Super cool! Excited to see this

Fredrik found that we didn't have a mathematical description of how salinity affects growth rate. We came up with two and show they accurately capture the salinity response of hundreds of phytoplankton strains - and other taxa as well. We can now model how salinity shapes population dynamics! 🌊

Of all the harm this administration has done to US science, today's proposed changes to the way federal grants are awarded and administered is the most damaging yet. The text of the federal register document is impenetrably tedious by design, so here's an excellent summary of what it says.

NSF LTER program “archived”. LTER=“Long Term Ecological Research”. This program has been incredibly successful, incredibly frugal for what they accomplish, and…of course…targeted by evil know-nothings. My heart is breaking.

We propose that ‘antifragility’, coined by Nassim Taleb, is a great high-level concept for ecologists of all kinds for parsing and communicating the effects of environmental variability. An antifragile property benefits from variability. We explore its use in two mathematical models. (2/4)

A timely reminder for those who think about population growth and dynamics, ecologists/evolutionary biologists or otherwise, that it is extremely important to be aware of how those ideas are misused when applied to human populations, especially by nations and individuals with privilege and resources

Mridul K. Thomas@mridulkthomas.bsky.social

Paul Ehrlich is remembered for a bet that he lost, and a population prediction that went wrong. Many environmental scientists seem to remember him warmly for 'raising awareness'. They should not. His legacy is both stupid and vile beyond imagination. (1)

Attending the Unifying Ecology Across Scales GRC was one of the highlights of my PhD, and this year's edition is going to be excellent! All biologists interested in integrating diverse approaches to further our understanding of the natural world are welcome. Register early! shorturl.at/rIjWx

I am seeking a postdoc to join my group at UCLA -- ideally the candidate would have some experience in either population genetics or microbes/microbiome (computational background needed). We have a range of projects and are happy to tailer to your interests. Please dm/email me if interested.

If you are a student whose NSF GRFP application was returned without review for vague 'eligibility' reasons: 1) Let your department chair & Graduate School know. Encourage them to contact NSF & congress 2) Write to your congressional reps. 3) Write to grfp@nsf.gov to request re-consideration;

Incorporating realistic ecological interactions changes our understanding of which traits are optimal in different environments, including the temperature-size rule. Awesome paper by David Anderson, outstanding former postdoc with me and Mary O'Connor.

This work grew from conversations and collaborations that persisted over eight years, through a postdoc, COVID, and two faculty positions. Work with great people, and don’t give up on your passion projects!

At the community level, collections of many *unimodal* population-level TPCs yield maximum interspecific growth rates that increase *exponentially* with temperature (the Eppley curve). These, too, are altered predictably by resource limitation.

Lastly, we show that our predictions, and ideas from Metabolic theory, are consistent with patterns in large compilations of data on the growth of autotrophic AND heterotrophic microbes, including different underlying responses to temperature.

At the population level, when birth and death rates increase exponentially with temperature, net growth follows the expected *unimodal* shape (thermal performance curve, TPC), with properties that change predictably with resource limitation.

I am recruiting a PhD student to work on microbial communities in Arctic ecosystems. This is a great opportunity for someone interested in combining field, lab, and computational approaches. If you are interested, message me for more information.
