The juice and pulp of the fruits of the Amazonian palm Euterpe oleracea (açaí) have long been consumed locally but are increasingly used in juices and nutraceutical beverages aimed at the North American market. They are harvested from the wild, but some people are now thinking plantations too. But speaking of wild harvesting of fruits/nuts, this article suggests that this can be sustainable only where it is not accompanied by hunting of key seed dispersers.
Fido not a domesticated wolf?
Domestic dogs are derived from wolves, right? Maybe not. There is apparently a minority view that says that a better interpretation of behavioural, morphological and genetic differences between the domestic dog and the wolf is that the dog was domesticated from a now-extinct, pariah-like precursor, with occasional hybridization with wolves along the way. You can read more about this controversial view on Darren Naish’s zoological blog.
Grape origins
A paper in Conservation Genetics identifies (not, I think, for the first time) the Caucasus as the centre of diversity and origin of wild grapevine, at least based on microsatellites. A genetic refugium was detected in Sardinia, and it would be interesting to know whether the plastid lineage that is fixed there is responsible for the high levels of procyanidins in some local wines.
Farming tigers
Not agricultural biodiversity, but here’s a somewhat radical (in its context) take on conservation through use. Of course, this strategy is fairly well established for wild plants.
African Vegetables — “not without merit”
Many people interested in crop diversity have on their bookshelves the “Lost crops …” series published by America’s National Academies of Science. They detail neglected species of South America and Africa, gathering the kind of summary data that is so hard to find in one place. A new volume on African Vegetables has just been published, and it looks really interesting. From the blurb:
The report examines the promise of 18 African vegetables to help feed the continent’s growing population and spur sustainable development. These native vegetables – including amaranth, cowpea, and egusi – are still cherished in many parts of Africa, and even attract some research interest, but they are typically overlooked by scientists and policymakers in the world at large. In the past, these local plants may have been judged less valuable than the well-known vegetables introduced to Africa from other parts of the world. But because few indigenous vegetables have been studied extensively, information about them is often outdated, difficult to find, or largely anecdotal. Despite this neglect, they are not without merit, the report emphasizes.
The printed copy is expensive. But for anyone with a good internet connection, the entire thing is available for reading — and searching — online from the NAS web site.
Volume 1, covering grains, came out in 1996. Volume 3 will cover African Fruits. Let’s hope it arrives before 2016.
