Me too! I am also learning.
The new system is great, but there is much I need to learn as administrator. I am not an IT person, but I am happy for our network to evolve organically, and without haste.
Sorry, I am learning using this system!
Dear Dr Gallardo Lancho,
Thanks for revisiting our network, and your kind reply.
My main research interest for the last 30 years has been the history of taro, a root crop that also reached Spain several centuries ago, and which may have been associated with the introduction of rice into southern Spain and areas around Valencia. In Southeast Asia taro is often associated with rice in irrigated wetlands, and I have seen it growing alongside rice on the Nile river bank near Cairo. I have not found any modern references to taro as a cultivated crop in Spain. Perhaps rice has also declined, as it is such a water-intensive crop.
Best regards, Peter (Admin., Kyoto)
I saw usually taro in Latin-America. Rice is usually cultivated in Valencia (East), Badajoz (West), & Sevilla (South), Spain. You can find cultivated taro in Canary Islands (also Spain, in front of Africa), usually named 'malanga', sometimes 'ñame' (this name is used for two different species, but with edible roots), as in Cuba. I saw taro in some gardens of Southern Spain, but I believe that is not cultivated; I think that only is cultivated in Canary Islands.
Thanks - a very nice report for a very large area! Taro also appears as an ornamental in Italian water gardens. It may be an ancient usage across the Mediterranean. In Egypt, it is better known today as a vegetable, sold in every vegetable market (I spent a month in Cairo exploring markets - a great experience). I have seen photos of taro in the terraced fields of the Canary Islands. I also wonder if it has been incoporated into any Spanish-style dishes, even if it is mainly eaten by immigrant communities in Spain (as in other regions of Europe). I have seen photos of taro sold in the markets in Barcelona under a variety of non-Spanish names.
Dear Dr Gallardo Lancho,
A few years ago I helped write a discussion chapter in a book introducing research on ancient starch preserved in archaeological sites:
Barton, H. and P. J. Matthews (2006) Taphonomy. In R. Torrence and
H. Barton (eds) Ancient Starch Research. Left Coast Press: Walnut Creek, CA., pp. 75-94.
I wonder if you have noticed starch grains in soil particle size fractions of around 5-50 microns (the typical size range of starch, though it can be smaller or larger)?
What we need are proper soil science approaches to extracting starch from soild using techniques that have been calibrated (using known quantities of starch added to otherwise starch-free standard substrates) and optimised. This might allow some kind of endpoint analysis of the overall flow of starch (and photosynthesis-derived energy) into soils. It could be a useful way to analyse ecosystems as well as well as archaeological sites.
Or doping soils with starch, and then following the loss/recovery of starch over time could be a useful way to measure biological activity in a soil over time.
Best regards, Peter
Sorry, I just saw this message. I have not worked on starch. Perhaps Dr. Gonzalo ALMENDROS had; please contact with him: <humus@mncn.csic.es>.
Sorry for the delay. Best regards & nice 2017.
