Using high quality PHOTOGRAPHS of BLUE-GREEN ALGAE, this atlas of CYANOBACTERIA endeavors to illustrate the diversity of CYANOBACTERIA (BLUE-GREEN ALGAE) in New England.

The ILLUSTRATIONS include IMAGES of HAB (harmful algal blooms) such as APHANIZOMENON, MICROCYSTIS, PLANKTOTHRIX, WORONICHINIA, GLOEOTRICHIA, DOLICHOSPERMUM, MERISMOPEDIA, ANABAENA, ARTHROSPIRA, SPIRULINA, and other plankton in our waters. There are also PHOTOS of commonly encountered CHROOCOCCUS, GLOEOCAPSA, MICROCOLEUS, NOSTOC, OSCILLATORIA, PHORMIDIUM, SCYTONEMA, STIGONEMA, TOLYPOTHRIX which may aid in the identification of these organisms.

Another purpose of this searchable collection of cyanobacteria is to illustrate some of the complexities in IDENTIFYING these enigmatic organisms. The IMAGES show the blue-green algae in their “normal” textbook forms but also in their aberrations and how they routinely morph into other “species” when the conditions of their environment are less than ideal.

      Boring But Important

      Cyanobacterial taxonomy is notoriously complex...and imprecise. Ideally we would like a simple and clear dichotomous key that would consistently and reliably lead us to a consistent conclusion. Unfortunately, the paucity of distinctive phenotypic characters in even these most complex of bacteria renders that ideal impossible.

      This is not the place to discuss the complexities of cyanobacterial genetics and speciation, however I will admit to the tyro cyano taxonomists of the world that even professionals have trouble with the overlapping of species descriptions in the few keys available. Furthermore, all the foundational keys and descriptions are European in orientation and the general consensus is that only 10%-15% of cyanobacterial species may be cosmopolitan. With that in mind I have generally only included genera and species which have enough distinctive characteristics as to be confidently named.

      I tend to bypass many of the unicellular forms and the Leptolyngbyas etc. as being too difficult to be confident of my determinations. Generally I include several photos for each organism to show what you will see through your scope. I try to illustrate the important diacritical features but balance this with just trying to illustrate the true beauty of the blue-greens.

      Remember! You cannot identify a cyanobacterium via a photograph! All names have been thoroughly researched in numerous texts and journals and I believe them to be correct—phenotypically and ecologically, if not genetically. If you do spot a mistake, have comments or suggestions, or have an interesting little blue-green you’d like to put a name to, kindly contact me. I WILL respond.

      Finally, this atlas is an ongoing project and will grow and change over time. So tune in again. Thank you.

      Locations

      Common in this document has two meanings. For locations in New England (including NY), “common” is used to designate species frequently found in a variety of habitats throughout the region. Dr. Robin Matthews’ locations from WA use “common” to designate those species found at that location on multiple dates and in abundance within the sample. Also, locations from an "IWS water quality monitoring site" may be referenced in more detail at https://www.wwu.edu/iws (follow the links to Northwest Lake Monitoring).
