Daniel McAree David Lutz Davis Thomas BS 158H 10/13/10 The Effect of Temperature on Algal Growth Benthic algae plays an essential role in aquatic ecosystems because it is a source of food and habitat for many aquatic organisms (Sterner and Grover 1998). Benthic algae are primary producers, and temperature is an important factor regulating algal biomass (White et al. 1991). Temperature increases potentially harmful algal blooms if it gets too hot, which is significant to us because temperature is increasing with climate change. Lower temperatures may inhibit the effect of nutrient levels by decreasing the activity of enzymes, which reduces the catalytic power of nutrients in the enzyme (Flanagan et al. 2003). Therefore, temperature increase should improve enzymatic activity, resulting in more productivity in algal growth. Temperature projections from the Intergovernmental Panel for Climate Change predict that the average annual global temperature will increase by 2°C by 2050 and another 4°C by 2090 (Temperature Projections - IPCC).

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
