What is Landscape Ecology What is Ecology? · What is a landscape? Ecology interactions between( living organisms and ()environment structures and processes Landscape Bigger than 'plot=1m x 1m40m x 40m Heterogeneous Scale Spatial characteristics
What is Landscape Ecology? • What is Ecology? • What is a Landscape? • Ecology = interactions between (I) living organisms and (ii) environment = structures and processes • Landscape = Bigger than ‘plot’ = 1m x 1m 40m x 40m = Heterogeneous = Scale = Spatial characteristics
Ecology study of living organisms in its relation with the environment(Haeckel 1866)

Landschaft a community of a higher order consisting of communities of organisms, including plants, animals (and people) together with the complex of inorganic phenomena, eg the form of the relief, the water, and the climatic factors Berg 1913)

Ecosystem Whole complex of organisms and factors of environment in an ecological unit of any rank(Tansley 1939) the ecosystem consists of both organic and inorganic components, which may be conveniently grouped under the heads of climate, physiography, and soil, plants and animals

Ecosystem(contd) Verdansky(Russia, 1940s)introduced concept of global biobeochemical cycles (water, carbon, nitrogen, etc. related to concept of ecosystem as it looks at the flows of matter through biotic and abiotic compartments
