METABOLISM CHARACTERISTICS OF SEAGRASS HALOPHILA SPINULOSA: CARBON DIOXIDE ABSORPTION RATE IN PHOTOSYNTHESIS AND OXYGEN USE IN RESPIRATION

open access: yesJurnal Ilmu Kelautan Spermonde, 2023
One of the roles of seagrass is as a carbon sink so its presence in the waters is very important. Each species of seagrass has a different character related to photosynthesis and respiration.

Behaviour of carbon dioxide and water vapour flux densities from a disturbed raised peat bog [PDF]

open access: yes, 2002
Measurements of carbon dioxide and water vapour flux densities were carried out for a disturbed raised peat bog in the north of the Netherlands during an 18 month continuous experiment. Tussock grass (sp. Molinea caerulae) mainly dominated the vegetation
