Understanding soil and ecosystem respiration in a dune-meadow cascade ecosystem
Ecological ProcessesArid and semi-arid regions, which account for more than 30% of the Earth's land area, increasingly dominate the spatiotemporal trends in global carbon fluxes. The Horqin Sandy Land is a typical semi-arid fragile ecosystem in northern China. Understanding

Warming homogenizes apparent temperature sensitivity of ecosystem respiration. [PDF]
Sci Adv, 2021 Warming-induced carbon loss may be less than previously assumed due to temperature sensitivity homogenization in a warming world.

Linking denitrification with ecosystem respiration in mountain streams [PDF]
Limnology and Oceanography Letters, 2019 Rivers denitrify a portion of their nitrate (NO3−) load, but estimates are difficult using microcosm or reach‐scale measurements that require specific biogeochemical and hydrologic conditions.

Widespread inhibition of daytime ecosystem respiration. [PDF]
Nat Ecol Evol, 2019 The global land surface absorbs about a third of anthropogenic emissions each year, due to the difference between two key processes: ecosystem photosynthesis and respiration. Despite the importance of these two processes, it is not possible to measure either at the ecosystem scale during the daytime.

Temperature thresholds of ecosystem respiration at a global scale [PDF]
Nature Ecology & Evolution, 2021 Ecosystem respiration is a major component of the global terrestrial carbon cycle and is strongly influenced by temperature. The global extent of the temperature-ecosystem respiration relationship, however, has not been fully explored. Here, we test linear and threshold models of ecosystem respiration across 210 globally distributed eddy covariance ...

Snow melt stimulates ecosystem respiration in Arctic ecosystems
Global Change Biology, 2020 AbstractCold seasons in Arctic ecosystems are increasingly important to the annual carbon balance of these vulnerable ecosystems. Arctic winters are largely harsh and inaccessible leading historic data gaps during that time. Until recently, cold seasons have been assumed to have negligible impacts on the annual carbon balance but as data coverage ...

Ecosystem‐level controls on root‐rhizosphere respiration [PDF]
New Phytologist, 2013 SummaryRecent advances in the partitioning of autotrophic from heterotrophic respiration processes in soils in conjunction with new high temporal resolution soil respiration data sets offer insights into biotic and environmental controls of respiration. Besides temperature, many emerging controlling factors have not yet been incorporated into ecosystem‐

Observed and modelled ecosystem respiration and gross primary production of a grassland in southwestern France [PDF]
Biogeosciences, 2010 In this work, the rich dataset acquired at the SMOSREX experimental site is used to enhance the A-gs version of the Interactions between Soil, Biosphere and Atmosphere (ISBA) model.

When does temperature matter for ecosystem respiration?
Environmental Research Communications, 2021 Abstract The temperature response of ecosystem processes is key to understand and predict impacts of climate change. This is especially true for respiration, given its high temperature sensitivity and major role in the global carbon cycle.
