Systematics ~ Sociome, Diseasome, Interactome

Tim Clancy spots this complex systems hierarchy infographic from Handbook of Systems and Complexity in Health, 2013...
"A great example of systems thinking. The Manifest (top), Latent (middle), and Deep Latent (bottom) levels of hierarchy in a complex system.  In truth there are many levels of hierarchy in any system -- and what gets modeled or represented is a design choice based on problem definition and boundary selection."

Ecosystem Engineers ~ Wolves Change Rivers?

MissC at Neatorama spots How Wolves Change Rivers by the folks at Sustainable Man...
"When wolves were reintroduced to Yellowstone National Park in the United States after being absent nearly 70 years, the most remarkable "trophic cascade" occurred. What is a trophic cascade and how exactly do wolves change rivers? George Monbiot explains in this movie remix."
Update: Whoops, stop the presses, in NYTimes OpEd piece Is the Wolf a Real American Hero?, Yale Forestry & Enviro Studies Post-Doc Arthur Middleton calls "BS" on this simplistic myth...
"This story -- that wolves fixed a broken Yellowstone by killing and frightening elk -- is one of ecology’s most famous. It’s the classic example of what’s called a “trophic cascade,” and has appeared in textbooks, on National Geographic centerfolds and in this newspaper. Americans may know this story better than any other from ecology, and its grip on our imagination is one of the field’s proudest contributions to wildlife conservation. But there is a problem with the story: It’s not true. [...] When we tell the wolf story, we get the Yellowstone story wrong."
As DailyKos quotes, this is damning...
"Perhaps the greatest risk of this story is a loss of credibility for the scientists and environmental groups who tell it."

Atlas of Economic Complexity ~ Pathways Book

MIT and Harvard colleagues just published The Atlas of Economic Complexity: Mapping Paths to Prosperity...
"The book goes deep into the question of cross country differences in income and shows that complexity accounts for roughly 1000% more growth than education, governance and competitiveness measures."
