Genome duplication events and functional reduction of ploidy levels in sturgeon (Acipenser, Huso and Scaphirhynchus).
Results suggest that gene silencing, chromosomal rearrangements, and transposition events played an important role in the acipenseriform genome formation and reveal a highly supported oceanic subdivision within the Acipenser/Huso complex. Expand

This work aims to demonstrate the efforts towards in-situ applicability of EMMARM, which aims to provide real-time information about the phytochemical properties of E.coli and its role in fish establishment and behaviour. Expand
Origin and History of Mitochondrial DNA Lineages in Domestic Horses
At least seventeen haplotypes of early domestic horses have become extinct during the last 5,500 years, suggesting the large diversity of mtDNA lineages is not a product of animal breeding but, in fact, represents ancestral variability. Expand
The molecular phylogeny of the order Acipenseriformes revisited
Results offer further evidence that some revision of acipenseriform classification may be needed to accurately inform conservation efforts and that future phylogenetic studies of this group should focus on the analysis of nuclear genes. Expand

- 1 November 2011
The underlying causes that have resulted in the observed increase of colour variation in domesticated animals compared to their wild ancestors are focused on, and the current state of knowledge with regard to the molecular mechanisms of colouration is examined, with a special emphasis on when and where the different coat‐colour‐associated genes act.

Identification of Acipenseriformes species in trade
- A. Ludwig
- 14 April 2008
There is not a single method that can meet all requirements of an identification system for Acipenseriformes species and their products in trade, and it does not appear to be feasible to develop such a method in the near future therefore the most appropriate methods need to be developed for each.

First evidence of hybridization between endangered sterlets (Acipenser ruthenus) and exotic Siberian sturgeons (Acipenser baerii) in the Danube River
Genotypes and morphotypes of Siberian sturgeon (Acipenser baerii) are observed, as well as hybrids between this species and native sterlets, which demonstrates the risk of extinction by hybridisation of endangered populations. Expand
Heteroplasmy in the mtDNA control region of sturgeon (Acipenser, Huso and Scaphirhynchus).
The data demonstrate that heteroplasmy is present in most sturgeon species and suggest that the thermal stability of the secondary structure of the repeat unit in combination with mutations downstream of the TAS sequences influences heteroplAsmy. Expand
Coat Color Variation at the Beginning of Horse Domestication
It is concluded that it is unlikely that horse domestication substantially predates the occurrence of coat color variation, which was found to begin around the third millennium before the common era. Expand
GENETIC STRUCTURE OF POPULATIONS OF EUROPEAN BROWN HARE: IMPLICATIONS FOR MANAGEMENT
Analysis of molecular variance revealed a high degree of genetic variability, matrilinearily structured populations, male-biased gene flow, and lack of inbreeding in European brown hare populations. Expand
