Threatened species

of people on earth are reliant on four crops for subsistence; wheat, rice, corn, and millet. (11) These crops are threatened by climate change and the spread of disease facilitated by modern transportation. If humanity is to survive such an eventuality it must be ready to draw upon the earth’s biodiversity for replacements. And while there are approximately 50 thousand plant species that could offer alternatives, this bank of resources is quickly thinning as various ecosystems are being destroyed

It is recommended that Australian Paper implement the conservative practices, currently only applied to the Leadbeater’s Possum, to all threatened species whose habitats fall within the Gippsland region. This measure would maximise Australian Paper’s environmental sustainability by hindering biodiversity regression, potentially increasing a specie’s population through the provision of adequate habitats and could be the subject of promotion. Promotion of the new practice would better Australian Paper’s

as far north as southern Ontario (Brown and Weatherhead, 2000). The color of the northern water snake can vary from brown to gray and can have brown, red or black band marks found throughout their bodies. The Northern Water Snake is a nonvenomous species but if disrupted can inflict a painful bite that produces a musky smell (Schwarts et al., 2002). The northern water snake also exhibits sexual dimorphism in which the female is larger than the male (Bauman and Metter, 1977; Schwarts et al., 2002)

United States, mainly, in the state of California, reaching Oregon and northern Mexico (BBC, 2004). 3. One important species the live in the California Floristic Province is the Aloe adigratana (it has no common name). According to circumstantial evidence, it has been used as medicine. Another use of this plant is as a boundary fence. (Weber & Demissew, 2013) Another important species that live in the California Floristic Province is the weeping myall (Acacia pendula). It is a tree that can grow up

Planet Earth is home to millions of species with different forms of life. Due to habitat loss and destruction, hunting, climate change, agriculture, pollution, and deforestation, many animal and plant species have been decreasing significantly. Wildlife conservation, management plans, and acts have been passed in order to help preserve the diverse wildlife habitat An example of wildlife conservation is the Cosumnes River Preserve which is the largest river in central California with natural and unregulated

In areas of the world different species are becoming extinct at a rapid pace. This could be due to the environmental forces acting against them or through acts such as hunting. The reason why conservation biology has a deadline is because the effects of rising populations and the destruction with habitats as a result of the increase. If the event where extinction could occur is caught early enough then scientists would be able to perform conservation biology; however, in many instances if the environmental

A keystone species is a species that has a unequal effect on its environment relative to its abundance, affecting many other organisms in an ecosystem and help manage the types and numbers of many others species in a community. A keystone species is critical for the survival of other species in its community. If a keystone species is driven to extinction it is likely that other species will also disappear. Many animals depend on these keystone species for food, or other benefits that aid in their

reef is home to thousands of different species. Which include 1,500 species of fish, 411 types of hard coral, 134 species of rays and sharks, and 30 species of marine mammals. The reef system is even home to 6 out of 7 of the worlds threatened marine turtles. In addition to that are about 3,000 molluscs, thousands of different sponges worms and crustaceans, 630 species of echinoderms, and 215 species of birds (of which 22 are seabirds). All of these species make the reef on of the most diverse places

For many people, birds are seen to either be pets or wild animals. There is a massive amount of species when it comes to learning about birds. One of the birds that I decided to do my research paper on is Owls. The way I describe an owl is a type of bird that has a round head and large eyes, but there are plenty more ways to describe an owl which is the purpose of this paper. An interesting fact about owls is that they cannot move their eyes within their sockets like we can. In order to look around

general species alter biodiversity one of the example of human activity is the land use change. Human transformed a percentage between 40-50 of the ice-free land surface and also also changing prairies, forest and wetland into agricultural and urban system. The other example is by adding a species to the population and that has effect to other species in the area. 2) Why is it important to take species evenness into consideration rather than just species richness? Since evenness species respond
