Red Data Book or IUCN Red List provides data on

biology main natural resources classification of threatened species red data book methods of conservation

  1. Biota of Red Sea

  2. Effect of red light or photosynthesis

  3. Red pigmented plants

  4. Threatened species

Show answer
Correct Option: D
Explanation:

The species (including animals, plants, fungi, etc.) which are vulnerable to endangerment in the near future are known as threatened species. The International Union for Conservation of Nature (IUCN) is the authority on threatened species, and it treats threatened species as a group of three categories, depending on the degree relative to which they are threatened. Those categories are Vulnerable species; Endangered species and Critically endangered species. As per the Red list of 2000, there are 11,096 threatened species.

So, the correct answer is 'Threatened species'.

In India, red list of plant species is prepared by

biology main natural resources classification of threatened species red data book methods of conservation

  1. Botanical Survey of India

  2. Forest Department of India

  3. Geological Survey of India

  4. Census Department of India

Show answer
Correct Option: A
Explanation:

In India, red list of plant species is prepared by Botanical Survey of India. Botanical Survey of India is Government of India Ministry of Environment, Forest and Climate Change's organization for the survey, research, and conservation of plant resources, flora and endangered species of India. It was founded on 13 February 1890, by the East India Company. The headquarters are located in DF Block, Sector I, Salt Lake City, Kolkata.

So, the correct answer is 'Botanical survey of India'.

According to IUCN Red List, during the last two decades, the maximum increase in the number of threatened species is among

biology main natural resources classification of threatened species red data book methods of conservation

  1. Mammals

  2. Amphibians

  3. Reptiles

  4. Birds

Show answer
Correct Option: B
Explanation:
According to the IUCN Red List, during the last two decades, the maximum increase in the number of threatened species is among amphibians as some groups like amphibians appear to be more vulnerable to extinction. More than 15,500 species worldwide are facing the threat of extinction. Presently, 12 percent of all bird species, 23 percent of all mammal species, 32 percent of all amphibian species and 31per cent of all gymnosperm species in the world face the threat of extinction.
So, the correct answer is 'Amphibians'.

  1. Rich in anthocyanin

  2. Endangered and threatened

  3. Tropical region

  4. Relatives of wild type animals

Show answer
Correct Option: B
Explanation:

The IUCN 'Red List of Threatened Species' is also known as the IUCN Red List or 'Red Data List'. It was founded in 1964, and it is the world's most comprehensive inventory of the global conservation status of biological species. The International Union for the Conservation of Nature (IUCN) is the world's main authority on the conservation status of species. 

A series of 'Regional Red Lists' are produced by countries or organizations, which assess the risk of extinction to species within a political management unit. The IUCN Red List is set upon precise criteria to evaluate the extinction risk of thousands of species and subspecies. These criteria are relevant to all species and all regions of the world. The aim is to convey the urgency of conservation issues to the public and policy makers, as well as help the international community to try to reduce species extinction.

IUCN (International Union for Conservation of Nature and Natural Resources) which maintains red data book has its head quarters at

  1. Kew, London

  2. Calcutta, India

  3. Morges, Switzerland

  4. New York, USA

Show answer
Correct Option: C
Explanation:

'The International Union for Conservation of Nature' (IUCN) is an international organization which is working in the field of nature conservation and sustainable use of natural resources. 

It is involved in data gathering and analysis, research, field projects, advocacy, lobbying and education. 
IUCN has a membership of over 1200 governmental and non-governmental organizations. 
Some 11,000 scientists and experts participate in the work of IUCN commissions on a voluntary basis. It employs approximately 1000 full-time staff in more than 60 countries. Its headquarters is in Switzerland. 

According to IUCN red List, what is the status of red panda (Ailurus fulgens)?

biology main natural resources classification of threatened species red data book methods of conservation

  1. Vulnerable species

  2. Critically endangered species

  3. Extinct species

  4. Endangered species

Show answer
Correct Option: D
Explanation:

Endangered species are those species which are on verge of becoming extinct. According to IUCN Red List, the red panda (Ailurus fulgens) comes under the list of endangered species. Due to deforestation, poaching, red pandas are at very high risk of being extinct. Its population has declined below 50% in last three generation.

Thus, the correct answer is option D.

If a certain plant species is not found in its wild localities even after repeated search, then it would be listed in which category in the "Red Data Book"?

biology main natural resources classification of threatened species red data book methods of conservation

  1. Extinct

  2. Endangered

  3. Vulnerable

  4. Rare

Show answer
Correct Option: A
Explanation:

There are nine categories present in the 'IUCN Red List' system: extinct, extinct in the wild, critically endangered, endangered, vulnerable, near threatened, least concern, data deficient and not evaluated. 

Classification into these categories occurs through a set of quantitative criteria that are based on biological factors that include the rate of decline, population size, the area of geographic distribution, and degree of population and distribution fragmentation. 
A species is listed as extinct in the wild when it is known only to survive in cultivation, captivity or as a naturalized population outside the previous range. A species is presumed extinct in the wild when exhaustive surveys in known and/or expected habitat, at appropriate times (diurnal, seasonal, annual), throughout its historic range have failed to record an individual.

Red data book is famous for 

biology main natural resources classification of threatened species red data book methods of conservation

  1. Extinct plants and animals

  2. Extinct plants only

  3. Endangered plants and animals

  4. Extinct animals only

Show answer
Correct Option: C
Explanation:

The 'Red Data Book' is the state document which is established for documenting rare and endangered species of animals, plants and fungi as well as some local subspecies, that exist within the territory of the state or country. This book provides essential information for studies and monitoring programmes on rare and endangered species and their habits.
