A bear with a salmon. Interspecific interactions such as predation are a key aspect of community ecology.. In ecology, a community is a group or association of populations of two or more different species occupying the same geographical area at the same time, also known as a biocoenosis, biotic community, biological community, ecological community, or life assemblage.
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.
The umwelt theory states that the mind and the world are inseparable because it is the mind that interprets the world for the organism. Because of the individuality and uniqueness of the history of every single organism, the umwelten of different organisms differ.
Environmentalism or environmental rights is a broad philosophy, ideology, and social movement about supporting life, habitats, and surroundings.While environmentalism focuses more on the environmental and nature-related aspects of green ideology and politics, ecologism combines the ideology of social ecology and environmentalism.

Population: A group of conspecific individuals that is demographically, genetically, or spatially disjunct from other groups of individuals. Aggregation: A spatially clustered group of ...
Hubbell built on earlier neutral models, including Robert MacArthur and E.O. Wilson's theory of island biogeography [1] and Stephen Jay Gould's concepts of symmetry and null models. [7] An "ecological community" is a group of trophically similar, sympatric species that actually or potentially compete in a local area for the same or similar ...
Socio-ecological models were developed to further the understanding of the dynamic interrelations among various personal and environmental factors. Socioecological models were introduced to urban studies by sociologists associated with the Chicago School after the First World War as a reaction to the narrow scope of most research conducted by developmental psychologists.
But human ecology is neither anti-discipline nor anti-theory, rather it is the ongoing attempt to formulate, synthesize, and apply theory to bridge the widening schism between man and nature. This new human ecology emphasizes complexity over reductionism , focuses on changes over stable states, and expands ecological concepts beyond plants and ...
