Application of Ecological Indicators

TLDR

Ecological indicators, widely used by scientists, managers, and the public, have evolved over the past 40 years to assess environmental condition, warn of ecological problems, track resource trends, and are mandated legislatively in many countries. The study aims to enhance the detection of environmental change signals by integrating advances in molecular biology, GIS, bioinformatics, and remote sensing into ecological indicator development. Ecological indicator application requires clear objectives, defined spatial and temporal scales, statistical rigor, stressor linkages, and integration with economic and social metrics, leveraging advances in molecular biology, GIS, bioinformatics, and remote sensing.

Abstract

▪ Abstract Ecological indicators have widespread appeal to scientists, environmental managers, and the general public. Indicators have long been used to detect changes in nature, but the scientific maturation in indicator development primarily has occurred in the past 40 years. Currently, indicators are mainly used to assess the condition of the environment, as early-warning signals of ecological problems, and as barometers for trends in ecological resources. Use of ecological indicators requires clearly stated objectives; the recognition of spatial and tempor al scales; assessments of statistical variability, precision, and accuracy; linkages with specific stressors; and coupling with economic and social indicators. Legislatively mandated use of ecological indicators occurs in many countries worldwide and is included in international accords. As scientific advancements and innovation in the development and use of ecological indicators continue through applications of molecular biology, computer technology such as geographic information systems, data management such as bioinformatics, and remote sensing, our ability to apply ecological indicators to detect signals of environmental change will be substantially enhanced.
