Question

Today you will be using an online visualization tool that illustrates the vulnerability to extinction of different groups of (mostly) terrestrial organisms. Spend some time looking through the website at projects.propublica.org/extinctions.

What group of organisms (mammals, reptiles, amphibians, or birds) has…

…the largest percentage of at-risk species? What’s the percentage?

…the smallest percentage? What’s the percentage?

Select any one family from the mammal, reptile, amphibian, or bird groups that has at least 40% of its species at risk for extinction (that is, the family grouping is colored red) and do some Internet research to identify some major mechanisms that have placed that members of that family at risk (e.g., climate change, habitat destruction, pollution).

Family:

Reasons for at-risk status:

Time for another website. You can google “Guardian endangered species map” – the site you want should be one of the top two search results – or you can type in the following: http://www.theguardian.com/environment/interactive/2012/sep/03/extinct-and-endangered-species-interactive. This map shows where species have already gone extinct and where the critically endangered species of today are located.

What country has had the largest number of extinctions since 1500? Within your group, talk about why this might be.

Now go to the “Critically endangered species” view of the map (upper right corner). Where are the spots with high concentrations of critically endangered species? For your answer, you can either list specific countries, continents, sub-continental regions (e.g., southeast Asia, northern Asia), or climatic zones (e.g., tropics, subtropics). Your choice.

Now go to the “In numbers” part of the map (upper right corner). By clicking on the circles, you can see which groups of organisms are most threatened in different regions of the planet.

After clicking on all of the regions on the map, can you make generalizations about what group(s) of organisms is/are most threatened globally? (For the purposes of this question, ignore the “plants, insects, and other” catchall category and focus on the other groups.)

Are there important regional differences that stood out to you?

Answer 1

CURRENTLY THERE ARE A LOT OF SPECIES OF DIFFRENT PHYLA ARE NEAR TO BE EXTINCT AND A LOT OF SPECIES ARE ACTUALLY EXIST . AS I WORKED ON THE PPTS AND EFFERTS OF OTHERS I FOUND THAT MOSTLY SPECIES SPECIES OF AMPHIBIA AND REPTILIA ARE EXTINCT AND MOST OF THEIR SPECIES ARE IN ENDANGERED CONDITION BUT MOST OF THE SPECIES OF THUS PHYLA ARE NEAR TO BE EXTINCT. AS PER REGIONAL EXTINCTION OF SPECIES IT IS BASED UPON THEIR EXISTANCE OR PLACE OF ORIGN THAT FROM WHERE THE SPEC IES GET ORIGNATED AND WHERE WILL IT EXTINCT OR NEAR TO EXTINCT SPECIES ARE ON THEIR EXTINCTION AS THEY ARENO WHERE EXIST IN NATURE
