An environmental factor, ecological factor or eco factor is any factor, abiotic or biotic, that influences living organisms. [1] Abiotic factors include ambient temperature, amount of sunlight, air, soil, water and pH of the water soil in which an organism lives.
An environmental gradient, or climate gradient, is a change in abiotic (non-living) factors through space (or time). Environmental gradients can be related to factors such as altitude , depth, temperature , soil humidity and precipitation .

[43] Apart from labile organic carbon, spatial separation of microbes in soil may be influenced by other environmental factors such as temperature and moisture. [44] Other abiotic factors like pH and mineral nutrient composition may also influence the distribution of microorganisms in soil. [45] Variability of these factors make soil a dynamic ...
An early study on ecological niches conducted by Joseph H. Connell analyzed the environmental factors that limit the range of a barnacle (Chthamalus stellatus) on Scotland's Isle of Cumbrae. [78] In his experiments, Connell described the dominant features of C. stellatus niches and provided explanation for their distribution on intertidal zone ...
Limited cognition barriers are barriers that arise from a lack of knowledge and awareness about environmental issues. For example, with a key environmental issue like climate change, a person might not engage in pro-environmental behaviour because they are: unaware that climate change is occurring; or aware that climate change is an issue, but are ill-informed about the science of climate ...
Ecologically sustainable development is the environmental component of sustainable development.It can be achieved partially through the use of the precautionary principle; if there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation.
Population ecology is a sub-field of ecology that deals with the dynamics of species populations and how these populations interact with the environment. [15] It is the study of how the population sizes of species living together in groups change over time and space, and was one of the first aspects of ecology to be studied and modelled mathematically.
