Water Plants 101 A basic Introduction to the physiology and ecology of aquatic plants By Dave Huebert Carbon Dioxide The low diffusivity of CO2 in water, the relatively thick unstirred layer and the high CO2 concentration needed to saturate photosynthesis have prompted one scientist to state, "For freshwater submerged aquatic macrophyte plants, the naturally occurring DIC levels impose a major limitation on photosynthesis ... The DIC limitations on aquatic macrophytes and its corollary, the need to conserve carbon, are becoming increasingly apparent as important ecological features of aquatic environments (George Bowes, 'Inorganic Carbon Uptake by Aquatic Photosynthetic Organisms, 1985)." Aquatic plants have adapted to CO2 limitation in several ways. They have thin, often dissected leaves. This increases the surface to volume ratio and decreases the thickness of the unstirred layer. They have extensive air channels, called aerenchyma, that allow gases to move freely throughout the plants. This allows respired CO2 to be trapped inside the plant and in some species even allows CO2 from the sediment to diffuse into the leaves. Finally, many species of aquatic plants are able to photosynthesize using bicarbonate as well as CO2. This is important, since at pH values between 6.4 and 10.4 the majority of DIC in freshwater exists in the form of bicarbonate. For the aquarist, the supply of CO2 can be augmented in two ways. Both methods work by increasing the rate of diffusion of CO2 into the plants. First, the rate of water movement in the aquarium can be increased. This will decrease the thickness of the boundary layer and ensure that CO2 levels are at air equilibrium. This method is inexpensive, easy to implement and will produce excellent growth of aquatic plants under most conditions. Secondly, CO2 can be injected into the aquarium. This method can be expensive, and if done improperly, can be lethal to fish. This latter method is only essential, however, if there is a significant daily pH fluctuation in the aquarium, or if the species of plants being cultured are completely unable to use bicarbonate (such as Cabomba sp.).

Central Pacific Island Environments Hawai`i Coral Reef Bibliography INTRODUCTION HOW TO ACCESS DATA FIELDS IN HCRB SEARCHING THE DATABASE IN EndNote REVISING THE DATABASE EndNote Officially entitled "Inventory Catalogue of Hawai`i's Coral Reefs" the Hawaii Coral Reef Initiative Computer Interactive Bibliography (HCRIB) is a project of the Hawai`i Wildlife Fund (Principal Investigators, Carl J. Berg and Hannah J. Barnard) in collaboration with AECOS , Inc. (Eric B. Guinther, Joann Fisher, and Hilary Maybaum). This project has been supported by a grant from NOAA / U. S. Coral Reef Initiative The HCRIB is an EndNote Plus bibliographic reference data base which provides reference listings of surveys, studies, technical reports, atlases, and the like on subjects ranging from physical oceanography, biology, taxonomy, water quality, ecology, and reef resources for the main Hawaiian Islands. In gathering references for inclusion, the editors have placed particular emphasis on technical reports (essentially unpublished reports) by corporations, consultants, students, organizations, and government agencies for the reason that these types of studies and surveys are most difficult to track through standard bibliographic data bases. Also, far greater numbers of field surveys and site specific observations are available from this "gray" literature than anywhere else. References listed in this database are limited to marine environments found around the main Hawaiian Islands from the shore out to a depth of about 60 feet. A similar data base for Hawai`i fresh and brackish waters is under development (see
