species diversity
dominance
stratification
species diversity depends on
type of area- lattitude ,altitude
climate-temp[most imp], rainfall [2ndmost], light
type of soil
size of area more -species diversity more
dominance eg.
prosopis in aravali hills
pinus in himalaya
stratification- forest [basis is light]
max str/clear str - tropicla f
lake stratification
- basis light
littoral zone [ecotone/ max divrsity p/r=1
limnetic zone [open h2o/ euphotic p/r>1
profundal zone [deep dark/aphotic/max heterotrops p/r<1
benthic zone[ disphotic/ submerged rooted]
basis temp-
epilimnion
metalimnion
hypolimnion
succession- biotic comm. r never stable
pioneer comm.-1st comm. to inhabit a area ||| growth rate more, r selected species
climax comm. -is nearly in eq with environment |||growth rate less, s selected species
seral comm. -comm. that come bet both
sere- the entire sequence of comm. that succ change in a given area
sere
pioneer +seral+ climax
