- Mapping climatic mechanisms likely to favour the emergence of novel communities. New climate combinations are rare (3.4% of evaluated cells), but mean displacement moderately rapid (3.7 km per decade) and divergence high (>60° for 67% of cells). What will all this mean for CWR? As many are ruderals, maybe nothing?
- Why biodiversity matters. Inaugural issue of Nature Ecology & Evolution. Not much on agricultural biodiversity, alas.

The perils of reduced diversity: animal edition
To the standard hymn-sheet of crop failures associated with genetic erosion we can now add an example from livestock. A mutation in a single Holstein bull — Pawnee Farm Arlinda Chief, who happens to father super-productive daughters — also causes spontaneous abortion. The mutation spread through the US dairy industry and caused $420 million in losses.
That’s a crazy number, but here’s an even crazier one: Despite the lethal mutation, using Chief’s sperm instead of an average bull’s still led to $30 billion dollars in increased milk production over the past 35 years.
There’s nothing like that, at least not that I can think of, for crops, but it is just one of the nuggets in a super piece from The Atlantic magazine on selective breeding.
