Regime Shifts in the Anthropocene: Drivers, Risk, and Resilience
Supplementary Information for Regime Shifts in the Anthropocene: drivers, risk, and resilience by Juan-Carlos Rocha, Garry D. Peterson & Reinette O. Biggs. This document presents a worked example of a regime shift. We first provide a synthesis of the regime shift dynamics and a causal loop diagram (CLD). We then compare the resulting CLD with other regime shifts to make explicit the role of direct and indirect drivers. For each regime shift analyses in this study we did a similar literature synthesis and CLD which are available in the regime shift database. A longer version of this working example and CLDs can be found at www.regimeshifts.org. 1. Kelps transitions Summary. Kelp forests are marine coastal ecosystems located in shallow areas where large macroalgae ecologically engineer the environment to produce a coastal marine environmental substantially different from the same area without kelp. Kelp forests can undergo a regime shift to turf-forming algae or urchin barrens. These shift leads to loss of habitat and ecological complexity. Shifts to turf algae are related to nutrient input, while shifts to urchin barrens are related to trophic-level changes. The consequent loss of habitat complexity may affect commercially important fisheries. Managerial options include restoring biodiversity and installing wastewater treatment plants in coastal zones. Kelps are marine coastal ecosystems dominated by macroalgae typically found in temperate areas. This group of species form submarine forests with three or four layers, which provides different habitats to a variety of species. These forests maintain important industries like lobster and rockfish fisheries, the chemical industry with products to be used in e.g. -

Multiple Stable States and Regime Shifts - Environmental Science - Oxford Bibliographies 3/30/18, 10:15 AM
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. -

Yet it is largely unknown how these transitions will interact, whether the occurrence of one will increase the likelihood of another, or simply correlate at distant places. Here we explore two types of cascading effects: domino effects create one-way dependencies, while hidden feedbacks produce two-way interactions; and compare them with the control case of driver sharing which can induce correlations. Using 30 regime shifts described as networks, we show that 45% of the pair-wise combinations of regime shifts present at least one plausible structural interdependence. Driver sharing is more common in aquatic systems, while hidden feedbacks are more commonly found in terrestrial and Earth systems tipping points. The likelihood of cascading effects depends on cross-scale interactions, but differs for each cascading effect type. Regime shifts should not be studied in isolation: instead, methods and data collection should account for potential teleconnections. -
Regime Shifts Database Template for Capturing Generic Examples of Regime Shifts

REGIME SHIFTS DATABASE GENERIC REGIME SHIFTS TEMPLATE GREEN = Free text, paragraph style BLUE = Free text, brief keywords or phrases RED = Choose from predefined keyword options 1. Regime shift name Short, succinct name for the type of regime shift. Try to include a brief reference to both regimes (e.g. clear to turbid water). The regime shift types should be generalized descriptions of the dynamics of a particular kind of RS as observed over multiple case studies, rather than a description of the dynamics that occurred in a particular case (e.g. Lake Eutrophication in Lake Mendota). However, for large-scale regional or global RS the case may be unique (e.g. collapse of the thermohaline circulation) and can then be described in unique terms. 2.

The concept has roots in complexity science and its ecological applications and is increasingly applied to intertwined social and ecological phenomena. Yet, what exactly is a regime shift? We explore this question at three nested levels. First, we propose a broad, contingent, multi-perspective epistemological basis for the concept, seeking to build bridges between its complexity theory origins and critiques from science studies, political ecology, and environmental history. -

Recycled Fish Sculpture (.PDF)
Recycled Fish Sculpture Name:__________ Fish: are a paraphyletic group of organisms that consist of all gill-bearing aquatic vertebrate animals that lack limbs with digits. At 32,000 species, fish exhibit greater species diversity than any other group of vertebrates. Sculpture: is three-dimensional artwork created by shaping or combining hard materials—typically stone such as marble—or metal, glass, or wood. Softer ("plastic") materials can also be used, such as clay, textiles, plastics, polymers and softer metals. They may be assembled such as by welding or gluing or by firing, molded or cast. Researched Photo Source: Alaskan Rainbow STEP ONE: CHOOSE one fish from the attached Fish Names list. Trout STEP TWO: RESEARCH on-line and complete the attached K/U Fish Research Sheet. STEP THREE: DRAW 3 conceptual sketches with colour pencil crayons of possible visual images that represent your researched fish. STEP FOUR: Once your fish designs are approved by the teacher, DRAW a representational outline of your fish on the 18 x24 and then add VALUE and COLOUR . CONSIDER: Individual shapes and forms for the various parts you will cut out of recycled pop aluminum cans (such as individual scales, gills, fins etc.) STEP FIVE: CUT OUT using scissors the various individual sections of your chosen fish from recycled pop aluminum cans. OVERLAY them on top of your 18 x 24 Representational Outline 18 x 24 Drawing representational drawing to judge the shape and size of each piece. STEP SIX: Once you have cut out all your shapes and forms, GLUE the various pieces together with a glue gun.
