- What is the extinction crisis? 5 key facts | The Wilderness . . .
A species dying off also affects whatever species ate it, whatever predator ate that species, and so on—rippling outward along an intricate web of inter-species relationships that is the product of millions of years’ worth of evolution That includes humans who may rely on the affected plants or animals for food and shelter
- List of mammals of Mexico - Wikipedia
This is a list of the native wild mammal species recorded in Mexico As of September 2014, there were 536 mammalian species or subspecies listed Based on IUCN data, Mexico has 23% more noncetacean mammal species than the U S and Canada combined in an area only 10% as large, or a species density over 12 times that of its northern neighbors
- Most species that disappear today will leave no trace in the . . .
Today, humans are continually driving species to extinction—by one estimate, almost 500 vertebrate species have gone extinct in the past 100 years—but will those future scientists be able to tell? New research suggests that it might not be easy: Only a small proportion of these human-caused extinctions will leave behind a fossil trace—and

Results and Discussion The global distribution of overall mammalian species richness, restricted-range species, and threatened species is summarized in Fig 1 As we expected on the basis of a plethora of studies, species richness of mammals is concentrated in tropical regions throughout the world (9, 10)
