Introduced species

The contemporary lawn does not deviate from this pattern. As shown in Table 2.1, the dominant turf grasses of the United States-used in lawns, playing fields, parks, and golf courses-are all introduced species. Moreover, many are species that arrived in the New World as forage plants for cattle. In...

This scheme adapts nicely to endemic species and, to a certain extent, also to species that have been introduced from a long time. In contrast, cultivated and recently introduced species can hardly be dealt with satisfectorily by any kind of ecosystem subdivision. 

Another important mode of operation in SPME is in-tube SPME.65 In this system, usually coupled on-line to HPLC, a finite portion of sample is drawn through an internally coated capillary tube and then ejected into the sample vial. This technique requires more complex instrumentation than that used for standard SPME, but a greater sensitivity is obtainable with a longer tube (and consequently more sorbent). Two solvent desorption modes—are usually applied for introducing species into HPLC off-line desorption and on-line desorption. In the latter, the HPLC mobile phase is used for desorbing the analytes.
