Hello! I am an anthropologist studying the archaeology of landscapes, especially in the Bolivian Amazon. I am interested in agriculture, especially the possibility that archaeological evidence could be useful for farmers today.

Isn't that crazy -- there was a dog breed which was solely dedicated for powering wheels which turned meat on fire!?
Just how many kinds of such 'techno-animals' existed and went extinct? This is cultural and biological evolution all at once.

Ok...sure. You NEED eels at your Christmas feast. But what *else* do you need?

In 1245, Henry III ordered his sheriff at Cambridge to deliver the following to him by Christmas:

2 cranes
24 swans
10 boars & their pickled heads
50 bitterns
6 peacocks

And 10,000 eels. Of course.

In ancient hilly landscapes, agricultural terraces were a necessity for farming. In #BronzeAge north-east England, their construction coincides with that of roundhouse settlements and field systems, possibly indicating a population boom.

Many plants defend themselves with physical defenses. Spikey armaments, at various scales, are the subject of this week’s posts. Let’s start with root spines: Adventitious roots that harden & become sharp. Cryosophilla palms do it best. 📷: Cryosophila warscewiczii #root #Arecaceae #Botany 🌾🧪🌱

Our Latin America bureau @mongabaylatam.bsky.social won the Global Shining Light award last night 🏆 💯

This #RemembranceDay we invite you to think on the enduring effects of conflict on modern landscapes. Near Vimy 🇫🇷 is a patch of fenced-off forest along the old Western Front. These exclusion zones materially and ecologically 'remember' armed conflict.

A new survey found that biking is down -- way down -- among kids 7-17 over the last 30 years.

"By adding more bike-friendly infrastructure—lower traffic speeds, separated bike lanes, calmer intersections—local governments could encourage children and other residents to start riding again. "

Yup.

Kids on bikes once filled the streets. Not anymore.

Worker-to-worker education has always been an essential ingredient of the Fair Food Program’s unique success.

These education sessions happen on-the-clock, each season, with staff members of the CIW engaging farmworkers on their rights and responsibilities under the FFP.

Fossil åker! Så snyggt!
Raking shadows thrown by low sun emphasise the terraced banks of an extensive IronAge/#RomanoBritish field system on the steep N-facing slopes of Burderop Down, Wilts. ... AND the ditches of a #medieval sheepfold that cut across them.

I once did a *very shitty paper on how the Big Ten actually acts as a unit generally led by MI, UIUC, and Wisconsin based on the networks of their investments and I'm unsurprised.

I am surprised it was Rutgers who started it here though.

*It wasn't a good paper but it was an OK analysis
This exciting resolution from Rutgers University Senate is exactly the kind of model I think higher ed needs: a mutual defense pact of, in this case, Big 10 schools. They call for member institutions to create a joint defense fund and make resources available to any member institution under attack.
