Categories and classes: Definitions: References (I) DESCRIPTIVE CONCEPT (Ia) ECOLOGICAL SCIENCE: 1) Original-ecological: Measure of the persistence of systems and of their ability to absorb change and disturbance and still maintain the same relationships between populations or state variables The Phosphorus Paradox: this is the story of phosphorus, the first element isolated and discovered by modern science. The Sustainable Watersheds Program at Penn State: this program engages local watershed partners and provide increased engaged scholarship opportunities for Penn State students. Original Definition. Terms in this set (609) air pollution. Resistance definition is - an act or instance of resisting : opposition. Total insulation resistance of looped lines = 2 R(D/d - 1); in which R is the total resistance of the looped wires, including the resistance of the two coils of the galvanometer, of the battery, and of the two resistance coils r and r' (inserted for the purpose of causing the leakage on the lines to have a maximum effect on the galvanometer. See more. The voltage is equivalent to the water pressure, the current is equivalent to the flow rate, and the resistance is like the pipe size. There is a basic equation in electrical engineering that states how the three terms relate. It says that the current is equal to the voltage divided by the resistance or I = V/R. environmental resistance The sum total of the environmental limiting factors, both biotic and abiotic, which together act to prevent the biotic potential of an organism from being realized. If uni-directional change is an ongoing process (for example climate change), the system will also lose resilience after a certain time, as full recovery through succession will then not be possible. Original resilience concepts (as described by Holling 1973 and clarified in Gunderson 2000) emphasize that complex systems, including ecosystems, are hierarchically structured, meaning that patterns and processes are compartmentalized by distinct scales of space and time.Resilience, therefore, captures the richness of behavior in complex systems better than … Such factors include the availability of essential resources (e.g. This is known as Ohm's law. Science The Resistance: In the President’s Relentless War on Climate Science, They Fought Back ... with the overall number of outside advisers at EPA and other environmental science … How to use resistance in a sentence. Other articles where Environmental resistance is discussed: biotic potential: …an organism is restricted by environmental resistance, any factor that inhibits the increase in number of the population. Resistance breaks down when uni-directional environmental change acts faster than the organisms' ability to adapt their tolerances. In environmental science, resistance refers to the environmental factors which limit the population growth of a species. A list of important vocabulary presented in AP Environmental Science. Resistance definition, the act or power of resisting, opposing, or withstanding. Based on the course offered by FLVS.
