A macroinvertebrate multi-metric index for Ethiopian highland streams Article (PDF Available) in Hydrobiologia August with Reads How we measure 'reads'. Headwater streams in the highland regions of Ethiopia are exposed to severe human disturbances because of rapid population growth. Protection and management of headwater streams require the development of informative indices that can capture disturbance and assess streams water quality in highland regions. Therefore, we developed a multi-metric index based on macroinvertebrate Author: Temesgen Alemneh, Temesgen Alemneh, Argaw Ambelu, Benjamin F. Zaitchik, Simon Bahrndorff, Seid Tiku. Multi-metric index development for biological monitoring in Washington State streams / Caption title. "June " Includes bibliographical references (p. ). Also available on the Internet. Contributor: Wiseman, Chad D. Date: The multi-metric index concept has proven to be very adaptable (Karr and Chu ), and many of the same metrics have been used successfully throughout different regions of the world in a variety of stream types (Simon and Lyons ). Metrics such as species richness (the total number of taxa) or the EPT approach (number or individuals or Cited by: 2.
Biological monitoring, especially multimetric approaches such as the index of biological integrity, acknowledges the importance of rivers' biotic integrity and offers one of the strongest. monitoring instream conditions using a multi-metric habitat index. We have developed and applied a method for rating disturbance in wadeable streams throughout Illinois and collected information on physical habitat at sites statewide. Index development and outreach will be the focus of our efforts for the remainder of the project. (Essay) Measuring Biological Condition, Protecting Biological Integrity. By James R. Karr, University of Washington, Seattle. Environmental change has always been a reality, and it is continuous. Change on our planet is driven by wind and water, geological activity, astronomical events, and the work of microorganisms, plants, and animals.

1. Introduction. Robust and reliable tools are required for the measurement of ecological integrity (Karr and Dudley, ).One of the most widely used assessment tools in North America is the multi-metric index (MMI), sometimes called an index of biological integrity or IBI, which is used by over 90% of US state water resource agencies (Barbour and Yoder, ).Author: Matthew T. Bolding, Adam J. Kraft, Derek T. Robinson, Rebecca C. Rooney. An Ecological Integrity Assessment (EIA) is an approach to systematically rate the current ecological integrity of an occurrence of a plant association or ecological systems. The goal of an EIA is to provide a succinct assessment of the current status of the composition, structure, processes, and connectivity of a particular occurrence of an ecosystem type, interpreted in light of reference.

An Index of Biological Integrity (IBI) is a synthesis of diverse biological information which numerically depicts associations between human influence and biological attributes. It is composed of several biological attributes or 'metrics' that are sensitive to changes in .
