Integrating Principles and Concepts from General Ecology, Stream Biology, Biological Diversity of Stream Invertebrates, and Water Chemistry,Robert Bohanan, UW Center for Biology Education Stanley Dodson, UW Zoology Dolly Ledin, UW Center for Biology Education Kris Stepenuck, UW Extension & WI DNR Jongdee To-im, Visiting Scholar from Thailand,化妆品 ,Goals & Objectives,Enhance the ability of leaders of stream and river monitoring programs to provide effective education and training of participants in their programs that result in data that are relevant and useful Help citizens understand the complex nature of aquatic systems and thereby increase their ability to make informed decisions about water Create resources that are specific to Wisconsin streams & rivers,Definition of Ecology,Ecology is the study of how biotic and abiotic factors influence the distribution and relative abundance of organisms in ecological systems. Limnology is concerned with all the interrelated factors that influence the water environment.,Units of Study or Investigation,Individual organism Population of a species of an organism in an area Community or groups of populations of several species in an area Ecosystems include communities and abiotic factors Landscapes can be thought of as a geographic region that typically includes several ecosystems Biosphere or global ecological systems,Introductions,Number of years that youve been involved in water research, education, training, and / or monitoring 0-5 6-10 11-15 16-20 20+ Your favorite order of aquatic insect,Overarching Concept,Ecology is the study of how living (Biotic) and non-living (Abiotic) factors influence Living Systems Living Systems include: Individual organisms Groups of organisms,What types of factor influence biological diversity in rivers and streams?,Abiotic factors,Biotic factors,Biological Diversity,Thought Questions,1) List examples of biotic factors that are influenced by abiotic factors. 2) List examples of abiotic factors that are influenced by biotic factors. 3) How do biotic and abiotic factors influence biological diversity independently? 4) How do biotic and abiotic factors act in concert to influence biological diversity?,Light,Current,Substrate,Temperature,Chemical Factors,Producers,Consumers,Predation,Competition,Invasive Organisms,Biological Diversity,Light,Current,Substrate,Temperature,Chemical Factors,Producers,Consumers,Predation,Competition,Invasive Organisms,Biological Diversity,Physical Environment,Chemical Environment,Biological Environment,Stream order determination,Use what youve learned about how to classify streams by stream order and for each of the streams on the hypothetical stream network determine stream order.,Stream order determination,Use what youve learned about how to classify streams by stream order and for each of the streams on the hypothetical stream network determine stream order.,1,1,1,1,1,1,1,2,2,2,3,3,3,Thought Questions,1) How would water temperature change as you move from streams of a lower order to streams of a higher order in a stream system? 2)How would you expect the types of predators (e.g. species or groups) to change as you move from lower order streams to higher order streams in a stream system? 3)Think about a stream that youre familiar with its watershed. Determine the stream order. Based on the stream order and using the river continuum concept, determine and describe how the physical and biological characteristics of the stream match what the river continuum concept would predict.,Stream Order,Organic Energy Sources,Ecological Communities,Channel Width,Diagram courtesy of Riveredge Nature Center,Figure 7.
