Aggregating taxon data online
At first I just wanted to Nibble it. “Alien plants in urban nature reserves: from red-list species to future invaders?” ((Jarošik V, Pyšek P, Kadlec T (2011) Alien plants in urban nature reserves: from red-list species to future invaders?. NeoBiota 10: 27-46. doi: 10.3897/neobiota.10.1262)) 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. ((Genesys too one day, I would hope.)) And not a factsheet in sight.

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.
