Physiological ecology of tropical forests
Clear and unequivocal climate emergency
A statement endorsed by more than 11,000 scientists from 153 countries, "tells it like it is", and
warns of a CLEAR and UNEQUIVOCAL climate emergency facing planet Earth. They recommend deep lasting changes that are urgently needed to check population growth, fossil fuel use, forest destruction and meat eating. Without these, the study says that the world is facing "untold human suffering"!
Congratulations to Shatarupa who successfully defended her Doctoral thesis:
The consequences of intra-population variation in sex organ positions on herkogamy and reciprocity, and consequently reproductive success in species exhibiting style-length polymorphism.
Record temperatures in Kuwait and Karachi
The World Meteorological Organisation recently announced that two recent temperature readings have been accepted as among the hottest recorded on earth.
These records of 53.9 degrees and 53.7 degrees Celsius came from Mitribah, Kuwait, on July 21, 2016, and Turbat Pakistan, on May 28, 2017, respectively. These represent the highest temperatures recorded in the last 76 years and the highest ever in continental Asia.

Alarming rates of plant extinctions - especially from the tropics
Rates of plant extinctions were estimated at an alarming rate of 500 times greater than would be expected due to natural causes alone! Almost 600 plants have gone extinct since 1900. Trees and shubs have seen relatively greater rates of extinction as have flora from tropical regions, including India. These numbers are likely to be underestimated, and these high extinctions will have important negative consequences for most other organisms, ecosystems and also on human well-being.

17th - 22nd September, PEEP-in, 2018, Sirsi, Karnataka
A first of its kind in India! This intensive 6-day workshop for training early career researchers in plant ecophysiological and forest monitoring techniques was held on 17–22 September 2018 in Sirsi, Karnataka. A total of 26 participants were selected from over hundred applicants, and included researchers from 18 institutes across 11 states. These participants ranged from students who had recently finished their Masters degrees, to PhD scholars, post-doctoral fellows, and new faculty.
