We are pleased to announce the publication (online at this stage) of the 
following short communication in Mammalian Biology:

First mitochondrial DNA analysis of the spectacled porpoise (Phocoena 
dioptrica) from Tierra del Fuego, Argentina

Abstract
The spectacled porpoise (Phocoena dioptrica, Lahille, 1912) is one of the 
cetacean species about which least is known. Most information on the biology 
and ecology of this species has been obtained from stranded specimens and 
sightings at sea. In this study, analysis of 380 bp fragment of mitochondrial 
DNA (mtDNA) control region sequences (N = 50) was performed to provide a 
preliminary assessment of the genetic variation in spectacled porpoise 
specimens found stranded or by caught on the coast of Tierra del Fuego, 
Argentina. Results showed high levels of mtDNA diversity, as expected in large 
size and stable populations, and similar to other species of porpoises. The 
star-like shape phylogeny of haplotypes indicates a recent population 
expansion. This is the first report on the genetic variation of this species. 
Other lines of evidence (microsatellite loci, single-nucleotide polymorphism 
(SNPs)) are needed to improve our knowledge on the molecular biology of the 
spectacled porpoise.
