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.

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

A great conference to go to this summer – who could oppose unifying ecology on multiple scales? I just finished attending a great conference (Island Biogeography Society), which reminded me how fun and intellectually stimulating a really good conference is. So here’s my recommendation f…

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

Figure demonstrating how the ordering of temperatures through time determines whether an ectothermic population experiencing those temperatures will go extinct

Thrilled to share that my first dissertation chapter is now published at Ecology! dx.doi.org/10.1002/ecy....

We embed TPCs into population dynamics to show how changing temperatures' ordering — not just its distribution — increases extinction risk (i.e. heatwaves matter!)

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.

Nutrient availability modulates impacts of short‐term shifts in temperature and grazing on phytoplankton composition and size structure The significant contribution of phytoplankton to global primary production is regulated by several abiotic and biotic factors, which are often difficult to account for in natural systems. To address ...

Do nutrient pulses alter phytoplankton communities? Yes. What about short-term shifts in temperature? Well, it depends.

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;

NSF GRFP applicants (and mentors): Was your application Returned Without Review and deemed ineligible despite fitting in the allowed topics?
1) Write NSF
2) Write your Congressperson
3) CC us at grfp@grant-witness.us so we can compile + follow up

Incorporating realistic ecological interactions changes our understanding of which traits are optimal in different environments, including the temperature-size rule.

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 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.

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.

Ecologists recognize the importance of integrating across scales, yet our models often target specific scales. Our new paper presents models of population growth that scale up to explain community-level patterns, including interactions of temperature, light & nutrients. doi.org/10.1002/ecm....

Poster for 90 minute workshop on HOW TO DESIGN BETTER EXPERIMENTS, by Mridul Thomas & Ravi Ranjan. 

Details: September 23rd 16:00 CEST ; 14:00 UTC

Description: 

Experimental designs can make or break an experiment. A good experiment has a clear goal and efficiently uses experimental resources to achieve that goal. In this workshop, we will review what experiments are for, basic and advanced principles of designing experiments, and how to use simulations to evaluate designs before actually doing the
experiment. We’ll do a moderate amount of coding in R and so experience with this would be helpful but is not required. We intend to have small-group discussions to help participants develop their own experiments, and encourage participants to think of a specific question they would like to answer with an experiment.
