Periphyton dynamics in laboratory streams: a simulation model and its implications. Poclostemum ceratophyllum was the primary producer component of the community and also provided a place of attachment and shelter Monogr. Although nutrient status can significantly modify rates, the ultimate driver of aquatic primary production is light availability. 35:866–870. Barsdate, R. J., R. T. Prentki and T. Fenchel. 1978.

VanWinkle. integrated primary production during leg 2 was attributed to mixing-induced nutrient injection and redistribution of chlorophyll in the photic zone. Waldo Lake, Oregon. Primary productivity is the rate at which energy is converted by photosynthetic and chemosynthetic autotrophs to organic substances. Can. 40:569–671. Hydrobiologia 69:251–259.

Granhall, U. Freshwat. Limnol. Primary Production • Gross primary production is the total elaboration of organic matter through photosynthesis (GPP) • Autotrophic respiration is the metabolism of organic matter by plants • Heterotrophic respiration is the metabolism of organic matter by bacteria, fungi, and animals DePinto, J.

The purpose of this study was to examine the primary production rates of phytolithic communities found in the major different habitats of streams and determine the effects of physical and chemical parameters associated with each habitat on periphyton community spatial structure.
