Modular Ecosystem Modeling

open access: yesEnvironmental Modelling & Software, 2004
The Library of Hydro-Ecological Modules (LHEM, http://giee.uvm.edu/LHEM) was designed to create flexible landscape model structures that can be easily modified and extended to suit the requirements of a variety of goals and case studies. The LHEM includes modules that simulate hydrologic processes, nutrient cycling, vegetation growth, decomposition ...

The case for marine ecosystem models of intermediate complexity [PDF]

open access: yes, 2009
Marine ecosystem models are reasonably proficient at simulating physically-driven features such as spring blooms. However, the demands on these models are shifting to complex biological issues such as functional diversity, and changes in ecosystems and ...

High precipitation rates increase potassium density in plant communities in the Tibetan Plateau

open access: yesCommunications Earth & Environment, 2023
Potassium is essential for plant growth. However, our understanding of potassium in plant materials is limited due to a lack of systematic studies. Here, we measured potassium content in 2,040 ecosystem communities during the period 2019-2021 applying ...

Ecological Engineering Projects Shifted the Dominance of Human Activity and Climate Variability on Vegetation Dynamics

open access: yesRemote Sensing, 2022
Global greening and its eco-environmental outcomes are getting mounting international focus. The important contribution of China to the global greening is highly appreciated. However, the basic driving forces are still elusive. The Loess Plateau (LP) and

Modelling an ecosystem: The example of agro-ecosystems

open access: yesEcological Modelling, 2011
Abstract Methods to predict ecosystem responses to changing environmental conditions, including options for mitigation and management, are vital for scientists and policy makers. We propose that modelling ecosystems by grouping species into trophic-functional types has great utility, because it is potentially generic and applicable to any ecosystem ...

Spatial variation and mechanisms of leaf water content in grassland plants at the biome scale: evidence from three comparative transects

open access: yesScientific Reports, 2021
Leaf water content (LWC) has important physiological and ecological significance for plant growth. However, it is still unclear how LWC varies over large spatial scale and with plant adaptation strategies.

Dynamic Threshold of Carbon Phenology in Two Cold Temperate Grasslands in China

open access: yesRemote Sensing, 2021
Plant phenology, especially the timing of the start and the end of the vegetation growing season (SOS and EOS), plays a major role in grassland ecosystem carbon cycles.

Dysfunctionality in ecosystem models: an underrated pitfall? [PDF]

open access: yes, 2009
Including causal mechanisms in model formulations is the key to predictive success. Yet it would appear that much of our latest (specifically ecophysiological) understanding accruing from phenomological evidence and experimental work is often not being ...

Aboveground biomass estimation at different scales for subtropical forests in China

open access: yesBotanical Studies, 2017
Background The accurate estimation of forest biomass at different scales is the critical step in the assessment of forest carbon stocks. We used three models at increasing scales: allometric model at ecoregional scale (model 1), dummy variable allometric
