The Sourdough Habitat and its Monuments - 2017
The Habitat
A habitat is an ecological or environmental area that is inhabited by a particular species of animal, plant, or other type of organism. The term typically refers to the zone in which the organism lives and where it can find food, shelter, protection and mates for reproduction. It is the natural environment in which an organism lives, or the physical environment that surrounds a species population.

Sourdough bread starter. Sourdough is teeming with bugs—some 50 million yeasts and 5 billion lactobacilli bacteria in every teaspoon of starter dough. (http://discovermagazine.com/2003/sep/featscienceof)
"If the loaf is the body, the starter is the soul".

Poetics of Anthropocene - Sourdough bread
"There are millions of kinds of bacteria and fungi on Earth. We have found several thousand species in human belly buttons alone. Yet if you mix flour and water, the community of organisms that colonize the resulting concoction is almost always composed of a small handful of organisms that are able to leaven bread, yielding a sourdough starter. How this happens is one of civilizations great mysteries, a mystery at the heart of the bread making..." Rob Dunn Lab (http://robdunnlab.com/projects/sourdough/)

DAN-lab succeeded in identifying the microbes in my sourdough.
It looks like mine sourdough is very poor in species.
Metaphorically, I could say it is very homogen and "clean" colony.
When I study other samples on the map, I can see some have very rich diversity in population.
