- Zygnemataceae abstract "The Zygnematacae are a family of filamentous or unicellular, uniseriate (unbranched) green algae. The filaments are septated and reproduction is by conjugation; Spirogyra is commonly used in schools to demonstrate this kind of reproduction. The family is notable for its diversely shaped chloroplasts, such as stellate in Zygnema, helical in Spirogyra, and flat in Mougeotia. The Zygnemataceae are cosmopolitan, but though all generally occur in the same types of habitats, Mougeotia, Spirogyra, and Zygnema are by far the most common; in one study across North America (McCourt et al., 1986, as reported in Wehr, 2003, pg. 363), 95% of the Zygnemataceae collected were in these three genera. Classification and identification is primarily by the morphology of the conjugation, which is somewhat rare to find in natural populations of permanent water bodies; when in the vegetative state, the rarer genera resemble the three most common, and are often mistaken for them and catalogued as such. Conjugation can be induced in low-nitrogen culture.While they occupy many habitats, in North America all are found solely in freshwater or subaerial habitats. Species typically exist as floating mats in stagnant water in ditches and ponds, but some also grow in moving water, attaching themselves to a substrate by rhizoid-like projections of the basal cells of the filament. The mat species rise to the surface in early spring, grow rapidly through the summer, disappearing by late summer. Several genera appear to be endemic: Entransia is unique to Nova Scotia, and Pleurodiscus to Puerto Rico; Mougeotiopsis is known only from Michigan, Wisconsin, North Carolina and British Columbia. Zygogonium and the unicellular Zygnemataceae prefer acidic water, and Ancylonema and one species of Mesotaenium grow on glacial ice. Members of the Zygnemataceae, such as Spirogyra, fall prey to parasites, especially chytrids.".
