Abstract The scale, pace, and intensity of human activity on the planet demands radical departures from status quo to remain within planetary boundaries achieve sustainability. steering arms society including embedded financial, legal, political, governance systems must be radically realigned recognize connectivity among social, ecological, technological domains urban deliver more just, equitable, sustainable, resilient futures. We present five key principles requiring fundamental cognitive, behavioral, cultural shifts rethinking growth, efficiency, state, commons, justice needed together transform neighborhoods, cities, regions.

Abstract Tropical East Asia is home to over 1 billion people and faces massive human impacts from its rising population rapid economic growth. It has already lost more than half of forest cover the highest rates deforestation logging in tropics. Hunting trade wildlife products threaten all large many smaller vertebrates. Despite these problems, region still supports an estimated 15–25 per cent global terrestrial biodiversity thus a key focus for conservation. This book therefore deals with plants, animals, ecosystems they inhabit, as well diverse threats their survival options provides background knowledge region’s ecology needed by both specialists non-specialists put own work into broader context. The first edition was describe entire Asian tropics subtropics, southern China western Indonesia, second extended coverage include very similar Northeast India, Bangladesh, Bhutan. third updates contents gives prominence Anthropocene possible conservation responses. accessible style, comprehensive coverage, engaging illustrations make this advanced textbook essential read senior undergraduate graduate-level students studying tropics, authoritative reference professional ecologists, conservationists, interested amateurs worldwide.

The human dimension of biodiversity changes on islands

Science, Journal Year: 2021, Volume and Issue: 372(6541), P. 488 - 491

Published: April 29, 2021

Islands are among the last regions on Earth settled and transformed by human activities, they provide replicated model systems for analysis of how people affect ecological functions. By analyzing 27 representative fossil pollen sequences encompassing past 5000 years from islands globally, we quantified rates vegetation compositional change before after arrival. After arrival, turnover accelerate a median factor 11, with faster colonized in 1500 than those earlier. This global anthropogenic acceleration suggests that trajectories continuing change. Strategies biodiversity conservation ecosystem restoration must acknowledge long duration impacts degree to which changes today differ prehuman dynamics.

Navigating Ecological Transformation: Resist–Accept–Direct as a Path to a New Resource Management Paradigm

BioScience, Journal Year: 2021, Volume and Issue: 72(1), P. 16 - 29

Published: June 7, 2021

Abstract Natural resource managers worldwide face a growing challenge: Intensifying global change increasingly propels ecosystems toward irreversible ecological transformations. This nonstationarity challenges traditional conservation goals and human well-being. It also confounds longstanding management paradigm that assumes future reflects the past. As once-familiar conditions disappear, need new approach to guide decision-making. The resist–accept–direct (RAD) framework, designed for by managers, identifies options have responding helps them make informed, purposeful, strategic choices in this context. Moving beyond diversity complexity of myriad emerging frameworks, RAD is simple, flexible, decision-making tool encompasses entire decision space stewarding transforming ecosystems. Through shared application common approach, framework can help wider natural research community build robust, habits mind necessary new, twenty-first-century paradigm.

Global soil profiles indicate depth-dependent soil carbon losses under a warmer climate

Soil organic carbon (SOC) changes under future climate warming are difficult to quantify in situ. Here we apply an innovative approach combining space-for-time substitution with meta-analysis SOC measurements 113,013 soil profiles across the globe estimate effect of on steady-state stocks.

Managing for RADical ecosystem change: applying the Resist‐Accept‐Direct (RAD) framework

Frontiers in Ecology and the Environment, Journal Year: 2021, Volume and Issue: 19(8), P. 461 - 469

Published: July 8, 2021

Ecosystem transformation involves the emergence of persistent ecological or social–ecological systems that diverge, dramatically and irreversibly, from prior ecosystem structure function. Such transformations are occurring at increasing rates across planet in response to changes climate, land use, other factors. Consequently, a dynamic view processes accommodates rapid, irreversible change will be critical for effectively conserving fish, wildlife, natural resources, maintaining services. However, managing ecosystems toward states with novel function is an inherently unpredictable difficult task. Managers navigating can benefit considering broader objectives, beyond traditional focus on resisting change, by also whether accepting inevitable directing it along some desirable pathway more feasible (that is, practical appropriate) under circumstances (the RAD framework). By explicitly acknowledging implementing iterative approach, resource managers deliberate strategic addressing profound change.

Getting ahead of climate change for ecological adaptation and resilience

Science, Journal Year: 2022, Volume and Issue: 376(6600), P. 1421 - 1426

Published: June 23, 2022

Changing the course of Earth's climate is increasingly urgent, but there also a concurrent need for proactive stewardship adaptive capacity rapidly changing biosphere. Adaptation ultimately underpins resilience complex systems; species, communities, and ecosystems shift evolve over time. Yet oncoming changes will seriously challenge current natural resource management conservation efforts. We review forward-looking approaches to enable adaptation resilience. Key opportunities include expanding beyond preservationist by including those that facilitate ecological change. Conservation should not just focus on change losers emerging opportunities. Local efforts conserve biodiversity generate habitat complexity help maintain diversity future options an unpredictable future.
