I will look at how algae have been used to indicate both past and present climate changes. Algae as indicators of environmental change Example 1: Nearshore, attached. They have been used to study sea level change, climate variability, floods and tsunamis, problems associated with changes in salinity and nutrients due to human activities, and to assess ecosystem responses to remediation, among others. (1994) Algae as Indicators of Environmental Change. Algae have long been used to assess environmental conditions in aquatic habitats throughout the world. Perspectives on the Use of Algae as Biological Indicators for Monitoring and Protecting Aquatic Environments, with Special Reference to Malaysian Freshwater Ecosystems McCormick, P.V. Differences between algae and terrestrial plant feedstocks, as well as their supply chains for biofuel, influence the choice of appropriate sustainability indicators ().Algal biofuel production interacts with aspects of the environment across the entire supply chain (), Algal biofuel supply chains differ somewhat from other bioenergy supply chains. Journal of Applied Phycology, 6, 509-526. - Lichens, Plant indicators. By Frank Otto. 25 - Diatoms as indicators of environmental change in wetlands and peatlands from Part V - Other applications By Evelyn Gaiser , Florida International University, Kathleen Rühland , Queen's University E.g. Second, I will look at how algae (both micro and macro) have been used as indicators of climate change by looking at specific research that has been done. The key to effectively measuring damagingly high levels of nutrients in freshwater streams lies in the microscopic organisms living in them, according to a group of Drexel University scientists. Diatoms are valuable paleo-indicators of natural processes and environmental changes caused by human activities in estuaries. - Animals, Plant indicators. Environmental bioindicator Biodiversity bioindicator Ecological bioindicator Detects the presence of pollutants. and Cairns, J. During the early part of the twentieth century, algae were exploxed as indicators of organic pollution in European streams and rivers (Kolkwitz and Marsson, 1908). Douglas and J.P. Smol (eds), 2004. Detects the change in natural surroundings and their impacts. October 26, 2016 Christine Sellers Education, Environmental Science, Featured, Ichthyology, People, Photoblog. Between 20 …

This essay will approach the subject in a two fold manner: First I will seek to explore why algae would be used as indicators of climate change. We attribute this situation both to an underappreciation of the utility of algal indicators among non-phycologists and to a lack of standardized methods for monitoring with algae. Key words: Algae, Diatoms, Chrysophytes, Cyanoprokaryotes/Cyanobacteria, Climate change, Environmental change, Arctic, Antarctica, Paleolimnology, Lakes, Ponds 117 R. Pienitz, M.S.V. Diatoms as indicators of environmental change in Antarctic and subantarctic freshwaters SARAH A. SPAULDING, BART VAN DE VUVER, DOMINIC A. HODGSON, DIANE M. MCKNIGHT, ELIE VERLEYEN, AND LEE STANISH 14.1 Introduction occurring as individuals, small colonies, or as cyanobacterial The polar regions, both Arctic and Antarctic, show strong evi­ dence of climate change … Algae are widely distributed in the aquatic environment. and Cairns, J.

Biological indicators like algae have only recently been included in water quality assessments in some areas of Malaysia. Long-Term Environmental Change in Arctic and Antarctic Lakes. The use of algal parameters in identifying various types of water degradation is essential and complementary to other environmental indicators. Detects changes in the biodiversity and the species present in it. E.g. Diatoms as indicators of environmental change in shallow lakes 157 can compensate for some of the mixing problems and can potentially allow for high resolution studies. E.g. Algae are an ecologically important group in most aquatic ecosystems but are often ignored as indicators of aquatic ecosystem change. Example 2: Algae in lake. Diatoms as Indicators. Algae are important indicators of environment situation since they respond immediately to both qualitative and quantitative composition of species in a wide range of water situations due to alters in water chemistry such as increases in water pollution based on domestic/industrial wastes and affect the composition of genera that are able to tolerate these situations. In the analyzed algae from the Black Sea, metals like cadmium, iron, zinc, copper, lead, and thallium were present. (1994) Algae as Indicators of Environmental Change. From all of the analyzed elements in the algae, iron was present at the highest concentrations. Kluwer Academic Publishers, Dordrecht, The Netherlands.
