Keystone species - species which are like keystone in a building. You take out that & building will fall. Important for the whole ecosystem. If they go extinct, the system will not function as usual. Example beaver.
Flagship species - species which are important & we select them as an ambassador for our conservation programs. Mostly charismatic species. So that other species which are in that habitat can also be protected. The habitat can be protected. Example tiger.
Umbrella is similar kind of thing. We chose a species by whose conservation we can conserve others also.
Indicator species - species which are indicator of status of an ecosystem. It tells about the health of the ecosystem. For example river dolphin talks about health of river ecosystem.

If anybody wants to see how elephants sleep. PC BBC.
These are the elephants from China about which I shared recently. They are 15 elephants which have walked 500 km. The herd was seen resting near a village in Xiyang township after heavy rain slowed down its travels.

Complete details here.

bbc.com/news/world-asi…
Elephants have only two jobs; eat & sleep. They sleep heavily. They snore a lot.

Most of the time one among herd remains awake as a guard, mostly bull.

Now in India maize & monsoon is here. Elephants will stay on forest boundaries. In day they will sleep & in night will raid.

It will be repaired soon with protection this time.

Patrolling party reached first. Local range staff reached then. Mobile squad as backup. And vet team for care. All communication through RT for location & information. Four hours all went normal.

Do you know #elephant family is all women group. Made of #mother, #aunts, #grandmother & all other #ladies. Most of the times Male leave herd early. Kids are looked by all female elephants in herd, all are mothers. Grandmother makes all decision for the family. #Mothersday Image
Obvious that experienced matriarch should lead #elephant family. She has accumulated immense traits/wisdom due to her long life. Which comes handy in long journeys & dangers. Not true for all. In #Zebras pregnant lead the way as she needs more water. #Buffaloes decide mutually. Image
Males keep on joining & leaving herds. Well one of the accepted theory is. That males when they get young are pushed out from the herd/family by dominant female, also called as matriarch. To check the inbreeding. Which only shows elephants are highly intelligent. Image

Today is #WorldMigratoryBirdDay. When we read about them, we realise how least migratory humans are. Here is Himalayan griffon vultures, as sub adult they are migratory. We found many in sick condition & were able to revive 21. Here few stories about migration with Indian touch.
The real global tourist !! A Demoiselle crane tagged in Russia's Transbaikalia was spotted in Khinchan village in Jodhpur district in Feb. She traveled about 4,368 kms, the longest distance covered by the tagged migratory birds reported so far. While we were under lockdown.
While #Covid19 appeared. A female Common Crane was satellite tagged in March'20 near Nal Sarovar in India.

Named Vadla, migrated to breeding site in northern Kazakhstan and then returned exactly at site of her tagging on Migratory Bird Day, 10 Oct. By WII team.

That is how life starts. Millions of olive Ridley turtles started their journey from Odisha coasts as we are locked inside. Under close watch of forest department. One of the natures extravaganza. Sharing as received.
Each year millions of turtles reach to coasts with perfect synchronization for laying eggs, phenomenon is called as Arribada. New one comes put after 40-45 days.

It is said that mass nesting of #Turtles is a phenomenon as old as dinosaurs. 2/n
This mass nesting is a strategy to protect them from danger. To distribute the threat.

when turtles arrive on coast if they found disturbance they don't lay eggs. Some will dig the hole but if disturbance is there they will run away. Looking for suitable site & time. 3/n

Tribute to the man who knew #infinity on his 101st death anniversary. Srinivasa Ramanujan, pioneer in mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series & continued fractions. He lived only 32 years & left the world in 1920.
Son of a clerk from erode, who stunned the world with his mathematics prowess.

Later became one of the youngest Fellows of the Royal Society & only the second Indian.

And also the first Indian to be elected a Fellow of Trinity College, Cambridge.
Even in that short life independently compiled nearly 3,900 results. Most were novel. Interesting thing his many works are still attracting mathematicians.

He worked in isolation many a times, as a result he also proved things which were already done by others at that time.
