Nothing as nasty as that, Helen.

A colleague at work is interested in the current distribution of podocarps (a type of plant) in the Blue Mountains and how this might relate to their distribution (as indicated by analysis of pollen trapped in swamp sediments) in the early Holocene and late Pleistocene. One path to understanding involves checking the distribution of their pollen from current plant communities that have podocarps. The easy way is to construct pollen traps and deploy these according to a reasonable hypothesis; then you can analyse the distribution(s) of types and quantities of pollen collected.

In a past life we used to use beer bottles with their bottoms cut off and the necks stoppered with a cork; plastic soft drink bottles with screw caps are much easier and I've been collecting and constructing on his behalf.

But I can't (yet) think of any relevant songs or tunes.

Cheers, Rowan
