Examining soil/ecosystem respiration in the Amazon basin
Environmental Earth Sciences, 2017The Brazilian–German project EcoRespira-Amazon currently conducts a study of soil respiration and soil chemistry in the Brazilian Amazon basin that comparatively examines forested land with post-forest land cover. The Amazon region, long recognized as a key component of the global carbon cycle and a tipping point in the global climate system, covers an

Underestimation of soil respiration in a desert ecosystem
CATENA, 2018Abstract Soil respiration (Rs), conventionally considered as net soil CO2 flux, is an important link in the terrestrial carbon cycle. However, existing estimates of Rs in drylands may be erroneous, because of the abiotic soil CO2 flux. This may seriously hamper our understanding of the carbon cycle of desert ecosystems.

Plant decomposition and soil respiration in terrestrial ecosystems
The Botanical Review, 1977This review deals with methodological approaches, measured rates, and environmental control of two major interdependent processes regulating the structure and function of terrestrial ecosystems, viz., plant decomposition and soil respiration. Both these processes have been evaluated through indirect assessments as well as through direct measurements ...

Partitioning of ecosystem respiration in a beech forest ecosystem
2010Wir charakterisierten die Bodenatmung (CO2) und ihre isotopische Zusammensetzung (13C) eines temperaten Buchenwaldes (Fagus sylvatica) im Tages- bzw. Jahresverlauf und untersuchten die Aufteilung der Bodenatmung in ihre autotrophen und heterotrophen Anteile.

Differences in soil respiration between different tropical ecosystems
Applied Soil Ecology, 2006We examined the relationship between soil respiration rate and environmental determinants in three types of tropical forest ecosystem—primary forest, secondary forest, and an oil palm plantation in the Pasoh Forest Reserve on the Malaysian Peninsula.

Production, Respiration and Net Ecosystem Metabolism in U.S. Estuaries
Environmental Monitoring and Assessment, 2003Primary production, respiration, and net ecosystem metabolism (NEM) are useful indicators of ecosystem level trophic conditions within estuaries. In this study, dissolved oxygen data collected every half hour between January 1996 to December 1998 by the National Estuarine Research Reserve System Wide Monitoring Program were used to calculate primary ...

Interacting Controls on Ecosystem Photosynthesis and Respiration in Contrasting Peatland Ecosystems
2013Photosynthesis in moss contributes significantly to carbon gain in northern peatland ecosystems. In turn, these northern peatland ecosystems contain a large fraction of the global soil carbon stock, which has been suggested to be vulnerable to warming and drying associated with climate change.

Ecosystem configurations consequent on the maximum respiration hypothesis
Ecological Modelling, 1995The Maximum Respiration Hypothesis (MRH) asserts that matured ecosystems organize their configuration to maximize community respiration. Hence the object of the hypothesis is not individual living organisms but the whole ecosystem. In this paper we use two types of ecosystem models to show how the MRH works in ecosystems.

Isotopic (13C and 14C) tracers in ecosystem respiration
2007Terrestrial ecosystems are expected to respond to global warming with the very real possibility that they may add to global atmospheric anthropogenic CO[2] emissions, thus exacerbating climate change. Isotopes of carbon in ecosystem respiration provide valuable information regarding the contribution of individual sources. A portable sampling system was
