प्रकृति: रक्षति रक्षिता ! Mangrove forest after a cyclone. The line of defense after a cyclone.
#Mangrove; not only home for various species but also a tool against #Disaster. Tropical country like India, with densely populated 7500 km long coastline, will be effected by cyclones more due to #ClimateChange. This salt tolerant species acts as a shield against cyclones. 2/n
So how it works. Reposting my old tweets. Mangroves create a maze & dense habitat. With species which are salt tolerant & special adaptations. They act like buffer & consume the winds & energy. So after passing the storms get dampen. 3/n
These are called as #pneumatophores. Mangrove ecosystem has high amount of soil moisture & salt. To take air trees here build special Aerial #roots. Which come out from ground & can grow upto 30 cm. Then air is supplied to all parts of a tree. #Natural filters. 4/n
Now as thick this #mangrove belt is, more effective it will be in resistance to #cyclones & other #disasters.

They provide habitat to numerous wildlife species which makes the system healthy & balanced. 5/n
#Mangrove #ecosystem is not static. It is dynamic, keeps changing. With size variety of #landscape increases.

You see here a small #grassland inside mangrove belts. On one side destruction & on other creation. 6/n
Habitat to not only herbivores but also hypercarnivorous apex #predators like this. One of the largest crocodilian #species on #planet, whose size can go upto 6 metre in length. A salt water crocodile. This one basking in sun at Sunderban. A stable & balanced system. 7/n
Enough reasons to protect them.

All pictures & information are mine. During my exploration trips. All are free to use and publish pictures and information in whatever manner they want to. n/n

It was May 10, 1901. The central hall of the Royal Society in London was jam-packed with famous scientists. Everyone seemed to be curious to know how Sir JC Bose’s experiment will demonstrate that plants have feelings like other living beings and humans. He did it wonderfully.1/n
He demonstrated it wonderfully with his invention called as Crescograph.

So rightly called as First Modern scientist of India.

Sir JC Bose was the first Indian to be appointed Professor of Physics in the Presidency College. 2/9
His appointment was strongly opposed by britishers.

In those days one can be appointed to Imperial Education Service only through nomination, unlike IAS.

And he was appointed only when Lord Ripon personally intervened. 3/n

And all the five jungle cat cubs were saved. Found by farmers during harvesting in a field.
All were so small that they could not have been survive without mother.

So we decided to reunite them with mother.

The area was cordoned off. Where they were found villagers decided to stop harvesting for the time being.
Camera traps were established in the area carefully.

Teams and villagers stationed for the night near the location. So that they can be monitored and no disturbance occur.

In 1930, anticipating Nobel Prize, CV Raman bought two tickets to Stockholm, other for wife, as early as September, 3 months early.

His conviction was not misplaced; he was decorated with the Nobel Prize for Physics that year for his path-breaking work. #BirthAnniversary
Raman was also the first Non white to get Nobel Prize in science. It took merely Rs. 200 to make this discovery & now millions of rupees. University of Cambridge offered him a Professor’s job. He rejected & later appointed as 1st Non British Director of IISc Bangalore in 1933.
During WW2 tried best to bring some scientists to work in #IISc, including Niel Bohr, Heisenberg, Pauli. Max Born spend some time here.

CV Raman studied Science, but got selected in Indian Financial Service. Was in good position. But later returned back to world of science.

On this day in 1730, 363 Bishnois from Jodhpur were killed in Khejarli, when objected to felling of Khejri trees by the king. Day is celebrated as #ForestMartyrsDay. Scores of ground staff & officers have laid down their lives in protecting the ecological security of country.
When teams came to cut Khejri trees summons were sent to 83 Bishnoi villages.

The cry was “सिर साटे रुख रहे तो भी सस्तो जाण” which means even if head goes to save a tree then also it is worth.

With this 363 Bishnoi’s martyred to save trees led by Amrita Devi Bishnoi. 2/n
To commemorate the day of this 'bishnoi massacre' India observe this day as 'Forest Martyrs Day'.

The modern Chipko movement was spread in years & is considered as eco-feminist movement, led by women. And a movement for ownership of resources based on gandhian principles.
