An organisms capacity to survive variation in environmental conditions. c. They attract predators of the pest. d. They prevent the pest from attacking the plant by poisoning its nervous system. Ecological succession is dynamic process occurs due to relatively different sequence of communities over the period of time in the same area. See below. 3.7 . There are four factors that affect range of tolerance: time, place, situation, and culture. Abiotic factors affecting ecological niche include temperature, landscape characteristics, soil nutrients, light and other non-living factors. Although Shelford's "law of tolerance" is still given significant coverage in some ecology texts (Odum 1971), it has largely been supplanted by the concept of the niche (Whittaker and Levin 1975), which underlies many ecological and evolution- They disrupt the pest's life cycle. Tolerance in the plant ecological literature . Range where organisms survive, grow, and reproduce. . Tolerance is defined as the total permissible variation of a size. Article shared by : Some of the major ecological factors that constitute the environment of an organism are as follows: 1. Abstract Plants acquire enhanced tolerance to intermittent abiotic stress by employing information obtained during prior exposure to an environmental disturbance, a process known as acclimation or defense priming.

The ecological tolerance of a population can be defined by considering and investigating its growth potential as a function of environmental variables. Organisms have ranges of tolerance for environmental factors. In the above examples of tolerance in animals, measures of disease severity, longevity or survivability were being used as a measure of reproductive output. Even is all the other factors are optimum, it's the one most likely to regulate population growth, Often nitrogen, phosphorus, or potassium-this is why NPK testing kits are used and why those nutrients are components of fertilizers, Sometimes nitrogen, silica or iron; sometimes dissolved oxygen (DO). The most important abiotic factors for plants are light, carbon dioxide, water, temperature, nutrients, and salinity. That is their range of tolerance. Quick Reference.
