Question 1
1 / -0

The map gives the former and present distribution. Which one of the following it could be?

A
Wild Ass

B
Nilgai

C
Black Buck

D
Lion

Solution

Ghudkhur, Khur, Indian onager or the Indian Wild Ass is a subspecies of the onager which is native to Southern Asia. It is categorized as an endangered species of India. The specialty of this animal is that it is one of the fastest of Indian animals, with a speed of 70 – 80 km. per hour and thus it can easily outrun a jeep. Its habitat destruction due to salt activities is causing a decrease in its population. Now, the species is limited to Rann of Kutch (India).
So, the correct answer is 'Wild Ass'.
Question 2
1 / -0

Latitude range with maximum species diversity is

A
$$23.5^0 N -66.5 ^0 N $$

B
$$23.5^0 S -66.5 ^0 S $$

C
$$23.5^0 N -23.5 ^0 S $$

D
$$66.5^0 N -66.5 ^0 S $$
Solution
Latitudinal gradients of biodiversity are biogeographic patterns that quantify the ways in which taxonomic, phylogenetic, functional, genetic, or phenetic biodiversity change with the latitudinal position on the surface of the earth.
Species richness, or biodiversity, increases from the poles to the tropics. So the latitude range with maximum species diversity is the equator region, which is option C.
Question 3
1 / -0

Discovery of new species has recently picked up due to project _________.

A
Species 2000

B
Global Biodiversity Information Facility

C
Agenda 21

D
Both A and B

Solution

A) Species 2000 is an autonomous federation of taxonomic database custodians which involves taxonomists in the whole world.
B) The Global Biodiversity Information Facility is an international organization which basically focusses on making scientific data on biodiversity available on the internet.
C) Agenda 21 is an action idea of the United Nations which addresses sustainable development.
Discovery of new species has recently picked up due to project Species and 2000 and Global Diversity Information Facility.
So, the correct answer is 'Both A and B'.
Question 4
1 / -0

An easily disturbed ecosystem which can recover after some time, after the stoppage of damaging factor is of

A
Low stability and high resilience

B
High stability and high resilience

C
Low stability and low resilience

D
High stability and low resilience

Solution

So the correct option is A.
Question 5
1 / -0

India constitutes _______ percent of the world's land area and contributes _______ percent of the global species diversity.

A
1.0, 5.5

B
5.5, 1.0

C
8.1, 2.4

D
2.4, 8.1

Solution

Although India has only 2.4 percent of the world's land area, its share of the global species diversity is an impressive 8.1 percent.
Question 6
1 / -0

A graph of species richness vs area on log-log axes is?

A
Linear

B
Sigmoidal

C
Oscillatory

D
Parabolic

Solution

The species-area relationship or species-area curve describes the relationship between the area of a habitat and the number of species found within that area. Alexander Von Humboldt observed that within a region, species richness increased with increasing area, but up to a limit. The relation between species richness and area for a wide variety of taxa (plants, birds, fishes) turn out to be the rectangular hyperbola.
On a logarithmic (log) scale, the relationship is a straight line (linear) and is given by the following equation:
log S = log C + Z log A,
where, log S= species richness, Z= slope of the line, A= area, C= y-intercept.
Question 7
1 / -0

Identify different types of diversity denoted by 1, 2 and 3 in the given figure.

A
1 - Alpha diversity; 2 - Beta diversity; 3 - Gamma diversity

B
1 - Gamma diversity; 2 - Alpha diversity; 3 - Beta diversity

C
1 - Gamma diversity; 2 - Beta diversity; 3 - Alpha diversity

D
1 - Beta diversity; 2 - Alpha diversity; 3 - Gamma diversity
Solution
The ecological biodiversity can be measured at three levels of the community. The three levels include the Alpha diversity, Beta diversity and Gamma diversity.
Alpha diversity represents the number of species in a particular community, and it is used to compare the number of species within the community.
Beta diversity is used to compare the number of species between two communities.
Gamma diversity refers to the sum of alpha diversity and beta diversity. It is used to measure diversity as a whole within a large area.
In the given figure, 1 represents Beta diversity as it is showing the comparison between two communities. Alpha diversity is denoted by 2 as it includes a single community. Gamma diversity is denoted by 3 as it contains the whole geographical region including alpha and beta diversity. Thus, the correct representation is '1-Beta diversity; 2-Alpha diversity; 3-Gamma diversity'.
Question 8
1 / -0

Consider the following statements regarding project Brahma?
1 .It aims to document ideas on education, environment and society related and relevant to India.
2 . www.biodiversityofindia.org is a website related to the project.
3 . It is an open- source community driven project.
Which of the statements given above is / are correct?

A
Only 1

B
2 and 3

C
1 and 3

D
All of the above
Question 9
1 / -0

On a logarithmic scale, the species area relationship is a straight line described by the equation log S = log C + Z log A.
What does S, C, Z and A represent in the given equation? Select the correct answer from the codes given below.
Species richness = 1
Slope of the line = 2
Y- intercept = 3
Area = 4

A
1 - C; 2 - S; 3 - Z; 4 - A

B
1 - S; 2 - Z; 3 - C; 4 - A

C
1 - Z; 2 - S; 3 - C; 4 - A

D
1 - A; 2 - C; 3 - S; 4 - Z

Solution

The relationshipbetween species richness and area is rectangular hyperbola for a wide variety of taxa whether they are birds, bats, freshwater fishes or flowering plants and the equation can be given as S = $$CA^z$$.
Question 10
1 / -0

According to, May's global estimates how many species of plants and animals, respectively, are yet to be discovered and described from India?

A
50,000 and 90,000

B
3,00,000 and 90,000

C
3,00,000 and 1,00,000

D
1,00,000 and 3,00,000

Solution

If we accept May's global estimates only 22% of the total species have been recorded so far. If May's proposal for discovery of new species is accepted then there are probably more than 1,00,000 plant species and more than 3,00,000 animal species yet to discovered and described.
So, the correct answer is option D.
