Data from: Regime shifts in marine communities: a complex systems perspective on food web dynamics

Johanna Yletyinen, Örjan Bodin, Marie Nordström, Benjamin Weigel, Erik Bonsdorff & Thorsten Blenckner
Species composition and habitats are changing at unprecedented rates in the world’s oceans, potentially causing entire food webs to shift to structurally and functionally different regimes. Despite the severity of these regime shifts, elucidating the precise nature of their underlying processes has remained difficult. We address this challenge with a new analytic approach to detect and assess the relative strength of different driving processes in food webs. Our study draws on complexity theory, and integrates...

AgentEx

Nanda Wijermans, Maja Schlüter, Caroline Schill & Therese Lindahl
AgentEx aims to advance understanding of group processes for sustainable management of a common pool resource (CPR) in dynamic social-ecological environments. It targets to qualitatively reproduce and explain patterns observed in behavioural CPR laboratory experiments. AgentEx (v1.0) represents an explanation that is characterised by three individual-level factors: individual ecological knowledge, confidence in knowledge and social skills that interact to determine individual and group knowledge as the outcomes of communication/knowledge sharing and knowledge updating.

Data from: Biocultural approaches to sustainability: a systematic review of the scientific literature

Jan Hanspach, L. Jamila Haider, Elisa Oteris-Rozas, Anton Stahl Olafsson, Natalie Gulsrud, Chris Raymond, Mario Torralba, Berta Martín-López, Claudia Bieling, María García Martín, Christian Albert, Thomas Beery, Nora Fagerholm, Isabel Díaz-Reviriego, Annika Drews-Shambroom & Tobias Plieninger
Current sustainability challenges demand approaches that acknowledge a plurality of human-nature interactions and worldviews, for which biocultural approaches are considered appropriate and timely. This systematic review analyses the application of biocultural approaches to sustainability in scientific journal articles published between 1990 and 2018 through a mixed methods approach combining qualitative content analysis and quantitative multivariate methods. The study identifies seven distinct biocultural lenses, i.e. different ways of understanding and applying biocultural approaches, which to different...

Data from: Scaling functional traits to ecosystem processes: towards a mechanistic understanding in peat mosses

Adriano Mazziotta, Gustaf Granath, Håkan Rydin, Fia Bengtsson & Jon Norberg
1. The role of trait trade-offs and environmental filtering in explaining the variability of functional traits and ecosystem processes has received considerable attention for vascular plants but less so for bryophytes. Thus, we do not know whether the same forces also shape the phenotypic variability of bryophytes. Here we assess how environmental gradients and trade-offs shape functional traits and subsequently ecosystem processes for peat mosses (Sphagnum), a globally important plant genus for carbon accumulation. We...

Small-Trade Model

Emilie Lindkvist & Blanca Gonzalez García-Mon
The purpose of this model is to understand the role of trade networks and their interaction with different fish resources, for fish provision. The model is developed based on a multi-methods approach, combining agent-based modeling, network analysis and qualitative data based on a small-scale fisheries study case. The model can be used to investigate both how trade network structures are embedded in a social-ecological context and the trade processes that occur within them, to analyze...

Data from: Climate and fishing steer ecosystem regeneration to uncertain economic futures

Thorsten Blenckner, Marcos Llope, Christian Möllmann, Rudi Voss, Martin F. Quaas, Michele Casini, Martin Lindegren, Carl Folke, Nils Chr. Stenseth & C. Mollmann
Overfishing of large predatory fish populations has resulted in lasting restructurings of entire marine food webs worldwide, with serious socio-economic consequences. Fortunately, some degraded ecosystems show signs of recovery. A key challenge for ecosystem management is to anticipate the degree to which recovery is possible. By applying a statistical food-web model, using the Baltic Sea as a case study, we show that under current temperature and salinity conditions, complete recovery of this heavily altered ecosystem...

Data from: Combining fish and benthic communities into multiple regimes reveals complex reef dynamics

Kappel, Kendra Karr, John N. Kittinger, Albert V. Norström, Magnus Nyström, Kirsten L. L. Oleson, Kostantinos A. Stamoulis, Crow White, Ivor D. Williams & Kimberly A. Selkoe
Coral reefs worldwide face an uncertain future with many reefs reported to transition from being dominated by corals to macroalgae. However, given the complexity and diversity of the ecosystem, research on how regimes vary spatially and temporally is needed. Reef regimes are most often characterised by their benthic components; however, complex dynamics are associated with losses and gains in both fish and benthic assemblages. To capture this complexity, we synthesised 3,345 surveys from Hawai‘i to...
