Sampling issue stating most populations are not evenly distributed -
ANSWER>>spatial heterogeneity
Sampling issue stating populations change over time - ANSWER>>temporal
heterogeneity
, Sampling issue stating two random samples of the same populations migh t yield
slightly different results - ANSWER>>sampling variability
how do you avoid sampling issues? - ANSWER>>use standardized protocols
ensure techs understand protocol
use data sheets/tablets
use same techs

What is an experimental unit? - ANSWER>>the unit (e.g., individual animal,
vegetation plot), to which one application of a treatment is applied
what is sample size? - ANSWER>>the number of replicates or experimental units
in the study
why are controls necessary to consider in experimental design? -
ANSWER>>necessary to detect experimental changes
why is randomization important in experimental design? - ANSWER>>ensure
samples are not biased and protects against unrecognized influences
