Comparison of boreal ecosystem model sensitivity to variability in climate and forest site parameters [PDF]

open access: yes, 2001
Ecosystem models are useful tools for evaluating environmental controls on carbon and water cycles under past or future conditions. In this paper we compare annual carbon and water fluxes from nine boreal spruce forest ecosystem models in a series of ...

What controls forest litter decomposition? A coordinated distributed teabag experiment across ten mountains

open access: yesEcography, EarlyView.
Litter decomposition in mountainous forest ecosystems is an essential process that affects carbon and nutrient cycling. However, the contribution of litter decomposition to terrestrial ecosystems is difficult to estimate accurately because of the limited comparability of different studies and limited data on local microclimatic and non‐climatic factors.

Global spatiotemporal distribution of soil respiration modeled using a global database [PDF]

open access: yesBiogeosciences, 2015
The flux of carbon dioxide from the soil to the atmosphere (soil respiration) is one of the major fluxes in the global carbon cycle. At present, the accumulated field observation data cover a wide range of geographical locations and climate conditions ...

The diversity and ecological role of protozoa in fresh waters [PDF]

open access: yes, 1997
Protozoa feed on and regulate the abundance of most types of aquatic microorganisms, and they are an integral part of all aquatic microbial food webs. Being so small, aerobic protozoa thrive at low oxygen tensions, where they feed (largely unaffected by ...

Growth limiting conditions and denitrification govern extent and frequency of volume detachment of biofilms [PDF]

open access: yes, 2013
This study aims at evaluating the mechanisms of biofilm detachment with regard of the physical properties of the biofilm. Biofilms were developed in Couette–Taylor reactor under controlled hydrodynamic conditions and under different environmental growth ...

Amazonian drought of 2023: Environmental conditions relevant to fishes

open access: yesJournal of Fish Biology, EarlyView.
Abstract This paper provides a platform for the following studies within this Special Issue. ‘Ecophysiology of fishes in the two great tributaries of the Amazon in the Anthropocene’. It documents the water quality conditions and accompanying zooplankton community structure and biomass relative to fish health in the Rio Negro and Rio Solimões during the

Various responses of global heterotrophic respiration to variations in soil moisture and temperature enhance the positive feedback on atmospheric warming

open access: yesCommunications Earth & Environment
The ratio of soil heterotrophic respiration to total soil respiration (Rh/Rs) is critical for soil carbon pool stability and atmosphere-biosphere exchanges, yet its spatiotemporal dynamics and responses to environmental drivers remain poorly constrained.

Constraining a complex biogeochemical model for CO2 and N2O emission simulations from various land uses by model–data fusion [PDF]

open access: yes, 2017
This study presents the results of a combined measurement and modelling strategy to analyse N2O and CO2 emissions from adjacent arable land, forest and grassland sites in Hesse, Germany.

Fruit respiration: putting alternative pathways into perspective

open access: yesNew Phytologist, EarlyView.
Summary Over the past century, research has significantly advanced our understanding of fruit respiration, from (eco)physiological processes to molecular mechanisms. This review focuses on the functional relevance and regulatory roles of mitochondrial alternative respiratory pathways (ARPs) during fruit growth and ripening.
