85. Untitled Document online journals on the transitional water ecology conservation and management (ie, Transitional Water Bulletin and Transitional Water Monographs). http://www.dsa.unipr.it/SITE/documenti/twreferencenet.htm

Dear All, TWReferenceNET, which is a INTERREG III B CADSES project promoting conservation of river mouth ecosystems, lagoons and coastal wetlands, is launching a Newsletter, entitled Transitional Water Bulletin in the CADSES area, on these topic. The Newsletter will be issued bimonthly. The Newsletter is part of a larger Editorial project, which will lead in the next few months to the launch of two new international online journals on the transitional water ecology conservation and management (i.e., Transitional Water Bulletin and Transitional Water Monographs). The Newsletter is a major way to disseminate results and deliverables of TWREferenceNET as well as of all the projects funded by INTERREG III B CADSES and dealing with river mouth ecosystems, lagoons and coastal lakes; its is an opportunity to start or strenghten the collaboration among different project groups working inside INTERREG IIIB framework under related topics. In addition, the Newsletter wants to be an open space of information and discussion on most of the major topics, events, achievements, proposals, regarding ecological health status, conservation and management of the transitional aquatic ecosystems in the Mediterranean area. News on scientific discoveries, natural and cultural heritage beautie, conservation and management strategies, anthropic pressures and particular local or global scale problems affecting transitional waters as well as announcements of meetings and events can be found in the newsletter.

NSERC Industry Research Chair Program Water and Watershed Research Clean fresh water for drinking is a basic need for human life, society and the economy. Ecosystems and watersheds supplying drinking water are subject to variable degrees of human-generated pressures associated with population growth and there is an ever increasing demand for high quality drinking water. Understanding the abilities and limits of ecosystems to sustain clean water under continuous human interventions is a central issue to society and a challenge for ecologists and environmental scientists. Our goal is to provide limnological and ecological expertise and information to water utilities in order that they can make environmentally sound ma nagement decisions to preserve the quality of their source water. The first major focus of our research is on the environmental management of drinking water, which is funded as an NSERC-Industry Research Chair Award. This is a partnership research program with funding from NSERC, water utilities, industries, government departments and local communities. The major objective of our

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.).

The Ecology Centre was established in 1991 as a result of sponsorship from the Northumbrian Water Group The Ecology Centre The Centre's Director is Professor Wallace Arthur. The Centre provides a resource base for students taking courses with an ecological component. It includes a seminar room, computer room, meetings room and library. The Centre also acts as a base for research projects in ecology and related areas of biological science. Staff associated with the centre are active in a wide range of fields. A central theme both in the Ecology Centre and in the Environment division of Northumbrian Water is biodiversity : its origins, evaluation and conservation. We are also aligned with EntecUK , one of the UK's largest environmental and engineering consultancies.
