Happy to see out our latest work on studying animal body size variations using single cell transcriptomics to measure gene expression of individual cells. Learned my fair bit of statistics here, and most importantly I learned how to build wrapper functions for "complex" tasks in R (such as differntial gene expression) in a modular way. Thanks to all the authors involved! https://www.science.org/doi/10.1126/sciadv.adm7042 #singlecell #scrna #allometry #splitseq #planarians #generegulation

#30DayChartChallenge Día 17: Birds! 🐦 Hoy toca explorar relaciones en el mundo aviar con el increíble dataset AVONET. #RelationshipsWeek #Animals

Graficamos la Longitud del Ala vs. Masa Corporal (log-log) para >9500 especies. ¡Una relación clave en la biomecánica del vuelo! ✈️

Lo interesante:
1️⃣ Facetas por Hábitat: Vemos cómo la relación cambia (o no) entre Bosque, Marino, Pradera, etc. ¡La ecología importa!
2️⃣ Color por Orden: Los puntos coloreados muestran la diversidad taxonómica (12 órdenes principales). Passeriformes por todas partes!

Una visualización "complicada" (Día 15 😉) que revela la interacción entre tamaño, forma del ala, linaje evolutivo y ambiente.

Eagles, butterflies, and whales don’t appear to have much in common, but a new study shows that they — along with over 400 other flying and swimming animals of all sizes — flap with a frequency determined by a simple equation. Their beat frequency is proportional to the square root of their mass divided by their wing area. As you can see in the graph below, this scaling collapses pretty much all of the data onto a single line:

It’s surprising to find such a consistent relationship among animals of such vastly different sizes and types. The next big question for researchers will be unpicking exactly why and how animals evolved to use such a consistent pattern between their size and their wing(/fin) frequency. (Image credit: top – E.

Our study supports the central assumptions of #MST and highlights the role of allometric models to understand the #physiological responses involved in #plant #adaptation. #Allometry is more variable between genotypes than between environments. Suggesting that natural selection can lead to the genetic differentiation of plant allometries in different environments, but that environmental changes have limited effect on a genetically-determined type of allometry.

Using the #PHENOPSIS platform to automate measuring and testing #genotypes - Our study suggests that plant #allometry is genetically variable and might be related to different adaptive strategies to cope with stressing conditions.

Check out our new paper - Genetic variability and plasticity of plant allometry" led by François Vasseur - across 120 genotypes intraspecific #allometry adhered to predictions from #MetabolicScalingTheory https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2435.14281 1/n ...

I just asked #ChatGPT to give me some scaling and #allometry #haiku … Not bad

Scaling in biology,
Allometry and dimensional,
Space and time we scale.

From physiology,
To ecosystems and evolution,
Scaling laws we learn.

Scaling laws revealed,
From body size to species diversity,
Biology expands.
