In the face of the climate crisis, sustainability education must include a focus on understandings of socio-ecological systems (SES) and applying systems thinking (ST) skills. This study investigates a Community and Citizen Science (CCS) program designed for elementary school students to collect forest data to better understand their SES and gain insights into wildfire management in a California region recently ravaged by wildfires. We examine the development of fourth-grade students’ systems thinking skills and understandings of SES, seeing these as crucial components toward fostering agency with science to support climate resilience. We found that students were capable of recognizing the intricate impacts of wildfires on interconnected human and ecological systems and demonstrated varying levels of proficiency in systems thinking skills. This place-based CCS program cultivated knowledge and skills in young learners that may contribute to better socio-ecological resilience and proactive sustainability efforts.

Traditional harvest systems as models for advancing understanding of dynamics and resilience in socio‐ecological systems
Abstract Traditional harvest entails humans extracting and managing resources from intact, semi‐natural ecosystems. As such, it is inherently comprised of close interactions between humans and ecosystems and may provide unique insight into socio‐ecological systems. Traditional harvest is generally accompanied by traditional resource management and directly influences ecological community dynamics, species reproduction and distribution, and competitive interactions. Meanwhile, ecological processes, seasonality, and natural disturbances influence human behaviors, decision making, activities, and well‐being. As a result of this tight coupling, traditional harvest systems have the potential to serve as important laboratories for the study of ecological community dynamics. Resilience science, in particular, may benefit from greater appreciation of traditional harvest, wherein thresholds and bidirectional feedbacks may be more easily detected and modeled than in more diffuse socio‐ecological systems. Additionally, because traditional harvest links to cultural heritage and traditional ecological knowledge, a greater understanding of these systems may facilitate efforts to support marginalized communities and social equity. We here discuss the value of traditional harvest research for science and society, highlighting as a case study the traditional harvest of Emory oak acorns by Western Apache Tribal Nations. We argue that traditional harvest systems carry important heuristic value but are often assumed to be rare or declining and are therefore relatively neglected by researchers, yet their persistence in modern agriculture‐dominated systems exemplifies resilience. As environmental change persists and natural systems near critical tipping points, understanding the role of humans in ecosystem resilience will be necessary to develop effective and sustainable management.

Abstract Humans are dominant global drivers of ecological and evolutionary change, rearranging ecosystems and natural selection. In the present article, we show increasing evidence that human activity also plays a disproportionate role in shaping the eco-evolutionary potential of systems—the likelihood of ecological change generating evolutionary change and vice versa. We suggest that the net outcome of human influences on trait change, ecology, and the feedback loops that link them will often (but not always) be to increase eco-evolutionary potential, with important consequences for stability and resilience of populations, communities, and ecosystems. We also integrate existing ecological and evolutionary metrics to predict and manage the eco-evolutionary dynamics of human-affected systems. To support this framework, we use a simple eco–evo feedback model to show that factors affecting eco-evolutionary potential are major determinants of eco-evolutionary dynamics. Our framework suggests that proper management of anthropogenic effects requires a science of human effects on eco-evolutionary potential.more » « less

null (Ed.)Abstract Urbanization is changing Earth's ecosystems by altering the interactions and feedbacks between the fundamental ecological and evolutionary processes that maintain life. Humans in cities alter the eco-evolutionary play by simultaneously changing both the actors and the stage on which the eco-evolutionary play takes place. Urbanization modifies land surfaces, microclimates, habitat connectivity, ecological networks, food webs, species diversity, and species composition. These environmental changes can lead to changes in phenotypic, genetic, and cultural makeup of wild populations that have important consequences for ecosystem function and the essential services that nature provides to human society, such as nutrient cycling, pollination, seed dispersal, food production, and water and air purification. Understanding and monitoring urbanization-induced evolutionary changes is important to inform strategies to achieve sustainability. In the present article, we propose that understanding these dynamics requires rigorous characterization of urbanizing regions as rapidly evolving, tightly coupled human–natural systems. We explore how the emergent properties of urbanization affect eco-evolutionary dynamics across space and time. We identify five key urban drivers of change—habitat modification, connectivity, heterogeneity, novel disturbances, and biotic interactions—and highlight the direct consequences of urbanization-driven eco-evolutionary change for nature's contributions to people. Then, we explore five emerging complexities—landscape complexity, urban discontinuities, socio-ecological heterogeneity, cross-scale interactions, legacies and time lags—that need to be tackled in future research. We propose that the evolving metacommunity concept provides a powerful framework to study urban eco-evolutionary dynamics.more » « less

Our understanding of the fundamental role that soil bacteria play in the structure and functioning of Earth's ecosystems is ever expanding, but insight into the nature of interactions within these bacterial communities remains rudimentary. Bacterial facilitation may enhance the establishment, growth, and succession of eukaryotic biota, elevating the complexity and diversity of the entire soil community and thereby modulating multiple ecosystem functions. Global climate change often alters soil bacterial community composition, which, in turn, impacts other dependent biota. However, the impact of climate change on facilitation within bacterial communities remains poorly understood even though it may have important cascading consequences for entire ecosystems. The wealth of metagenomic data currently being generated gives community ecologists the ability to investigate bacterial facilitation in the natural world and how it affects ecological systems responses to climate change. Here, we review current evidence demonstrating the importance of facilitation in promoting emergent properties such as community diversity, ecosystem functioning, and resilience to climate change in soil bacterial communities. We show that a synthesis is currently missing between the abundant data, newly developed models and a coherent ecological framework that addresses these emergent properties. We highlight that including phylogenetic information, the physicochemical environment, and species‐specific ecologies can improve our ability to infer interactions in natural soil communities. Following these recommendations, studies on bacterial facilitation will be an important piece of the puzzle to understand the consequences of global change on ecological communities and a model to advance our understanding of facilitation in complex communities more generally.more » « less

Herbivores are an integral part of Arctic terrestrial ecosystems, driving ecosystem functioning and sustaining local livelihoods. In the context of accelerated climate warming and land use changes, understanding how herbivores contribute to the resilience of Arctic socio-ecological systems is essential to guide sound decision-making and mitigation strategies. While research on Arctic herbivory has a long tradition, recent literature syntheses highlight important geographical, taxonomic, and environmental knowledge gaps on the impacts of herbivores across the region. At the same time, climate change and limited resources impose an urgent need to prioritize research and management efforts. We conducted a horizon scan within the Arctic herbivory research community to identify emerging scientific and management priorities for the next decade. From 288 responses received from 85 participants in two online surveys and an in-person workshop, we identified 8 scientific and 8 management priorities centred on (a) understanding and integrating fundamental ecological processes across multiple scales from individual herbivore–plant interactions up to regional and decadal scale vegetation and animal population effects; (b) evaluating climate change feedbacks; and (c) developing new research methods. Our analysis provides a strategic framework for broad, inclusive, interdisciplinary collaborations to optimise terrestrial herbivory research and sustainable management practices in a rapidly changing Arctic.more » « less
