Mapping America

So there I was Scooping away, and what should turn up among the stuff I follow, and almost side by side on the screen to boot? Well, this map of obesity rates and farmer markets in the USA:

And, I kid you not, this map of food insecurity in, you guessed it, the USA.

Eyeballing does suggest a certain association between obesity and food insecurity, doesn’t it? Talk about the double burden of malnutrition. Oh the fun one could have mixing and matching such maps, and the no doubt dozens of others that also exist out there, documenting the geographic distribution of McDonald’s, organic farms, drunkenness, gyms, pet ownership, house prices, fizzy drink consumption, weed busts…

Crop wild relatives of the USA

I’ve just come across the Jepson Flora Project, which

brings together all of the floristic references and data of the Jepson Herbarium. Resources of the Flora Project are directly linked the the Consortium of California Herbaria, CalPhotos, the California Native Plant Society, California Exotic Pest Plant Council, USDA-Plants database, and many other external sites. The Friends of the Jepson Herbarium help the Jepson Flora project carry out its work.

It doesn’t look particularly nice, but I do like the idea of aggregating all kinds of information about each taxon, like Helianthus californicus for instance, via the Jepson Online Interchange. From that admittedly ugly page you can dig deeper, and for example get a digest of taxonomic, distribution and phenology information based on specimens from members of the Consortium of California Herbaria. They don’t make it particularly easy for you ((You have to walk the data through the Berkeley Mapper.)) but you can, wonder of wonders, even export the location data to Google Earth, where you can mess with it as you wish.

I wonder how many other US states have something similar. And whether all their data on crop wild relatives could then automagically be aggregated up to the national level. Colin, are you there?

Nibbles: Chillies, Catfish, Blight, Beef, Svalbard, Biofortification, Agriculture and health book, Ahipa, GBIF, Pacific grape and nuts, Cassava and marriage, Amazon, Lost genebanks, Vietnamese food, Yoghurt

Another use for chillies: keeping errant apes away.
Catfish are the new tilapia.
New fungicide-resistant strain of potato late blight found in UK. (How do they name these things?)
The chickenization of the US beef industry, on NPR. Salutary.
The Seed Warrior of Svalbard gets over-exposed.
What HarvestPlus is doing on each of its crops, in a handy brochure. And more on the same subject but a different crop from Bill Gates himself.
But that’s just one aspect of the relationship between agriculture and nutrition/health. Right? Right.
You also need dietary diversification, right? Right.
What’s that you say? Biodiversity databasing need not be hellish?
Danny waxes nostalgic about Wallis and Futuna grapes. He and I also met a few nuts in the Pacific in our time. Grape-nuts. Geddit?
Latest Plant Cuttings includes big piece on cassava.
And you can put that in an ecological context.
Do you have a forgotten germplasm collection?
Vietnam gets its first EU Geographic Indication. Can’t help thinking it need not have bothered.
Greek yoghurt, on the other hand…

Nibbles: AnGR genomic resources, Agroforestry fund, US climate map, Cassava rules

Big new project on farm animal genomics. Gene-jockeys lick lips.
Big new push to raise money for the Moringa Fund. Agroforesters lick lips.
Big new hardiness zone map unleashed by USDA on unsuspecting world. American GIS people and gardeners lick lips.
Bill Gates mentions cassava. CIAT licks lips.

Brainfood: Conservation policy, Grasspea breeding, Modeling rice diseases, Maize roots, Literature on new oil crops, Native vs non-native trees in Indonesian city parks, Cherimoya maps, Darwin Core, Seed dispersal and conservation, Oxalis variation, Polyploidy and variation, Pollinators, Microsymbionts, Plant migration, Culture and agriculture

As ever, we have added most of these references to our public group on Mendeley, for ease of finding. “Most?” we hear you say. “What gives?” Well, Mendeley and some academic publishers still don’t play nicely. There’s nothing to stop you adding the paper in question by hand, if you’re so inclined, but we don’t really have the time. And if you do, please do it right.

Why are some biodiversity policies implemented and others ignored? Lessons from the uptake of the Global Strategy for Plant Conservation by botanic gardens. Because there are no feedback mechanisms?
Genetic improvement of grass pea (Lathyrus sativus) in Ethiopia: an unfulfilled promise. Conventional breeding for low ODAP hasn’t worked, so forget about solving that problem through conventional breeding, and move on to other problems, or use genetic transformation.
Modeling and mapping potential epidemics of rice diseases globally. It is not particularly well done, but one is surprised to see it done at all. NiM ((Not in Mendeley.))
Morphological and physiological characteristics of corn (Zea mays L.) roots from cultivars with different yield potentials. More roots means more yield. Among some modern varieties anyway. Under some conditions. NiM
Trends in literature on new oilseed crops and related species: Seeking evidence of increasing or waning interest. And finding it, alas. Sort of. NiM
The green colonial heritage: Woody plants in parks of Bandung, Indonesia. Native species used to be used more, and should be used more again. NiM
Mapping Genetic Diversity of Cherimoya (Annona cherimola Mill.): Application of Spatial Analysis for Conservation and Use of Plant Genetic Resources. Cool maps of microsat hotspots.
Darwin Core: An Evolving Community-Developed Biodiversity Data Standard. The way out of Genebank Database Hell? Well, maybe the match that will light the torch that will show the way out.
Seed dispersal in changing landscapes. Fragmentation, harvesting, invasions and climate change affect seed dispersal in ways that need to be understood by conservationists. NiM. And the BBC’s more verbose take on it.
Distribution models and a dated phylogeny for Chilean Oxalis species reveal occupation of new habitats by different lineages, not rapid adaptive radiation. Title says it all, really. It’s not that a single lineage exploded as new habitats became available. Old lineages were pre-adapted to the new habitats. ((Finding the actual paper online could be really, really hard.))
Extensive chromosomal variation in a recently formed natural allopolyploid species, Tragopogon miscellus (Asteraceae). Polyploidy leads to all hell breaking lose in the genome for generations.
Overplaying the role of honey bees as pollinators: A comment on Aebi and Neumann (2011). It’s the wild bees, hoverflies and other native pollinators, stupid! But still.
Arbuscular Mycorrhizas Reduce Nitrogen Loss via Leaching. 40 times less, no less.
Distributional migrations, expansions, and contractions of tropical plant species as revealed in dated herbarium records. Eppur si muovono. And more on the paper. And more on herbarium digitization in general. what can I tell you, I’ve got apophenia.
Ecological and socio-cultural factors influencing in situ conservation of crop diversity by traditional Andean households in Peru. There are influences; and why wouldn’t there be?
