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

Ecology 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 ...

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

PeerJ, 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.

The Aquatic Organisms Diversity, Community Structure, and Environmental Conditions

Diversity, 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.

Comparing machine learning-derived global estimates of soil respiration and its components with those from terrestrial ecosystem models

Environmental Research Letters, 2021
The CO _2 efflux from soil (soil respiration (SR)) is one of the largest fluxes in the global carbon (C) cycle and its response to climate change could strongly influence future atmospheric CO _2 concentrations.

Model Selection for Ecosystem Respiration Needs to Be Site Specific: Lessons from Grasslands on the Mongolian Plateau

Land, 2022
Selecting an appropriate model for simulating ecosystem respiration is critical in modeling the carbon cycle of terrestrial ecosystems due to their magnitude and high variations in time and space.

Characterization of river plume dynamics for a better water quality management

Frontiers in Marine Science
Excessive riverine nutrient inputs are a main driver of eutrophication in marine waters. Thus, identifying areas most affected by river plumes is a key challenge for effective water quality management.
