Thank you, Ames!

Just back from Heartland and, before the jetlag overpowers me, I really want to thank everyone at the North Central Regional Plant Introduction Station (NC7) in Ames, Iowa for their incredible hospitality over the past week. I know this will get to them because a couple of the people working at the station told me they visit us occasionally. Grateful for that too!

The ARS facility at Ames is the oldest of the US plant introduction stations. It’s main crop is maize, of which it has a collection of about 20,000 accessions from all over the world.

But there are also some 30,000 accessions of a bunch of other crops and wild species.

Many of the crops require careful management of pollinators during regeneration and multiplication. Fortunately, there hasn’t been any colony collapse disorder among the beehives used and maintained on the station.

Like many of the active genebanks of the USDA National Plant Germplasm System, the one at Ames benefits from an almost symbiotic relationship with nearby Iowa State University, with some staff also having university duties and many students gaining hands-on experience in the genebank.

Also nearby is a fascinating prairie remnant, Doolittle Prairie, which houses about a dozen crop wild relatives. I’ll say a bit more about that in due course, but here’s what the place looks like at sunset.

Thanks again to everyone at NC7!

Mo’ better modeling

Two papers in the Journal of Biogeography suggest ways of improving ecological niche modeling, by including soil data and by recognizing that the range of a species may not be in “equilibrium with its climatic niche.” May need to blog in more details about these…

Incidentally, modeling species responses to climate change is no longer just an academic exercise, it’s a policy tool:

Brazil has shown the way with extensive modelling, leading to zoning schemes where farmers can obtain cheap credit for planting crops recommended by the models. It is now among the top three exporters for ten global commodities, including coffee.

Towards an ecologically-informed agriculture

What we’ve tried to do on a couple of occasions is look at conferences or publications of perhaps only slight overall agrobiodiversity interest and highlight the little bits that do fit here. So it’s nice when someone does it for us. The Ecological Society of America‘s 94th Annual Meeting is currently on in Albuquerque, New Mexico and, among all the other stuff, there’s a session presenting “ideas on how our agricultural practices can take lessons from natural environments.” Fortunately, EurekAlert is there, with summaries of presentations on turning annual crops into perennials, landscape diversity and pest enemies, and reduced tilling and soil microbe diversity. ESA has a blog, EcoTone, as well as a stable of journals. Nature’s blogger is also at the conference.
