... by biology and have the ability to rapidly convert CO 2 to biomass and vice versa. For instance, carboxylation is a critical reaction in primary production and metabolic pathways like photosynthesis in which sunlight provides energy to drive carbon fixation, whereas decarboxylation is a critical reaction...

... additional perturbations, these environmental disturbances led to a drastic decrease of the biomass of calcifying species and their biodiversity by ~80%, while the biodiversity of noncalcifying species was reduced by ~60%. We also suggest that the short-lived acidification caused by the Chicxulub impact...

...Ujjwal Layek; Siddhartha S. Manna; Prakash Karmakar Abstract Pollen loads of Apis mellifera were analysed to assess their daily pollen collection, polleniferous flora and their pollen biomass contribution in southern West Bengal, India. After that, the pollen host selection and pollen foraging...

The vegetation history indicates a change from open subalpine forests to closed western hemlock and Douglas fir forests as climate moved from cold and dry full glacial to warm and wet Holocene conditions. The fire history indicates that although there was more biomass burned in the Holocene, the frequency...

... ( Ishige et al., 2003 ). Additionally, the recycling of archaeal biomass by archaea themselves was suggested to minimize the energy cost of life in nutrient- and carbon-limited environments ( Takano et al., 2010 ). Here, we propose that the recycling of archaeal necromass into storage lipids like WEs...

Abundance counts may further understate the ecological importance of bivalves, which tend to have more biomass and higher metabolic rates than brachiopods. We evaluate...

... (∼8 to ∼7 Ma) might be due to a greater input of C3 terrestrial organic matter. The increase in δ 13 C SOM values at ∼7 Ma and the appearance of high δ 13 C SOM values ( c . −18.0 ‰) within Unit III-1 (∼7 to ∼2 Ma) indicate that C4 biomass overwhelmed the terrestrial catchment environment as a result...
