SALIM ALI
Sálim Moizuddin Abdul Ali (12 November 1896 – 20 June 1987)
was an Indian ornithologist and naturalist. Sometimes referred to as the
"birdman of India", Salim Ali was among the first Indians to conduct
systematic bird surveys across India and his bird books helped develop
ornithology. He became the key figure behind the Bombay Natural
History Society after 1947 and used his personal influence to garner
government support for the organisation, create the Bharatpur bird
sanctuary (Keoladeo National Park) and prevent the destruction of what
is now the Silent Valley National Park. He was awarded India's second
highest civilian honour, the Padma Vibhushan in 1976.

Herbivores + light = more plant biodiversity in fertilized grasslands
Research on six continents shows that it all comes down to the light
March 10, 2014
Fertilizing by humans and plant-eating by herbivores can combine
to benefit plant biodiversity--if enough light still reaches the ground,
according to results of a study by ecologists Elizabeth Borer and Eric
Seabloom of the University of Minnesota and colleagues.The findings,
published this week in the online edition of the journal Nature, are
important in a world where humans are changing both where herbivores
are found and the supply of plant nutrients such as nitrogen, phosphorus
and potassium.
