Ecosystem diversity is often evaluated to measure the diversity of the constituent species, the relative abundance of different species as well as contemplation of the type of species. Elton also proposed the pyramidal structure of the food chain in considering how the size and populations of a species (as food or consumer) relate to its position in the pyramid (e.g., smaller populations of slowly reproducing, large predators such as whales depend upon larger numbers of rapidly reproducing,tiny zooplankton). Theseefforts produced a vast array of metricsto describethe spatial arrangement of habitatpatches, suchas fragmentation, fractal dimension, connectivity, and contagion, as well as techniques to determine the appropriate scale at which pattern-process relationships of interest could be analyzed and correlated. Existing ecological theories focusing on individual species, populations, communities, or niches aid in understanding the determinants of biodiversity patterns, yet very few general models for biodiversity have emerged from simplistic approaches. 1995, Kunin and Lawton 1996, Schwartz et al. As developments in ecology continued over the next several decades, advances were made in the understanding of global bio-geochemical cycles (e.g., the nitrogen cycle); and the term biosphere cametobecoined in1875 by geologist Eduard Suess, to refer to that global sphere where the biota interacts with the lithosphere, atmosphere and hydrosphere. Odum applied the strategic ecosystem approach to ecological communities in their successional paths, theorizing that older, more advanced communities should contribute to overall ecosystem stability, or homeostasis, securing protection against environmental disturbances.

While ecologists overwhelmingly acknowledge the interactions between bioticand abiotic components of the biosphere, as well the ability of biota to alter its physical environment, they debate the concept of homeostasis implied in the Gaia hypothesis and criticize the hypothesis itself for being overly teleological. The term ecology derivesfrom oekologie, first coined in 1866 by the biologist Ernst Haeckel, joining the Greek oikos, or household, and logos, orstudy.The field of ecology combines diverse scientific traditions from natural history, experimentation, field study and mathematical modeling toadvanceour understanding of the processesand patterns maintaining and altering biodiversity.

Experiments by Tansley and others mustered support for the importance of inter-specific competition in determining the presence of absence of a species, although the results were mediated by environmental conditions. It is far more ecologically and economically feasible to manage disturbance regimes rather than restore landscapes or ecosystems after dramatic degradation. Fritjof Capra goes on to suggest that the concept of “ecological literacy” includes the insight and knowledge needed in order for man to create and uphold sustainable societies.

From a policy perspective, many ecosystem ecologists advanced the preservation of nature untouched, as far aspossible,bythe human hand.

Ecology’s general identification with the studyand valuationof nature, moreover, makes itacommon ifsometimes unwilling ally in the modern environmental movement since the 1960s. Ecological complexity in a broad sense refers to biodiversity including diversity of genotypes, species, functional types, landscapes and interactions within and between these levels of organization, as well as, diversity and interaction of trophic pathways producing connectivity between ecosystems. Kim, y. Different species have different functional roles to play in ecosystems which help maintain the characteristics unique to that ecosystem. Landscape functionrefers tothe interaction of landscape componentsandthe flow of organisms, materials, andenergythrough the landscape. Diverse characteristics can often include race, gender, ethnicity, class, exceptionality, and orientation. Among such processes are competition, predation, dispersal and extinctions. Different types of reefs and their formation. Scientists have long assumed that the physical structure and condition of stream and river channels have pervasive effects on biological communities and processes (Hynes, 1970; Allan, 1995).
