Caveman Forecaster is a blog about “the art and science of time series analysis and forecasting.” There was a post about a month ago about bedbugs that really piqued my interest. It seems that bedbugs (Cimex lectularius) were virtually eradicated in the US fifty years ago, but are making a comeback. That has even led to the organization of a National Bedbug Summit, which took place last month. The post was mostly about using Google search data to monitor and predict the seasonal outbreaks and longer-term trends. But it got me looking into the reasons for the resurgence, and wikipedia has a reasonable summary of that, with plenty of references. Basically, genetic diversity studies suggest that there was never complete eradication, but that the pesticide-resistant populations moved to alternate hosts, “have slowly been propagating in poultry facilities, and have made their way back to human hosts via the poultry workers.” So here’s another example of a human pest which can also hang out with agrobiodiversity, and jump back and forth.
Fungus flavours fermented food
Did you know that…
[t]he edible fungus Monascus purpureus imparts a distinct flavor and red color when added to fermented rice dishes such as those served in Asia.
Neither did I. But the boffins at USDA do.
Diversity on air
I’ve been listening to a radio programme about diversity in action. Called The Evolution Boomerang, from Soundprint, it examines three cases where diversity is important to agriculture and the environment. There’s a segment on GMO cotton and insect resistance, a segment on the need for genetic diversity at salmon hatcheries, and a segment on selecting bacteria to degrade a chemical that had never existed on Earth before humans manufactured it.
All good stuff, if you have half an hour to spare. You will need Real Player to listen.
Nibbles: Assisted migration, Livestock and ecosystems, Agrobiodiversity tourism, Earthworms, Fish, Cucurbits
- Assisted location is now managed relocation. So that’s alright then.
- Transhumance is good for ecosystem. Oh, and bison too.
- Geotourism in Yellowstone has a website. Can agroecotourism be far behind? I’m afraid so.
- No relationship between parasite load and genetic diversity in earthworms. Alas.
- “The naming of fish is a nightmare. They have more aliases than Maltese pimps.” Which is why Latin binomials were invented, duh.
- Pix of Colombian cucurbit (and other) diversity.
The connection between wine and beer is agrobiodiversity
Sandor Katz has even had a poem written about his singular obsession:
Come on friends and lend me an ear,
I’ll explain the connection between wine and beer,
And sourdough and yogurt and miso and kraut,
What they have in common is what it’s all about.
Oh the microorganisms, Oh the microorganisms. . .
But don’t let that put you off. Katz is the author of Wild Fermentation: The Flavor, Nutrition, and Craft of Live-Culture Foods. You can read the introduction, and various other excerpts online, as well as order the book, of course. Microbes are agricultural biodiversity too!
