Our laboratory is currently involved in several basic studies on butterflies that can be applied to the field of Conservation Biology
Spatial and temporal patterns of genetic variation, phylogeography and ecological niche modelling approachAnalyses of the genetic population structure at different geographic scales and by different molecular tools has been addressed to improve empirical estimation of evolutionary parameters and processes for several butterfly species. Populations of mountain species, displaying similar geographic distributions, but different ecological requirements, have offered a unique opportunity for investigating the influence of past climate changes in assembling the diversity of European biotas. Phylogeographic comparative analysis and Bayesian coalescent approaches are applied to obtain a detailed depiction of the history of European populations through the Pleistocene. The Bayesian inference used to clarify past demographic trends of species is compared to ecological niche modelling analysis in order to theorize present, past and future potential distribution of species.
Phylogeny, biogeography and DNAbarcode of Sino-Himalayan butterfliesResearch on taxonomy, molecular phylogeny, zoogeography and mtDNA (COI) sequences for DNA Barcode are currently in progress for several butterfly taxa showing Sino-Himalayan distribution patterns. We are particularly interested in the times and modes of the cladogenetic events leading to the evolution of several Sino-Himalayan speciose butterfly genera. Stepwise speciation events revealed over time are analysed in relation to the complex topography of this region, with steep mountains alternated to deep valleys resulting in a wide range of local climatic conditions, whereas tectonic and other historical processes could have driven older cladogenetic processes.
Taxonomic and faunistic studies of butterflies and mothsBesides a collection of birds from Italy, our laboratory houses remarkable collections of butterflies from around the world and Italian moths, that represent the basis to perform taxonomic and morphological studies (including genitalic structures) as well as faunistic researches at regional level carried out on behalf of the Observatory for Biodiversity of Latium (OBL) by means of biodiversity databases and GIS.
Ethology and mating behaviourThe evolutionary history of courtship behaviour allows to characterize the mating signals involved in species recognition. Experiments have been performed to describe and compare courtship behaviour among Hipparchia species and to show the degree of change in courtship sequence with respect to species relatedness. The study of some aspects of reproductive behaviour of Euphydryas aurinia are also in progress. In collaboration with M.Santonico, G.Pennazza, A.D'Amico, C.Di Natale (Engineering) and R.Paolesse (Chemistry), the species-specific chemical stimuli involved in courtship in two cryptic Hipparchia species have been studied by using an “Electronic Nose”, developed at the Dept. of Electronic Engineering and the Dept. of Chemistry (Tor Vergata University).
