Seasonal and Inter-Annual Variations in Carbon Dioxide Exchange over an Alpine Grassland in the Eastern Qinghai-Tibetan Plateau. [PDF]

PLoS ONE, 2016
This work analyzed carbon dioxide exchange and its controlling factors over an alpine grassland on the eastern Qinghai-Tibetan Plateau. The main results show that air temperature and photosynthetically active radiation are two dominant factors ...

Controls on winter ecosystem respiration in temperate and boreal ecosystems [PDF]

Biogeosciences, 2011
Abstract. Winter CO2 fluxes represent an important component of the annual carbon budget in northern ecosystems. Understanding winter respiration processes and their responses to climate change is also central to our ability to assess terrestrial carbon cycle and climate feedbacks in the future. However, the factors influencing the spatial and temporal

Variation in seagrass meadow respiration measured by aquatic eddy covariance

Limnology and Oceanography Letters, 2022
Accurate daily metabolic estimates of respiration, gross primary production, and net ecosystem metabolism are necessary to assess ecosystem health and blue carbon contributions of vegetated coastal ecosystems.

Autotrophic component of soil respiration is repressed by drought more than the heterotrophic one in dry grasslands [PDF]

Biogeosciences, 2016
Summer droughts projected to increase in central Europe due to climate changes strongly influence the carbon cycle of ecosystems. Persistent respiration activities during drought periods are responsible for a significant carbon loss, which may turn the ...

Bomb-¹⁴C analysis of ecosystem respiration reveals that peatland vegetation facilitates release of old carbon [PDF]

, 2009
The largest terrestrial-to-atmosphere carbon flux is respired CO₂. However, the partitioning of soil and plant sources, understanding of contributory mechanisms, and their response to climate change are uncertain.

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

, 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 ...

Ecosystem respiration, methane and nitrous oxide fluxes from ecotopes in a rewetted extracted peatland in Sweden [PDF]

Mires and Peat, 2016
Ecosystem respiration (carbon dioxide; CO2), methane (CH4) and nitrous oxide (N2O) fluxes to the atmosphere were determined using an opaque closed chamber method within various ecotopes (vegetation covered, bare peat and open water) in a rewetted ...

Predicting Soil Respiration from Plant Productivity (NDVI) in a Sub-Arctic Tundra Ecosystem

Remote Sensing, 2021
Soils represent the largest store of carbon in the biosphere with soils at high latitudes containing twice as much carbon (C) than the atmosphere. High latitude tundra vegetation communities show increases in the relative abundance and cover of deciduous

Environmental drivers of increased ecosystem respiration in a warming tundra. [PDF]

Nature
AbstractArctic and alpine tundra ecosystems are large reservoirs of organic carbon1,2. Climate warming may stimulate ecosystem respiration and release carbon into the atmosphere3,4. The magnitude and persistency of this stimulation and the environmental mechanisms that drive its variation remain uncertain5–7.

Growing season CO2 fluxes from a drained peatland dominated by Molinia caerulea [PDF]

Mires and Peat, 2019
(1) Molinia caerulea occurs in peatland vegetation communities. However, under certain environmental and management conditions it may overwhelm the typical peatland vegetation, compromising ecosystem services including carbon dioxide (CO2) sequestration ...
