- Can Ficus Sp. Forests Be Restored Through Vegetative Propagation? Yes. But with the reduced genetic diversity and all, for how long?
- A qualitative assessment of diversity and factors leading to genetic erosion of vegetables: a case study of Varamin (Iran). Species richness only, settle down. But, pace the title, quantitative.
- Agricultural intensification escalates future conservation costs. Because of higher land rents. Just can’t win.
- Common property protected areas: Community control in forest conservation. They can work.
- Baja California peninsula oases: An agro-biodiversity of isolation and integration. Both too much and too little isolation are bad.
- Cultivated, caught, and collected: defining culturally appropriate foods in Tallé, Niger. …and integrating them into development.
- Wetlands in Europe: Perspectives for restoration of a lost paradise. Down to 20% and counting. Someone should count the crop wild relatives in them.
- Economic Resilience and Land use: The Cocoa Crisis in the Rio Cachoeira Catchment, Brazil. Diverse land use means more resilience.
- Priorities for biodiversity monitoring in Europe: A review of supranational policies and a novel scheme for integrative prioritization. Yeah, but doesn’t integrate crop wild relatives, does it?
Conserving Prunus africana?
I’ve been sitting on it for a while, but a paper which AoB Blog discussed back in January led me to uncover a whole load of stuff on Prunus africana. The African Cherry Tree does not rate a leaflet in the African Food Tree Species series, perhaps because it’s not a, well, food tree, but that doesn’t mean it’s not important.
Chemicals extracted from the tree’s bark are used in a range of pharmaceutical products to treat enlarged prostate (benign prostatic hyperplasia), an extremely common condition that affects up to half of men aged over 50.
Hence various efforts to develop sustainable harvesting methods. And also an interesting series of diversity and demographic studies:
- Phylogeography of the Afromontane Prunus africana reveals a former migration corridor between East and West African highlands: “The high genetic similarity found between western Uganda and west African populations indicates that a former Afromontane migration corridor may have existed through Equatorial Africa.”
- Structural diversity and regeneration of the endangered Prunus africana (Rosaceae) in Zimbabwe: “…poor regeneration, fewer P. africana trees in small and large size classes, dominance of positive height and diameter differentiation and high mingling.”
- Divergent pattern of nuclear genetic diversity across the range of the Afromontane Prunus africana mirrors variable climate of African highlands: “The observed patterns indicate divergent population history across the continent most likely associated to Pleistocene changes in climatic conditions. The high genetic similarity between populations of West Africa with population of East Africa west of the Eastern Rift Valley … provides further evidence for a historical migration route. Contrasting estimates of recent and historical gene flow indicate a shift of the main barrier to gene flow from the Lake Victoria basin to the Eastern Rift Valley…”
- Modelling the potential distribution of endangered Prunus africana (Hook.f.) Kalkm. in East Africa: “Prunus africana distribution is thus highly vulnerable to a warming climate and highlights the fact that both in-situ and ex-situ conservation will be a solution to global warming.”
Maybe we could do with some more seed behaviour data. But it would seem there is now plenty of diversity, demographic and sustainable harvesting information on which to base a comprehensive conservation strategy. Is someone coming up with one?
Nibbles: GMO promises promises, African livestock outside & in, Vegetables galore, Farmer videos from US & Sri Lanka, Fermentation beery & otherwise, Yam people & traits, Botanic garden diversity, ECPGR, CWR in US & Benin, Herbarium data, Baobab info, Olean info, Pix, Indian cooking
- Nature “celebrates” 30 years of GMOs.
- African pastoralists know how not to destroy their livelihoods shock.
- African urban dwellers keep livestock shock.
- Vegetables can be perennial too. Oh yes indeedy. Not bitter gourd though, alas. Nor cucumber. And in other news, there’s a Bitter Melon Council. And also a campaign to promote zucchini in Iowa.
- Climate change reaches farmers in the Pacific NW. Can their Sri Lankan colleagues be far behind?
- Always good to have a beer story. Well, maybe not.
- Speaking of fermentation, this WSJ piece looks interesting, from the two sentences of it I can read. No, wait. Oh crap, try this.
- A hummus dip goes really nicely with beer. Is this the quinoa story again?
- A yam conference for the ages. Will they discuss the new trait ontology?
- Botanic gardens reach out. Genebanks next? Maybe not.
- You mean like the European ones, perhaps?
- That US CWR paper from the horse’s mouth. And a similar thing from Benin. But where does all that data come from?
- Baobab notes to go with all those factsheets.
- The Saharan olive needs a factsheet too. IRD obliges.
- Cool set of agriculture photos.
- A couple of different views of Indian food. Thanks to Cara de Silva and Diana Buja.
Nibbles: African food, Cattle grazing, Young farmers, Seed policy, Traditional medicine, Litchis, Land use, Perennial sorghum
- Today’s Nibbles is a Kenya edition. Just because.
- But we’ll start with an African foodie revolution that is passing that country by.
- Cattle need diverse foods too, so don’t neglect those forbs, Kenyans.
- A young Kenyan turns to vegetable growing. Not, alas, of the traditional kind. Yet.
- Well, he better get a move on, because it says here people are after his seeds.
- Seeds are what the traditional medicine industry could do with.
- I guess there’s always litchis.
- Wonder what they’ll do to land use patterns.
- But will there ever be perennial sorghum?
Nibbles: FAO Commission, Alpine plants conference, Young breeders, Indian sorghum, Pastoralists in the media, Neglected genomics, More quinoa, Cape Gooseberry in Europe, Database hell, Tomayto tomahto, Maple syrup, Double cropping, Cloning trees, Belated Earth Day, UK Plant Science Week
- Summary of that 14th Session of the CGRFA we were all following last week.
- Conferences on “Changes in alpine and arctic flora under climate change” we’ll all be following in September. If you’re from Balkans, Caucasus, Central Asia, the organizers need you in particular. But hurry, before it’s too late!
- In other news, young scientists are into beer.
- India’s Directorate of Sorghum Research gets a genebank. Relationship with NBPGR unclear.
- Media portrayals of pastoralists in Kenya, China and India: The Report. The Brief. The Press Release. ILRI reaction?
- Neglected crops get the genomic treatment. And why that might be a good thing.
- CIAT wades in on quinoa.
- Call for information on Physalis peruviana cultivation in Europe.
- Biodiversity databases have errors! Shock! Horror! Probe!
- The nutritional difference between organic and conventional tomatoes deconstructed.
- Your maple sugaring questions answered. Nice idea.
- Double crop for development. I guess that’s the sustainable intensification everyone is talking so much about.
- If in doubt, clone it!
- Wait, wait, wait, we missed Earth Day?
- And also a bunch of UK plant science conferences. (I had of course linked to the storifications here originally, but they’ve gone now of course.)
