Spotlight on islands.On the origin and diversification of an ancient lineage of the Italian wall lizard Podarcis siculus in the western Pontine Islands [PDF]

open access: yes, 2018
Groups of proximate continental islands may conceal more tangled phylogeographic patterns than oceanic archipelagos as a consequence of repeated sea level changes, which allow populations to experience gene flow during periods of low sea level stands and

A simple DNA based method for determination of pure Black Slavonian pigs

open access: yesItalian Journal of Animal Science, 2010
The aim of this work was to determine the MC1R genotype of Black Slavonian pigs and to find an efficient and simple PCR-RFLP method, based on differences in MC1R genotype, to distinguish between purebred Black Slavonian pigs and their crossings with ...

The protective role of MC1R in chromosome stability and centromeric integrity in melanocytes

open access: yesCell Death Discovery, 2021
Variants in the melanocortin-1 receptor (MC1R) gene, encoding a trimeric G-protein-coupled receptor and activated by α-melanocyte-stimulating hormone (α-MSH), are frequently associated with red or blonde hair, fair skin, freckling, and skin sensitivity ...

Evolutionary and demographic correlates of Pleistocene coastline changes in the Sicilian wall lizard Podarcis wagleriana [PDF]

open access: yes, 2019
Aim Emergence of coastal lowlands during Pleistocene ice ages might have provided conditions for glacial expansions (demographic and spatial), rather than contraction, of coastal populations of temperate species. Here, we tested these predictions in the

The genetic basis of color-related local adaptation in a ring-like colonization around the Mediterranean. [PDF]

open access: yes, 2015
Uncovering the genetic basis of phenotypic variation and the population history under which it established is key to understand the trajectories along which local adaptation evolves.

Nucleotide diversity and population differentiation of the Melanocortin 1 Receptor gene, MC1R [PDF]

open access: yesBMC Genetics, 2008
The melanocortin 1 receptor gene (MC1R) is responsible for normal pigment variation in humans and is highly polymorphic with numerous population-specific alleles. Some MC1R variants have been associated with skin cancer risk.Allele frequency data were compiled on 55 single nucleotide polymorphisms from seven geographically distinct human populations (n
