This story is not particularly agricultural, but I couldn’t resist it. Brazilian researchers extracted the essential oils from a Piper sp commonly eaten by bats and then smeared the stuff on plastic fruits, which they then distributed in areas of damaged rainforest. The bats were attracted to the fake fruits, though they wouldn’t normally fly in degraded forest. Why go to all this trouble? Because the bats spread lots of seeds via their faeces, and could thus be used to restore the vegetation.
Researchers have estimated rates of reproduction and survival for the marbled murrelet by “comparing the ratios of birds in different age groups using 170 specimens collected between 1892 and 1922 housed in the collections of the California Academy of Sciences and the UC Berkeley Museum of Vertebrate Zoology … with values predicted from comparison with other bird species, and with contemporary rates obtained from murrelets they captured at sea and from their mark-recapture studies.” The results suggested that birth rates were almost 10 times higher for this endangered seabird 100 years ago than they are today. Read all about it here. That’s a very creative use of a biodiversity collection to explain the recent decline in numbers of this species, and its conservation status. Has something similar been done with herbarium and/or plant genebank collections? I can’t think of any examples, but they must be out there…
According to this article in the Harare Herald, the Kellogg Foundation will be supporting research by University of Zimbabwe scientists into “wild and famine plant foods, their preparation and preservation (and) nutrient analysis … to enhance livelihood security.”
I spent the last few days in Portesham, Dorset (thanks, Lorna and Geoff!), which made it all the more weird to come across this article reprinted in a newspaper in Dubai, where I had to transit for a few hours on the way out there. But itÂ doesÂ show that you can still discoverÂ (or re-discover) new thingsÂ even in such a well-researched crop as apples in the UK. Of course, for every upbeat story, there’s a depressing one.
This EU-funded project has looked at all the national parks and reserves in Africa and assessed the contribution each makes to conserving biodiversity as part of the overall system of protected areas. Really an incredible job. Mainly dealing with animals, however, so I wonder if something similar could be done with things like wild crop relatives or something. Also, could these techniques be applied to in situ crop conservation?
