Measuring stream metabolic state is important to understand how disturbance may change the available primary productivity, and whether and how that increase or decrease in NEP influences foodweb dynamics, allochthonous / autochthonous pathways, and trophic interactions.

A classic site for the study of biocolonisation from founder populations that arrive from outside ( " allochthonous " ), Surtsey was declared a nature reserve in 1965, while the eruption was still in active progress.

San Lorenzo de El Escorial also has some allochthonous in its mountain areas, plant species as beech ( American beech ), cedars, larches, Lawson cypresses ( Chamaecyparis lawsoniana ), and sycamores ( Acer pseudoplatanus ).

There are two theories the autochthonous ( " in situ " ) theory and the allochthonous ( drift ) theory that attempt to explain the formation of coal balls, although the subject is mostly speculation.

During the rainy season, " T . piresi " is an omnivore that feeds mainly on allochthonous food items such as fruits, seeds, flowers, and animals from the igapo, permanently flooded land where roots of vegetation are always submerged.

The Lesser Himalaya thrust over the Siwaliks along the MBT to the south, and is overlained by the allochthonous thrust sheets of Kathmandu and HHC along the MCT . The Lesser Himalaya is folded into a vast post-metamorphic anticlinal structure known as the Kunchha-Gorkha anticlinorium.

All three endemic trout species of the Neretva are endangered mostly due to the habitat destruction or construction of large and major dams ( large is higher than 15 20 m; major is over 150 250 m ) in particular and invasive allochthonous species ( dams, overfishing, mismanagement, genetic pollution, invasive species ).

On the basis of all relevant indicators it is necessarily to take urgent measures, continuous and organized action, to dramatically reduce the quantity ( if is not possible to exterminate ) of this allochthonous type of fish, as well as to attempt to revitalize autochthonal fish populations, with fish stocking of local, especially salmonids species, all in order to prevent the same fatal experience with the water ecosystem in the UK, and prevent, if possible, this type of allochtonous species colonization of the Neretva River basins with irreversible effects.

An analysis by Kevin Chamberlain " et al . " ( 2003 ), on the basis of differences in late Archean histories, subdivides the Wyoming Province into five subprovinces : three in the Archean core, ( 1 ) the Montana metasedimentary province, ( 2 ) the Bighorn subprovince, and ( 3 ) the Sweetwater subprovince, and two Archean terrains that may have originated elsewhere ( that is, allochthonous to the 3.0 Ga craton ), ( 4 ) the Sierra Madre Medicine Bow block, and ( 5 ) the Black Hills Hartville block.
