The Inorganic Carbon Complex: Alkalinity, Acidity, CO2, pH, Total Inorganic Carbon, Hardness, Alumiweak, carbonic acid solution that can change the pH of the water and dissolve minerals, which in turn can increase alkalinity and impart hardness to the water. The amount of dissolved salts in water is of major importance to the maintenance of life and in the treatment of water for domestic and indu

AMITY

Organic Matter,bon in natural waters is in the form of dissolved organic carbon (DOC), colloidal organic carbon (COC), and dead particulate organic carbon (POC). This quantity of detrital (nonliving) organic carbon greatly exceeds that amount of carbon in all of the living biota combined. A ratio of ca. 10:1 for D

Benthic Fauna of Lakes,minant energy sources for the benthic fauna. Consequently, a variety of types of feeding and of reproductive dynamics occur among the benthic fauna. It is, therefore, essential in limnological analyses to obtain reliable quantitative estimates of the sizes and distributions of populations constituti

Primary Productivity of Phytoplankton,sal mechanisms regulating the synthesis, utilization, and loss of the organic matter..The complex biochemical reactions of photosynthesis can be summarized by the general redox reaction: ..Cyanobacteria, prochlorophytes, eukaryotic algae, and higher plants use light energy to oxidize water to molecu

Feeding Rates by Protists and Larger Zooplankton,nit time (hour or day). This term, usually synonymous with filtration capacity, should not imply, however, that the volume of water passed over the filtration appendages is known, that all particles of a given type have been removed from the water, or that all particles retained by the filtration ap

RECUR

Zooplankton Production,ingestion and egestion (.).With continuous reproduction, the cohorts of the population overlap, so that it is either difficult or impossible to observe changes in abundance over time. To analyze the production of populations with continuous reproduction, it is necessary to use methods that do not re

Predator-Prey Interactions,.In evaluating predator-prey interactions, both the predators and prey have physiological and behavioral characteristics that must be considered. Major . characteristics that can be evaluated include: (1) visual, mechanical, or chemical detection of prey; (2) how much energy is required during searc
