention on Biological Diversity's 2010-2020 Strategic Plan for Biodiversity are stimulating widespread calls for transformative change. Such change includes societal transitions toward sustainability, as well as in specific content of the CBD's draft Post-2020 Global Biodiversity Framework. We summarize research on transformative change and its links to biodiversity conservation, and discuss how it may influence the work of the CBD. We identify five steps to inject transformative change into the design and implementation of a new post-2020 framework: Pay attention to lessons learned from transitions research, plan for climate change, reframe area-based conservation, scale up biodiversity mainstreaming, and increase resources. These actions will transform the very nature of work under the CBD; a convention based on voluntary implementation by countries and facilitated by international administrators and experts must now accommodate a broader range of participants including businesses, Indigenous peoples, and multiple nonstate actors.

Abstract
Wind energy is the leading renewable technology towards achieving climate goals, yet biodiversity trade-offs via land take are emerging. Thus, we are facing the paradox of impacting on biodiversity to combat climate change. We suggest a novel method of spatial planning that enhances windfarm sustainability: investments are prioritized in the most fragmented zones that lie outside the Natura 2000 network of protected areas. We showcase it in Greece, a biodiversity hotspot with a strong climate policy and land conflict between conservation and wind energy schemes. The analysis indicates that the suggested investment zone supports wind harnessing 1.5 times higher than the 2030 national goal, having only marginally lower (4%) wind speed. It performs well for the conservation of the annexed habitats and species of the two Nature Directives and it greatly overlaps with the Important Bird Areas (93%) and the roadless areas (80%) of Greece. It also greatly overlaps (82%-91%) with the exclusion zones suggested according to three sensitivity maps for bird conservation. Since land use change triggers biodiversity decline, we underline the necessity of such approaches for meeting both climate and biodiversity goals and call for a greater environmental policy convergence towards biodiversity conservation and no net land take.

Abstract
Wildlife is declining around the world. Many developed nations have enacted legislation on endangered species protection and provide funding for wildlife recovery. Protecting endangered species is also supported by the public and judiciary. Yet, despite what appear as enabling conditions, wild species continue to decline. Our paper explores pathways to endangered species recovery by analyzing the barriers that have been identified in Canada, the United States, and Australia. We summarize these findings based on Canada’s Species at Risk Conservation Cycle (assessment, protection, recovery planning, implementation, and monitoring and evaluation) and then identify 10 “bridges” that could help overcome these barriers and bend our current trajectory of wildlife loss to recovery. These bridges include ecosystem approaches to recovery, building capacity for community co-governance, linking wildlife recovery to ecosystem services, and improving our storytelling about the loss and recovery of wildlife. The focus of our conclusions is the Canadian setting, but our findings can be applied in other national and subnational settings to reverse the decline of wildlife and halt extinction.

Abstract
Biodiversity loss and climate change are often considered as intertwined issues. However, they do not receive equal attention. Even in the context of nature-based climate solutions, which consider ecosystems to be crucial to mitigate and adapt to the impacts of climate change, the potential role of biodiversity has received little attention. Here this essay emphasizes biodiversity as the cause-not only the consequence-to help society and nature face challenges associated with the changing climate. Reconsidering and emphasizing the linkages between these twin environmental crises is urgently needed to make collective efforts for the environment truly effective.

Abstract
The conservation of biodiversity-and the vital ecosystem services it generates-is one of the greatest challenges humanity faces, yet the field faces drastic funding cuts as society realigns its priorities in the face of the COVID-19 pandemic. Here, we argue that diverting attention from conservation would, however, increase the risk of further global health crises because the emergence of novel infectious diseases is partially driven by global environmental change. As the discrepancy between conservation needs and society's willingness to pay for them grows, conservation will have to evolve to stay relevant in the age global change-induced human infectious disease.
