Ever wonder what a bird sees? If so, read on!

Purple has always been my favorite color. But purple's not just pretty--it's a special type of color. If you look at a rainbow, you won't see purple. That's because purple is what we color scientists call a 'nonspectral' color. 1/n
Instead of being formed by a single light or mixture of similar lights, purple is formed by simultaneously stimulating our non-adjacent red-sensitive and blue-sensitive cones in our eyes. 2/n
Since purple is my favorite color, & birds are my favorite animals, I wondered, "Can birds see purple?" Today, our paper led by Dr. Cassie Stoddard with @dylanhmorris @B_G_Hogan @DavidInouye1 Ed Soucy is in @PNASNews that shows that yes, birds can! pnas.org/content/early/… 3/n

„GDP growth in crisis“ „We need to save the economy and restart growth.“

This crisis shows, how much we take growth for granted: its natural, necessary & good. However, this view is rather new. How did it emerge?

5 years ago, I published a book on this @CambridgeUP. Thread 1/
Yes, modern economies are structurally dependent on economic growth and accumulation. But growth is also an ideology: it unleashes promises, frames thinking, disciplines societies. This ideology only emerged in the 1940s, as did the term in public and academic discourse 👇 2/
What can we learn from this history? A lot🙃
First: „The economy“ is an invention that masks markets and profits as inevitable and natural. GDP statistics were highly controversial among those economists who first invented them. And this has large repercussions, to this day. 3/

[THREAD] on #Western #XRW #foreignfighters in #Ukraine war as @FightExtremism publishes my report on the issue 2day. Main Q: what it takes to become such a fighter? Who are they? Here I will summarise the main findings for your convenience. Link: counterextremism.com/sites/default/… 1/ Image
2/ I began researching this back in 2014 – when I saw this clip with #France #foreignfighters on #DNR #LNR side of the war in #Ukraine. I was surprised, to say the least.
youtube.com/watch?v=ahdROt… Image
3/ As it turns out, a few hundred #Western ers with #XRW convictions travelled to fight in #Ukraine on EITHER side. Many had known each other from before the #war in #Ukraine.  Below is a map of the main mobilisations for the war. Note the scale of the #Russia n for BOTH SIDES. Image

Since I've not been paid or replied to, I am declassifying. One of the biggest hurdles in building high speed rail is paying for the project. The solution is built in from the beginning. Its not just that you build it, its how you build it.

Right after hurricane Harvey Texas was flooded and I was talking about how the maglev would still be running because it was elevated. All you need to do is make it to the terminal. Thats when Trump declared National emergency and classified my work under nuclear preparedness.
Imagine a bridge, that instead of crossing the highway, runs lengthwise. It's elevated so it doesn't get in the way of animals or humans. It never stops, it never slows. Because it is elevated, accidents are almost unheard of. Making emergency evacuation safe and quick.

[FR, ENG below] Hello Twitter !
Je suis Louis, bientôt diplômé en #écologie et #épidémiologie des maladies transmissibles, et à ce titre, je recherche une #thèse pour la rentrée 2020 !
Mon CV est juste là 👇
Les RT sont évidemment très appréciés !
Je souhaiterais étudier les 1/9
maladies infectieuses humaines liées à l'urbanisation et aux contextes urbains, soit dues aux concentrations de populations, soit aux avancées technologiques (maladies dues aux contaminations de réseaux d'eau et leur épidémio, par exemple). Les maladies sexuellement 2/9
transmissibles m'intéressent beaucoup, et je suis également très attiré par les aspects de spatialisation/SIG, et la sociologie des maladies transmissibles (comportement, perception des risques, ...). Mes agents pathogènes de prédilection sont les parasites, les bactéries et 3/9

#AquaFonsVitae, first take:

Remarkably situates itself in the radical present, aka #COVID19, para 6. Reminder: this is a text on #water.
Explainer for newbies: Vatican emphasis on “connectedness” and “integral human development” are key Catholic Social Teaching (CST) terms, used in reference to #water since approx 2002 (see my book) and #ecology (see #LaudatoSi, 2015).
… as is this doc’s subsequent emphasis on universal destination of created goods (see #JustWater ch. 4), right to safe environment, and access to potable water. All of this is intro paras and is classic CST on water, though here more condensed than ever before! Fun.

Must read today: #Ecology of #Disease.

Sixty percent of emerging infectious diseases are zoonotic, originated in animals & more than 2/3 of those originate in wildlife.

In last 4 decades all major viruses are result of Human encroachment in wild areas.

nytimes.com/2012/07/15/sun…
The Nipah virus in South Asia & Hendra virus in Australia originated from fruit bats.

AIDS, for example, crossed into humans from chimpanzees in the 1920s when bush-meat hunters in Africa killed and butchered them.

Disease, it turns out, is largely an #environmental issue.
"Diseases have always come out of the woods and wildlife & found their way into human populations — the plague and malaria are another examples."

When we break the ecosystem, say an intact tropical forests, by removing something we remove the protective link also.

So happy to see our paper “Coexistence of #Nestedness and #Modularity in Host-Pathogen Infection #Networks” published in @natecoevo. We uncovered hidden dimensions of infection networks, which challenges established views in #ecology.
nature.com/articles/s4155…
Our goal was to understand how the environment mediates in the pattern of host-pathogen interactions, i.e., nestedness and modularity. To do so, we gathered empirical data on plant-virus infection networks surveyed at different habitats in central Spain, from 2000 to 2002.
But standard analyses of bipartite networks reported ambiguous results, and could not explain structural dependence on seasonality and habitat differences. Looking at networks is helpful, but nearly not enough to fully grasp the complexity of natural infections.

Hey #weather research scientists! We are looking for your expertise! Are you interested in wind/temp profile at night? Are you using or wishing to use doppler on wheel? We could have something to propose to you! #severeweather #aeroecology #DOW 1/n
I'm a research scientist in #forest #ecology at the @cflscf (@NRCan). With a high-expertise team, we are looking at the dispersal patterns of the most important pests in eastern North American conifer forests: the #sprucebudworm. 2/
@cflscf @NRCan #Sprucebudworm #outbreaks occur every ca 30-40 years and can last 5 to 15 years. The last major outbreak (1969-92) covered 55 M ha (yes MILLIONS !) and resulted in tremendous losses in the forest sector. (below: area defoliated in 1975). 3/

Today's Applied Complexity Symposium begins with a panel on Computation and Complex Economies, feat. Rob Axtell, Joshua Epstein, @C4COMPUTATION, Blake LeBaron, John Miller, & @MelMitchell1

(Follow this thread for live coverage all day...)

#complexsystems #economics
4 Principles of Collective #Computation:

1 Ground truth (objective reality)
2 Effective ground truth (what we agree on, whether or not it is accurate)
3 #Information can be collectively encoded in #networks
4 Outputs are a product of collective dynamics

@C4COMPUTATION right now
"I think #economics really needs to adopt a generative framework with agent-based models of cognitively plausible software people...[and] we don't choose to fear."

Y'all, I just need to brag about the students in my Barrier Islands class. While studying for their exam (which they're taking right now), they created a bunch of barrier-island-themed memes that combine #geology concepts, #coastal issues, & #humor. 1/
Almost all semester I've explained how most barrier islands worldwide are geologically "new," having only been made <10,000 years ago, but that the Georgia barrier islands are composite, made by two different shorelines during the Pleistocene & Holocene. #geology 2/
We also recently learned about how humans have interacted with barrier islands during those past <10,000 years, and how it changed from seasonal use to unsustainable over-development. #geology #coastal 3/

Canned #seafood #mercury concentration results from class experiment are in & were as expected. Hg in ppm, wet weight w (SD), n=3 cans for each:
Clams: 0.01 (0.001)
Salmon: 0.013 (0.001)
Chunk light tuna: 0.059 (0.017)
Albacore tuna: 0.28 (0.041)

So what does this mean?
We found what was expected based on recommended lists
Albacore levels similar to published studies, all of which typically show this fish w higher and much more variable Hg than FDA risk assessment and publication. ncbi.nlm.nih.gov/m/pubmed/15364…

Our preprint of Mammalia-wide evolution -- announcing a new tree of life for 5911 species based on a single DNA matrix and fossil node- and tip-dating. We show how ecology (vagility, latitude, diurnality) best explains living diversity & speciation rates. doi.org/10.1101/504803
2/ Bayesian posterior sets of 10,000 trees are built using a 'backbone-and-patch' framework and 31-gene supermatrix of 4098 species (70% of total). This approach gives realistic uncertainty in branch lengths and topology for comparative analyses of mammalian evolutionary rates.
3/ We show that rates of species diversification vary through time: 1) tree wide, with an uptick in lineage turnover near the K-Pg boundary matching that seen in mammal fossils; 2) among lineages, with 24 major rate shifts detected across the tree; and 3) within clades (rodents!)

I sometimes feel @georgialibs don't get enough high quality, academic press #history & #sociology books. Using the GA Pines automated system, people who are members of participating libraries can get a number of very good books which have recently come to my attention.
"The oldest living things in the world" by Rachel Sussman gapines.org/eg/opac/record…. This photo essay book is a beautiful, mind-expanding paean to our biosphere. (I realize this is a #science #ecology book)

The water in the pipeline cannot fix the leaks. Contrary to the advice #WomenInSTEM & #POCinSTEM receive, we cannot actually #leanin to solving the problem of #genderbias & #racialbias in #STEM & #academia. Thanks to @NatureEcoEvo & @RoinnAnLuisigh for this chance to say this. 1/
A few months ago, @Nature published a piece with advice on how senior women can confront #genderbias. While the advice contained therein was useful, the title was enraging. nature.com/articles/d4158…. 2/
It led me to rage tweet a thread of statistics on #genderbias in #STEM, and that thread blew up And then I got incredibly lucky when @RoinnAnLuisigh offered me the opportunity to turn it into a column. Working with her was AMAZING! 1000% fantastic 3/

npr.org/sections/goats… @NPRGoatsandSoda Usually a big fan of your journalism, but you guys did a disservice to your readers in the piece on gene drive in A. gambiae. Why would you reach out to anti-GMO activist Dr. Ricarda Steinbrecher for comment on this research? #malaria
First of all, asking Dr. Steinbrecher to comment on the consequences of using genetic engineering to suppress a disease vector is a bit like asking the pope about a newly developed form of birth control.

Of COURSE she’ll be against it - for ideological, arbitrary reasons
Plus, Dr. Steinbrecher’s degree is in developmental biology, not #ecology. Her statement about “ecosystem crashes” is absurd, and displays her ignorance in this area
