- European white stork are long considered to diverge to eastern and western migration pools as a result of independent overwintering flyways. In relatively recent times, the western and northern distribution has been subject to dramatic population declines and country-specific extirpations. A number of independent reintroduction programs were started in the mid 1950s to bring storks back to historical ranges. Founder individuals were sourced opportunistically from the Eastern and Western European distributions and Algeria, leading to significant artificial mixing between eastern and western flyways. Here we use mitochondrial and microsatellite DNA to test the contention that prior to translocation, eastern and western flyways were genetically distinct. The data show a surprising lack of structure at any spatial or temporal scale suggesting that even though birds were moved between flyways, there is evidence of natural mixing prior to the onset of translocation activities. Overall a high retention of genetic diversity, high N-ef, and an apparent absence of recent genetic bottleneck associated with early 20th century declines suggest that the species is well equipped to respond to future environmental pressures.

- The Tudor warship the Mary Rose sank in the Solent waters between Portsmouth and the Isle of Wight on the 19th of July 1545, whilst engaging a French invasion fleet. The ship was rediscovered in 1971 and between 1979 and 1982 the entire contents of the ship were excavated resulting in the recovery of over 25,000 objects, including the skeleton of a small to medium sized dog referred to as the Mary Rose Dog (MRD). Here we report the extraction and analysis of both mitochondrial and genomic DNA from a tooth of this animal. Our results show that the MRD was a young male of a terrier type most closely related to modern Jack Russell Terriers with a light to dark brown coat colour. Interestingly, given the antiquity of the sample, the dog was heterozygotic for the SLC2A9 gene variant that leads to hyperuricosuria when found in modern homozygotic animals. These findings help shed light on a notable historical artefact from an important period in the development of modern dog breeds.
