• The multi-faceted role of algae in the Lake District aquatic ecosystem
• BSc Hons Biology

This project aimed to achieve a basic understanding of the microalgal ecology of the Lake District to lay a foundation for future studies. As such the work has been very exploratory. Regular sampling has produced a bank of nutrient profiles, preserved cells, and basic ecological profiles via microscopy. Additionally, samples have been sent for 16S and 18S sequencing, which appears to be the first ever look at
the microbial diversity through molecular techniques in the lakes. Attempts to isolate diazotrophs from the lakes have resulted in cultures at various stages of isolation, with an Anabaena culture partially established for future research in N-fixation and cyanobacterial physiology. Although this project did not follow the traditional hypothesis, test and record format, preliminary findings suggest that cell densities are in regular flux and varied assemblages are likely correlated with nutrients, although future molecular results will further our understanding.
