What is it about?
It assesses areas remaining globally for an extremely endangered taxon, Acipenseriformes. Sturgeons are affected by fragmentation through habitat change, isolation of populations and access to traditional spawning and nursery areas. While this probably has not caused the decline of sturgeons, to the most part, it inhibits recovery and reduces their productive capacity. This helps ascertain important areas globally that may be refuges for sturgeon.

Why is it important?
This study identifies areas globally where rivers have not be altered and sturgeon are not considered at risk. Only a small area in northern Canada remains for a taxon that was historically abundant and considered 'living fossils'.
Perspectives
Despite being written almost a decade ago, this study's relevance is even more important in time of seeking more remote areas for development and mineral exploration.
