applied ecology Flashcards
applied ecology
applitcation of concepts and science of ecology to real world
- management of ecosystems
- use observation experimetns and modelling for studies
examples of applications
agro-ecosystem mngmnt biodiversity conservation ecosystem restauration environ. engen. ivansive species mngmnt wildelife mngmnt
why manage ecosystems
wwe strongly depend on them
blue and green water
blue -> accessible water
surface runoff
green -> water in atmosphere, stored in plants ect
transpi or evaporation?
trees are major compenent in water transevop…
case study water loss trees
two connected needles in the tree
one heated other not
on day:
heatet needle cooled down by water flow -> low difference in temp
in night:
no water flow -> high temp difference in temp
if compared -> measure of water flow that is transpired
how much does a forest consume (water)
up to 75% of precipitation
forest influence on water flow
when forest -> much water is transpired and does not go into the river.
without forests -> more water gets into rivers
no transpiration -> no rain over forest -> water goes into the ocean
australia forest fires
trees are adapted -> big trunks that down burn
increasing rate -> temperature elevation
much more hot days per year
big trunks that dont burn
FACHBEGRIFF
LIGNOTUBER
store water and carbohydrates -> access when burned
simulation without fire vs with fire
fire off -> more trees -> closed forests could double
especially humid grasslands and savannas have potential to form forest -> but there are most fires
influence of fires on water
more water needed from young trees -> less runoff -> more green water and less blue water
reverse pattern of before!
dont always believe text book
population in australia grows and water availability shrinks
solve water problem autralia??
build forest retail zones with big reservoirs
desaltination plants:
starts running when drought
608milion $ a year
what do simulation for future tell aboud water suplly in australia
high demand and high climate change: not enough in 2028 medium - medium: not enough until 2043 low-low: until beyond 2065
action plan of melbourne?
NO NATURAL MEASURES
