- Analysis of genetic diversity in farmers’ rice varieties in Sierra Leone using morphological and AFLP markers. Still a lot of diversity in traditional rice after the war, both among and within landraces, mostly among, organized regionally, and recognized by local names.
- Simultaneous selection for resistance to five bacterial, fungal, and viral diseases in three Andean × Middle American inter-gene pool common bean populations. Thanks goodness for multiple independent domestication events. And genebanks.
- Present Spatial Diversity Patterns of Theobroma cacao L. in the Neotropics Reflect Genetic Differentiation in Pleistocene Refugia Followed by Human-Influenced Dispersal. So need to collect in areas at the margins or just outside the refugia if you want high diversity. But of course that may already be ex situ. But wait, didn’t you just do the analysis based on the provenance of ex situ holdings?
- An ancient duplication of apple MYB transcription factors is responsible for novel red fruit-flesh phenotypes. The whole genome got duplicated during evolution of the apple and the red flesh phenotype is controlled by loci in both copies, but in different ways.
- What is the form of the productivity–animal-species-richness relationship? A critical review and meta-analysis. Positive.
- Spatial Structure and Climatic Adaptation in African Maize Revealed by Surveying SNP Diversity in Relation to Global Breeding and Landrace Panels. Distinct Sahelian, Western and Eastern clusters. Some SNPs associated with high temperatures.
- MtDNA analysis of global populations support that major population expansions began before Neolithic Time. Humans needed good weather to thrive, not agriculture.
- Genetic gap analysis of wild Hordeum taxa. Argentina?
- The Impact of Climate Change on Indigenous Arabica Coffee (Coffea arabica): Predicting Future Trends and Identifying Priorities. Generally very bad to disastrous, but some “core localities” will be ok, and therefore could be used for in situ conservation. Interestingly, genebank accession locality data not used.
- The genus Acacia (Fabaceae) in East Africa: distribution, diversity and the protected area network. No such luck for Acacia, I’m afraid.
- Monocropping Cultures into Ruin: The Loss of Food Varieties and Cultural Diversity. Are you sure you want to know what a sociologist and a political scientist have to say on the matter?
Nibbles: Tree diversity, Cacao strategy, IFPRI strategy, Caribbean strategy, Mango conservation strategy, Olive migrations, African cassava, African Striga, Ecosystem services, Model plant
- Oh gosh, it was Tree Diversity Day and nobody told us.
- Bioversity catch up with their own cacao strategy.
- And IFPRI has a new one for you to comment on.
- Caribbean agriculture gets another signed document to help it along. No word on whether agrobiodiversity featured.
- Mango conservation gets organized. But not to the extent of an RSS feed, alas.
- California owes Morocco for its olives.
- Virus-resistant cassava imminent. Haven’t they been saying this for a while now? And is anyone thinking about what will happen to the virus-susceptible varieties?
- Push-pull in the news.
- The cost of everything, and the value of nothing, nature edition.
- What’s the value of Arabidopsis, then?
Saving rice from a truant monsoon
Forsaken by the rain gods, the tribal farmers in the district are now mounting a desperate attempt to salvage their wilting crop. What is at stake is not only their livelihood, but also the preservation of over a dozen rare and invaluable indigenous varieties of rice. If the attempt by these farmers doesn’t succeed, the state could lose many rice varieties for ever…
“These tribal farmers have been the sole saviours of the seeds of many indigenous and rare varieties of rice. They have been cultivating and saving them religiously despite suffering losses as these varieties have only half the yield when compared to hybrid ones…”
Well, maybe. But Jeerakashala, Navara, Adukkan, Thondi and Chomala are in fact in IRRI’s genebank, according to Genesys.
Nibbles: Genetic erosion, Rural radio, PhD, Farm workers, Medlars
- Drought threatens rare rice varieties. What d’you mean they’re not in genebanks?
- Has video dimmed the radio’s star?
- Wanna get a PhD in “climate services for development“? Course you do.
- Apple harvest fails. Turns out you need a diversity of agricultural labourers too.
- Medlars. I love it when people treat my familiar stuff as highly exotic.
IUCN and Microsoft map threats to biodiversity
“We’re building an application that allows people to map those threats spatially,” Joppa explains. “We’re trying to provide a repository of evidence for threats to species.”
Lucas Joppa is talking about a collaboration between Microsoft and IUCN to map threats to biodiversity. Worth keeping an eye on. But I wonder if they’ll consider agrobiodiversity too. If so, we have some ideas here at the blog. Anyway, presumably the thing will link up with GeoCAT in some clever way.
LATER: And also link to this? Or at least suck in the data?
