Shapefiles reporting the boundaries of glaciers analyzed by applying a multifractal approach
<p>We recently investigated the multifractal properties of the perimeters of the Lombardy glaciers in the Italian Alps. We characterized the area and perimeter distributions of the population of glaciers and we showed that the distribution of perimeters exhibits a marked peak, not present in the distribution of areas. We investigated the multifractal spectra of perimeters and we showed that their features are strongly correlated with the area of the glaciers.</p> <p>Here are reported the shapefiles of the boundaries of glaciers of the Lombardia region measured in 2003, 2007, and 2012 that were used for this work.</p>

Data from: Repetitive DNA profiles reveal evidence of rapid genome evolution and reflect species boundaries in ground beetles
Genome architecture is a complex, multidimensional property of an organism defined by the content and spatial organization of the genome's component parts. Comparative study of entire genome architecture in model organisms is shedding light on mechanisms underlying genome regulation, evolution, and diversification; but such studies require costly analytical approaches which make extensive comparative study impractical for most groups. However, lower-cost methods that measure a single architectural component (e.g., distribution of one class of repeats) have potential as a new data source for evolutionary studies insofar as that measure correlates with more complex biological phenomena, and for which it could serve as part of an explanatory framework. We investigated copy number variation (CNV) profiles in ribosomal DNA (rDNA) as a simple measure reflecting the distribution of rDNA subcomponents across the genome. We find that signatures present in rDNA CNV profiles strongly correlate with species boundaries in the <i>breve</i> species group of <i>Bembidion</i>, and vary across broader taxonomic sampling in <i>Bembidion</i> subgenus <i>Plataphus</i>. Profiles of several species show evidence of re-patterning of rDNA-like sequences throughout the genome, revealing evidence of rapid genome evolution (including among sister pairs) not evident from analysis of traditional data sources such as multi-gene data sets. Major re-patterning of rDNA-like sequences has occurred frequently within the evolutionary history of <i>Plataphus</i>. We confirm that CNV profiles represent an aspect of genomic architecture (i.e., the linear distribution of rDNA components across the genome) via fluorescence in-situ hybridization. In at least one species, novel rDNA-like elements are spread throughout all chromosomes. We discuss the potential of copy number profiles of rDNA, or other repeats, as a low-cost tool for incorporating signal of genomic architecture variation in studies of species delimitation and genome evolution.
