Nandan-Kanan zoo is known for 

 

  • Hippo

  • Nilgiri Tahr

  • White Tiger

  • Whale

The most important cause of loss of biodiversity today is:

  • habitat loss and fragmentation

  • over-exploitation

  • alien species invasions

  • co-extinctions

The Earth Summit was held in Rio de Janeiro in:

  • 1987
  • 1990
  • 1992
  • 2002

When a threatened plant needs urgent measures to save it from extinction, the desirable approach is

  • in-situ conservation
  • ex-situ conservation
  • cryopreservation
  • biopreservation

The search for previously unknown compounds in organisms that have never been used in traditional medicine is known as:

  • Biopiracy

  • Bioprospecting

  • Molecular pharming

  • 4 Bioremediation

Loss of biodiversity may lead to all except:

  • decline in plant production
  • increased resistance to environmental perturbance
  • increased variability in water use
  • increased variability in pest and disease cycle

Which of the following is not a reason that accounts for greater biodiversity of tropics?

  • availability of more solar energy

  • more niche specialization
  • more time for species diversification
  • large seasonal variations in environmental factors

The greatest biodiversity on the earth is found in

  • African grasslands
  • Amazonian rain forest in South America
  •  Western Ghats in India
  •  Nile delta in Egypt

Biodiversity loss is now one of the world's most pressing crises. The primary reason for this is:

  • we cannot do anything about it
  • we are not responsible for this loss
  • we still do not know its entire extent
  • it is affecting only the developing countries

The main difference between "Sixth Extinction" and the previous five extinctions is that the sixth extinction:

  • is mainly occurring on islands
  • is mainly affecting plants
  • is occurring at a faster rate
  • does not involve human activities

Which of the following does not contribute to the species diversity of the tropics?

  • Predictability

  • Predation

  • High productivity

  • Spatial homogeneity

The relation between species richness and area for a wide variety of taxa on a logarithmic scale is a:

  • rectangular hyperbola

  • straight line

  • sigmoid curve

  • sine curve

The hot spots of biodiversity conservation are characterized by:

  • High endemicity and high threat of extinction
  • Low endemicity and high threat of extinction
  • High endemicity and low threat of extinction
  • Low endemicity and low threat of extinction

Which of the following has maximum global biodiversity?
  • Angiosperms
  • Algae
  •  Lichens
  • Mosses

What is applicable to both Lates niloticus and Lantana camara ?

  • They are on the verge of extinction due to over-exploitation by humans.

  • They are alien species that became invasive in certain environments causing threat to indigenous biodiversity.

  • They are mutualists and likely to undergo co-extinction in recent future.

  • They are keystone species and are vital to the stability of tropical ecosystems.

The most effective means of conservation of biodiversity is:

  • Remove predators
  • Preserve habitats
  • Vaccinate against disease
  • Census the species during breeding season

Alexander von Humbolt described for the first time 

  • ecological biodiversity

  • law of limiting factor

  • species area relationships

  • population growth equation 

Presence of plants arranged into well defined vertical layers depending on their height can be best seen in

  • tropical savannah

  • tropical rain forest

  • grassland

  • temperate forest

Which one of the following is related to Ex-situ conservation of threatened animals and plants?

  • Wildlife Safari parks

  • Biodiversity hotspots

  • Amazon rainforest

  • Himalayan region

The region of biosphere reserve, which is legally protected and where no human activity is allowed is known as

  • () core zone

  • () buffer zone

  • () transition zone

  • () restoration zone

How many hotspots of biodiversity in the world have been identified till date by Norman Myers?

  • 17

  • 34

  • 25

  • 43

Which of the following is correctly matched?

  • Arenchyma               -   Opuntia

  • Age pyramid             -  Biome

  • Parthenium hysterophorus - Threat to biodiversity

  • Stratification             - Population

Red List contains data or information on

  • all economically important plants

  • plants whose products are in international trade

  • threatened species

  • marine vertebrates only

Which of the following National Parks is home to the famous musk deer or hangul?

 
  • Keibul Lamjao National Park, Manipur

  • Bandhavgarh National Park, Madhya Pradesh

  • Eaglenest Wildlife Sancturay, Arunachal Pradesh

  • Dachigam National Park, Jammu and Kashmir

Which is the National Aquatic Animal of India?

 
  • 1 River dolphin
  • 2. Sea-horse
  • 3. Blue whale
  • 4. Gangetic shark

The species confined to a particular region and not found elsewhere is termed as

  • keystone

  • alien

  • endemic

  • rare

Cryopreservation of gametes of threatened species in viable and fertile condition can be referred to as

  • in situ conservation of biodiversity

  • advanced ex situ conservation of biodiversity

  • in situ conservation by sacred groves

  • in situ cryo-conservation of biodiversity

An example of ex situ conservation is 

 

  • National Park             

  • Seed Bank

  • Wildlife Sanctuary       

  • Sacred Grove

The organisation which publishes the Red List of species is

  • ICFRE  

  • IUCN  

  • UNEP  

  • WWF

Which of the following represent maximum number of species among global biodiversity ?

  • Algae

  • Lichens

  • Fungi

  • Mosses and ferns
