摘要

Pithophora oedogonia is a green, filamentous alga. It is a free floating organism forming thick, heavy mats of vegetation that can fill in small impoundments. It is generally a serious management problem because of its apparent resistance to standard algicides. In Indiana the alga overwinters as vegetative filaments and akinetes (nonsexual, thick-walled spores). Akinetes comprise approximately 21% of the overwintering free-floating biomass. Akinetes and overwintering filaments germinate to produce new vegetative filaments in the spring in response to an increase in water temperatures and a replenishment of nutrients. Net photosynthesis increases from a low in midwinter to a high in mid June and July.
