Biodiversity and conservation practice · Mixed difficulty

Choose the mismatched pair w.r.t the loss of biodiversity.

Rivet-popper hypothesis was given by

Which of the following is correctly matched?
I. Alpha diversity – Number of species in a given habitat
II. Genetic diversity – Variation of the genes within species
III. Beta diversity – Diversity of the habitat in the whole region
IV. Species diversity – Product of the species richness and evenness

Biodiversity is affected by

All of the following have common cause of their extinction, except

A historic convention on biological diversity held in Rio de Janerio in 1992 is known as

Which one of the following possesses a very large number of endemic amphibian species?

How many mangroves species are founds in marine bio diversity of India?

There is a forest next to Raju’s village which is a natural habitat for an endangered species of lotus. The Government plans to develop a highway through the forest which will cause disturbance in the habitat and may lead to exctinction of the endangered species. Being an environmental activist, what must have Raju suggested the Government in order to save the species as the highway project is also important for the development of the village?

What is the sustainable use of resources?

Assertion (A): Tropical regions are more diversity rich in comparison to temperate areas.

Reason (R): Availability of more solar energy directly affects the presence of more species in these areas.

Modern ex situ conservation includes

Since the origin and diversification of life on earth, how many episodes of mass extinction of species have occurred till date?

Jim Corbett National Park protects

The animals which are in danger of extinction of which is also possible are known as

Assertion: Biodiversity hotspots are the regions
which possess high levels of species richness,
high degree of endemism and no loss to habitats.
Reason: Total number of biodiversity hotspots
in the world is 32 with two of these hotspots
found in India.

Assertion: In case, a species becomes extinct,
the plant and animal species associated with it
in an obligatory way also become extinct.

Reason: When a host fish species becomes
extinct, its unique assemblage of parasites also
become extinct.

Assertion: Communities that comprise of more species tend to be more stable.
Reason: A higher number of species results in less animal variation in total biomass.

One of these is not concerned with wild life conservation.

Three levels of biodiversity are

If log A = 4, Z = 0.3 and logC = 0.8, what is log
S?

Which of the following is a correct representation of the species diversity of birds in the regions mentioned?

Read the following statements.
I) Gamma diversity is the diversity of the entire landscape.

II) species diversity increases as we move away from the equator towards the poles.

III) Genetic diversity decreases with environmental variability.
IV) Western Ghats have a greater amphibian species diversity than the Eastern Ghats.

Which among the above are true?

In the species area relationship, ‘S’ represents

“Nature’s biological library is burning even before we catalogued the titles of all the books stocked there” suggests the concept of

In situ strategies includes
I. National parks
II. Wildlife sanctuaries
III. Biosphere reserves
IV. Sacred forests/Lakes
Choose the correct option

Number of wild life is continuously decreasing. What is the main reason of this?

Assertion: If the species-area relationships are
analyzed among very large areas like the entire
continents, the value of Z i.e., slope of line lies
in the range of 0.1 to 0.2.

Reason: The value of Z i.e., slope of line of
species area relationships lies in the range of 0.6
to 1.2 when analysis is done among small areas.

What is the main cause for the extinction of some species in tropical forest?

The largest brackish water lagoon in Asia is:
