The role of biology in relation to the environment.
" keep, save" is a new discipline of biology that studies all aspects of biodiversity with the goal of saving natural resources for future generations.
The development of scientific concepts and the application of these concepts to the everyday world is what conserve biology is concerned with.
The management of the variety of life on Earth is the primary goal of the biology.
To achieve this goal, many subfields of biology have been brought together.
Disciplines that support the study of biology.
There is a large diversity of biological fields.
The components of the large picture are contributed by each field.
The latest theoretical and practical findings are important for biologists.
They need to use this knowledge to find the source of the problems and suggest courses of action.
From the local to the federal level, biologists work with government officials.
Public education is an important part of this profession.
Scientists must look at the larger connections within the biosphere in order to be an effective field of study.
The stability of the ecosystems is influenced by a high level of biodiversity.
Stable ecosystems contribute to the health of the human population.
Negative consequences for the human population are often the result of the reverse.
The Earth is experiencing an extinction crisis.
Unless coordinated actions are taken, at least 10% of all species will become extinct in the next 20 to 50 years.
The concept and importance of biodiversity, the causes of present-day extinctions, how to prevent future extinctions from occurring, and the potential consequences of decreased biodiversity are important to all citizens.
Scientists can use modern computer technology to collect, analyze, and make readily available biological information.
Information on organisms is collected throughout the world for study.
In terms of the number of species present among various groups of organisms, it is a common practice.
Over two million species have been described and catalogued across the globe.
This may be a small portion of Earth's species.
Some people think that there are more than 8.7 million species on the planet.
Most species have yet to be described.
Half of the species are insects.
There are between 8.7 and 50 million species on Earth.
The U.S. states that.
There are over 500 animal and plant species that are in danger of extinction in the United States.
There are over 30,000 species in danger of extinction.
It is in danger of immediate extinction throughout all or most of its range.
The sedge, northern spotted owl, and coho salmon are examples of threatened species.
We need to know more about species than just the number of them.
Populations with high genetic diversity are more likely to have some individuals that can survive a change in their environment.
These populations are more adaptive than those with limited flora.
The Potato Blight in Ireland, the 1922 wheat failure in the Soviet Union, and the 1984 outbreak of citrus canker were all made worse by limited genetic variation among these crops.
A small population is more likely to have limited genetic diversity.
Small populations are more likely to go extinct.
One community's species composition can be very different from another's.
The levels of biodiversity in the biosphere are increased by diverse community compositions.
The black-footed ferret or spotted owl are examples of charismatic species that have been saved in the past.
This approach is short-sighted.
There are species that play a critical role in the environment.
Saving an entire community can save a lot of species.
The shrimp ate a lot of zooplankton, which meant less food for the fish.
There was a decrease in the available food for the bald eagles.
Humans were the first to introduce the shrimp to salmon.
The shrimp competed with salmon for zooplankton.
The salmon, eagle, and bear populations declined.
Landscape interactions are studied for landscape diversity.
A landscape includes mountains, rivers, and grasslands.
Sometimes, the ecosystems are so fragmented that they are only connected by small patches of land that allow organisms to move between them.
Shrinking the landscape can affect reproductive capacity and food availability.
It is not evenly distributed.
If we have to protect only small areas, we should focus on the best parts of the world.
In the tropics, it is higher and in the poles it is lower.
The coral reefs of the Indonesian archipelago are the most diverse in the world.
Some regions of the world contain a lot of species.
More than half of all known higher plant species and more than a third of all terrestrial vertebrate species are found in the hotspots.
