Habitat Preference in Artemia franciscana
Artemia franciscana (brine shrimp) inhabit saline lakes and temporary
ponds. Nauplii larvae hatch from resting eggs in the spring. The
response of a mobile animal, such as Artemia, to variation in a single
environmental factor is often investigated through the use of a habitat preference
experiment. In this experiment, Artemia will be exposed to wide
range of habitats or intensities of a single factor (e.g. temperature, light,
pH), given sufficient time to select a given habitat, and then sampled to determine
the preferred condition. The experiment will attempt to answer if Artemia is
indifferent to the factor under study or does it actively select a specific
condition and what is the preferred condition. This exercise is used
to re-enforce hypothesis testing and the use of chi square goodness of fit
statistical test.
