Amazing week at

with
@CNWWs
team and an amazing group. We were cold, so drank coffee, mulled wine, and ate poutine. We did science, on hockey, ants, cancer, random networks and science itself. We went a toboggan race, met nuns and caught a thief.
See you at

I would like to thank everyone who has played a major part in making me who I am today and specifically, standing by me throughout my Ph.D.: my mentors from over the years, collaborators, grad school community, my friends, and above all, my family!! Thank you all for being there!

Excited about our new preprint where we use interactions among microbial guilds to predict methane oscillations (methane hazes) ~2.5 billion years ago.
Major find: Complex interplay between oxygen and resource input levels might have caused these hazes!
Now the books: I had many favorites this year.
For fiction, I am glad I explored a lot of new Indian and non-Anglo writers. I really loved 'Homegoing' by Yaa Gyasi, and 'Rumours of Spring' by
@FarahBashir
. Among graphic novels, 'Blankets' by Craig Thomson was my favorite. (2/5)
My first book of this year was My Husband & Other Animals
@JanakiLenin
I loved it! It was a set of free-flowing,well-written recollections interspersed with adventures and animals-things I adore! What I loved more, was it introduced me to 'Watchers at the Pond' by F Russell (1/n)
We designed a model with a continuous domain representation that generalized the speciation and the interactions of microbial systems to incorporate evolutionary dynamics. Colouring the microbes according to species leads to some dazzling visuals:
"Quite interesting" is the nicest thing anyone has ever said to me. Love you too!
P.S. The study is not quite as dumb as it sounds, see with

@_jgyou
In this work, we primarily look at antagonistic interactions among microbes through an agent-based model, which incorporates higher-order interactions, a variety of mutational regimes and a continuous species space.
We then track the spatiotemporal dynamics of these populations.

I'm very excited to share that we have a new paper out on plant-insect interactions! We found some pretty interesting patterns using modern leaves collected using paleobotanical methods.
@anshuswain

Using this novel representation, we can understand interdependencies and intricacies of insect damage and quantitatively compare them at various scales (taxa and assemblage) in a more holistic way.
Please do check it out!

We find that community formation time (CFT: time to stability) can delineate different spaces of spatial heterogeneity and diversity dynamics in model runs, but itself is not predictable using model parameters - making it an important emergent property of the system.
This work was done in collaboration with Levi Fussell from University of Edinburgh, and was possible only because we met through

Through the lens of non-cyclic dominance (i.e., where a single species is not dominant in any specific ecological trait), we link the trajectory of community assembly to both spatial heterogeneity and diversity dynamics, thereby providing new perspective on eco-evo dynamics.
The acoustic fingerprints of degradation history were conserved across replicate recording locations, indicating that
#soundscapes
may offer a robust, taxonomically
#inclusive
solution for digitally tracking changes in acoustic community composition over time!
We find that the emergent 24-h patterns of acoustic activity differed between logged and burned forests and that large and sustained shifts in acoustic community assembly after multiple fires.
Such a great experience! Wrote a cool paper, made new friends/colleagues, hung out at

We propose a new way to look at possible bias in these assemblages.
We show that clustering analyses of these interactions reveal possible ecological categories, and use Agent-based models to map these categories to known ecological patterns.

Higher number of interactions on a given topic created increased levels of interest and more engagement among the students, resulting in more term-end projects on that specific topic. (4/4)
Time lags over which geysers influence each other's activity vary from hours to weeks, and the lags at which the strongest pairwise impacts occur are substantially longer during winter, perhaps due to slower recharge during that season. (4/6)
Geyser separation distance matters! Nearby geysers had stronger effects on focal geysers than did geysers located farther away. These effects were stronger on short (5–10 min) and long (5–10 days) timescales compared to intermediate scales. (3/6)
Our findings also contradict expectations from Acoustic Niche Hypothesis that animal communities in more degraded habitats necessarily occupy fewer acoustic niches. Instead, we found that aboveground biomass was not a consistent proxy for acoustic

Interactions with more people have the potential to raise one’s performance, even though interactions with fewer people did not mean lower performance, which may be more individually driven. Also more interaction with the same people didn't cause any differences.

For science/nat.his., I loved 'Braiding Sweetgrass' by Robin W Kimmerer, 'How the Earth Turned Green' by Joseph Armstrong, 'Beasts before us' by

We found that over the timeline of the semester, the average number of people that one individual interacted with (average degree) first increased and then decreased but they interact more (sum of edge weights increases) with a specific set of people towards the end.
(2/4).
Focusing on the ratio of self-effects to outside effects allows characterization of the degree of insulation experienced by each geyser, and identification of those geysers whose reservoir complexes appear to be more strongly connected to the groundwater flow system. (5/6)
We find divergent patterns of acoustic space occupancy between
#logged
and
#burned
forests. We see huge reorganization in acoustic community after multiple fires; sound networks were quieter, more homogenous, in forests burned multiple times than in logged or once-burned forests.
