Dataset from the MICROCODE project

Data on the in vitro growth of mock populations of Metschikowia reukaufii (Ascomycota) in different treatments. The dataset contains five columns:

Population: name of the mock population (FP1, FP2, or FP3).

Step: propagation step (T1 to T32).

Treatment: SBE, stable benign environment (the mock communities were propagated every 3 days in a benign nectar for the whole duration of the experiment); SRE, stable restrictive environment (the mock communities were propagated every 3 days in a restrictive nectar for the whole duration of the experiment); PFE1, predictably fluctuating environment #1 (the mock communities were first inoculated into a benign nectar and, after 3 days, an aliquot of the communities was transferred to a restrictive nectar; this transfer of the evolved communities from a benign to a restrictive nectar and vice versa was repeated every 3 days); PFE2, predictably fluctuating environment #2 (this treatment is equivalent to PFE1, but the inoculation order was reversed; i.e., the mock communities were first inoculated in the restrictive nectar, then in the benign nectar, and so on); RFE, randomly fluctuating environment (in this case, the type of nectar -benign or restrictive- that was inoculated with the mock communities was randomly chosen at each propagation step).

Nectar: BN, benign nectar (artificial nectar containing a moderate amount of sugars and high level of nitrogen); RN, restrictive nectar (artificial nectar of high osmolarity and containing a very limited amount of nitrogen).

CFU_count: colony forming units (CFU) per mL.
