Manja, or the glass-coated string used for flying kites, not only poses threat to humans, animals and birds but also to trees. A study by the country’s oldest botanical garden has revealed that it poses a great threat to trees. But how can a snapped string struck in a tree kill the tree? Apparently, it does so by allying with the creepers in the garden.
A research paper by three scientists of the Acharya Jagdish Chandra Bose Indian Botanic Garden, located in West Bengal’s Howrah district, illustrates in detail how the manja, in collusion with climbers, does the damage. “The abandoned, torn kite strings act as an excellent primary supporting platform for the tender climbers, giving easy passage to reach the top of the trees. Lateral branches from the top of the climber and other accessory branches from the ground reaches the top taking support of the first climber, completely covers the treetop, thus inhibiting the penetration of sunlight,” says the research paper.

Genetic variation is the cornerstone of evolution, without which there can be no natural selection, and so a low genetic diversity decreases the ability of a species to survive and reproduce, explains lead author Yoshan Moodley, Professor at the Department of Zoology, University of Venda in South Africa.
Two centuries ago, the black rhinoceros – which roamed much of sub Saharan Africa – had 64 different genetic lineages; but today only 20 of these lineages remain, says the paper. The species is now restricted to five countries, South Africa, Namibia, Kenya, Zimbabwe and Tanzania. Genetically unique populations that once existed in Nigeria, Cameroon, Chad, Eritrea, Ethiopia, Somalia, Mozambique, Malawi and Angola have disappeared. The origins of the ‘genetic erosion’ coincided with colonial rule in Africa and the popularity of big game hunting. From the second half of the 20th century, however, poaching for horns has dramatically depleted their population and genetic diversity, especially in Kenya and Tanzania.
Question 6: What is important for evolution?
a) Genetic variation
b) Large population
c) Mixing of species
d) Survival of the fittest
Question 7: Sub Sharan Africa has lost how many black rhino genetic lineages in 200 years?
a) 64
b) 20
c) 44
d) 30
Question 8: Genetically unique black rhinoceros has been lost in all of the following countries, except?
a) Tanzania
b) Nigeria
c) Chad
d) Malawi
Question 9: From the second half of the 20th century what has caused a dramatic fall in black rhinoceros population?
a) poaching
b) colonial rule
c) big game hunting
d) fall in genetic diversity
Question 10: Genetic diversity is proportional to __________.
a) species population
b) the ability of a species to survive and reproduce
c) inbreeding
d) extinction
