Tangled ecosystem models: the temptation of siren songs and silence

open access: yesScientia Marina, 2012
At a meeting on marine ecosystem modelling held in Barcelona in November 2010, a wide range of tools were introduced by their developers. An officer of the European Commission was invited to the meeting as a key client of these tools, and he severely ...

Uncertainty Management in Coupled Physical-Biological Lower Trophic Level Ocean Ecosystem Models [PDF]

open access: yesOceanography, 2013
Lower trophic level (LTL) ocean ecosystem models are important tools for understanding ocean biogeochemical variability and its role in Earth's climate system.

Coupling low and high trophic levels models: Towards a pathways-orientated approach for end-to-end models [PDF]

open access: yes, 2009
Existing models of marine ecosystems address specific issues related to the bottom-up forcing of production or to the top-down effects of fishing on a limited range of the trophic spectrum.

The Cost of Restoration as a Way of Defining Resilience: a Viability Approach Applied to a Model of Lake Eutrophication

open access: yesEcology and Society, 2004
Multiple stable states or alternative equilibria in ecological systems have been recognized since the 1960s in the ecological literature. Very often, the shift between alternative states occurs suddenly and the resource flows from these systems are ...

Top-down, bottom-up or middle-out? Avoiding extraneous detail and over-generality in marine ecosystem models [PDF]

open access: yes, 2009
The paper by Hannah et al. (this volume) invokes foodweb theory and the ideas of complexity theory to guide the construction of models of intermediate complexity, which sacrifice explicit process detail to increase the number of interacting components of

The Aquatic Organisms Diversity, Community Structure, and Environmental Conditions

open access: yesDiversity, 2019
Two main aspects of the study of diversity can be distinguished: the first is related to the inventory of living organisms, the second is related to the organization of life at the level of biotic communities.

KEYLINK: towards a more integrative soil representation for inclusion in ecosystem scale models. I. review and model concept [PDF]

open access: yesPeerJ, 2020
The relatively poor simulation of the below-ground processes is a severe drawback for many ecosystem models, especially when predicting responses to climate change and management.

Global sensitivity analysis of an end-to-end marine ecosystem model of the North Sea : factors affecting the biomass of fish and benthos [PDF]

open access: yes, 2014
Comprehensive analysis of parameter and driver sensitivity is key to establishing the credibility of models of complex systems. This is especially so for models of natural systems where experimental manipulation of the real-world to provide controlled ...
