Yabbies, crayfish, crawdads, call them what you will, but one-third of the world’s crayfish species are facing extinction according to a recent report by a team of 40 international scientists.

A Genomic Approach to Pathogen Identification
Burrowing Crayfish Species Mapped
Genetic Analysis Suggests Dwarf Crayfish Share Ancestor
Review article authored by CBI researchers highlights the strengths and challenges associated with multi-locus sequence typing (MLST), a high-resolution genetic typing approach to identify species and strains of pathogens impacting human health, agriculture (animals and plants) and biosafety.
In this study, researchers mapped the habitat and evolutionary lineage of burrowing crayfish by analyzing five genes in 19 species of Fallicambarus. The genus Fallicambarus consists entirely of primary burrowers-- crayfish that inhabit burrows for all of their lives. The burrows can have a negative impact when their habitat overlaps with human land-based activities such as farming. Because Fallicambarus is distinct from stream-based crayfish species, habitat shift may impact migration, speciation and conservation.
Though similar in appearance, researchers were unsure if Dwarf crayfish found in distinct locations along the Gulf Coast of United States and into Central México were members of a the same taxonomic genus. Analysis of samples collected at 59 locations support the hypothesis that the Gulf and Mexican Groups shared a common ancestor roughly 40 million years ago. It is likely that the Cambarellus genus became separate groups following changes in geographical barriers and climate, possibly related to the Eocene-Oligocene boundary.
