The symbolism of plants

With the forthcoming 12 monthly articles we want to give a certain insight into how former generations and cultures, having far less access to rational and experimental scientific knowledge than modern scientists, tried to explain and interpret their observations in the plant kingdom.

That’s from Riklef Kandeler and Wolfram Ullrich’s introduction to their series on “Symbolism of plants: examples of European-Mediterranean culture presented with biology and history of art” in the Journal of Experimental Botany. ((This seems to be something of a tradition. There was a similar monthly series on plant culture in 2002 by Nicholas H. Battey.)) It started last January, and each month brings a new plant. June’s installment has just come out. It’s on lilies. No crops, really, though some of the plants treated are used as food (e.g. Crocus). The focus is on plants which carry with them the heaviest symbolic baggage. You can set up an alert with the journal to tell you when the next in the series will come out.

Bedbugs redux

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.

VIR at war

I’m going to have to take back what I said about English Russia. Just a couple of days after it featured old photos of Russian agriculture, today there’s more of agrobiodiversity interest. Sergei Larenkov mashes up images of modern St Petersburg with photos taken during the siege. Below is one of St Isaac’s Square. There are several others. It was a cabbage patch during the war. The building in the middle is — and was — part of the Vavilov Institute.

Compare it with the picture I took recently.

Rokupr rotting away

An opinion piece in the Awareness Times of Sierra Leone decries the current parlous state of Rokupr Agricultural Research Station. It starts, however, by waxing lyrical abut the past.

Established about half a century and decade ago, the Rokupr Rice Research Station was a darling vision of the early colonialists who among other considerations were fascinated by the fertile ecologies and enviable terrain of the Scarcies coastline… With rice as a popular diet in West Africa and around the world, Sierra Leone in the shadows of Rokupr Rice Research was put on the spot light of fame and popularity. Rokupr became internationally known.

Indeed. And not only for rice breeding, but also for being at the forefront of the scientific thinking about on-farm conservation of plant genetic resources in the 1990’s, as part of the Community Biodiversity Development and Conservation Project. Alas,…

…[t]he present condition of Rokupr Rice Research is dismal. The one time elegant roads in the station premises are presently all gorges and death traps. The compound remains uncared for. Trees, shrubs and grass have overgrown and form a canopy over the compound. The trees are dens for giant snakes and other poisonous pests. Research trial fields are abandoned. There are no resident senior staffs and research activities have been suspended for ages. The compound looks marooned and deserted. The aura of research is dilapidated. Laboratories and staff quarters are ransacked and in dear need of renovation. Staff morale, dedication, and motivation are low and devoid of promise.

A pity, especially since an alumnus of the station was minister of agriculture until fairly recently. Who will save Rokupr?
