A biomechanical model of predator-prey pursuit indicates that prey do not frequently escape because they are more maneuverable, but because predators' reaction times give the prey an advantage.

Cell Adhesion Pattern Shows Conserved #Scalings under #Geometrical Control

Studying the relationship between the size and the #anatomy and #physiology of #living #organisms has proven useful in deciphering what the key physical constraints are that apply to them. For instance, total adhesive pad area is found to #scale like organism mass over a wide variety of animal species, possibly to resist against body weight.

In this study, we apply this approach at the cell scale to ask how large-scale geometrical constraints affect the organisation of #adhesion patches and the size of #cellSubstrate contact at different stages of the #cellSpreading process. Indeed, #cells, like many animals, adhere to their substrate. For that, they use specific protein complexes, called #focalAdhesions, which form patches often situated at the cell periphery.

#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.

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.
