Introduction To Chinkara
The Chinkara, or Indian gazelle, (Gazella bennettii) is a
species of gazelle found in south Asia.
Characterized by a sandy, yellowish and red colored fur with a pale
white ventral region.
They have straight horns with prominent rings and tips that are
slightly out-turned
Horns are found on both males and females, although they are
relatively shorter in females. Usually male weighs around 23kgs & female weighs around 15-
18kgs.
It is preyed upon by leopards and dholes, and was a common prey
item of the Asiatic cheetah.
Scientific Classification of Chinkara
Kingdom: Animalia
Phylum:Chordata
Class: Mammalia
Order: Artiodactyla
Family: Bovidae
Genus: GazellaSpecies:
bennettii

Behavior of CHINKARA
Shy animal.
Avoids human habitation
Stay as far from human settlement as
possible.
Indian Gazelles can run at great speeds
ranging from 50 to 60 Kms.
Roaming alone.
Or in small groups, up to 4 animals.
Survive without water for days at a stretch.
Common habitats of Chinkara
Distribution
It lives in grassland, desert areas and rainforest in India, Bangladeshand parts of Iran and Pakistan.
Widely distributed in India , being present in 9 states:
Rajasthan
Madhya Pradesh
Gujrat
Uttar Pradesh
Haryana
Bihar
Karnataka
Andhra Pradesh
Maharashtra
Groups of Chinkara never exceeded beyond 6 individuals in eitherseason.
Diet and Feeding Of Chinkara
Diet in Wild:
Grasses
Green leaves
Buds of flowers & fruits such as pumpkins and melons.
Majority of their metabolic water intake comes from the
vegetation they consume.
It can go without water for long periods and can get
sufficient fluids from plants and dew.
Mating Behaviour
Do not have specific time for breeding.
Though Autumn and Spring season are preferred as mating
period.
Mating System : Polygynandrous (promiscuous).
Mating begins as a male gazelle touches the under parts of a
female gazelle with a stiff leg, called “laufschlag”.
When complete, copulation ensues.
Gestation lasts for 5-6 months and females give birth to 1 or
2 young ones.

Phylogenetic tree of Chinkara

Phylogenetic tree of sub species Antilopinae
Chinkara (Indian gazelle)
The genetic adaptation of Chinkara:
The Indian gazelle is extremely fast & the leopard is
even faster. These traits are adaptational characteristics
or behaviors that give a gazelle an edge in the struggle
for survival.
Also by following the two stages of adaptation- random
variation & natural selection , the Leopard has become
faster.
Random variation results from sligth genetic difference
both in case of Leopard & Chinkara.
Genetic Diversity of Chinkara
Genetic Diversity of Chinkara (cont..)
Both of their offspring will have the same gene, that
influence the speed. As the population of leopard become
faster, there is now a selection pressure on gazelles to
become more & more faster.
Therefore we may say that the Chinkara have become faster
through evolution & the gene it carries inside will survive as
well & will be transmitted to the next generation.
As generation pass, good gene become more frequent in
gene pool of Indian gazelle.

Chromosomal Evolution in Gazelles
The chromosomes of nine gazelle species and two other
antilopinae species (antidorcas marsupialis and antilope
cervicapra) were prepared from fibroblast cultures.
G- and C-band karyotypes were constructed, and when
possible, autosomal arms were numbered according to
the cattle standard karyotype.
Diploid chromosome numbers ranged from 30 to 58 .
Therefore evolution in this genus could have occurred
mainly by speciation following monobrachial
homoeology of centric fusions.
Chromosomal Evolution in Gazelles (cont.)
X to autosome translocations were common in
the whole genus.
This phylogenetic reconstruction confirms most
of the taxonomic relationships obtained by
morphological analyses for this group of
species including Gazella bennetti..
Comparative Genetics
Diversity in total number of chromosome of Chinkara
with other gazelle species:
The interesting feature of other species in genus gazelle is that,
their widely varying chromosome number.
In CHINKARA (Gazella bennetti) 2n=49 (female) 52 (male)
In DORCAS GAZELLE 2n= 30 (female) 31 (male)
In THOMSON’S GAZELLE 2n=58
In SAUDI GAZELLE 2n=47(female) 51(male)
Therefore this is one of the major GENETIC DIVERSITY of
Chinkara with other species around the world, though they belong
to the same genus.

Interesting Facts
In 1998, an Indian
film star, Salman
Khan, was charged
with hunting
Chinkara.
A young / baby
of a Indian
gazelle is called
a 'calf'.
The alert nature of
Chinkara helps
them to get hunted
from the predators
like Hunters,
Cheetah, etc.
Indian Gazelle
(Chinkara) is
known as the
state animal of
Rajasthan in
India.
In 1994 the species was considered
vulnerable.
In 1996 Gazella bennettii was
considered a species of lower risk.
Major Threat(s) of Chinkara
Indiscriminate hunting and habitat loss.
Hunted for meat and to a lesser degree for trophies.
Habitat loss through-
Overgrazing
Conversion to agriculture
Industrial development.
Conservation Status of Chinkara
Considered a species of least concern by the International Union for Conservation of Nature (IUCN).
Indian country has enacted laws against killing of Gazelles.
In the North Western parts of the Indian country, people called as Bishnoi community protect this animal for their religious reason.
Conservation status
Least Concern (IUCN 3.1) (A Bishnoi priest feeding a Chinkara)
Conclusion
Chinkara is a slender and graceful deer.
Although from IUCN red data book it has been found
that Gazella bennetti (Chinkara),belongs to the category
of least concerned but it is our duty to be concerned
about the fact of conservation of Chinkara in India
because not only Leopard is the enemy of Chinkara, also
human being are major threat to them.
Let us save Chinkara from extinction.
