At first I just wanted to Nibble it. “Alien plants in urban nature reserves: from red-list species to future invaders?” 1 looks at the effect of invasive plant species on the flora of 48 protected areas in the city of Prague. I was going to ask how many crop wild relatives are to be found in those reserves and leave it at that. Oh, ok maybe also make a throwaway comment along the lines of: In other news, Prague has 48 nature reserves. But I think it may be worth additionally pointing out an interesting feature that comes from publishing in the free-access journal NeoBiota. If you click on any of the taxon names in the HTML version of the paper you get a so-called PENSOFT Taxon Profile. What that seems to do is aggregate in a really attractive way a whole bunch of content on the species in question from everything from GBIF to Wikipedia to Google Scholar. You can create your own taxon profile if a species you really want to know about isn’t named in the paper you’re looking at. Compare to how the Crop Wild Relatives Portal does it. Good and less good things in both, I suppose. I like the way PENSOFT actually gives you the GBIF map and the images, plus also gene sequence references. But the Portal includes SINGER, Eurisco and GRIN searches. 2 And not a factsheet in sight.

- Rice yields and yield gaps in Southeast Asia: Past trends and future outlook. If average farmers became like best-yielding farmers that would meet 2050 needs, except in the Philippines, where some more structural stuff is needed.
- Method of evaluating diversity of carrot roots using a self-organizing map and image data. The sound you hear is that of butterflies being broken on wheels.
- Bioactive compounds from Capparis spinosa subsp. rupestris. Are pretty much the same as those in subsp. spinosa.
- Constitutive Overexpression of the OsNAS Gene Family Reveals Single-Gene Strategies for Effective Iron- and Zinc-Biofortification of Rice Endosperm. So that’s a good thing, right?
- Analysis of climate paths reveals potential limitations on species range shifts. Corridors not the answer. Or not the only answer. Or not the full answer.
- An updated review of Adansonia digitata: A commercially important African tree. Do baobab scientists not sometimes long for the Time Before Reviews, when they actually, you know, did stuff?
- Genetic diversity, population structure and relationships of Tunisian Thymus algeriensis Boiss. et Reut. and Thymus capitatus Hoffm. et Link. assessed by isozymes. Dad, what’s an isozyme? Ah, son, it’s a thing people used in the Time Before DNA. The two species are different, they need to be managed in different ways.
- Potential Impact of Biotechnology on Adaption of Agriculture to Climate Change: The Case of Drought Tolerant Rice Breeding in Asia. Kinda pointless: “in severe drought both the [drought tolerant] and the conventional varieties were either not planted or, if planted, did not yield”.
To corridor or not to corridor
The fact that distribution change occurs predominantly through spatially restricted, local population processes suggests that the development of ecological networks may be an effective conservation strategy for plant species in the UK (Lawton et al. 2010). An ecological network comprises sites which collectively contain the diversity and area of habitat needed to support species and which have ecological connections between them. The UK is largely made up of semi-natural habitats shaped by human land use, and so consequently, much of the UK’s wildlife is restricted to small fragmented areas of high habitat quality. These can rarely be restored to large unbroken areas of natural habitat. However, making connections between them through wildlife corridors and smaller ‘stepping stone’ sites is a much more feasible option, which would improve species ability to track environmental change through short-range colonisation (Hilty, Lidicker & Merenlender 2006).
…constraints imposed by climatic variability, limited dispersal and low persistence may mean that even habitat corridors through high-quality habitat may not in themselves make range shifts possible. Additionally, corridors for species that show high uncertainty between climate paths under different GCMs are less likely to be effective.
These are from papers in Journal of Ecology and Ecology Letters published within days of each other, though admittedly one dealing with plant species in Britain the other with amphibians in the USA. So what’s a poor boy to do? Stop thinking there’s one solution for everything, I suppose. And get everything into ex situ just in case.
Building a plant conservation toolkit
70 per cent of the genetic diversity of crops including their wild relatives and other socio-economically valuable plant species conserved, while respecting, preserving and maintaining associated indigenous and local knowledge.
That would be Target 9 of the Global Strategy for Plant Conservation, and we are all fully behind it, and all the others, of course. How to do it, though? Well, the new Plants 2020 website is planning to provide a toolkit in due course. 3 When? Well:
Please check back regularly for updates and new information.
Ugh. Yep. No RSS feed. Look, I know I’m nay-saying again, and that it’s really boring. But no RSS feed these days is just not on. I hope they’ll fix that soon because this will be an important resource, and I want to keep up to date without having to check back regularly.
Crawling the web for agrobiodiversity threats
We have often mused here — mainly idly, it must be said — about the possibility of an automated, internet-based system for monitoring the threat of genetic erosion. While we muse, it seems, others roll their sleeves up and, well, do stuff. Welcome to the Threat News Explorer, news of which has reached us via Resilience Science. We’re talking here about “multiple interacting threats (wildfire, insects, disease, invasive species, climate change, land use change)” to “wildlands,” rather than agricultural biodiversity, and so far it looks like mainly in the US. But still, it’s a start. And perhaps of interest to our friends working on the crop wild relatives of the US.
LATER: If you were doing agrobiodiversity threats, you might look at new disease records, for example…
