Do you want to know more about the ancestral composition of honey bees across different regions in Chile? Read the latest paper by @KDogantzis, @AmroYorkU, and their collaborators in Chile! link.springer.com/article/10…

Hot of the press. Playing back the tape of evolution showing how a single Asian honey bee colony invaded and adapted to Australia’s environment. With @KDogantzis and Ros Gloag from the famed Sydney social insect lab!

Sabbatical ends with Eastern Carpenter Bee @YorkUniversity after being in the great lab of @AmroYorkU with @KDogantzis and many others. It has been a pleasure! Going back @UniHohenheim @KomBioTa and looking forward to new research projects @mwk__bw

This amazing figure from yesterday's #IPCC report shows the potential of different approaches to mitigate climate change
It exposes two common misconceptions about 'natural climate solutions'

This image from today's IPCC synthesis report is brutal. The existing policy trajectory represents a profound failure of our governments, and of our international political system. We need much more aggressive mitigation and much stronger international cooperation.

Prairie strips are a farm conservation practice that requires minimal intervention and delivers huge benefits
By converting 10% of cropland to native prairie, farmers can reduce soil loss by 95%, total phosphorous loss by 90%, and total nitrogen loss by 85%

What do ya suggest we call this behavior?
📸: Erick.Higuera/IG
The female argonaut octopus shown here is demonstrating impressive social behavior that you’ve most likely never seen before…
👀 Picture this: a bunch of fearless octo-mothers, who have been working their whole lives to build the perfect egg casing by secreting calcite out of their arms, banding together to protect one another.
That’s what we think these female argonauts are doing.
Instead of braving the ocean solo, they lock arms and bring the most squishy & exposed parts of their bodies together.
🗣️ Argonaut to Argonaut: “Do you want to form an alliance with me?” “Absolutely I do.”
Each female puts herself at risk to safeguard the eggs of her fellow sisters. It’s difficult to watch— but believe it or not, there is NO research on this behavior.
Not only is this behavior admirable, but it also suggests that octopuses are capable of complex social behavior that is not yet fully understood.
The sense of unity and cooperation in female argonauts’ actions is truly inspiring.
These behaviors challenge the common belief that octopuses are solitary animals and show a level of intelligence that is still being researched.
If you read this far, comment “argo” and we’ll send you our top blog posts on this species so you can learn even more about em! (How she makes the shell, about the pea sized non-shelled male, and how they ride jellies around)
OK ok ok— if you’re still here— This video leaves us with a bunch of questions (maybe you can help?) …
1. Are the actions of argonaut mothers working together to safeguard their young an example of emotional intelligence? (the ability to understand and respond to the emotions of others) or is it something else entirely?
2. With a lifespan of ~1 year— is this simply an instinct or do they recognize each others vulnerabilities?

Is there a name for the feeling when you all you want out of life is to hunker down and eat pizza and watch movies but you also want to break new ground in your profession but you also want to quit society to live in the woods but you also want to go explore the world forever

#Antarctic sea-ice area is easily the *lowest* on record for today's date...

ALT Line graph time series of 2022's daily Antarctic sea-ice area compared to each year from 1979 to 2021. Lines are colored from purple in 1979 to white in 2021. 2022 is shown in red. There are no statistically significant long-term trends visible in this graph between November and January. Data are smoothed using a 5-day running mean from the Sea Ice Index v3.

Además de la calavera 💀 que luce en el tórax, la esfinge de la calavera (Acherontia atropos) presenta otra curiosidad: en lugar de néctar, el adulto de este lepidóptero 🦋 se alimenta de la miel 🍯 que succiona directamente de las celdillas de las colmenas. (1/3)
