Sentence examples for extinction of a native from inspiring English sources

Though no extinction of a native species is yet attributable to invasion of new species, sudden declines in abundance, concurrent with proliferation of aliens, have been recorded [216].

These findings suggest that patterns of seed dispersal are altered following the local extinction of a native island frugivore.

A habitat size 55% greater for P. ridibundus as compared to P. lessonae leads to the extinction of all native frogs, irrespective of the level of interbreeding success rate with the hybrid P. esculentus (data not shown).

However, a greater habitat size available for P. ridibundus (V L < V R R ) leads to the extinction of all native frogs, excepting the case in which the reproduction between P. ridibundus and the hybrid is panmictic (γ RE  = 1).

While biologic invasions are considered a significant threat to biodiversity (Sala et al. 2000; Stein et al. 2000), they do not result in the extinction of all native species impacted; many native species are able to persist alongside invaders (Hironaka and Tisdale 1963; Levine and Rees 2004; Mealor et al. 2004; Stohlgren et al. 2006).

If the proportion of heterotypic matings of P. lessonae represents 2 3 of the homotypic matings (γ LR  > 0.66), the extinction of all native frogs is reached and is almost independent from the interbreeding success rate of P. ridibundus (γ RL  ≠ 0).

For P. ridibundus coming from Central Europe and producing new fertile hybrids, a complete extinction of both native frogs is expected if the habitat size of P. lessonae is equal or smaller than that available for P. ridibundus (V L = V R R or V L < V R, Figig. 3B).

A similar case involves the decline and partial extinction of the native noble crayfish Astacus astacus in many European lakes which was probably driven by the fungal pathogen Aphanomyces astaci introduced to Europe with the North American signal crayfish Pacifastacus leniusculus (Josefsson & Andersson, 2001).

These results mirror the important demographic impact of the European colonizers in Guatemala (with a large effective population size) and their role in the extinction of the Native American population from the region.

Extinction of native species is a matter of much concern.

Exporting countries need to take steps against giving free rides to such invaders, which are causing the extinction of some native species, the group said.
