State of the art in modelling of phosphorus in aquatic systems
TLDR
This systematic review considers how water quality and aquatic ecology models represent the phosphorus cycle and considers how models compare across domains of application, the degree to which current models are fit for purpose, how to choose between multiple alternative formulations, and how models might be improved.Abstract:
This systematic review considers how water quality and aquatic ecology models represent the phosphorus cycle. Although the focus is on phosphorus, many of the observations and discussion points here relate to aquatic ecosystem models in general. The review considers how models compare across domains of application, the degree to which current models are fit for purpose, how to choose between multiple alternative formulations, and how models might be improved. Lake and marine models have been gradually increasing in complexity, with increasing emphasis on inorganic processes and ecosystems. River models have remained simpler, but have been more rigorously assessed. Processes important in less eutrophic systems have often been neglected: these include the biogeochemistry of organic phosphorus, transformations associated with fluxes through soils and sediments, transfer rate-limited phosphorus uptake, and responses of plants to pulsed nutrient inputs. Arguments for and against increasing model complexity, physical and physiological realism are reviewed. Display Omitted The treatment of phosphorus in aquatic models is systematically reviewed.The complexity of lake, river and marine models is increasing over time.Catchment-river models tend to be simpler than lake and marine models.Performance assessment of lake and marine models is generally inadequate.Processes not included in models are discussed.read more

TL;DR: In this article, the relationship between landscape characteristics and stream water quality is investigated and the strength of this relationship can be influenced by the distance and spatial arrangement of constituent sources within the catchment, cross correlations between landscapes characteristics, and seasonality.

TL;DR: A community perspective on how to explore, exploit and evolve the diversity in aquatic ecosystem models is presented, and analogies from biodiversity research are used to analyse and interpret model diversity.

Catastrophic shifts in ecosystems.
TL;DR: Recent studies show that a loss of resilience usually paves the way for a switch to an alternative state, which suggests that strategies for sustainable management of such ecosystems should focus on maintaining resilience.

TL;DR: The GLUE procedure works with multiple sets of parameter values and allows that, within the limitations of a given model structure and errors in boundary conditions and field observations, different sets of values may be equally likely as simulators of a catchment.

Nitrogen limitation on land and in the sea: How can it occur?
TL;DR: In this paper, the authors examine both how the biogeochemistry of the nitrogen cycle could cause limitation to develop, and how nitrogen limitation could persist as a consequence of processes that prevent or reduce nitrogen fixation.

Alternative equilibria in shallow lakes
TL;DR: The reasons why alternative equilibria are theoretically expected in shallow lakes are discussed, evidence from the field is reviewed, and recent applications of this insight in lake management are evaluated.
