Sentence examples for extinction relationship from inspiring English sources

Giller et al. (1998) proposed two possible relationships between stress levels and microbial community diversity: an "extinction" relationship in which the diversity of a community is negatively correlated to an increase in stress levels, and a "competitive exclusion" relationship in which there is a hump-backed response to stress.

Herbivore grazing affects grassland dynamics, changing the species colonisation and extinction relationships via consumption, mechanical disturbance, seed dispersal and altered soil fertility due to dung-borne nutrient input.

The question of which biological system underpinned the lumbering success of the dinosaurs is arguably "the last big one", Mr Grady told the BBC - following other big debates over their extinction and their relationship to birds.

In 55 plots where extinctions occurred, there was no significant relationship between extinction and MNND; in three plots, extinctions were significantly clustered relative to the species that persisted (P<0.05), and in one plot, extinction was over-dispersed (P<0.05).

Li et al. [11] showed that both stochastic permanence and extinction have close relationships with the stationary probability distribution of the Markov chain.

The relationship between extinction rate and dispersal might, however, become hump-shaped with very high extinction rates selecting for reduced dispersal [ 40].

Crucially for understanding the relationship between extinction and evolution is this: New species do not suddenly "arise," nor are they really new.

And his article comes at a time when conservation is being assailed from other quarters, with a half-century of federal protections of land being rolled back, the Endangered Species Act now more endangered than ever, and the relationship between extinction and evolution being subjected to confused, book-length mistreatment.

Research evaluating the relationship between extinction and human impact showed that, after controlling for species richness, the best predictors of the global pattern of extinction risk are measures of human impact, with ecological factors being of secondary importance.

However, our analysis suggests that dietary specialization also has some direct relationship to extinction risk in vespertilionid bats.

Therefore, we used traditional and phylogenetically-controlled analysis of variance to test for a relationship between extinction risk and dietary breadth [3].
