Maintaining biodiversity requires a considerable understanding of rarity and the processes and stresses that promote the endangerment of certain plant species Patient . [ Endangered_Plants 0 MCLH 15/03/2017 ]

Overexploitation for subsistence or commerce contributed to the endangerment of 30% of imperiled birds Patient but only 6% of amphibians (see Chapter 6). [ Endangered_Species_Management 0 MCLH 15/03/2017 ]

The overwhelming cause of plant species Patient endangerment is habitat loss, directly linked to agriculture, forestry, and urbanization. [ Endangered_Plants 0 MCLH 15/03/2017 ]

First, the leading cause of species Patient endangerment worldwide is habitat loss (Chapter 4). [ Endangered_Species_Management 0 MCLH 15/03/2017 ]

Surprisingly, pollution and introduced species, both of which are widely believed to be major causes of species Patient endangerment (Wilson 1992), are less important than either native species interactions or natural causes, neither of which are even listed as potential threats in similar studies (Wilcove et al. 1998).

As mentioned in Section II, a species become listed only after there is significant scientific evidence on its Patient endangerment. [ Patterns_of_Behavior_in_Endangered_Species_Preservation 0 MCLH 15/03/2017 ]
