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.

Characteristics of stem respiration in black spruce (Picea mariana) stand, interior Alaska

, 2021
Boreal forests account for roughly one third of the carbon sequestered in terrestrial ecosystems, and the high-latitude boreal ecosystem they make up has been consequently vulnerable to recent climate change.

Upregulation of MUC5AC by VEGF in human primary bronchial epithelial cells: implications for asthma

Respiratory Research, 2019
Background Airway mucus hypersecretion is an important pathophysiological feature in asthma. Mucins are glycoproteins that are mainly responsible for the viscoelastic property of mucus, and MUC5AC is a major mucin glycoprotein that is overproduced in ...

Respiration in the mesopelagic and bathypelagic zones of the oceans [PDF]

, 2005
This chapter reviews the mechanisms of transport and remineralization of organic matter in the dark water-columns and sediments of the oceans. Different approaches to estimating respiration rates are compared, and the discrepancies obtained by different ...

Respiration-induced modulation of global field power.

, 2021
(A) Exemplary schematic of our analysis approach showing the wavelet transform of time series data from each voxel. Global field power was computed on the time course of all 268 channels for further analyses of the MI and PTA.

Factors controlling spatio-temporal variation in carbon dioxide efflux from surface litter, roots, and soil organic matter at four rain forest sites in the eastern Amazon [PDF]

, 2007
This study explored biotic and abiotic causes for spatio-temporal variation in soil respiration from surface litter, roots, and soil organic matter over one year at four rain forest sites with different vegetation structures and soil types in the eastern

Zooplankton respiration

, 2007
This chapter reviews metazooplankton (>200 μm) respiration in aquatic systems. It discusses methodology, modifying agents (physical, chemical, and biological factors), definitions, and carbon equivalents. The major determinants of zooplankton respiration
