Ecosystem tipping points in an evolving world

Dakos, V., Matthews, B., Hendry, A.P., Levine, J., et.al.

2019 - Journal / article

There is growing concern over tipping points arising in ecosystems because of the crossing of environmental thresholds. Tipping points lead to abrupt and possibly irreversible shifts between alternative ecosystem states, potentially incurring high societal costs. Trait variation in populations is central to the biotic feedbacks that maintain alternative ecosystem states, as they govern the responses of populations to environme...

Scaling functional traits to ecosystem processes: Towards a mechanistic understanding in peat mosses

Mazziotta, A., Granath, G., Rydin, H., Bengtsson, F. & Norberg, J.

2018 - Journal / article

1. The role of trait trade -offs and environmental filtering in explaining the variability in 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 subse -quently ecosystem...

Analytically tractable climate–carbon cycle feedbacks under 21st century anthropogenic forcing

Lade, S. J., Donges, J. F., Fetzer, I., Anderies, J. M., Beer, C., Cornell, S. E., Gasser, T., Norberg, J., Richardson, K., Rockström, J., and Steffen, W.

Changes to climate–carbon cycle feedbacks may significantly affect the Earth system’s response to greenhouse gas emissions. These feedbacks are usually analysed from numerical output of complex and arguably opaque Earth system models. Here, we construct a stylised global climate–carbon cycle model, test its output against comprehensive Earth system models, and investigate the strengths of its climate–carbon cycle feedbacks ...

Strategies for sustainable management of renewable resources during environmental change

Lindkvist E., Ekeberg, Ö., Norberg, J.

2017 - Journal / article

As a consequence of global environmental change, management strategies that can deal with unexpected change in resource dynamics are becoming increasingly important. In this paper we undertake a novel approach to studying resource growth problems using a computational form of adaptive management to find optimal strategies for prevalent natural resource management dilemmas. We scrutinize adaptive management, or learning-by-doin...
