For more than 20 million years, the ups and downs of diversity in terrestrial large mammals were determined by primary production, i.e. net
production of plant biomass.
«The total
amount of plant biomass will be much greater and far more diverse as we switch from making meat and cheese from livestock to plants.
He has been a member of various federal research panels, served on several editorial boards and advisory committees in microbiology, and helped author reports for DOE on solar energy generation and the
conversion of plant biomass into biofuels.
Conversion of natural vegetation to agriculture is a major source of CO2, not only due to
losses of plant biomass but also, increased decomposition of soil organic matter caused by disturbance and energy costs of various agricultural practices such as fertilization and irrigation.
«Each of these 10 genomes encodes for a unique composition of CAZymes — and the wider assortment helps formulate enzyme cocktails better suited for different
types of plant biomass to efficiently convert them into biofuels,» Grigoriev said.
Findings in the paper, «Worldwide Evidence of a Unimodal Relationship between Productivity and Plant Species Richness,» reveal a consistent biological rule governing the link between plant biomass and species richness in grassland ecosystems — plant species diversity is generally greatest at intermediate
levels of plant biomass.
«Consider the Neocallimastigomycetes — these fungi are one of the most powerful
degraders of plant biomass currently known and have a tremendous arsenal of plant cell wall degrading enzymes which may be useful for bioenergy production.
«Because big bluestem is currently a dominant grass species of the Great Plains and makes up to 70
percent of the plant biomass in places, how the ecosystem works could be affected by predicted changes in growth of this species,» Johnson said.
«Basically, we found that any driver of environmental change that will cause a loss of plant diversity will in turn reduce the stable production
of plant biomass through time,» Hautier said.
Cellulase denotes a family of enzymes primarily produced by bacteria, fungi, and protozoans that hydrolyze cellulose, a polysaccharide of -(1g4) linked glucose molecules that constitutes the principal structural molecule of plants and is the most abundant
component of plant biomass.
So if we have 100
pounds of plant biomass above ground, and an additional 100 pounds below ground, this still represents only 30 to 40 percent of this plant's total energy production.
For 20 Million Years, the Diversity of Large Terrestrial Mammals Depended on Plant Growth (15/09/2016) For more than 20 million years, the ups and downs of diversity in terrestrial large mammals were determined by primary production, i.e. net
production of plant biomass.
