Euglenastic Temperature: Euglenae Reproduction Rate in Different Temperatures Kevin Fan and John Yin Moscrop Secondary Floor Location : J 93 L

Complications on planet Earth are having negative effects on animals, especially the producers, for example, algae. Without producers, other species will become endangered or extinct. One of the simplest of these producers is the Euglena, a type of photosynthetic protist. Photosynthetic microorganisms play an important role in the carbon cycle and in aquatic food chains, but with global warming going on, the food chain might collapse because it is eliminating amounts of these microorganisms. Finding a way to see if these global problems can endanger Euglenae will be very useful.

To determine if Euglenae can survive the global problems, three different environments were set up. The number of Euglenae was counted every day for five consecutive days in order to determine their rate of reproduction in the three different temperatures.

The results showed that Euglenae in the coldest temperature setting reproduced the most, while those in the highest temperature setting reproduced the least. In conclusion, our data suggests that global warming is having an effect on Euglenae because heat counts down the reproduction rate.
