Ecosystems are composed of dynamically interacting parts including organisms, the communities they make up, and the non-living components of their environment.

Ecosystems are habitats within biomes that form an integrated whole and a dynamically responsive system having both physical and biological complexes.

Ecosystems are complex adaptive systems where the interaction of life processes form self-organizing patterns across different scales of time and space.

Ecosystems are broadly categorized as terrestrial, freshwater, atmospheric, or marine.

Ecosystems are controlled both by external and internal factors.

Ecosystems are dynamic entities — invariably, they are subject to periodic disturbances and are in the process of recovering from some past disturbance.

Ecosystems in similar environments that are located in different parts of the world can end up doing things very differently simply because they have different pools of species present.

Ecosystems continually exchange energy and carbon with the wider environment ; mineral nutrients, on the other hand, are mostly cycled back and forth between plants, animals, microbes and the soil.

Ecosystems are composed of a variety of abiotic and biotic components that function in an interrelated way.

Ecosystems receiving more nitrogen than the plants require are called nitrogen-saturated.

Ecosystems are no different than other bodies economically except insofar as they are far less replaceable than typical labour or commodities.

Ecosystems in and around the urban center are especially influenced by these point sources of pollution.

A feature distinguishing it from prior economic regimes is the direct valuation of natural capital and ecological services as having economic value ( see The Economics of Ecosystems and Biodiversity and Bank of Natural Capital ) and a full cost accounting regime in which costs externalized onto society via ecosystems are reliably traced back to, and accounted for as liabilities of, the entity that does the harm or neglects an asset.

Further, DOP / UAç are participants in Steering Committees for three great initiatives by Census of Marine Life program: ChEss ( Biogeography of Chemosynthetic Ecosystems ), MAR-ECO ( Patterns and Processes of the Ecosystems of the Mid-Atlantic Ridge ) and CenSeam ( A Global Census of Marine Life on Seamounts ).

Although pig-nosed turtles are protected in Indonesia under Law No. 5 / 1990 on Natural Resources and Ecosystems Conservation, smuggling occurs.

He presented an early version of this approach in a Harvard Business Review article entitled Predators and Prey: A New Ecology of Competition in May / June 1993, as well as in a book, The Death of Competition: Leadership and Strategy in the Age of Business Ecosystems A more recent treatment by Harvard Business School faculty members Marco Iansiti and Roy Levien, is their book The Keystone Advantage: What the New Dynamics of Business Ecosystems Mean for Strategy, Innovation, and Sustainability.

Ecosystems maintain biophysical feedback mechanisms that modulate metabolic rates and evolutionary dynamics between living ( biotic ) and nonliving ( abiotic ) components of the planet.

Ecosystems sustain life-supporting functions and produce natural capital through the regulation of continental climates, global biogeochemical cycles, water filtration, soils, food, fibres, medicines, erosion control, and many other natural features of scientific, historical, economic, or intrinsic value.

Ecosystems regenerate after a disturbance such as fire, forming Mosaic ( ecology ) | mosaics of different age groups structured across a Landscape ecology | landscape.

Ecosystems, for example, contain populations of individuals that aggregate into distinct ecological communities.

Ecosystems provide a variety of goods and services upon which people depend ; the principles of ecosystem management suggest that rather than managing individual species, natural resources should be managed at the level of the ecosystem itself.

Well-funded groups like Canada's Ballard Power Systems are also working to develop a " regenerative fuel cell ", a device that can generate hydrogen and oxygen when power is available, and combine these efficiently when power is needed.

Biologists are especially interested in hydras due to their regenerative ability ; and that they appear not to age or die of old age.

In a developing embryo, stem cells can differentiate into all the specialized cells ( these are called pluripotent cells ), but also maintain the normal turnover of regenerative organs, such as blood, skin, or intestinal tissues.

* c. 6000 BC: Female figurines holding serpents are fashioned on Crete and may have been associated with water, regenerative power and protection of the home.

Special types such as regenerative amplifiers and chirped-pulse amplifiers are used to amplify ultrashort pulses.

These are not the same as the ready and regenerative divisions ( see below ), but are based on either the geographical recruiting areas of regiments, or the type of regiments:

The IGBT is a semiconductor device with four alternating layers ( P-N-P-N ) that are controlled by a metal-oxide-semiconductor ( MOS ) gate structure without regenerative action.

Another related mechanism is that of the biologically immortal planarian flatworms, which have “ apparently limitless regenerative capacity fueled by a population of highly proliferative adult stem cells .” These organisms are biologically immortal but not immortal in the traditional sense as they are nonetheless susceptible to trauma and infectious and non-infectious disease.

Without once looking back, take ye your part in this regenerative work of deliverance through self-annulment ; then are we one and un-dissevered!

The second group is the non-phagocytic types that are distributed near regenerative fibers.

Due to these features the regenerative kilns are today mainstream technology under conditions of substantial fuel costs.

Paddle shifters are used to adjust the amount of regenerative braking.

These TGV-derived components are the traction system derived from third-generation TGV trainsets ( including the four asynchronous AC motors per power car, rectifiers, inverters, and regenerative braking technology ), the structure of the trucks / bogies ( with a long wheelbase dual transom H frame welded steel with outboard mounted tapered roller bearings ), the brake discs ( although there are only three per axle, versus four on the TGV ), and the crash energy management techniques to control structural deformations in the event of an accident.

Old people have limited regenerative abilities and are more prone to disease, syndromes, and sickness than younger adults.

Electric traction allows the use of regenerative braking, in which the motors are used as brakes and become generators that transform the motion of, usually, a train into electrical power that is then fed back into the lines.

Furthermore, regarding plastic surgical scars, the age of the patient is a notable factor in the timely, post-surgical healing of a skin cancer defect ( lesion ); in terms of scarrification, the very elastic skin of young people has a greater regenerative propensity for producing scars that are thicker ( stronger ) and more noticeable.

The rail cars are full of thousands of tons of iron ore on the way down to Narvik, and these trains generate large amounts of electricity by their regenerative braking.

* Most road vehicles with regenerative braking only have power on some wheels ( as in a two-wheel drive car ) and regenerative braking power only applies to such wheels because they are the only wheels linked to the drive motor, so in order to provide controlled braking under difficult conditions ( such as in wet roads ) friction based braking is necessary on the other wheels.

Transistors, either bipolar or JFETs are used in regenerative receivers today.

Other shortcomings of regenerative receivers are the presence of a characteristic noise (“ mush ”) in their audio output, and sensitive and unstable tuning.

Appellate court credited De Forest with the regenerative circuit: " The decisions of the Commissioner are reversed and priority awarded to De Forest.
