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.

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.

Abstract Intensifying global change is propelling many ecosystems toward irreversible transformations. Natural resource managers face the complex task of conserving these important resources under unprecedented conditions and expanding uncertainty. As once familiar ecological disappear, traditional management approaches that assume future will reflect past are becoming increasingly untenable. In present article, we place adaptive within resist–accept–direct (RAD) framework to assist informed risk taking for transforming ecosystems. This approach empowers use techniques associated with in unfamiliar territory ecosystem transformation. By providing a common lexicon, it gives decision makers agency revisit objectives, consider new system trajectories, discuss RAD strategies relation current state direction change. Operationalizing requires periodic review update actions objectives; monitoring, experimentation, pilot studies; bet hedging better identify tolerate risks.

Abstract Conservation practices during the first decade of millennium predominantly focused on resisting changes and maintaining historical or current conditions, but ever-increasing impacts from climate change have highlighted need for transformative action. However, little empirical evidence exists what kinds conservation actions aimed specifically at adaptation are being implemented in practice, let alone how these are. In response, we propose trial a novel typology—the R–R–T scale, which improves existing concepts Resistance, Resilience, Transformation—that enables practical application contested terms assessment whether to extent shift toward action is occurring. When applying scale case study 104 projects funded since 2011, find trend towards transformation that varies across ecosystems.

Genetic studies suggest that sequential dissemination from a primary metastasis, usually at the bone, is major route of metastatic progression in early, radically resected cancer. Disseminated tumor cells (DTCs) can likely infiltrate but not grow, and may remain dormant once disseminated for extended intervals (from months to decades). The stationary nature DTCs prevents them being successfully treated as an asymptomatic residual disease adjuvant setting; critically, they eventually relapse, adapt, develop therapy resistance, causing incurable overt metastasis. Metastatic lesions first appear one tissue, which invigorates further other organs, with fatal outcome. Clinical genetic data now indicate organ seed secondary metastases organs: words, metastasis arising Herein we discuss recent insight into cell dormancy mechanisms, survival, communication local microenvironment, eventual changes endow capacity expand colonize sites.
