How do scaling laws at the single-cell level give rise to macroecological patterns? We show that in plankton, power laws of nutrient uptake and grazing shape eco-evolutionary dynamics to produce scaling relationships at the ecosystem level. 🌊 https://t.co/MQsRszHXcX

Eco-evolutionary dynamics informed by allometric scaling can predict large-scale patterns across planktonic food webs.

I'm on team rebase. There are enough times when circumstances require a complicated merge (eg backporting a hotfix). Thus the goal for a regular merge should be a clean simple Git history

I'm super thrilled to share this new paper with David Vasseur out now in @Ecology_Letters!! 🙌 Interactions between temperature and nutrients determine the population dynamics of primary producers 🦠🌡️ https://t.co/0fbMjUZVsy

Here, we integrate the thermal responses of intracellular processes regulating phytoplankton growth to understand how temperature and nutrients collectively affect population-level responses. We...

Trophic position estimation has been a central issue in food web studies. Estimates using compound-specific isotopic analyses of amino acids were generally based on the trophic enrichment of glutam...

Huge undertaking by @FishSciSkeeles to raise fish for a year with or without supplemental oxygen to see whether it enhanced growth rates & supported the gill-oxygen limitation hypothesis. It didn’t! BUT, a cool finding RE oxygen extending the reproductive window!
For those still on here, I'm super stoked to see this one out there! 🐟🔥🤏 @Timothy_D_Clark @ScheuffeleHanna @DeakinSEBE @deakinresearch Supplemental oxygen does not improve growth but can enhance reproductive capacity of fish https://t.co/76bUBOa5mt A thread below 🧵1/n

We analysed 50 years of coral reef data to identify patterns in coral resilience, finding links between resistance, recovery and coral cover pre- and post-disturbance 🪸 Pls read and share to help justify the unfathomable amount of hours I put into this😅 https://t.co/OAFNsPfcC6

When using OLS regression, from where do we get the assumption the residuals are normally distributed? You don't need that assumption to minimize the sum of the squared residuals, nor to use the CLT to compute the SE's for the beta coefficients. So what's its origins?

Forgive me, for I am about to Bayes. Lesson: Don't trust intuition, for even simple prior+likelihood scenarios defy it. Four examples below, each producing radically different posteriors. Can you guess what each does? Revealed in next tweet >>

Basking sharks are what now?! New paper led by @haleydolton where we document regional endothermy in our favourite giant filter feeding sharky 🔥. Interesting implications for evolution and ecological advantages of regional endothermy; we thought it was only seen in apex 🦈&🐟1/3

Physiological Sighs (deep nasal inhale followed by 2nd brief nasal inhale, then a full exhale via the mouth) is not Yogic or “breathwork”. It is a naturally occurring breathing pattern that reverses hypoxia, occurs in sleep too & also happens to be the fastest way to de-stress.
