The humble flour beetle is about to play a major role in the management of endangered species
Huge impacts sometimes come from humble unexpected
sources. What scientists have achieved
with the flour
beetle (Tribolium castaneum) recently
is a case in point. Scientists have been working with various organisms
in their pursuit to get to the roots of genetic erosion and consequent extinction.
They have now and zeroed in on the flour beetle as the perfect tool to work
with. Flour beetle will be the model in a major new study of University of East
Anglia, seeking answers to the consequences of inbreeding.
When the gene pool is
reduced it brings about inbreeding between relatives. This entails losses in
genetic variability and is a causative factor for the decline of many species
around the world. The project will determine how much new variability must be
re-introduced to genetically rescue an inbred population. This is bound to give
a huge boost to the working resources of managers of conservation and captive
breeding projects. They are indeed a delighted lot.
