A.E. Walsby

Anthony E. Walsby, BSc(Birm), PhD(Lond), FRS, is the Emeritus Professor of Microbiology at the School of Biological Sciences, University of Bristol. He is a researcher in the fields of Algae, Cyanobacteria, Lake ecology, gas vesicles/vacuoles and genetics, covering the European lakes and Baltic Sea. [ [http://www.oceanexpert.net/viewMemberRecord.php?&memberID=4568 Ocean Expert] ] He is noted for his discovery of "Haloquadratum walsbyi" in brine ponds on the Sinai Peninsula in 1980.

Specifically his research includes:
*Gas vesicles of cyanobacteria: physiology; structure; molecular biology; ecology
*The natural selection of gas vesicles in relation to depth of lakes and oceans
*Population genetics of cyanobacteria using PCR on single filaments from lakes
*The cyanobacterium "Planktothrix rubescens" in stratified lakes
*Calculating the daily integrals of growth and photosynthesis in lakes
