How Our Systems Work Together

Ved Khaliq Eshal

Eggs are a rich source of protein,which has many uses in food preparation.Prepare a nutritious and interesting one-dish meal with the use of eggs for a group of people

ocean circulation patterns

cold ocean temperatures

atmospheric high pressure

dead trees/logs (auotgenic engineers) environment for nitrifixation, animals, and microbes.

birds (Pileated Woodpecker)

Sometimes causes decay on upper trunk

control insect infestations

saproxylic insects

insect infestations, herbivores

makes cavaties for birds

microlitter,CWD, litterfall

decomposition of organic material

allogenic engineers (possibly aid in regeneration of plants)

soil protozoa, invertebrates, fauna

NH3

reduce fungi favoring bacteria

saprophages (bacteria, fungi, macroinvertebrates)

immobilize, mineralize nutrients (nutrient conservation)

transfers nutrients from soil to litter through hyphae

chelators (increase solubility of nutrients)

nitrogen-fixation

Endangered species

Spotted Owl

Marbled Murrelet

animals/insects (disperse fungi and seeds)

cerambycid beetle

chickaree

canopy drip

Disturbances

logging

possible old-growth recovery over time

monoculture sites drains nutrients and soil organisms from soil

causes invasive species because of excess solar radiation

compacting soil (which negeatively effects plants because less oxygen and water. With less vegetation there is more solar radiation and denitrifiers prosper, taking the nitrogen out of the soil), damage aquatic sites,

global warming

increase in temperature, less fog, moisture, and possible drought which leads to insufficient nutrients, and less primary productivity.

fires

It can also cause loss of nutrients through heat and fly ash.

controls pests

minerals from leaching

Coast redwood has high resistance and fire thins understory allowing more nutrient availability for the old-growth trees (reduces competition and monitors invasive species).

floods

soil minerals

erosion/landslides

change aquatic sites, causes silt to alter fish habitats, loss of steep banks

colluvial and alluvial sites

soil compostion (nutrients)

pH

Diversity in plants (Keeps soil nutrient rich and promotes soil organisms)

lower nutrient

Pigmy forest-provides a range of habitats through this ecotone

plants

moisture

regeneration

nutrients, water, sunlight

wood rats strip bark off new trees

foliar uptake (80% redwood forest species)

Coastal Fog

Decrease temperature, increase humidity, reduce solar radiation (prevents denitrification)

Douglas fir

fisher

marten

voles

OLD-GROWTH COAST REDWOOD

Lichen (alga and fungus-rock weathering for soil) (endophytes inhibit plant pathogens)

tree crown (nutrients from air through epiphytes)

coastal fog reduces transpiration, which keeps stomata open, allowing for more carbon dioxide intake.

photosynthesis

Oxygen

roots/exudates

hyphae from mycorrhizal fungus

rizosphere (good in droughts): organic acids, enzymes, amino acids, proteins, simple sugars, carbon

Mycorrhizal Network (connects fungus, bacteria, and roots from plants and trees. Keystone for redwood forest.)

nitrification (nitrate) ammonia

plant hormones

nutrient transfer (especailly phosphorus)

indirectly water transfer for photosynthesis

mycorrhizal propagules

mammals

carbohydrates

carbon
