Sequence and expression of the hunchback gene in Lucilia sericata: a comparison with other Dipterans

We have found that the hunchback (hb)gene from Lucilia sericata is conserved in its functional domains in comparison with related flies, although there is divergence in the protein outside these regions. The expression patterns of Lucilia hb in early embryos are broadly similar to other higher Dipterans. However, in the posterior region we report blastoderm and post-gastrulation expression patterns, which are diverged from Musca and Drosophila. These patterns are reminiscent of hb expression in more primitive insects and could be indicative of changes in the regulation of hb in Lucilia by the terminal system.     

Grassland butterflies and low intensity farming in Europe

In this paper we describe the impact of the abandonment of traditional farming practices on butterflies and their habitats in traditional, often montane, pastoral systems. We link these declines to socioeconomic factors: illustrating how the failure of the CAP to support traditional farming leads to structural changes in farming enterprises??features which may be obscured by crude statistics on stock. We then call for the scheduled CAP reforms in 2013 to be radically realigned to support rather than destroy biodiversity so that any new EU agri-biodiversity commitments have an effective funding stream to support them.
