Variation of chemical compounds in wild Heliconiini reveals ecological factors involved in the evolution of chemical defenses in mimetic butterflies. [PDF]

open access: yesEcol Evol, 2020
Within Heliconiini butterflies, we show that ecological factors such as mimetic interactions and host plant specialization have a significant effect on chemical profiles, but these effects are largely explained by phylogenetic relationships. Our results suggest that shared ancestries largely contribute to chemical defence variation, pointing out at the

Multi-allelic major effect genes interact with minor effect QTLs to control adaptive color pattern variation in Heliconius erato. [PDF]

open access: yesPLoS ONE, 2013
Recent studies indicate that relatively few genomic regions are repeatedly involved in the evolution of Heliconius butterfly wing patterns. Although this work demonstrates a number of cases where homologous loci underlie both convergent and divergent ...

Le sferette bronzee iscritte da Himera [PDF]

open access: yesKernos, 2011
The focus of the study is (§ 1) the analysis of an inscribed bronze spherule discovered in the temenos on the Piano di Imera. The document belongs to a small group of similar inscriptions, consisting of three bronze spherules inscribed with a sample formulaic structure: the divinity’s name.

Himera

open access: yes
In this thesis, I will discuss the ancient Greek city located in the north of the island of Sicily. It existed for only about 250 years but was a witness and a participant in both major wars that took place during the classical Greek period. In the so-called Greco-Persian Wars it emerged on the side of the victors, and in the Peloponnesian War, it was ...

La memoria del tiranno: Anassilao di Reggio tra protagonismo personale e oblio letterario

open access: yesHistorika : Studi di Storia Greca e Romana, 2022
Questo articolo si propone un duplice obiettivo. Innanzitutto, vuole analizzare come Anassilao sfruttò i contesti performativi e i canali comunicativi che, nei primi decenni del V  secolo a.C., erano a disposizione dei tiranni di Magna Grecia e Sicilia ...

Scale‐dependent environmental effects on phenotypic distributions in Heliconius butterflies

open access: yesEcology and Evolution, Volume 12, Issue 9, September 2022., 2022
Using a multiscale approach and different Heliconius butterfly phenotypes, we investigated how the environment shapes the distribution of mimetic wing color patterns and assessed the overlap of co‐mimics' distribution. Abstract Identifying the relative importance of different mechanisms responsible for the emergence and maintenance of phenotypic ...

Defining the speciation continuum

open access: yesEvolution, Volume 75, Issue 6, Page 1256-1273, June 2021., 2021
Abstract A primary roadblock to our understanding of speciation is that it usually occurs over a timeframe that is too long to study from start to finish. The idea of a speciation continuum provides something of a solution to this problem; rather than observing the entire process, we can simply reconstruct it from the multitude of speciation events ...

Geoelectrical study of archaeological structures in the Himera plane (North-western Sicily)

open access: yesAnnals of Geophysics, 1996
This paper presents the results obtained from a geoelectrical study carried out on the Himera plane for archaeological research. Both the tripotential method and the dipole-dipole profile method have been used on a 40 m ´ 40 m investigation area in order
