Excited to share our latest paper on lizard contests and agonistic signals! Read on for a daydream on how being a lizard could be like, disguised as a discussion on the relative impact of static colour patches and behavioral displays in animal contests 🧵 https://t.co/dDIrcNIFgT
🚨 Fifty years of research on "badges of status" in animals, and we still don't know if the hypothesis holds. In our new reply, we argue that the evidence is shakier than recently claimed.

We often assume that reflectance is “spectrally well‑behaved.”
If an animal is bright or dark in the visible, surely the rest of the spectrum just… follows along?

For obvious reasons, mating in hedgehogs is a delicate operation.
The female has to adopt a special body position with her spines flattened. On the bright side, newborn hoglets have no spikes.
En su momento dijimos que la ley de bienestar animal estaba tan mal planteada que iba a traer paradojas y problemas. Pues ya van llegando... Sobre linces y gatos callejeros https://t.co/9MYOP2ML6S
@festivalcelsius Que buena tanda de anuncios! Os envié un mail hace unas semanas con una propuesta sobre divulgación científica y fantasía...tenéis pensado hacer algo así ?
Cristo ha vencido a la Muerte.
Cada año procesionan en la Semana Santa española las "Caninas", los esqueletos que forman parte de las alegorías del Triunfo de la Cruz sobre la Muerte. La más célebre es la de Sevilla. Pero hay más... ↘️
In an attempt to explain just why it is that some 77 million Americans voted for the dumbest man alive to be their president for a second time, I’m absolutely delighted to present you with the expanded list of US food that you cannot legally sell in Europe!🧵
Why does this inspire such disgust and conflict in us?
It's hard to argue that this solution isn't better. Better a brainless sack of protein than a living creature capable of pain, longing to see the sky but forced to live in hideous lifelong bondage.
So why does the Harvest Hen or the Domesticated Meat Pig feel worse?
I think it's because it makes the instrumentalization visible. We already treat living creatures as production units, but this takes it "too far"... it stops pretending otherwise. An organism that has been openly, unapologetically designed as a object.
And for some people, in some ways, something about that honesty is harder to look at than the cruelty we've already normalized.
Original brainless meat pig "bodyoid" art by @Coolio_Art made me want to make my own.
Watching wildlife documentaries you would think the world was teeming with wild life
But in reality there is hardly any wildlife left and what remains is rapidly being destroyed
What took billions of years of Earth fine tuning is being destroyed in a few decades
La vida dels rapinyaires no és senzilla. Tirar endavant suposa un fràgil equilibri entre costos i beneficis, que es trenca quan uns quants perdigons entren en joc 🦅

Lizards and the colors we can’t see! 🦎✨ Juvenile Podarcis muralis undergo ontogenetic color changes that are invisible to humans but perceptible to conspecifics, likely functioning as social signals. #Herpetology

The African wild ass (𝘌𝘲𝘶𝘶𝘴 𝘢𝘧𝘳𝘪𝘤𝘢𝘯𝘶𝘴) is the most endangered wild equid in the world. 🐎
Found mostly in Eritrea and Ethiopia, the species’ numbers (approximately 200 mature individuals) are declining due to climate change and human and livestock impacts.
In Eritrea, however, the population is stable and slowly increasing due to strong commitment from the government and local communities. 🌍
At our upcoming #CMSCOP15, more #MigratorySpecies will be considered for international conservation measures under our Convention. Learn more: https://t.co/vX9Qa1hoQ4

Me llamo Jesús Martínez del Vas y soy ilustrador tradicional. ¿Me ayudas a difundir mi trabajo con un retuit? Cada vez que compartas, curas a un gatito, haces feliz a un unicornio, y ademas apoyas arte humano frente a la IA. ¡Mil gracias!
Si tota la vida a la Terra pesés 100 kg:
80 kg serien de plantes
14 kg de bacteris
2 kg de fongs
4 kg d’animals, que es distribuirien així…
2,4 kg d’humans
1,2 kg de bestiar
0,2 kg d’insectes
0,13 kg de peixos
0,06 kg d’animals salvatges
Bon dia!
En el marc del projecte d’elaboració del catàleg d’aràcnids del @PNMontserrat, en @MDomenech6 ha dissenyat un pòster amb algunes de les principals espècies presents al #ParcNatural. 🕷️🦂
Les reconeixeu? N’heu vist cap durant les vostres sortides?
Two new Science studies on lizard coloration reveal how a delicate interplay of genetics, environment, and social dynamics can either preserve or erase polymorphic diversity in species.
