Shelford's Law of Tolerance states that an organism's distribution and abundance are limited by the environmental factor(s) for which it has the narrowest range of tolerance. Conversely, organisms with a wide range of tolerance for environmental factors are called euryoecious species. - Organisms with a wide tolerance range can survive and reproduce across a broader spectrum of environmental conditions. - This ability allows them to inhabit a greater variety of locations and habitats, leading to a wide geographical distribution. - Within the wide range of conditions they can tolerate, there is likely an optimal range where the organism thrives, potentially leading to a high population density in suitable areas within their broad distribution. - Therefore, a wide environmental factor tolerance limit generally correlates with a wide distribution and the potential for high population size where conditions are favorable within that range.
According to Shelford's Law of Tolerance, the organisms wide environmental factor tolerance limit show :
