Prince buys apples

Regular readers will remember last year’s flap over the UK’s National Fruit Collection, which is looked after by the Brogdale Horticultural Trust and managed by the University of Reading at Brogdale, Kent. I won’t rehearse the details again, but suffice to say there was some doubt about the collection’s future. There’s now news from the Daily Telegraph that the collection has been “saved” by the Prince of Wales:

…three separate collections of the 1,000 most important breeds have been sold to the Prince of Wales, the Co-operative supermarket group and an anonymous Scottish businessman. ((Actually, not so anonymous.)) Each will plant their saplings in different parts of the country.

There’s not much more detail than that in the article, and of course we’ll work our contacts to try to find out more, and indeed to verify the accuracy of the newspaper accounts. But there are a couple of points about this statement that are a little worrying. At the very least, the whole thing raises a lot of interesting questions.

Let me start by saying that it’s certainly a good idea to safety duplicate (or triplicate in this case) germplasm collections in different places, especially field collections, which are particularly prone to accident and mishap. ((I’m afraid I dont know if the collection is maintained in tissue culture under slow growth or cryo conditions, but one would hope so.)) But how exactly were the thousand accessions chosen? There are 2,300 apple varieties in the collection. How does one measure the “importance” of each of these? One measure might be how much they’ve been used, either directly in plantations or in breeding. But wouldn’t such varieties be the ones in least need of conservation? It would be good to know what criteria were used to make the selection.

My second worry is over the fact that the germplasm has been “sold.” For how much, exactly? And how was the amount calculated? And what does that mean about access to that material by potential users, either in the UK or overseas? ((Added later: I should have pointed out that it is not clear from the newspaper account whether a copy of the collection will remain at Brogdale.)) Apple is on Annex 1 of the International Treaty on Plant Genetic Resources for Food and Agriculture. Ex situ conserved Annex 1 material in the public domain and under the control of a Party to the Treaty, which the UK government is, is supposed to be made available to users under a “facilitated” access and benefit sharing regime. Does this privatization of part of the collection affect its status under the Treaty? If so, has the Treaty Secretariat been informed? It’s not as if the new owners won’t be trying making money out of it:

The Co-op intends to produce a “heritage apple juice” from some of the breeds by the end of this year. William Barnett, who heads up The Co-operative Farms’ 800-acre fruit-growing operation at Tillington in Herefordshire, where the apple trees are being planted, said: “Some of the apples date back to pre-Victorian times. They were originally dessert apples, but became less fashionable and failed as modern commercial varieties.”

What if someone else wants to try the same thing? Under what conditions will they have access to the material?

As I say, lots of questions. If anyone out there has the answers, we’d love to hear from you.

They shoot horses, don’t they?

Ok, that’s just a provocative way of introducing an interesting review in Trends in Ecology and Evolution describing how harvesting from animal populations can affect their genetic make-up. ((Fred W. Allendorf, Phillip R. England, Gordon Luikart, Peter A. Ritchie, Nils Ryman (2008) Genetic effects of harvest on wild animal populations. Trends in Ecology & Evolution. Volume 23(6):327-337.)) The following three types of genetic change are highlighted:

  1. strengthening or collapse of population structure
  2. genetic erosion
  3. selection

The take-home message is that management plans should recognize that harvesting changes not just the demography but also the genetics of populations. Very important for sustainable management of fisheries etc., but I bring it up here because it got me thinking: are any wild relatives of livestock exploited through harvesting? Things like these cute pigs, for example. And would the conclusions be very different for plants?

Pollinator diversity, pollination services and landscape change

That’s the title (or part of it) of a guest editorial ((Ingolf Steffan-Dewenter, Catrin Westphal (2008) The interplay of pollinator diversity, pollination services and landscape change. Journal of Applied Ecology 45(3), 737–741 doi:10.1111/j.1365-2664.2008.01483.x)) in the latest issue of the Journal of Applied Ecology which introduces a Special Profile entitled “Pollination and Pollinators” (mainly bees, actually).

The papers in this Special Profile cover several of these topics: two papers address the impact of habitat fragmentation and semi-natural landscape elements for population densities, species richness and community composition of bees (Brosi et al. 2008; Osborne et al. 2008). The next three papers focus on the combined effects of local and landscape-scale land use intensity and semi-natural or natural landscape elements on pollinators (Kohler et al. 2008; Rundlöf, Bengtsson & Smith 2008; Winfree et al. 2008). The last two papers focus on pollination functions and consider cross-pollination rates in a major crop (Devaux et al. 2008) and plant–pollinator networks in heathlands (Forup et al. 2008).

The papers are behind paywalls, but the abstracts are still quite useful.

I guess the overall message is that “land use intensification and habitat fragmentation do not only affect pollinator diversity and abundance, but also pollination services” because “pollination success of insect-pollinated plant species is usually not dependent on single, highly specialized pollinator species, but rather on a diverse community of pollinators.” In some places, of course, bees have lots more to contend with.
