1
Q
methods of plant sampling
A
point quadrat
frame quadrat
2
Q
how to measure plant species richness and evenness
A
density of plant pop - count in one quadrat then times
frequency of plant pop- count no. of squares containing plant pop and find % of squares with them in
percentage cover of plant pop
3
Q
how to measure animal species richness and evenness
A
capture mark release recapture
more marked when recaptured means smaller pop.
ratio between no. of each is evenness
4
Q
what are some abiotic factors
A
wind speed light intensity relative humidity pH Temp O2
5
Q
how tech. helps when measuring abiotic factors
A
precision with sensors
reduce human errors
react to rapid changes across sampling points
data stored and tracked
6
Q

A
pooter sweep nets pitfall traps tree beating kick sampling - river bank and hold net downstream
