How is the distribution of a species where it lives shown
on a map
What are the two main abiotic varibales that affect animal dsitribution
water availaibility and temperature
What are plant distirbutions affected by
temperature, water availability, light intensity, soil pH, soil salinity, availability of nutrients
What is the range of tolerance
indicates the maximum and minimum limits of abiotic variables that the organism can withstand
How do we investigate the range of tolerance
the use of a transect (belt/line)
How does a line transect work
organisms found at the regular ample points are recorded
How does a belt transect work
quadrats are placed at regular sample points and the abundance of organisms within each is recorded
