Common and Rare Freshwater Algae Comprehensive Identification Guide, Including Harmful Algal Blooms

About this book

Microscopic observations of the inhabitants in aquatic environments reveal the complex array of organisms that are woven together into a tapestry that is informative, ornate, colourful, and artistic. The diversity of life, especially among the photosynthetic organisms called algae, displays a unique suite of patterns and structures that allows the names to be assigned. This book compiles microphotographs from many groups and hundreds of genera to illustrate the beauty of algae and assist in their identification. The images in this guide were initially started as an academic, hands-on teaching guide rather than a digital version. This first edition organizes and arrays the images in taxonomic groups that can be used to instruct a new generation of phycologists, those that study algae. The identification and classification of algae from Linnaeus in 1767, through the 19th and 20th centuries, mostly relied on pen and ink line drawings, carefully constructed to illustrate morphological features that separated species, and these are still a valuable resource. Both scanning electron microscopy (SEM) and transmission electron microscopy (TEM) brought significantly higher resolution than light microscopy, illustrating the external and internal structures through black and white imagery. As digital photography improved for the light microscope in the past several years, colour images of the key features that distinguish one organism from another can now finally be generated.

Biography

Dr Barry H. Rosen has been studying algae for more than 50 years, beginning at the University of Connecticut. He is a world-class scholar and has taught algae workshops and courses around the country and online. His focus on cyanobacteria and harmful algal blooms has led to many invited speeches and media events. The advent of digital microscopic photography has allowed him to produce unique images of algae.
