We use a coordination game to study repeated emergence and abandonment of mutualistic interactions. The game reflects that mutualisms must be widespread to generate robust benefits. Mutualisms can collapse even in the absence of cheating and even if they would result in higher fitness. rdcu.be/eWnIc

No, they are only alienating a minority of entitled degenerates who think that chasing animals to exhaustion and throwing them live to be ripped apart by a pack of dogs is a bit of a laugh. This should have been confined to history just like bear baiting, dog fighting, and hare coursing long ago.

Our government’s priorities are entirely backward. And purposefully so.

So reindeer (Rangifer tarandus) can't fly, but they are VERY MAGICAL. For example, their EYES CHANGE COLOR during the year & they're one of the few large mammals that can see UV. Golden brown in summer, deep blue in winter. Let's talk about the unique visual adaptations of Rudolph and company.

To remember William Bond, you could listen to his powerful talk on behalf of grasses! It is a seminal lesson in savanna ecology. Personally, I also find it nice to hear his voice. jgpausas.blogs.uv.es/2021/02/21/a... 🧪🌎🔥🌿🌳🪴🌐 #PlantScience #savanna

A great loss. A formidable and eloquent mind.

In the year of our Lord two-thousand-twenty-five, there are still shockingly diagnosable, legit never-before-seen-by-scientists new bird species out there to be discovered

The stock market's gains are being overwhelmingly driven by seven Big Tech companies who have invested heavily in AI, which has made tech oligarchs even wealthier. But when that AI bubble bursts, the rest of us will be stuck holding the bag. Be warned.

I suspect the spirits of a John and Danny Thompson are slumped there some nights, sleeping off another night of celestial improvisation...and quite a few beers.

What a terrifying war zone!!!!??!!

I’m pretty sure I found the exit once, but I may still be lost somewhere in there.

everybody gets to choose one climate solution they're allowed to hate as long as they 100% support policy and infrastructure to implement it. I loathe biking (because I take it personally when people try to kill me) but bring on the protected lanes and secure bike parking

We need more provocative papers like this …

As always, Larry and Paul get it spot on!

Zero scandals, strong leadership. Repost if you like President Obama too 🙌🏻

Civilians cannot be targets. Never. The images from Gaza are unbearable. The EU reiterates its call for the free, safe and swift flow of humanitarian aid. And for the full respect of international and humanitarian law.
