BACKGROUND The chamois, distributed over most of the medium to high altitude mountain ranges of southern Eurasia, provides an excellent model for exploring the effects of historical and evolutionary events on diversification. Populations have been grouped into two species, Rupicapra pyrenaica from southwestern Europe and R. rupicapra from eastern Europe.(More)
Evolutionary relationships among populations of chamois (Rupicapra spp.) across their current range from the Caucasus to the Cantabrian Mountains were investigated. The allelic variation in 23 microsatellite loci was assessed in eight geographical populations, recognised as subspecies of the two closely related species R. pyrenaica and R. rupicapra.(More)
Most current methods to assess connectivity begin with landscape resistance maps. The prevailing resistance models are commonly based on expert opinion and, more recently, on a direct transformation of habitat suitability. However, habitat associations are not necessarily accurate indicators of dispersal, and thus may fail as a surrogate of resistance to(More)

Random amplified polymorphic DNA (RAPD) fragment reproducibility was assayed in three animal species: red deer (Cervus elaphus), wild boar (Sus scrofa) and fruit fly (Drosophila melanogaster). Ten 10-mer primers (Operon) were tested in two replicate reactions per individual under different stringency conditions (annealing temperatures of 35 degrees C or 45(More)
DNA fingerprinting allows the verification of conventional methods used to implement beef traceability. At any point along the supply chain, the identity of an animal or piece of meat can be checked by comparison of its DNA profile with an initial sample. Practical application of DNA fingerprinting to trace beef requires a choice of DNA markers as well as(More)
Microsatellite mutations were studied in a set of 175 mutation accumulation lines, all of them independently derived from a completely homozygous population of Drosophila melanogaster and maintained under strong inbreeding during 80 generations. We assayed 28 microsatellites and detected two mutations. One mutation consisted of a single addition of a(More)
This paper explores the use of MRI (Magnetic Resonance Imaging) in combination with a fully automated Image Analysis method for the recognition of Biceps Femoris and Semimembranosus muscles in Iberian ham. A quantitative description of volume and a study of moisture and weight relationships during the product's ripening process are included. Three Active(More)
The chamois provides an excellent model for exploring the effect of historical and evolutionary events on diversification. We investigate cytochrome b (cytb) sequences in the 10 recognized subspecies of Rupicapra classified within 2 species: Rupicapra pyrenaica, with the subspecies parva, pyrenaica, and ornata, and Rupicapra rupicapra, with cartusiana,(More)
Hypervariable minisatellite DNA probes 33.15 and 33.6, originally developed for studies in human populations, were used to study genetic variation in chamois (Rupicapra rupicapra). The mean number of bands per individual was 25 for probe 33.15 and 15 for probe 33.6. The average band frequency was 0.33 for both probes. The mean similarity was 0.44, greater(More)
