>1. Does anyone know what method of carbon fixation the CPs employ (i.e.

Not that I know. Studnicka has discovered succulent structures in the
leaves of some _Pinguicula_ spp., and I think he has at least suggested CAM
in these.

Only morphological work AFAIK.

Quite a lot of other work (esp. on secretion, nutrient uptake, etc., much
of which cited in Juniper & al., The Carnivorous Plants, 1989) has been
published.
The group I am working in is investigating the secondary metabolism in the
clade which contains Nepenthaceae. We are especially interested in the
pathway leading to plumbagin in Droseraceae, Nepenthaceae,
Ancistrocladaceae & al.
Kind regards
