Once they created a species they determined they could trust, they tasked them with creating yet more sapient species after the whole of their own species had " passed on ".

Once a suitable area is located, a prey species is hunted and used as bait.

Once a wild and pristine environment rich with native wildlife, non-native species such as the dozens of domesticated ducks and geese and Eurasian mute swans released here by people over the years, as well as artificially high amounts of food due to feedings have produced an environment that holds far more animals than the area could ever naturally sustain.

Once completed, the zoo is expected to house about 500 animals belonging to 50 different species.

Once established, pairs remain together to breed for life ; however, extra-pair copulations are common, making this species genetically polygamous, despite being socially monogamous.

Once known simply as " desert rats ", the gerbil subfamily includes about 110 species of African, Indian, and Asian rodents, including sand rats and jirds, all of which are adapted to arid habitats.

Once widespread in arid, semi-arid and relatively fertile areas, the bilby is now restricted to arid regions and remains a threatened species.

Once widespread across southern Australia, the range is now restricted to several small colonies and it is listed as an endangered species.

Once they become adults, most crane fly species exist as adults only to mate and die.

Once feathers begin to erupt, the nestlings are unusual for altricial birds in having plumage coloured with carotenoids similarly to their parents ( in most species it is dun-coloured to avoid predation ).

Once a reversal in climate change allows for rapid migration out of refugial areas, these species spread rapidly into newly available habitat.

Once herbivorous megafauna species became extinct, carnivorous megafauna species soon followed.

Once their habitat is destroyed, they cease to exist. This destruction has a follow-on effect, as species which coexist or depend upon the existence of other species also become extinct, eventually resulting in the collapse of an entire ecosystem.

Once breeding is over, this species will readily move into deciduous trees and shrubs, heathland and similar more open habitats.

Once the land was semi-drained, it had to be turned into pasture.

Once upon a time in a bid to look for greener pasture, a group of Malaysian traders boarded a vinta sailing across many islands and accidentally landed in an island what is now Tandubas Island.

Once the English settlers began to enclose the marsh for pasture and the tide no longer flushed-out the haven, it silted up and Bicker changed from port to farming village.

Once in the body, the bacteria can enter the lymphatic system, which drains interstitial fluid.

Once a prototype has passed the tests at a certification lab, and that model is being constructed under the control of a certified quality system, the device is entitled to bear a CE mark, indicating that the device is believed to be safe and reliable when used as directed.

Once judges began to regard each other's decisions to be binding precedent, the pre-Norman system of local customs and law varying in each locality was replaced by a system that was ( at least in theory, though not always in practice ) common throughout the whole country, hence the name " common law.

Once he retired, however, his Tetrarchic system collapsed.

Once more assuming his Bowman form, Dave contacts Dr. Heywood Floyd via HAL's communication system.

Once the system can be solved, given an initial point it is possible to determine all its future positions, a collection of points known as a trajectory or orbit.

Once the transmission characteristics of a system are determined, telecommunication engineers design the transmitters and receivers needed for such systems.

Once stored in the interface, the information is no longer subject to timing issues associated with USB jitter and computer operating system interrupts, and can be transmitted with a high degree of accuracy.

Once the application opens a file that contains a macro virus, the virus can infect the system.

Once application migration is completed, IBM recommends migration to a different operating system, suggesting Linux as an alternative.

Once in production, the 912E was powered by an 86 bhp 2. 0 L Volkswagen air-cooled engine, refined with a new Bosch L-Jetronic ( Air Flow Controlled ) fuel injection system.

Once a failure mode is identified, it can usually be mitigated by adding extra or redundant equipment to the system.

Once again the game system was replaced, this time with the GURPS system from Steve Jackson Games, but the setting was returned to the one laid out in the original Traveller, albeit as an alternate history in which the assassination and subsequent fall of the Third Imperium never happened.

Once introduced, the expedite system remains in force until the end of the match.

Once the speculation is wrung out of system the cycle of land speculation begins again.

Once the bulk of the outgassing materials are boiled off and evacuated, the system may be cooled to lower vapour pressures to minimize residual outgassing during actual operation.

Once a project is complete, the NLE system can then be used to export to movie in a variety of formats in context which may range from broadcast tape formats to compressed formats for the Internet, DVD and mobile devices.

Once air progresses through the mouth or nose, it travels through the oropharynx, nasopharynx, the larynx, the trachea, and a progressively subdividing system of bronchi and bronchioles until it finally reaches the alveoli where the gas exchange of carbon dioxide and oxygen takes place.

Once fully deployed, the system is used for its intended operational role and maintained within its operational environment.

Once deployed, the effectiveness and efficiency of the system must be continuously evaluated to determine when the product has met its maximum effective lifecycle.

Once experiments with this system yielded successful results, the government officially sponsored it and encouraged peasants to use it.

Once the sound effects are recorded or captured, they are usually loaded into a computer integrated with an audio non-linear editing system.

Once installed, the operating system ( BIOS, BDOS and CCP ) was stored in reserved areas at the beginning of any disk which would be used to boot the system.
