EVS 463 Final

Mull

grasslands, deciduous woodlands with rich herb layer, and mediterranean scrub lands

moder

deciduous and coniferous woodlands with poor herb layer

mor

coniferous woodlands, Alpine meadows.

crypogamic crust

communities of living organisms on the surface of soils also known as bio crusts

catabolism

breaking down and transformation of energy

labile

capable of being digested, absorbed to the benefit of the organisms, nitrogen is only usable if fixed → bioavailability.

basidiomycetes

important decomposers, ECM, club fungi. has fruiting bodies → mushrooms

ascomycetes

sac fungi, common in soil and aquatic habitats, cup shaped

Arbuscular mycorrhizal fungi (AMF)

forms structures inside of root cells and extends thin filamentous hyphae far into the soil, obligate mutualists

ectomycorrhizal fungi

primarily associated with trees and form sheath around root cells

what group is the flagellate in?

euglena

what group is cilliates in?

paramecia

which decomposers have the greatest importance, presence, abd biomass in alpine or polar tundras?

microfauna

what is the group name of amoeba?

protista

Gaia hypothesis

Proposes that the Earth and its biological systems behave as a single, self-regulating entity, maintaining conditions for life.

what role does soil play in C sequestration?

soils are likely the last great frontier in study of carbon sequestration and cycling. Soil serves as a major carbon reservoir, influencing both the storage and release of carbon through organic matter decomposition and microbial activity.

why is soil biodiversity best considered by functional groups?

there can be so many different species in just one functional group that the individual type of species does not matter as much as the function they provide matters.
