Tree crickets chew holes in leaves, making megaphones or "baffles" to attract mates. I am studying the evolution of baffling in my PhD. A bit of phylogenetics, a bit of citizen science. Follow the link to my new project on @inaturalist
inaturalist.org
This project aims to collect data on “baffling” behaviour in tree crickets (subfamily: Oecanthinae). Baffling is a strategy used by males to amplify their songs. They do so by using their substrate,...

(4/4) It is freely available from this link- https://t.co/RCr7SFtwee This paper is really special to me as I have always wanted to do some research on snakes and this is my first snake paper 😊😊❤️ The amazing snake photos are by Damien Esqueree.

The evolution of thermoreception in animals, particularly that of infrared (IR)-sensing pits in boas, pythons and pit vipers, is a fascinating area of sensory ecology. While numerous studies have...

(3/4) We find that these pits likely act as "Key Innovation" and help these snakes to exploit the arboreal environment and warm-blooded prey (like rodents, birds). The paper got published in the journal Proceedings of the Royal Society B.

New publication on heat-sensing pits in pythons and boas!
(1/4) New publication alert!!! Certain species of snakes have prominent heat-sensing pits on their face, like this gorgeous Green tree python! But under what circumstances do these pits evolve? And what benefit do they provide? Photo credit - @DamienEsquerre

My two cents on evolution, academia and everything in between.
What does it really mean to be a postdoc? Radio PDF is back with a new season, tackling the realities of postdoctoral life. Our inaugural episode features @maitreyasil , who shares his experiences navigating his career path, detailing the obstacles he's faced and the key

2025 started great it seems. Our manuscript of sequencing whole genomes of mammals from blood sucking insects is out. We show that blood sucking insects can be a great way of sampling certain mammals from population genomic investigations. (1/n) https://t.co/1K7bMz1V2P

You're doing a masters degree in life sciences and you want to contribute to Indian wildlife and conservation. Career in academia isn't the only option. Perhaps a conversation with an Indian forest officer will help you understand new avenues and how you can contribute to Indian

Our work on population genomics of Asiatic elephants is finally out (with a few errors in the title page). We find that there are potentially five populations of Asiatic elephants in India. We find a signature of serial colonization by elephants from north to south. 1/n
📢NEW! @uramakri @Anubhab_Khan & team have uncovered five distinct elephant populations across India, revealing more diversity than previously known. This latest study uncovers new insights into genetic history of India’s #Asianelephants🐘 Read here: https://t.co/TL7dp5oU8O

@davidraju2007 @VivekCyriac @AniruddhaM11371 @skinkomaniac @vidishakulkarni The skink turned out to be Lankascincus fallax, a species supposedly endemic to Sri Lanka! We spoke about the occurrences in detail and speculate how it might have arrived at the Kerala coast in the first place.
