Abstract

Euglena gracilis, a unicellular microalgal species, play an integral role in marine ecosystems.
However, climate induced temperature change is expected to decrease the abundance of these
flagellated protists (Roleda et al, 2013). Here, we measured the growth rate of E. gracilis
following incubation in high temperature environments in order to mimic potential global
warming conditions. E. gracilis was grown for two weeks at incubation temperatures of 25oC,
30oC and 35oC (n = 3 for each treatment). The average growth rate of each sample was found to
be 0.00437 ± 0.00178, 0.00403 ± 0.00123, and 0.00337 ± 0.00173 %/hour respectively. A
one-way ANOVA analysis resulted in an F-value of 0.634 and a corresponding p-value of 0.563.
These results are statistically insignificant at α = 0.05 and suggest that elevated temperature up to
35oC does not affect the average growth rate of E. gracilis.
