Human-caused habitat destruction, the major cause of species diversity losses, can be classified into two basic types, instantaneous destruction and continuous destruction. Thus, a universal model should be established to simulate and forecast the effects of different kinds of habitat destruction on ...

Different types of animals have been disappearing from view on the earth for millions of years.Now,one of them keeps popping up again,thanks to natural human curiosity.Mammoths(猛犸) could walk the earth again. With large tusks(长牙) and a high round head,mammoths were up to 5 meters tall...
The extinction of a single animal species can put huge pressure on the numerous other species dependent on it.Biodiversity also has an important role to play in human society. Apart from being the most intelligent species on earth, human beings are also the most dependent....
Since the extinction of rare species must be facilitated as the size of each reserve reduces, the area of a reserve should be larger than the critical area that ensures the persistence of the species. Hence it is concluded that one or a few large reserves are a better strategy in order ...
The team, led by Professor Zoe Davies from the University of Kent, found that, in general, the vast majority of species and traits are beneficial to human wellbeing. They also discovered that each species may support multiple traits, potentially with different impacts. ...
Because of human activities, the global rate of species extinction over the past 50 years has been higher than it has averaged over the past 10 million years. The species extinction could have serious effects on ecosystems. We fail to notice when losing one species, then another, then…These...

Describe at least one human effect on each of the biomes. Which terrestrial biome has the highest levels of species diversity? Why? What are the general differences in climate associated with the midlatitude deciduous forest and boreal forest biomes?
Different human activities typically lead to a variety of habitat types due to differential modifications of original microhabitats. Those changes in habitat conditions typically lead to non-random species loss4,5 resulting in poorer, functionally redundant, communities as functionally unique species tend...
