Multiple Stable States and Regime Shifts - Environmental Science - Oxford Bibliographies 3/30/18, 10:15 AM Multiple Stable States and Regime Shifts James Heffernan, Xiaoli Dong, Anna Braswell LAST MODIFIED: 28 MARCH 2018 DOI: 10.1093/OBO/9780199363445-0095 Introduction Why do ecological systems (populations, communities, and ecosystems) change suddenly in response to seemingly gradual environmental change, or fail to recover from large disturbances? Why do ecological systems in seemingly similar settings exhibit markedly different ecological structure and patterns of change over time? The theory of multiple stable states in ecological systems provides one potential explanation for such observations. In ecological systems with multiple stable states (or equilibria), two or more configurations of an ecosystem are self-maintaining under a given set of conditions because of feedbacks among biota or between biota and the physical and chemical environment. The resulting multiple different states may occur as different types or compositions of vegetation or animal communities; as different densities, biomass, and spatial arrangement; and as distinct abiotic environments created by the distinct ecological communities. Alternative states are maintained by the combined effects of positive (or amplifying) feedbacks and negative (or stabilizing feedbacks). While stabilizing feedbacks reinforce each state, positive feedbacks are what allow two or more states to be stable. Thresholds between states arise from the interaction of these positive and negative feedbacks, and define the basins of attraction of the alternative states. These feedbacks and thresholds may operate over whole ecosystems or give rise to self-organized spatial structure. The combined effect of these feedbacks is also what gives rise to ecological resilience, which is the capacity of ecological systems to absorb environmental perturbations while maintaining their basic structure and function. -

Ecosystem Management
Ecosystem management United Nations Environment Programme An overview Human well-being depends on the health of ecosystems. An ecosystem is a dynamic complex of plants, animals, microorganisms and their nonliving environment, of which people are an integral part. The benefits that we derive from nature and rely on every day, from timber and food to water and climate regulation, are all ecosystem services. In 2005, the UN Millennium Ecosystem Assessment Our goals examined a group of 24 ecosystem services and found that 15 were being degraded or used unsustainably. This decline The UNEP Ecosystem Management sub-programme helps in services disproportionately affects the world’s most countries use the ecosystem approach to enhance human disadvantaged and vulnerable people. And as these problems, well-being.

SHADRIN * Kovalevsky Institute of Marine Biological Research, Russian Academy of Sciences, Sevastopol 299011, Russia Received Nov. 1, 2017; accepted in principle Jan. 4, 2018; accepted for publication Jan. 29, 2018 © Chinese Society for Oceanology and Limnology, Science Press and Springer-Verlag GmbH Germany, part of Springer Nature 2018 Abstract Our sustainable environmental management must be based on adequate ecological concepts. The question arises: what concept is better to use for understanding and management of ecosystems? To look for an answer, we concentrate our attention on saline lakes. Every ecosystem has several alternative stable states and may demonstrate regime shifts, which are large, abrupt, persistent changes in the structure and function of a system. To understand the dynamics of ecosystems the Concept of Multiplicity of Ecosystem Alternative Stable States as a new ecological paradigm has been developed recently. The author analyzes the emerging paradigm using the case of saline lakes, and discusses how to base our adaptive environmental management on the developing paradigm. Diff erent issues of development of the concept and its application to salinology as a scientifi c basis of an integrated management of a saline lake and its watershed are discussed. The concept may serve as one of the key theoretical elements of the scientifi c basis in sustainable environmental management.

Anticipating Interactions of Landscape Disturbance and Climate Change
Are Madrean Ecosystems Approaching Tipping Points? Anticipating Interactions of Landscape Disturbance and Climate Change Donald A. Falk School of Natural Resources and the Environment, University of Arizona, Tucson, Arizona Abstract—Contemporary climate change is driving transitions in many Madrean ecosystems, but the time scale of these changes is accelerated greatly by severe landscape disturbances such as wildfires and insect outbreaks. Landscape-scale disturbance events such as wildfires interact with prior disturbance patterns and landscape structure to catalyze abrupt transitions to novel ecosystem configurations. These reorganized landscapes are characterized by new disturbance regimes and potentially dramatic departures in species diversity and distributions, community composition, carbon storage, landscape mesoclimate, and soil and hydrologic processes. Post-transition ecosystems can be highly resilient in their altered state, and resistant to return to pre-disturbance conditions in the current and near-term climate regime, possibly representing alternative metastable states. Severe landscape disturbance interacts with, and may be driven by, climate variation to govern ecosystem dynamics and large-scale ecosystem change. We present a conceptual model organized around six key attributes that may drive ecosystems to rapid change and novel trajectories. Background Post-fire ecological transitions have been observed in multiple sites in Southwestern North America.

Changing Forest Values and Ecosystem Management
lqqY Sociery and Narurul resource^, Volume 7,pp. 515-533 Pnnted In the UK. All righe reserved. Changing Forest Values and Ecosystem Management DAVID N. BENGSTON USDA Forest Service North Central Forest Experiment Station St. Paul, Minnesota, USA There is substantial evidence that we are currently in a period of rapid and significant change in forest values. Some have charged that managing forests in ways that are re- sponsive to diverse and changing forest values is the main challenge faced by public forest managers. To tackle this challenge, we need to address the following questions: (I) What is the nature of forest values? That is, can all forest values be reduced to a single dimension, as assumed in utilitarian-based traditional forestry and economics, or are these values multidimensional and incommensurate? (2) What specific values are involved? (3) What is the structure of forest values? That is, how are they related to each other in value systems? (4)How and why have forest values changed over time? and (5) What do changing forest values imply for ecosystem management up- proaches? This article discusses key issues related to these questions. Keywords ecosystem management, forest values, methodological pluralism, multi- dimensionality, new forestry A growing number of social scientists and other observers have discerned a fundamental shift in environmental values in recent decades. A "new environmental paradigm" of hu- mans and nature is challenging the longstanding constellation of values, attitudes, and beliefs that form the "dominant social paradigm" through which many in industrialized societies view the world.' The dominant social paradigm emphasizes economic growth, control of nature, faith in science and technology, ample reserves of natural resources, the substitutability of resources, and a dominant role for experts in decision making. -
