Calculate biodiversity using the biodiversity index and explain the meaning of the result. Materials Needed for this Lab Calculator / Excel / Google …

How does the species diversity vary in different geographical locations?

Dec 22, 2019 · See Page 1. Chose an area that is economically depressed but has a lot of species diversity, you need to protect the species while providing jobs for locals. An animal is being poached for its horn which is believed in some cultures to cure many diseases, it is not critically endangered. The demand for farming is increasing, which is destroying ...

Which is an example of an ecosystem with high species diversity?

Sep 13, 2016 · A) Islands closer to the mainland have higher extinction rates. B) As the number of species on an island increases, the emigration rate decreases. C) Competitive exclusion is less likely on an island that has large numbers of species. D) Small islands receive few new immigrant species. Answer: D 49)

Why is it important to maintain high species diversity in ecosystems?

From the data collected, it can be concluded that the urban areas of campus have the highest SDI of 2.2. Overall the urban community had the highest SDI with a combined value of 6.4 and the rural community has an SDI of 5.4. This means the urban area has the highest abundance of species diversity.

Which habitat would have greater species diversity?

tropical rain forests
There is more biodiversity within tropical ecosystems than temperate or boreal ecosystems. In fact, tropical rain forests have the most diversity.

Which type of habitat would have a greater species diversity a small forest or a large field of corn Why?

A small forest would have greater species diversity than a cornfield because species diversity tends to increase with diversity of habitats. A field consisting of just corn is a fairly uniform habitat and cannot support as much life.

What evidence suggest that we could be experiencing a sixth mass extinction?

What evidence suggests that we could be experiencing a sixth extinction? Today, species loss seems to be accelerating as human population growth puts an increasing strain on habitats and wildlife.

What are the benefits of biodiversity quizlet?

Biodiversity is important because it provides us with Natural Resources (Food, Water, Wood, etc.) Natural Services (Pest Control, Air and Water Purification, etc.) and of course, Aesthetic Pleasure.

What forest has the highest biodiversity?

Tropical rain forests are some of the most biologically diverse ecosystems on the planet.May 16, 2019

Which rainforest has the greatest biodiversity?

Tropical Amazonian rain forests in South America has greatest biodivesity. It may be due to following reasons : 1. Tropical latitudes have remained undisturbed for millions of years thus had a long evolutionary time for species diversification.

What is the most common reason of mass extinction?

The single biggest driver of mass extinctions appears to be major changes in Earth's carbon cycle such as large igneous province eruptions, huge volcanoes that flooded hundreds of thousands of square miles with lava.Sep 26, 2019

Which is most likely to cause a mass extinction?

The most commonly suggested causes of mass extinctions are listed below.
  • Flood basalt events.
  • Sea-level falls.
  • Impact events.
  • Global cooling.
  • Global warming.
  • Clathrate gun hypothesis.
  • Anoxic events.
  • Hydrogen sulfide emissions from the seas.

Which area of the world is considered more organisms are being destroyed?

Central America, Sub-Saharan Africa, and the Amazonian tropical rainforest areas of South America are the main regions with unsustainable agricultural practices and/or government mismanagement. Areas of high agricultural output tend to have the highest extent of habitat destruction.

Where are many critical biodiversity hotspots located?

Tropical forests are typically biodiversity hotspots and are usually filled with endemic species. The Upper Amazonia/Guyana Shield, the Congo Basin, and the New Guinea/Melanesian Islands have the highest number of endemic terrestrial (land-living) species on Earth [6].Mar 7, 2019

How is species biodiversity relevant to an ecosystem quizlet?

Biodiversity boosts ecosystem productivity where each species, no matter how small, all have an important role to play. For example, A larger number of plant species means a greater variety of crops. Greater species diversity ensures natural sustainability for all life forms.

What is the most important threat to biological diversity?

Habitat loss is the single greatest threat to biodiversity on Earth today and in fact it is the second largest threat to our existence on this planet next to Climate Change.Dec 1, 2020

Why is it important to maintain high species diversity?

In an ecosystem, all the species depend on each other directly or indirectly. So to make a more efficient, productive and sustainable ecosystem, it is important to maintain high species diversity. More diverse ecosystem tend to be more productive. E.g. the ecosystem with a great variety of producer species will produce large biomass ...

What is species diversity?

Species diversity is the measure of biological diversity observed in a particular ecological community indicating a number of species or species richness in an ecological community. Example – woodland forest comprising 4-5 different species of trees.

Why is species richness important?

Species richness makes an ecosystem able to respond to any catastrophe.

What is species richness?

Species richness makes an ecosystem able to respond to any catastrophe. In Species-rich communities, each species can use a different portion of resources available as per their requirement. E.g. plants with smaller roots can absorb water and minerals from shallow soil and plants with deeper roots can tap deeper soil.

What is the role of species in an ecosystem?

Each species plays an important role in an ecosystem. The role that a species plays in its ecosystem is known as its “ecological niche”. Species can be broadly divided into generalist and specialist species.

What are generalist species?

Generalist species: They have broad niches. These can live in many places and can eat a variety of foods. They can thrive in rapidly changing environmental conditions. E.g. cockroaches, rats, mice, flies, white-tailed deer, raccoons, humans, etc.

How many species of insects are there in the world?

There are about 5-10 million insect species present. 40% of the world’s 2,75,000 species of flowering plants are present in the tropical regions. 30% of total bird species are present in tropical forests. The species richness of tropical forests is mostly due to relatively constant environmental conditions.

What Does Species Diversity Mean?

Species diversity is a measurement of biological diversity to be found in a specific ecological community. It represents the species richness or number of species found in an ecological community, the abundance (or number of individuals per species), and the distribution or evenness of species.

Safeopedia Explains Species Diversity

Species diversity is a benchmark that can be used to evaluate the health of ecosystems. In a healthy ecosystem, a diverse and balanced number of species exist and maintain the equilibrium of the ecosystem.
